Ken Isono has an insatiable appetite for going to different places, learning about them and connecting with local people.
It was when he traveled to over 30 countries as a backpacker in his final year of university that he became aware of the gravity of global environmental challenges and started to believe in the potential of renewable energy as a viable solution.
Three months after the 2011 Fukushima nuclear accident, Isono set up a venture with his fellow workers at a wind power firm in the hope of promoting renewable energy. Since then, he has witnessed disaster-prone Japan's gradual shift toward green energy.
