I agree with Big Gav. One way or another we are going to have to go with CSP, wind, wave, geothermal - anything that isn't nuke or coal. The sooner we start, the better. Also, the big, Soviet style centrally planned power model is defunct. There will be some, but power generation, mainly from CSP, needs to become local and small scale with battery and grid back up. Conservation is also an absolute necessity - we need to learn to get by with much less. The switch will require quite sophisticated software and systems to ensure maximum efficiency. Not a watt can be wasted!

I lived on a boat for two years (it is how I came to Australia). We, a family of 5, used approx 4.8kWh per day, mostly generated by sun and wind. We didn't scimp. I needed a cold beer (or two, maybe three) every day and "she who must be obeyed" needed ice in her G&T. Having ice on boat mid ocean takes some doing! Now we live in the burbs we use 10 times as much power, not counting the car, the office, the street lamps and all the rest.
