Carbon Basics
This type of biofuel is commonly made by fermenting sugars from plants like sugarcane or corn.
What is ethanol
During fermentation, yeast converts glucose into ethanol and this gas.
What is carbon dioxide
This biofuel is produced from vegetable oils or animal fats and can be used in diesel engines.
What is biodiesel
Fermentation typically occurs in the absence of this gas, making it an anaerobic process.
What is oxygen
Using biofuels instead of fossil fuels can reduce the emission of this greenhouse gas.
