In 2007 wind energy capacity reached 1% of global electricity needs. In just 4 years wind energy capacity has grown to reach 2.5% of global electricity demand. And by the end of 2011 it will be close to 3%.
By the end of 2011 globally wind energy capacity will exceed 240,000 MW of capacity. As of June 30, 2011 capacity stood at 215,000. And at the end of 2010 it was 196,000.
As the chart shows Chinese wind energy capacity has been exploding. From the end of 2005 through the end of 2011 they increased capacity by over 3,400%. Global capacity increased by 233% in that period. The 8 countries shown in the chart made up 79% of wind energy capacity in 2005 and 82% at the end of 2010. So obviously many of other countries are managing to add capacity nearly as quickly as the leading countries.
USA capacity grew 339% from 2005 through 2010 (far below China but above the global increase). Germany and Spain were leaders in building capacity early; from 2005 to 2010 Germany only increased 48% and Spain just 106%. Japan is an obvious omission from this list; given the size of their economy. Obviously they have relied heavily on nuclear energy. It will be interesting to see if Japan attempts to add significant wind and solar energy capacity in the near future.
