The economic impact of water shortage on the efficiency of thermo-electric generation, as noted above, deserves additional analysis and quantification. Temperature-related efficiency losses will not only become greater in response to reductions in available cooling water volume, but will be further compounded by a gradually warming climate. While the impacts on the electrical output of individual plants may be small, the cumulative impacts could be considerable. Better recognition and quantification of the thermal-related risks to generating efficiencies could also offset a significant portion of the existing life-cycle cost differential between fossil-fuel based generation and renewable alternatives.
