If you want green energy there’s nothing cheaper than hydroelectric. Fortunately my state is relaxing the regulations for retrofits on hundreds of dams in the state.

Its like anything else, cost effectiveness is related to availability.

Colorado? Loveland had a hydro plant that got destroyed by the big Thompson flood. It was quite effective. Longmont had a hydro plant that they planned on closing when the operators retired. It generated more than enough to power the water plant as some other utilities. Some of these do not even require a dam, just a diversion structure. There is a greater energy density with hydro than with wind.

And during a season of low precipitation, with competing interests from agriculture, hydroelectricity can also be scaled back.
