That's the idea, but the battery capacity required would be enormous:

Batteries don't seem likely for a cost-effective replacement, but alternatives may develop down the road.
- snowwindwaves 7y agoIt is unfortunate that link didn't pursue non worst case scenarios, like being able to import some power, or have some non renewable generation used just enough that it was economic to exist at normal energy prices, with the biggest payoff being the avoided cost of energy storage for October and November. that link is kind of unrealistically dismissive.
- gridlockd 7y agoThe question is, can you really go fully renewable with battery storage? If power can be sourced elsewhere but it comes from nuclear or fossil fuels (as in the case of Germany and France), it would be a sham. If everyone went renewable, everyone would also have the same problem of seasonal variance. If you want to go "mostly renewable" and do the buffering e.g. with natural gas as it is currently done, that's of course a far more plausible scenario.
