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

Energy can neither be created nor destroyed so in the grand scheme of things, everything is 100% energy efficient one way or another.
