The new 5-year Plan in China assumes 1000 GW of wind by 2050. That's gigawatts.  Renewable press version HERE

According to another recently-issued roadmap drawn up for the country's wind power industry, China's wind power capacity will reach 200 GW, 400 GW and 1,000 GW by 2020, 2030 and 2050, respectively, making wind one of the five major sources of electricity across the country.

"By 2050, wind power projects are expected to address 17 percent of the power demand in China," said Wang Zhongying, director, research fellow at the Center for Renewable Energy Development of the Energy Research Institute, a part of the National Development and Reform Commission (NDRC). The roadmap also predicts that around 2020, the costs of onshore wind power will be equal to those of coal power.

In particular, the roadmap suggests the following timeline:

  * Before 2020, give priority to the development of onshore wind power projects, supplemented by near-shore offshore demonstration projects;
  * From 2021 to 2030, lay equal stress on the development of onshore and near-shore wind power projects, supplemented by far-offshore demonstration projects; and
  * From 2031 to 2050, realize synchronous development of all three types of projects.
