In many courtiers, wind energy has become a major part of their plans for sustainable development. The primary goal of this paper is to analysis advantages and disadvantages of wind power in China and the development potential of wind power in China. In this paper the main methodology is using the information about wind power in China, which is including current situation, development stage, industry development stage, and combining the real case to analysis wind power development potential in China. There are six parts of this paper which are the overview of wind power in china; case description, analysis, conclusions, suggestion, development perspectives and imagination In the first part, the overview of wind power in china, the history of wind power in china, wind resource distribution, wind power development stages, the situation of some key regions, wind  power industry develop stage and also some policies about wind power of Chinese government are discussed. The goal of this part is giving some fundamental information about wind power in China. In the second part, a real case has been described, and according to this case, the construction cost of a wind power plant in China has been discussed. The advantages and disadvantages of wind power are also analyzed based on this case study, such as long-team return, environmental impact, and also some other problem analysis.
