Wind power is a great type of alternative energy! Denmark gets one fifth of its energy from wind power, the highest percentage of any country in the world. The United States and China are the largest producers of wind power in the world. The largest wind turbine in the world, is located in Hawaii, wich stands 20 stories tall and has blades the length of a football field. An average wind speed of 14 miles is needed to convert wind energy into electricity. In the United States, wind energy now produces enough electricity to power more than 9 million homes. One wind turbine can produce enough electricity to power up to 300 homes. In 200 B.C.,people in China and the Middle East used windmills to pump water and grind grain. Wow even the ancient people knew that alternative energy was a better solution than fossil fuels! Disadvantages: As with any energy source, there are some concerns as well. Once concern is that wind power is not constant. Some days are windier than others. On some days, there is little to no wind. In order for this energy source to be more reliable, it needs to be more consistent so that electricity is being produced all the time. Another concern is that some people believe that the wind turbines are ugly and they do not want them around. Those are just a few concerns about wind power.
