I mean, while we could definitely be more efficient, you realize most of the energy we use in industry not oil related is for things like food, homes, clothes, transport, etc… Wepons are high cost, but ultimately not made at anything like the scale that most other industries operate at.
House wise, nothing can compare to heating and air conditioning in terms of energy use. Heat pumps are very efficient, but they’ll still burn though far more energy than a electric car, much less things like stoves and driers. There are limits to how well you can insulate a home without health risks, and getting close to that still requires pumping in cold air and venting warm to carry out co2. To say nothing of having to also abandon a lot of warm areas becuse they’ve gotten to hot to be safe without heat pumps.
If we are to replace fossil fuel in heating, and exterminating everyone in Canada, Mexico, and the Middle East is off the table, then we need to vastly expand our electricity production.
