The analysis focuses on energy consumption, operational costs, and carbon emissions of both systems to determine the feasibility and sustainability of transitioning from GHP to EHP. Simulation models applied to public and general facilities assess electricity demand changes, with an emphasis on peak power demand scenarios. Simulation results indicate that while transitioning the total installed capacity of GHPs in South Korea to EHPs increases electricity consumption by approximately 398.8 MW, the impact on the power grid remains minimal due to South Korea’s increasing renewable energy share.

The research findings reveal that the accelerated energy transition not only creates numerous employment opportunities but also significantly expands provincial employment levels. Furthermore, heterogeneity analyses demonstrate that provinces with higher GDP level, moderate to limited renewable energy resources, and higher employment levels—such as the developed eastern coastal provinces and certain central regions—experience a more pronounced contribution of the energy transition to employment growth. Meanwhile, policy intervention will unleash the employment effect of energy transition in high-carbon regions.

However, costs and emissions associated with the long-distance transport of renewable energy carriers may incentivize the relocation of steel production closer to renewable energy sources. This “green relocation” would affect regional economic structures and global trade patterns. Nevertheless, the macroeconomic and environmental impacts of alternative industry location options remain underexplored. This study compares the impacts on value-added, prices, and emissions under two options for decarbonizing the Dutch steel industry: importing green hydrogen from Brazil to produce green steel in the Netherlands versus relocating production to Brazil and transporting green steel to the Netherlands. Impacts are analyzed by combining a price and a quantity model within an environmentally extended multiregional input-output (EE-MRIO) framework. Results suggest that the relocation option brings the greatest synergies between climate and economic goals at the global level, as it leads to lower production costs, smaller price effects, and greater emissions reductions. However, relocation also results in stronger distributive impacts across global regions. Higher carbon prices would be insufficient to counteract relocation incentives. This calls for policymakers in industrialized countries to systematically consider the possibility of green relocation when designing decarbonization and industrial competitiveness strategies.</div></div>","PeriodicalId":11672,"journal":{"name":"Energy Policy","volume":"206 ","pages":"Article 114726"},"PeriodicalIF":9.3,"publicationDate":"2025-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144365085","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
