What Drives Bioenergy Growth? Key Factors and Influences

Bioenergy – energy derived from organic materials like agricultural residues, dedicated energy crops, and organic waste – has moved from a niche concept to a central pillar of the global clean energy transition. Today it accounts for more than half of the world’s renewable energy supply. But what exactly is pushing governments, industries, and communities toward it? The answer lies in a combination of urgent climate pressures, strategic energy concerns, technological breakthroughs, and international policy frameworks that together create a powerful set of drivers for bioenergy growth.

The shift towards bioenergy

Three interconnected forces are most responsible for the global turn to bioenergy: climate change, energy security, and fossil fuel depletion.

Climate change as the primary catalyst

The scientific consensus is clear – greenhouse gas (GHG) emissions from burning fossil fuels are the primary driver of global warming. Bioenergy offers a pathway to displace coal, oil, and natural gas across multiple sectors including transport, power generation, and heating. When biomass is burned or converted to fuel, the carbon released was recently absorbed from the atmosphere by the plant material, making the net emissions significantly lower than burning fossil fuels. According to research published in Frontiers, societal concerns about climate change are among the most significant drivers of the global bioenergy economy. Advanced technologies like Bioenergy with Carbon Capture and Storage (BECCS) go even further – by capturing CO₂ produced during bioenergy generation and storing it underground, BECCS can achieve net-negative emissions, making it a critical tool for meeting the 1.5°C climate target outlined in the Paris Agreement.

Energy security and fossil fuel depletion

Fossil fuels are finite. Global reserves of oil and natural gas are being depleted at a rate far exceeding natural replenishment, and the geopolitical fragility of fossil fuel supply chains has been repeatedly exposed – most recently during the COVID-19 pandemic, when supply disruptions caused severe energy price spikes. The IEA Bioenergy 2023 report notes that energy security has re-emerged as a critical global concern, and that bioenergy can improve national resilience by providing regionally sourced, renewable energy. Countries that invest in local biomass resources reduce their dependence on imported fuels, insulating their economies from volatile international energy markets. According to research in Frontiers Energy Research, energy security and climate change mitigation are consistently cited by nearly all nations as the two most significant motivations for developing national bioenergy strategies.

Technological advancements driving viability

Bioenergy’s growth is not just demand-driven – it is also being enabled by rapid advances in conversion technology. Understanding the generational evolution of biofuels helps explain why the sector is becoming more sustainable and scalable.

From first-generation to advanced biofuels

First-generation biofuels are produced from edible crops such as corn, sugarcane, and soybeans. While effective at producing ethanol and biodiesel, they raise legitimate concerns about competition with food supply and land use. This prompted the development of second-generation biofuels, which use non-food feedstocks like agricultural waste, forestry residues, and dedicated energy crops such as switchgrass and miscanthus. These inputs don’t compete with food production and can often be grown on marginal land unsuitable for crops. UNCTAD has highlighted that second-generation biofuels – particularly cellulosic ethanol – are an important instrument for developing countries to meet their climate commitments while diversifying their economies.

Third and fourth-generation biofuels push the boundary further. Third-generation systems use algae as a feedstock – organisms that are highly productive, require no agricultural land, and can capture CO₂ from industrial emissions. As research linked to COP21 targets shows, algae-based biofuels can achieve a zero or even negative net carbon balance. Fourth-generation biofuels involve engineering photosynthetic microorganisms to directly produce fuels, pushing efficiency boundaries well beyond what conventional crops can achieve.

BECCS and the net-negative frontier

One of the most significant technological developments is the integration of bioenergy with carbon capture and storage. BECCS systems generate energy from biomass combustion while simultaneously capturing the resulting CO₂ before it enters the atmosphere. Experts responding to the Paris Agreement noted that technologies like BECCS could allow carbon dioxide to be effectively removed from the atmosphere – achieving “negative emissions” that go beyond simply reducing current output. This positions BECCS as a critical technology in climate scenarios that aim to overshoot and then correct the 1.5°C warming threshold.

Economic and environmental impacts

Bioenergy’s growth is also supported by compelling economic arguments, particularly at the local and national level.

Reducing fossil fuel dependency

Countries that invest in domestic bioenergy infrastructure reduce their import bills for oil and natural gas. This keeps energy spending circulating within the national economy rather than flowing abroad. The U.S. Department of Energy estimates that developing domestic biomass resources could contribute nearly $259 billion and over 1.1 million jobs to the American economy by 2030 – jobs that cannot be outsourced and span agriculture, manufacturing, scientific research, and operations. The ScienceDirect review on biofuels and SDGs confirms that the ease of production and storage, high energy density, and compatibility with existing fuel infrastructure are key practical advantages that help biofuels gain market traction over fossil alternatives.

Supporting local economies and rural development

One of bioenergy’s most distinctive economic advantages is its geographic profile. Unlike offshore oil drilling or centralized power plants, biomass feedstock production and processing happens mostly in rural areas, where economic opportunities are often scarce. Research on bioenergy’s socio-economic benefits confirms that bioenergy projects create jobs across the full supply chain – from planting and harvesting feedstock to operating processing facilities and maintaining equipment. Brazil’s sugarcane biofuel industry is a strong example: it has created large-scale rural employment while making Brazil one of the world’s leading biofuel exporters. Similarly, Sweden has used forest residues to generate heat and electricity, cutting fossil fuel use while generating rural income. Frontiers research highlights that biofuels also help alleviate energy poverty and can serve as a lower-cost alternative to expensive imported energy, particularly benefiting rural and developing-country populations.

Beyond jobs, bioenergy supports the diversification of rural economies. Communities that rely on a single agricultural commodity gain a second revenue stream when crop residues, animal waste, or energy crops can be sold into the bioenergy supply chain. This economic resilience is especially valuable in regions vulnerable to commodity price fluctuations.

Environmental co-benefits

Properly managed bioenergy also delivers broader environmental gains. Growing energy crops on degraded or marginal land can restore soil health and biodiversity. Biogas systems that capture methane from livestock or food waste prevent a potent greenhouse gas from entering the atmosphere. And according to the U.S. Department of Energy’s assessment of the SCOPE Bioenergy Report, informed management of bioenergy crops can actually reduce factors contributing to food insecurity, promote biodiversity, and restore productivity to degraded land – countering the common assumption that bioenergy always competes with food production.

Policy and global agreements

Without supportive policy frameworks, bioenergy would struggle to compete financially with heavily subsidized fossil fuels. Global climate summits have played a defining role in accelerating investment and adoption.

COP21 and the Paris Agreement (2015)

The 2015 UN Climate Change Conference in Paris – COP21 – was a turning point for renewable energy globally. At COP21, countries agreed to limit global temperature rise to well below 2°C above pre-industrial levels, with efforts to cap it at 1.5°C. The Paris Agreement’s targets placed renewable energy – including biofuels from non-edible feedstocks – squarely at the center of national decarbonization strategies, particularly for the transport sector, where liquid biofuels are among the most practical low-carbon alternatives. Nations were required to submit Nationally Determined Contributions (NDCs) – country-level climate plans – and bioenergy featured prominently in the NDCs of many agricultural and forested nations. The Paris Agreement also acknowledged BECCS as a potential pathway to achieving net-negative emissions, spurring research investment globally.

COP26 and the Glasgow Climate Pact (2021)

If COP21 set the ambition, COP26 in Glasgow in 2021 focused on implementation. Decarbonization commitments deepened significantly, with 64 governments pledging net-zero emissions targets. To achieve these pledges, technologies like BECCS would need to scale dramatically, requiring hundreds of millions of tonnes of CO₂ captured annually by 2030. COP26’s transport day placed particular focus on aviation and heavy freight – sectors that cannot easily electrify and where biofuels are the leading low-carbon option. The UK government issued a dedicated Biomass Policy Statement at COP26, formally recognizing bioenergy’s role in national climate delivery. Investment commitments followed: major energy funds explicitly listed advanced biofuels as part of their clean energy portfolios alongside wind and solar. The overall signal from Glasgow was clear – bioenergy was no longer a fringe option but an integral component of the mainstream clean energy transition.

The role of mandates and support policies

Beyond summits, national governments have implemented concrete policy instruments to drive bioenergy adoption. Research on bioenergy in developing nations confirms that bioenergy markets are primarily policy-dependent – since biofuel production is often not yet cost-competitive with fossil fuels without support. Instruments such as blending mandates (requiring a percentage of biofuel in transport fuels), feed-in tariffs, tax incentives for biomass power plants, and public R&D funding have all been critical in building the industry to a scale where market forces can increasingly take over. The EU’s Renewable Energy Directive, the US Renewable Fuel Standard, and India’s National Biofuel Policy are examples of frameworks that have catalyzed domestic bioenergy industries in their respective regions.

Putting it all together

Bioenergy’s growth is not driven by any single factor. Research mapping bioenergy’s contributions to the UN Sustainable Development Goals shows that the sector touches affordable and clean energy (SDG 7), climate action (SDG 13), economic growth and decent work (SDG 8), and reduced inequalities (SDG 10) simultaneously. That multi-dimensional impact is precisely why policymakers, investors, and communities around the world are pursuing it. The convergence of climate urgency, technology readiness, economic incentives, and international policy commitment has created conditions where bioenergy can transition from supplementary to essential – provided it is governed sustainably and transparently. The challenge ahead is not whether to develop bioenergy, but how to do so in ways that genuinely serve people, ecosystems, and the climate together.

What do you think? As nations scale up bioenergy to meet their climate commitments, how should policymakers balance the economic benefits to rural communities against potential risks to food security and land use? And do you think advanced technologies like BECCS can realistically be deployed at the scale needed to meet net-zero targets within the next few decades?
