I don't think you have a very good picture of the energy costs involved. Half of the energy costs in the total worldwide collection of information systems are in wireless links at the edges of the network (mobile networks and wifi). So if you traverse two wireless links on the way to your pizza joint it is likely that you have caused the worst-case energy usage. An optical link to your nearest cloud datacenter is going to need less energy. Not to mention the now-always-on nature of the pizza place's PC, which can't be as efficient as a multi-tenant cloud system, has terrible AC/DC conversion losses, spectacularly bad HVAC inefficiency, etc.
