American politicians are driving us off a cliff! The insane policy of subsidizing and promoting biofuels to replace gasoline will only help destroy the earth and the human race at a faster pace. Biofuels are bad because they take more energy to produce than they yield as fuel. Using scarce farmland to grow corn or other crops to produce fuel will only increase food prices, and also increase pollution and top soil erosion. The earth cannot feed our expanding population and at the same time use precious farmland to produce fuel. Higher food prices will starve the poor, increase inflation, which will raise the yearly Social Security cost of living index. This price inflation will make Social Security go bankrupt even sooner.
The only solution to our energy problem is to get out of the carbon fuel cycle completely and switch to hydrogen fuel generated by nuclear fission. We have enough nuclear fuel on hand to last for hundreds of years in the form of nuclear warheads. Nuclear fuel can be reprocessed again and again, and we have the fuel now, already mined and paid for.
