With the growth of the fuel use around the globe, the problems in front of our environment increase since the more petrolbased fuels we use, the more we pollute the ecosystem of the Earth. This is the reason why many car producers now turn to the alternative biofuels which are produced by different kinds of biomass -an ecologically friendly way to use transportation which would cause almost now harm on the atmosphere and the living organisms in the planet.

The first generation of biofules was developed at first by Swiss scientists, later approved and improved by European, American and Asian specialists. It is mainly produced from animal fats, sugar, strach or vegetable oil. Even though they provide an efficient and more protective way to use transportation, they are still not that effective in preserving the eco system since their production is related with a lot of process that additionally pollute the atmosphere.

However, the first generation biofuels let the scientists to believe that not only the sources used can be the resource of environmentally harmless energy -thus the second and third generation of biofuels appeared. Mainly produced from different crops or crop remainings, these biofuels have become a field of expertise for the Swiss alternative fuel deveopers who now produce harmlessly the green diesel fuel using only remainings from wheat and corn stocks, using grass after being cut from the parks or uninhabited areas as well as remainigs from different already death plants. Thus fuels are gradually becoming more and more efficient and their usage is almost harmless to the environment and the atmosphere in particular.

By currently developing the fourth generation of bio fuels, people are aiming to create a harmless and efficient way to use transportation without the need to destroy wildlife and plant life while refining and extracting oil -petrol fuels not only harm the ecosystem while produced, but significantly influence the negative climate changes when used.
