r pollution. The mechanism for turning wind into electricity is very simple. The wind spins rotor blades mounted on a tower. The spinning blades are linked to a shaft of an electric generator. The turning generator then produces electricity that is carried by power lines. Despite the simple operation of the wind mill, wind power hasn’t been used that much. The main reason is the cost. The United States leads the world in the use of wind power. Windmills account for about 2,500 megawatts of generating capacity nationwide. The production is expected to double by the end of this year, to provide enough electricity for 1.3 million households. The most important factor in making wind power more effective is the location of the wind farm. It is clear that wind power has enormous potential.A jump to solar power would solve about a hundred earthly problems. The most useful form of solar energy reaches the earth’s surface in the form of light. There seems to be no end to the potential use of solar energy being used in the United States. One of the greatest obstacles in the United States is the existing electrical structure. Many people in the renewable industries see the deregulation of utilities as very positive for solar energy. More and more Americans are using solar roofs on their homes. The hope is that the million solar roofs will increase momentum in the United States for more widespread use of solar energy. How quickly Americans can move beyond a thousand roofs and make a leap to full use of solar energy’s potential depends on the answer of one question. Can people imagine a world with a non-polluting source of energy?Hydroelectricity is obtained from the energy contained in falling water. It is a renewable, non-polluting energy source. Hydroelectricity was introduced in the 1880s. The development of hydroelectric power and its share of total electric production varies.For the energy resources, in ...
