Description

While forests occupy about 70% of Japanʼs land area, forestry is in a difficult situation for economic independence in many areas. As a result, the social and environmental impacts caused by the decline of forestry, such as forest devastation due to the decrease in the number of bearers, are enormous. Therefore, there is a high social demand for regional revitalization by utilizing forest resources, and in particular, the demand for woody biomass as a carbon-neutral energy resource for local production and consumption is increasing. In this paper, we target Yamagata Prefecture, where both the accumulated amount of woody biomass and the production cost are close to the average of Japan, and the energy consumption (power consumption) of the household sector, which reflects the population size, is compared with the supply capacity when woody biomass is used as an energy resource. Then we report the results of analysis on the optimum location and scale of biomass power plants. As a result, it was quantitatively clarified that the number and the scale of the present biomass power plants are far from sustainable supply compared to the amount of woody biomass resources.
