Over the 4 year period the capacity in the USA increased 284% and in China increased 1,954%. China grew 113% in 2009, the 4th year in a row it more than doubled capacity. In 2007, Europe had for 61% of installed capacity and the USA 18%. At the end of 2009 Europe had 48% of installed capacity, Asia 25% and North America 24%.
