I'm not totally sure about that. There is a lot of investment in this area (albeit tossed and blown on the winds of political trends). Things like photovoltaics are only a few years off being viable on a large scale (at current levels of investment which turns out to be the biggest problem).

But I agree it's going to be a struggle and one that may go badly wrong for a while.

But the key thing here is that we have to get the knee jerk politics out of it. It doesn't matter if there is global warming or not because if we stay dependant on fossil fuels there are just going to be endless conflicts over the them, if the greens can persuade everyone in the whole world to live a life of abstinence that's cool - but we need to bet that they can't - because their failure mode is that we all die horribly.

>>The time of cheap power is over.

The time of cheap oil seems to be over.

For the rest: You know that you don't know what will happen. So why do you make blanket statements like that?

For example: Some analysts claim that solar energy will solve all energy problems in ten years. Maybe some of the small fusion projects will work? Thorium? And so on.

Edit: Yeah, since Germany has panicked like a herd of cattle, the time limit is so short that there is very little to do. But the way the electricity prices will go, solar will become attractive earlier.
