The article, by Dana Visalli, puts the world's daily energy use and production into context, and it's a fairly frightening context. For example, each gallon of fossil fuel takes 98 tons of "prehistoric, buried fossilized plant material". Each day, we burn as much hydrocarbon as the amount of carbon plants sequester in a year. Ethanol's energy return is somewhere between 1:1 and 1.3:1 (although some Brazilian sugarcane gets 8:1). Plus, humans already use about 40 percent of the annual photosynthetic productivity and the best cropland is already being used to grow food. Oh, and the population is growing. Visalli recommends consuming and driving less. Obvious solutions to an obvious problem.
