Economic Contributions and Green Job Implications of Japan’s Energy Transition: An Integrated Assessment of Decarbonization Scenarios in Kyushu Region

This study examines the economic and employment impacts of renewable energy systems (RES) in Kyushu, Japan, focusing on solar, wind, and biomass power. Using the Leontief input-output model, the research quantifies job creation and economic contributions from renewable energy investments. Employment coefficients highlight indirect, construction, and operational job impacts. Biomass power, with its extensive supply chain, is the largest contributor to job creation and economic output, generating 7,736 jobs and 32.4 million JPY annually. Wind power follows, with significant contributions from moderate operational demands, creating 1,824 jobs and adding 3 million JPY to the economy. Solar power, despite its efficiency, generates fewer jobs and economic impact due to minimal maintenance requirements, contributing 348 jobs and 1.2 million JPY. The study underscores the multifaceted benefits of renewable energy, emphasizing broader socio- economic impacts beyond energy output. The findings highlight the importance of integrating renewable energy investments with economic development strategies, illustrating how such initiatives can drive GDP growth, industrial expansion, and energy security, advancing sustainable economic growth and decarbonization goals in Kyushu.
