> This won't meaningfully increase air quality or reduce emissions. And using this argument inversely, those 100 watts also cannot meaningfully help others, which is what the OP wants to do. So if you have two options - meaninglessly donate 100 watts or meaninglessly save 100 watts, what’s better? If someone were in need of significant amounts processing power (which is what the OP is hinting at), obtaining it from idle consumer PCs is an incredibly inefficient method of using that power. Think on the lines of CPU mining - a totally useless waste of energy. Whatever this hypothetical person is trying to do, it would be much more efficiently achieved via specialised hardware, and the OP would be better off supporting that than donating their processing power.
