A glimpse of possible futures

One of permaculture’s founder envisions possible futures

An important new site from David Holmgren, one of the fathers of permaculture: Future Scenarios. He writes, "The simultaneous onset of climate change and the peaking of global oil supply represent unprecedented challenges for human civilisation. Each limits the effective options for responses to the other." Holmgren uses a scenario planning framework to bring to life the likely cultural, political, agricultural and economic implications of peak oil and climate change. "Scenario planning allows us to use stories about the future as a reference point for imagining how particular strategies and structures might thrive, fail or be transformed," says Holmgren. Future Scenarios depicts four very different futures. Each is a permutation of mild or destructive climate change, combined with either slow or severe energy declines. Scenarios range from the relatively benign Green Tech to the near catastrophic Lifeboats scenario. (h/t to Adam at Energy Bulletin)

Solar land use: less than coal

Nevada Solar One takes up about 400 acres, mostly for mirrors and heat engines. You would have to mine about 5,300 acres to feed a coal-fired powered plant producing the same amount of electricity. Even acre for acre, I'll take Solar One's pleasant campus over a coal mine. Math below the fold.
