Alternatives to fossil fuel based transport liquid fuels include:
Biofuels, which is biomass converted into liquid fuels. The two most common types of biofuels in use today are ethanol and biodiesel. Ethanol is a type of alcohol, made by fermenting any biomass high in carbohydrates (e.g. sugars) through a process similar to beer brewing. Biodiesel is produced by combining alcohol (usually methanol) with vegetable oil, animal fat, or recycled cooking grease. It can also be used as an additive (normally 20%) to reduce vehicle emissions[3].
Synthetic fuels, that can be made from different feedstock, converting biomass to liquid, coal to liquid, or gas to liquid[4].
