=Wind Energy: A Great Alternative to Fossil Fuel.= Have you ever been out in the ocean or in an open field? Did you feel an invisable force pulling at your hair? Well that invisable force is called wind and we can use it to make energy. At the moment, the majority of energy is made from burning fossil fuels like coal and gas, but with the help of wind and a wind turbine, we can stop damaging our ozone through fossil fuels. There are many reasons why wind energy is better than using fossil fuels. It is cheap and abundant, can't run out, and is located in all places throughout the world. It's cheap because wind turbines are not that expensive, and there are lots of them so you have many choises to buy your energy from, especialy in California. Another reason wind energy is good is the fact that wind will never run out, wind is the movement air makes when the light from the sun hits the earth's crust and turns to heat. That heat rises, pushing the other air away creating movements in the air. A great thing about wind turbines is you can put them almost anywhere! You can put a windfarm in the middle of the ocean, an open field, or even your backyard, as long as it can't hit a tree. Another positive reason why America should use more wind energy is because a person can sell the electricity they produce to make a second income. So you can make money and help the environment at the same time! As of 2005, 1% of energy throughout the world has been produced by wind energy. Experts say that if the ten windiest states in the US all use wind energy, instead of fossil fuels, that would off set __all__ of the coal based energy produced in the US. So if each state does its part, than all of America can be coal energy free! Wind energy does not produce carbon dioxide, unlike fossl fuels. The wind turbine works by using the wind around it to create energy. When the wind hits the turbine, the blades on it start to rotate in a circular motion. Since the blades are connected to shafts and generators inside the turbine, the rotation of the blades start a domino affect inside the machine. The end result is energy. Thus, wind energy does not produce carbon dioxide and is therefore better for our environment. So buy a wind turbine today and save money, make money, and help the enviorment.
