Where's it say they're more than twice as good? This isn't comparing new homes to old homes, but the overall homes over time. Obviously heat pumps, furnaces, etc are more efficient today than in 1970. If you updated an older home with efficient windows, doors, heat pump, and attic insulation, then I doubt there would be much difference.
