If a machine is never 100% efficient transforming energy into work because part of the energy is converted into heat, does it mean an electric heater is 100% efficient? [@showerthoughts@lemmy.world](h (social.graves.cl)

If a light bulb gets dinged for leaking light outside of the house, then a computer, a computational and informational device, should also get dinged for any light not absorbed by eyeballs and any errant processes/calculations running without discrete need

The light leaving the house decreases heating efficiency because the energy quite literally went out the window. If you run needless calculations or look away from the monitor, that energy still ends up heating your house
