DESCRIPTION
The global economy is massively dependent on fossil fuels and the every growing nation is becoming increasingly dependent upon foreign sources of crude oil.. The rising energy demand in many rapidly developing countries around the world is beginning to create intense competition for the world’s dwindling petroleum reserves. Furthermore, the combustion of petroleum-based fuels has created serious concerns about climate change from the greenhouse gas (GHG) emissions which is responsible for the global warming. In recent times all the growing nation have new standards for vehicle fuel economy, as well as made provisions that promote the use of renewable fuels, energy efficiency, and new energy technology research and development. For these reasons since a couple of years there is a lot of researches in progress for ALTERNATIVE FUEL like BIOFUEL
