In 2007, the Chinese government answered the call by the Global Environment Facility to begin banning all inefficient light bulbs. According to a 2008 study by China’s Energy Research Institute, if China pursues a LED-heavy switchover by 2020 (which now appears likely), approximately 85 TWh of energy could be saved, roughly equivalent to the Three Gorges Dam’s annual output. This phase out is but one of the energy efficiency strategies that helps support China’s ambitious energy goals in the 11th and 12th Five-Year Plans.
