Because every month media are happy to bash on bitcoin energy consumption, but no one wants to talk about working ACs in banks during non-working hours or poor housing insulation like single glass windows or uninsulated bricks. I'm sure these cause more energy waste then Bitcoin mining.

I know Bitcoin is wasting it for nothing as there are faster and zero-mining (and zero fees) cryptocurrencies that eliminated that problem, but please someone with enough knowledge estimate energy waste from AC in US banks during non-working hours.
