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 is a fossil fuel created from the remains of plants that lived and died about 100 to 400 million years ago when parts of the earth were covered with huge swampy forests. Coal is classified as a nonrenewable energy source because it takes millions of years to form. The energy we get from coal today comes from the energy that plants absorbed from the sun millions of years ago. All living plants store energy from the sun through a process known as photosynthesis. After the plants die, this energy is released as the plants decay.
