updated daily, now shows the network consuming 67TWh annually, just under that upper bound.7GW shown in his new study. Every miner individually confirms whether transactions adhere to these rules, eliminating the need to trust other miners. A detailed examination of a real-world Bitcoin mine shows why such an approach will certainly lead to underestimating the networks energy consumption, because it disregards relevant factors like machine-reliability, climate and cooling costs. The machines performing the work are consuming huge amounts of energy while doing. Although it has been around since 2009, the digital currency, or crypto-currency, has been dominating headlines across the globe recently thanks to its soaring value. In equilibrium, that should mean that energy use falls by half as well. So far, it seems that only miners are currently shifting toward cleaner parts of the world. While working on the blockchain these miners arent required to trust each other. Burning huge amounts of electricity isnt incidental to bitcoin: instead, its embedded into the innermost core of the currency, as the operation known as mining.

Morgan Stanley accurately captured the main problems in this approach in their report Bitcoin asic production substantiates electricity use (January 3, 2018 explaining that the hash-rate methodology uses a fairly optimistic set of efficiency assumptions and may not allow enough for electricity consumption by cooling. Bitcoins energy consumption has become a recent talking point in the debate. With a new block being created every 10 minutes, that works out to around 15 million per day in mining revenues. Energy consumption model and key assumptions Even though the total network hashrate can easily be calculated, it is impossible to tell what this means in terms of energy consumption as there is no central register with all active machines (and their exact power consumption). Of course, the Bitcoin Energy Consumption Index is also very much a prediction model for future Bitcoin energy consumption (unlike hashrate-based estimates that have no predictive properties).
One analyst, Marc Bevand, argues this method is wrong because it does not take into account newer and more energy-efficient technology employed by miners, adding it makes "the wrong assumption that a fixed '60' of mining revenues are spent on electricity". So Reality Check wants to know: how did they work it out, and is it true? If you assume that the entire network is using the most efficient known mining hardwarethe Antminer S9 from Bitmainthat yields de Vries's lower bound energy consumption.6GW. Although there has been extensive discussion in the media of bitcoins energy consumption, Im not aware of any studies that actually calculate the comparative carbon footprint of the bitcoin process. The zero-sum computational race that drives bitcoin's prodigious energy consumption has very little to do with the number of transactions per block.
