Iida Tetsunari is a pioneering advocate for renewable energy and sustainable policy, dedicated to transforming Japan’s energy landscape. As the founder of the Institute for Sustainable Energy Policy (ISEP), he has played a key role in promoting clean energy solutions and community-driven approaches to energy independence. After witnessing the vulnerabilities of centralized energy systems, particularly in the wake of the Fukushima nuclear disaster, Iida became a leading voice for transitioning to decentralized, renewable energy sources. Under his leadership, ISEP has worked to empower local communities, advance energy efficiency, and influence policy changes that prioritize sustainability. For Iida, the work is about more than energy—it’s about creating a resilient, equitable future where communities have control over their resources and can thrive in harmony with the environment.
