REvision2026: 15 Years of Global Energy Transition and Future Outlook for Japan
11 March 2026
Renewable energy-based electricity is now the most cost competitive power option, supplying more than half of electricity generation in many countries around the world. A dramatic scaling up of renewable energy capacity is urgently needed to avoid the already extensive and accelerating impacts of the climate crisis. To realize this in Japan, it is necessary to raise the national target for renewables, remove the constraints related to grid access and revise old outdated inefficient regulations that hinder the effective integration of renewables. Renewable Energy Institute helps to solve these issues and other challenges by conducting studies in electricity systems, electricity grids, renewable energy policies, market environments and makes proactive policy proposals to accelerate decarbonization in Japan.
