Alternative Sources of Energy Essay

When will we switch to renewable sources of energy? Such as solar, wind, hydro, and geothermal power. In this Alternative Sources of Energy essay, the author argues that the Sun and wind have the potential to reduce our dependence on fossil fuels and lower carbon emissions. Read the paper to learn about the challenges, limitations, and benefits of implementing alternative energy sources. A particular part is dedicated to the importance of government policies in promoting the development and use of alternative energy sources. Overall, the essay on alternative sources of energy presents a comprehensive overview of the current state of renewable energy and its potential for shaping our future.

Introduction

Solar power, course of action, works cited.

The world has been overly relying on oil as a source of energy to fuel most of its operations. It is important to note that as much as 80% of the world’s energy comes from fossil fuel. Unfortunately, the fossil deposits we have in the world cannot last forever. They will be depleted one day and cause a lot of problems in the world.

Therefore, efforts should be made to ensure that other sources of energy are found so that when fossil fuel gets depleted the world does not come to a halt. In this regard, many people especially in the U.S. have been concerned with the steps that the government is taking towards encouraging development of other sources of energy.

Consequently, the government has been urged to reduce restrictions impeding the development of renewable sources of energy and increase funding of the same. However, to address this issue, it is better to understand some of the sources renewable energy.

Among the proposed sources of power to be used is solar energy. Solar energy is a renewable source of energy because the sun has been there and can only be absent for a very short period of time. On the same note, harnessing of solar energy is noise proof which means that noise pollution is avoided when using solar power (Boxwell 58).

Similarly, solar power is environmental friendly because it does not produce any form of pollution. In addition, equipments used in the production of solar power are cheap to maintain thus the long run cost of production is low. Moreover, it is easy and cheap to install appliances of solar power.

Similarly, the electricity produced from solar energy can be used to power virtually every thing that uses power (Boxwell 59). It is also important to note that the production of solar power does not lead to environmental degradation like digging up the ground or deforestation.

However, solar power has its disadvantages. To begin with, some people have argued that the initial cost of installing solar power harnessing equipment is very high. Additionally, harnessing of solar power is affected by whether and cannot be done during cloudy or rainy days and at night. Therefore, another source of energy is needed to act as a back up (Boxwell 60).

On the other hand, wind energy is also another source of energy that can replace fossil fuel. Wind energy does not emit green house gases which are dangerous to the environment. Furthermore, no fossil fuels are burnt to produce wind energy thus it does not pollute the environment (Miller and Scott 407). Besides, extraction of wind energy is more efficient given the advancement in technology.

The turbines used to produce wind power only occupy little space at the base leaving room for other activities to be done on the ground. Moreover, wind energy is highly applicable in under developed parts of a country and can add to the tax base of the area.

In addition, renewable sources of energy, wind being among them, require minimal subsidies to maintain. On the same note, the cost of producing wind power is constant and therefore prices for wind power do not fluctuate. Most importantly, wind is free and thus cost of producing wind power is low in the long run (Miller and Scott 407).

It is crucial, however, to highlight that wind power has its share of disadvantages. Firstly, wind power depends on the flow of wind. On the days when the weather is calm wind power might not be generated. On the same note, the initial cost of producing wind power is quite high and individuals may not afford it (Miller and Scott 408). Lastly, power produced by the turbines is insufficient compared to power produced by fossil fuels.

Despite the disadvantages of wind and solar power, their advantages are definitely more. They are renewable and therefore they will never get depleted. Sooner or later the government will have to find alternative ways of producing power.

Consequently, it is high time that the government increased its financial support in the production of the two types of power (Miller and Scott 407). Reduction of restrictions is necessary but it might not be sufficient given the heavy initial cost. Similarly, renewable sources of energy, especially wind and solar power, are both economically and environmentally viable in the long run hence the need to invest in them.

The fact that the country currently satisfies most of its energy requirements should not blind our eyes. We will need to think of how we will operate in future. The fossil fuel that forms the giant part of energy source will definitely be exhausted with time.

It will be a great disservice to the future generations if we do not find sustainable energy sources. Consequently, the government has no option but to encourage the production wind and solar energy.

Renewable Energy

Renewable energy comes from sources that will not be used up in our lifetimes, such as the sun and wind.

The wind, the sun, and Earth are sources of  renewable energy . These energy sources naturally renew, or replenish themselves.

Wind, sunlight, and the planet have energy that transforms in ways we can see and feel. We can see and feel evidence of the transfer of energy from the sun to Earth in the sunlight shining on the ground and the warmth we feel when sunlight shines on our skin. We can see and feel evidence of the transfer of energy in wind’s ability to pull kites higher into the sky and shake the leaves on trees. We can see and feel evidence of the transfer of energy in the geothermal energy of steam vents and geysers .

People have created different ways to capture the energy from these renewable sources.

Solar Energy

Solar energy can be captured “actively” or “passively.”

Active solar energy uses special technology to capture the sun’s rays. The two main types of equipment are photovoltaic cells (also called PV cells or solar cells) and mirrors that focus sunlight in a specific spot. These active solar technologies use sunlight to generate electricity , which we use to power lights, heating systems, computers, and televisions.

Passive solar energy does not use any equipment. Instead, it gets energy from the way sunlight naturally changes throughout the day. For example, people can build houses so their windows face the path of the sun. This means the house will get more heat from the sun. It will take less energy from other sources to heat the house.

Other examples of passive solar technology are green roofs , cool roofs, and radiant barriers . Green roofs are completely covered with plants. Plants can get rid of pollutants in rainwater and air. They help make the local environment cleaner.

Cool roofs are painted white to better reflect sunlight. Radiant barriers are made of a reflective covering, such as aluminum. They both reflect the sun’s heat instead of absorbing it. All these types of roofs help lower the amount of energy needed to cool the building.

Advantages and Disadvantages There are many advantages to using solar energy. PV cells last for a long time, about 20 years.

However, there are reasons why solar power cannot be used as the only power source in a community. It can be expensive to install PV cells or build a building using passive solar technology.

Sunshine can also be hard to predict. It can be blocked by clouds, and the sun doesn’t shine at night. Different parts of Earth receive different amounts of sunlight based on location, the time of year, and the time of day.

Wind Energy

People have been harnessing the wind’s energy for a long, long time. Five-thousand years ago, ancient Egyptians made boats powered by the wind. In 200 B.C.E., people used windmills to grind grain in the Middle East and pump water in China.

Today, we capture the wind’s energy with wind turbines . A turbine is similar to a windmill; it has a very tall tower with two or three propeller-like blades at the top. These blades are turned by the wind. The blades turn a generator (located inside the tower), which creates electricity.

Groups of wind turbines are known as wind farms . Wind farms can be found near farmland, in narrow mountain passes, and even in the ocean, where there are steadier and stronger winds. Wind turbines anchored in the ocean are called “ offshore wind farms.”

Wind farms create electricity for nearby homes, schools, and other buildings.

Advantages and Disadvantages Wind energy can be very efficient . In places like the Midwest in the United States and along coasts, steady winds can provide cheap, reliable electricity.

Another great advantage of wind power is that it is a “clean” form of energy. Wind turbines do not burn fuel or emit any pollutants into the air.

Wind is not always a steady source of energy, however. Wind speed changes constantly, depending on the time of day, weather , and geographic location. Currently, it cannot be used to provide electricity for all our power needs.

Wind turbines can also be dangerous for bats and birds. These animals cannot always judge how fast the blades are moving and crash into them.

Geothermal Energy

Deep beneath the surface is Earth’s core . The center of Earth is extremely hot—thought to be over 6,000 °C (about 10,800 °F). The heat is constantly moving toward the surface.

We can see some of Earth’s heat when it bubbles to the surface. Geothermal energy can melt underground rocks into magma and cause the magma to bubble to the surface as lava . Geothermal energy can also heat underground sources of water and force it to spew out from the surface. This stream of water is called a geyser.

However, most of Earth’s heat stays underground and makes its way out very, very slowly.

We can access underground geothermal heat in different ways. One way of using geothermal energy is with “geothermal heat pumps.” A pipe of water loops between a building and holes dug deep underground. The water is warmed by the geothermal energy underground and brings the warmth aboveground to the building. Geothermal heat pumps can be used to heat houses, sidewalks, and even parking lots.

Another way to use geothermal energy is with steam. In some areas of the world, there is underground steam that naturally rises to the surface. The steam can be piped straight to a power plant. However, in other parts of the world, the ground is dry. Water must be injected underground to create steam. When the steam comes to the surface, it is used to turn a generator and create electricity.

In Iceland, there are large reservoirs of underground water. Almost 90 percent of people in Iceland use geothermal as an energy source to heat their homes and businesses.

Advantages and Disadvantages An advantage of geothermal energy is that it is clean. It does not require any fuel or emit any harmful pollutants into the air.

Geothermal energy is only avaiable in certain parts of the world. Another disadvantage of using geothermal energy is that in areas of the world where there is only dry heat underground, large quantities of freshwater are used to make steam. There may not be a lot of freshwater. People need water for drinking, cooking, and bathing.

Biomass Energy

Biomass is any material that comes from plants or microorganisms that were recently living. Plants create energy from the sun through photosynthesis . This energy is stored in the plants even after they die.

Trees, branches, scraps of bark, and recycled paper are common sources of biomass energy. Manure, garbage, and crops , such as corn, soy, and sugar cane, can also be used as biomass feedstocks .

We get energy from biomass by burning it. Wood chips, manure, and garbage are dried out and compressed into squares called “briquettes.” These briquettes are so dry that they do not absorb water. They can be stored and burned to create heat or generate electricity.

Biomass can also be converted into biofuel . Biofuels are mixed with regular gasoline and can be used to power cars and trucks. Biofuels release less harmful pollutants than pure gasoline.

Advantages and Disadvantages A major advantage of biomass is that it can be stored and then used when it is needed.

Growing crops for biofuels, however, requires large amounts of land and pesticides . Land could be used for food instead of biofuels. Some pesticides could pollute the air and water.

Biomass energy can also be a nonrenewable energy source. Biomass energy relies on biomass feedstocks—plants that are processed and burned to create electricity. Biomass feedstocks can include crops, such as corn or soy, as well as wood. If people do not replant biomass feedstocks as fast as they use them, biomass energy becomes a non-renewable energy source.

Hydroelectric Energy

Hydroelectric energy is made by flowing water. Most hydroelectric power plants are located on large dams , which control the flow of a river.

Dams block the river and create an artificial lake, or reservoir. A controlled amount of water is forced through tunnels in the dam. As water flows through the tunnels, it turns huge turbines and generates electricity.

Advantages and Disadvantages Hydroelectric energy is fairly inexpensive to harness. Dams do not need to be complex, and the resources to build them are not difficult to obtain. Rivers flow all over the world, so the energy source is available to millions of people.

Hydroelectric energy is also fairly reliable. Engineers control the flow of water through the dam, so the flow does not depend on the weather (the way solar and wind energies do).

However, hydroelectric power plants are damaging to the environment. When a river is dammed, it creates a large lake behind the dam. This lake (sometimes called a reservoir) drowns the original river habitat deep underwater. Sometimes, people build dams that can drown entire towns underwater. The people who live in the town or village must move to a new area.

Hydroelectric power plants don’t work for a very long time: Some can only supply power for 20 or 30 years. Silt , or dirt from a riverbed, builds up behind the dam and slows the flow of water.

Other Renewable Energy Sources

Scientists and engineers are constantly working to harness other renewable energy sources. Three of the most promising are tidal energy , wave energy , and algal (or algae) fuel.

Tidal energy harnesses the power of ocean tides to generate electricity. Some tidal energy projects use the moving tides to turn the blades of a turbine. Other projects use small dams to continually fill reservoirs at high tide and slowly release the water (and turn turbines) at low tide.

Wave energy harnesses waves from the ocean, lakes, or rivers. Some wave energy projects use the same equipment that tidal energy projects do—dams and standing turbines. Other wave energy projects float directly on waves. The water’s constant movement over and through these floating pieces of equipment turns turbines and creates electricity.

Algal fuel is a type of biomass energy that uses the unique chemicals in seaweed to create a clean and renewable biofuel. Algal fuel does not need the acres of cropland that other biofuel feedstocks do.

Renewable Nations

These nations (or groups of nations) produce the most energy using renewable resources. Many of them are also the leading producers of nonrenewable energy: China, European Union, United States, Brazil, and Canada

• Alternative Sources of Energy

Introduction to the World of Energy

Sources of energy are very important and we perform different day-to-day tasks with the help of energy. Can you imagine your life without sources of energy? It will be very difficult to survive and life will end. But from where is this energy obtained? Are these sources man-made or natural? Have you ever heard about the alternative sources of energy that are used other than the traditional sources of energy? Let’s discuss these.

People started looking for other energy sources in the late 1900s so they could heat their homes, light their homes, and power their vehicles. People worried that sources like coal, oil, and nuclear power were depleting. Waterpower, wind power, and solar power are examples of alternative energy sources. These and other non-depletable energy sources are referred to as green or renewable.

What are Alternative Sources of Energy? 

Alternative sources of energy can be defined as the use of sources of energy other than the traditional fossil fuels (such as oil, coal, and natural gas), which are shorter in supply and which are considered harmful to the environment. It includes all renewable and nuclear energy sources. 

The most commonly used alternative sources of energy include the following:

Wind Energy

Solar Energy

Geothermal Energy

Hydroelectric Energy

Hydrogen Energy

Nuclear Energy

Tidal Energy

The above-listed sources of energy are explained below:

Uses of Alternative Sources of Energy

1. wind energy.

In this source of energy, the wind is used for producing electricity by making use of the kinetic energy created by air in motion.

2. Solar Energy

In this source of energy, the radiation from the Sun is used which is capable of producing heat, causing chemical reactions, and generating electricity.

3. Geothermal Energy

It is a source of energy that is taken from the Earth’s core. It comes from the heat which is generated during the original formation of the planet.

4. Bioenergy

In this source of energy electricity and gas are generated from the organic matter known as biomass. Bioenergy is one of the resources available to help meet the demand for energy, it includes electricity, heat and transportation fuel. 

5. Hydroelectric Energy

It is a source of energy that is obtained by falling water from high potential to low potential as potential is defined to flow down from a certain height. It is a form of energy that harnesses the power of water in motion—such as water flowing over a waterfall—to generate electricity.

Importance of Alternative Sources of Energy

The importance of alternative sources of energy are discussed below:

Protects the Environment: Alternative sources of energy help to protect the environment and give it the opportunity to regenerate.

Helps in Providing Sustainable Fuel Systems: The alternative sources of energy can help in creating a sustainable fuel system and can help in sustaining the ecological balance of a region.

Helps in Reducing the Dependence on Imported Fuels: Another use of alternate sources of energy is that it helps to reduce the dependence on imported fuels.

Helps in Enhancing Income: It helps in enhancing the income of the country by creating additional employment opportunities for the population of the country.

Useful in Conserving Fossil Fuels: When we make use of alternate sources of energy it helps us in conserving fossil fuels.

Useful in Slowing and Reversing Climate Change: Because the alternate sources of energy have a much lower carbon content it helps to slow down and reverse climate change.

Useful in Economic Growth: Producing more utility-scale energy systems can help in creating more economic growth.

Thus it can conclude that the alternate sources of energy are the future energy sources that will help in sustaining the environment as well as help in minimising the dependency on conventional energy sources. These sources of energy need to be explored more and more.

FAQs on Alternative Sources of Energy

1. What percentage of the world uses alternate sources of energy and which is the most widely used alternate source of energy?

From 27% in 2019 the share of renewables in global electricity increased to 29% in 2020. The increase in alternative sources of energy mainly came at the cost of gas and coal, though these two sources still represent close to 60% of the global electricity supply. The most widely used alternate source of energy in the world is hydropower energy. Before lockdown, some measures were implemented, and shares of renewables were higher due to favourable weather conditions. The global use of alternate sources of energy was 1.5% higher in 2020 than in 2019.

2. Why are we looking at alternate sources of energy?

We are looking at alternative sources of energy because as our standards of living are increasing day by day so are our energy requirements. So a need has arisen to exploit and look for more and more alternative sources of energy. Another reason why we are looking for alternate sources of energy is that our conventional sources of energy like fossil fuels get depleted very soon which is why we need to look for other alternatives as well.

3. Write some interesting facts about alternative sources of energy.

Some interesting facts about alternative sources of energy are given below:

There are over two million solar power systems installed in the United States.

The alternate sources of energy create five times more employment opportunities than the conventional sources of energy.

Solar energy is nearly 200 years old.

One wind turbine can be used to power nearly 1500 homes for a year.

This Is the Future: Essay on Renewable Energy

Today the world population depends on nonrenewable energy resources. With the constantly growing demand for energy, natural gas, coal, and oil get used up and cannot replenish themselves. 

Aside from limited supply, heavy reliance on fossil fuels causes planetary-scale damage. Sea levels are rising. Heat-trapping carbon dioxide increased the warming effect by 45% from 1990 to 2019. The only way to tackle the crisis is to start the transition to renewable energy now. 

What is renewable energy? It is energy that comes from replenishable natural resources like sunlight, wind, thermal energy, moving water, and organic materials. Renewable resources do not run out. They are cost-efficient and renew faster than they are consumed. How does renewable energy save money? It creates new jobs, supports economic growth, and decreases inequitable fossil fuel subsidies. 

At the current rates of production, some fossil fuels will not even last another century. This is why the future depends on reliable and eco-friendly resources. This renewable energy essay examines the types and benefits of renewable energy and its role in creating a sustainable future.

Top 5 Types of Renewable Energy: The Apollo Alliance Rankings

There are many natural resources that can provide people with clean energy. To make a list of the five most booming types of renewable energy on the market today, this energy essay uses data gathered by the Apollo Alliance. It is a project that aims to revolutionize the energy sector of the US with a focus on clean energy. 

The Apollo Alliance unites businesses, community leaders, and environmental experts to support the transition to more sustainable and efficient living. Their expert opinion helped to compile information about the most common and cost-competitive sources of renewable energy. However, if you want to get some more in-depth research, you can entrust it to an essay writer . Here’s a quick overview of renewable energy resources that have a huge potential to substitute fossil fuels. 

Solar Renewable Energy

The most abundant and practically endless resource is solar energy. It can be turned into electricity by photovoltaic systems that convert radiant energy captured from sunlight. Solar farms could generate enough energy for thousands of homes.

An endless supply is the main benefit of solar energy. The rate at which the Earth receives it is 10,000 times greater than people can consume it, as a paper writer points out based on their analysis of research findings. It can substitute fossil fuels and deliver people electricity, hot water, cooling, heat, etc. 

The upfront investment in solar systems is rather expensive. This is one of the primary limitations that prevent businesses and households from switching to this energy source at once. However, the conclusion of solar energy is still favorable. In the long run, it can significantly decrease energy costs. Besides, solar panels are gradually becoming more affordable to manufacture and adopt, even at an individual level. 

Wind Renewable Energy

Another clean energy source is wind. Wind farms use the kinetic energy of wind flow to convert it into electricity. The Appolo Alliance notes that, unlike solar farms, they can’t be placed in any location. To stay cost-competitive, wind farms should operate in windy areas. Although not all countries have the right conditions to use them on a large scale, wind farms might be introduced for some energy diversity. The technical potential for it is still tremendous. 

Wind energy is clean and safe for the environment. It does not pollute the atmosphere with any harmful products compared to nonrenewable energy resources. 

The investment in wind energy is also economically wise. If you examine the cost of this energy resource in an essay on renewable resources, you’ll see that wind farms can deliver electricity at a price lower than nonrenewable resources. Besides, since wind isn’t limited, its cost won’t be influenced by the imbalance of supply and demand.

Geothermal Renewable Energy

Natural renewable resources are all around us, even beneath the ground. Geothermal energy can be produced from the thermal energy from the Earth’s interior. Sometimes heat reaches the surface naturally, for example, in the form of geysers. But it can also be used by geothermal power plants. The Earth’s heat gets captured and converted to steam that turns a turbine. As a result, we get geothermal energy.

This source provides a significant energy supply while having low emissions and no significant footprint on land. A factsheet and essay on renewable resources state that geothermal plants will increase electricity production from 17 billion kWh in 2020 to 49.8 billion kWh in 2050.

However, this method is not without limitations. While writing a renewable resources essay, consider that geothermal energy can be accessed only in certain regions. Geological hotspots are off-limits as they are vulnerable to earthquakes. Yet, the quantity of geothermal resources is likely to grow as technology advances. 

Ocean Renewable Energy

The kinetic and thermal energy of the ocean is a robust resource. Ocean power systems rely on:

• Changes in sea level;
• Wave energy;
• Water surface temperatures;
• The energy released from seawater and freshwater mixing.

Ocean energy is more predictable compared to other resources. As estimated by EPRI, it has the potential to produce 2640 TWh/yr. However, an important point to consider in a renewable energy essay is that the kinetic energy of the ocean varies. Yet, since it is ruled by the moon’s gravity, the resource is plentiful and continues to be attractive for the energy industry. 

Wave energy systems are still developing. The Apollo energy corporation explores many prototypes. It is looking for the most reliable and robust solution that can function in the harsh ocean environment. 

Another limitation of ocean renewable energy is that it may cause disruptions to marine life. Although its emissions are minimal, the system requires large equipment to be installed in the ocean. 

Biomass Renewable Energy

Organic materials like wood and charcoal have been used for heating and lighting for centuries. There are a lot more types of biomass: from trees, cereal straws, and grass to processed waste. All of them can produce bioenergy. 

Biomass can be converted into energy through burning or using methane produced during the natural process of decomposition. In an essay on renewable sources of energy, the opponents of the method point out that biomass energy is associated with carbon dioxide emissions. Yet, the amount of released greenhouse gases is much lower compared to nonrenewable energy use. 

While biomass is a reliable source of energy, it is only suitable for limited applications. If used too extensively, it might lead to disruptions in biodiversity, a negative impact on land use, and deforestation. Still, Apollo energy includes biomass resources that become waste and decompose quickly anyway. These are organic materials like sawdust, chips from sawmills, stems, nut shells, etc. 

What Is the Apollo Alliance?

The Apollo Alliance is a coalition of business leaders, environmental organizations, labor unions, and foundations. They all unite their efforts in a single project to harness clean energy in new, innovative ways. 

Why Apollo? Similarly to President John F. Kennedy’s Apollo Project, Apollo energy is a strong visionary initiative. It is a dare, a challenge. The alliance calls for the integrity of science, research, technology, and the public to revolutionize the energy industry.

The project has a profound message. Apollo energy solutions are not only about the environment or energy. They are about building a new economy. The alliance gives hope to building a secure future for Americans. 

What is the mission of the Apollo Alliance? 

• Achieve energy independence with efficient and limitless resources of renewable energy.
• Pioneer innovation in the energy sector.
• Build education campaigns and communication to inspire new perceptions of energy. 
• Create new jobs.
• Reduce dependence on imported fossil fuels. 
• Build healthier and happier communities. 

The transformation of the industry will lead to planet-scale changes. The Apollo energy corporation can respond to the global environmental crisis and prevent climate change. 

Apollo renewable energy also has the potential to become a catalyst for social change. With more affordable energy and new jobs in the industry, people can bridge the inequality divide and build stronger communities. 

Why Renewable Energy Is Important for the Future

Renewable energy resources have an enormous potential to cover people’s energy needs on a global scale. Unlike fossil fuels, they are available in abundance and generate minimal to no emissions. 

The burning of fossil fuels caused a lot of environmental problems—from carbon dioxide emissions to ocean acidification. Research this issue in more detail with academic assistance from essay writer online . You can use it to write an essay on renewable sources of energy to explain the importance of change and its global impact. 

Despite all the damage people caused to the planet, there’s still hope to mitigate further repercussions. Every renewable energy essay adds to the existing body of knowledge we have today and advances research in the field. Here are the key advantages and disadvantages of alternative energy resources people should keep in mind. 

Advantage of Green Energy

The use of renewable energy resources has a number of benefits for the climate, human well-being, and economy:

• Renewable energy resources have little to no greenhouse gas emissions. Even if we take into account the manufacturing and recycling of the technologies involved, their impact on the environment is significantly lower compared to fossil fuels. 
• Renewable energy promotes self-sufficiency and reduces a country’s dependence on foreign fuel. According to a study, a 1% increase in the use of renewable energy increases economic growth by 0.21%. This gives socio-economic stability.
• Due to a lack of supply of fossil fuels and quick depletion of natural resources, prices for nonrenewable energy keep increasing. In contrast, green energy is limitless and can be produced locally. In the long run, this allows decreasing the cost of energy. 
• Unlike fossil fuels, renewable energy doesn’t emit air pollutants. This positively influences health and quality of life. 
• The emergence of green energy plants creates new jobs. Thus, Apollo energy solutions support the growth of local communities. By 2030, the transition to renewable energy is expected to generate 10.3 million new jobs. 
• Renewable energy allows decentralization of the industry. Communities get their independent sources of energy that are more flexible in terms of distribution. 
• Renewable energy supports equality. It has the potential to make energy more affordable to low-income countries and expand access to energy even in remote and less fortunate neighborhoods. 

Disadvantages of Non-Conventional Energy Sources

No technology is perfect. Renewable energy resources have certain drawbacks too: 

• The production of renewable energy depends on weather conditions. For example, wind farms could be effective only in certain locations where the weather conditions allow it. The weather also makes it so that renewable energy cannot be generated around the clock. 
• The initial cost of renewable energy technology is expensive. Both manufacturing and installation require significant investment. This is another disadvantage of renewable resources. It makes them unaffordable to a lot of businesses and unavailable for widespread individual use. In addition, the return on investment might not be immediate.
• Renewable energy technology takes up a lot of space. It may affect life in the communities where these clean energy farms are installed. They may also cause disruptions to wildlife in the areas. 
• One more limitation a renewable resources essay should consider is the current state of technology. While the potential of renewable energy resources is tremendous, the technology is still in its development phase. Therefore, renewable energy might not substitute fossil fuels overnight. There’s a need for more research, investment, and time to transition to renewable energy completely. Yet, some diversity of energy resources should be introduced as soon as possible. 
• Renewable energy resources have limited emissions, but they are not entirely pollution-free. The manufacturing process of equipment is associated with greenhouse gas emissions while, for example, the lifespan of a wind turbine is only 20 years. 

For high school seniors eyeing a future rich with innovative endeavors in renewable energy or other fields, it's crucial to seek financial support early on. Explore the top 10 scholarships for high school seniors to find the right fit that can propel you into a future where you can contribute to the renewable energy movement and beyond.

Short Essay on Renewable Energy (200 – 250 Words)

Renewable energy is produced from the resources that are available in nature. Energy can be easily produced from renewable resources that are available free of cost. We can use renewable energy without the fear of its running out. This energy is also called as ‘green energy’ and ‘clean energy’.

Some renewable energy is solar energy, hydro energy, wind energy, geothermal energy, and biomass energy. Today we are mostly dependent on non-renewable resources like coal, petroleum, etc that will end one day. Also, they are harmful to the environment. Hence, renewable energy is a good alternative for today as well as for tomorrow.

As the name suggests, renewable energy can be easily regenerated. Renewable energy does not produce harmful gases and is hence considered safe for the environment. On seeing the current condition of the environment, renewable energy is the need of an hour.  

However, renewable energy does have a black side. Generally, price is the superior reason that restricts the usage of clean energy in the world. It also requires higher maintenance and installation price. Another disadvantage is the location-centric. Not every type of renewable energy is produced everywhere. A particular atmosphere is required to produce renewable energy.

On noticing the consequences of non-renewable energy, indeed, the future can only be safe if we use renewable energy.

Long Essay on Renewable Energy (500 – 600 Words)

Introduction

Electricity is a secondary form of energy. It is produced from different sources of energy. Energy can be renewable or non-renewable. Renewable energy can be renewed or re-generated easily but the non-renewable resources are limited on the earth. They can’t be generated again. Therefore, renewable energy is much better than non-renewable energy.

Sources of Renewable Energy

There are five major sources responsible for generating renewable energy. They are:

• Solar energy: Sun is the major source of renewable energy that is termed as solar energy.  The light and heat of the sun are used to produce energy. Solar cookers, solar panels, or solar cells are used to utilize solar energy. Scientists are also preparing to launch solar-powered cars.
• Wind energy: Wind is also used to produce energy. Windmills run using turbines and generators are constructed to generate wind energy. Wind energy is a good contributor to global energy demand.
• Biomass energy: Wastes from plants and animals are used to produce energy, which we call biomass energy. Biomass is an eco-friendly method of energy production. Different methods are used to produce biomass energy from biofuels.
• Geothermal energy: Geothermal energy is produced from the heat below the earth’s surface. This energy can be used to produce electricity, heat buildings, bathing, etc.
• Hydropower energy: The force of water is used to produce energy and is referred to as hydropower energy. Hydropower is more reliable than other renewable sources. The construction of reservoirs, canals, dams, etc helps to control the flow of water which is later, used to run turbines to produce electricity.

Advantages of Renewable Energy

The primary advantage of renewable energy is that it can be renewed easily. It is the only option that will meet the energy requirement of today as well as tomorrow. Unlike fossil fuels that are limited on the earth, we can use renewable energy for a lifetime. Renewable energy is good for both humans and the environment. Non-renewable energy like fossil fuels causes pollution and environmental hazards like acid rain, global warming, etc. The amount of carbon emissions from renewable energy is much low than those of non-renewable energy.

Therefore, depending on renewable energy will save us from this serious issue. Renewable energy is the most reliable form of energy and we can also say that it is the future of the world’s energy needs.

Disadvantages of Renewable Energy

We all know the importance and benefits of renewable energy but there are some limitations to its usage. The main disadvantage is the cost. The cost of generating energy from renewable resources is very high when compared to that of non-renewable sources. People find burning coal cheaper and easier than installing a solar panel.

Most of the renewable resources depend on natural sources that can be obtained in a particular location. For example, solar energy cannot be fruitful for cold locations or geothermal energy can only be obtained in a location where fast-flowing water resources are available. This limits the use of renewable resources to a great extent. However, they cannot be considered fully safe for living things and the environment. The hydroelectricity project has an adverse effect on aquatic life and the ecosystem.

The increasing population demands an increase in energy consumption. Energy is necessary for home, business, and almost every work. Thanks to innovation and invention that helps in utilizing renewable resources and maintaining a sustainable level of energy in the world.

I hope the above provided essay on renewable energy is easy to understand. We should use energy efficiently to live a healthy and peaceful life.

Energy security and food security are two of the indispensable issues of human life. Thus, these issues are viewed as the most important topics of today’s world. Strategically, three essential elements of human life are food, water and energy. These elements have also vital importance for the economic development of a country. Political problems and even great wars between countries mainly arise from the need to satisfy these three needs. Energy is very crucial not only for an economy in well-condition and sustainable economic growth, but also for a sustainable agricultural production. Fossil fuels are mainly benefited in agriculture for tillage, irrigation, production and using of fertilizers, agro-process, and transportation. On the other hand, renewable energy resources; such as, solar energy, wind energy, bio-fuels and geothermal energy are used partially in the various fields of agricultural production. In this study, the relationship between energy resources and agricultural production will be studied in depth. The current situation of Turkey’s agricultural production with respect to these energy resources, and how the country is being affected from these techniques of production are also going to be displayed.

This is the age of renewable energy technology. Gone are the days, when conventional energy sources were given significance. These sources include coal, oil and natural gas. They are a major cause of air pollution. Moreover, they will end up one day and hence cannot be relied upon. Due to these large amount of demerits, the usage of conventional (non renewable) fossils fuels is being discontinued. They are being gradually replaced by renewable sources of energy such as solar, wind, hydro and biomass. When it comes to selection between wind and solar energy, many important factors need to be considered. This paper briefly presents merits and demerits of both types of sources along with their challenges.

Alternative energy, simply means energy that is produced from sources other than our primary energy supply: fossil fuels. Coal, oil and natural gas are the three kinds of fossil fuels that we have mostly depended on for our energy needs, from home heating and electricity to fuel for our industries, automobiles and mass transportation. The fossil fuels are of non-renewable nature. They are limited in supply and will one day they will be depleted. There is no escape from this conclusion. Fossil fuels formed from plants and animals that lived hundreds of millions of years ago and became buried underneath the Earth's surface where their remains collectively transformed into the combustible materials that we use for fuel. In fact, the earliest known fossil fuel deposits are from the Cambrian Period about 500 million years ago, way before the dinosaurs emerged onto the scene. This is when most of the major groups of animals first appeared on Earth. The later fossil fuels which provide more substandard fuels like peat or lignite coal (soft coal) began forming as late as five million years ago in the Pliocene Period. There is no doubt that at our current rate of consumption, these fuels cannot occur fast enough to meet our current or future energy demands. Fossil fuel, along with nuclear energy a controversial, non-renewable energy source is supplying 93% of the world's energy resources. The rest, 7% of the world's energy needs, are supplied by alternative energy sources — more appropriately called renewables. Every day, the world produces carbon dioxide by using of fossil fuels that is released to the earth's atmosphere and which will still be there in next one hundred years time. This increased content of Carbon Dioxide increases the warmth of our planet and is the main cause of the so called " Global Warming M.R. KOLHE and Dr. P.G. KHOT http://www.iaeme.com/IJM/index.asp 30 [email protected] Effect ". One answer to global warming is to replace and retrofit current technologies with alternatives that have comparable or better performance, but do not emit carbon dioxide. We call this Alternative energy. It is expected that by 2050, one-third of the world's energy will need to come from solar, wind, and other renewable resources. Climate change, population growth, and fossil fuel depletion mean that renewables will need to play a bigger role in the future than they do today. Alternative energy refers to energy sources that have no undesired consequences such for example fossil fuels or nuclear energy. Alternative energy sources are renewable and are thought to be "free" energy sources. They all have lower carbon emissions, compared to conventional energy sources. These include Biomass Energy, Wind Energy, Solar Energy, Geothermal Energy, Hydroelectric Energy sources. Combined with the use of recycling, the use of clean alternative energies such as the home use of solar power systems will help ensure man's survival into the 21st century and beyond. In this paper, the stress has been given on the future of fossil fuel which are at diminishing stage and their replacement by renewable energy sources and their limitations.

An ever growing population means an ever growing requirement for energy. Nowadays, enormity of energy cannot be denied. It is essential in every walk of life. Energy sources can be broadly classified as renewable and non renewable. Knowing the dreadful fact that nonrenewable sources will eventually deplete, the importance of renewable sources cannot be underestimated. The most important aspect while utilizing them is their impact on the environment. This paper briefly presents the importance of renewable sources of energy owing to the backdrop of fossil fuel dilemma. Major emphasis is placed on the use of alternative energy technologies. Some applications of renewable sources and future of energy is also discussed.

In the present study we analyzed the effect of ascorbate (0.8 mM)/Fe2+ (2.5 μM)-induced membrane lipid peroxidation on the levels of intracellular free calcium, [Ca2+]i, and on the possible mechanisms involved in the perturbation of intracellular calcium homeostasis during oxidative stress. For this purpose, the influence of the ascorbate/iron oxidant system on the plasma membrane and endoplasmic reticulum Ca2+-dependent ATPases of brain cortical synaptosomes was studied. In addition, the influence of the peroxidative process on the uptake of calcium (45Ca2+) and on the Na+/Ca2+ exchange activity at the plasma membrane was evaluated. After ascorbate/Fe2+-induced membrane lipid peroxidation of the order of 18.05 ± 4.20 nmol TBARS/mg protein, an increase in [Ca2+]i occured, under basal or depolarizing conditions (30 mM KCI), which was dependent on the extracellular calcium concentration. Thus, for 1 and 3 mM extracellular calcium concentration, an increase of the resting [Ca2+]i values of 19.8% and 33.7% was observed, while after the K+-depolarization the enhancement of the [Ca2+]i was 18.4% and 29.5%, respectively. The Na+/Ca2+ exchange activity and the time-dependent influx of 45 Ca2+, observed in basal conditions and after the 30 mM K+-depolarization, were not affected under the peroxidative conditions. The Ca2+-dependent ATPase activity of the synaptosomal plasma membrane was significantly depressed following peroxidation of membrane lipids, decreasing the Vmax by 48.1%, without significant changes in the affinity of the enzyme for calcium (Km for Ca2+ was 0.54 ± 0.04 μM in control conditions and 0.56 ± 0.034 μM in peroxidized conditions). The Ca 2+-ATPase activity of the endoplasmic reticulum was also affected during ascorbate/iron-induced oxidative stress; thus, an inhibition of 45.2% was observed 5 min after adding ATP. These data suggest that the increase in synaptosomal [Ca2+]i due to oxidative stress may result from the inhibition of the plasma membrane and the endoplasmic reticulum membrane Ca2+-ATPase activities, probably as a result of the alteration of the lipid environment required for the maximal activity of these membrane enzymes. The consequent increase in [Ca2+]i may be responsible for the injury of the nervous tissue observed during several pathological conditions in which free radical generation seems to be involved.

Essay on Sources of Energy

Students are often asked to write an essay on Sources of Energy in their schools and colleges. And if you’re also looking for the same, we have created 100-word, 250-word, and 500-word essays on the topic.

Let’s take a look…

100 Words Essay on Sources of Energy

Introduction.

Energy is vital for our daily life. It powers our homes, schools, and cities. Energy comes from different sources, mainly classified into two categories: renewable and non-renewable.

Non-Renewable Energy

Non-renewable energy comes from sources that will run out or will not be replenished in our lifetimes. Examples include oil, natural gas, and coal. These sources are often used to generate electricity.

Renewable Energy

Renewable energy is from sources that never run out or are replenished quickly. Sunlight, wind, water, and geothermal heat are examples. These sources are environmentally friendly but require technology to harness.

Understanding energy sources helps us make informed choices. It’s important to support renewable energy for a sustainable future.

250 Words Essay on Sources of Energy

Energy is the driving force behind all natural and artificial phenomena. It is an indispensable resource in our daily lives, powering our homes, industries, and transportation. The sources of energy can be broadly classified into two categories: renewable and non-renewable.

Non-renewable Energy Sources

Non-renewable energy sources are finite and will eventually deplete. They include fossil fuels such as coal, oil, and natural gas. These energy sources are primarily used for electricity generation and transportation. However, their usage results in harmful environmental impacts, including air pollution and climate change, due to the emission of greenhouse gases.

Renewable Energy Sources

Renewable energy sources, on the other hand, are inexhaustible and can be replenished naturally. They include solar, wind, hydro, geothermal, and biomass energy. Solar energy, harnessed through photovoltaic cells, is a clean and abundant source. Wind energy, captured by wind turbines, is another potent source, especially in coastal and high-altitude regions.

Hydro energy, derived from the kinetic energy of flowing or falling water, is a dominant renewable source, while geothermal energy, obtained from the Earth’s internal heat, is reliable and consistent. Biomass energy, generated from organic materials, can be a sustainable option if managed responsibly.

The transition from non-renewable to renewable energy sources is crucial for sustainable development. While non-renewable sources have been the backbone of our energy infrastructure, their environmental impacts necessitate a shift towards cleaner, renewable sources. This transition is not only an environmental imperative but also an opportunity for economic growth and energy security.

500 Words Essay on Sources of Energy

Energy is the backbone of all human activities, powering everything from our homes and industries to our transportation systems. The sources of energy we use are diverse and each has its own advantages and disadvantages. They can broadly be classified into two categories: renewable and non-renewable energy sources.

Non-Renewable Energy Sources

Non-renewable energy sources are those that do not replenish in a short time. They include fossil fuels such as coal, oil, and natural gas. These energy sources are formed over millions of years from the remains of plants and animals. They are finite and their extraction and use lead to environmental pollution.

Coal, for instance, is used to generate electricity and in industrial processes requiring heat. Its extraction, however, often leads to environmental degradation and health hazards. Oil is used in transportation and manufacturing, but its extraction can lead to oil spills causing severe environmental damage. Natural gas, although cleaner than coal and oil, is still a major contributor to greenhouse gas emissions.

Renewable energy sources are those that can be replenished naturally in a short time. They include solar, wind, hydro, geothermal, and biomass energy. These sources are considered environmentally friendly as they produce little to no greenhouse gases.

Solar energy harnesses the power of the sun and converts it into electricity. It’s a clean, abundant source of energy, but its efficiency is affected by weather conditions and geographical location. Wind energy converts the kinetic energy of wind into electricity. It’s a clean and renewable source, but its effectiveness is dependent on wind speed and direction.

Hydropower uses the energy of flowing or falling water to generate electricity. It’s renewable and produces a significant amount of electricity, but it can disrupt aquatic ecosystems and requires significant infrastructure. Geothermal energy harnesses the heat from the earth’s crust to generate electricity. It’s a reliable and constant source of energy but its extraction can cause land instability.

Biomass energy comes from organic materials like plant and animal waste. It’s renewable, but its use can lead to deforestation and it produces some greenhouse gases.

The world’s energy needs are diverse and complex. Non-renewable energy sources have been the mainstay of our energy systems, but their environmental impact and finite nature necessitate a shift towards renewable energy sources. However, these too have their challenges. The future of energy therefore lies in a balanced mix of different energy sources, improved energy efficiency, and technological innovations that mitigate the downsides of each source. As we move towards a sustainable future, the understanding and exploration of these energy sources become more crucial than ever.

That’s it! I hope the essay helped you.

Short Article on “Alternative Energy Sources”

The rapid increase in the demand of energy has caused worry about its supply. The main sources of energy are conventional sources. They are non-renewable and exhaustible sources.

Image Courtesy : associatedrenewable.com/images/alternative_energy.jpg

The demand of energy has increased all over the world and the condition poses a threat on the sources of energy like Petroleum and Natural gas by the year 2030-35 if any alternative sources do not substitute or supplement them.

The Government of India gives high priority to the use of alternative, non-conventional and renewable energy sources as supplement to the depleting conventional sources of energy. These alternative sources include – Solar energy, Wind energy, Geo-thermal energy, Tidal energy, Biomass energy etc.

These energy sources have huge potential of energy and they can be useful in various ways.

Solar energy is a wide source. Solar cells, solar cookers, solar ponds etc are the devices to trap solar energy. It can produce electricity, cook food, heat water and can be converted to other forms of energy.

The solar photovoltaic system which uses solar cells to convert the solar energy into electrical energy is the most promising and progressive sources of alternative energy.

Wind energy is in form of Kinetic Energy. A blade of windmill is moved by blowing winds and could be exploited for doing work. Theoretically about 60% of the wind energy can be converted into other forms of energy. Wind mill farms are being set up in the world to exploit this energy at suitable places.

Geothermal energy can be used to produce electricity. However, the inner heat of the Earth not available everywhere which can be commercially exploited. Such potential has been found in Pegu valley in Jammu and Kashmir in India.

Tidal energy associated with the kinetic energy of tides can be converted into electricity by using turbine. In the coastal areas this possibility is available.

Biomass energy is being used in villages but improvement in method and scientific equipments can increase utilisation. It reduces waste materials and gives cheap energy. Jathropa is a plant that produces diesel and it is pollution free. Besides the railways lines, Jathropa planting is in implementation. Hydrogen is also proved to be a great advantageous source of energy.

Nowadays, nuclear energy is gaining utmost importance.

These alternative sources of energy promise a new horizon in sustainable manner.

What the data says about Americans’ views of climate change

A recent report from the United Nations’ Intergovernmental Panel on Climate Change has underscored the need for international action to avoid increasingly severe climate impacts in the years to come. Steps outlined in the report, and by climate experts, include major reductions in greenhouse gas emissions from sectors such as energy production and transportation.

But how do Americans feel about climate change, and what steps do they think the United States should take to address it? Here are eight charts that illustrate Americans’ views on the issue, based on recent Pew Research Center surveys.

Pew Research Center published this collection of survey findings as part of its ongoing work to understand attitudes about climate change and energy issues. The most recent survey was conducted May 30-June 4, 2023, among 10,329 U.S. adults. Earlier findings have been previously published, and methodological information, including the sample sizes and field dates, can be found by following the links in the text.

Everyone who took part in the June 2023 survey is a member of the Center’s American Trends Panel (ATP), an online survey panel that is recruited through national, random sampling of residential addresses. This way, nearly all U.S. adults have a chance of selection. The survey is weighted to be representative of the U.S. adult population by gender, race, ethnicity, partisan affiliation, education and other categories. Read more about the ATP’s methodology .

Here are the questions used for this analysis , along with responses, and its methodology .

A majority of Americans support prioritizing the development of renewable energy sources. Two-thirds of U.S. adults say the country should prioritize developing renewable energy sources, such as wind and solar, over expanding the production of oil, coal and natural gas, according to a survey conducted in June 2023.

In a previous Center survey conducted in 2022, nearly the same share of Americans (69%) favored the U.S. taking steps to become carbon neutral by 2050 , a goal outlined by President Joe Biden at the outset of his administration. Carbon neutrality means releasing no more carbon dioxide into the atmosphere than is removed.

Nine-in-ten Democrats and Democratic-leaning independents say the U.S. should prioritize developing alternative energy sources to address America’s energy supply. Among Republicans and Republican leaners, 42% support developing alternative energy sources, while 58% say the country should prioritize expanding exploration and production of oil, coal and natural gas.

There are important differences by age within the GOP. Two-thirds of Republicans under age 30 (67%) prioritize the development of alternative energy sources. By contrast, 75% of Republicans ages 65 and older prioritize expanding the production of oil, coal and natural gas.

Americans are reluctant to phase out fossil fuels altogether, but younger adults are more open to it. Overall, about three-in-ten adults (31%) say the U.S. should completely phase out oil, coal and natural gas. More than twice as many (68%) say the country should use a mix of energy sources, including fossil fuels and renewables.

While the public is generally reluctant to phase out fossil fuels altogether, younger adults are more supportive of this idea. Among Americans ages 18 to 29, 48% say the U.S. should exclusively use renewables, compared with 52% who say the U.S. should use a mix of energy sources, including fossil fuels.

There are age differences within both political parties on this question. Among Democrats and Democratic leaners, 58% of those ages 18 to 29 favor phasing out fossil fuels entirely, compared with 42% of Democrats 65 and older. Republicans of all age groups back continuing to use a mix of energy sources, including oil, coal and natural gas. However, about three-in-ten (29%) Republicans ages 18 to 29 say the U.S. should phase out fossil fuels altogether, compared with fewer than one-in-ten Republicans 50 and older.

There are multiple potential routes to carbon neutrality in the U.S. All involve major reductions to carbon emissions in sectors such as energy and transportation by increasing the use of things like wind and solar power and electric vehicles. There are also ways to potentially remove carbon from the atmosphere and store it, such as capturing it directly from the air or using trees and algae to facilitate carbon sequestration.

The public supports the federal government incentivizing wind and solar energy production. In many sectors, including energy and transportation, federal incentives and regulations significantly influence investment and development.

Two-thirds of Americans think the federal government should encourage domestic production of wind and solar power. Just 7% say the government should discourage this, while 26% think it should neither encourage nor discourage it.

Views are more mixed on how the federal government should approach other activities that would reduce carbon emissions. On balance, more Americans think the government should encourage than discourage the use of electric vehicles and nuclear power production, though sizable shares say it should not exert an influence either way.

When it comes to oil and gas drilling, Americans’ views are also closely divided: 34% think the government should encourage drilling, while 30% say it should discourage this and 35% say it should do neither. Coal mining is the one activity included in the survey where public sentiment is negative on balance: More say the federal government should discourage than encourage coal mining (39% vs. 21%), while 39% say it should do neither.

Americans see room for multiple actors – including corporations and the federal government – to do more to address the impacts of climate change. Two-thirds of adults say large businesses and corporations are doing too little to reduce the effects of climate change. Far fewer say they are doing about the right amount (21%) or too much (10%).

Majorities also say their state elected officials (58%) and the energy industry (55%) are doing too little to address climate change, according to a March 2023 survey.

In a separate Center survey conducted in June 2023, a similar share of Americans (56%) said the federal government should do more to reduce the effects of global climate change.

When it comes to their own efforts, about half of Americans (51%) think they are doing about the right amount as an individual to help reduce the effects of climate change, according to the March 2023 survey. However, about four-in-ten (43%) say they are doing too little.

Democrats and Republicans have grown further apart over the last decade in their assessments of the threat posed by climate change. Overall, a majority of U.S. adults (54%) describe climate change as a major threat to the country’s well-being. This share is down slightly from 2020 but remains higher than in the early 2010s.

Nearly eight-in-ten Democrats (78%) describe climate change as a major threat to the country’s well-being, up from about six-in-ten (58%) a decade ago. By contrast, about one-in-four Republicans (23%) consider climate change a major threat, a share that’s almost identical to 10 years ago.

Concern over climate change has also risen internationally, as shown by separate Pew Research Center polling across 19 countries in 2022. People in many advanced economies express higher levels of concern than Americans . For instance, 81% of French adults and 73% of Germans describe climate change as a major threat.

Climate change is a lower priority for Americans than other national issues. While a majority of adults view climate change as a major threat, it is a lower priority than issues such as strengthening the economy and reducing health care costs.

Overall, 37% of Americans say addressing climate change should be a top priority for the president and Congress in 2023, and another 34% say it’s an important but lower priority. This ranks climate change 17th out of 21 national issues included in a Center survey from January.

As with views of the threat that climate change poses, there’s a striking contrast between how Republicans and Democrats prioritize the issue. For Democrats, it falls in the top half of priority issues, and 59% call it a top priority. By comparison, among Republicans, it ranks second to last, and just 13% describe it as a top priority.

Our analyses have found that partisan gaps on climate change are often widest on questions – such as this one – that measure the salience or importance of the issue. The gaps are more modest when it comes to some specific climate policies. For example, majorities of Republicans and Democrats alike say they would favor a proposal to provide a tax credit to businesses for developing technologies for carbon capture and storage.

Perceptions of local climate impacts vary by Americans’ political affiliation and whether they believe that climate change is a serious problem. A majority of Americans (61%) say that global climate change is affecting their local community either a great deal or some. About four-in-ten (39%) see little or no impact in their own community.

The perception that the effects of climate change are happening close to home is one factor that could drive public concern and calls for action on the issue. But perceptions are tied more strongly to people’s beliefs about climate change – and their partisan affiliation – than to local conditions.

For example, Americans living in the Pacific region – California, Washington, Oregon, Hawaii and Alaska – are more likely than those in other areas of the country to say that climate change is having a great deal of impact locally. But only Democrats in the Pacific region are more likely to say they are seeing effects of climate change where they live. Republicans in this region are no more likely than Republicans in other areas to say that climate change is affecting their local community.

Our previous surveys show that nearly all Democrats believe climate change is at least a somewhat serious problem, and a large majority believe that humans play a role in it. Republicans are much less likely to hold these beliefs, but views within the GOP do vary significantly by age and ideology. Younger Republicans and those who describe their views as moderate or liberal are much more likely than older and more conservative Republicans to describe climate change as at least a somewhat serious problem and to say human activity plays a role.

Democrats are also more likely than Republicans to report experiencing extreme weather events in their area over the past year – such as intense storms and floods, long periods of hot weather or droughts – and to see these events as connected with climate change.

About three-quarters of Americans support U.S. participation in international efforts to reduce the effects of climate change. Americans offer broad support for international engagement on climate change: 74% say they support U.S. participation in international efforts to reduce the effects of climate change.

Still, there’s little consensus on how current U.S. efforts stack up against those of other large economies. About one-in-three Americans (36%) think the U.S. is doing more than other large economies to reduce the effects of global climate change, while 30% say the U.S. is doing less than other large economies and 32% think it is doing about as much as others. The U.S. is the second-largest carbon dioxide emitter , contributing about 13.5% of the global total.

When asked what they think the right balance of responsibility is, a majority of Americans (56%) say the U.S. should do about as much as other large economies to reduce the effects of climate change, while 27% think it should do more than others.

A previous Center survey found that while Americans favor international cooperation on climate change in general terms, their support has its limits. In January 2022 , 59% of Americans said that the U.S. does not have a responsibility to provide financial assistance to developing countries to help them build renewable energy sources.

In recent years, the UN conference on climate change has grappled with how wealthier nations should assist developing countries in dealing with climate change. The most recent convening in fall 2022, known as COP27, established a “loss and damage” fund for vulnerable countries impacted by climate change.
