Indeed. We’ve become denizens of a sprawling complex World civilization dependent on the ultimate power of the sun. Solar and wind technology is insufficient to meet these needs. So are our so called leaders who if a transition was possible wouldn’t be capable of managing one. We need brain power and the ability to manage communication/diplomacy. The Vikings didn’t drive SUV’s or Jet planes, farmed Greenland and had some pretty hostile diplomacy skills. Watch The Northmen on this subject, lol.
