Power generation according to Gaia:

Windfarms	Solar Steam	Hydroelectric Dams
Covers vast swaths of wilderness Chops up birds unreliable power, needs gas or diesel backup very expensive	Covers vast swaths of wilderness Flash roasts birds No power in the dark, requires backup very expensive	Covers vast swaths of wilderness Kills fish reliable 24 hr/day power pays for itself
Good	Good	Bad, Bad, Bad...very Bad

Sorry, but hydroelectric dams create more, much more living space for fish than it kills them....

Hydro works if it rains and/or snows enough.

Not so much during a mega-drought, as CA may be in the process of finding out.

Hydroelectric dams

Kills Fish

Fish below dam feed on fish killed by dam, increased food supply results in larger fish than would typically be found if no dam.
