It’s probably correct to say what is
visible in the exhaust is water droplets (condensing water vapor) since greenhouse gases are invisible over the temperature ranges around power plants. Using this to argue the exhaust is 100% clean is flawed and easily verified as incorrect.
EPA: Facility Level ComparisonsThe first three quarters of 2021 show significant changes compared to the first three quarters 2020 data:
10 percent increase for NOX
30 percent increase for SO2
10 percent increase for CO2
19 percent increase for Hg
The increases in emissions are due primarily to changes in the mix of fossil fuel-fired electricity generation. The first three quarters of 2021 showed a total fossil generation increase of 5 percent compared to the first three quarters of 2020. There was a 23 percent increase in coal generation and a 6 percent decrease in natural gas generation, which resulted in significant emissions increases from the same time period last year.
