One transaction can use as much energy as an entire household does in a week.
No one may be using Bitcoin but we’re all paying for them.
Bitcoin analyst Alex de Vries – otherwise known as the Digiconomist – reports that the coin’s surge caused its estimated annual energy consumption to increase from 25 terawatt hours in early November to 30 TWh last week—a figure wrote Vox’s Umair Irfan ‘on par with the energy use of the entire country of Morocco – more than 19 European countries and roughly 0.7 percent of total energy demand in the United States – equal to 2.8 million U.S. households.”
(As of Monday the figure had reached nearly 32 KWh.)
That energy demand is more often than not met through fossil fuel energy sources which along with polluting air and water – emit greenhouse gases that cause climate change.
In other words Bitcoins are contributing to the warming of the atmosphere without providing a significant public benefit in return.
