I mean isn’t this wrong? It may be near 100% but there’s never 100% conversion to a single kind of energy. For example, even if it’s just a tiny faction, magnetic field convert electrical energy to kinetic energy, no?
I guess we could also say that eventually that heat will escape outdoors and be radiated back into space, a tiny fraction of that will end up on the sun, and be sent back again.
No way a teacher wouldn’t know this!

100% of that tiny fraction still returns to heat.
Ah so we count following convertions. That clarifies things, thx.
