“Organisations which continue to operate older PCs and notebooks as software thin clients can make a valuable contribution to protecting the climate and also make savings over the full life cycle of their devices
the production of the devices was responsible for a high proportion of the CO2e emissions. Conversely this means that simply continuing to use older devices as logical thin clients makes a significant contribution to protecting the climate since it prevents and/or defers the production of new devices.”
See: software thin clients are both climate and wallet-friendlyYes, besides offering the performance of new server hardware to users of older PCs, thin clients save a ton of money as well as CO2 emissions. There’s no downside for thin clients except full-screen video. Extending the life of older PCs by years using them as thin clients does throw away the benefits of Moore’s Law in using less energy with lower CPU and RAM energy consumption in use but trades that for the immense energy cost of producing a new PC. The old days of replacing PCs every ~3 years was obscenely expensive. Decent PCs can be used for a decade or more as thin clients. That’s the right thing to do for most of us hunting and pecking away.
I recommend using Debian GNU/Linux on both the server and the thin clients. Thus you get away from That Other OS and it’s licensing burden, malware, slowing down, complexity, etc.
