The value of bitcoin may have stumbled in recent months, but in Iceland it has so far only known only one direction: upward. The stunning success of cryptocurrencies around the globe has had a more unexpected repercussion on this island of 340,000: It could soon result in an energy shortage in the middle of the Atlantic Ocean.
As Iceland has become one of the world’s prime locations for energy-hungry cryptocurrency servers – something analysts describe as a 21st century gold-rush equivalent – the industry’s electricity demands have skyrocketed, too. For the first time, they now exceed Icelanders’ own private energy consumption and energy producers fear that they won’t be able to keep up with rising demands, if Iceland continues to attract new companies bidding on the success of cryptocurrencies.

And over the last three months, we have received about one call per day from foreign companies interested in setting up projects here.”
“If all these projects are realized, we won’t have enough energy for it,” Sigurbergsson was quoted as saying.
The Associated Press first reported the surge in demand.
Every cryptocurrency in the world relies on a so-called blockchain platform, which is needed to trade with digital currencies. Tracking and verifying a transaction on such a platform is like solving a puzzle because networks are often decentralized and there is no single authority in charge of monitoring payments. As a result, transaction involves an immense number of mathematical calculations, which in turn occupies vast computer server capacity – which requires a lot of electricity.
The bitcoin rush may have come as a surprise to locals in sleepy Icelandic towns that are suddenly bustling with cryptocurrency technicians, but there’s a simple explanation to scientists. “The economics of bitcoin mining mean that most miners need access …read more
