" Despite the growth of nuclear power and renewables, 85 percent of China’s energy today comes from fossil fuels. The structure of China’s energy economy differs from North America’s and Europe’s; it is heavily reliant on coal—almost 60 percent of its total energy, compared to just 11 percent in the United States. Oil is the leading source of energy today in the United States—37 percent. In China, it is half that—20 percent. Natural gas is just 6 percent of total demand, though growing fast, compared to 32 percent in the United States. "
