I’m no physics guy, but it seems to me batteries are only one way to store energy and needed mostly for portable electric use as in vehicles. Battery tech keeps improving. Potential energy can also be stored in other ways, as by pumping water up a hill and then releasing it with the help of gravity to turn turbines to remake electricity. Probably a lot of frictional losses here, and requires investments, but just saying …
My general impression is we have only begun to tap into a renewable energy revolution, which our grandchildren and great grandchildren will hopefully fully enjoy.
Indeed, there are many ways to store excess electricity. I was reading somewhere that in some electric cars they are using capacitors to augment the batteries. I bet that if they tried real hard they could create functional electric cars that run entirely off electricity stored in capacitors.
