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.

Calculations and information are just arrangements of electrons. Your CPU is constantly moving electrons around and checking where they are. Wires have resistance, transistors and capacitors leak. Eventually (pretty quickly) it all becomes resistive heat and you have to put more energy in to keep it going. A lot of research goes into trying to get more calculations for less heat, especially in battery powered devices like phones.
All energy becomes heat eventually. It’s basic thermodynamics. It’s just a question of how, and whether the energy can do something useful in the process. A car also converts all of its fuel energy into heat, most of it in the engine block that is dissipated in the radiator, some in the tires, and the kinetic energy eventually becomes heat in the brakes.
