Sustainable fuel, similar to stem cells, seems like the miracle solution for everyone’s transportation problems. Its use and production are growing all over the world. The entire world can run on the use of biofuels.


Types of Biofuels


The two main types of biofuels are bioethanol and biodiesel. These fuels are categorized into first, second, third, and fourth generations. The first generation fuels are derived from crops, and the second generation consists of biomass, such as plant or animal materials. The third-generation includes algae fuels, and the fourth generation includes electrofuels and solar fuels.


Ethanol fuel is the most widely used biofuel in the world, especially in Brazil and the U.S. It’s derived from the fermentation of wheat, sugar, corn, and other crops, and can be mixed in with gasoline or used as a replacement.


Biodiesel is the most widely used sustainable fuel in Europe. It’s derived from oil or fat and can be mixed with diesel fuel or used in its pure form. It is an environmentally friendly product that does not pollute the soil or water. More than one billion gallons are consumed in the U.S. annually, and over 10 million tons are consumed in Europe.


Current Levels of Production


There are various issues related to biofuel production, such as energy usage, carbon emissions, environmental damage, and the food vs. fuel debate. Researchers are continuing to evaluate the negative impacts of production on society and the environment. Additionally, the government must approve mandates to produce millions of gallons of biofuels.


Despite the criticism, the global production of biofuels exceeded 150 billion liters in 2018. Sustainable fuels helped to run 3% of the vehicles on the road. There continues to be significant plans for the future use of sustainable energy. The International Energy Agency has set plans to reduce a quarter of the world’s dependency on oil and meet biofuel demand by 2050. Currently, the growth of sustainable fuels is estimated to be 3% every year.


It seems that the world will never run out of sustainable fuel. It is also non-toxic to the environment and works as efficiently as nonrenewable energy does. Although there are drawbacks, there are far more advantages that make it a viable energy source in the future.
