The problem with renewables is the fluctuation. So you need something you can quickly spin up or down to compensate. Now you can do that with nuclear reactors to some extent - but they barely break even at current energy prices, and they keep having the same high cost while idle.
So a combination of grid storage and power plants with low cost when idle (like water) is the way to go now.
And as soon as I learned about that I stopped using it. Turns out it was the right choice - since then more then one company had breaches where authenticator seeds extracted from a google account were used to bypass 2fa.
