Analysis on Employment Effects of the Introduction of Renewable Energy Technologies Using an Extended Input-output Table

Abstract

The present study aims to compile an extended input-output table to analyze employment effects of the introduction of solar photovoltaic (PV) and wind power generation technologies. Based on 2005 input-output table for Japan, the extended input-output table is constructed by creating new sectors related to the two above generation technologies and adding direct employment requirements in all the sectors. The extended input-output table allows for estimating direct and indirect employment required over the life cycle (manufacturing, construction, and operation & maintenance) of PV and wind power generation technologies. Using the extended table, life cycle employments induced by the introduction of PV and wind power generation technologies are estimated to be 2.8 and 0.69 person/GWh, respectively. Also, about 30% and 35% of life cycle employments for PV and wind power are roughly generated overseas, respectively.
