Ethanol fuel. The use of ethanol as a fuel for internal combustion engines, either alone or in combination with other fuels, has been given much attention mostly because of its possible environmental and long-term economical advantages over fossil fuel. Ethanol fuel is an alternative to gasoline.
Ethanol is the type of alcohol found in alcoholic drinks such as wine and beer. It is also useful as a fuel. It is usually mixed with petrol for use in cars and other vehicles. Ethanol can be made by a process called fermentation.he demand for biofuel crops means greater demand on rainforest land. Crops grow slowly in parts of the world that have lower light levels and temperatures, so growing biofuel crops in these countries would not satisfy the demand for fuel. For bioethanol to be burnt in a car engine, some engine modification is needed.
