Hydro Power Generation and Geothermal Energy

Hydroelectricity is a form of energy generated by the motion of water (kinetic energy) and is converted into electricity. Hydroelectric energy is made from the constant motion of the water cycle and it is the result of solar heat and the gravitational forces from the earth. The water cycle starts with the evaporation of water and then it falls back down as rain, hail, or snow. This constant fall of water is what produces the hydroelectricity. Hydropower is fueled by water and driven by the sun, therefore; it is a sustainable fuel source. Other benefits formed from hydropower efforts is flood control, irrigation, and water supply.

Geothermal energy is heat stored deep inside the earth or occasionally in hot springs. This heat is continuously produced by the decay of radioactive isotopes such as uranium, thorium, and potassium. Geothermal heat pump systems can heat and cool buildings and can also provide a source of hot water. Other direct-use applications include growing plants in greenhouses, drying crops, heating water at fish farms, and several other industrial processes. Geothermal energy does not require any fuel and as a result, any kind of pollution or greenhouse gases is not produced
