All About Coal Formed deep underground over thousands of years of heat and pressure, coal is a carbon-rich black rock that releases energy when burned. In the United States, roughly 30 percent of all electricity comes from coal: the rest comes from natural gas, nuclear, and renewables like wind and solar. Most US coal comes from either above-ground mines in Wyoming and Montana, or underground mines in Appalachia.

- Primary energy sources take many forms, including nuclear energy, fossil energy-- like oil, coal and natural gas-- and renewable sources like wind, solar, geothermal and hydropower. These primary sources are converted to electricity, a secondary energy source, which flows through power lines and other transmission infrastructure to your home and business. Learn more about America’s energy sources: fossil, nuclear, renewables and electricity.

The Basics of Nuclear Energy â How is Nuclear Power Produced? Currently, approximately 17% of electricity worldwide is produced by nuclear power plants, but in some countries, like France, over 75% of their electricity is produced by nuclear power (How Stuff Works). The United States, on the other hand, only produces about 15% of the electricity from nuclear power.
