  • "Benefits of biofuels". Energy Future Coalition. Retrieved 1.28.08 - "Engines running on biofuels emit carbon dioxide (CO2), the primary source of greenhouse gas emissions, just like those running on gasoline. However, because plants and trees are the raw material for biofuels, and, because they need carbon dioxide to grow, the use of biofuels does not add CO2 to the atmosphere, it just recycles what was already there. The use of fossil fuels, on the other hand, releases carbon that has been stored underground for millions of years, and those emissions represent a net addition of CO2 to the atmosphere. Because it takes fossil fuels – such as natural gas and coal – to make biofuels, they are not quite 'Carbon neutral.'"
