Joe Biden wants 100% clean energy. Will California show that it’s possible?

At-a-Glance:

There are several economic and environmental arguments for the $1.9 billion Pacific Transmission Expansion. The undersea power line would run south from San Luis Obispo County, hugging the California coast for 200 miles before making landfall in or near Los Angeles. It would be able to carry electricity from a fleet of offshore wind turbines, providing Southern California with clean power after sundown and helping to replace fossil-fueled generators. Fewer planet-warming emissions, less risk of blackouts, and no chance of igniting the wildfires sometimes sparked by traditional power lines are among the cases being made for this project.

Key Takeaways:

  • Policymakers across the country are looking to California to show that it’s possible to phase out fossil fuels. State law mandates 100% clean energy by 2045 and, in 2019, nearly two-thirds of California’s electricity came from climate-friendly sources.
  • As demonstrated by summer 2020’s rolling blackouts, there’s a clear longer-term need for clean energy sources that can be relied on when electricity demand is high and there’s not enough sunlight to go around.
  • The Public Utilities Commission unanimously approved a proposal that made its 2030 target to reduce emissions from power plants by 25% the basis for approving or rejecting new transmission lines, which is crucial for connecting renewable-energy facilities with cities that consume large amounts of electricity.
  • Climate advocates are urging Governor Newsom to play a more active role in utility infrastructure decisions to ensure the state is prepared to meet its clean energy targets.

Path to 100% Perspective:

California is a clean energy leader and state-level renewable energy infrastructure decisions made now will likely influence similar decisions across the country. State-of-the-art power-system modeling reveals that California can reach its renewable energy and emissions targets faster by utilizing flexible thermal generation. Flexible thermal generation assets can be converted as needed to use carbon-neutral fuels produced with excess wind and solar energy through power-to-gas technology, forming a large, distributed, long-term energy storage system. Such a system can provide a reliable source of electricity in cases of extreme or variable weather.

Can Biden Get a 100% Clean Energy Bill Through Congress?

Now that President Joe Biden has assumed office, he can get to work on his pledge to move the nation to 100 percent clean energy. During the campaign, Biden advocated a 100 percent clean energy standard pegged to 2035. This builds on state-level renewable portfolio standards, which spurred tremendous growth in renewables by mandating that utilities buy or purchase a certain amount of clean power by certain deadlines.
