America has become the world leader in wind power
IN ONE policy area, at least, there is good news for President Barack Obama: his pledge to find alternative energy sources to wean America off its dependence on foreign oil is already being put into action. Last year America ramped up wind-power capacity to 25 gigawatts (GW), overtaking the previous leader, Germany, according to new data from the Global Wind Energy Council. America added 8.4GW of installed power in 2008, more than any other country. China is also investing heavily in wind power, nearly doubling its capacity for the fourth year running. Global capacity grew by 29% last year, the highest annual increase for six years.
