My grandma lives in the countryside where is located under the mountain, this winter holiday, when I went to the rural to visit her, to my surprise that numbers of new friends came and located at the top of mountain, yes, these are called wind turbines and bring a new type of energy to our city. It not only changes the old method of electric production, but also save the nature energy such as coal and petroleum. Furthermore, these new friends make a great contribution to the environmental protection and advanced the air quality.
Before wind turbines came, the main source of electricity was burning fuel for continuing operation. Numbers of smoke that include carbon dioxide, sulfur dioxide, mercury, and particulates came out of chimney and cause the air pollution. However, after wind power instead of the fuel consuming, it enhance the air quality of our city. This kind of new power solved the issue of air pollution, no more smoke came out of chimney and improve the environment.
Although wind produces only about 1.5% of worldwide electricity use,it is growing rapidly, having doubled in the three years between 2005 and 2008. In China, the use of wind power is developing every year with 0.2% increase. As a country that is just start this energy production, in my point of view, China still have enough potential to develop this new type of method.
