Assessment of the impacts of willingness to pay on diffusion of renewable energy resources in Japan

摘要

The aim of this study is to analyze and assess the impacts of the citizens'willingness to pay on future diffusion of renewable energy resources in prefectures of Japan.Electricity production by renewable energy resources such as solar photovoltaic and wind power is an effective measure to mitigate climate change by reducing carbon dioxide emissions as well as to avoid depletion of fossil-fuel resources.Although its higher capital cost of renewable energy than those for conventional fossil fuel energy resources,there is a movement to defray the additional cost of electricity generated by renewable energy resources,further affecting the diffusion of renewable energy.For the purpose,we have developed series of models to estimate the willingness to pay and the corresponding acceptability for renewable energy resources.The model was designed to be incorporated into a multi-regional optimal generation planning model to determine the optimal energy roadmap.
