Well, every time we have a viable alternative, the greens find some argument against those as well.
Witness the (verbal) attacks against nuclear power. There are so many new regulations (during the Clinton years) on hydro power that the hydro plant near my house can no longer be profitable and is scheduled to close. And what about the wind farms? Too dangerous for birds. Solar? All the panels are causing environmental damage to the deserts they place them in.
Any alternative you come up with is soon attacked as being bad... it soon becomes clear that the anti-oil people aren't really concerned with oil at all... they could be better defined as anti-industry. I reckon if they had their way, they'd mandate suicide by the age of 20, so that we humans wouldn't leave such a scar on mother Earth. The theme music to Logan's Run seems to be stuck in my head right now...
Ain't that the truth. The Greens want us all sitting in the dark. They want rolling blackouts to be permanent blackouts!
