Bitcoin Energy Consumption drives debate on blockchain mining, proof-of-work, carbon footprint, and emissions, with CCAF estimates in terawatt hours highlighting electricity demand, fossil fuel reliance, and sustainability concerns for data centers and cryptocurrency networks.

Key Points

Electricity used by Bitcoin proof-of-work mining, often fossil-fueled, estimated by CCAF in terawatt hours.

✅ CCAF: 40-445 TWh, central estimate ~130 TWh

✅ ~66% of mining electricity sourced from fossil fuels

✅ Proof-of-work increases hash rate, energy, and emissions

The University of Cambridge Centre for Alternative Finance (CCAF) studies the burgeoning business of cryptocurrencies.

It calculates that Bitcoin's total energy consumption is somewhere between 40 and 445 annualised terawatt hours (TWh), with a central estimate of about 130 terawatt hours.

The UK's electricity consumption is a little over 300 TWh a year, while Argentina uses around the same amount of power as the CCAF's best guess for Bitcoin, as countries like New Zealand's electricity future are debated to balance demand.

And the electricity the Bitcoin miners use overwhelmingly comes from polluting sources, with the U.S. grid not 100% renewable underscoring broader energy mix challenges worldwide.

The CCAF team surveys the people who manage the Bitcoin network around the world on their energy use and found that about two-thirds of it is from fossil fuels, and some regions are weighing curbs like Russia's proposed mining ban amid electricity deficits.

Huge computing power - and therefore energy use - is built into the way the blockchain technology that underpins the cryptocurrency has been designed.

It relies on a vast decentralised network of computers.

These are the so-called Bitcoin "miners" who enable new Bitcoins to be created, but also independently verify and record every transaction made in the currency.

In fact, the Bitcoins are the reward miners get for maintaining this record accurately.

It works like a lottery that runs every 10 minutes, explains Gina Pieters, an economics professor at the University of Chicago and a research fellow with the CCAF team.

Data processing centres around the world, including hotspots such as Iceland's mining strain, race to compile and submit this record of transactions in a way that is acceptable to the system.

They also have to guess a random number.

The first to submit the record and the correct number wins the prize - this becomes the next block in the blockchain.

Estimates for bitcoin's electricity consumption
At the moment, they are rewarded with six-and-a-quarter Bitcoins, valued at about $50,000 each.

As soon as one lottery is over, a new number is generated, and the whole process starts again.

The higher the price, says Prof Pieters, the more miners want to get into the game, and utilities like BC Hydro suspending new crypto connections highlight grid pressures.

"They want to get that revenue," she tells me, "and that's what's going to encourage them to introduce more and more powerful machines in order to guess this random number, and therefore you will see an increase in energy consumption," she says.

And there is another factor that drives Bitcoin's increasing energy consumption.

The software ensures it always takes 10 minutes for the puzzle to be solved, so if the number of miners is increasing, the puzzle gets harder and the more computing power needs to be thrown at it.

Bitcoin is therefore actually designed to encourage increased computing effort.

The idea is that the more computers that compete to maintain the blockchain, the safer it becomes, because anyone who might want to try and undermine the currency must control and operate at least as much computing power as the rest of the miners put together.

What this means is that, as Bitcoin gets more valuable, the computing effort expended on creating and maintaining it - and therefore the energy consumed - inevitably increases.

We can track how much effort miners are making to create the currency.

They are currently reckoned to be making 160 quintillion calculations every second - that's 160,000,000,000,000,000,000, in case you were wondering.

And this vast computational effort is the cryptocurrency's Achilles heel, says Alex de Vries, the founder of the Digiconomist website and an expert on Bitcoin.

All the millions of trillions of calculations it takes to keep the system running aren't really doing any useful work.

"They're computations that serve no other purpose," says de Vries, "they're just immediately discarded again. Right now we're using a whole lot of energy to produce those calculations, but also the majority of that is sourced from fossil energy, and clean energy's 'dirty secret' complicates substitution."

The vast effort it requires also makes Bitcoin inherently difficult to scale, he argues.

"If Bitcoin were to be adopted as a global reserve currency," he speculates, "the Bitcoin price will probably be in the millions, and those miners will have more money than the entire [US] Federal budget to spend on electricity."

"We'd have to double our global energy production," he says with a laugh, even as some argue cheap abundant electricity is getting closer to reality today. "For Bitcoin."

He says it also limits the number of transactions the system can process to about five per second.

This doesn't make for a useful currency, he argues.

And that view is echoed by many eminent figures in finance and economics.

The two essential features of a successful currency are that it is an effective form of exchange and a stable store of value, says Ken Rogoff, a professor of economics at Harvard University in Cambridge, Massachusetts, and a former chief economist at the International Monetary Fund (IMF).

He says Bitcoin is neither.

"The fact is, it's not really used much in the legal economy now. Yes, one rich person sells it to another, but that's not a final use. And without that it really doesn't have a long-term future."

What he is saying is that Bitcoin exists almost exclusively as a vehicle for speculation.

So, I want to know: is the bubble about to burst?

"That's my guess," says Prof Rogoff and pauses.

"But I really couldn't tell you when."

Hydro One-Avista acquisition sparks Idaho regulatory scrutiny over foreign ownership, utility merger impacts, rate credits, and public interest, as FERC and FCC approvals advance and consumers question governance, service reliability, and long-term rate stability.

Key Points

A cross-border utility merger proposal with Idaho oversight, weighing foreign ownership, rates, and reliability.

✅ Idaho PUC review centers on public interest and rate impacts.

✅ FERC and FCC approvals granted; state decisions pending.

✅ Avista to retain name and Spokane HQ post-transaction.

“Please don’t sell us to Canada.” That refrain, or versions of it, is on full display at the Idaho Public Utilities Commission, which admittedly isn’t everyone’s go-to entertainment site. But it is vitally important for this reason: the first big test of the expansionist dreams of the politically tempest-tossed Hydro One, facing political risk as it navigates markets, rests with its successful acquisition of Avista Corp., provider of electric generation, transmission and distribution to retail customers spread from Oregon to Washington to Montana and Idaho and up into Alaska.

The proposed deal — announced last summer, but not yet consummated — marks the first time the publicly traded Hydro One has embarked upon the acquisition of a U.S. utility. And if Idahoans spread from Boise to Coeur d’Alene to Hayden are any indication, they are not at all happy with the idea of foreign ownership. Here’s Lisa McCumber, resident of Hayden: “I am stating my objection to this outrageous merger/takeover. Hydro One charges excessive fees to the people it provides for, this is a monopoly beyond even what we are used to. I, in no way, support or as a customer, agree with the merger of this multi-billion-dollar, foreign, company.”

#google#

Or here’s Debra Bentley from Coeur d’Alene: “Fewer things have more control over a nation than its power source. In an age where we are desperately trying to bring American companies back home and ‘Buy American’ is somewhat of a battle cry, how is it even possible that it would or could be allowed for this vital necessity … to be controlled by a foreign entity?”

Or here’s Spencer Hutchings from Sagle: “This is an incredibly bad idea.”

There are legion of similar emails from concerned consumers, and the Maine transmission line debate offers a parallel in public opposition.

The rationale for the deal? Last fall Hydro One CEO Mayo Schmidt testified before the Idaho commission, which regulates all gas, water and electricity providers in the state. “Hydro One is a pure-play transmission and distribution utility located solely within Ontario,” Schmidt told commissioners. “It seeks diversification both in terms of jurisdictions and service areas. The proposed Transaction with Avista achieves both goals by expanding Hydro One into the U.S. Pacific Northwest and expanding its operations to natural gas distribution and electric generation. The proposed Transaction with Avista will deliver the increased scale and benefits that come from being a larger player in the utility industry.”

Translation: now that it is a publicly traded entity, Hydro needs to demonstrate a growth curve to the investment community. The value to you and me? Arguable. This is a transaction framed as a benefit to shareholders, one that won’t cause harm to customers. Premier Kathleen Wynne is feeling the pain of selling off control of an essential asset. In his testimony to the commission, Schmidt noted that the Avista acquisition would take the province’s Hydro ownership to under 45 per cent. (The Electricity Act technically prevents the sale of shares that would take the government’s ownership position below 40 per cent, though acquisitions appear to allow further dilution. )

Stratospheric compensation, bench-marked against other chief executives who enjoy similarly outsized rewards, is part of this game. I have written about Schmidt’s unconscionable compensation before, but that was when he was making a relatively modest $4 million. Relative, that is, to his $6.2 million in 2017 compensation ($3.5 million of that is in the form of share based awards).

Should the acquisition of Avista be approved, amendments to the CIC, or change in control agreements, for certain named Avista executive officers will allow them to voluntarily terminate their employment without “good reason.” That includes Scott Morris, the company’s CEO, who will exit with severance of $6.9 million (U.S.) and additional benefits taking the total to a potential $15.7 million.

Back to the deal: cost savings over time could be achieved, Schmidt continued in his testimony, though he was unable to quantify those. The integration between the two companies, he promised, will be “seamless.” Retail customers in Idaho, Washington and Oregon would benefit from proposed “Rate Credits” equalling an estimated $15.8 million across five years, even as Hydro One seeks to redesign its bills in Ontario. Idahoans would see a one per cent rate decrease through that period.

While Avista would become a wholly owned Hydro subsidiary, it would retain its name, and its headquarters in Spokane, Wash. In the case of Idaho specifically, a proposed settlement in April, subject to final approval by the commission, stipulates agreements on everything from staffing to governance to community contributions.

Will that meet the test? It’s up to the commission to determine whether the proposed transaction will keep a lid on rates and is “consistent with the public interest.” Hydro One is hoping for a decision from regulatory agencies in all the named states by mid-August and a closing date by the end of September, though U.S. regulators can ultimately determine the fate of such deals. The Federal Energy Regulatory Commission granted its approval in January, followed last week by the Federal Communications Commission. Washington and Alaska have reached settlement agreements. These too are pending final state approvals.

The $5.3-billion deal (or $6.7 billion Canadian) is subject to ongoing hearings in Idaho, and elsewhere rate hikes face opposition as hearings begin. Members of the public are encouraged to have their say. The public comment deadline is June 27.

Remote Work Energy Costs are rising as home offices and telecommuting boost electricity bills; utilities, broadband usage, and COVID-19-driven stay-at-home policies affect productivity, consumption patterns, and household budgets across the U.K. and Europe.

Key Points

Remote Work Energy Costs are increased household electricity and utility expenses from telecommuting and home office use.

✅ WFH shifts energy load from offices to households.

✅ Higher device, lighting, and heating/cooling usage drives bills.

✅ Broadband access gaps limit remote work equity.

Household electricity bills are set to soar, with rising residential electricity use tied to the millions of people now working at home to avoid catching the coronavirus.

Running laptops and other home appliances will cost consumers an extra 52 million pounds ($60 million) each week in the U.K., according to a study from Uswitch, a website that helps consumers compare the energy prices that utilities charge.

For each home-bound household, the pain to the pocketbook may be about 195 pounds per year extra, even as some utilities pursue pandemic cost-cutting to manage financial pressures.

The rise in price for households comes even as overall demand is falling rapidly in Europe, with wide swaths of the economy shut down to keep workers from gathering in one place, and the U.S. grid overseer issuing warnings about potential pandemic impacts on operations.

People stuck at home will plug in computers, lights and appliances when they’d normally be at the office, increasing their consumption.

With the Canadian government declaring a state of emergency due to the coronavirus, companies are enabling work-from-home structures to keep business running and help employees follow social distancing guidelines, and some utilities have even considered housing critical staff on site to maintain operations. However, working remotely has been on the rise for a while.

“The coronavirus is going to be a tipping point. We plodded along at about 10% growth a year for the last 10 years, but I foresee that this is going to really accelerate the trend,” Kate Lister, president of Global Workplace Analytics.

Gallup’s State of the Workplace 2017 study found that 43% of employees work remotely with some frequency. Research indicates that in a five-day workweek, working remotely for two to three days is the most productive. That gives the employee two to three days of meetings, collaboration and interaction, with the opportunity to just focus on the work for the other half of the week.

Remote work seems like a logical precaution for many companies that employ people in the digital economy, even as some federal agencies sparked debate with an EPA telework policy during the pandemic. However, not all Americans have access to the internet at home, and many work in industries that require in-person work.

According to the Pew Research Center, roughly three-quarters of American adults have broadband internet service at home. However, the study found that racial minorities, older adults, rural residents and people with lower levels of education and income are less likely to have broadband service at home. In addition, 1 in 5 American adults access the internet only through their smartphone and do not have traditional broadband access. 

Full-time employees are four times more likely to have remote work options than part-time employees. A typical remote worker is college-educated, at least 45 years old and earns an annual salary of $58,000 while working for a company with more than 100 employees, according to Global Workplace Analytics, and in Canada there is growing interest in electricity-sector careers among younger workers. 

New York, California and other states have enacted strict policies for people to remain at home during the coronavirus pandemic, which could change the future of work, and Canadian provinces such as Saskatchewan have documented how the crisis has reshaped local economies across sectors.

“I don’t think we’ll go back to the same way we used to operate,” Jennifer Christie, chief HR officer at Twitter, told CNBC. “I really don’t.”

Western Canada Electric Grid could deliver interprovincial transmission, reliability, peak-load support, reserve sharing, and wind and solar integration, lowering costs versus new generation while respecting AESO markets and Crown utility structures.

Key Points

Interprovincial transmission to share reserves, boost reliability, integrate wind and solar, and cut peak capacity costs.

✅ Cuts reserve margins via diversity of peak loads

✅ Enables wind and solar balancing across provinces

✅ Saves ratepayers vs replacing retiring thermal plants

The 2017 Canadian Free Trade Agreement does not do much to encourage provinces to trade electric energy east and west. Would a western Canada electric grid help electricity consumers in the western provinces? Some Alberta officials feel that their electric utilities are investor owned and they perceive the Crown corporations of BC Hydro, SaskPower and Manitoba Hydro to be subsidized by their provincial governments, so an interprovincial electric energy trade would not be on a level playing field.

Because of the limited trade of electric energy between the western provinces, each utility maintains an excessive reserve of thermal and hydroelectric generation greater than their peak loads, to provide a reliable supply during peak load days as grids are increasingly exposed to harsh weather across Canada. This excess does not include variable wind and solar generation, which within a province can’t be guaranteed to be available when needed most.

This attitude must change. Transmission is cheaper than generation, and coordinated macrogrids can further improve reliability and cut costs. By constructing a substantial grid with low profile and aesthetically designed overhead transmission lines, the excess reserve of thermal and hydroelectric generation above the peak electric load can be reduced in each province over time. Detailed assessments will ensure each province retains its required reliability of electric supply.

As the provinces retire aging thermal and coal-fired generators, they only need to replace them to a much lower level, by just enough to meet their future electric loads and Canada's net-zero grid by 2050 goals. Some of the money not spent in replacing retired generation can be profitably invested in the transmission grid across the four western provinces.

But what about Alberta, which does not want to trade electric energy with the other western provinces? It can carry on as usual within the Alberta Electric System Operator’s (AESO) market and will save money by keeping the installed reserve of thermal and hydroelectric generation to a minimum. When Alberta experiences a peak electric load day and some generators are out of service due to unplanned maintenance, it can obtain the needed power from the interprovincial electric grid. None of the other three western provinces will peak at the same time, because of different weather and time zones, so they will have spare capacity to help Alberta over its peak. The peak load in a province only lasts for a few hours, so Alberta will get by with a little help from its friends if needed.

The grid will have no energy flowing on it for this purpose except to assist a province from time to time when it’s unable to meet its peak load. The grid may only carry load five per cent of the time in a year for this purpose. Under such circumstances, the empty grid can then be used for other profitable markets in electric energy. This includes more effective use of variable wind and solar energy, by enabling a province to better balance such intermittent power as well as allowing increased installation of it in every province. This is a challenge for AESO which the grid would substantially ease.

Natural Resources Canada promoted the “Regional Electricity Co-Operative and Strategic Infrastructure” initiative for completion this year and contracted through AESO, alongside an Atlantic grid study to explore regional improvements. This is a first step, but more is needed to achieve the full benefit of a western grid.

In 1970 a study was undertaken to electrically interconnect Britain with France, which was justified based on the ability to reduce reserve generation in both countries. Initially Britain rejected it, but France was partially supportive. In time, a substantial interconnection was built, and being a profitable venture, they are contemplating increasing the grid connections between them.

For the sake of the western consumers of electricity and to keep electricity rates from rising too quickly, as well as allowing productive expansion of wind and solar energy in places like British Columbia's clean energy shift efforts, an electric grid is essential across western Canada.

Dennis Woodford is president of Electranix Corporation in Winnipeg, which studies electric transmission problems, particularly involving renewable energy generators requiring firm connection to the grid.

India Thermal Power Coal Imports surged 17.6% as CEA-monitored plants offset weaker CIL and SCCL supplies, driven by Saubhagya-led electricity demand, regional power deficits, and varied consumption across Uttar Pradesh, Bihar, Maharashtra, and Gujarat.

Key Points

Fuel volumes imported for Indian thermal plants, tracked by CEA, reflecting shifts in CIL/SCCL supply, demand, and regional power deficits.

✅ Imports up 17.6% as domestic CIL/SCCL deliveries lag targets

✅ Saubhagya-driven demand lifts generation in key beneficiary states

✅ Industrial slowdowns cut usage in Maharashtra, Tamil Nadu, Gujarat

The receipt of imported coal by thermal power plants, where plant load factors have risen, has shot up by 17.6 per cent during April-October. The coal import volumes refer to the power plants monitored by the Central Electricity Authority (CEA), and come amid moves to ration coal supplies as electricity demand surges, a power update report from CARE Ratings showed.

Imports escalated as domestic supplies by Coal India Ltd (CIL) and another state run producer- Singareni Collieries Company Ltd (SCCL) dipped in the period, after earlier shortages that have since eased in later months. Rate of supplies by the two coal companies to the CEA monitored power stations stood at 80.4 per cent, indicating a shortfall of 19.6 per cent against the allocated quantity.

According to the study by CARE Ratings, total coal supplied by CIL and SCCL to the power sector stood at 315.9 million tonnes (mt) during April-October as against 328.5 mt in the comparable period of last fiscal year.

The study noted that growth in power generation during the April-October 2019, with India now the third-largest electricity producer globally, was on account of higher demand from Pradhan Mantri Sahaj Bijli Har Ghar Yojana or Saubhagya Scheme beneficiary states. Providing connection to households in order to achieve 100% per cent electrification has in part helped the sector avert de-growth, as part of efforts to rewire Indian electricity and expand access.

Large states namely Uttar Pradesh, Bihar, Punjab, West Bengal and Rajasthan have recorded over five per cent growth in consumption of power. These states along with Odisha, Madhya Pradesh and Assam accounted for 75 per cent of the beneficiaries under the Saubhagya Scheme (Household Electrification Scheme). The ongoing economic downturn has led to a sharp fall in electricity demand from industrialised states. Maharashtra, which is also the largest power consuming state in India, recorded a decline in consumption of 5.6 per cent.

Other states namely Tamil Nadu, Telangana, Gujarat and Odisha too recorded fall in power consumed, echoing global dips in daily electricity demand seen later during the pandemic. These states house large clusters of mining, automobile, cement and other manufacturing industries, and a decline in these sectors led to fall in demand for power across these states. - The demand-supply gap or power deficit has remained at 0.6 per cent during the April-October 2019. North-East reported 4.8 per cent of power deficit followed by Northern Region at 1.3 per cent. Within Northern Region, Jammu & Kashmir and Uttar Pradesh accounted for 65 per cent and 30 per cent respectively of the regions power supply deficit.

NEIMA advances NRC regulatory modernization, creating a licensing framework for advanced reactors, improving uranium permitting, capping reactor fees, and mandating DOE planning for excess uranium, boosting transparency, accountability, and innovation across the US nuclear sector.

Key Points

NEIMA is a US law modernizing NRC rules and enabling advanced reactor licensing while reforming fees.

✅ Modernizes NRC licensing for advanced reactors

✅ Caps annual reactor fees and boosts transparency

✅ Streamlines uranium permitting; directs DOE plans

Bipartisan legislation modernising US nuclear regulation and supporting the establishment of a licensing framework for next-generation advanced reactors has been signed by US President Donald Trump, whose order boosting U.S. uranium and nuclear energy underscored the administration's focus on the sector.

The Nuclear Energy Innovation and Modernisation Act (NEIMA) became law on 14 January.

As well as directing the Nuclear Regulatory Commission (NRC) to modify the licensing process for commercial advanced nuclear reactor facilities, the bill establishes new transparency and accountability measures to the regulator's budget and fee programmes, and caps fees for existing reactors. It also directs the NRC to look at ways of improving the efficiency of uranium licensing, including investigating the safety and feasibility of extending uranium recovery licences from ten to 20 years' duration, and directs the Department of Energy, which oversees nuclear cleanup and related projects, to issue at least every ten years a long-term plan detailing the management of its excess uranium inventories.

Maria Korsnick, president and CEO of the US Nuclear Energy Institute, described NEIMA as a "significant, positive step" toward the reform of the NRC's fee collection process. "This legislation establishes a more equitable and transparent funding structure which will benefit all operating reactors and future licensees," she said. "The bill also reaffirms Congress’s support for nuclear innovation by working to establish an efficient and stable regulatory structure that is prepared to license the advanced reactors of the future."

Marilyn Kray, president-elect of the American Nuclear Society, said the passage of the legislation was a "big win" for the nation and its nuclear community. "By reforming outdated laws, NRC will now be able to invest more freely in advanced nuclear R&D and licensing activities. This in turn will accelerate deployment of cutting-edge American nuclear systems and better prepare the next generation of nuclear engineers and technologists," she said.

The bill was introduced in 2017 by Senator John Barrasso of Wyoming. It was approved by Congress on 21 December by 361 votes to 10, having been passed by the Senate the previous day, even as later Biden's climate law developments produced mixed results.

NEIMA is one of several bipartisan bills that support advanced nuclear innovation considered by the 115th US Congress, which ended on 2 January. These are: the Nuclear Energy Innovation Capabilities Act (NEICA); the Nuclear Energy Leadership Act; the Nuclear Utilisation of Keynote Energy Act; the Advanced Nuclear Fuel Availability Act, a focus sharpened by the U.S. ban on Russian uranium in the fuel market; and legislation to expedite so-called part 810 approvals, which are needed for the export of technology, equipment and components. NEICA, which supports the deployment of advanced reactors and also directs the DOE to develop a reactor-based fast neutron source for the testing of advanced reactor fuels and materials, was signed into law in October.
