What are alternative fuels?
Alternative fuels are non-conventional fuels used as an alternative to the 
conventional fuels. Conventional fuels include fossil fuels, coal, natural gas, 
etc., and elements like uranium and thorium which are used in nuclear power 
generation. On the other hand alternative fuels include, Bio-diesel, bio-alcohol, 
natural gas, vegetable oils, stored electricity etc. Alternative fuels are also 
referred to as bio fuels.
Bio fuel is a kind of fuel that contains usable energy in them due to the process 
of carbon fixation that happened recently (Fuel like petrol and diesel are got 
from a source that is formed over a lot of years). These fuels are produced by 
living organisms as opposed to formation solely due to inorganic chemical 
reactions. Bio-fuel can be produced by converting the existing bio-mass to 
energy-containing substances. This is done in three ways: thermal conversion, 
chemical conversion and bio-chemical conversion.
Ethanol
Ethanol is a bio alternative to gasoline. It is produced from the conversion of 
corn, barley and other natural products. The special feature of ethanol is that it 
is the only alternative fuel to gasoline that can run on a gasoline engine without 
any modifications. However, it is only used as an additive today. It is mixed with 
gasoline at different concentrations to cut down the emission dangers caused 
by pure gasoline. A 10% ethanol fuel means a 10% concentration of ethanol in 
gasoline. Most fuel stations in the US have the facility and in some places the 
concentration may even be higher.
Bio-diesel
Bio-diesel is a bio substitute for diesel and it is produced from sugar beet, 
rapeseed or palm oil. It is also sometimes individually prepared from the used 
oil from fryers. It pollutes the environment much less than diesel in that it does 
not produce much carbon-di-oxide. But mass production and continued usage 
of this is undesirable because it leads to afforestation
Vegetable oil
Edible vegetable oil as such isn’t used as fuel; rather, low quality oils can be 
used for this purpose. Over time, vegetable oils are increasingly being 
processed into bio-fuel. Otherwise it is simply removed of its water content and 
other particles before usage. To ensure that the fuel injectors use vegetable oil 
efficiently and atomize it, the viscosity of the oil should be decreased to the 
level of diesel by heating with the use of electric coils or heat exchangers. This 
is easier in warm climates. Some companies even produce that can be run on 
straight vegetable oils without any aftermarket modifications.
Algal bio-fuels
Algal fuel is an alternative to other fossil fuel which is produced from algae. The 
implementation of this fuel in vehicles is not successfully done as yet but 
several companies and the government is pushing forward to the 
standardization of algal fuel as an alternative to main fuels. Algae can be 
converted into fuel using various methods. The lipid, which is the oily part of the 
algae, can be extracted in the same way as fuel is extracted from vegetable oil.
