And it mitigates the current red herring of the anti-solar groups complaining that solar “generates too much electricity during the day, and not enough at night”.
With an effective and balanced grid storage system across the country, we can recharge the batteries during the day and then use the power at night.
I think it’s the second one, because every time I’ve heard the objection about the Sun not working at night it has always been in the form of a gotcha and not in the form of a question like, how do we deal with this issue?
