>one bitcoin transaction consumes 1,449 kWh

Thank you, I knew it was an energy hog, but had never looked at it this way.

That's enough electricity to melt 2 tons of aluminum, or about half an hour of peak production from an average size US wind turbine.

Bitcoin is not the only digital token technology. Ethereum consumes a fraction of the energy Bitcoin consumes.

Right Ethereum is really lucky to have Bitcoin around to make it look good. It (very recently) cut it's energy usage by ~99.84% yet one ETH transaction is still 50x the amount of energy as a MasterCard transaction

Thanks for clarifying. This seems to be a better picture of reality compared to your previous comment.
