Denmark didn't "transition" its grid—it replaced it.

 From Chris Meder, EVCurveFuturist

Denmark didn’t “transition” its grid—it replaced it. ~15% → 92% renewable electricity in 25 years. Wind did the heavy lifting. Solar is scaling. Interconnection balanced. Flexibility solved variability. Wind built it. Solar is scaling. Fossil lost it. This IS system replacement. ⚡#Bettrification

If little Denmark can we do it, we all can. There are no longer any technological hurdles to overcome. Technical hurdles, yes. There are no longer any economic hurdles either. The only factor standing in the way is vested interests.
