<P> Coal remains the foundation of the Chinese energy system , covering close to 70 percent of the country 's primary energy needs and representing 80 percent of the fuel used in electricity generation . Coal has grown rapidly in importance in recent years along with the rising demand for electricity . In 2011 , according to the IEA , Chinese coal production was equivalent to 3,576 Mt * 0.522 toe / Mt * 11.630 TWh / toe = 21,709 TWh . Assuming the same caloric value for the imported coal , the net coal energy available would be 22,784 TWh . Equally calculated available coal was 17,000 TWh in 2008 and 22,800 TWh in 2011 , with increase of 5,800 TWh in three years . Total renewable energy in China was 3,027 TWh in 2008 and 2,761 TWh in 2005 , with increase of 266 TWh in three years . Same period from 2005 to 2008 annual coal use increased 3,341 TWh . </P>
