Can California Actually Achieve Carbon Neutrality by 2045?

California Governor Jerry Brown talks during a discussion at the America’s Pledge launch event.

California Governor Jerry Brown has signed a new law mandating that the electricity the state consumes not cause carbon emissions by 2045.

He also issued an executive order that goes even further: It commits California to “achieve carbon neutrality” across the board and not just for power generation by 2045. Together, these steps codify California’s ongoing transition away from relying on fossil fuels for energy. This effort has been ramping up since 2011, when Brown signed another law committing the state to deriving a third of its energy from renewable sources like wind and solar power by 2020—not including big hydroelectric dams.

Based on more than 30 years of research related to solar energy, by my assessment, California can meet the law’s ambitious goal as long as it continues to implement programs that encourage the rapid expansion of renewable energy in the state.

A Growth Industry

The new law actually sets multiple targets rather than just one. It commits California to draw half its electricity from renewable sources by 2026, a share that would rise to 60 percent by 2030.

To take the next step, rather than mandating that all power be renewably sourced, state lawmakers established a 100 percent “zero-carbon” goal. They did not define this term, but it is understood as including wind and solar power, big hydropower plants, and other sources of electricity that do not generate carbon dioxide.
