P.P.S. The reason AC is even used, rather than DC, is with AC you can easily make transformers to change the voltage. (A transformer is like gears on your bicycle.) That way you can transmit huge amounts of power long distances on fairly slender wires, and then transform it down again to be relatively safe for consumers to use.

Q: Where does electricity come from? A: Electricity is a secondary energy source which means that we get it from the conversion of other sources of energy, like coal, natural gas, oil, nuclear power and other natural sources, which are called primary sources .
What''s the difference between AC and DC?
Berggren explains that AC became popular in the late 19th century because of its ability to efficiently distribute power at low voltages. Initially, power is conducted at very high voltages. In order to get these high voltages down to the low voltages necessary to power, say, a household light bulb, it''s necessary to transform the current.
