The decrease has been experienced broadly, in virtually all U.S. Source: Constructed by Lucas Davis at UC Berkeley using residential electricity consumption from EIA, and population statistics from the U.S. Consumption dipped significantly in 2012 and has remained flat, even as the economy has improved considerably. residential electricity consumption per capita 1990-2015. American households use less electricity than they did five years ago.
residential electricity consumption per capita increased 10-fold, an annual increase of 4% per year.īut that electricity trend has changed recently. As incomes have risen, we buy more food, live in larger homes, travel more, spend more on health care, and, yes, use more energy. Īmericans tend to use more and more of everything. According to Davis it is not clear yet whether household electricity use has peaked or will rise again in future. The reason may surprise you, notes Davis: it’s energy-efficient lighting. “In this world, with all these smart people, there has got to be a better solution,” said Larsen.Despite continued economic growth, American households use less electricity than they did five years ago, writes Lucas Davis of the Energy Institute at Haas School of Business.

Organizers are also taking legal action against proposed mining sites and using their large memberships to push bitcoin’s biggest investors and influencers to call for a code change. The campaign is launching with digital advertising in the Wall Street Journal, New York Times, Marketwatch, Politico, Facebook and other publications. “Bitcoin mining could be this endless monetization engine for fossil fuels. “Imagine the Saudis sitting on all that oil, which has a cost of about ½ cent per kilowatt hour – no renewable can match that,” Larsen said. One “nightmare scenario”, he said, is that the world does get to a renewable future in China, the US and EU but countries rich in fossil fuel switch to bitcoin mining to keep their operations running. “The minute that there is the opportunity to go to something dirty, which is what you are seeing, that is going to happen.” Without a change to the code, the fundamental problem will remain that bitcoin’s code “incentivizes maximum energy use”, said Chris Larsen, founder and executive chairman of crypto company Ripple and a climate activist. “Fossil fuel growth is outpacing renewable growth in bitcoin mining and that’s the fundamental challenge,” Brune said. But Brune said while such moves were “clearly well-intentioned”, adding “some boutique wind or solar operations powering a few high- profile mining operations” would not do enough to counter the environmental cost. Some bitcoin miners have recently begun powering their operations using renewable energy from wind and solar. “There’s no way we can reach our climate goals if we are reviving fossil fuel plants. We are seeing this all across the country,” said Brune.īrune added: “It’s particularly painful to see this in the electric sector because that is precisely the place where the US has made most of its progress in the last decade,” he said. Gas plants, which in many cases were increasingly economically uncompetitive, are also now being dedicated to bitcoin mining. “Coal plants which were dormant or slated to be closed are now being revived and solely dedicated to bitcoin mining.
The US now leads the world in cryptocurrency mining after China launched a crackdown on mining and trading last May. In part because of where the industry stands now but also because of our concerns about its growth,” said Michael Brune, campaign director and former executive director of Sierra Club. With the value and use of cryptocurrencies rising, the campaign’s organizers argue bitcoin must follow suit or find another, less energy intensive, method. In the proof of stake model, miners pledge their coins to verify transactions adding inaccurate information leads to penalties. Rival cryptocurrency ethereum is shifting to another system – “proof of stake” – that it believes will reduce its energy use by 99%. Proof of work is a way of checking that a miner has solved the extremely complex cryptographic puzzles needed to add to the bitcoin ledger.

The software code that bitcoin uses – known as “proof of work” – requires the use of massive computer arrays to validate and secure transactions.
