:::: However ... If you'd take a possible (high) average of the price of a kilowatt-hour (say, in the USA) of '''15¢''', which is '''1/4¢''' per kilowatt-minute (I pay less than a dime/kilowatt-hour). Most modern PC's today have a power supply of 250 watts (or thereabouts, some home-built PCs have larger ones), but that usage is that usually only that high when starting up the electric motors for the disk drives and whatnot. Once running, most PCs use around 85 watts up to around 250 watts, excluding the monitor. So, at 250 watts for a powerful multi-core PC, and for running it for a couple of minutes, that comes to '''1/2¢'''. This is all on-the-back-of-a-envelope type calculation. Let's double that to include the monitor's power consumption and other external devices. Now, if you double that, and double it again, and then double it once again, that's still less than a nickle. If you send me a SASE, I'll send you a check. <big><big><big> 🙂 </big></big></big> -- [[User:Gerard Schildberger|Gerard Schildberger]] ([[User talk:Gerard Schildberger|talk]]) 01:57, 16 August 2019 (UTC)
