how does a cpu convert virtually 100% of energy to heat when it uses energy to do calculations?

I’m confused. I did some research online, and learned that cpu’s can essentially double has a hotplate, because 99-100% of electricity consumed is turned into heat. how? doesn’t the cpu use energy to make calcuations and render things? I’m real confused.

When you use wood to create heat or light, you use it up and it becomes ash.

This is true of all fuel. The ash may be solid, or smoke, or a gas like CO2, but to use the fuel, you have to turn it into ash.

Heat, specifically heat that is dissipated into the world, is the ash of energy. When you use energy to do anything, you generate heat, and that heat is always spread out into the world. When you have more heat in one place than another, you can use this heat to make energy, but doing so spreads it out and thus uses it up.

When you use energy to do work, the result always is heat, and if you start with heat you always make more and the final heat is always more dissipated than what you started with.

Or, dissipated heat is ash.
