Crypto electricity use
The seemingly never-ending debate was at the forefront of cryptocurrency discussions for a large part of Bitcoin uses 0. The root of the problem is that those who oppose Bitcoin have argued that Bitcoin uses as much energy as all of Denmark, he said, but Denmark has a low population that doesn't use much energy, according to Novogratz. Denmark is the th largest country with a population of around 5. Albeit, Bitcoin does use a lot of electricity, but Novogratz said more and more miners are transitioning to green energy. It's just not true," he emphasized.

How to make cryptocurrency more sustainable
The most common method for producing crypto-assets requires enormous amounts of electricity and generates large CO2 emissions. Crypto-asset producers are keen to use more renewable energy, and they are increasing their presence in the Nordic region. Sweden needs the renewable energy targeted by crypto-asset producers for the climate transition of our essential services, and increased use by miners threatens our ability to meet the Paris Agreement. Energy-intensive mining of crypto-assets should therefore be prohibited.
The social benefit of crypto-assets is questionable. The Swedish Financial Supervisory Authority, like other international organisations such as the International Monetary Fund and the US Federal Reserve Board, considers that there are aspects of crypto-assets that are problematic. The consumer risks are significant, and crypto-assets are commonly used for criminal purposes such as money laundering, terrorist financing and ransomware payments.
Crypto-assets also have a significant negative impact on the climate as mining leads to both large emissions of greenhouse gases and threatens the climate transition that needs to happen urgently. This is alarming, and crypto-assets therefore need to be regulated. The University of Cambridge and Digiconomist estimate that the two largest crypto-assets, Bitcoin and Ethereum, together use around twice as much electricity in one year as the whole of Sweden.
Crypto-production's high energy consumption is due to its mining process, which is called proof of work. Anyone who wants to mine assets competes to solve an encryption puzzle, and the winner receives new crypto-assets as a reward.
The only way to solve the puzzle is by repeatedly running computer programs that guess the right answer. When a large number of crypto-producers' computers work simultaneously, the demand for electricity soars.
As the value of crypto-assets such as Bitcoin rises, more producers are incentivised to join the competition. This automatically increases the difficulty of the encryption puzzle. This in turn means that individual miners will require more electricity to solve the puzzle, and will therefore increase overall electricity consumption and carbon emissions. We see clearly that the more expensive Bitcoin becomes, the more emissions it generates.
Digiconomist estimates that crypto-assets at their current market value lead to release of up to million tonnes of CO2 in the atmosphere per year. To get a better sense of this number, we can compare it with emissions from long-distance flights. Using the aviation industry's own data from ICAO Carbon Emissions Calculator and adding the high elevation effect shows that the emissions from the two largest crypto-assets' today is equal million round-trip flights between Sweden and Thailand.
The reason for the industry's large carbon footprint is that the majority of crypto-production takes place in countries with low energy prices and a high share of fossil-dependent electricity production. Since the value of Bitcoin has increased so much, this has also extended the life of old fossil-based energy producers. Due to the increased focus on CO2 emissions and in light of China's recent Bitcoin prohibition, a greater number of crypto-producers are exploring the possibility of using renewable energy for mining.
Crypto-producers are therefore turning their attention to the Nordic region, where prices are low, taxes for mining-related activities are favourable, and there is good access to renewable energy.
We are already seeing crypto-producers establish themselves in northern Sweden. Between April and August this year, electricity consumption for Bitcoin mining in Sweden increased by several hundred per cent and now amounts to 1 TWh annually.
That is equal to the electricity of , Swedish households. If we were to allow extensive mining of crypto-assets in Sweden, there is a risk that the renewable energy available to us will be insufficient to cover the required climate transition that we need to make.
This energy is urgently required for the development of fossil-free steel, large-scale battery manufacturing and the electrification of our transport sector. Based on estimates from Cambridge University, it is currently possible to drive a mid-size electric car 1. This is the equivalent of forty-four laps around the globe. This is not a reasonable use of our renewable energy. Our conclusion is that policy measures are required to address the harms caused by the proof of work mining method.
It is important that both Sweden and the EU can use our renewable energy where it provides the greatest benefit for society as a whole. There are several different policy options available. For instance, Sweden and other countries could introduce a tax on the energy-intensive production of bitcoin. Another option is to communicate more widely around the climate problems related to crypto-assets, in the hope that this will lead to both producers and investors demanding a shift to mining methods that require less energy.
Given the rapid growth and demand for crypto-assets, neither of these options are likely to address the environmental harm we see from this mining method today.
The emissions need to stop here and now, and renewable energy needs to be used for the climate transition of essential services. There is a risk that these measures will lead to crypto-producers relocating to other countries, potentially resulting in overall higher emissions of carbon. But it is important that Sweden and the EU lead the way and set an example in order to maximize our chances of meeting the Paris Agreement.
We should also strongly encourage other countries and regions to follow suit. A ban on the proof of work mining method within the EU could be an important first step in a global move towards a greater use of more energy-efficient crypto mining methods.
It would also mean that our renewable energy is used as efficiently as possible in order to support the transition towards climate neutrality. Questions from the media are considered a high priority.

There are other methods for mining crypto-assets, that could also be used for Bitcoin and Ethereum, that are estimated to reduce energy consumption by Sweden to meanwhile introduce measures that halt the continued establishment of crypto-mining production using energy-intensive methods.

Scientists from the University of Cambridge Judge Business School have built an interactive analysis tool to calculate the real energy cost of bitcoin cryptocurrency. Using their energy use model, the researchers found that bitcoin mining uses more energy each year than the entire country of Argentina. Blockchain refers to the collective record called a ledger that stores cryptocurrency transactions, like a communal Excel spreadsheet. These volunteers are called miners, and the reward for volunteering their hardware is kickbacks in the form of more cryptocurrency.

Bitcoin will consume a ‘Pakistan’ worth of electricity in 2021
Joe Hernandez. A sign at a store in El Zonte, El Salvador, advertises that it accepts bitcoins for payment. The president of El Salvador announced Wednesday that the country's state-run geothermal energy utility would begin using power derived from volcanoes for Bitcoin mining. The announcement on social media came just hours after the Central American nation's congress voted to make the cryptocurrency an acceptable legal tender.

Congress Is Trying To Figure Out What To Do About Crypto's Colossal Carbon Footprint
Bitcoin is back in the spotlight these days thanks to some wild price movements and central bank meetings. But the higher the price goes, the more it exacerbates bitcoin's dark side: shocking levels of electricity consumption. In , I wrote that bitcoin had a big sustainability problem. Back then, each bitcoin transaction represented roughly enough electricity to power 1. Since it's been two years, it's time for an update. First, a caveat: it's impossible to know precisely how much electricity any given bitcoin transaction "consumes," but it's simple enough to estimate a plausible range of energy consumption for overall bitcoin mining. Mining secures transactions on the blockchain , a giant ledger of all completed transactions. It's worth looking at estimates for a per-transaction energy cost because we can compare that cost to existing payment systems.
Bitcoin is an energy hog: New numbers suggest how big a problem it is
Cryptocurrencies have been some of the most talked-about assets in recent months, with bitcoin and ether prices reaching record highs. These gains were driven by a flurry of announcements, including increased adoption by businesses and institutions. Lesser known, however, is just how much electricity is required to power the Bitcoin network.

Annualized Total Bitcoin Footprints. Single Bitcoin Transaction Footprints. Criticism and potential validation of the estimate is discussed here. The latter has been removed per October 1, Moreover, the energy used is primarily sourced from fossil fuels.
With more than 4, mineable coins and tokens in existence, which, if any, are the most sustainable cryptocurrencies? Are you a Dogecoin fan? This is because there are so many parameters at play. Many much smaller cryptocurrencies, for instance, naturally have a far lower energy footprint because they involve far fewer daily transactions compared to Bitcoin. Scale them up, however, and they may be just as bad, if not worse than the cryptocurrency we currently love to hate.
China is cracking down on bitcoin miners. The plan involves investigating power consumption of bitcoin miners to determine whether their use of free or cheap electricity use has distorted power prices in those areas. Most studies and anecdotal reporting state that China is home to a majority of bitcoin mining operations.
