During his fourth inaugural address in Sacramento Monday, Gov. Jerry Brown focused heavily on energy efficiency, calling for further cuts in consumption as a way to combat global warming.
"Taking significant amounts of carbon out of our economy without harming its vibrancy," Brown said, "is exactly the sort of challenge at which California excels."
The governor recommended three items including increasing renewable energy production, decreasing petroleum use and making buildings and heating fuels more efficient.
"This is exciting," Brown said, "it is bold and it is absolutely necessary if we are to have any chance of stopping potentially catastrophic changes to our climate system."
California's landmark greenhouse gas emissions bills mandated that 33 percent of the state's energy must come from renewable sources like wind, solar, geothermal and hydropower by 2020. During his speech, Brown upped that goal to 50 percent by 2030.
