U.S. renewable energy consumption surpasses coal for the ...

Although coal was once commonly used in the industrial, transportation, residential, and commercial sectors, today coal is mostly used in the United States to generate electricity. About 90% of U.S. coal consumption is in the electric power sector, and nearly all the rest is in the industrial sector.. Renewable energy is more broadly consumed by every sector in the United States.

What is coal? - Origin Energy

Most people know coal as a fossil fuel which is used to produce around 40 percent of the world's electricity. 1 It's a flammable black or brown sedimentary rock, and is made mostly of organic carbon. However, there are actually two main types of coal: 'thermal' coal, which is mostly used for power generation, and 'metallurgical' coal, which is mostly used for steel production.
