Bio fuels are when you make the best of our land use. Landfills generate and capture methane bio fuels which are then used to heat buildings and power electrical things. Sometimes when farmers want to break down plants, they use bio fuels as their fuel. The way they make bio fuels is by using sugar cane or corn. By doing this 2010 study shows that large scale production in ethanol gas is producing less greenhouse grass income in materials that humans don't eat. These are bio fuels.
