Conventional and traditional fuel sources are becoming more and more expensive to extract and the price in the market today is increasing. This is where the Alternative fuels comes in. Alternative fuel source are any materials or substances that can be used as a fuel. Some of the popular alternative fuel sources include bio-diesel, bio-alcohol, chemically stored electricity (batteries and fuel cells), hydrogen, non-fossil methane, non-fossil natural gas, vegetable oil and other biomass sources.
Alternate sources of fuel are promising and it is eco-friendly and affordable. Bio-diesel is an alternate fuel source that is extracted from plants that makes it really friendly in the environment. Bio-diesel is partly renewable; it contains 15% gasoline and 85% ethanol mean that it is at least better than using pure gasoline. Studies also show that water can be an alternative to fuel but studies are still on the process and it requires cars to be converted to water fuel that traditional fuel.
Hydroelectricity is a form of hydropower and is the most widely used form of renewable energy. Another alternative of fuel source is ethanol, it is considered renewable because it is result of conversion of the sun's energy into usable energy. Ethanol is developed from a photosynthesis causing the feedstocks such as switch grass, sugar cane, or corn to grow. These feedstocks are processed into ethanol.
Hydrogen is another source of alternative fuel. Hydrogen produces no pollution and vehicles run by hydrogen fuel cells are two to three times more efficient than gasoline powered vehicles. The ultimate alternate fuel source is the human legs on bike pedals. The bike is really a flawless machine for short to medium commutes. The use of pedals will not only make you save from fuel use but this can be good to the body, health and the environment can benefit from it the most.
