I would champion repairability of the machine over any marginal additional efficiencies you can get out of it by making it more "energy-efficient". The worst one I can find is rated at 78kWh vs the best at 47kWh. I'm pretty sure making the machine and disposing of it when it breaks instead being repaired obliterates that savings immediatiely. Easy to repair designs is the only sensible way forward to reduce energy consumption during the whole life cycle of the devices.
