The History of Electricity
Electricity – the science dealing with electric charges and currents http://en.wikipedia.org/wiki/Electricity

Before people had any knowledge of what electricity was, they were much more familiar with electrical shocks – from electrical fish that is. Back in 2750 BC, these fish were known as the “Thunderer of the Nile”. When it was acknowledged that there were numbing effects produced by touching these fish, people suffering from ailments were told to touch these fish. The hope was that the jolt for the shock would produce a cure.

Now let’s fast forward to the 19th century. Thomas Edison, Alexander Graham Bell and George Westinghouse are just a few examples of people who transformed electricity into an essential tool for modern life. Today, almost all electricity made is generated by large power plants. In 2000, electricity is classified as a secondary source of energy. Coal, nuclear power, natural gas and hydropower are considered the major sources used to produce electricity. The percent of energy consumed in the United States is 36% and the electricity production is 3,678 billion kWh. The major uses are manufacturing, heating, cooling and lighting.

How do we get electricity to our house from power plants? Electricity is easily moved and can be moved long distances before it is used. It goes by wire to a transformer where the voltage is upped. The purpose for increasing the voltage is because less electricity is lost when the voltage is high. Once transmitted, the voltage is decreased until it is carried to the distribution line to the house. The voltage decreases again before it enters the house. Electricity is important. Without it, we couldn’t use our refrigerator or stove. Our extra entertainment such as stereos or video games couldn’t be used.

When you are watching your favorite movie or soaking in a hot bath, you probably aren’t aware of the process that was used to help you do those things. Reliability, capacity, base-load, power pools and peak demand play huge roles in electricity. A power company has to be reliable and have the < a href= http://dictionary.reference.com/browse/capacity>capacity to provide you with electricity. Without base-load orpower pools we would be in the dark most of the time. While we may think of electricity as being something simple, maybe even something we may not think about, there is a lengthy process in providing you with the necessities in life. Without electricity, there would be no soaking in a hot bath; it would feel like swimming in the Arctic Sea!
