Michael Saylor published a long article on his personal website, sharing some views on Bitcoin mining and the environment.
About $4-5 billion in electricity is used to power and secure the $420 billion Bitcoinnetwork today, with the output valued at 100 times the cost of energy input, he said.
This makes Bitcoin far less energy intensive than Google, Netflix or Facebook, and 1-2 orders of magnitude less energy intensive than traditional 20th century industries such as aviation, logistics, retail, hospitality and agriculture.
He also mentioned that 99.92% of the world’s carbon emissions are due to industrial energy uses other than Bitcoin mining. Bitcoin mining is neither a problem nor a solution to the challenge of reducing carbon emissions.
