>Also ironically: there's been opposition to hydro power in New Zealand on environmental grounds since the government built its first hydro dam in 1901. Protestors are more efficient today and the clean proportion of energy has slipped backward because of the extreme challenges of building another dam.

I imagine if a side of a hill fell and created a lake, these guys would put the hill back together.

But I guess wrong. The more probable scenario is they'd fire up another tax to pay for putting the hill back together, and then they'd just forget to revoke it afterwards.
