Is Solar PV even a source of energy when one considers trying to ‘buffer’ it with storage? Does the energy cost of building the solar PV AND the storage render solar PV a net energy SINK rather than energy source? Or, in other words, do you pour more coal and gas and oil into building solar PV + storage than you get back as ‘clean’ energy? Apparently so! Not only this, but we need a minimum of 12 times the energy return on energy invested (ERoEI) to run the modern world. Solar thermal + storage only gives us 9, and that’s the best performing! Sorry folks. The ERoEI of a renewable grid + storage seems to be too low. Nuclear has an ERoEI of about 75. It’s nuclear or it’s climate change. The science says so.
