Bruce Power and the Ontario Power Authority (OPA) have amended their existing Bruce A agreement to allow for the complete refurbishment of Unit 4.

Bruce Power will now replace all 480 fuel channels in Unit 4, extending its operational life until 2036. Under the original 2005 agreement, Bruce Power intended to install new steam generators in all four Bruce A units and fuel channels in Units 1, 2 and 3. Without new fuel channels, Unit 4 was only expected to run until 2017.

Under the revised plan, Bruce Power expects to invest an additional $1 billion, resulting in a total investment in the restart and refurbishment program of approximately $5.25 billion.

"Expanding our project will allow us to conduct the complete refurbishment of Units 3 and 4 in a similar manner to how we are conducting the restart of Units 1 and 2," said Duncan Hawthorne, Bruce Power's President and Chief Executive Officer. "We are well into one of North America's most complex engineering projects and we remain on time and on budget. Our team of contractors is well established at Bruce A and their processes are working well."

Bruce Power expects to complete the work on Units 3 and 4 by 2013. Under the revised agreement, the OPA can elect for a three unit restart program if it expects there will be insufficient transmission to accommodate all eight Bruce Power units by mid 2013. This election expires on April 1, 2008. In April, Hydro One announced plans to upgrade the transmission line between Bruce Power and Milton, Ont. and expects the new line to be in service by 2012.

Meanwhile, work to restart Units 1 and 2 continues and is expected to deliver an additional 1,500 megawatts to the Ontario power grid by late 2009 or early 2010.

Is Ontario's Power Cost-Effective?

Ontario Nuclear Power Costs highlight LCOE, capex, refurbishment outlays, and waste management, compared with renewables, grid reliability, and emissions targets, informing Australia and Peter Dutton on feasibility, timelines, and electricity prices.

 

Key Points

They include high capex and LCOE from refurbishments and waste, offset by reliable, low-emission baseload.

✅ Refurbishment and maintenance drive lifecycle and LCOE variability.

✅ High capex and long timelines affect consumer electricity prices.

✅ Low emissions, but waste and safety compliance add costs.

 

Australian opposition leader Peter Dutton recently lauded Canada’s use of nuclear power as a model for Australia’s energy future. His praise comes as part of a broader push to incorporate nuclear energy into Australia’s energy strategy, which he argues could help address the country's energy needs and climate goals. However, the question arises: Is Ontario’s experience with nuclear power as cost-effective as Dutton suggests?

Dutton’s endorsement of Canada’s nuclear power strategy highlights a belief that nuclear energy could provide a stable, low-emission alternative to fossil fuels. He has pointed to Ontario’s substantial reliance on nuclear power, and the province’s exploration of new large-scale nuclear projects, as an example of how such an energy mix might benefit Australia. The province’s energy grid, which integrates a significant amount of nuclear power, is often cited as evidence that nuclear energy can be a viable component of a diversified energy portfolio.

The appeal of nuclear power lies in its ability to generate large amounts of electricity with minimal greenhouse gas emissions. This characteristic aligns with Australia’s climate goals, which emphasize reducing carbon emissions to combat climate change. Dutton’s advocacy for nuclear energy is based on the premise that it can offer a reliable and low-emission option compared to the fluctuating availability of renewable sources like wind and solar.

However, while Dutton’s enthusiasm for the Canadian model reflects its perceived successes, including recent concerns about Ontario’s grid getting dirtier amid supply changes, a closer look at Ontario’s nuclear energy costs raises questions about the financial feasibility of adopting a similar strategy in Australia. Despite the benefits of low emissions, the economic aspects of nuclear power remain complex and multifaceted.

In Ontario, the cost of nuclear power has been a topic of considerable debate. While the province benefits from a stable supply of electricity due to its nuclear plants, studies warn of a growing electricity supply gap in coming years. Ontario’s experience reveals that nuclear power involves significant capital expenditures, including the costs of building reactors, maintaining infrastructure, and ensuring safety standards. These expenses can be substantial and often translate into higher electricity prices for consumers.

The cost of maintaining existing nuclear reactors in Ontario has been a particular concern. Many of these reactors are aging and require costly upgrades and maintenance to continue operating safely and efficiently. These expenses can add to the overall cost of nuclear power, impacting the affordability of electricity for consumers.

Moreover, the development of new nuclear projects, as seen with Bruce C project exploration in Ontario, involves lengthy and expensive construction processes. Building new reactors can take over a decade and requires significant investment. The high initial costs associated with these projects can be a barrier to their economic viability, especially when compared to the rapidly decreasing costs of renewable energy technologies.

In contrast, the cost of renewable energy has been falling steadily, even as debates over nuclear power’s trajectory in Europe continue, making it a more attractive option for many jurisdictions. Solar and wind power, while variable and dependent on weather conditions, have seen dramatic reductions in installation and operational costs. These lower costs can make renewables more competitive compared to nuclear energy, particularly when considering the long-term financial implications.

Dutton’s praise for Ontario’s nuclear power model also overlooks some of the environmental and logistical challenges associated with nuclear energy. While nuclear power generates low emissions during operation, it produces radioactive waste that requires long-term storage solutions. The management of nuclear waste poses significant environmental and safety concerns, as well as additional costs for safe storage and disposal.

Additionally, the potential risks associated with nuclear power, including the possibility of accidents, contribute to the complexity of its adoption. The safety and environmental regulations surrounding nuclear energy are stringent and require continuous oversight, adding to the overall cost of maintaining nuclear facilities.

As Australia contemplates integrating nuclear power into its energy mix, it is crucial to weigh these financial and environmental considerations. While the Canadian model provides valuable insights, the unique context of Australia’s energy landscape, including its existing infrastructure, energy needs, and the costs of scrapping coal-fired electricity in comparable jurisdictions, must be taken into account.

In summary, while Peter Dutton’s endorsement of Canada’s nuclear power model reflects a belief in its potential benefits for Australia’s energy strategy, the cost-effectiveness of Ontario’s nuclear power experience is more nuanced than it may appear. The high capital and maintenance costs associated with nuclear energy, combined with the challenges of managing radioactive waste and ensuring safety, present significant considerations. As Australia evaluates its energy future, a comprehensive analysis of both the benefits and drawbacks of nuclear power will be essential to making informed decisions about its role in the country’s energy strategy.

Magnitude 5 quake strikes near Iran nuclear plant

Iran Bushehr Earthquake rattles southern province near the Bushehr nuclear power plant, USGS reports M5.1 at 38 km depth; seismic activity along major fault lines raises safety, damage, and monitoring concerns.

 

Key Points

A magnitude 5.1 quake near Bushehr nuclear plant at 38 km depth, with no damage reported, per USGS.

✅ USGS lists magnitude 5.1 at 38 km depth

✅ Near Bushehr nuclear power plant; built for stronger quakes

✅ Iran lies on major fault lines; quake risk is frequent

 

A magnitude 5 earthquake struck southern Iran early Friday near the Islamic Republic's only nuclear power plant. There were no immediate reports of damage or injuries as Iran continues combined-cycle conversions across its power sector.

The quake hit Iran's Bushehr province at 5:23 a.m., according to the U.S. Geological Survey. It put the magnitude at 5.1 and the depth of the earthquake at 38 kilometres (24 miles), in a province tied to efforts to transmit electricity to Europe in coming years.

Iranian state media did not immediately report on the quake. However, the Bushehr nuclear power plant was designed to withstand much stronger earthquakes, a notable consideration as Iraq plans nuclear power plants to address shortages.

A magnitude 5 earthquake can cause considerable damage, including power disruptions that have seen blackouts spark protests in some Iranian cities.

Iran sits on major fault lines and is prone to near-daily earthquakes, yet it remains a key player in regional power, with Iran-Iraq energy cooperation ongoing. In 2003, a 6.6-magnitude quake flattened the historic city of Bam, killing 26,000 people, and today Iran supplies 40% of Iraq's electricity through cross-border power deals. Bam is near the Bushehr nuclear plant, which wasn’t damaged at that time, while more recently Iran finalized deals to rehabilitate Iraq's power grid to improve resilience.

Edmonton's 1st electric bus hits city streets

Edmonton Electric Buses usher in zero-emission public transit with Proterra battery-electric vehicles, 350 km range, quiet rides, winter-ready performance, and overhead depot chargers, as ETS rolls out Canada's largest electric fleet across city routes.

 

Key Points

Battery-electric ETS vehicles from Proterra deliver zero-emission service, 350 km range, and winter-capable operation.

✅ Up to 350 km per charge; overhead depot fast chargers

✅ Quiet, smooth rides; zero tailpipe emissions

✅ Winter-tested performance across ETS routes

 

Your next trip on Edmonton transit could be a historical one as the city’s first battery-electric bus is now on city streets, marking a milestone for Edmonton Transit Service, and neighboring St. Albert has also introduced electric buses as part of regional goals.

“Transit has been around since 1908 in Edmonton. We had some really small buses, we had some trolley buses several years later. It’s a special day in history today,” Ryan Birch, acting director of transit operations, said. “It’s a fresh experience… quiet, smooth riding. It’s going to be absolutely wonderful.”

In a news release, Mayor Don Iveson called it the largest purchase of electric buses in Canadian history, while North America's largest electric bus fleet operates in Toronto today, and Metro Vancouver has buses on the road as well this year.

“Electric buses are a major component of the future of public transit in our city and across Canada.”

As of Tuesday, 21 of the 40 electric buses had arrived in the city, and the Toronto Transit Commission has introduced battery-electric buses in Toronto as well this year.

“We’re going to start rolling these out with four or five buses per day until we’ve got all the buses in stock rolled out. On Wednesday we will have three or four buses out,” Birch said.

The remaining 19 are scheduled to arrive in the fall.

The City of Edmonton ordered the battery-electric buses from Proterra, an electric bus supplier, while Montreal's STM has begun rolling out electric buses of its own recently.

The fleet can travel up to 350 kilometres on a single charge and the batteries work in all weather conditions, including Edmonton’s harsh winters, and electric school buses in B.C. have also taken to the roads in cold climates recently.

In 2015, ETS winter tested a few electric buses to see if the technology would be suitable for the city’s climate and geography amid barriers to wider adoption that many agencies consider.

“These buses are designed to handle most of our routes,” Birch said. “We are confident they will be able to stand up to what we expect of them.”

ETS is the first transit agency in North America to have overhead chargers installed inside transit facilities, which helps to save floor space.

Ex-SpaceX engineers in race to build first commercial electric speedboat

Arc One Electric Speedboat delivers zero-emission performance, quiet operation, and reduced maintenance, leveraging battery propulsion, aerospace engineering, and venture-backed innovation to cut noise pollution, fuel costs, and water contamination in high-performance marine recreation.

 

Key Points

Arc One Electric Speedboat is a battery-powered, zero-emission craft offering quiet, high-performance marine cruising.

✅ 475 hp, 24 ft hull, about 40 mph top speed

✅ Cuts noise, fumes, and water contamination vs gas boats

✅ Backed by Andreessen Horowitz; ex-SpaceX engineers

 

A team of former SpaceX rocket engineers have joined the race to build the first commercial electric speedboat.

The Arc Boat company announced it had raised $4.25m (£3m) in seed funding to start work on a 24ft 475-horsepower craft that will cost about $300,000.

The LA-based company, which is backed by venture capital firm Andreessen Horowitz (an early backer of Facebook and Airbnb), said the first model of the Arc One boat would be available for sale by the end of the year.

Mitch Lee, Arc’s chief executive, said he wanted to build electric boats because of the impact conventional petrol- or diesel-powered boats have on the environment.

“They not only get just two miles to the gallon, they also pump a lot of those fumes into the water,” Lee said. “In addition, there is the huge noise pollution factor [of conventional boats] and that is awful for the marine life. With gas-powered boats it’s not just carbon emissions into the air, it’s also polluting the water and causing noise pollution. Electric boats, like electric ships clearing the air on the B.C. coast, eliminate all that.”

Lee said electric vessels would also reduce the hassle of boat ownership. “I love being out on the water, being on a boat is so much fun, but owning a boat is so awful,” he said. “I have always believed that electric boats make sense. They will be quicker, quieter and way cheaper and easier to operate and maintain, with access options like an electric boat club in Seattle lowering barriers for newcomers.”

While the first models will be very expensive, Lee said the cost was mostly in developing the technology and cheaper versions would be available in the future, mirroring advances in electric aviation seen across the industry. “It is very much the Tesla approach – we are starting up market and using that income to finance research and development and work our way down market,” he said.

Lee said the technology could be applied to larger craft, and even ferries could run on electricity in the future, as projects for battery-electric high-speed ferries begin to scale.

“We started in February with no team, no money and no warehouse,” he said. “By December we are going to be selling the Arc One, and we are hiring aggressively because we want to accelerate the adoption of electric boats across a whole range of craft, including an electric-ready ferry on Kootenay Lake.”

Lee founded the company with fellow mechanical engineer Ryan Cook. Cook, the company’s chief technology officer, was previously the lead mechanical engineer at Elon Musk’s space exploration company SpaceX where he worked on the Falcon 9 rocket, the world’s first orbital class reusable rocket. In parallel, Harbour Air's electric aircraft highlights cross-sector electrification. Apart from Lee, all of Arc’s employees have some experience working at SpaceX.

The Arc boat, which would have a top speed of 40 mph, joins a number of startups rushing to make the first large-scale production of electric-powered speedboats, while a Vancouver seaplane airline demonstrates complementary progress with a prototype electric aircraft. The Monaco Yacht Club this month held a competition for electric boat prototypes to “instigate a new vision and promote all positive approaches to bring yachting into line” with global carbon dioxide emission reduction targets. Sweden’s Candela C-7 hydrofoil boat was crowned the fastest electric vessel.

Electricity complaints filed by Texans reach three-year high, report says

Texas Electricity Complaints surged to a three-year high, highlighting Public Utility Commission data on billing disputes, meter problems, and service issues in the competitive retail electricity market and consumer protection process.

 

Key Points

Consumer filings to Texas PUC about billing, service, and meters, with 2018 reaching a three-year high.

✅ 5,371 complaints/inquiries in FY2018; 43.8% involved billing disputes.

✅ Service issues 15.8% and meters 12.6%; PUC publishes complaint stats.

✅ Advocates urge monitoring to keep deregulated retail market healthy.

 

The number of electricity service-related complaints and inquiries filed with the state’s Public Utility Commission reached a three-year high this past fiscal year, an advocacy group said Tuesday.

According to the Texas Coalition for Affordable Power, a nonprofit that advocates for low electricity prices, Texans filed 5,371 complaints or inquiries with the commission between September 2017 and August of this year. That’s up from the 4,175 complaints or inquiries filed during the same period in 2017 and the 4,835 filed in 2016. The complaints and inquiries included concerns with billing, meters and service.

“This stark uptick in complaints is disappointing — especially after several years of generally improving numbers,” Jay Doegey, the coalition's executive director, said in a written statement. “In percentage terms, the year-to-year rise in complaints is the greatest in a decade. Clearly, many Texans remain frustrated with aspects of their electric service.”

The utility commission did not immediately respond to a request for comment.

While complaints and inquiries increased in 2018, the number of complaints and inquiries has generally decreased since 2009, when Texans filed 15,956 with the commission. That could be because there have been lower residential electricity prices and because Texans have become more familiar with the state’s competitive retail electricity system over the last decade, the coalition's report said.

And complaints from 2018 are well below 2003 levels, when the number of complaints and inquiries soared to more than 17,000, a year after Texas deregulated most of its electricity market structure at the time.

But Jake Dyer, a policy analyst at the coalition, said his group is closely watching the uptick in complaints this year as the Texas power grid faces recurring strains.

“We are invested in making sure the competition works,” Dyer said. “When you see an uptick like this, you should watch very closely to make sure the market remains healthy and to make sure there is not something else going on.”

However, Dyer said that it is too early to know what that something else that is going on might be.

According to the report, concerns about billing made up most of the complaints and inquiries filed this year at 43.8 percent. That’s up from 42.5 percent in fiscal year 2017. Concerns about the provision of electrical service and about electrical meters also ranked high, constituting 15.8 percent and 12.6 percent of the complaints and inquiries, respectively.

The Public Utility Commission publishes customer complaint statistics on its website. The Texas Coalition for Affordable Power takes into account both complaints and inquiries filed with the commission for its report in order “to gauge general consumer sentiment and to maintain a uniform methodology across the study period.”

Texans can file an official complaint with the the commission's Customer Protection Division. Under the complaint process, the complaint is sent to the electric company, which has 21 days to respond.

Some providers outside the competitive market, such as electric cooperatives, drew praise for performance during the 2021 winter storm.

Following the 2021 winter storm, Texas lawmakers proposed an electricity market bailout to stabilize costs and reliability.

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.

Central banks warns of bubble on bitcoins as it skyrockets
As bitcoins skyrocket to more than $12 000 for one BTC, many central banks as ECB or US Federal ... [+] NURPHOTO VIA GETTY IMAGES
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

Bitcoin Value Falls
LONDON, ENGLAND - NOVEMBER 20: A visual representation of the cryptocurrencies Bitcoin and Ethereum ... [+] GETTY IMAGES
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.
