The refrigerator example isn't exactly the strongest counter argument; the fans being used to blow out the thermal energy still require continuous amounts of electricity. And actually, if anything; as far as air conditioning is concerned. Cooling areas require more energy than warming areas due to a variety of factors. There's the fact that most people use gas to heat up areas, which burning gas is more so a chain reaction and is cheaper, though not renewable unlike solar or wind powered energy.
Refrigerators don't need fans to function, they have fans so that they can cool things more quickly. That isn't the strongest counter argument against that counter argument.
Also, there are other factors if this article has something to say about that. There are scientific facts that even the human body naturally produces heat, and the more muscle the person has, the more heat they do produce. That's where the saying "Tough guys don't get cold" comes from. So in other words, it is naturally more difficult to freeze someone who's really strong and/or more durable.
This is barely a factor. A human that outputs 100x as much energy might take 1.2x as much energy to freeze. And considering that this is just due to the existence of muscles, and not directly correlated to the output of joules, it won't matter much for most fictional characters.
Anyway, Energy extraction or injection is still manipulating the energy the same way but in the opposite direction. Creation is equal to destruction for the very same reaso
Just to bold this for emphasis,
creation isn't energy extractio.
Creation requires adding energy to a system. If there's nothing there and you create something,
you used your energy to add it into the system. Destruction is also adding energy to a system. Cooling is neither of these, as it's extracting energy, it's essentially absorption, which we don't scale to AP.
Turning mass into pure energy is the same as turning pure energy back into matter... but it's still the same principle of input being equal to output.
I don't agree with this being a comparison to heating and cooling being equivalent. To turn something from energy to matter or from matter to energy only requires the correct circumstances, and doesn't require a specific amount of energy. What stays equal is the total energy in that pure energy/mass after the end of it.
This is not true for heating and cooling. They both require transferring energy into/out of a system, and at the end of it, you're left with a different amount of energy in the system. This isn't swapping things between states, it's completely changing the energy level.
To simplify:
- 1. You change the circumstances requiring little energy, and the total energy afterwards remains the same.
- 2. You add or remove large amounts of energy, and the total energy changes immensely.
These two things are disanalagous.
