Italy is considering introducing an installed capacity cap for solar power incentives in its new decree on renewable energy, government and industry sources state.

The government, which has decided to scrap the existing generous solar incentive scheme from June, has been drafting a new support scheme.

"We have spoken to the Industry ministry and the feeling is it might introduce a cap on installed capacity, though the decree has not been finalized," a source at one of Italy's energy associations said.

Investors fear an annual cap on incentivized capacity could slow down the country's solar market.

Just recently a junior minister said the government aimed to complete the renewable energy decree by now, but the sources said discussions will require a few more days.

A government source told Reuters the decree was still in the works. When completed it needs to be signed by the Industry and Environment ministries but then needs to go before a committee of representatives of regional governments for its opinion.

The committee is due to meet on April 20 though as yet no agenda has been set, a spokeswoman for the body said.

Solar incentives are paid for by consumers in their energy bills and the government is seeking to lower these costs.

In March a trade union official, after a meeting with the government, told Reuters that Rome was considering capping the overall money it spends on solar incentives every year rather than using an actual installation cap.

But two industry sources said the government is now leaning more toward introducing a yearly cap on installed capacity.

La Repubblica newspaper, citing the latest version of the draft decree, said the government was considering reintroducing a cap on installed capacity of 1550-1800 megawatts for 2011 and up to 2,800 megawatts in 2012.

The article said incentives for solar power generation in 2011 would be cut by 25 percent immediately with an 8 percent cut in 2012.

"I don't think the final version is ready yet. We are proposing for 2012 a 5 percent cut for plants under 1 megawatt and a 10 percent cut for plants over 1 megawatt," GIFI President Valerio Natalizia told Reuters.

Italy's biggest solar industry body GIFI is a key party in talks with the government on new incentives. GIFI has also proposed the tariffs be reduced on an annual basis, under a German model, from 2012.

Italy's solar sector, among the biggest in Europe, has boomed since 2007, when some of Europe's most generous production incentives were launched.

It has attracted the world's biggest photovoltaic module makers such as China's Suntech Power Holdings Co, Trina, Yilgli Green Energy and U.S. firm First Solar.

Italy's biggest renewable operator is Enel Green Power while utilities such as Edison and CIR energy unit Sorgenia have renewable businesses.

Barakah Unit 1 reaches 100% power as it steps closer to commercial operations, due to begin early 2021

Barakah Unit 1 100 Percent Power signals the APR-1400 reactor delivering 1400MW of clean baseload electricity to the UAE grid, advancing decarbonisation, reliability, and Power Ascension Testing milestones ahead of commercial operations in early 2021.

 

Key Points

The milestone where Unit 1 reaches full 1400MW output to the UAE grid, providing clean, reliable baseload electricity.

✅ Delivers 1400MW from a single generator to the UAE grid

✅ Enables clean, reliable baseload power with zero operational emissions

✅ Completes key Power Ascension Testing before commercial operations

 

The Emirates Nuclear Energy Corporation, ENEC, has announced that its operating and maintenance subsidiary, Nawah Energy Company, Nawah, has successfully achieved 100% of the rated reactor power capacity for Unit 1 of the Barakah Nuclear Energy Plant. This major milestone, seen as a crucial step in Abu Dhabi towards completion, brings the Barakah plant one step closer to commencing commercial operations, scheduled in early 2021.

100% power means that Unit 1 is generating 1400MW of electricity from a single generator connected to the UAE grid for distribution. This milestone makes the Unit 1 generator the largest single source of electricity in the UAE.

The Barakah Nuclear Energy Plant is the largest source of clean baseload electricity in the country, capable of providing constant and reliable power in a sustainable manner around the clock. This significant achievement accelerates the decarbonisation of the UAE power sector, while also supporting the diversification of the Nation’s energy portfolio as it transitions to cleaner electricity sources, similar to the steady development in China of nuclear energy programs now underway.

The accomplishment follows shortly after the UAE’s celebration of its 49th National Day, providing a strong example of the country’s progress as it continues to advance towards a sustainable, clean, secure and prosperous future, having made the UAE the first Arab nation to open a nuclear plant as it charts this path. As the Nation looks towards the next 50 years of achievements, the Barakah plant will generate up to 25 percent of the country’s electricity, while also acting as a catalyst of the clean carbon future of the Nation.

Mohamed Ibrahim Al Hammadi, Chief Executive Officer of ENEC said: "We are proud to deliver on our commitment to power the growth of the UAE with safe, clean and abundant electricity. Unit 1 marks a new era for the power sector and the future of the clean carbon economy of the Nation, with the largest source of electricity now being generated without any emissions. I am proud of our talented UAE Nationals, working alongside international experts who are working to deliver this clean electricity to the Nation, in line with the highest standards of safety, security and quality." Nawah is responsible for operating Unit 1 and has been responsible for safely and steadily raising the power levels since it commenced the start-up process in July, and connection to the grid in August.

Achieving 100% power is one of the final steps of the Power Ascension Testing (PAT) phase of the start-up process for Unit 1. Nawah’s highly skilled and certified nuclear operators will carry out a series of tests before the reactor is safely shut down in preparation for the Check Outage. During this period, the Unit 1 systems will be carefully examined, and any planned or corrective maintenance will be performed to maintain its safety, reliability and efficiency prior to the commencement of commercial operations.

Ali Al Hammadi, Chief Executive Officer of Nawah, said: "This is a key achievement for the UAE, as we safely work through the start-up process for Unit 1 of the Barakah plant. Successfully reaching 100% of the rated power capacity in a safe and controlled manner, undertaken by our highly trained and certified nuclear operators, demonstrates our commitment to safe, secure and sustainable operations as we now advance towards our final maintenance activities and prepare for commercial operations in 2021." The Power Ascension Testing of Unit 1 is overseen by the independent national regulator – the Federal Authority for Nuclear Regulation (FANR), which has conducted 287 inspections since the start of Barakah’s development. These independent reviews have been conducted alongside more than 40 assessments and peer reviews by the International Atomic Energy Agency, IAEA, and World Association of Nuclear Operators, WANO, reflecting milestones at nuclear projects worldwide that benchmark safety and performance.

This is an important milestone for the commercial performance of the Barakah plant. Barakah One Company, ENEC’s subsidiary in charge of the financial and commercial activities of the Barakah project signed a Power Purchase Agreement, PPA, with the Emirates Water and Electricity Company, EWEC, in 2016 to purchase all of the electricity generated at the plant for the next 60 years. Electricity produced at Barakah feeds into the national grid in the same manner as other power plants, flowing to homes and business across the country.

This milestone has been safely achieved despite the challenges of COVID-19. Since the beginning of the global pandemic, ENEC, and subsidiaries Nawah and Barakah One Company, along with companies that form Team Korea, including Korea Hydro & Nuclear Power, with KHNP’s work in Bulgaria illustrating its global role, have worked closely together, in line with all national and local health authority guidelines, to ensure the highest standards for health and safety are maintained for those working on the project. ENEC and Nawah’s robust business continuity plans were activated, alongside comprehensive COVID-19 prevention and management measures, including access control, rigorous testing, and waste water sampling, to support health and wellbeing.

The Barakah Nuclear Energy Plant, located in the Al Dhafra region of the Emirate of Abu Dhabi, is one of the largest nuclear energy new build projects in the world, with four APR-1400 units. Construction of the plant began in 2012 and has progressed steadily ever since. Construction of Units 3 and 4 are in the final stages with 93 percent and 87 percent complete respectively, benefitting from the experience and lessons learned during the construction of Units 1 and 2, while the construction of the Barakah Plant as a whole is now more than 95 percent complete.

Once the four reactors are online, Barakah Plant will deliver clean, efficient and reliable electricity to the UAE grid for decades to come, providing around 25 percent of the country’s electricity and, as other nations like Bangladesh expand with IAEA assistance, reinforcing global decarbonisation efforts, preventing the release of up to 21 million tons of carbon emissions annually – the equivalent of removing 3.2 million cars off the roads each year.

Texas Weighs Electricity Market Reforms To Avoid Blackouts

Texas PUC Electricity Market Reforms aim to boost grid reliability, support ERCOT resilience, pay standby generators, require capacity procurement, and mitigate blackout risk, though analysts warn higher consumer bills and winter reserve margin deficits.

 

Key Points

PUC proposals to bolster ERCOT reliability via standby capacity, capacity procurement, and measures to reduce blackout risk.

✅ Pays generators for standby capacity during grid stress

✅ Requires capacity procurement to meet forecast demand

✅ Could raise consumer bills despite reliability gains

 

The Public Utility Commission of Texas is discussing major reforms to the state’s electricity market with the purpose to avoid a repeat of the power failures and blackouts during the February 2021 winter storm, which led to the death of more than 100 people and left over 11 million residents without electricity for days.

The regulator is discussing at a meeting on Thursday around a dozen proposals to make the grid more stable and reliable in case of emergencies. Proposals include paying power generators that are on standby when the grid needs backup, and requiring companies to pre-emptively buy capacity to meet future demand.

It is not clear yet how many and which of the proposals for electricity market reforms PUC will endorse today, while Texans vote on funding to modernize electricity generation later this year.

Analysts and consumer protection bodies warn that the measures will raise the energy bills for consumers, as some electricity market bailout ideas shift costs to ratepayers as well.

“Customers will be paying for more, but will they be getting more reliability?” Michael Jewell, an attorney with Jewell & Associates PLLC who represents clients at PUC proceedings, told Bloomberg.

“This is going to take us further down a path that’s going to increase cost to consumers, we better be darn sure these are the right choices,” Tim Morstad, Associate State Director, AARP Texas, told FOX 4 NEWS.

Last month, a report by the North American Electric Reliability Corp warned that the Texas power grid remained vulnerable to blackouts in case of a repeat of this year’s February Freeze.

Beyond Texas, electricity blackout risks have been identified across the U.S., underscoring the stakes for grid planning.

According to the 2021-2022 Winter Reliability Assessment report, Texas risks a 37-percent reserve margin deficit in case of a harsh winter, with ERCOT moving to procure capacity to address winter concerns, NERC said.

A reserve margin is the reserve of power generation capacity comparative to demand. The expected reserve margin for Texas for this winter, according to NERC, is 41.9 percent. Yet if another cold spell hits the state, it would affect this spare capacity, pushing the margin deeply into negative territory.

Don't be taken in by scammers threatening to shut off electricity: Manitoba Hydro

Manitoba Hydro Phone Scam targets small businesses with disconnection threats, prepaid card payments, caller ID spoofing, phishing texts, and door-to-door fraud; hang up, verify your account directly, and never share banking information.

 

Key Points

A scam where callers threaten disconnection and demand prepaid cards; verify account status directly with Manitoba Hydro.

✅ Hang up and call Manitoba Hydro at 1-888-624-9376 to verify.

✅ Never pay by prepaid cards, gift cards, or crypto.

✅ Hydro will not cut power on one-hour notice.

 

Manitoba Hydro is warning customers, particularly small business owners, to be wary of high-pressure scammers, as Ontario utilities warn of scams in other provinces, threatening to shut off their electricity.

The callers demand the customer to make immediate payment by a prepaid card. Often, the calls are made in the middle of the day at a busy time, frightening the customer with aggressive threats about disconnection, as hydro disconnections have made headlines elsewhere, says hydro spokesman Bruce Owen.

"They tell them 'we have a truck on the way to cut off your power. If you don't pay in the next hour you're out of luck,'" he said.

"And because these folks have inventory in freezers and they have customers … they're willing to fork over several hundred or even several thousand dollars on a prepaid card to somebody they don't know to keep the lights on."

Maybe the business owners can't recall, with everything happening, including discussions about Hydro One peak rates in Ontario, if they've made their payments on time. They start second-guessing and believing the person on the other line, Owen says.

And they worry about losing thousands of dollars in business if they lose power. So they're more than willing to run out to a store, buy a prepaid debit card and provide the number to the caller.

"Their goal is to manipulate you into sending money before you figure out it's a scam," said Chris McColm, hydro's security and investigations supervisor. "These people are crooks and you should hang up on them."

For any customers that are in arrears, hydro will work with them to resolve the issue, Owen said.

"We do not have to take that extreme measure of cutting off or disconnecting anybody. That's not the business we're in — we don't strong arm people that way," he said.

"Anybody who's threatening to cut off your power with an hour or half-an-hour notice, well it's it's no better than someone waiting around the corner, waiting the club you over the head in the dark of night. That's what they are."

 

Fraud reports soar

The power utility has recorded a nearly-300 per cent jump in the number of fraud-related complaints this year over 2017. There have been 862 phone, text and e-mail scams and that could still go much higher.

The current statistics from 2018 have only calculated up to Oct. 31. In 2017, there were 221.

That jump in numbers doesn't necessarily mean there are more scammers out there.

It could simply mean people are finally getting wise to fraudsters and reporting it more, Owen says.

"At the same token, we don't hear of everybody who's been taking advantage of because once they've found out that they've been hoodwinked they don't want to tell anybody because they're so embarrassed," he said.

"These scammers can be very convincing and anyone can be victimized," McColm said.

If you are able to think clearly when some high-pressure caller gets you on the line, Owen suggests asking a few simple questions to challenge their legitimacy:

  • What street am I on?
  • What does my business look like? 
  • What's the weather outside right now?

Phone scammers can falsify their caller ID information to make it appear they're calling from a local number, but what you'll find is most of them aren't in Winnipeg or Manitoba and likely not even this country or continent, Owen says.

The key to being safe is simply to never give out banking information, Owen says. It's a message that has been stressed for years and 80-90 per cent of people understand it, but it's that other 10-20 per cent that are still being victimized.And it's not just phone calls. Many other fraud-related complaints to Manitoba Hydro this year concerned unsolicited text messages to customers saying they had been overbilled, or faced retroactive charges elsewhere, and were eligible for a refund.

This scam is also aimed at getting a customer's personal banking information, under the guise of having money put back into their account.

Also, many people, especially seniors living alone, continue to be targeted by aggressive door-to-door fraudsters, and cases like the electricity theft ring in Montreal underscore the risks, McColm says. However, he adds, hydro employees always display photo ID and will never demand to come into a home. 

If you're unsure whether a phone call, text or email is real or a scam, contact Manitoba Hydro at 1-888-624-9376.

More pylons needed to ensure 'lights stay on' in Scotland, says renewables body

Scottish Renewable Grid Upgrades address outdated infrastructure, expanding transmission lines, pylons, and substations to move clean energy, meet rising electricity demand, and integrate onshore wind, offshore wind, and battery storage across Scotland.

 

Key Points

Planned transmission upgrades in Scotland to move clean power via new lines and substations for a low-carbon grid.

✅ Fivefold expansion of transmission lines by 2030

✅ Enables onshore and offshore wind integration

✅ New pylons, substations, and routes face local opposition

 

Renewable energy in Scotland is being held back by outdated grid infrastructure, industry leaders said, with projects stuck on hold underscoring their warning that new pylons and power lines are needed to "ensure our lights stay on".

Scottish Renewables said new infrastructure is required to transmit the electricity generated by green power sources and help develop "a clean energy future" informed by a broader green recovery agenda.

A new report from the organisation - which represents companies working across the renewables sector - makes the case for electricity infrastructure to be updated, aligning with global network priorities identified elsewhere.

But it comes as electricity firms looking to build new lines or pylons face protests, with groups such as the Strathpeffer and Contin Better Cable Route challenging power giant SSEN over the route chosen for a network of pylons that will run for about 100 miles from Spittal in Caithness to Beauly, near Inverness.

Scottish Renewables said it is "time to be upfront and honest" about the need for updated infrastructure.

It said previous work by the UK National Grid estimated "five times more transmission lines need to be built by 2030 than have been built in the past 30 years, at a cost of more than £50bn".

The Scottish Renewables report said: "Scotland is the UK's renewable energy powerhouse. Our winds, tides, rainfall and longer daylight hours already provide tens of thousands of jobs and billions of pounds of economic activity.

"But we're being held back from doing more by an electricity grid designed for fossil fuels almost a century ago, a challenge also seen in the Pacific Northwest today."

Investment in the UK transmission network has "remained flat, and even decreased since 2017", echoing stalled grid spending trends elsewhere, the report said.

It added: "We must build more power lines, pylons and substations to carry that cheap power to the people who need it - including to people in Scotland.

"Electricity demand is set to increase by 50% in the next decade and double by mid-century, so it's therefore wrong to say that Scottish households don't need more power lines, pylons and substations.

"We need them to ensure our lights stay on, as excess solar can strain networks in the same way consumers elsewhere in the UK need them.

"With abundant natural resources, Scotland's home-grown renewables can be at the heart of delivering the clean energy needed to end our reliance on imported, expensive fossil fuel.

"To do this, we need a national electricity grid capable of transmitting more electricity where and when it is needed, echoing New Zealand's electricity debate as well."

Nick Sharpe, director of communications and strategy at Scottish Renewables, said the current electricity network is "not fit for purpose".

He added: "Groups and individuals who object to the construction of power lines, pylons and substations largely do so because they do not like the way they look.

"By the end of this year, there will be just over 70 months left to achieve our targets of 11 gigawatts (GW) offshore and 12 GW onshore wind.

"To ensure we maximise the enormous socioeconomic benefits this will bring to local communities, we will need a grid fit for the 21st century."

Hydro One CEO's $4.5M salary won't be reduced to help cut electricity costs

Hydro One CEO Salary shapes debate on Ontario electricity costs, executive compensation, sunshine list transparency, and public disclosure rules, as officials argue pay is not driving planned hydro rate cuts for consumers.

 

Key Points

Hydro One CEO pay disclosed in public filings, central to debates on Ontario electricity rates and transparency.

✅ 2016 compensation: $4.5M (salary + bonuses)

✅ Excluded from Ontario's sunshine list after privatization

✅ Government says pay won't affect planned hydro rate cuts

 

The $4.5 million in pay received by Hydro One's CEO is not a factor in the government's plan to cut electricity costs for consumers, an Ontario cabinet minister said Thursday amid opposition concerns about the executive's compensation and wider sector pressures such as Manitoba Hydro's rising debt in other provinces.

Treasury Board President Liz Sandals made her comments on the eve of the release of the province's so-called sunshine list.

The annual disclosure of public-sector salaries over $100,000 will be released Friday, but Hydro One salaries such as that of company boss Mayo Schmidt won't be on it.Though the government still owns most of Hydro One — 30 per cent has been sold — the company is required to follow the financial disclosure rules of publicly traded companies, which means disclosing the salaries of its CEO, CFO and next three highest-paid executives, and financial results such as a Q2 profit decline in filings.

New filings show that Schmidt was paid $4.5 million in 2016 — an $850,000 salary plus bonuses — and those top five executives were paid a total of about $11.7 million. 

"Clearly that's a very large amount," said Sandals. Sandals wouldn't say whether or not she thought the pay was appropriate at a time when the government is trying to reduce system costs and cut people's hydro bills.

Mayo Schmidt, President & CEO of Hydro One Limited and Hydro One Inc. (Hydro One )

But she suggested the CEO's salary was not a factor in efforts to bring down hydro prices, even as Hydro One shares fell after a leadership shakeup in a later period. "The CEO salary is not part of the equation of will 'we be able to make the cut,"' she said. "Regardless of what those salaries are, we will make a 25-per-cent-off cut." The cut coming this summer is actually an average of 17 per cent -- the 25-per-cent figure factors in an earlier eight-per-cent rebate.

NDP Leader Andrea Horwath, who has proposed to make hydro public again in Ontario, said the executive salaries are relevant to cutting hydro costs.

"All of this is cost of operating the electricity system, it's part of the operating of Hydro One and so of course those increased salaries are going to impact the cost of our electricity," she said.

Schmidt was appointed Aug. 31, 2015, and in the last four months of that year earned $1.3 million, but the former CEO was paid $745,000 in 2014. About 3,800 workers were paid over $100,000 that year, none of whom will be on the sunshine list this year.

Progressive Conservative energy critic Todd Smith has a private member's bill that would put Hydro One salaries back on the list, amid investor concerns about Hydro One that cite too many unknowns.

"The Wynne Liberals don't want the people of Ontario to know that their rates have helped create a new millionaire's club at Hydro One," Smith said. "Hydro One is still under the majority ownership of the public, but Premier Kathleen Wynne has removed these salaries from the public's watchful eye."

The previous sunshine list showed 115,431 people were earning more than $100,000 — an increase of nearly 4,000 people despite the fact 3,774 Hydro One workers were not on the list for the first time.

Tom Mitchell, the former CEO at Ontario Power Generation who resigned last summer, topped the 2015 list at $1.59 million.

The Great Debate About Bitcoin's Huge Appetite For Electricity Determining Its Future

Bitcoin Energy Debate examines electricity usage, mining costs, environmental impact, and blockchain efficiency, weighing renewable power, carbon footprint, scalability, and transaction throughput to clarify stakeholder claims from Tesla, Square, academics, and policymakers.

 

Key Points

Debate on Bitcoin mining's power use, environmental impact, efficiency, and scalability versus alternative blockchains.

✅ Compares energy intensity with transaction throughput and system outputs.

✅ Weighs renewables, stranded power, and carbon footprint in mining.

✅ Assesses PoS blockchains, stablecoins, and scalability tradeoffs.

 

There is a great debate underway about the electricity required to process Bitcoin transactions. The debate is significant, the stakes are high, the views are diverse, and there are smart people on both sides. Bitcoin generates a lot of emotion, thereby producing too much heat and not enough light. In this post, I explain the importance of identifying the key issues in the debate, and of understanding the nature and extent of disagreement about how much electrical energy Bitcoin consumes.

Consider the background against which the debate is taking place. Because of its unstable price, Bitcoin cannot serve as a global mainstream medium of exchange. The instability is apparent. On January 1, 2021, Bitcoin’s dollar price was just over $29,000. Its price rose above $63,000 in mid-April, and then fell below $35,000, where it has traded recently. Now the financial media is asking whether we are about to experience another “cyber winter” as the prices of cryptocurrencies continue their dramatic declines.

Bitcoin is a high sentiment beta asset, and unless that changes, Bitcoin cannot serve as a global mainstream medium of exchange. Being a high sentiment beta asset means that Bitcoin’s market price is driven much more by investor psychology than by underlying fundamentals.

As a general matter, high sentiment beta assets are difficult to value and difficult to arbitrage. Bitcoin qualifies in this regard. As a general matter, there is great disagreement among investors about the fair values of high sentiment beta assets. Bitcoin qualifies in this regard.

One major disagreement about Bitcoin involves the very high demand for electrical power associated with Bitcoin transaction processing, an issue that came to light several years ago. In recent months, the issue has surfaced again, in a drama featuring disagreement between two prominent industry leaders, Elon Musk (from Tesla and SpaceX) and Jack Dorsey (from Square).

On one side of the argument, Musk contends that Bitcoin’s great need for electrical power is detrimental to the environment, especially amid disruptions in U.S. coal and nuclear power that increase supply strain.  On the other side, Dorsey argues that Bitcoin’s electricity profile is a benefit to the environment, in part because it provides a reliable customer base for clean electric power. This might make sense, in the absence of other motives for generating clean power; however, it seems to me that there has been a surge in investment in alternative technologies for producing electricity that has nothing to do with cryptocurrency. So I am not sure that the argument is especially strong, but will leave it there. In any event, this is a demand side argument.

A supply side argument favoring Bitcoin is that the processing of Bitcoin transactions, known as “Bitcoin mining,” already uses clean electrical power, power which has already been produced, as in hydroelectric plants at night, but not otherwise consumed in an era of flat electricity demand across mature markets.

Both Musk and Dorsey are serious Bitcoin investors. Earlier this year, Tesla purchased $1.5 billion of Bitcoin, agreed to accept Bitcoin as payment for automobile sales, and then reversed itself. This reversal appears to have pricked an expanding Bitcoin bubble. Square is a digital transaction processing firm, and Bitcoin is part of its long-term strategy.

Consider two big questions at the heart of the digital revolution in finance. First, to what degree will blockchain replace conventional transaction technologies? Second, to what degree will competing blockchain based digital assets, which are more efficient than Bitcoin, overcome Bitcoin’s first mover advantage as the first cryptocurrency?

To gain some insight about possible answers to these questions, and the nature of the issues related to the disagreement between Dorsey and Musk, I emailed a series of academics and/or authors who have expertise in blockchain technology.

David Yermack, a financial economist at New York University, has written and lectured extensively on blockchains. In 2019, Yermack wrote the following: “While Bitcoin and successor cryptocurrencies have grown remarkably, data indicates that many of their users have not tried to participate in the mainstream financial system. Instead they have deliberately avoided it in order to transact in black markets for drugs and other contraband … or evade capital controls in countries such as China.” In this regard, cyber-criminals demanding ransom for locking up their targets information systems often require payment in Bitcoin. Recent examples of cyber-criminal activity are not difficult to find, such as incidents involving Kaseya and Colonial Pipeline.

David Yermack continues: “However, the potential benefits of blockchain for improving data security and solving moral hazard problems throughout the financial system have become widely apparent as cryptocurrencies have grown.” In his recent correspondence with me, he argues that the electrical power issue associated with Bitcoin “mining,” is relatively minor because Bitcoin miners are incentivized to seek out cheap electric power, and patterns shifted as COVID-19 changed U.S. electricity consumption across sectors.

Thomas Philippon, also a financial economist at NYU, has done important work characterizing the impact of technology on the resource requirements of the financial sector. He has argued that historically, the financial sector has comprised about 6-to-7% of the economy on average, with variability over time. Unit costs, as a percentage of assets, have consistently been about 2%, even with technological advances. In respect to Bitcoin, he writes in his correspondence with me that Bitcoin is too energy inefficient to generate net positive social benefits, and that energy crisis pressures on U.S. electricity and fuels complicate the picture, but acknowledges that over time positive benefits might be possible.

Emin Gün Sirer is a computer scientist at Cornell University, whose venture AVA Labs has been developing alternative blockchain technology for the financial sector. In his correspondence with me, he writes that he rejects the argument that Bitcoin will spur investment in renewable energy relative to other stimuli. He also questions the social value of maintaining a fairly centralized ledger largely created by miners that had been in China and are now migrating to other locations such as El Salvador.

Bob Seeman is an engineer, lawyer, and businessman, who has written a book entitled Bitcoin: The Mother of All Scams. In his correspondence with me, he writes that his professional experience with Bitcoin led him to conclude that Bitcoin is nothing more than unlicensed gambling, a point he makes in his book.

David Gautschi is an academic at Fordham University with expertise in global energy. I asked him about studies that compare Bitcoin’s use of energy with that of the U.S. financial sector. In correspondence with me, he cautioned that the issues are complex, and noted that online technology generally consumes a lot of power, with electricity demand during COVID-19 highlighting shifting load profiles.

My question to David Gautschi was prompted by a study undertaken by the cryptocurrency firm Galaxy Digital. This study found that the financial sector together with the gold industry consumes twice as much electrical power as Bitcoin transaction processing. The claim by Galaxy is that Bitcoin’s electrical power needs are “at least two times lower than the total energy consumed by the banking system as well as the gold industry on an annual basis.”

Galaxy’s analysis is detailed and bottom up based. In order to assess the plausibility of its claims, I did a rough top down analysis whose results were roughly consistent with the claims in the Galaxy study. For sake of disclosure, I placed the heuristic calculations I ran in a footnote.1 If we accept the Galaxy numbers, there remains the question of understanding the outputs produced by the electrical consumption associated with both Bitcoin mining and U.S. banks’ production of financial services. I did not see that the Galaxy study addresses the output issue, and it is important.

Consider some quick statistics which relate to the issue of outputs. The total market for global financial services was about $20 trillion in 2020. The number of Bitcoin transactions processed per day was about 330,000 in December 2020, and about 400,000 in January 2021. The corresponding number for Bitcoin’s digital rival Ethereum during this time was about 1.1 million transactions per day. In contrast, the global number of credit card transactions per day in 2018 was about 1 billion.2

These numbers tell us that Bitcoin transactions comprise a small share, on the order of 0.04%, of global transactions, but use something like a third of the electricity needed for these transactions. That said, the associated costs of processing Bitcoin transactions relate to tying blocks of transactions together in a blockchain, not to the number of transactions. Nevertheless, even if the financial sector does indeed consume twice as much electrical power as Bitcoin, the disparity between Bitcoin and traditional financial technology is striking, and the experience of Texas grid reliability underscores system constraints when it comes to output relative to input.  This, I suggest, weakens the argument that Bitcoin’s electricity demand profile is inconsequential because Bitcoin mining uses slack electricity.

A big question is how much electrical power Bitcoin mining would require, if Bitcoin were to capture a major share of the transactions involved in world commerce. Certainly much more than it does today; but how much more?

Given that Bitcoin is a high sentiment beta asset, there will be a lot of disagreement about the answers to these two questions. Eventually we might get answers.

At the same time, a high sentiment beta asset is ill suited to being a medium of exchange and a store of value. This is why stablecoins have emerged, such as Diem, Tether, USD Coin, and Dai. Increased use of these stable alternatives might prevent Bitcoin from ever achieving a major share of the transactions involved in world commerce.

We shall see what the future brings. Certainly El Salvador’s recent decision to make Bitcoin its legal tender, and to become a leader in Bitcoin mining, is something to watch carefully. Just keep in mind that there is significant downside to experiencing foreign exchange rate volatility. This is why global financial institutions such as the World Bank and IMF do not support El Salvador’s decision; and as I keep saying, Bitcoin is a very high sentiment beta asset.

In the past I suggested that Bitcoin bubble would burst when Bitcoin investors conclude that its associated processing is too energy inefficient. Of course, many Bitcoin investors are passionate devotees, who are vulnerable to the psychological bias known as motivated reasoning. Motivated reasoning-based sentiment, featuring denial,3 can keep a bubble from bursting, or generate a series of bubbles, a pattern we can see from Bitcoin’s history.

I find the argument that Bitcoin is necessary to provide the right incentives for the development of clean alternatives for generating electricity to be interesting, but less than compelling. Are there no other incentives, such as evolving utility trends, or more efficient blockchain technologies? Bitcoin does have a first mover advantage relative to other cryptocurrencies. I just think we need to be concerned about getting locked into an technologically inferior solution because of switching costs.

There is an argument to made that decisions, such as how to use electric power, are made in markets with self-interested agents properly evaluating the tradeoffs. That said, think about why most of the world adopted the Windows operating system in the 1980s over the superior Mac operating system offered by Apple. Yes, we left it to markets to determine the outcome. People did make choices; and it took years for Windows to catch up with the Mac’s operating system.

My experience as a behavioral economist has taught me that the world is far from perfect, to expect to be surprised, and to expect people to make mistakes. We shall see what happens with Bitcoin going forward.

As things stand now, Bitcoin is well suited as an asset for fulfilling some people’s urge to engage in high stakes gambling. Indeed, many people have a strong need to engage in gambling. Last year, per capita expenditure on lottery tickets in Massachusetts was the highest in the U.S. at over $930.

High sentiment beta assets offer lottery-like payoffs. While Bitcoin certainly does a good job of that, it cannot simultaneously serve as an effective medium of exchange and reliable store of value, even setting aside the issue at the heart of the electricity debate.
