It was kind of a statistical tie the last time I looked at this (wind was possibly slightly in the lead out of the three in terms of CO2 per KWh) but the wind and solar numbers seemed to be trending downwards over time.
2014 data from an IPCC meta-analysis here roughly supports this [1]. 800 gCO2-eq/kWh for coal, 490 for gas, 48 for solar, 12 for nuclear, 11 for wind.
To be clear, any non-carbon energy source can decarbonize almost to zero assuming all the lifecycle activities are converted to the non-carbon energy as well. One exception might be hydro with it's potential biogenic methane emissions.
Germany uses ~30% Coal in its energy mix, France less than 2%.
Your argument is misleading at best, and targeted misinformation at worst.
Since you've repeated the same argument at least 5 times by now, even though others have informed you about the wrong conclusion, I must assume it is meant to misinform.
