Clean generation growth from in last 5 years
Hydro 291,724 - 259,367 = 32,357 GWh
Wind 274,952 - 181,655 = 93,297 GWh
Solar (LS) - 66,604 - 17,691 = 48,913 GWh
Solar (SS) - 29,543 - 11,233 = 18,310 GWh
Total growth = 192,877 GWh

------------------------------------

Also in the last 5 years, generation from natural gas grew by 341,404 GWh, somewhat larger than the growth of hydro, wind and solar recorded above.
1,468,013 - 1,126,609 = 341,404

At an average heat rate of 7812 BTU/kwh (last year recorded), and a natural gas emission factor of 53 kgCO2/million BTU, that natural gas generation produces...
(341,404 GWh) x (1000 MWh/GWh) x (1000 kwh/MWh) x (7812 BTU/kwh) x (53 kg/1E6 BTU) x (1 Tonne/1000 kg) = 141,353,546 tonnes of CO2 per year

141 million tonnes of CO2 per year from the growth in nat gas.

You could argue that the decrease in coal was larger than the increase in natural gas, which is true. However, the growth of natural gas generation is still larger than the growth in renewables, by quite a margin.

Bottom line: Intermittent, low capacity factor and non-dispatchable renewables (solar, wind) plus natural gas will always produce more CO2 than nuclear. This is why Germany's Energiewende has been such a failure. France (and Sweden) (and Quebec, Canada) with their nuclear power fleets produce much cleaner electricity than Germany's much praised renewables with needed back-up fossil fuels.

Germany: 510 grams of CO2 per kwh
France: 51 grams of CO2 per kwh
