Are you tired of polluting the air with fossil fuels?
Biofuels are living materials, like crops, trees, manure. Garbage can also be used as a biofuel. Biofuels cause less pollution. Crops, trees, manure are burned. This creates steam which can be used to create electricity. It can create pollution, but not as much as fossil fuels. Biofuels are a renewable resource. One disadvantage of biofuels is they cost a lot of money, but it's better than fossil fuels because fossil fuels take millions of years to form. Biofuels will never be gone, and fossil fuels will disappear soon.
