Bitcoin mining around the world consumes 29.05TWh (terawatt hours) of electricity annually as of 20 November, according to a website that claims to provide in-depth analysis, opinions and discussions with regard to bitcoin and other cryptocurrencies.

Digiconomist listed the energy consumption of many countries to contrast this against; for example, Australia's annual consumption is 224 TWh, which makes the bitcoin energy use 12.97% of the country's consumption.

Another website, Power Compare, claimed that given the rate at which the growth of the cryptocurrency is occurring, bitcoin mining would consume all the world’s electricity by February 2020 (21,776 TWh).

The energy that goes on bitcoin mining is more than 159 countries, according to statistics compiled by Power Compare, a website that compares UK energy companies. It has a list of 219 countries and their rank as far as energy consumption goes, indicating how the consumption ranks against the energy consumed by bitcoing mining glabally.

If all bitcoin miners were in a single country, they would rank 61st in power consumption, Power Compare claimed.
