Abstract

An input-output table for the analysis of a next-generation energy system (IONGES) was created. This IONGES effort incorporates renewable-energy sectors into the 2011 input-output table published by the Ministry of Internal Affairs and Communications, Japan. The sectors incorporated in the IONGES data cover power generation facility construction sectors and power generation sectors for 15 types of renewable energy. The IONGES data consist of the following two types of table: a table incorporating renewable-energy sectors as they existed in 2011 (2011 IONGES) and a table incorporating renewable-energy sectors up to the composition ratio assumed in 2030 (2030 IONGES). The assumption of the power supply composition ratio for 2030 IONGES was based on the long-term energy supply-demand outlook prepared by the Ministry of Economy, Trade and Industry, Japan. For the IONGES effort, special attention was paid to the following points. First, we created equipment sectors for solar and wind power generation. Second, we divided the biomass power sectors in detail (eight divisions) according to their roles and described the relationship between the biomass power generation sectors and sectors supplying fuel to them. IONGES was used to compare the input structure of each renewable-energy sector and each supply chain brought about by it. The ripple effect of the supply chain on entire economy was also visualized as a "unit structure." IONGES can make it possible to verify new input-output structures by using renewable energy.
