Document Summary
Hydropower is energy derived from the movement of water in rivers and oceans (or other energy differentials), and can likewise be used to generate electricity using turbines, or can be used mechanically to do useful work. It is a very common resource, taking credit of 19% of global electricity production. The whole concept of hydroelectricity takes advantage of the ability to convert energy from one form to another. The potential energy of water is either naturally or artificially converted into kinetic energy via movement of its atoms. These atoms then transfer their kinetic energy onto a turbine that harnesses the energy to move. This harnessed energy is than transmitted to a generator that than converts it into electrical energy. Geothermal power comes from the greek words, "geo" meaning earth and "thermal" meaning heat. Geothermal directly harnesses the natural flow of heat from the ground. Other countries that have geothermal power stations are japan, iceland, the philippines and the united states.
