Engines running on agrifuels emit fewer greenhouse gases during their entire lifecycle. Produced from raw plant material, these fuels can reduce CO2 emissions by up to 70% compared with 100% petrol use.
Derived from plants – and therefore renewable – agrifuels are ailed at reducing oil dependency. Ethanol is produced from sugar beet, sugarcane, wheat and corn and biodiesel from vegetable oil such as colza.
These highly economical vehicles are particularly widespread in regions where agrifuels are easy to produce, such as Brazil and Argentina. In Brazil, the land of sugarcane, cars run on pure ethanol or ethanol/petrol blends – a solution for reducing the country’s energy dependence and stabilizing the price of sugar, while minimizing the environmental impact of automobiles.
Agrifuels today account for 1.8% of all automotive fuels worldwide (source: Wikipedia).
New, flex-fuel have also made their appearance. These flexible units run equally well on bioethanol or petrol.
