The demand gap is filled too often by fossil fuels. These have their own problems, since cooling water is usually hotter druing a drought. The output of thermal power plants is based on the difference between combustion termperature and cooling (water) temperature. Warmer cooling water makes the thermal power plant less efficient at producing electricity.Click for moreSection Map: Renewable Energy
