What are the world’s biggest sources of renewable energy and where are they located?

EFFORTS to tackle climate change include heavy investment in renewable sources of electricity around the world. Solar power saw the biggest leap in 2010, with the installed base jumping 70% compared with 2009 to 40 gigawatts. Wind power also grew strongly, adding 24% of generating capacity. Yet the biggest source of renewable electricity, hydropower, and the smallest, geothermal, both only added 3% to capacity. Finding usable sources of either is becoming increasingly hard or costly. The region that saw the biggest growth in renewable energy projects was power-hungry Asia. Investment in renewables also saw the biggest leap since 2007, with $243 billion spent, a 30% increase over 2009.
