Abstract:

Background & Aims: In recent years, China’s rapid expansion of photovoltaics (PVs) and wind power capacity has triggered attention and discussions on their ecological issues. Effective mitigation measures and tools are urgently needed but remain underutilized. This study reviews domestic and international mitigation measures based on the ecological impacts of onshore centralized PVs and wind power plants.

Review results: Our findings indicate that early site planning is the most effective and cost-efficient approach to avoiding adverse impacts. From a landscape perspective, key planning methods for mitigating ecological impacts include the environmental and social impact assessment (ESIA) and sensitivity mapping for risk screening, the Development by Design (DbD), combination of spatial planning and sensitivity mapping, and compatibility assessments between renewable energy and biological resources for integrated spatial planning. These methods help guide the renewable energy siting process based on ecological impacts and risks.

Recommendations: We propose five priorities for improving site selection and mitigation of ecological impacts in China: (1) Enhancing research on ecological impacts of PVs and wind power plants, focusing on endangered and sensitive species and their habitats, and developing mitigation strategies; (2) Simplifying siting methods and decision-making tools, and training professionals for effective implementation; (3) Strengthening cross-sector coordination to align land-use planning with solar and wind power development, and optimizing tools for ecological-friendly site selection for renewable energy projects, particularly in repurposing areas like abandoned mines. New projects must incorporate mitigation measures into design before construction; (4) Establishing a continuous ecological impact monitoring system to assess and adapt mitigation measures over time; (5) Strengthening policy support for ecological-friendly wind and solar development, by issuing technical guidelines and standards for ecological conservation and restoration. Policies should be adapted to local conditions, avoiding “one-size-fits-all” approach, and promoting innovative, eco-friendly renewable energy development models.
