  • I think most of the technologies you mention are currently still too expensive, can’t be used everywhere or don’t make sense to be used at a large scale. E.g. for pumped hydro you need height differences. Concrete blocks on pullies sound like you need a lot of space for only a small amount of energy (I didn’t do the maths, this is just my feeling, so correct me if I’m wrong).

    About nuclear energy: in the article I saw that it accounts for 18% of the US electricity production. That’s half of the 40% emissions-free part. So for sure we cannot reach the targets without nuclear energy. My opinion is that we should keep using it and keep investigating it further, just as we should keep investigating new electricity storage technologies.
