This isn't so simple. Solar and wind are not just intermittent on a day to day basis, they are intermittent on a seasonal one -- as we saw last year the wind can not blow as strong for months at a time. Much of Europe could be blanketed with a large weather system for days cutting the sun and so forth. Even flow batteries simply can't store enough energy, hydro storage is limited by geography and other solutions are currently niche and have yet to prove scale up. Green hydrogen probably has the most promise as a large scale storage technology that's close enough to natural gas to make workable. Energy is so critical to our civilizations that you can't just make assertions that it'll be OK, you need to be certain. Getting it wrong can be terminal.
