Activated charcoal is a fine, odorless, black powder. It is produced by heating charcoal to an extremely high temperature in an environment without oxygen, such as a tank. Once activated, the powder's pores trap chemicals, making it effective at treating overdoses and chemical poisonings by preventing the body from absorbing the toxic substances.

Coal is primarily used as fuel to generate electric power in the United States. In coalfired 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 highpressure steam, which drives a turbine, which produces electricity. In 2019, about 23 percent of all electricity in the United States was ...
