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.

These aren’t really ELI5 answers.

Imagine cars on one of those super highways in China with 20 lanes. Now imagine all the cars are in a traffic jam and can go 0-60 in 1 second.

Now imagine, the road is split into 1 mile segments, alternating segments full of cars and empty segments.

Let’s say once the segment in front of the cars is empty, all the cars in that group are allowed to go forward/ accelerate at full speed until they reach the next segment of cars clearing out, and regroup themselves.

That’s going to be a lot of burnt rubber (tires producing a ton of heat to go as fast as possible from limited movement), when they have to slow down that’s a ton of heat from all the breaks so the cars so they don’t hit the ones infront. Plus the engines.

Now scale that down to an about the width of your hair.

Thats a lot of heat!
