Yes, they need heating in winter... for a tiny population. And they have very little in the way of data centres.
Again, these are only suitable depending on the environment you're in. E.g. pumped water storage is only effective if you have the terrain to allow for it (a large hill or mountain with space for a large body of water).
I never said lithium was an outright requirement. I said batteries can't currently take the planet off of fossil fuels, then I said that other energy storage systems are very dependent on the location.
E.g. despite there being a lot of rainfall in the UK, there are only 3 places suitable for pumped water energy storage. It can't be relied upon for powering a country unless you're phenomenally fortunate with geography.
Well, I can think of the inverse - separating a piece of coastline and pumping seawater out when you have excess energy, letting it back in via turbines to get energy. In that context UK does have fitting terrain, it's just underwater.
Seawater is very nasty to machinery though.
Tidal power continues to be researched, but it's proving very difficult, currently completely unviable. It certainly cannot replace all non-renewable energy.
