One bitcoin transaction now uses as much energy as your house in a week -- Motherboard, November 1, 2017. Bitbcoin's surge in price has sent its electricity consumption soaring.
Bitcoin mining guzzles energy -- and its carbon footprint just keeps growing -- Wired, December 6, 2017. Bitcoin is slowing the effort to achieve a rapid transition away from
fossil fuels. What’s more, this is just the beginning. Given its rapidly
growing climate footprint, bitcoin is a malignant development, and it’s
getting worse.
That's a legitimate story; a legitimate concern. Look at this,
over at the Associated Press:
New gold rush: Energy demands soar in Iceland for bitcoins.
Iceland is expected to use more energy "mining" bitcoins and other virtual currencies this year than it uses to power its homes.
With
massive amounts of electricity needed to run the computers that create
bitcoins, large virtual currency companies have established a base in
the North Atlantic island nation blessed with an abundance of renewable
energy.
The
energy demand has developed because of the soaring cost of producing
and collecting virtual currencies. Computers are used to make the
complex calculations that verify a running ledger of all the
transactions in virtual currencies around the world.
In
return, the miners claim a fraction of a coin not yet in circulation.
In the case of bitcoin, a total of 21 million can be mined, leaving
about 4.2 million left to create. As more bitcoin enter circulation,
more powerful computers are needed to keep up with the calculations —
and that means more energy.
The
serene coastal town of Keflavik on Iceland's desolate southern
peninsula has over the past months boomed as an international hub for
mining bitcoins and other virtual currencies.
