A new research report from the Worldwatch Institute states that China leads in the global growth capacity for installed wind power.
The global growth rate for wind power capacity is continuing to grow at a lower rate than before due to various factors.

In 2011, the global installed wind capacity was four times more than that in 2005. In 2011 it grew at 21%, in 2010 at 24% and in 2009 at 31%. The investments for global wind energy installations in 2011 went down by 22% to $75 billion.
