Coal explained Mining and transportation of coal
Mining coal. Coal miners use large machines to remove coal from the earth. Many U.S. coal deposits, called coal beds or seams, are near the earth's surface, but others are deep underground.Modern mining methods allow U.S. coal miners to easily reach most of the nation's coal reserves and to produce about three times more coal in …

How electricity is generated
An electric generator is a device that converts a form of energy into electricity. There are many different types of electricity generators. Most electricity generation is from generators that are based on scientist Michael Faraday's discovery in 1831. He found that moving a magnet inside a coil of wire makes (induces) an electric …
