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.

For the little transistors, “being a 1 or 0” doesn’t cost energy, “becoming a 1 or 0 after having been a 0 or 1” does. Think of it this way: the 1 and 0 state are like a ball lying on either side of a hill. It is perfectly content to lie around there. To make 1 from a 0, you need to push the ball up the hill, and when it rolls down the other side, it needs to stop and stay in its new place. Its energy is now the same as before. All the energy you put in must have become heat through friction with the ground to stop the ball when it rolled down the hill. This is not exactly the same as a 1 and a 0 for a CPU, but it shows that you can change things around, and all the energy you put in just becomes heat.
