The level of investment required to make renewable energy viable for 100% of our energy needs is simply unaffordable. When non-renewable resources stop being a viable source of our energy needs, the entire global human system is going to collapse spectacularly on its arse, and frankly, most people are simply going to slowly die off.

I'm in two minds about this. On the one hand, I'll be teaching my children (to then pass on to their children) ways to survive (and not just survive, but live well, and happily) without relying entirely on modern human convenience. I don't think it's going to be "all over" in my lifetime, or even my children's lifetimes, but my grandchildren and great-grandchildren? I just don't know.

On the other hand - I would rather have them scrape the barrel for as long as they can so that myself and my direct descendants won't have to experience the brunt of that social collapse. Maybe even buy enough time to develop economically viable alternative energy sources, who knows? I tend to doubt it, but then, I'm a pessimist.
