Vampire power is a thing, but not really that huge since regulations have launched the 1W initiative. The vampire power consumed by the average house in the US is less than a thousandth of the entire energy consumption. Less than a dollar per year. Of course, over a couple million homes we are talking about a few million dollars, that’s not nothing. But also, it’s less than a 0.001% of the entire grid residential electrical consumption. To cut power emissions and usage, that’s almost a non-issue at best, a distraction at worse.
