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.
Ec = energy contained in the coal fed to the power plant. En = energy contained in the natural gas fed to the power plant (LEBS system only) Eff = fossil fuel energy consumed within the system (e) (a) Includes the energy consumed by all of the processes. (b) Excludes the heating value of the coal and natural gas feedstock from the life cycle efficiency formula. (c) Illustrates how much energy is produced for each unit of fossil fuel energy consumed. (d) Excludes the energy of the coal and natural gas to the power plant.
