Quick Answer: Why is coal important to us?

What is the importance of coal?

Coal is primarily used as fuel to generate electric power in the United States. In coal-fired power plants, bituminous coal, subbituminous coal, or lignite is burned. The heat produced by the combustion of the coal is used to convert water into high-pressure steam, which drives a turbine, which produces electricity.

Why is coal important to our economy?

Coal is America’s most abundant energy resource—making up 90 percent of U.S. fossil energy reserves on a Btu basis. … Coal is essential to the U.S. economy, providing affordable electricity to households, businesses, manufacturing facilities, transportation and communications systems, and services throughout our economy.

Why is coal an important resource to humans?

Coal is the largest source of energy for generating electricity in the world, and the most abundant fossil fuel in the United States. Fossil fuels are formed from the remains of ancient organisms. Because coal takes millions of years to develop and there is a limited amount of it, it is a nonrenewable resource.

Is coal important today?

But despite the scientific and technological breakthroughs of more than 200 years, coal continues to be an important fuel in the 21st century. The U.S. produced about 1 billion tons of coal last year, and about half of the nation’s electricity is generated using coal.
