I have a number of Energy Star appliances.
They ALL suck.
If I see that designation on something anymore, it’s not a selling point.
A better rating would be longevity and availability of parts. We used to make things that lasted for decades and when they broke, you could get replacement parts. Now it’s all short lived china junk that you can’t fix. Everything’s disposable but no one says anything about how GREEN that isn’t. By the time you buy something, china factories are belching smoke and fumes to make it’s replacement.
