"Right now, global food supply is largely sustained through oil-powered “green revolution” technology. In the US, we spend 9 calories of petrochemical energy per food calorie which we consume. In Bangladesh, about 1/2 calorie of human and animal energy goes into producing each calorie of food energy consumed. The petro-energy has meant that we get by with very little human and animal energy. In our equation, it is treated as negligible. A lot of the energy devoted to the calories we eat comes from our cars, refrigerators and cooking devices. Also, we are wasteful of this energetically expensive food. If you throw out half of what you cook, after leaving it sitting in the fridge, you doubly worsen your calorific efficiency." - John Day
