Wasted energy isn't just heat, it also includes chemical energy (chemical bonds), kinetic energy (noise and vibration), activation energy (chemical reactions), and light.

So a lamp that heats up the room but also makes noise is not using its energy 100% efficiently. Because the noise is not wanted.
