The trend of warning of the negative environmental consequences of the use of cryptocurrencies, especially Bitcoin, entered a new phase by rejecting Tesla's acceptance of these currencies. However, supporters of the extraction of virtual currency from Scandinavian countries point to this as a successful example.
Nordic countries including Iceland, Norway, Finland and Sweden have a long and successful history of clean energy production. A few years ago, for example, studies began on plans to move the surplus of electricity generated in Iceland to the UK. The use of numerous wind turbines and offshore flows, on the one hand, and the low population of these countries for the consumption of huge energy produced, since about two decades ago, opened the feet of computer companies, especially the giants of data processing and blockchain, and subsequently virtual currency miners to this region.
