Myth 2: Coal is Clean. Consequently, more coal would be mined, transported, processed and burned, increasing the amount of air pollution and hazardous waste generated by coal plants. The cost of construction of CCS facilities and the "energy penalty" would almost double the costs of electricity generation from coal, making it economically unviable.
