Yeah, that’s exactly it. Initially I thought it was pretty much impossible to find suitable locations any more, but apparently there are lots of sites left. Highly populated areas are obviously a lot more challenging. The point is that as opposed to having exactly zero locations, it seems that we do have some options here and there.

Update: here’s an interesting map for potential locations. If you’re in Paris, Berlin, Warsaw, Stockholm or other flat regions, you’re not going to see any pumped hydro any time soon. However mountains of Norway, Spain, France, Italy and Germany look a lot better in that regard.

Actually, Poland, Hungary, and England are probably the worst locations, but fortunately there are still many opportunities elsewhere in Europe.
