Your numbers are a bit off (2018: 155TWh solar+wind; 65TWh biomass+hydro; 2006: 158TWh nuclear as of [0]), but I'd agree with your conclusion. The biggest disappointment in those graphs is the near constant use of lignite, but politicians seem still very resistant giving up the jobs of that industry.
