Bitcoin's annualized footprint in electricity consumption reached an all-time high in early 2022, then believed to be higher than the power consumption of Finland. This is according to a source that tries to estimate the energy consumption of Bitcoin (BTC). It does by assuming that miner's costs and income are the same thing: The higher the miner's income, the more powerful machinery it can support. As of May 19, 2025, Bitcoin's energy consumption fell in between the consumption of Australia or the Netherlands. Note, however, there is no central authority where cryptominers report their figures to. Exponential growth As Bitcoin has a maximum supply, the closer the cryptocurrency gets to its limit of 21 million coins, the more effort it takes to mine. Not every cryptocurrency has a maximum supply. Bitcoin, however, stands out as more than 90 percent of all its coins have already been created. This exponential growth cycle indirectly impacts the overall size of the blockchain as well, as it currently grows less fast than it did several years ago. Which countries mine Bitcoin the most? According to the latest available estimates, the United States had a higher Bitcoin mining hashrate than China. This research - using IP addresses from hashers accessing certain Bitcoin mining pools, a method the source admits can lead to issues - was last held in 2022, however. It is generally assumed that the different electricity prices worldwide may impact the decision on where to mine for Bitcoin.
