Your calculation is invalid too. Mining energy is not just used to process a transaction. Miners really do it to generate more BTC. It is the energy of the whole network. You're not including all related activities like the energy used in Apples banking and advertising, flying their employees around etc Less BTC is generated over time, eventually none at all. The energy usage has no relation to actually performing a transaction. All of the 'BTC energy usage' calculations that talk about future climate change estimations and come up with 'per transaction' values are completely invalid.
