Science Friday recently had an episode about Americans' eating habits. For one, we don't eat enough fruit and vegetables. But also, we waste a lot of food: 27% by the estimate of one of the guests. This is similar to the third of food thrown away by Britons; the difference is probably largely in the methods of estimation and definitions. Since food production take no small amount of fuel, the SciFri guest estimates that 2% of all energy use in the U.S. goes to food that is thrown out. This not may seem like a lot, but there being 50 states, it is equivalent to the entire energy consumption of the "average state." Or as they say on SciFri, more energy than the output of the whole ethanol industry.
