Coal: A Complex Natural Resource - USGS
Coal production is forecast by the EIA to grow to approximately 1,300 million tons by 2020, of which domestic use will account for 1,279 million tons; of that amount, 1,177 million tons will be used by electric power plants. These figures indicate a rate of growth of approximately one percent per year for both coal production and power plant use.
