I was just pondering this the other day. Until we figure out a good completely green grid with green backup, we need to compromise. So install as much green power generation as possible and augment it with gas turbine or other backup. Charge double when the backup is running . That will incentivize more conscious use of energy and development of cleaner backup energy.
