ALTERNATIVE FUELS POSSIBILITY OR PARADOX

Shortage of oil will be experienced by future decade's .Fossil fuels have been during mankind over the centuries a nd have come to a stage where they have become a resource. Mankind cannot make requirement to search for alternative energy resources to keep mankind moving. Many authors previously have discussed the importance of alternative fuels. This review presents a detailed description of harness technology, cost analysis and advantage of alternative fuels like bio diesels, Hydrogen energy driven vehicle etc. adopting alternative energy sources will be beneficial for mankind and also will protect environment as th ese release less pollutants in comparison to conventional fuels. . Compared with transitional fuel, alternative fuels have superiority in environment impact, sustainability and energy efficiency. Some of them have been used in reality and shown the potenti al for future fuel. Electricity can also become a future fuel in mid - term period since it has excellent emission performance and low running costs. Hydrogen is expected to substitute conversional fuels in the long term due to high investment costs and curr ent unsustainable production pathway of the latter. The compressed air turned out not suitable for substituting conventional fuels because of poor efficiency and running range performance.
