A Closer Look at the Environmental Impact of Bitcoin Mining
According to a new estimate, the Bitcoin network could be using at least as much energy as all of Ireland. That's because Bitcoin mining—the process by which Bitcoins are created and transactions tracked in a public ledger known as the blockchain—requires electricity. But no one knows exactly how much energy the secretive industry consumes. To help fill this gap, Alex De Vries, a blockchain specialist at PwC's Experience Center in the Netherlands, outlines a methodology to calculate just how much electricity the Bitcoin network uses in a year in a commentary in the journal Joule.
His initial estimate is jarring: At minimum, De Vries found, the network could be using 2. That number comes from estimating the number of devices connected to the Bitcoin network—which is estimated to have at least 10, nodes, but those nodes can be either single devices or a group of machines in a mining facility—and the processing efficiency of those machines.
However, this approach can only ever provide researchers with a minimum estimate, De Vries writes, "first of all because the network doesn't contain a single type of machine, but also because it doesn't take cooling requirements into account. As machines mine for Bitcoin, they can produce as much heat as a space heater.
Case in point: Circa , I briefly had a roommate in college who built a computer that mined Bitcoin and heated the living room of a small apartment through a Boston winter. Large-scale mining operations have to counter all that excess heat with cooling technology, which requires additional electricity. But Bitcoin mining companies are usually no more transparent about energy expenditures for cooling than they are about mining.
So De Vries turned to economics. More computational power means more Bitcoins, but also greater energy requirements, which cost mining operations money. Naturally, if the costs equal or outweigh the profits, mining Bitcoin no longer makes sense. De Vries used data on the cost and lifespan of mining machines from the manufacturer Bitmain, and electricity use estimates for the machines, to estimate when that equilibrium will be reached and how much electricity the Bitcoin network might be using at that point—a whopping 7.
The economic model could provide policymakers with important insights into a growing industry—especially as countries around the world attempt to scale back energy consumption to meet the goals of the Paris Agreement. But it still has its limitations. For one thing, Bitcoin mining machine manufacturers like Bitmain are pretty secretive with their data as well, which means De Vries estimates are still just best guesses.
For another, an economic model assumes that actors will behave rationally and get out of the game when the costs exceed profits, but that's not always how it works in the real world. Of course, all of this also depends on the price of Bitcoin, which is notoriously unstable. Depending on who you ask, Bitcoin is either spiraling or poised to re-bound , but it's also not the only cryptocurrency on the market anymore.

Bitcoin mining activity see infographic below is energy intensive — but no one yet truly knows exactly how much energy is consumed by the Bitcoin community. There are, however, well-researched estimates of the energy used to create bitcoins. Figures vary, but many articles often cite the estimate of Digiconomist — 32 terawatt hours TWh per year, with each Bitcoin transaction consuming kilowatt hours kWh. To put that into perspective, every mined bitcoin consumes about the same amount of power that an average home uses in nine days. In the world's conversation about energy, one point is beyond debate: Energy makes a vital contribution to people's quality of life, to society and to human progress. This is true today, and it will remain true in the future. That's why Energy Matters was created. We believe it's important to equip people with unbiased information so they may form opinions, join the conversation and feel confidence in the work and accomplishments of the energy sector. Energy Matters is an initiative that provides transparent information and perspective on energy. Here, we'll cover a range of topics: the scale of global energy; the ways energy is sourced and produced; current energy technology; forthcoming innovations; the world's future energy needs; and the sustainable sources of energy that will fill them.
Electricity needed to mine bitcoin is more than used by 'entire countries'
These are two possibly conflicting fascinations, as previously pointed out by Christopher Malmo here at Motherboard. That's because bitcoin is incredibly energy intensive: at the time of Malmo's piece, he calculated that a single bitcoin transaction requires as much electricity as the daily consumption of 1. As I have some experience in developing energy scenarios, I wanted to see how this could develop into the future. My findings weren't much more encouraging.
Bitcoin: ecco quanta energia elettrica consumano
The bitcoin network is burning more and more energy for mining bitcoins. The total power consumed by the bitcoin network has already crossed the consumption level. Last year, the electricity consumed by the network for mining bitcoins was estimated to be around 67 terawatt-hours TWh. The consumption this year has already surpassed that mark and by the end of , the mining looks set to have consumed 91TWh of energy — as much as Pakistan, according to a research report by Bloomberg. It noted that as the bitcoin price goes up, more bitcoin miners join the network with less energy-efficient machines to mine bitcoin that pushes the use of energy. The high use of electricity for mining bitcoin has also made it increasingly important to switch to low-carbon energy sources for electricity.
Bitcoin Miner Power Consumption: How Much Energy Do Bitcoin Miners Consume?
Energy consumption has become the latest flashpoint for cryptocurrency. Critics decry it as an energy hog while proponents hail it for being less intensive than the current global economy. This puts the bitcoin economy on par with the carbon dioxide emissions of a small, developing nation like Sri Lanka or Jordan. Jordan, in particular, is home to 10 million people. But CoinMetrics data indicates more than 1 million bitcoin addresses are active, daily, out of up to million accounts active in the past decade, as tallied by the exchange Crypto. Plus, many bitcoin mining businesses rely on environmentally friendly energy sources like hydropower and capturing natural gas leaks from oil fields. The best way to make cryptocurrency mining more eco-friendly is to support lawmakers that want to encourage mining in regions that already have underutilized energy sources. All of the top five bitcoin mining pools , consortiums for miners to cooperate for better profit margins, rely heavily on hydropower.

As cryptocurrency becomes mainstream, its carbon footprint can’t be ignored
RELATED VIDEO: How to calculate GPU mining rig power consumptionGreen bitcoin has been proposed as a way to counter the excessive energy consumption and CO2 emissions of cryptocurrencies. However, Martin C. Walker writes that the whole idea that you can create a green type of bitcoin that would work alongside non-green ones is hard to maintain. Though bitcoin has been criticised for many things over the years, including facilitating crime and operating as a giant Ponzi scheme, the price has increased so fast recently that it is increasingly hard for the conventional financial sector to ignore it. However, the excessive energy consumption and CO2 emissions of bitcoin are a major concern for investment managers under increasing pressure to demonstrate they follow environmental, social and governance ESG principles.

The bitcoin is a cryptocurrency that works based on a peer-to-peer network that currently includes about 12, validating computers. There is no central node. The file indicating the amount held in each bitcoin account is copied identically into the memory of each computer in the validator network. The network is not controlled by any authority.
