The how many households shouldn’t matter, if all companies ignored some of their products it will contribute to a bigger problem, energy efficiency should be a goal of all products. It also suggests the whole range will likely be increasing the requirements of each tier.
I can see home computing may not currently be top of the list of products governments look at but I feel it’s going to happen. I expect home mining will push it up the list.
As for cars they were producing high bhp but very inefficient engines a long time before we as society became aware of the problems with the amount of power we use. They have been on a different journey of getting more efficiency in recent years which governments have implemented taxes and regulation to push designs in this direction. In the UK it is getting harder and harder to find ‘fun’ cars where efficiency is not a primary design feature. It seems wrong at this time for a company to increase the power requirements of its next generation products, it goes against what should be happening.
