While the Nordic island nation has become a hotbed for Bitcoin (available on Coinbase) mining in recent months, a serious problem has emerged in Iceland: there now may be energy shortages for powering its households.

The process of mining Bitcoin (available on Coinbase) is an energy-intensive endeavor. According to reports; a single transaction uses the same amount of energy as the average U.S. household in a week.

With an influx of miners looking to take advantage of Iceland’s electricity infrastructure, climate, and lenient regulations, the amount of energy consumed in these mining operations is unsurprisingly unprecedented for a nation that only houses 340,000 people.

In fact, the energy consumed in mining has already surpassed Icelanders’ own private consumption, and a nationwide energy shortage is imminent as producers are struggling to keep up with the rising demand.
