Why China's Wind Energy Underperforms

Why China's Wind Energy Underperforms

China accounted for 36 percent of global investment in renewable energy last year , pouring $102.9 billion into non-hydro renewables such as wind and solar power. The country is a laggard, however, in maximizing return on renewable energy dollars, especially for wind power. China closed out 2015 with nearly twice the installed wind power capacity of the U.S., yet last year it generated less wind energy. Harvard University and Tsinghua University researchers parse the causes of China’s wind energy gap in a report today in the journal Nature Energy . Using data from 2012, they conclude that delays in connecting new wind farms to the grid, low-quality equipment, and deliberate favoring of coal power over wind by grid operators are each about equally at fault. But that conclusion is surprising on two counts. It downplays the role of China's relatively weaker winds—a factor oft...
