My gas furnace supplies a baseline of heat, and my basement gets topped up with electric heat. What are the mechanics of energy usage for me?

I feel like all energy is converted to heat in my laptop. That would mean free computing power?

Am I missing something? Can energy be converted to a form I am overlooking with computational work?

All heat from your electronics (CPUs&GPUs) are waste heat, you could replace your electric heater with a computer to get "free computing power".
