Renewables Race: California's Clean Power QuestThe state of California hopes to have 33 percent of its energy come from renewable sources by 2020. In a partnership with KQED, NPR is exploring the technology, challenges and politics associated with the state's ambitious goal.
Out Of Thin Air: California has set ambitious targets for renewable energy generation for the state. Wind power, including electricity generated by these turbines at the Altamont Pass wind farm east of San Francisco, will play a key role in meeting the state's goals.

This shipping container turned battery holds enough power for 1,500 homes and is made of 83,000 small lithium-ion battery cells. Electric grid operators can use battery technology like this to help smooth out fluctuations in electricity as a result of the irregularities of using renewable sources like wind and solar power.
Renewable energy advocates are looking to geothermal sources like this plant in Calipatria, Calif., to provide electricity to help California meet its goal of generating 33 percent of its power from renewable sources by 2020. But some conventional geothermal sites are, quite literally, running out of steam.
