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 is a conserved quantity, it is not created or lost, only transformed. Given an electrical appliance, electricity is consumed, what types of transformed energy can come out? Heat of course. Light, mechanical movements, objects can be charged, magnet fields can be induced. Calculations are not a form of energy, those don’t count. So heat is really all that electricity becomes in a cpu. And ultimately all other forms of energy become heat too. For example a fan moves air so you would think mechanical motion is somehow different, but it isn’t, sooner or later that motion of air stops and all its kinetic energy has been transformed to heat.
