DESIGN OF THE SUSTAINABLE ENERGY SYSTEM IN A LOCAL AREA CONSIDERING ECONOMIC AND RESOURCE CIRCULATION

Abstract

 In Japan, fossil fuels imported supply about 90% of primary energy, which occurring large amount of CO₂ emission and outflow of domestic funds to other coutries. The objective of this study is to design the local energy system using local resources which can realize low emission and economic circulation in the area. The targeted area is Fukushima prefecture. First, the amount of energy resources in local area is estimated using GIS. Second, the energy system is optimized in terms of CO₂ emission and cost, then the system is evaluated from multi points of view which are economic effect, energy efficiency and resource diversity. As a result, it is concluded that if more wind energy and wood biomass used the CO₂ emissions will be decreased to almost 0 and economic ripple effect in the local area will be increased.
