Why Is Biomass Important To The World?

Biomass refers to organic matter that comes from plants and animals. It includes wood, plants, agricultural waste, and manure. Biomass contains stored energy from the sun, which can be converted into other forms of renewable energy and fuels when needed. Biomass is considered a renewable resource because we can continue growing plants and producing biomass as long as the sun shines.

Biomass is important because it can provide clean energy, reduce dependence on fossil fuels, lower greenhouse gas emissions, and create economic opportunities in the emerging bioeconomy. As the world looks to transition to renewable energy sources, biomass has the potential to supply a significant portion of our power, heating, and transportation fuel needs sustainably into the future.

Renewable Energy Source

Biomass is an important renewable energy source that can help reduce dependence on fossil fuels. Unlike coal, oil, and natural gas which take millions of years to form, biomass can be produced on a short timescale. Biomass refers to any organic matter that comes from plants or animals and can be used as an energy source. This includes wood, crops, seaweed, manure, and organic waste. Biomass contains stored chemical energy from the sun. When burned, the chemical energy is released as heat that can be used to generate electricity or provide heating.

Burning biomass directly, or converting it into liquids or gases to generate electricity and heat, provides a renewable energy source. Energy can be generated from biomass with lower net carbon emissions compared to fossil fuels. While burning biomass does release carbon dioxide, the plants that biomass comes from absorb carbon dioxide as they grow. This makes biomass a carbon-neutral energy source in theory, although there are debates around how carbon-neutral different biomass sources really are in practice. Still, sustainably produced biomass has an important role to play in the transition to renewable energy.

Reduces Dependency on Fossil Fuels

One of the main advantages of using biomass energy is that it reduces reliance on fossil fuels such as coal, oil, and natural gas. Fossil fuels are non-renewable, meaning they take millions of years to form and the global supply is finite. The world’s energy consumption is still predominantly fueled by fossil fuels like petroleum, coal and natural gas. However, as these finite resources deplete and dwindle in quantity, there is pressure to develop alternative renewable sources of energy. The more we use biomass as an energy source, the less we need to depend on fossil fuels for our energy needs. A transition to renewable biomass can help prolong the lifetime of our remaining fossil fuel reserves.

biomass offers a renewable energy source that can help transition away from fossil fuels.

Biomass already supplies about 3% of the energy used in the United States. With advanced technologies and scaling up of operations, biomass has the potential to replace a substantial portion of fossil fuel usage. For example, biogas generated from organic wastes can replace natural gas for heating and electricity generation. Fuels like ethanol and biodiesel, which are derived from crops like corn and soybeans, can directly substitute transportation fuels like gasoline and diesel. Using biomass reduces the pressure on fossil fuel supplies and contributes toward energy independence and sustainability.

Lower Greenhouse Gas Emissions

Using biomass as an energy source results in lower greenhouse gas emissions compared to fossil fuels like coal, oil, and natural gas. This is because the carbon dioxide released when biomass is burned is offset by the carbon dioxide absorbed as plants grow. Unlike fossil fuels, which release carbon dioxide that has been locked underground for millions of years, the carbon in biomass is part of the natural carbon cycle.

The Intergovernmental Panel on Climate Change has identified replacing fossil fuels with biomass as an effective strategy for mitigating climate change. When biomass is used as a fuel source, it can reduce carbon dioxide emissions by up to 90% compared to coal and by around 80% compared to natural gas. In addition, biomass only emits the amount of carbon it absorbed while it was growing, resulting in no net addition of carbon to the atmosphere. This makes biomass an important tool to reduce greenhouse gas emissions and limit global warming.

Waste Reduction

Biomass utilizes agricultural, forest, urban and industrial waste materials.

Agricultural waste products like corn husks, sugarcane bagasse, and coconut shells can be converted into energy instead of being left to decompose. This prevents methane emissions and makes use of material that would otherwise go to waste.

Forestry waste in the form of dead trees, fallen branches, sawmill scraps, and excess harvesting from logging can provide biomass feedstock. Using these materials creates an outlet for forestry waste.

Urban waste like municipal solid waste, food waste, sewage, and landfill gas can also serve as biomass sources. Diverting urban waste to energy production reduces landfill growth.

Industrial waste such as black liquor from paper manufacturing, distillery residues, and wood manufacturing waste represent additional forms of unused biomass. Transforming industrial leftovers into fuel decreases waste and repurposes these materials.

Overall, biomass energy transforms would-be pollution into productive energy, simultaneously improving waste management and fuel resources.

Economic Benefits

Biomass production provides significant economic benefits, especially for rural and agricultural communities. Growing biomass crops and converting waste into energy creates jobs in planting, harvesting, transportation, and processing. Biorefineries that produce biofuels and biochemicals employ people in construction, engineering, operations, and maintenance. Many of these opportunities are located in rural areas, providing much-needed employment and stemming the flow of economic emigration to cities. The biomass supply chain also creates demand for equipment, logistics, and other services, generating additional jobs and revenue. With the right policies and incentives, biomass production can help revitalize struggling rural economies by creating stable local markets and keeping money circulating within communities. In an increasingly decentralized and distributed energy system, biomass offers opportunities for farmers, landowners, and rural communities to gain energy independence and strengthen their economic resilience.

Improved Soil Quality

Growing biomass crops can help improve depleted soil and land that can no longer support food agriculture. By rotating biomass crops such as switchgrass or fast-growing trees, nutrients can be returned to the soil. These crops have roots that reach deep into the ground, reducing soil compaction. The extensive root system of perennial bioenergy crops also helps reduce runoff and erosion. Additionally, perennial bioenergy crops require fewer chemical inputs than annual row crops, which helps improve soil health over time. As soil conditions improve, the land can eventually be restored to support food crop production again. Thus, strategic use of biomass crops can play an important role in restoring marginal agricultural land and improving long-term soil quality.

Sustainable Agriculture

The demand for biomass has driven the adoption of more sustainable agriculture practices. Since biomass relies on biological material from plants and animals to produce energy, many farms are now prioritizing agricultural methods that regenerate and protect natural resources.

For instance, some farmers are implementing crop rotations, cover cropping, and conservation tillage to preserve soil nutrients and prevent erosion. Many livestock farms are now managing manure in ways that reduce impacts on water and air quality. Overall, biomass production encourages smart land management and responsible stewardship of agricultural resources.

With the biomass industry expected to expand, agricultural regions have strong incentives to adopt eco-friendly practices that enable long-term productivity. Biomass can play a key role in transitioning farming operations to be more sustainable and environmentally sound over the long-term.


While biomass offers many benefits, it also comes with some drawbacks and limitations:

High Costs – The production and infrastructure for biomass energy often requires major upfront costs, including investments in bioenergy plants and the logistics of obtaining and transporting bulky biomass sources. This can make biomass less financially viable than other renewables like solar and wind.

Land Usage – Large-scale biomass production requires significant amounts of land to grow energy crops, which has raised concerns about disrupting food supply and deforestation. There are debates about whether biomass truly makes the most productive and sustainable use of agricultural lands.

Low Energy Density – Biomass generally has a lower energy density compared to fossil fuels, so it is bulkier and requires more storage space. Transporting and handling large volumes of biomass feedstock can add to costs.

Emissions – While biomass emits less net carbon than coal, its combustion and harvesting processes still produce some greenhouse gases and air pollutants that impact the environment.

Supply Risks – Since biomass depends on plant or waste matter for feedstock, inconsistent growing conditions like droughts or crop failures can disrupt supply. This supply volatility makes it challenging for biomass to serve as a reliable baseload power source.


In summary, biomass plays an integral role as a renewable energy source that can help reduce our dependence on fossil fuels. Widespread adoption of biomass has the potential to lower greenhouse gas emissions and waste while providing economic benefits. When sustainably produced, biomass can improve soil quality and support agricultural systems. However, scaling up biomass does face challenges around land use and ensuring sustainable practices. Overall, biomass serves as an important renewable resource that can contribute to a more sustainable future when utilized responsibly.
