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

Question

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.

Making those calculations, makes heat. It’s not using energy to move physical gears, or producing light; the only form energy is being changed into is heat through electrical resistance.
