Global wind capacity passed 100 GW in the first months of 2008, with more than 7 GW coming online. The US, Asia and Europe, in that order, added between 2.3 GW and 3 GW each. Europe topped 60 GW. The global addition is nearly 29% more than in the same period last year, although the entire 2007 increase over 2006 was even bigger, at 32%. If the 2008 growth trend continues -- and there is every indication it will -- the wind industry will maintain its impressive 25% compound annual growth rate. Leading national markets in the past half year were the US, France, Italy and the Netherlands. Market growth is now mainly constrained by bottlenecks in the supply chain. Supply of gearboxes is increasing rapidly, however, with a combined hike in production volume of well over 10,000 MW in 2008 announced so far this year by just three of the industry's main suppliers.
