Earlier, the safety accident of Sinovel had caused people to worry about whether wind power was developing too quickly. On the 19th, at the 2011 Beijing International Wind Energy Conference, Shi Lishan, deputy director of the New Energy and Renewable Energy Division of the National Energy Administration, said that recently...
The characteristics of China's wind field 1) China's wind field is currently dominated by land-based land, mainly in desert and sandstorm-prone areas. It is raging with wind and sand, long sunshine, and with the change of climate, the environment is worsening; 2) In recent years, offshore wind power has gradually...
According to data released by the National Energy Administration, in the first half of this year, China's wind power generation reached 38.6 billion kwh, an increase of 61% year-on-year, ranking the top of all major energy generation. At present, China's wind power industry has entered a stage of rapid development...
