    Nationally, waste coal has an average of 60% of the BTU value (British Thermal Units, a unit of energy) of normal coals. It can take up to twice as much waste coal to produce the same amount of electricity. This means that -- in most places -- waste coal burners can only be economically built where huge volumes of waste coal exist.
