Solar energy is produced from solar radiation. Sunlight travels through the upper parts of the earth's atmosphere. Once this sunlight reaches the surface of the earth, it must be captured so it can be turned into an usable energy source.
Electricity production is the primary use of coal in the United States. Most of the coal mined in the United States is transported to a power plant, crushed to a very small particle size, and burned. Heat from the burning coal is used to produce steam, which turns a generator to produce electricity. Most of the electricity consumed in the United States is made by burning coal.
