IF BITCOIN CONTINUES TO TAKE SO MUCH ENERGY 'IT WILL KILL THE PLANET'

  • by November 17, 2018

Bitcoin, the world’s most popular digital cryptocurrency, is celebrating its 10th birthday. It is also the subject of a new research paper that claims Bitcoin could become the worst contributor to climate change on the planet.

new paper published in the journal Nature Climate Change, suggests that, if Bitcoin is adapted at a similar pace that other technologies have been adapted, then its trajectory will result in it sucking up more energy than anything else in the world.

Without intervention, Bitcoin mining could alone be responsible for carbon emissions driving the earth to warm by two degrees Celsius by 2033, the paper claims. The two degree-increase is known to have the potential to be a cutoff for environmental health, with catastrophic consequences if and when we reach that level of warming.


Energy-intensiveness is integral to how Bitcoin works. Bitcoins can only come into existence if a computer “mines” them, which means the computer must solve complex math equations, sucking up electricity. Part of the economic draw of Bitcoin is that it cannot be produced easily or cheaply, meaning it is unlikely that it will be mined so quickly that it loses value. There is also a cap on Bitcoin production: there will only be 21 million in total.

Mining one bitcoin “could take as much energy in that transaction to power your house for months”, said Jon Truby, Director of the Centre for Law and Development at Qatar University. “Right now, that’s not sustainable.”


It is hard to predict the future of Bitcoin: it is highly volatile and is sometimes worth less than the amount of money it costs to mine. The difficulty of the equation that the computer has to solve can also make mining bitcoins take more energy. Many economists suggests that the value will increase, and it is possible that technology could also improve mining efficiency in the future. Some argue that cash is also environmentally destructive.

Alternatively, maybe mining Bitcoins will eventually become more efficient and use less energy. “The mining efficiency has been improving quite a lot,” Camilo Mora, lead author of the study, said. “That is because you make more money there. That is something that the mining companies have tried to push hard.”
