Also, what does "Clean Electricity" mean? I signed up for CleanPowerSF which only cost me 2¢/kWh more, if I remember right: https://en.wikipedia.org/wiki/CleanPowerSF
In this case I believe it means carbon-free, so Nuclear is still technically viable though very unlikely any new Nuclear will be built. Will be mostly existing hydro, nuclear and geothermal with new solar & wind phasing out gas plants.
