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.

Where else would the energy go?
“There are six types of potential energy: mechanical energy, electrical energy, chemical energy, radiant energy, nuclear energy, and thermal energy.” – [source](https://justenergy.com/blog/potential-and-kinetic-energy-explained/#:~:text=There%20are%20six%20types%20of,nuclear%20energy%2C%20and%20thermal%20energy.)
If the electrical energy in the CPU doesn’t become any of the others, it becomes heat energy. Nothing is moving against gravity, so it’s not mechanical potential energy. No chemical reactions are happening, so it’s not chemical energy. It doesn’t give off significant amounts of light (everything emits some IR, but not much here), so not much radiant energy. No nuclear reactions, so not nuclear energy. And it’s not kinetic energy bendy nothing is moving outside the CPU. All that’s left is thermal energy!
