  Well ultimately it all becomes heat. Maybe a tiny amount escapes a window or something. So we could say 99%.

  But heat pumps still reign supreme, at least until it gets super cold.

    In the end we are all infinitely falling into the pit of entropy

  Light is just heat energy

    Well that’s just objectively wrong. Light is EM radiation, where heat is movement of atoms and molecules. Via incandescence objects can radiate away their heat (following black body radiation), however they are not the same thing.

      What happens when photons emittes from the heater hit items in the room? That energy is imparted into the object, heating it up.

        If we’re going to be pedantic, let’s do it correctly.

        Even with the blinds shut, a space heater will emit a surprisingly large amount of radio waves (mine actually disrupts USB devices with a small EMP when it turns on, and anyone with an RTL-SDR can tell you those 50 Hz harmonics are rough). Some of those radio waves will penetrate the walls/blinds and a tiny fraction might escape the atmosphere and head off into space. From there some will find their way to interstellar space and potentially drift “forever” (well, until the heat death of the universe or whichever theory you subscribe to; I think at that point saying “the photon never got converted into heat energy” is a good enough approximation).

        So then you state: The light will become heat energy.

        Sure, but like the other commenter said, everything turns into heat eventually

        The heat isn’t transmitted via photons, it’s transmitted via convection. The air acts as a medium to transmit the heat energy outward. The heating element itself emits photons because it gets hot enough where the atoms within vibrate at a frequency which reaches the visible spectrum of light. That’s why cooler elements glow red (lower frequency) and hotter elements glow blue (higher frequency). Most of the heat energy is not contained in the photons, you need an output on the level of the sun to achieve that. With regards to the sun, all of the energy is carried by radiation anyway, because convective currents can’t travel in the vacuum of space.

      heat is movement of atoms and molecules.

      Moving atoms don’t physically touch each other. They transfer their momentum with photons.

        Wtf, is that true? Aren’t photons weightless? It’s all black magic.
