Closing the "green gap": energy savings from the math of the landscape function

Electricity use went up in your case, but switching from oil heat and an internal combustion car to heat pumps and an EV should mean that your overall energy use has gone down fairly significantly (down to 1/3 or 1/4 of the energy used on heating and driving).

So that's not quite the Jevons paradox unless you're going to drive three times the distance or expand to heating four times as much space in your house.

If food gets 10x cheaper I'm sure I'll eat 10x as many calories! /s

Food demand is relatively inelastic.

Overall energy efficiency has improved by about 35% in my napkin math, but I find whenever I improve efficiency, my electricity usage increases. This applies to both electric sources of energy and non-electric sources of energy as something new always seems to follow the efficiency gain. The reduction in overall energy usage is a side effect of efficiency difference of the heat pump (although on a dollar basis, costs remain about the same) being huge and is an abnormally.
