Energy chief also conservationist, poet

BEIJING - For China's retiring energy chief Zhang Guobao, conservation is not just a goal, it is a way of life.

"Good habits and a simple lifestyle make you live an energy-saving life," says Zhang, head of the National Energy Administration. "That's my creed."

He doesn't drink or smoke, turns off heating and cooling systems in his office and instead opens windows when necessary, and he often fights off hunger with instant noodles when burning the midnight oil.
