Another relatively sobering book on that topic is called the Long Emergency by J.H. Knustler, which details our dependence upon fossil fuels and the state of emergency that will (may?) ensue following the eventual consumption of world oil supplies past the point of peak oil. A couple factoids from that book remain with me, including the high number of fuel calories needed to put a calorie of food (grain, fruit, vegetable, meat) in our bellies. I can only assume that if/when shortages become real, the relative proportion of available oil resources will need to be redirected toward food - and that the efficiency of farming and marketing systems on a per calorie in versus a calorie out will need to be optimized. It occurs to me that this is an area where farmers and industry will likely lead the way as they will be on the front lines of change. The book Sustainable Energy (Without all the Hot Air) by physicist David McKay helps frame the eventual decline in oil availability by explicitly describing what our long term options are for alternative energy (using the UK as a model) based on current science. That's a pretty grim book as well in some regards, but both authors depict a sea change in human activity in the near future.
