Abstract
With the fast depleting fossil fuelreserve and increasing environmentalhazards due to their burning, alternativeenergy sources are being highly debatedand researched from last decade. Thebeginning of 21st century has brought high
investment in this area by variousgovernments around the world due to itbeing centre of world’s politics, resultingin lot of alternative are available inresearch division and market. It isnecessary to inspect whether these fuelsare really promising for future or just afalse note in regards to availability,production, safety, cost, emission andsustainability. According to hubbert’s peaktheory petroleum reserves will last till2050, so we need to switch from
petroleum to some renewable now.Unfortunately petroleum reserve isconcentrated in very few region and mostof them are politically unstable. That makemuch more sense for not to be dependenton only fossil fuels.
This paper aim to review and examinevarious fuels in today’s scenario showingpromising sustainable future. Past studyshows that nuclear energy is mostpromising for future but current crisis in
Japan enforce us to rethink on this. Due tohazards created by man over nature, it triesto restore itself by such natural disaster.
On other hand Blend of petroleum orartificial oil with alcohols and vegetableoil performs do best in regards to
combustion and emission characteristics.Against reported by some authors aboutunavailability of land in production of biodiesel, it should be considered thataround 29% of total government land hasno use. Only in India 36 million hectareland of government is not currently in use,out of which 28 million litre of biodiesel
can be obtained on basis of model of Brazil. Secondly Increasing worldpopulation would make reduce of landavailable for these flues. It should also beremembered that these alternatives may beused in current engines without makingany big changes.
Another promising future shown by solarenergy as it is safe, sustainable andcomparable to price of petroleum economybut the problem with this source is that its
availability does not remain same in allpart of world and efficiency vary overwhole year depend on weather. Anotherproblem with this energy system is thatsolar equipments cannot be movable andtoo heavy in regards to transportationvehicle.
A statically study is done evaluating thesefuels in various categories with differentcredit allotted to each category dependedon scenario in future and suggest
government to invest wisely. It is alsonecessary to suggest transportationindustry about their research divisionshould be focussed on reducing fuelconsumption and developing newpropulsion based on unconventional fuelsources.
