Survey Overview and Purpose This survey was conducted as a FY2024 METI commissioned project to verify the effectiveness of Japan's renewable energy introduction promotion measures and examine future development policies. It comprehensively analyzes the progress and challenges of policies toward achieving carbon neutrality by 2050.
Renewable Energy Introduction Results Total renewable energy generation in FY2024 increased by 13.7% compared to the previous year, with the share of total power generation reaching 23.1%. Solar power showed particularly strong growth at 18.2%, while wind power achieved 15.4% growth, demonstrating steady expansion.
Regional Deployment Status and Characteristics Regional analysis reveals that renewable energy penetration rates vary significantly by region, with island areas and rural regions showing higher adoption rates. Local government support policies and community acceptance levels are identified as key factors influencing deployment success.
Economic and Social Impact Assessment The renewable energy sector contributed approximately 890,000 jobs and ¥15.7 trillion in economic impact. Rural area revitalization effects through renewable energy projects are particularly noteworthy, creating new employment opportunities and tax revenue sources.
Technical and System Challenges Key challenges include grid stabilization due to output fluctuations, storage technology development needs, and grid infrastructure reinforcement requirements. The survey analyzes solutions for each challenge and presents specific technical development directions.
Policy Enhancement Recommendations Recommendations include strengthening feed-in tariff systems, promoting energy storage technology, enhancing grid infrastructure, and improving regulatory frameworks. The report presents comprehensive policy packages for accelerating renewable energy deployment toward 2030 targets.
