Wind Power- the Future Energy Source

Abstract:
We are facing an energy crisis on Earth. Burning fossil fuels are harming the atmosphere; this global warming and affects produces chemicals that hurt our body. People are starting to think about using alternative energy. Wind power would be our first choice, because it’s clean, inexhaustible and renewable. Today, wind power is mainly used in Europe. We believed wind power would be the main source of alternative energy for world use.
Introduction:
Since 400-500A.D, people used windmill energy in farms for grain grinding and water pumping. In 1888, the first wind turbine that generated electricity was discovered by Charles F.Brush in Ohio, USA. However, there are limitations on speed.

It drops almost 90 percent. (Brown 2005) (See Figure 2) However, the U.S was still behind Europe, because of some political and financial issues. Many European countries had started on building windmill projects. Europe comprised two-thirds of the global use of wind electricity-generating capacity. (Brown 2005). The leading countries that use wind power are Germany, Spain, USA, India and Demark. In addition, other countries are now started to utilize wind energy. Asia’s growth is up to 7000KW in 2005. (Florence 2006).

Figure above shows the percentage of electric energy in the U.S. Over 50% of the energy is from coal. This year nuclear energy use was increasing; however, it creates radioactive. Natural gas will pollute the air and caused global warming. According to the National Oceanic and Atmospheric Administration, wind is the fastest growing energy resource. It increased by 46.6 percent by 2005.
