Half of German homes use gas heat. Replacing half the furnaces in Germany will take a loooong time. My point isn't efficiency, but the size of the installed plant. I fully expect new infrastructure will use more electricity. But we have accumulated trillions of dollars of infrastructure using natural gas over more than a century. There is absolutely no way we are going to replace it all in 10 years.
