ADH is produced by the hypothalamus in the brain and stored in the posterior pituitary gland at the base of the brain. ADH is normally released by the pituitary in response to sensors that detect an increase in blood osmolality (number of dissolved particles in the blood) or decrease in blood volume.
Chemical energy is stored in coal. This energy is transferred as heat and stored in water as steam. The energy in steam is transferred to movement in a turbine and to electrical energy in the turbine.
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. Power plants try to remove the sulfur by using low-sulfur coal (anthracite) and machines (scrubbers) to remove sulfur from the emissions.
