Bitcoin Energy Consumption Is Far More Efficient and Greener Than Today’s Banking System – Mining Bitcoin News
Bitcoin Energy Consumption Is Far More Efficient and Greener Than Today’s Banking System
While bitcoin and a variety of digital currencies have swelled in value, a number of critics have spread fear, uncertainty, and doubt (FUD) in regard to the energy consumption proof-of-work (PoW) cryptocurrencies leverage to produce new units of currency. Just recently the software engineer Stephen Diehl expressed his dissatisfaction over the environmental cost of bitcoin. However, cryptocurrency supporters believe Diehl failed to mention the amount of renewable energy used by a great number of mining facilities, alongside the insurmountable cost to operate today’s banking system.
Bitcoin’s Waste of Energy Argument Is a Fool’s Errand
The latest hot topic within the cryptocurrency industry is the topic of Bitcoin’s proof-of-work (PoW) energy consumption, and whether or not the consumption is efficient. The conversation was sparked by a number of articles published during the last year, alongside software engineer Stephen Diehl’s recent critique of the network’s power consumption.
Besides the fact that Diehl considers the crypto asset to be “a giant smoldering Chernobyl,” he also said that “bitcoin economics [is] a pyramid-shaped investment scheme backed by the collective delusion that value can [be] created out of nothing by convincing greater fools to buy it after you do.”
Diehl’s criticism toward Bitcoin’s energy consumption is filled with obvious fallacies, but he also doesn’t realize how Satoshi’s cryptocurrency network is more energy-efficient than most think. Diehl and many others, also fail to recognize the cost to maintain today’s banking system, which consists of a great number of terawatts dedicated to servers, branches, and automated teller machines.
1/ Bitcoin’s energy consumption is not “wasteful.”
– It is much more efficient than existing financial systems
– No one has the moral authority to tell you what is a good or bad use of energy (ex: watching the Kardashians)
Let’s debunk this FUD?

Bitcoin Electricity Consumption Index Discrepancies
Most of the consumption data stemming from the BTC network is derived from the Cambridge Bitcoin Electricity Consumption Index (CBECI). Interestingly enough analysts and mainstream media reporters also reference the digiconomist.net bitcoin energy consumption index as well. Unfortunately, both CBECI and digiconomist.net’s annualized consumption of terawatt per hour (TWh) data has a very large discrepancy.
The digiconomist.net stats show the BTC network captures 77.78 TWh, while CBECI indicates the network is 111.08 TWh. That is a huge variance (44% difference) when attempting to estimate the data consumption of the crypto asset’s network. Yet, these are the most leveraged sources used by bitcoin naysayers who say BTC’s electrical consumption is a ‘waste’ without any shame.
Further, we don’t even know how accurate the CBECI data is because a team member from the Cambridge Centre for Alternative Finance (CCAF) recently explained to news.Bitcoin.com that the CBECI map is not up-to-date and will be updated in 2021. This has led to numerous reports stating that China captures 65% of the Bitcoin mining hashrate, which may be entirely inaccurate. In July 2020, a hashrate report written by Bitooda said China was steadily losing its concentration of bitcoin hashpower and the country dropped to 50%.
It is far more likely, that CBECI’s theoretical lower bound estimate for the BTC network’s energy consumption is more accurate. This theoretical lower bound estimate is around 4.6 gigawatts or 39.3 TWh annualized on January 19, 2021. Moreover, there are countless rebuttals and data points that show people complaining about Bitcoin’s energy consumption are overreacting.
we had the exact same debates about the perceived ‘costliness’ of the gold standard
I would direct the energy crew to go read those rebuttals instead of boring us with 100 yr-old arguments

Studies Show Over 75% of Cryptocurrency Miners Leverage Renewable Energy Sources
For instance, the anti-bitcoin environmentalists do not weigh the fact that much of the PoW mining industry uses renewable energy sources like hydropower, wind, solar, and geothermal energy. There are a number of reports that show over 70% of crypto miners use a mix of renewable energy to power facilities across the world. There is also abundant efforts dedicated to energy cogeneration as well.
The 2020 third Global Cryptoasset Benchmarking Study by the University of Cambridge also indicates that 76% of digital currency miners use renewable power sources. Backing up this data is a report from Deutsche Bank Research, the Chinese National Energy Agency, Morgan Stanley, and Coinshares. The report from these four organizations highlights that “78% of Bitcoin’s electricity usage is from renewables.”
There are countless reminders and real-world examples of bitcoin miners using a far more efficient means of electric use than all of the financial systems on the planet. Two years ago, Bill Tai, an investor and board director of Bitfury, detailed that Satoshi is smiling because of the green energy use bitcoin miners use today.
“It’s been clear to me for years now, that mining of Bitcoin and other ‘proof-of-work’ based cryptocurrencies are driving positive change in the underlying infrastructure of energy production — at an accelerating rate,” Tai explained at the time. The investor is also the chairman of Hut8’s board and he said the company has a “policy to ‘be green’ as we build.” Tai detailed that the most efficient sources of electrical power are not fossil fuel-based in order to scale, but the marginal costs of water, solar, and wind-based energy, Tai stressed.
Delivery Trucks, Servers, Branches, ATMs, and the Insurmountable Cost of the Modern Banking System
Then ultimately there’s the cost of the modern banking system, something that bitcoin naysayers never account for when they criticize the crypto’s energy consumption. There is a great number of articles and statistics that indicate the current banking system uses well over 140 TWh a year. In one study, Katrina Kelly-Pitou, a researcher who “studies clean energy technology, specifically the transition toward decarbonized energy systems” says the energy conversation surrounding bitcoin is “oversimplified.”
Furthermore, the researcher stressed that “Bitcoin’s energy consumption isn’t as bad as you think.” Then the Hacker Noon contributor, Carlos Domingo, called the comparison of bitcoin’s electrical usage to Visa’s a complete “fallacy.”
Domingo said:
Stop complaining about Bitcoin and start complaining about Xmas lights.
Despite the Fact That ‘the Cost of Bitcoin Mining Has Never Really Increased,’ Cancel Culture Pundits Want to ‘Criminalize Bitcoin’
This past October, the researchers Yo-Der Song and Tomaso Aste, published a report which highlights that the cost of bitcoin mining “has never really increased.” In the paper, Aste and Song detail that the Bitcoin network consumes a lot of energy, but the researchers still manage to estimate the “lower bound for the global mining energy cost for a period of 10 years from 2010 to 2020.”
“Despite a 10-billion-fold increase in hashing activity and a 10-million-fold increase in total energy consumption, we find the cost relative to the volume of transactions has not increased nor decreased since 2010,” the paper notes.
The researchers add:
This is consistent with the perspective that, in order to keep the Blockchain system secure from double-spending attacks, the proof of work must cost a sizable fraction of the value that can be transferred through the network. We estimate that in the Bitcoin network this fraction is of the order of 1%.
It is clear that the bitcoin mining industry is not as wasteful as the current banking system filled with not only servers, ATMs, and branches, but it is also free of rampant fraud and manipulation as well. Despite this, members of today’s woke crowd and cancel culture want to “criminalize bitcoin,” because it is allegedly “grotesquely damaging to the environment.” As usual, these critics are filled with emotional opinions and weak virtue signals, without a whole lot of facts to back them up.

How to Help Someone Having a Panic Attack | POPSUGAR Fitness
If you have a friend or family member who experiences panic attacks, it’s natural to feel overwhelmed and helpless if it happens in your presence. Like any other mental health condition, it’s impossible to truly understand what a panic attack feels like unless you’ve experienced one yourself — but that doesn’t mean you can’t help your loved one through it.
By definition, a panic attack is a “sudden episode” in which a person experiences intense fear despite not being in any sort of danger. The fear manifests itself physically, and people who experience panic attacks often feel as though they’re having a heart attack or even dying. Here are some strategies to help a loved one through it.
1. Do a Grounding Exercise Together
Doreen Marshall, PhD, licensed psychologist and vice president of mission engagement at the American Foundation For Suicide Prevention, told POPSUGAR that the first step is to help the person “ground” themself and connect to the present moment. “Since panic attacks have a beginning, middle, and end, when someone is in the moment of an attack, encourage them to use mindfulness techniques or deep breathing exercises to help reset their nervous system,” Dr. Marshall said.
You can help ground someone by getting them to focus their attention on their immediate physical surroundings. For example, Dr. Marshall recommends having the person focus on a nearby object for 10 seconds or name five objects they notice around them. “It can also help to have the person make physical contact with a nearby object, such as putting their hands on a table or a chair or running their hands under cold water to help ground them,” she said.
2. Help Them Regulate Their Breathing
A panic attack makes it difficult to breathe, which is why the person may feel like they’re having a heart attack or dying. David Rakofsky, PsyD, licensed clinical psychologist and president of Wellington Counseling Group in Chicago, told POPSUGAR the best way to help a person regulate their breathing is to breathe with them. “By the time a person is in full panic mode, their blood gasses have likely shifted from an over-abundance of oxygen, which can fuel the accelerating state of the panic,” Dr. Rakofsky explained. “By regulating breath, you start to reverse this cycle.”
Dr. Rakofsky recommends the “times two” rule, which means that for every second you breathe air in, you double it on the way out. “Always keep in mind [that] a person in panic or in a heightened state of anxiety will not be able to take in a lot of air since there is a feeling of constriction in the chest,” he said. For this reason, Dr. Rakofsky says to start small and then work your way up to taking longer, deeper breaths together.
3. Know What Not to Say
“Avoid phrases that could provoke more panic and come off as dismissive, shaming, or blaming,” Dr. Marshall said. For example, you shouldn’t tell someone who’s experiencing a panic attack to calm down. Instead, use phrasing that shows you’re focused on listening to the person and helping them get through the panic attack, like “I’m here with you,” “Concentrate on your breathing,” or “Stay in the present.”
Dr. Rakofsky also emphasized the importance of never telling a person that the panic attack is all in their head. “The feeling of invalidation and psychological invisibility that comes with being told this is absolutely crushing and likely to bring about a greater state of panic and distress,” Dr. Rakofsky told POPSUGAR, noting that it also increases distrust and a lack of hope that they’ll find real, helpful treatment for their panic attacks.
“Once the panic attack is over, then you can help them address what may have contributed to the panic attack and seek professional help,” Dr. Marshall said.
4. Encourage Them to Seek Professional Help
If a person has panic attacks and isn’t receiving mental health treatment from a therapist and psychiatrist, encourage them to seek help from a professional who has experience treating panic and anxiety disorders. “Connecting with a mental health professional can help someone who experiences a panic attack or attacks have access to a resource who can help determine what’s happening in the moment as well as manage episodes over time,” Dr. Marshall said.

Regular exercise offers stronger mental health benefits than cardiorespiratory fitness, study finds
A Swedish study published in Mental Health and Physical Activity has shed light on the well-known link between exercise and mental health. The researchers found that, when accounting for sedentary behavior, cardiorespiratory fitness does not appear to improve anxiety and depressive symptoms, while frequency of exercise does.
The link between exercise and mental health has been well-documented, and yet findings are limited when it comes to the type of physical activity that is most beneficial. The literature has yet to establish the relative importance of the frequency, intensity, and duration of exercise. As study authors Mats Hallgren and his team say, it is also unclear how cardiorespiratory fitness (CRF) relates to mental health.
CRF refers to the strength of the body’s circulatory and respiratory response to physical activity, and it tends to improve with regular exercise. In their study, Hallgren and his team set out to disentangle the relative importance of CRF and exercise frequency in the prevention of mental health symptoms. As the researchers say, filling in these gaps in research can help improve the design of exercise-based prevention strategies for mental health.
The researchers analyzed data from a general health assessment that was administered to a large number of Swedish employees. The sample was made up of 36,595 middle-aged men and women with an average age of 41. The questionnaires asked respondents how many times a week they had exercised in the past 30 days and how often they had experienced “worry, depressed mood or anxiety.” They also completed a test of cardiorespiratory fitness on a stationary bicycle and were then classified as either low, medium or high CRF.
First, the researchers found evidence that more frequent exercise was linked to improved mental health. Respondents who reported exercising at least 1-2 times a week were less likely to report symptoms of depression and anxiety, even after accounting for sedentary behavior — which was measured as the amount of leisure time participants reported spending sitting still.
As the researchers explain, sedentary behavior appears to play an important role in the link between exercise and mental health. Another study led by Hallgren found evidence that passive sedentary behaviors, such as TV-watching, increase depressive symptoms while mentally-active sedentary behaviors may actually prevent them.
Interestingly, cardiorespiratory fitness appeared to be less important when it came to the prevention of mental health symptoms. While respondents in the medium and high CRF groups reported fewer symptoms of depression and anxiety, this effect disappeared when sedentary behavior was taken into account.
“Taken together,” Hallgren and colleagues report, “this suggests that high CRF may not be necessary to prevent common mental health symptoms. Instead, regular participation in a preferred form of structured exercise may be of greater relative importance.”
The researchers discuss the possibility that the impact of cardiorespiratory fitness may only be relevant when comparing people with very low CRF levels to those with higher levels. Previous research suggests that CRF appears to be most beneficial to somatic health when looking at improvements among those with low fitness levels. It could be that the current study’s sample, which was made up exclusively of employed persons, did not include enough people with low fitness levels to capture such an effect.
A substantial limitation was that symptoms of depression and anxiety were measured using a single item, and the researchers stress that this measure does not reflect a diagnosis of depression or anxiety. Moreover, symptoms of anxiety and symptoms of depression are distinct and would be better assessed separately in future studies.
The researchers conclude that regular exercise may be enough to lower anxiety and depressive symptoms among most people, while it may be useful to encourage exercises that boost CRF among people with particularly low levels of fitness.
The study, “Associations of exercise frequency and cardiorespiratory fitness with symptoms of depression and anxiety – a cross-sectional study of 36,595 adults”, was authored by Mats Hallgren, Aaron Kandola, Brendon Stubbs, Thi-Thuy-Dung Nguyen, Peter Wallin, Gunnar Andersson, and Elin Ekblom-Bak.
