A simple "back of the envelope" power use calculation of the possible power use of the bitcoin network, using the total hash rate from https://www.coinwarz.com/mining/bitcoin/hashrate-chart ( 151.55 EH/s ) and assuming all Antminer S19 (110 TH/s for 3250 watts)

gives me a total power use of 0.00445 TWH which is very different to the 121 TWH on the cbeci site.. even given the efficiency range of mining gear (like if spread of included hw included stuff 10 x less efficient), cooling systems etc, what am I missing? I dont do these power calculations often so have a left a parameter out?
