Most of those technologies also need uninterrupted power supplies. Something wind, solar and batteries for the next 50 years aren't.

Pumped hydro is one solution. You bank the excess wind/solar using gravitational potential energy and then draw on that whenever you need to.

Yes, we just need to build the mountains first.

> Batteries are now cheap enough to unleash solar’s full potential, getting as close as 97% of the way to delivering constant electricity supply 24 hours across 365 days cost-effectively in the sunniest places.
What does this mean? It means we are most of the way there with solar and batteries alone, even if we need a bit of carbon based generation to bridge the gap while solar and battery deployments scale globally. Solar and batteries will only continue to get less expensive and better.

Solar PV go brrr.
Have you heard of batteries?
