Korean thermal power has had a prominent position in energy policies for the past decades. However, pollutants from the combustion of fossil fuels used in converting thermal energy into electrical energy have undesirable effect on the environment. This paper applies fuzzy set theory (FST) to identifying the significance of various environmental impacts using a specific case study of the electric power utilities in Korea. To this end, we consider nine environmental impacts: mortality, morbidity, forest, agricultural production, materials, visibility, thermal discharge water, landscape, and global warming. A survey of randomly sampled 1,000 households was administrated to obtain value judgments from FST about the environmental impacts of a thermal power plant. The overall results show that global warming is the most important attribute in environmental effect-related decision-making processes and followed by morbidity and mortality in order. The implications of the results for electric power utilities are also discussed. We found that the work and results can provide valuable insights for major decision making in energy and environmental planning of the electric power utilities.
