&gt; How would bitcoin&#x27;s power consumption stack up if it were tasked with servicing tens of millions of transactions per second?<p>There is no way to do this calculation. At the moment Bitcoin mining uses, let&#x27;s say 150MW and can do around 4 transactions per second. If you gave the network a 1000 times more hashing power, you&#x27;d be using 150GW, and could handle... around 4 transactions per second.
