As the price of Bitcoin has shot up to its current value of around $100,000 (£75,000), ever-increasing amounts of computing power have been needed to win crypto rewards, shutting out smaller miners in favour of large collectives and companies.As well as the hum, mining's energy use has environmental impacts. A Harvard study published in March in the peer-reviewed science journal Nature Communications found that Bitcoin mining exposes millions of Americans to harmful air pollution each year - and that 34 Bitcoin mines consumed a third more electricity than the city of LA. (There was some pushback from the crypto industry to the study, which was called The environmental burden of the United States' Bitcoin mining boom.)
According to the Cambridge Bitcoin Electricity Consumption Index, mining globally uses approximately 0.7% of global electricity consumption.That has a knock-on effect on local energy prices, which is also provoking a backlash in some areas.In 2017, Bitcoin miners flooded into Plattsburgh, New York – a city of about 20,000 people a couple of hours to the north of Dresden – because of cheap hydroelectricity rates. "We were getting Bitcoin applications from operators all around the world," says the city's mayor at the time, Colin Read.
Yet they used so much power that electricity rates shot up. Within a year, some residents were paying up to 40% more during winter months, Read says.The following year, he and other local lawmakers passed rules against buildings blasting out hot air.
"Fortunately we put a stop to it," he says, noting that all but one Bitcoin mining operation left the city.
Resistance to Bitcoin mines extends to places with the biggest Trump support.After the attack, he left towards Dublin Street.
Police Scotland said door-to-door inquiries were continuing.Local residents and businesses have been urged to check storage areas or lock ups and to report any suspicious items or behaviours.
It's an interesting question – perhaps a little niche. But it's certainly not a question you'd expect to find a senior member of Kemi Badenoch's team openly pondering.The shadow cabinet minister went on to stress that they were more optimistic: that the resilience of what is often called the world's most successful political party should never be underestimated.
