In order to better understand development status of wind power generation in various countries in the world and provide a reference for future research, first introduced the current development status of wind power, including the newly added offshore wind power, cumulative installed capacity, and onshore wind power newly added and cumulative Installed capacity; then introduced and analyzed the current difficulties in wind power generation; finally analyzed the development prospects of wind power, focusing on the future development trend of wind power. The research results show that wind power has broad development prospects and will develop in the direction of large-scale in the near future.
