California’s new energy law (SB 100) is a piece in a larger puzzle

Rooftop solar,storage and energy efficiency still play critical roles

California’s new landmark energy law should be a matter of pride for the whole state. It calls for electricity providers to rely on renewable sources for at least 60% of their delivered power by 2030 and on zero greenhouse gas-emitted sources for the remaining 40% by 2045. People refer to this as the 100% clean energy bill, and it represents a bold new approach for reducing California’s carbon footprint. The California Legislature deserves praise for its dedication to these important issues and for its leadership.

Let’s be clear, however, about what this change is and what it isn’t. The new law is not a 100% renewable energy mandate. The zero-emitting 40% could include large-scale hydroelectric, which is not called “renewable” for the purposes of California’s mandate, and nuclear power. It could even include natural gas or coal-fired power if people can figure out an economical way to capture and sequester all of the related greenhouse gas emissions. Although the new law leaves it to regulators to define what “clean” means, arguably some of the eligible power sources are not particularly clean, as I will explain below. Nonetheless, at this point only Hawaii can boast of a similar broad effort to eliminate carbon-based powerplant fuels.

So, we’re done! Since all power is going to be clean, we are all off the hook. It doesn’t matter how much we use. It doesn’t matter if we generate power on our rooftops, or if we provide community solar parks. We can plug in our cars, set up new districts with neon lights that rival Las Vegas, and get a second or third refrigerator to store beer in the garage — our friendly retail electricity provider will take care of everything.

Well, not so fast. It is still important for us all to do what we can to reduce demand for energy, across-the-board, and shift our usage to periods of lower demand. It is still valuable to distribute power generation throughout a utility service area (closer to customers), add solar photovoltaics to suitable rooftops, and rely on storage in batteries and other devices to make renewable energy available at night and when the wind doesn’t blow.
