The dirty little secret environmentalists do not want you to know.

It is the dirty little secret because hydro-electricity provides about 15-20 % of the US's electricity. It could provide much, MUCH, more except for the environmentalist's claim that there will be negative impacts on various species on a location by location basis. Seems global warming isn't that much of a concern to them after all.

well what good would it do to lessen global warming a small percentage at the expense of many local ecosystems? The salmon in the pacific NW in particular are decreasing very rapidly because of numerous dams. Remember that that isnt just a loss of a species, but affects the whole ecosystem as well as the local economy.

Hydro-electric is the cleanest and easiest power to create. The fact is that you are making my point of the clip. There is no power that radical hate-group environmentalists would approve of. Wind power kills birds ya know. That's coming. The heat sinks created by solar plants will also create localized heat islands affecting local ecosystems. It is endless.
