Electricity
Electricity is the flow of electrical power or charge. It is both a basic part of nature and one of our most widely used forms of energy. Before electricity became available over 100 years ago, houses were lit with candles and kerosene lamps, food was cooled in iceboxes, and rooms were warmed by wood-burning or coal-burning stoves. Electricity is what is called a secondary energy source, or an energy carrier. That means that we get electricity from the conversion of other sources of energy, such as coal, nuclear, or solar energy. The energy sources we use to make electricity can be renewable or non-renewable, but electricity itself is neither renewable or nonrenewable.
