From the late David JC MacKay's book "sustainable energy: without the hot air" [1] we have the following estimates for per-capita energy consumption in the UK:
the "stuff" category is the energy required to manufacture stuff, including gadgets, houses, cars, roads, washing machines, newspapers, drink containers, computers, etc. note that the energy cost of house construction is estimated at 1 kWh/d per person, while the cost of a new car with a 15 year lifespan is 14 kWh/d, the ignoring energy to run it.
The combined energy cost of stuff and stuff transports is the biggest impact on the list.
although arguably the car is the worst offender if you account for the energy cost of the stuff lifecycle and the energy costs to oeprate it. The estimated energy cost of manufacturing a car with a 15 year lifespan accounts for 14kWh/day of the 48+ kWh/day "stuff" estimate, so if the use of a car was replaced with a magical transport device that required no energy to manufacture or run or dispose of, that would eliminate 14kWh/day from "stuff" and also eliminate the 40 kWh/day car operational energy cost too.
all units are kWh/d
