The United States depends on fossil fuels, like oil and coal, for energy. According to experts these sources will exhaust by the year 2050. Fossil fuels also pollute the environment. So we need to search for alternative energy sources which are reliable and renewable. Wind power is the force of the wind harnessed by windmills and wind turbines that convert it into electricity. Because wind is a clean and renewable source of energy, modern wind turbines …showed first 75 words of 480 total…

A futuristic scheme that has been proposed to produce power on a large scale envisions placing giant solar modules in geosynchronous earth orbit, where energy generated from sunlight would be converted to microwaves and beamed to antennas on earth for re-conversion to electric power. Unless we contrive more efficient ways to develop alternative energy within this century we will face major problems because energy consumption is increasing year by year, so do the pollution.
