Yeah, don't let the bashers get you down: wasting stuff just because it's cheap is how we got here. Measuring your power use is the only way to make informed choices, and sometimes the results are surprising.
Like, I was surprised to find that my audio gear uses exactly the same power whether it's playing or not. The subwoofer alone uses twice as much power as the RPi that feeds it signal. It's maybe 0.02 USD/day (for the sub), but I've got extra smart plugs from a multi-pack, and it's easy enough to put together an automation to power them all down if they've been idle a while.
Not really, at least if we're talking about electricity use.
We got here by expanding our standard of living. Most residential electricity use is heating, cooling, and other major appliances, and we're not going to make up for that by cutting a few watts here and there.
Don't get me wrong, I'm absolutely in favor of small wins, but it's important to not miss the forest for the trees. For example, don't throw out good hardware just to save a few watts. If your goal is to help with climate change, there are much better ways to spend your time than cutting a few watts here and there.
