California's drought could complicate the state's effort to combat global warming.
The San Francisco Chronicle reported Sunday that a drought stretching on for years could slash the amount of clean energy collected from the state's dams and send emissions spewing from other sources.
California is in its third dry year, and officials say many power-generating reservoirs are low. That forces power companies to buy energy from conventional plants that burn natural gas.
The drought causes farmers to pump more groundwater to irrigate their crops, putting higher demands on the power grid or spewing pollution from diesel-powered generators.
