Are you suggesting emissions due to human consumption are negligible factors in climate change?

Otherwise, I presume emissions = energy consumed = mass * distances the mass is moved.

No I'm suggesting that consumer vehicles and residential use are relatively minor and small shifts will indeed have small outcomes.

We basically need to massively downscale or change the industrial products, supply chains and industrial power solutions in play.

Arguing about sedans vs SUVs or bus riding is rearranging deck chairs on the titanic.

Where does all the demand for energy come from? Does it not come from people wanting to live on a quarter acre lot with their own car? Which then necessitates space for parking lots and huge roads? Which then necessitates transporting goods further and further?

Where does the demand for shipping cheap plastics and electronics across oceans come from?

“Industrial” energy use is a function of consumer demand. At the end of the day, more people wanting more things (including space) and wanting to go more places is going to be the root cause, and the solution has to start there, barring a miraculous discovery of a cheap energy source without the current problems.

How much steel is used in your house and your car? How many KW does it take to run an industrial smelter?

How much more steel is used if your house is twice as big?

How much steel per sq ft of yard do you need? (I suppose your fencing needs nails...)

And do you think a smaller house will reduce that? How small of a house do you need before that demand radically drops?

> Which then necessitates transporting goods further and further?

And it's not the "last mile" (to the consumer) part that requires the energy. It's the raw materials to the refinery, the processed meterials to the fabs, the chiplets to the assembler, the boards to the injection molding plant, the molded parts to the distribution warehouse, the distribution warehouse to the seller, the seller to the reseller, then finally the reseller to the consumer.

Even if you set up camp in the Amazon warehouse, how much energy savings is that? And that is ONLY transport.

Industrial use itself, excluding transport, is huge. Building homes (and much worse for building skyscrapers). Your 250T crane wasn't built in town. Neither was the fleet of trucks to level land. Neither are the several thousand feet of fire sprinkler tubing.
