Interesting article linked below. Right on point IMHO. "We have built a complex civilization that has literally remade the face of the planet. To do so, we have burned the condensed energy of hundreds of millions of years [of fossil fuels]...we will never have such a bonanza again." When should we pursue energy transition? | SmartPlanet
The right time would have been many decades ago. The longer we wait, the more difficult it will be, and the greater the consequences become.
I share the authors concern about depletion of resources, not just for energy, but metals, water, etc. But the author relies on a peak oil argument to "scare" us into immediate action. I am reposting an WSJ article by one of world's experts in oil supply. Believe it would be probably good enough if we had a medium-long term strategy, but of course we do not have one. http://online.wsj.com/article/SB1000...682563228.html Our Man-Made Energy Crisis - WSJ.com
