Biogas Costs Surpassed Wind and Solar Power Expenses
Research suggests shifting biogas resources toward waste management instead of energy production for better efficiency.

Should the government prioritize funding for the most cost-effective renewable energy sources?
A 2026 analysis found that biogas costs remain high due to feedstock procurement, even as wind and solar costs fell by 70% to 90% over the last decade. This comparison highlights a significant economic shift for renewable energy strategies.
Why it matters
The high cost of biogas energy compared to other renewables suggests that current funding models for these projects may be unsustainable. Moving focus toward waste management could better leverage anaerobic digestion's ability to reduce pathogens and emissions.
A 2026 analysis compared the levelized cost of energy for biogas against wind and solar in Germany. While wind and solar costs dropped significantly over the past decade, biogas costs remained stagnant, with high expenses driven by continuous feedstock sourcing.

The details
Biogas production relies on constant inputs, making it more expensive than wind or solar, which largely incur costs only during initial construction. Because biodigester installation accounts for 20% to 40% of production costs, plants often require external subsidies to stay viable. Experts suggest shifting toward using anaerobic digestion for manure management, which inactivates 99% of pathogens and could mitigate 1,000 million tonnes of carbon dioxide equivalent.
Timeline
2021-2023: European Union renewable energy subsidies fell from 83 billion to 61 billion euros.
2024: Biogas and renewable energy cost data were recorded in Germany.
2026: Engineering Environment published the research perspective.
Health Landscape
The study sits within the broader context of European Union renewable energy subsidies, which dropped from 83 billion to 61 billion euros between 2021 and 2023. This trend necessitates moving away from crop-intensive biogas models toward more efficient waste-to-energy applications.
This shift in renewable energy strategy highlights the importance of sustainable waste management in protecting public health, particularly regarding pathogen control in livestock manure. While this is a high-level policy concern, the efficacy of anaerobic digestion in mitigating waste-related health risks is worth monitoring.
The takeaway
Energy economics are shifting away from crop-based biogas as wind and solar power continue to decrease in price. Policy conversations should emphasize the value of using anaerobic digestion for waste-based pathogen mitigation rather than primary energy generation.
