Top Renewable Energy Sources
Geothermal energy is produced from the heat emitted from the earth. Main features of it are that it is clean, sustainable and environment friendly. By the slow delay of radioactive particles, high temperatures are produced continuously inside the earth’s crust. Hot rocks present below the earth heats up the water that produces steam. The steam produced by the heating of water from hot rocks below the earth helps to move turbines. The rotating turbines then power the generators, making geothermal energy another excellent form of renewable energy.
