Bitcoin energy usage17 Apr 2021 17:57
From a Cambridge university study in Feb 2021
The University of Cambridge's online tool estimates Bitcoin's annual electricity consumption is more than The Netherlands, United Arab Emirates and Argentina
Bitcoin uses more electricity annually than the whole of Argentina, analysis by Cambridge University suggests.
"Mining" for the cryptocurrency is power-hungry, involving heavy computer calculations to verify transactions.
Cambridge researchers say it consumes around 121.36 terawatt-hours (TWh) a year - and is unlikely to fall unless the value of the currency slumps.
Critics say electric-car firm Tesla's decision to invest heavily in Bitcoin undermines its environmental image.
The currency's value hit a record $48,000 (£34,820) this week. following Tesla's announcement that it had bought about $1.5bn bitcoin and planned to accept it as payment in future.
But the rising price offers even more incentive to Bitcoin miners to run more and more machines.
