Alternative fuels are also known as non-conventional fuels. They are materials or substances that can be used as fuels that are not the conventional fuels. Conventional fuels can be produced from fuel sources like bio diesel, bio alcohol hydrogen, vegetable oil and biomass sources.

Hydrogen technology is considered as the greatest bridge for the automotive industry in the present scenario. Undoubtedly, hydrogen is a realistic alternative to the world’s present wide-scale use of hydrocarbon fuels. Future would really visualize a green hydrogen car. This might achieve 99 miles per gallon emission-free.

Bio diesel is an alternative fuel for the normal diesel engine since it is more environmentally friendly. Bio diesel fuel is otherwise called a drop-in replacement. Bio diesel can be used in any diesel engine without any modification.

Bio diesel helps to reduce pollutants and engine wear, according to proponents. It can be used either as a pure fuel or mixed with petroleum diesel.

E85 is also an alternative fuel source. It is a composition of 85 percent ethanol and 15 percent gasoline. These fuel sources can achieve high fuel mileage standards. But, E85 is rare to be found or extracted.

You can also use the remnant grounds of caffeine as an alternative fuel. Gasifying the reused grounds can convert them into a burnable fuel. Powering a car with wood is something like running your vehicles on fossil fuels.
