A lot of jumping to conclusions with very little evidence in this thread.

Nah no way does the average ewaste tier laptop use less power than a raspberry pi for any given task. The power consumption floor for a laptop may be lower than the rpi ceiling but that’s not a fair comparison

Not so sure about the last part. It takes ehhh about 3kg of c02 to produce 1 Watt for a year. Carbon footprint to build a laptop is about 200kg or so, but you’re not offsetting one of those you’re offsetting the raspberry PI you WOULD have bought which is just a small fraction of that. After a year or 2 you’ve almost certainly burned through your c02 savings if it’s on all the time.

Back when I lived in a (quite nice) apartment building I was constantly surprised at the things people threw out. Perfectly good furniture but also stuff like perfectly functional printers, artwork, computer cases…
