I don’t want more energy efficient things. I want more clean energy so that the things I use can work better by using as much energy as they need instead of cutting corners for efficiency.
That is a fair point, although I wonder how long this will hold true considering the ever increasing prevalence of heatpumps, sun-boilers, and other such equipment.
Stuff you should know did an episode on dishwashers and I believe if you washed your dishes for a minute, you've already used more water than a dishwasher. It was pretty mindblowing. They did, though, go through some studies that made it seem that dishwashers were too sterile and getting a little leftover or germ from your handwashed plates was better for your immune system.
That is precisely why you should let your $0/hr spawn pick up this menial task rather than doing it yourself - assuming your time is worth more than theirs, obviously :)
If your spawn is only worth $0/hr., they won’t have the capacity to handle it. If they are worth anything more, they would be more productive elsewhere. The income they produce for you will more than pay any dishwasher costs.
That's the current tradeoff in dishwashers (and washing machines), more energy efficiency means lower temperature, and then the detergents take longer to work. This is why we have 3:30 eco programs.
