Why is Coal Important?
Because of its very high energy content, coal has been an important fuel source for humankind. It is used primarily in power generation, the production of iron and steel, the manufacturing of cement, and the production of liquid fuel. The great majority of coal production is consumed in the country where it is mined. Nearly 40 percent of the world’s electricity production is fueled by coal – more than double the next largest source. In the United States, the number rises to approximately 50 percent. Coal’s use in electricity generation has tripled in the U.S. since 1970. During this same period, emissions from coal-based plants were reduced by one-third. Ninety percent of coal production in America is used for generating electricity, and that works out to 3.8 tons of coal for each American every year. The nation’s demand for electricity is expected to grow significantly over the next several decades. Coal will remain the world’s, the nation’s and Ohio’s energy work horse producing bulk
