This same article gets brought up continually by people who either want to discourage bitcoin use or just don&#x27;t understand how it works.  Disregarding for a moment that their calculations are ridiculous and that the article is over a year old when there was less volume, bitcoin transactions and the energy used for mining are uncorrelated.<p>The electricity used is the level of security, the number of transactions supported are completely separate and could easily be orders of magnitude larger if the block size gets expanded (which is a whole other issue, but unique to bitcoin at this moment).
