Spain's grid hits 30% renewables... Thanks to a windy and wet winter, Spanish windmills and dams cranked out so much juice that renewables supplied more than 30% of the country’s power in the past year. With GDP of about $1,500 billion and a population of 41 million, Spain is on par with California. But by comparison the Golden State--though one of the greenest in the US--met 23.5% of its electricity demand with renewables in 2007. President Obama has pointed to Spain as a role model for the US to follow. He wants the nation to to hit 10% renewables by 2010 and 25% by 2025, up from about 8% today.
