UNITED NATIONS (AFP) - UN chief Ban Ki-moon on Friday touted his commitment to promoting alternative energy sources by commuting to work aboard a fully solar-powered taxi.

"I hope that this Solartaxi, one of the alternate sources of energy, can give some good messages to the people around the world that we need to be creative, we need to be practical," he told reporters as he arrived at UN headquarters.
