The Summary of the History of Electricity

The Greeks first discovered electricity about 3,000 years ago. Its name comes from the word «elektron», which means amber. Amber is the fossilized yellow rock found in tree sap. The Greeks discovered that, if they rubbed the amber against the wool, light objects (such as straw or feathers) would stick to it. This form of electricity is known as «static» electricity.

Although people have known about electricity since ancient times, they have only used its power for about 250 years. Benjamin Franklin’s experiments with electricity, including his famous comet experiment in 1752 They showed how little we knew about electricity in the era of the American Revolution and the first industrial revolution.

Benjamin Franklin began working with electricity in the 1740s. He conducted many different experiments to try to understand more about it. Mr. Franklin believed that lightning was like water (that is, a fluid). To prove this, he tied a metal key to a kite and flew the kite during a thunderstorm. When the faucet was charged with electricity, he had proof that lightning flowed like water. Mr. Franklin’s experiments led to his invention of the lightning rod.

We still use many of the words he helped develop to describe electricity today: charge, discharge, conductor, electrician, and electric shock. One of the first major advances in electricity occurred in 1831, when British scientist Michael Faraday discovered the basic principles of electricity generation. Based on the experiments of Franklin and others, he observed that he could create or «induce» electrical current by moving magnets inside coils of copper wire.

The discovery of electromagnetic induction revolutionized the way we use energy. In fact, Faraday’s process is used in modern power production, although today’s power plants produce much stronger currents on a much larger scale than Faraday’s handheld device.

The growing applications of electricity explain the increasing use of fuels such as natural gas, oil and coal in power generation instead of direct uses such as heating or transportation. In 1900, for example, less than two percent of natural gas, oil and coal were used to produce electricity. A century later, 30 percent of our use of natural gas, oil and coal was dedicated to electric power.

Increased access to electricity has illuminated once-dark corners of the world. As international development groups and economists point out, access to electricity is a hallmark of advanced societies and a basic requirement for economic progress. Of course, much remains to be done. In 2009, the International Energy Agency estimated that nearly 70 percent of people in sub-Saharan Africa lacked access to electricity. That means that 585.2 million people remain in the dark.
