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.
Coal & electricity. Coal plays a vital role in electricity generation worldwide. Coal-fired power plants currently fuel 41% of global electricity and, in some countries, coal fuels a higher percentage of electricity.
