What Are the Advantages of Biofuels?

Mar 23 2021

Fuels that have been extracted from organic matter – normally plants or animal waste – are known as biofuels and represent a potentially eco-friendly alternative to fossil fuels like oil and gas. Whether being used to generate energy in a biofuel plant, power passenger vehicles or as a lubricant in machinery, biofuels carry a number of advantages over traditional fuel sources. Here are a handful of their more important benefits:

Fuel efficiency

When used as a substitute or additive for traditional fuel sources in cars, buses and other forms of road transport, biofuels (like bioethanol and biodiesel) can contribute to increased fuel efficiency. However, it’s always important to ensure that these fuels do not contain contaminants that could erode or otherwise damage the engine. The article Ensure Accurate Results for Sulfur and Chlorine Analysis in Biodiesels has more information on this particular topic.


At the present time, alternative fuels like bioethanol are marginally less expensive to manufacture than petrol. As technology advances and demand increases, the price of producing biofuels is only expected to drop, meaning that their cost-effective in comparison to traditional fuel sources will increase in future. Meanwhile, the environmental costs associated with fossil fuels are also eliminated when they are substituted for biofuels.


Whether biofuels are processed in a power plant or burned in the engine of a vehicle, they produce far fewer harmful emissions at the point of combustion. That’s because they’re made from organic matter like plants and animals, the former of which releases carbon dioxide during the course of its life cycle anyway. Therefore, any emissions associated with the combustion of biofuels are no worse than what occurs in the natural world.


One of fossil fuels’ biggest drawbacks is the fact that it takes millennia for atmospheric pressures to convert organic matter into oil, coal and gas. Since we are using these resources at a far faster rate than they are being replenished, they are a finite source of energy. Biofuels, on the other hand, can be cultivated and harvested with relative speed, making them a renewable and more widely accessible source of fuel.

Durability of engines

Biofuels contain higher concentrations of cetane than fossil fuels, which makes them act more effectively as a lubricant in car engines. This means that the engine requires less maintenance over a longer period of time, increasing its durability and that of the vehicle as a whole. That’s attractive both in economic and environmental terms for the car owner and for the wider community.
