With the ever-ongoing ‘progress’ of the proposed UK nuclear power plants, I wonder if this is the best course of action (not just in the UK, but across other nations also)?

That gravity batteries are so simple it's hilarious: pump water up hill into a tank and it generates electricity on its way back down.

Just in case anyone thinks this is hyperadvanced technology...

    sure, it's just that simple. It's not efficient and pumps wear and need maintenance.

    I think wikipedia gave water pump gravity battery a 60-80 percent efficiency rating, and also said that they can even lose energy. But so what, there's always going to be peaks and troughs in renewable energy production, still a good idea to put the excess to use somewhere.
