Geothermal energy is one of the main sources of alternative energy. It is the heat of the earth, which is continuously produced in the core of the earth. It is very beneficial to the earth and it atmosphere as it doesn't produce any pollution. In this technology, Wells are drilled to pump heated water and steam. Then, that steam and heated water are purified to drive wind turbines which produce electricity. It works best in sunny climate regions.
Energy is everything. It can be found in many forms. Fossil fuels cause many environmental issues due to the emission of carbon dioxide. However, alternative source of energy can substitute traditional energy sources with almost no negative effects on the environment. One of the alternative energy sources is solar power. In smaller scale, it is used to heat houses, water and in cooking. In larger scale, it is used to generate electricity. Another source is wind power. Older wind turbines used to grind crops, now to run generators and generate electricity. A third source is geothermal energy, in which, heated water and steam are used to run generators.
