This is all well and good (really), but I'm a bit disappointed that the entire post omits the word "efficiency." Yes, we must do everything he mentions – but we waste a TON of energy. Reducing our demand will only make any other solution(s) easier to achieve. One salient stat: it's estimated that commercial office buildings in the U.S. waste about 30% (!) of the energy they consume. Shameless plug: my startup (bractlet.com) uses physics-based simulation models to try and claw back most of that 30%. If you're interested in that sort of thing, I'd love your feedback on our website/offering. Feel free to email me: brian@bractlet.com
