The refrigerator I have today is larger, cooler, and uses less energy then the one I'd buy 30 years ago.
My phone uses less power then the one I had 5 years ago, as does my PC.
In fact every industrial manufacturing process today is using less energy then it was in the past.
- mitthrowaway2 3y agoAnd yet, the industrial manufacturing sector uses more! As does the computing sector. This is because energy consumption reduction due to efficiency improvements goes -- to be very generous -- as 1/t, and exponential growth goes as e^t, and e^t/t is still exponential for large t.
