Intermittent renewable energy and BEVs don't have to strain the grid, they can reduce the requirement. Just add Vehicle to Grid (V2G) or Vehicle to Load (V2L) with Distributed Energy Resources (DER). Instead of centralizing energy production and storage, why not distribute it. If every home had a solar array sized for not only home use but also BEV use then the grid doesn't have to be expanded. On prolonged days of low output, just drive the BEV to a grid tied charging station and then back home. You've now delivered tens of KWHs to the home without using the grid. This is particularly important for CA, since they will be shutting down their grid from time to time, when fire risk is high. The sad thing about centralized power is, consumers power for, but they don't get any of the advantages of owning it.
