-Some of the energy storage technologies being developed by startups funded by ARPA-E include thermal batteries, thermochemical energy storage, and sulfur-based batteries.
What is the significance of the Diablo Canyon power plant in the context of California's energy policy?
-The Diablo Canyon power plant is significant because it is California's last nuclear power plant, which regulators voted to close. Its closure adds to the grid's costs and inefficiencies and highlights the challenges in transitioning to a fully renewable energy system.
How does the script suggest addressing the variability of renewable energy sources?
-The script suggests that careful analysis of historical data, diversification of renewable energy sources, and investment in cheap, long-term energy storage solutions are key to addressing the variability of renewable energy sources.
What role does research and development play in California's renewable energy future?
-Research and development play a crucial role in California's renewable energy future by facilitating the creation of cheaper and more efficient energy storage solutions, which are vital for a reliable and cost-effective renewable energy system.
