Abstract The availability of energy resources and their relationship with global biodiversity are critical concerns that demand urgent attention, especially given the world’s rising energy demands. This review paper examines the impacts of both renewable and non-renewable energy sources on biodiversity across different ecosystems. The extraction and use of fossil fuels—coal, oil, and natural gas—have led to severe pollution, habitat destruction, and climate change, threatening countless species and ecosystems. The processing and consumption of these non-renewable resources continue to accelerate biodiversity loss. While renewable energy sources—such as solar, wind, bioenergy, and hydropower—offer a pathway to reducing greenhouse gas emissions, they also pose biodiversity challenges. Large-scale solar farms alter land use, causing habitat fragmentation. Wind farms, while crucial for clean energy, threaten bird and bat populations. Hydropower projects disrupt river ecosystems, affecting aquatic species’ migration patterns. Similarly, bioenergy production often relies on extensive monoculture farming, leading to deforestation, agrobiodiversity loss, and competition with food crops. This paper explores mitigation strategies, emphasizing ecological offsets and habitat restoration as key conservation tools. These approaches align with global frameworks such as the United Nations Sustainable Development Goals (SDGs), ensuring that energy policies integrate biodiversity protection. The review highlights the importance of balancing energy expansion with environmental sustainability through strategic policymaking. A region-specific approach is essential, given the varying energy needs and ecological sensitivities across countries. Overreliance on energy-intensive technologies in some regions exacerbates environmental degradation, necessitating countermeasures to prevent resource overexploitation. By incorporating biodiversity-conscious energy strategies into decision-making, it is possible to achieve a sustainable balance between energy production and conservation. This analysis underscores the need for globally coordinated yet locally adaptive policies to ensure that the transition to renewable energy does not come at the expense of biodiversity.
