Climate Change mitigation will ultimately be about reducing consumption. Not buying questionable carbon credits, not purchasing green power, but reducing consumption across the board.
For the wealthy proponents of climate change action that SHOULD mean taking every action to reduce initial consumption THEN buying carbon credits and green power for that consumption that you cannot avoid using state of the art conservation measures. If Al Gore is using $1200 monthly in electricity for 4 adults then he's simply not trying very hard at home to reduce consumption.
The right wing gets to kick his butt on this and they get to use left wing facts and data to do it. All over the net there are people with zero-net energy use buildings. (

Al Gore is supposed to have a 30 year head start on this. For him to be anywhere but absolutely in front of the pack on energy conservation while flying around preaching global warming is just pure stupidity.
I support Al Gore. I voted for Al Gore and think that what he's done to get the issue of climate change in the public eye is wonderful.
On conserving energy use at home Al blew it.
