We need to wean ourselves off food based on corn and soybeans, particularly meat. This frees up to 90% of current U.S. cropland. We're effectively converting oil into meat while destroying ecosystems. The corn/soy/meat production represents a large (but not majority) chunk of total energy consumption. Biofuels add to this unsustainable industrial activity. While calorie-maximizing grain production is destroying human health by depleting our nutrition, it is correct for engine fuel. Some 10 to 25 percent of the biofuels will be consumed in making more biofuels after fossil fuel is depleted. Another issue is whether 70% of biofuel consumption will be wasted in internal combustion engines as with fossil fuel today. The White House is determined to expand production of fuels, machinery, synthetic fertilizer, factory farming, military, transport and everything else that consumes energy, preferable at even lower efficiency than now (75% of energy is wasted in the U.S.). The cronies will promote biofuels in hopes of decreasing energy efficiency while building up laws and legalities enabling them to corner that energy market. The people's energy is solar and wind.
