Iida started his career as a nuclear engineer, but he quit in 1992, and went to study renewable energy in Sweden. When he returned to Japan in 1998, he formed the Institute for Sustainable Energy Policies. Since then he has set up several green mutual funds. In September 2011, Iida launched the Japan Renewable Energy Foundation, which is backed by ¥1 billion (US$13 million) from Japan's richest man,
Masayoshi Son. The foundation will bring together some 100 experts from around the world to analyse obstacles to
implementing renewable energy, and offer policy recommendations to the new Japanese government. ==See also==
