I do too. For many use cases it's awesome to use an ESP32, Raspberry Pi or Arduino when I want to stash some little widget that can sip a small battery over the next week. It's equally awesome that in many scenarios you can be net positive in your consumption with a super simple solar panel that provides a few watts here and there into a battery.
But at home things are different. While I want to use as little power as possible, the realistic plan for being sustainable at home is to use solar with batteries. That's a plan I actually think can matter and that I am able to participate in for relatively low cost ($10k)
Messing around with a system to save a few watts for me in this context isn't very valuable.
It depends how hard it is. I installed OpenMediaVault on my Pi and it's worked great ever since. I don't think any other option would have resulted in less work for me.
As far as solar goes, where I live it's not worth getting, so I can't comment there. Raspberry Pi costs $5 a year to run. A 60 Watt computer costs $79 a year to run. I agree that if it's very difficult to setup a Pi it might be worth the extra cost for the computer, but the energy savings are pretty incredible.
