Alternative fuels are the best fuel option for a green future as their emissions are 90% cleaner than the normal petroleum oil. Research has shown that only 20% of gasoline is used for energy and the rest is wasted through heat, pollution and vibration within a car’s engine. The alternative fuel options are environment friendly. They produce minimal greenhouse emissions. Conventional fuel options like petroleum and diesel gas will run out someday. To be on the safe side, alternative fuel options should be used. Statistics state that the number of alternative fuel powered vehicles is increasing rapidly.

The most commonly used fuel Biodiesel is in much debate nowadays. It is an eco-friendly fuel generated from animal fats, algae or recycled vegetable oils.

Another alternative fuel option is Ethanol. It is made up of fibrous supplies like wood chips, starch or sugar present in ordinary harvest like corn. Since Ethanol burns cleaner than gasoline, it reduces greenhouse gases.

The commonly used Vegetable Oil can be used as a fuel for diesel engines. However, it requires some minor modifications like converting old cars into low emanation vehicles. This vegetable oil is heated to a specific temperature to make it appropriate for running an engine.

Compressed Natural Gas is colorless, non-caustic and odorless. It is cheap and clear blazing than diesel or petrol. Vehicles using CNG produces 80 percent less ozone-forming discharges.

Research is being carried out to use Water as a fuel source. Using water as a fuel will produce water vapors instead of harmful pollutants, produce less noise, add cooling to engine and provide better acceleration.

Scientists are finding ways to best utilize electricity to run a car engine. The electric cars are eco-friendly as they don’t produce tailpipe. According to certain reports, there were about 55,000 Full-Electric Vehicles in 2004. However, the number has space-rocketed with an approximate growth rate of 39%.

Researchers have been working on other fuel options like fuel derived from fruit, biogas and ethanol produced from rice. It is expected that many other fuel options will also be available in future.
