Looking at glass, or cement. Do you know a heat pump that runs at up to 1600 C? So it’s just plain ohmic heating. And it’s a 24/7 process, so it needs electrochemical backup. Do you know what that does to your EROEI?
It’s not the first cab off the rank. Processes that are energy intensive may need careful consideration and I’m sure smart minds will work it out. We need to move forward and economics of energy production are shifting rapidly which will initiate change. It’s always been the case.
Careful consideration doesn’t work around thermodynamical limits very much, I’m afraid. When we move forward, we do not energy transition but rather add new atop the old: we never stopped burning classical biomass, coal or natural gas. Renewable energy is just a new thin layer on top. Depletion of mineral resources necessary for renewable infrastructure buildout and maintenance indeed does a number on the overall economics and energetics, but unfortunately in the wrong drection.
