Expanding renewable energy installations is not only driven by the policy goal of net-zero emissions but also serves as a key measure to reduce the risks associated with high dependence on imported energy. As Taiwan's demand for renewable energy installations increases, the environmental impact of these installations has become a focus of public concern. Therefore, the goal of this research project is to establish a framework for the environmental cost-benefit assessment of renewable energy installations. The preliminary work focuses on evaluating the environmental cost analysis of various renewable energy types, prioritizing key categories for detailed assessment, and developing an assessment framework for secondary categories to be used for future site-specific analyses.
This project has been implemented according to the progress plan, completed the established work progress, and submitted an outcome report accordingly. First, the prioritization of renewable energy types for cost-benefit analysis was completed. Based on the conclusions from the first work discussion meeting, solar power has been selected as the primary focus for analysis, with wind power as the secondary focus. Second, a comprehensive review was conducted, gathering and assessing environmental impact assessments and environmental cost-benefit analysis items related to the selected categories. This review drew on academic literature, national regulations, evaluation standards, and case studies. After analyzing the collected materials, the research team concluded that using a life cycle assessment framework combined with non-market value evaluation methods is the most appropriate approach for this project’s evaluation.
Finally, a listing of the environmental costs and benefits at each life cycle stage for solar photovoltaic and wind power systems was compiled. For each item, available monetized indicators were collected. A case study on solar power was conducted to quantify the environmental costs and benefits, providing a monetary evaluation that offers specific results for policy reference.
