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.

Energy can’t be “used up” entirely it can only be converted into a different, usually less useful form. In a CPU electrical energy is converted into waste heat.
