The discovery of oil has marked a major development in human history. Petroleum and petroleum products have made a great contribution in all aspects of life in general and the energy sector in particular. However, in the face of the advantages we can not help but mention the negative side due to the exploitation and use of oil. And the most significant issue affecting people is the environmental pollution caused by the emissions of fuel combustion. Emissions are a direct cause of climate change. In response to this, people are trying to find alternative sources of energy for oil. And one of the new sources of energy that is said to be effective and less polluting is biofuels. In the 2050s human world program today we will explore the role of biofuels and consider this fuel as one of the key contributing factors to change the world.
