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.
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.

France: 50 million tons of CO2 per year in the energy sector
Germany: 50% renewables
France: 70% nuclear
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.
