Electricity is a fundamental part of nature. We can define it as the flow of electric charge that can be positive and negative . Electricity can occur naturally, such as in lightning, or it can be produced via a generator. Now, let’s look at the history of electricity to see how people harnessed it.

History of Electricity

The discovery of electricity played a massive part in pushing human civilization forward. From the following sections, you will learn who discovered electricity and how they did it.

Ancient Times

The earliest records of electricity come from Egypt. Ancient Egyptian texts depict a smooth-skinned fish with a long head, tiny eyes, and a round snout with three pairs of whiskers. Egyptians referred to this fish as “Thunderer of the Nile” or an electric catfish . Several ancient writers attested to the effect of electric shocks delivered by electric catfish. For example, it was used for treating gout and headaches.

The earliest known discovery of electricity dates back to 585 BC. Thales of Miletus recognized the attractive powers of amber rubbed with animal fur. He attributed it to the objects having a soul, but what he really observed was static electricity.

Early Modern Era

In the 16 th century, English scientist William Gilbert discovered that our planet has two magnetic poles and that longitude is correlated with a magnetic variation. He created the world’s first electroscope to detect electric charge. He also coined the New Latin word “electricus,” which soon became the English word “electricity.”

In 1650, Otto von Guericke invented the first air pump that produced static electricity. Later in the 18th century, Benjamin Franklin proved that electricity and lightning are the same phenomena. He did it by attaching a metal key to a kite string and observing it being charged during a thunderstorm.

In 1791, Luigi Galvani saw a spark of electricity make a dead frog’s leg move. It occurred when two different metals came in contact with the frog. Alessandro Volta used Galvani’s discovery to invent the first electric battery, known as the voltaic pile.

Industrial Revolutions

The late 19th century saw the most significant progress in electrical engineering. Some examples include:

• Joseph Henry’s discovery of electromagnetism;
• Alexander Graham Bell’s invention of the telephone;
• Thomas Ahearn’s streetcars;
• Wilhelm Roentgen’s discovery of X-rays ;
• Thomas Edison’s invention the phonograph andthe light bulb;
• Nikola Tesla’s invention of wireless communication;
• Joseph John Thomson’s discovery of electrons, and many more.

These scientists turned electricity into an essential tool for modern life.

In 1905, Albert Einstein demonstrated that the energy of light could be used to produce electricity. This discovery led to the quantum revolution. Einstein was awarded the Nobel Prize for his work on the law of the photoelectric effect. His findings made it possible to produce electricity with solar panels.

Greenleaf Whittier Pickard invented the crystal detector. It was one of the first devices for receiving radio broadcasts in the early 20th century.

Life Without Electricity

Introduction:  Have you ever wondered if it is possible to survive without electricity? Most of us can handle a day or two, but can we survive for several months or even years? Electrical power cuts are becoming more frequent, which affects more and more people. Thesis statement : Despite surviving thousands of years without electricity before, people are wholly reliant on its power and would have trouble surviving without it today. Body paragraphs: The more technologically advanced the world gets, the more dependent on electricity it becomes. Each year, the world experiences a power shortage caused by natural disasters, bad weather, or power line faults. People get disrupted in their daily routines. They cannot get their laptop charged, use their freezer, and turn on the lights. Two critical things that we need in our life the most are heating and water. Without electricity, they both are compromised. It is hard to imagine surviving without these necessities, as we rely on readily available power. Conclusion: A life without electrical power will not be easy for most people. We are so dependent on electricity today that we feel extremely vulnerable when a power outage happens. While taking electricity for granted, we use it without thinking twice.

❓ Essay on Electricity: FAQ

How do we save electricity.

We can practice energy conservation by using less energy. It will help reduce environmental impact and lower the cost of electricity. Saving energy starts with adjusting our day-to-day behavior and using energy-efficient appliances. Even small changes in habits add up over time, reducing our impact on the environment.

What is Electricity?

Electricity is a flow of electric power or charge. It is a phenomenon that occurs naturally in the form of lightning. Electricity is also a secondary source which means that it can be converted from other sources of energy like coal, oil, natural gas, or nuclear power.

Why is Electricity Important?

Electricity is an essential part of our civilization. We use it for lighting, heating, cooling, and charging numerous devices and appliances. Since the Industrial Revolution, most inventions have been designed to be powered by electricity. Electrical power enhances our quality of life and stimulates the world’s economic productivity.

What Would Happen If We Had No Electricity?

If electricity disappears, the immediate problem would be water shortages since the pumps would stop working without electricity. Consequently, there will be no access to basic necessities. We rely on electricity so much that the transition to life without it would be slow and challenging.

History of electricity

by Chris Woodford . Last updated: December 3, 2021.

I f the future's electric, why isn't the past? Think a little bit about that simple-sounding question and you'll understand what science is all about and why it matters so much to humankind. Consider this: the ancient Greeks knew some basic things about electricity over 2500 years ago, yet they didn't have electric cookers or fridges , computers or vacuum cleaners . How come? Electricity is just the same as it was back then: it works in exactly the same way. What's changed is that we understand how it works now and we've figured out effective ways to use it for our own ends. In other words, science (how we understand the world) has gradually helped us to produce effective technology (how we harness scientific ideas for human benefit). The steadily advancing science of electricity has led to all kinds of electrical technologies that we can no longer live without. It's been an incredible achievement, but where and how did it begin? Let's take a closer look!

Ancient sparks

Way back in 600BCE, a Greek mathematician and philosopher named Thales (c.624–546BCE), who lived in the city of Miletus (now in Turkey), kicked off our story when he discovered the basic principle of static electricity (electricity that builds up in one place). As he rubbed a rod made of amber (a fossilized tree resin), he found he could use it to pick up other light objects, such as bits of feathers. (You've probably done a similar experiment rubbing a ruler or a balloon and using it to pick up pieces of paper.)

Before Thales came along, people might well have explained something like this as magic: ancient people didn't reason things out scientifically the way we do today. Their explanations were often a muddled mixture of magic, superstition, folklore (stories), and religion. [3] Thales is often called the world's first scientist, because he was one of the very first people who tried to find sensible, rational explanations for things. His explanations weren't always correct (he thought everything in the Universe was ultimately made of water and believed Earth was a flat disc), but they were the best logical deductions he could make from his observations of the world—and, in that sense, they were scientific. [4]

The logical, scientific ways of doing things we rely on today were developed by later Greeks such as Aristotle (348–322BCE) and Archimedes (287–212BCE), who built on Thales' work, and Islamic scholars such as Alhazen (965–1040CE), who gave us the scientific method : coming up with a tentative explanation for something (a hypothesis), which is then tested through experiments to make a more robust explanation (a theory). Important though these people were, electricity (as we know it today) didn't figure in their thinking. They had little conception of how useful it could be—or what it would eventually lead to. They were more concerned with astronomy, mathematics, matter, and optics (how light works). Science might have been in its advent, but electricity was still just a "magical" curiosity—of very little practical use.

Positive and negative

Incredibly, the scientific study of electricity didn't really advance any further for a full 2000 years after Thales' original discovery. But around 1600CE, Englishman William Gilbert (1544–1603), a physician to the English Queen Elizabeth I, started to probe it further. Gilbert was the person who coined the Latin term "electricus" (a word meaning "like amber," reflecting Thales' original discovery) and he believed electricity was caused by a fluid called "effluvium" that could move from place to place. This was an important insight because it was the first real suggestion that electricity could form what we now call a current, as well as remain static (in one place). Although Gilbert is much better known for his work on magnetism (he made the important deduction that Earth behaves like a giant magnet), and compared it with electricity, he didn't unite the two things in a single theory. If he'd done so, he probably would have gone down in history as one of the greatest physicists of all time. (As we'll see later, the person who finally achieved that, James Clerk Maxwell, is celebrated in exactly that way.)

It was now becoming clear that there was much more to electricity than the ancients had realized. In 1733/4, almost 150 years after Gilbert's death, a French physicist named Charles du Fay (1698–1739) made the next important breakthrough when his experiments revealed that static electricity could come in two different (opposite) flavors, which he named "vitreous" and "resinous." If you rubbed some objects, they gained one kind of electricity; if you rubbed others, they gained the opposite kind. Just as two "like" magnets (two north poles or two south poles) will repel, so two objects with "like charges" of electricity will also repel, while objects with unlike charges (like magnets of opposite poles) will attract. Although we now know this idea is correct, back in the 18th century, such a convoluted explanation sounded wrong to some people. Why should there be two kinds of electricity? Didn't it flout a basic scientific principle called Occam's razor —the idea that explanations should be as simple as possible? Englishman Sir William Watson (1715–1787) thought there was just one kind of electricity, with an ingenious explanation much more like our modern view: if we have too much electric charge, it seems like one kind of electricity; if too little, the other kind. Watson gave us the concept of electric circuits (closed paths around which charge flows) and made an important distinction between conductors and insulators. He was also one of the first to show that electricity could zip down very long wires, and his other experiments included passing electricity through lines of several people to give them surprising electric shocks.

Two decades later, the question of how many kinds of electricity there were was effectively settled by Watson's contemporary, the American polymath Benjamin Franklin (1706–1790). Printer, journalist, inventor, statesman, scientist and more, he made all sorts of contributions to 18th-century American life. One of his most important achievements was confirming that there was a single "electric fluid," giving rise to the two "kinds" of electricity, which he named (as we still do today) "positive" and "negative." Like Watson, Franklin helped to tease out the mystery between static and current electricity. In his most famous (and indeed most dangerous) experiment, he flew a kite in a thunderstorm with a metal key attached to it by a long string. The basic idea was to catch electrical energy in the clouds (static electricity) from a lightning strike (current electricity), which he hoped would travel down the string to the key (more current electricity). Fortunately, lightning didn't strike the kite, which might well have killed Franklin, but he was able to detect charges and sparks, so confirming his ideas. DON'T try anything like this at home! [5]

“ And when the rain has wet the kite and twine, so that it can conduct the electric fire freely, you will find it stream out plentifully from the key on the approach of your knuckle. ” Benjamin Franklin, 1752 [12]

Franklin's electrical research marked a new milestone and hinted of much more to come, because it suggested electricity could be captured and stored as a form of energy. But electricity turned out to be even more useful when people discovered how it could exert a force. That was demonstrated by Frenchman Charles Augustin de Coulomb (1736–1806), who charged up two small spheres with positive electricity and then measured the (repulsive) force as they pushed away from one another (repelling the same way as two magnets with like charges). Coulomb found that the force between charges depended not just on their size but also on the distance between them—something now known as Coulomb's law. (The basic unit of electric charge is also named the Coulomb in his honor.)

Electrical experiments were still hampered by the sheer difficulty of making and storing electricity, which, at this time, essentially relied on rubbing things to build up a good static charge. The study of electricity really advanced when a group of European scientists devised ways of storing electrical charges in glass jars with separate pieces of metal attached to the inside and outside surfaces—devices known as Leyden jars, which were the first effective capacitors (charge-storing devices). Developed independently in the 1740s by German Ewald Georg von Kleist and Pieter van Musschenbroek (of the city of Leyden, hence the name), they offered a much more convenient way of studying electricity.

Animal magic

Ever since Thales' original discovery, scientists knew that static electricity could be made by rubbing things, but no-one knew exactly why this was so or where the electricity ultimately came from. In the late 18th century, Italian biologist Luigi Galvani (1737–1798) found he could make electricity in a completely different—and totally unexpected—way: using the legs of a dead frog. In his most famous experiment of all, when he pushed brass hooks into a frog's legs and hung them from an iron post, he saw the legs twitch from time to time as electricity flowed through them. That led him to think that living things like frogs contained something he called "animal electricity," which the metals were somehow releasing.

Artwork: Luigi Galvani believed he'd discovered "animal electricity" when he hung a frog's legs from a metal hook (left) and watched them twitching. Illustration courtesy of US Library of Congress .

In fact, as another Italian, physicist Alessandro Volta (1745–1827) soon discovered, Galvani had leaped to the wrong conclusion. The twitching frog was merely the current detector, not the source of the current. The important thing, as Volta discovered when he experimented with all sorts of different materials, was "the difference in the metals." What was really happening was that the two different metals, connected through the moist, fleshy, froggy tissue, were producing electricity chemically. Volta managed to recreate this effect with discs of two different metals, silver and zinc, separated by pieces of cardboard soaked in saltwater, and that was how he came to invent the world's first proper battery —an invention that revolutionized the history of electricity. It was a perfect example of how a scientific discovery can be rapidly turned into a practical technology—and one that allowed science to advance even further by making experiments easier. Even in Volta's time, the discovery was considered so impressive that the inventor was asked to demonstrate it before the great French emperor Napoleon I, who set up the Galvanism Prize in his honor. (His nephew, Napoleon III, set up a Volta Prize to reward great scientific discoveries some years later.)

Volta's invention also led to the development of a new branch of science called electrochemistry. One of its founding fathers, Sir Humphry Davy (1778–1829), used a kind of electrochemistry known as electrolysis (effectively, making a battery work in reverse) to discover a number of chemical elements, including sodium and potassium, and later barium, calcium, magnesium, and strontium. Fittingly, he was awarded a Galvanism Prize for his work in 1807.

Magnetic attractions

There's electricity—and there's magnetism. That's how people like William Gilbert saw the world and it's still how we study it in schools to this day. The idea is not wrong, but it's a little bit misleading, because electricity and magnetism are essentially two different ways of looking at the same, bigger phenomenon. They're like two sides of the same coin or the front and back of a house. There had been various clues about the links between electricity and magnetism over the years. (In 1735, for example, the scientific journal Philosophical Transactions of the Royal Society of London had carried "An account of an extraordinary effect of lightning in communicating magnetism" : according to a doctor in Yorkshire, a lightning bolt had struck the corner of a house where a large box of metal knives and forks were stored, scattering them around and, curiously, magnetizing them in the process.) But the definitive connection between electricity and magnetism was really first established by a series of revolutionary experiments that European scientists carried out in the 19th century.

The person who gets the credit for discovering what we now know as electromagnetism was Danishman Hans Christian Oersted (1777–1851), a physics professor in Copenhagen who had been inspired by Volta's invention of the battery. [6] Around 1820, during a student lecture, he just happened to place a compass near an electric wire and switched on the current. Incredibly, he noticed that the sudden current made the compass needle move, while reversing the current made the needle move the opposite way, suggesting the electricity flowing through the wire was making magnetism (because that's what a compass detects). [7] Though this was a major discovery, it wasn't the first proof of electromagnetism. About 20 years earlier, an Italian philosopher named Gian Domenico Romagnosi (1761–1835) had done a similar experiment, but few remember him today. [8]

Animation: Oersted's experiment: When he placed a compass near a wire and switched on the current, the compass needle moved one way; when he reversed the current in the wire, the needle moved the opposite way.

“ ...the magnetical effects are produced by the same powers as the electrical... all phenomena are produced by the same original power ” Hans Christian Oersted [9]

After learning of Oersted's work, Frenchman Andre-Marie Ampère (1775–1836) carried out another groundbreaking experiment with two wires placed side by side. When he switched on the current, he found the wires could push apart or pull together. One of his important conclusions was that a current-carrying wire makes a magnetic field at right angles, in concentric circles around the wire—rather like the ripples on a pond when you drop a stone into it.

This was all very interesting, but what use could it possibly be? Step forward English chemist and physicist Michael Faraday (1791–1867), originally an assistant to Sir Humphry Davy, who took "Ampère's beautiful theory" (as he called it) a stage further. [10] Ingeniously, he found he could make a wire rotate by passing electricity through it, because the flowing current created a magnetic field around it that would push against the field of a nearby magnet—and so invented a very primitive and not very practical electric motor . A few years later, he realized this invention would also work in reverse: if he moved a wire through a magnetic field, he could make electricity surge through it. That marked the invention of the electricity generator —a simple but revolutionary device that now provides virtually all the electricity we use to this day. Faraday, though he stood on the shoulders of Oersted, Ampère, and those who came before, arguably made the greatest contribution to our modern age of electric power.

Faraday wasn't the only pioneer of electromagnetism, however. Elsewhere in the UK, William Sturgeon (1783–1850), a brilliant but undeservedly forgotten inventor, was carrying out very similar experiments. In 1825, between Faraday's inventions of the electric motor and generator, Sturgeon built the first powerful electromagnet by coiling wire around an iron bar and sending a current through it. Over in the United States, in 1831, physicist Joseph Henry (1797–1879) made far bigger and better electromagnets (reputedly boosting the strength of the magnetic field by using wire insulated with cloth torn from his wife's undergarments) until he'd built a huge electromagnet that could lift a ton in weight. [11] Powerful electromagnets like this are still used in junkyards to this day to heave metal car bodies from one place to another. The following year, Sturgeon built the first practical, modern electric motor , using an ingenious device called a commutator that keeps the motor's axle rotating in the same direction.

A powerful force

Motors and generators—two parts of Faraday's very impressive legacy—are the twin bedrocks of our modern electric world. Generators make electric power, motors take that power and do useful things, from pushing electric cars down the road to sucking up dirt in your vacuum. But electrical energy doesn't come from thin air; as Volta showed, it doesn't even come magically from dead animals. If we want a certain amount of electrical energy, we have to produce it from at least as much of another kind of energy. That's a basic law of physics known as the law of conservation of energy , largely figured out by Scottish physicist James Prescott Joule (1818–1889) in the 1830s. Joule showed how different kinds of energy—including ordinary movement (mechanical energy), heat , and electricity—could be converted into one another. [13] What Joule's work means, essentially, is that if you want to run a huge city like New York or Sao Paulo off electricity, you'll need to harness huge amounts of some other kind of energy to do it. So, for example, you'll need a giant power station burning huge amounts of coal, hundreds of wind turbines, or a vast area of solar cells .

Making enough energy to supply towns and cities with electricity became possible when a Belgian engineer named Zénobe Gramme (1826–1901) built the first large-scale, practical direct-current (DC) generators in the 1870s. In 1881, the world's first power plant opened in the small town of Godalming, England. The following year, Thomas Edison (1846–1931) built the first full-scale power plant at 257 Pearl Street in Manhattan, New York City. While Edison opted for plants that produced DC electricity, his former employee turned bitter rival Nikola Tesla (1856–1943) thought alternating current would work much better, since, among other things, it could be used to transmit power efficiently over very long distances. Tesla teamed up with engineer George Westinghouse (1846–1914), and the two launched a bitter battle with Edison—now known as the War of the Currents —until they'd firmly established AC as the victor. Today, though AC remains the heart of the electricity "grid" systems that provide much of the world's power, DC has again grown in importance thanks, in particular, to things like solar cells, which generate direct (rather than alternating) current.

By the end of the 19th century, electricity and magnetism were happily married in motors and generators, but what was the real connection between them? Why did one produce the other? The mystery was largely solved in the second half of the 19th century by a brilliant Scottish physicist named James Clerk Maxwell (1831–1879). In 1873, building on Michael Faraday's work, Maxwell published a complete theory of electromagnetism, neatly summarizing everything that was then known about electricity and magnetism in four apparently simple mathematical equations . Maxwell's theory explained how static or moving electric charges create electric fields around them, while magnetic poles (the ends of magnets) make magnetic fields. It also showed how electric fields can create magnetism and magnetic fields can make electricity, and tied electromagnetism together with light. This was one of the most fundamental and far-reaching theories of physics advanced so far—as radically important as Newton's work on gravity . Of course, electricity and magnetism were just the same as they had always been. What was different, following the work of James Clerk Maxwell, was a bold new understanding of how they worked together: a revolutionary new piece of science. And as the 19th century rolled on, technology advanced too: with the work of Edison, Tesla, and others, there was a growing understanding of how electromagnetism could put to good use as a practical way of storing and transmitting energy. All that was remarkable enough, but thanks to Maxwell's insights, linking electricity and magnetism to light waves, electromagnetism would soon change the world in another very important way: as a form of communication.

The first inkling of an exciting new form of electromagnetism came the decade after Maxwell had died. Maxwell had realized that electromagnetism could travel in waves. In 1888, a German physicist named Heinrich Hertz (1857–1894) found he could make some of these waves, in which electrical and magnetic energy tangoed through the air at the speed of light. [15] Apart from confirming Maxwell's ideas, this scientific advance opened up another new bit of technology: a practical way for sending information wirelessly from one place to another. English physicist Sir Oliver Lodge (1851–1940), who had been carrying out similar research to Hertz, and Italian Guglielmo Marconi (1874–1937), a brilliant showman with a gift for popularizing science, were among those who developed this technology. Originally called "ether waves," and now much better known to us as radio , it evolved into radar , television , satellite communication, remote control , Wi-Fi , and a whole variety of other things.

The source of electricity

Electricity has always been magical. Imagine how enthralled Thales must have been when he first saw static over 2500 years ago. Or what Heinrich Hertz felt like as he made the first radio waves in his laboratory in Karlsruhe in 1888. At the dawn of the 20th century, electricity seemed magical in all sorts of ways. Thomas Edison was building bold power plants and switching the world to the wonders of incandescent electric light . Marconi, meanwhile, was bouncing radio waves around the world. And there was a new kind of electrical magic as well: the dawning realization that electricity and magnetism originated from tiny particles inside atoms.

The idea that there must be a kind of "particle of electricity" had originally been put forward in 1874 by Irishman George Johnstone Stoney (1826–1911), who had previously studied the kinetic theory (how gas particles carried heat ). [16] Similar ideas were advanced in 1881 by German physicist Hermann von Helmholtz (1821–1894) and Dutchman named Hendrik Antoon Lorentz (1853–1928); together, these three developed the modern "particle" theory of electricity, in which static charges are seen as a build up of electric particles, while electric currents involve a flow of these particles from place to place. But what were the particles? The growing understanding of atoms and the world inside them, by Ernest Rutherford (1871–1937) and his colleagues, offered up a possible candidate in the shape of the electron, a particle Stoney named in 1891. Electrons were finally discovered in 1897 by British physicist J.J. Thomson (1856–1940), while he was playing around with a gadget called a cathode-ray tube, rather like an old-fashioned TV set. [17]

Animation: Solid-state physics explains that electric current is carried by electrons (blue) moving through materials.

During the 20th century, scientists came to understand not just how electrons power electricity and magnetism, but how they're involved in all kinds of other physical phenomena, including heat and light . Known as solid-state physics, these scientific ideas have led to some revolutionary electronic technologies, including the transistor , integrated circuits for computers, solar cells , and superconductors (materials with little or no electrical resistance).

Today, as the world grapples with pressing problems like air pollution and climate change , the need to switch from dirty fuels to cleaner forms of power has made electricity more important to us than ever. Back in Thales' time, electricity was just a take-it-or-leave-it, magical curiosity; today, it's central to our world and everything we do. The story of electricity runs, like a current, right through our past. Thanks to the brilliant work of these scientists and inventors, it also points to a bright and hopeful future.

Save Electricity Essay for Students and Children

500+ words essay on save electricity.

Electricity is an essential resource for a thriving life. It runs our daily life. Life without electricity would be impossible to imagine now. We generate electricity using coal or natural gas. However, people do not realize the natural resources to do as are limited and non-renewable. We must conserve electricity so that we can conserve these resources.

In other words, electricity serves mankind greatly. We must stop the wastage of power. The world will lose its light if there is no electricity. Moreover, careless behavior by humans must be checked. We need to realize the importance of electricity to save ourselves from the darkness.

Need for Electricity

Electricity is needed in almost every sphere of life now. We need it to lead a comfortable life full of all amenities and services. The world will become dormant without electricity. For instance, all our health and education facilities are conditioned by electricity. If there is no electricity, the surgeon won’t be able to perform his surgery. Moreover, students won’t be able to gain practical knowledge.

Likewise, motor mechanics in the garages and engineers in the factory depend on electricity. Furthermore, the passengers at the railway station and the airport can travel safely due to electricity only.

In addition, various means of transportation depend on electricity only. Trams and metros carry thousands of people every day. All this is made possible due to electricity only. Electricity boosts our modern life and helps in making it civilized.

How to Save Electricity

Firstly, all of us must understand that even a small step will go a very long way in saving electricity. For instance, if every person at each home switches on the fan when not in use, thousands of watts of electricity can be saved.

Similarly, if we use our air conditioners, heaters, ovens, refrigerators and more properly, we can successfully save large amounts of electricity.

Furthermore, try making use of natural light more. Do not keep the lights unnecessarily in the morning and afternoons. Make do with the natural light as it is enough. We must replace all our old appliances as they consume a lot of electricity. In other words, we must strive to make our homes energy efficient.

Moreover, always remember to unplug your electrical gadgets when not in use. These devices consume at least 10% of electricity even when inactive. Thus, unplug them to save electricity.

In addition, try to cut down your TV watching time. Encourage kids to read and play outside instead. Likewise, try using laptops in place of desktops. Desktops consume more energy than a laptop. You must also switch off the fans if you using your air conditioner, thereby avoiding unnecessary wastage.

Most importantly, installing solar panels can help you excessively. They are very economical and help in saving a lot of energy. The solar panels will help in consuming lesser energy that too economically. Similarly, the industries which use megawatts of electricity must install windmills. This can help in getting cheap electricity through natural means.

The development of electricity as a source of power preceded this conjunction with steam power late in the 19th century. The pioneering work had been done by an international collection of scientists including Benjamin Franklin of Pennsylvania, Alessandro Volta of the University of Pavia, Italy, and Michael Faraday of Britain. It was the latter who had demonstrated the nature of the elusive relationship between electricity and magnetism in 1831, and his experiments provided the point of departure for both the mechanical generation of electric current , previously available only from chemical reactions within voltaic piles or batteries, and the utilization of such current in electric motors. Both the mechanical generator and the motor depend on the rotation of a continuous coil of conducting wire between the poles of a strong magnet: turning the coil produces a current in it, while passing a current through the coil causes it to turn. Both generators and motors underwent substantial development in the middle decades of the 19th century. In particular, French, German, Belgian, and Swiss engineers evolved the most satisfactory forms of armature (the coil of wire) and produced the dynamo, which made the large-scale generation of electricity commercially feasible .

The next problem was that of finding a market. In Britain, with its now well-established tradition of steam power, coal, and coal gas , such a market was not immediately obvious. But in continental Europe and North America there was more scope for experiment. In the United States Thomas Edison applied his inventive genius to finding fresh uses for electricity, and his development of the carbon-filament lamp showed how this form of energy could rival gas as a domestic illuminant. The problem had been that electricity had been used successfully for large installations such as lighthouses in which arc lamps had been powered by generators on the premises , but no way of subdividing the electric light into many small units had been devised. The principle of the filament lamp was that a thin conductor could be made incandescent by an electric current provided that it was sealed in a vacuum to keep it from burning out. Edison and the English chemist Sir Joseph Swan experimented with various materials for the filament and both chose carbon. The result was a highly successful small lamp, which could be varied in size for any sort of requirement. It is relevant that the success of the carbon-filament lamp did not immediately mean the supersession of gas lighting . Coal gas had first been used for lighting by William Murdock at his home in Redruth, Cornwall, where he was the agent for the Boulton and Watt company, in 1792. When he moved to the headquarters of the firm at Soho in Birmingham in 1798, Matthew Boulton authorized him to experiment in lighting the buildings there by gas, and gas lighting was subsequently adopted by firms and towns all over Britain in the first half of the 19th century. Lighting was normally provided by a fishtail jet of burning gas, but under the stimulus of competition from electric lighting the quality of gas lighting was greatly enhanced by the invention of the gas mantle . Thus improved, gas lighting remained popular for some forms of street lighting until the middle of the 20th century.

Lighting alone could not provide an economical market for electricity because its use was confined to the hours of darkness. Successful commercial generation depended upon the development of other uses for electricity, and particularly on electric traction. The popularity of urban electric tramways and the adoption of electric traction on subway systems such as the London Underground thus coincided with the widespread construction of generating equipment in the late 1880s and 1890s. The subsequent spread of this form of energy is one of the most remarkable technological success stories of the 20th century, but most of the basic techniques of generation, distribution, and utilization had been mastered by the end of the 19th century.

Electricity does not constitute a prime mover, for however important it may be as a form of energy it has to be derived from a mechanical generator powered by water, steam, or internal combustion. The internal-combustion engine is a prime mover, and it emerged in the 19th century as a result both of greater scientific understanding of the principles of thermodynamics and of a search by engineers for a substitute for steam power in certain circumstances. In an internal-combustion engine the fuel is burned in the engine: the cannon provided an early model of a single-stroke engine; and several persons had experimented with gunpowder as a means of driving a piston in a cylinder. The major problem was that of finding a suitable fuel, and the secondary problem was that of igniting the fuel in an enclosed space to produce an action that could be easily and quickly repeated. The first problem was solved in the mid-19th century by the introduction of town gas supplies, but the second problem proved more intractable as it was difficult to maintain ignition evenly. The first successful gas engine was made by Étienne Lenoir in Paris in 1859. It was modeled closely on a horizontal steam engine , with an explosive mixture of gas and air ignited by an electric spark on alternate sides of the piston when it was in midstroke position. Although technically satisfactory, the engine was expensive to operate, and it was not until the refinement introduced by the German inventor Nikolaus Otto in 1878 that the gas engine became a commercial success. Otto adopted the four-stroke cycle of induction-compression-firing-exhaust that has been known by his name ever since. Gas engines became extensively used for small industrial establishments, which could thus dispense with the upkeep of a boiler necessary in any steam plant, however small.

The economic potential for the internal-combustion engine lay in the need for a light locomotive engine. This could not be provided by the gas engine, depending on a piped supply of town gas, any more than by the steam engine, with its need for a cumbersome boiler; but, by using alternative fuels derived from oil, the internal-combustion engine took to wheels, with momentous consequences. Bituminous deposits had been known in Southwest Asia from antiquity and had been worked for building material, illuminants, and medicinal products. The westward expansion of settlement in America, with many homesteads beyond the range of city gas supplies, promoted the exploitation of the easily available sources of crude oil for the manufacture of kerosene (paraffin). In 1859 the oil industry took on new significance when Edwin L. Drake bored successfully through 69 feet (21 metres) of rock to strike oil in Pennsylvania, thus inaugurating the search for and exploitation of the deep oil resources of the world. While world supplies of oil expanded dramatically, the main demand was at first for the kerosene , the middle fraction distilled from the raw material, which was used as the fuel in oil lamps. The most volatile fraction of the oil, gasoline, remained an embarrassing waste product until it was discovered that this could be burned in a light internal-combustion engine; the result was an ideal prime mover for vehicles. The way was prepared for this development by the success of oil engines burning cruder fractions of oil. Kerosene-burning oil engines, modeled closely on existing gas engines, had emerged in the 1870s, and by the late 1880s engines using the vapour of heavy oil in a jet of compressed air and working on the Otto cycle had become an attractive proposition for light duties in places too isolated to use town gas.

The greatest refinements in the heavy-oil engine are associated with the work of Rudolf Diesel of Germany, who took out his first patents in 1892. Working from thermodynamic principles of minimizing heat losses, Diesel devised an engine in which the very high compression of the air in the cylinder secured the spontaneous ignition of the oil when it was injected in a carefully determined quantity. This ensured high thermal efficiency , but it also made necessary a heavy structure because of the high compression maintained, and also a rather rough performance at low speeds compared with other oil engines. It was therefore not immediately suitable for locomotive purposes, but Diesel went on improving his engine and in the 20th century it became an important form of vehicular propulsion.

Meantime the light high-speed gasoline (petrol) engine predominated. The first applications of the new engine to locomotion were made in Germany, where Gottlieb Daimler and Carl Benz equipped the first motorcycle and the first motorcar respectively with engines of their own design in 1885. Benz’s “horseless carriage” became the prototype of the modern automobile, the development and consequences of which can be more conveniently considered in relation to the revolution in transport.

By the end of the 19th century, the internal-combustion engine was challenging the steam engine in many industrial and transport applications. It is notable that, whereas the pioneers of the steam engine had been almost all Britons, most of the innovators in internal combustion were continental Europeans and Americans. The transition, indeed, reflects the general change in international leadership in the Industrial Revolution , with Britain being gradually displaced from its position of unchallenged superiority in industrialization and technological innovation . A similar transition occurred in the theoretical understanding of heat engines: it was the work of the Frenchman Sadi Carnot and other scientific investigators that led to the new science of thermodynamics, rather than that of the British engineers who had most practical experience of the engines on which the science was based.

It should not be concluded, however, that British innovation in prime movers was confined to the steam engine, or even that steam and internal combustion represent the only significant developments in this field during the Industrial Revolution. Rather, the success of these machines stimulated speculation about alternative sources of power, and in at least one case achieved a success the full consequences of which were not completely developed. This was the hot-air engine, for which a Scotsman, Robert Stirling , took out a patent in 1816. The hot-air engine depends for its power on the expansion and displacement of air inside a cylinder, heated by the external and continuous combustion of the fuel. Even before the exposition of the laws of thermodynamics , Stirling had devised a cycle of heat transfer that was ingenious and economical. Various constructional problems limited the size of hot-air engines to very small units, so that although they were widely used for driving fans and similar light duties before the availability of the electric motor , they did not assume great technological significance. But the economy and comparative cleanness of the hot-air engine were making it once more the subject of intensive research in the early 1970s.

The transformation of power technology in the Industrial Revolution had repercussions throughout industry and society. In the first place, the demand for fuel stimulated the coal industry, which had already grown rapidly by the beginning of the 18th century, into continuing expansion and innovation. The steam engine, which enormously increased the need for coal, contributed significantly toward obtaining it by providing more efficient mine pumps and, eventually, improved ventilating equipment. Other inventions such as that of the miners’ safety lamp helped to improve working conditions, although the immediate consequence of its introduction in 1816 was to persuade mineowners to work dangerous seams, which had thitherto been regarded as inaccessible. The principle of the lamp was that the flame from the wick of an oil lamp was enclosed within a cylinder of wire gauze, through which insufficient heat passed to ignite the explosive gas (firedamp) outside. It was subsequently improved, but remained a vital source of light in coal mines until the advent of electric battery lamps. With these improvements, together with the simultaneous revolution in the transport system, British coal production increased steadily throughout the 19th century. The other important fuel for the new prime movers was petroleum, and the rapid expansion of its production has already been mentioned. In the hands of John D. Rockefeller and his Standard Oil organization it grew into a vast undertaking in the United States after the end of the Civil War, but the oil-extraction industry was not so well organized elsewhere until the 20th century.

10 Reasons Why Electricity Is Important

Humans have known about electricity since ancient times, but learning how to harness it didn’t come until 1831. Building on experiments by Benjamin Franklin and others, Michael Faraday coaxed an electric current using magnets and copper wire coils. Today, both fossil fuels and renewable resources fuel electricity. Why is it so important? Here are ten reasons:

#1 Electricity keeps people warm during winter

#2 electricity helps people cook and store food.

Electricity fuels a wide range of devices used for food prep and storage. In the past, people would cook over burning wood or coal, which requires a lot of monitoring. Modern electric devices like ovens and microwaves are more convenient and consistent. Harnessing electricity also paved the way for the invention of refrigerators and freezers, which transformed how people store food.

#3 Electricity heats water

Depending on where you live, your water heater is most likely fueled by electricity. Electric water heaters work by bringing cold water in through one tube, heating it with an electric heating element, and then moving the water through your home with another pipe. If you have this type of heater and the power goes out, the water stays warm for a little while because of the insulated tank. However, without a steady supply of electricity, you’ll be taking cold showers until the power comes back on.

#4 Electricity fuels some toilets

Many toilets operate separately from the power grid, so if your power goes out, you can keep flushing the toilet. Some are on the electrical grid, however, so power outages are even more frustrating. There are also innovations when it comes to electricity and toilets. Electric composting toilets don’t use water, which is appealing to people looking to reduce their water usage. These units plug into the wall.

#5 Electricity is essential for medical care

Healthcare facilities like hospitals depend on reliable electricity. Lighting, security systems, air conditioning, electronic health records, and medical equipment all need energy. Power outages are extremely dangerous for healthcare facilities because they can’t suspend their operations; it can lead to the death of patients. When outages occur, hospitals and nursing homes often have to evacuate, which comes with its risks.

#6 Electricity powers the devices we use daily

Most of us use devices like cell phones and laptops every day. They’re needed for staying in touch with people, working, navigation, and entertainment. There’s a safety factor, too. If you don’t have a cell phone, getting help in an emergency is much harder. Without electricity, you wouldn’t be able to charge these devices.

#7 Electricity powers Wi-Fi

A big reason why devices like cell phones and laptops are so essential these days is that they connect to the internet. The internet is necessary for so many tasks that in 2016, the UN General Assembly passed a non-binding Resolution that called internet access a human right. It’s a symbolic statement since the resolution did not force governments to provide internet access, but more and more groups are pushing for universal internet access. While it’s possible to access the internet without electricity, it’s more complicated. For reliable Wi-Fi, reliable electricity is important.

#8 Electricity impacts climate change

The source of electricity is one of the biggest issues of our time. When it comes from fossil fuels like burn or oil, it drives climate change. According to Our World In Data , 80% of the world’s energy in 2019 came from fossil fuels. Finding renewable energy sources is essential to halting global warming. Some countries have been doing very well. Costa Rica produced 95% of its electricity from wind, solar, geothermal, and hydropower over four years. Sweden, which uses hydropower and bioenergy as its top renewable sources, aims to reach 100% renewable electricity by 2040.

#9 Electricity creates jobs

The electric power industry is a big job creator. It takes a lot of skilled workers to maintain and repair the electrical grid. That includes checking and repairing power lines, getting power back after a severe weather event, and wiring homes and businesses. The green energy sector is also creating lots of job opportunities. According to one report, clean energy is America’s biggest job creator in the energy sector. The wages are higher, as well.

#10 Electricity changed the world

Electricity has had a huge cultural impact. Once people figured out how to efficiently harness electricity, it changed everything. No longer bound to daylight hours, industries could move to shift-based work. This had a huge impact on the economy, as did all the electricity-based inventions that hit the market. Electricity also led to the creation of radio and TV, which influenced society so significantly, we couldn’t possibly describe it here. Long story short, electricity played a major role in the world we live in today.
