What exactly Biofuels?

Biofuels provide a potential route to avoiding the global political instability and environmental issues that arise from reliance on petroleum. Currently, most biofuel is in the form of ethanol generated from starch or sugar, but this can meet only a limited fraction of global fuel requirements. Biofuels are a dead end that will slow the adoption of the only feasible solution for personal highway travel. Electrical cars powered by batteries or capacitors are the most technically available and environmentally benign solution. Biofuels are considered neutral with respect to the emission of carbon dioxide because the carbon dioxide given off by burning them is balanced by the carbon dioxide absorbed by the plants that are grown to produce them. The use of biofuels as an additive to petroleum-based fuels can also result in cleaner burning with less emission of carbon monoxide and particulates.

Biofuels in the North are generally derived from feedstocks such as corn and rapeseed that have low energy efficiency and require expensive inputs. And since most arable land in the North is already under cultivation, biofuels are likely to compete with food crops if expansion continues. Biofuel will affect the Amazon rain forest in four ways. First, there will be increased biofuel production in some form. Biofuel means using biological material for energy. Like burning wood in a woodstove for heat.
