I will tell you about the three powers of the world Wind Power, Water Power and Solar Power.Wind power:This capacity is exceeded only by China and the European union 11,895 MW of wind power was installed in 2012 alone, representing 26.5% of new power capacity. Fact about wind power: A 2012 report by a clean energy consuiting group concluded that new wind farms can produce electricity in the 5-8cents per kWh range, making wind power cost-competitive with fossil fuels in many areas. Water power: About 7 % of the total electricity used in the U.S.A. is produced by moving water. Worldwide it is about 19%. Facts about water power: As moving water hits the wheel it turns. The turning wheel sends energy to other tools or machines. Long ago, water wheels supplied the power to do work such as grind grain, saw wood, and run factories. Usally its on a small scale. Water wheels don’t harm the envirment. Power plants are built at the bottom of high dams. Solar Power: Solar power in the U.S.A. includes utility-scale solar power plants as well as local distributed generation, mostly from rooftop photovoitacics, in mid 2013 the U.S passed 10 GW of installed photovoitacic capacity with an additional 0.5 GW of concentrated solar power. In the twelve months through Augest 2014, utility scale solar power generated 15.78 million megawatt-hours, 0.38% of total U.S electricity. Facts about solar power: There are plans to build many other large solar plants in the United States. That is all about the three power s in the world! Wind Power, Water Power and Solar Power.
