Changing for clear skies

Coal-fired power plants deal with tough transition to cleaner energy, but environmental benefits are obvious, as Zheng Jinran reports.

Liu Jinming had a tough time handling the high-tech equipment and coping with the complex information on the computer screens in front of him.

Liu, 50, has been working at the coal-fired heating plant in Beijing for 27 years. After facing the basic buttons and instrument panels of the plant's former operations room in the past few decades, he found himself having to study and re-train with younger colleagues to get up to speed with the latest technology.
