Electrical energy goes into my GPU and changes to heat energy.
Is 100% of the energy being changed to heat when mining, or is there a small portion that is still electricity? The data bits I am sending to the BTC network must still be electrical energy, right?
In theory, 100% of the energy is converted to heat but not as efficient as a heater... no matter what the electricity is used for, it will still product heat for that part....
