It's possible in the Catskills in New York State (USA) but a proposed project there was killed by the greens. Who also killed fracking in NYS and a power line from Quebec to Mass and closed a nuclear plant and ....

Local concerns in my area killed a project as well, though I can say I agreed with their concerns. The power company wanted to cut the top off of a mountain to build the reservoir and were likely going to force a small community to relocate entirely. Not the best solution IMO.

Interesting that “the greens” have so much power in a country which is very strongly two-party in its politics. Or did you mean “environmentalists”?

Yeah we don't really have a green party in the US. I've heard that used as a bit of a derogatory way to refer to environmentalists, or maybe one could say environmental activists.
