Bitcoin could cost us our clean-energy future

"Last week, the value of a single bitcoin broke the $10,000 barrier for the first time. Over the weekend, the price nearly hit $12,000. At the beginning of this year, it was less than $1,000.

If you had bought $100 in bitcoin back in 2011, your investment would be worth nearly $4 million today. All over the internet there are stories of people who treated their friends to lunch a few years ago and, as a novelty, paid with bitcoin. Those same people are now realizing that if they’d just paid in cash and held onto their digital currency, they’d now have enough money to buy a house."

"But the rise of bitcoin is also happening at a specific moment in history: Humanity is decades behind schedule on counteracting climate change, and every action in this era should be evaluated on its net impact on the climate. Increasingly, bitcoin is failing the test."

"In just a few months from now, at bitcoin’s current growth rate, the electricity demanded by the cryptocurrency network will start to outstrip what’s available, requiring new energy-generating plants. And with the climate conscious racing to replace fossil fuel-base plants with renewable energy sources, new stress on the grid means more facilities using dirty technologies. By July 2019, the bitcoin network will require more electricity than the entire United States currently uses. By February 2020, it will use as much electricity as the entire world does today."
