市区町村別のバイオマスエネルギーのポテンシャル評価

抄録

Objective. The objective of this research is to perform potential evaluations of the biomass energy of all municipalities from Japan by using the same methodology. After comparing with other renewable energy, it aims to grasp the use of aptitude, according to geographic division. The calculation of the annual amount of potential evaluations was considered as the year 2010 or the most recent year, and it was calculated to be 1,711 municipalities as of 2010.
Results and Conclusions. Out of all the renewable energy, heat usage of the biomass of an agricultural production system has the 2nd largest amount of potential and the biomass of a forest-product system has the 4th largest amount of potential, which is greater than sunlight. Also, if the field of cost is disregarded, it is required to promote exploitation of energy of the biomass in a country’s policy when controlling fossil fuel and nuclear power plants. Moreover, if assumed that the introductory cost is proportional to the amount of potential per area, the local government should promote more introductions and a flat-ground agricultural area in the municipalities belonging to 6th area, which is Okinawa Prefecture. However, since the forest area has a high potential in large cities and in municipalities of Tokyo, it should promote policies even in metropolis areas.
