What Should we do to Protect the Environment for Future Generations? For Countries Rich in Natural Gas Build high efficiency combined-cycle plants (but plan fuel diversity) For Emerging Countries with Small Installed Grids and low Natural Gas Reserves Build small (250-500 MW) coal plants using modern day subcritical technology with low NOX burners and post-combustion emissions controls for SO2 and particulates For Emerging Countries Rich in Coal with Large Installed Grids and Mature Countries Rich in Coal Continue to clean up/retire old coal-fired operating units Build large (600-1000 MW) supercritical/ultrasupercritical coal plants with post-combustion emissions controls for NOX, SO2 and particulates Embrace IGCC as it becomes more commercially available Continue development toward CO2 capture
