The Future of Biofuels: Meeting the World’s Energy Security

This article discusses the future of biofuels and the impact on the environment. A brief history of biofuels development is also provided. 

Every year the world consumes 35 billion barrels of oil.

This massive global dependence on fossil fuels contributes to increasing resource scarcity. Scientists have estimated that the earth’s fossil fuel reserves will only last for 50 years. These current estimates indicate that we’ve used almost 50% of our fossil fuel supplies.

This extensive scale of fossil fuel consumption is the main cause of greenhouse gas emissions and climate change. When fossil fuels burn, substantial quantities of carbon dioxide (CO2) are produced and directly emitted into the atmosphere.

Biofuel Development

The increasing global pressure towards greenhouse gas emissions reduction led to the development of a variety of biofuels. This includes biodiesel and bioethanol (corn ethanol, cellulosic ethanol).

This green transition presents a significant challenge to world authorities. Governments are having a hard time addressing the increasing transportation fuel demand that also causes climate change.

There are abundant sources of biofuels globally, however, only 13% of the global energy is derived from this renewable source. To increase the world’s usage and demand of non-renewable energy, biofuels should be inexpensive and readily accessible.

So, will biofuels be used in the future? Continue reading to know more about biofuel and its impact on future energy production and consumption.

What are Biofuels?

Biofuels are derived from renewable sources (biomass) such as plant material and animal waste. This type of fuel has the potential to reduce the world’s dependency on limited fossil fuel supply. In addition, biofuels can also reduce the risk of climate change and greenhouse gas emissions. This is due to its natural carbon cycle production process.


Biofuels can be utilized as a source of energy for commercial and industrial consumption. Like fossil fuels, biofuels meet different energy demands. The most commonly extracted and used biofuels are corn ethanol, biodiesel, and algae.

Moreover, biofuels are classified by their biomass sources and are categorized into three generation biofuel:

First-generation Biofuels

Also known as conventional biofuels, first generation biofuels are mostly made from vegetable oils, sugars, and starch. Examples of first-generation biofuels are ethanol and biodiesel.

Second-generation Biofuels

Also known as advanced biofuels, are biofuels synthesized from non-food crops or lignocellulosic plants. Second-generation biofuels are also derived from agricultural and commercial wastes such as wood residues and waste cooking oil. This type of biofuel is produced using “advanced” technology to extract energy from non-food crops, biomass and waste.

Third-generation Biofuels

Algae biofuel is the ideal third-generation biofuel because of its improved energy reserve property. Algae are organisms that thrive in aquatic environments. These organisms utilize light and carbon dioxide (CO2) to develop biomass. The abundance of biomass present in algae is suitable for biodiesel production and electricity.

Third-generation biofuels will play a significant role in meeting the world’s future energy requirement. Algae biofuel is considered the scientific solution for green and sustainable energy due to its ecological and economical features. Furthermore, microalgae are at the forefront of ongoing global energy advancements. This type of biofuel presents a wider application in the field of renewable energy, pharmaceutical, and bioceutical production.

Future of biofuels and its impact on the environment

Recent studies presented biofuels as the solution to attain sustainable development goals and the net-zero emissions economy by 2050.

  • Firstly, Biofuels utilize the planet’s carbon cycle to reduce greenhouse gas emissions from transportation, industrial, and other commercial processes.

  • Second, because biofuels are derived from renewable plant-based sources, they encourage ongoing development programs for forestry and agriculture.

  • Lastly, advanced biofuels, which are derived from non-food energy resources, utilize waste materials from biomass to create a higher energy density biofuel.

However, most of the newer forms of biofuels are not yet developed and viable for market use.

Even with all the benefits relating to biofuels, its production cost is still higher compared to fossil fuel. Therefore, modern-day production of biofuels should address both economic, and environmental aspects for future market consumption.

Biofuels securing the world's future energy needs

Over the past century, global energy demand has primarily depended on fossil fuels. This contributed to the depletion of non-renewable resources.

In addition, degradation of the environment has been correlated to the development and increasing civilization. For example, land pollution is directly related to increasing land commercialization and urbanization.

The advantages presented by biofuels make them a viable alternative to conventional fossil fuels. Biofuels present a substantial role in combating climate change and securing the planet’s future energy needs.

However, the subject of change is often the major obstacle to the fuel industry. Companies that have long been comfortable with readily available fossil fuels are still dissuaded from using non-renewable resources.

There is an urgent need for countries to produce ecological and economic energy sources. This can be achieved through government, social, and business policy-making collaborations.

To sum up, the long-term goal is to develop an alternative and sustainable energy source for future consumption.

To achieve this, everyone must ensure that different stakeholders (social, environmental, business and government ) are advantageous and sustainable to one another. Thus, biofuels are on their way to becoming the future’s answer towards meeting the world’s energy security.
