Energy Kids - Electricity in the U.S. File Scrub 1 ::::: EE ... electricity_in_the_united_states-basics Electricity in the U.S. Basics Most of the electricity in the United States is produced using steam turbines. A turbine converts the kinetic energy of a moving fluid (liquid or gas) to mechanical energy. In steam turbines powered by fossil fuels, such as coal, petroleum (oil), and natural gas, the fuel is burned in a furnace to heat water in a boiler to produce steam.
Fossil fuels generate most U.S. electricity In 2012, coal was used for about 37% of the 4 trillion killowatthours of electricity generated in the United States. Natural gas, in addition to being burned to heat water for steam, can also be burned to produce hot combustion gases that pass directly through a turbine, spinning the turbine's blades to generate electricity. Petroleum can be burned to produce hot combustion gases to turn a turbine or to make steam to turn a turbine. Nuclear power provides about one-fifth of U.S. electricity How the Grid Is Organized. How does it work: The coal. Energy Kids - Renewable.
