Bitcoin mining and its energy footprint Abstract: Bitcoin is a digital cryptocurrency that has generated considerable public interest, including both booms in value and busts of exchanges dealing in Bitcoins. One of the fundamental concepts of Bitcoin is that work, called mining, must be done in checking all monetary transactions, which in turn creates Bitcoins as a reward.

Bitcoin Uses More Electricity Than Many Countries. How Is That Possible?

In our new series for the Future Citizen Institute we lay the focus on social implications of emerging practices from the fintech industry. The weekly published articles aim to inform an international audience with an interest in the evolution of financial technology and the economic, political, or philosophical meaning thereof.

In particular, applications of the blockchain technology, such as self-enforcing contracts or bitcoin mining, will be presented and cautiously discussed, to enable the reader the development of a holistic perspective. The first article introduces and explains key-terminology and is concerned with the comparatively high energy consumption of Bitcoin mining. Blockchain technology puts a different complexion on the world of accountancy and data transmission. A crucial downside is the energy intensity of the procedure behind the creation of the block chain.

The term Bitcoin mining refers to one step of the still young blockchain technology. Here, all participating computers are interconnected and configured to produce a unique numerical fingerprint. This fingerprint serves as verification of whichever bitcoin transaction is being carried out and needs to be created for each such transaction. As it is the case for all fingerprints, this numerical one is also unique and can only be generated by state-of-the-art computers.

This is because of two linked reasons:. First, in order to create — or rather find — the random numerical key, encrypted mathematical hash functions need to be written and run which already is highly energy consuming.

Secondly, the incentive for participants to provide the computational power necessary to verify and organise global bitcoin transactions is a remuneration in bitcoins — a currency per se. Consequently, fierce competition emerged with the goal to provide as many hashed blocks with the correct numerical value and time stamp validating the correctness of a large package of transactions as possible in order to get rewarded As a result, a single high-performance computer, i.

Since the number of Bitcoins is limited to 21 million and roughly The amount of electricity spent globally on the mining process is measured in terawatt hours, since the customary indication in kilowatt hours is no longer adequate.

Consequently, according to the above-mentioned Bitcoin Energy Consumption Index, Bitcoin mining — put into a country perspective — ranks 51 st , ahead of countries such as Singapore, Nigeria or Denmark. In fact, it consumes virtually fifty billion kilowatt-hours per year, roughly the same as the combined energy consumption of thirty-seven million Chinese households in the same period.

This is exacerbated by the scarcity of the good; with only 3. The website BitcoinEnergyConsumption. However, the statistics portal Statista presents significantly differing numbers; here we find a ratio closer to , indicating that almost thousand Visa transactions could be conducted with the amount needed for one Bitcoin transaction.

Considering these numbers, certain questions arise: Which are the ecological consequences of this praxis, in what way is crypto-mining affecting energy prices, How do we design the transactions to be more efficient.

Largest Bitcoin Mining Farms in the World

The Bitcoin mining industry in Texas currently consumes around to 1, MW of power. ERCOT anticipates, as reported by Bloomberg, that that demand could increase as much as fivefold by and has planned an additional 3, to 5, MW. It is worth noting that Texas has emerged as a Bitcoin mining hub after the Chinese government de-legalised all crypto-related activities including trading and mining, earlier this year.

Bitcoin's electricity use eight times higher than Google's and Facebook's combined

Today, Bitcoin consumes as much energy as a small country. This certainly sounds alarming — but the reality is a little more complicated. How much energy does an industry deserve to consume? Right now, organizations around the world are facing pressure to limit the consumption of non-renewable energy sources and the emission of carbon into the atmosphere. As cryptocurrencies, and Bitcoin in particular, have grown in prominence, energy use has become the latest flashpoint in the larger conversation about what, and who, digital currencies are really good for. On the face of it, the question about energy use is a fair one. This certainly sounds like a lot of energy. But how much energy should a monetary system consume? How you answer that likely depends on how you feel about Bitcoin. If you believe that Bitcoin offers no utility beyond serving as a ponzi scheme or a device for money laundering , then it would only be logical to conclude that consuming any amount of energy is wasteful.

Environmental Concerns Arise Over Energy Needed To Mine Bitcoin

If Bitcoin were a country, it would rank in the top 30 worldwide for energy use. The blockchain technology that underlies it, meanwhile, could be the key to a greener future.

Why Is Bitcoin Mining So Energy Intensive?

Bitcoin mining consumes electricity in a uniquely flexible way, making the process highly suitable for stabilizing electricity systems through a mechanism called demand response. The current transition from fossil fuels to renewable energy reduces the flexibility in electricity systems globally. The need for demand response is therefore increasing. In this blog post, I explain why we desperately need to increase the flexibility in electricity systems and evaluate if bitcoin mining can be a solution. In electricity systems, supply and demand must be balanced in real-time since electricity cannot easily be stored. The electricity supply going into the system must equal the demand at all times.

Bitcoin consumption beats Argentina's annual energy use

Crypto critics often cite the environmental impact of Bitcoin mining as a major reason for concern, but why exactly is mining so energy intensive? And what exactly is Bitcoin mining in the first place? Simply put, Bitcoin mining is the process by which more Bitcoin is created. Bitcoin is a decentralized currency, meaning it is not overseen by any traditional governing body. In order to prevent theft and fraud, every computer in the Bitcoin network has a full list of Bitcoin transactions called the blockchain. Every time an individual sends Bitcoin to another, the majority of computers in the network must verify the transaction. Blocks are added to the blockchain by whichever computer in the network is able to find a unique key — the answer to a mathematical problem — first.

Energy Consumption of Bitcoin Mining

Bitcoin is finding its way into more and more portfolios, and the acceptance of cryptocurrencies as an alternative asset class is rising. Companies are adding Bitcoin to their treasury reserve assets, and notable macro investors and asset managers have formulated their investment thesis for Bitcoin or already decided to allocate part of their portfolios to it. As Bitcoin grows, so does the focus on the externalities of the cryptocurrency, most prominently its energy consumption. However, these comparisons depend greatly on the parameters chosen for the estimation.

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.

What if you could substitute a renewable battery powered motor for the internal combustion engine just twelve years after its invention? At minimum, we would not be faced with the challenge of limiting greenhouse gas emissions. For all of the benefits the internal combustion engine has brought humanity, its environmental consequences are not among them.
