re: A green power grid isn't based in reality with our current technology

I've only seen two locations with all green power that worked. Bonneville Power had all of the damns in the Oregon Gorge and both sides of the cliffs were covered with Wind farms. I have hundreds of distribution transformers on those cliffs.

The other was in Ontario where almost all production is hydro and the Wind Farms were providing power as well.

A wind farm is simply nothing more than a CoGen. That's it ...It cannot operate on it's own as a stand alone source. it must have outside generation.
