Hydro Power Energy
Energy extracted from the water is known as the hydropower energy. Usually electricity is produced from this energy. The 75% of the earth’s surface is covered with. Today most of the countries produce electricity through hydropower energy. Dams and reservoirs are built on lakes and rivers which collect water and the water goes to the turbines which rotate and extract the energy which produces electricity. Water is an extremely reliable source for producing electricity because not only the water from the seas will never run out but also that a small amount of water can produce electricity enough for a small village.
Today more than half of the world uses water energy to produce electricity. Although this electricity is produced using river water, by forming dams, yet there are many new technologies that can utilize energy from sea current to produce electricity.
