China only has coal reserves left for about 12 days, and in some regions only about a week's supply is left, Australia's News Network reports. The demand for coal—the most important energy source in the country—has skyrocketed, with huge numbers of new power plants being built in the past decade.
China relies on coal for about 70% of its energy. The China Electricity Commission says the reasons for the present shortage are "multi-dimensional." Since March, reserves have fallen 12%, to 46.7 million tons, the Commission reports.
