What is energy production? Fermilab

Coal goes from mining to a preparation plant for cleaning and then it is usually shipped by train to the power plants. Most coal in the U. S. is burned to heat water into steam. The power plants where the fossil fuel is burned are called thermal because they use heat energy. Coal burning produces emissions of carbon dioxide and sulfur.

What Are Chemical Reactions That Produce Heat?

Chemical reactions that produce heat are called exothermic reactions. Exothermic reactions involve physical or chemical changes that generate heat in various quantities, which is then dispersed into the surrounding environment.
