Is biomass a sustainable source of energy?


Biomass is a relatively sustainable energy source that can help reduce our dependence on fossil fuels. It is renewable, meaning it can be replenished over time. It is also reasonably carbon neutral, meaning it does not release harmful emissions into the atmosphere.

Why “a little”? Well, this energy source is not without flaws.

Some environmentalists have argued that this leads to the destruction of forests, a critical habitat for endangered animals. They also say that growing trees, the most common fuel in biomass power plants, takes a while. Additionally, the carbon released when plant matter is burned for energy may not be reabsorbed.

We will address all of these arguments below.

Currently, biomass is used to generate electricity, heat homes and businesses, and power transportation. In the United States, this energy source accounted for about 5% of total renewable energy production in 2017.

There is excellent potential for the further development of biomass as a sustainable energy source. With proper management, it can provide a reliable, clean source of energy with minimal environmental impact. So let’s try to understand this potential alternative to fossil fuels.

What is biomass ?

Biomass is organic matter that can be used as an energy source. This includes anything living or recently dead, such as trees, plants, and algae. When burned, biomass releases the same amount of carbon dioxide as if it were decomposing naturally.

However, since it is a renewable resource, it is considered a more sustainable option than fossil fuels. Additionally, when used in conjunction with other green technologies, such as solar panels or wind turbines, biomass can help create a truly renewable energy system.

The benefits of biomass

renewable energy source

  • Biomass is a renewable energy source that we can quickly replenish.
  • Burning plant matter releases carbon dioxide, which is offset by the carbon dioxide absorbed by plants as they grow. As a result, biomass is considered a carbon neutral energy source.
  • It is (somewhat) carbon neutral, meaning it does not release additional greenhouse gases into the atmosphere.
  • We can use it to generate electricity, heat and transportation fuels.
  • Biomass power plants are relatively efficient and have low emissions. (But only if done right). These power plants have been built in many countries around the world, providing a reliable source of renewable energy.
  • Biomass can be grown on marginal land, making it an ideal energy source for rural communities.
  • Biomass-based energy industries create jobs and help boost local economies.
  • Biomass can create biofuels, which can be used in transportation applications such as cars and planes. Biofuels produce fewer emissions than fossil fuels, which makes them environmentally friendly.
  • It is versatile and easily obtained from many types of plants and organic waste. This makes it an ideal renewable energy source, easily adaptable to specific needs and geographical areas.


Although biomass is often promoted as a renewable and environmentally friendly source of energy, it has several disadvantages that we must take into account.

One of the biggest criticisms is its potential to contribute to air pollution. When burned, biomass releases particles and other pollutants into the atmosphere. These pollutants can harm human health, especially for people with respiratory diseases such as asthma.

Additionally, burning plant matter releases harmful chemicals such as mercury and carbon dioxide.

Biomass is also a low energy density. This means that a large amount of biomass is needed to generate a small amount of energy. For example, while Europe’s biomass power plants produce less than 2% of the EU’s electricity needs, they are consuming forests at an unprecedented rate.

This can make it impractical or even impossible to use in some situations.

Finally, biomass is also a relatively inefficient source of energy. A significant part of the energy content of biomass is lost when it is converted into electricity or other forms of energy. For these reasons, it is crucial to consider the advantages and disadvantages of biomass before investing in this technology.

The promise of biofuels

Biofuels are renewable fuels made from living organisms or their by-products. The most common type of biofuel is ethanol, made from corn, sugar cane or other plant material.

Biofuels generally burn cleaner than fossil fuels like gasoline and diesel, and we can use them in existing engines with little or no modification. Additionally, biofuels are often produced locally, reducing dependence on imported oil.

However, biofuels also have some disadvantages. They can be more expensive than fossil fuels and their production can strain local food supplies. Overall, biofuels offer a promising alternative to fossil fuels, but their feasibility will ultimately depend on technological advances and policy changes.

Weaning ourselves off fossil fuels will require leaps of imagination and massive investments in the research and development of sustainable fuels. Biofuels hold great promise, as the documentary below shows:


Biomass holds great promise as a sustainable energy source. It is renewable, carbon neutral and can generate electricity, heat homes and businesses and power transportation. With proper management, it can provide a reliable, clean source of energy with minimal environmental impact.
