From @2x4caster.bsky.social on LI. The point about resins and waxes going into wood paneling products is a big one for me. There's so much downstream from oil and nat gas that directly help make other things. It's an energy input AND responsible for a litany of intermediate goods.

Things not considered, but that have small costs. Most not widely used: Premium homes may have struct stl, pipe columns, metal roof, truss plates, all other fasteners, fixtures, appliances (more than a small cost).

Haven't done aluminum, but I suspect it's a lot less than steel. Structural steel is 10% of bldg total cost. Most aluminum I think is used in window frames, both exterior and interior office glazing. That's a lot less than 10% of total bldg cost. Now, if a bldg has alum exterior wall panels, then...

Yes. Steel adds almost 0 cost to a SF residential bldg. Same with alum.
