re: windmills??
dwh says:
"Can you imagine over 250 windmills to recoup this energy, windmills are huge, I couldn't imagine it. "
You apparently don't live in California.
Raptor deaths are a problem, but they're manageable through siting turbines in the right places and building few but larger windmills (which are more efficient anyway).
I haven't heard of bat deaths as a significant issue, or of any bird deaths besides raptors being very important.
