The other thing is from an individual point of view you can live off the grid in a tent but it won't make any difference. Even if your whole country starts living in a tent off the grid it won't make a big change. So why live in extreme discomfort when it won't make any difference, anyway? Instead we need to accept that people will not modify their habits and do something like perhaps cut military spending a smidgeon and direct it into a Manhattan-project style push for better technology for generating power and for using it more efficiently.
This is my view. I believe that AGW is real, but I am not taking any extra measure to save energy in light of that understanding. It won't make a difference if I change my lifestyle. Society has to change its lifestyle. I support green energy initiatives and try to vote for people who seem to get it. I'm willing to pay more for energy if need be. But I'm driving my car just as much as I would otherwise. I'd love to drive an electric car, but mostly for the torque not the efficiency. My electric bill is already about $35 a month, so there is probably little to reduce there.
What we really need is for the powers that be to give up their dreams of petroleum riches and start society on the path to clean, sustainable energy. But a new energy economy is uncertain, while the oil, gas and coal in the ground are known quantities. Those reserves represent potential profit to the energy industry, and they want that money. So they baffle people with bullshit to keep the money train running, putting us all at risk. AGW is an issue that can't wait for oil to get expensive enough, or solar to get cheap enough. Therefore it is not a problem capitalism can solve. But capitalism is what runs the world; maybe over a cliff.
