Brookings senior fellow Charles Frank has calculated that replacing coal with modern combined-cycle gas turbines cuts 2.6 times more emissions than using wind does, and cuts four times as many emissions as solar.  If anything, these figures are likely to be too generous to renewables. Frank uses conservative assumptions about the energy consumed for balancing and cycling (starting up or shutting down gas-fired plants). Based on recent research, Edinburgh University’s Professor Gordon Hughes found that balancing costs are nearly ten times higher than Frank’s assumptions and that cycling reduces the amount of CO2 up to 50 percent more than wind turbines do (relative to the classic grid-average method of calculation used by most official bodies such as the International Energy
