Solar is EU’s biggest power source for the first time ever | Ember

This is just Germany, but here it holds true: https://www.energy-charts.info/charts/energy/chart.htm?l=en&c=DE&year=-1&stacking=stacked_percent&interval=month&legendItems=0x7vru&month=-1

Spain and Italy have lots of Solar too, idk about the more northern countries, but it seems plausible to me. It doesnt say "majority" and achieving "biggest" isnt all that hard because the total is just split up between so many types of sources.
