Chart of installed wind energy capacity by country from 2005 to 2012

Chart of installed wind energy capacity by country from 2005 to 2012 by Curious Cat Science and Engineering Blog using data from the Wind Energy Association. 2012 data is for the capacity on June 30, 2012. Chart may be used with attribution as specified.

Wind power generation capacity continues to grow faster than the increase in electricity use. The rate of growth has slowed a bit overall, though China’s growth continues to be large.

From 2005-2012 globally wind power generation capacity increased 330%; lead by China with an increase of 5,250%. Of the leading countries Germany grew the least – just 63%. The percent of global capacity of the 8 countries listed in the chart (the 8 countries with the highest capacity in 2012) has been amazingly consistent given the huge growth: from a low of 79% in 2006 to a high of 82.4% in 2011 (2012 was 82%).

Global growth in wind energy capacity was 66% in 2008-2010. In 2010 to 2012 the increase was 28%. The second period is just 18 months (since the 2012 data is for the first half of the year). Extending the current (2010-2012) rate to the end of 2012 would yield an increase of 37%, which still shows there has been a slowdown compared to the 66% rate in the previous 2 year period. The decrease in government subsidies and incentives is responsible for the slowing of added capacity, though obviously the growth is still strong.

From 2005 to 2012 China’s share of global wind energy capacity increased from 2% to 27%, the USA 15% to 20%, Germany fell from 31% to 12%, India fell from 7.5% to 6.8% (while growing capacity 292%).

Hydro power is by far the largest source of green electricity generation (approximately 5 times the capacity of wind power – but hydro capacity is growing very slowly). And installed solar electricity generation capacity is about 1/5 of wind power capacity.
