Alberta government tells utilities to prove fair costs

Five Nations Energy Transmission Line connects remote First Nations to the Ontario power grid, delivering clean, reliable electricity to Western James Bay through Indigenous-owned transmission infrastructure, replacing diesel generators and enabling sustainable community growth.

Key Points

An Indigenous-owned grid link providing reliable power to Western James Bay First Nations, replacing polluting diesel.

✅ Built by five First Nations; fully Indigenous-owned utility

✅ 270 km line connecting remote James Bay communities

✅ Ended diesel dependence; enabled sustainable development

For the Indigenous communities along northern Ontario’s James Bay — the ones that have lived on and taken care of the lands as long as anyone can remember — the new millenium marked the start of a diesel-less future, even as Ontario’s electricity outlook raised concerns about getting dirtier in policy debates. 

While the southern part of the province took Ontario’s power grid for granted, despite lessons from Europe’s power crisis about reliability, the vast majority of these communities had never been plugged in. Their only source of power was a handful of very loud diesel-powered generators. Because of that, daily life in the Attawapiskat, Kashechewan and Fort Albany First Nations involved deliberating a series of tradeoffs. Could you listen to the radio while toasting a piece of bread? How many Christmas lights could you connect before nothing else was usable? Was there enough power to open a new school? 

The communities wanted a safe, reliable, clean alternative, with Manitoba’s clean energy illustrating regional potential, too. So did their chiefs, which is why they passed a resolution in 1996 to connect the area to Ontario’s grid, not just for basic necessities but to facilitate growth and development, and improve their communities’ quality of life. 

The idea was unthinkable at the time — scorned and dismissed by those who held the keys to Ontario’s (electrical) power, much like independent power projects can be in other jurisdictions. Even some in the community didn’t fully understand it. When the idea was first proposed at a gathering of Nishnawbe Aski Nation, which represents 49 First Nations, one attendee said the only way he could picture the connection was as “a little extension cord running through the bush from Moosonee.” 

But the leadership of Attawapiskat, Kashechewan and Fort Albany First Nations had been dreaming and planning. In 1997, along with members of Taykwa Tagamou and Moose Cree First Nations, they created the first, and thus far only, fully Indigenous-owned energy company in Canada: Five Nations Energy Inc., as partnerships like an OPG First Nation hydro project would later show in action, too. 

Over the next five years, the organization built Omushkego Ishkotayo, the Cree name for the Western James Bay transmission line: “Omushkego” refers to the Swampy Cree people, and “Ishkotayo” to hydroelectric power, while other regions were commissioning new BC generating stations in parallel. The 270-kilometre-long transmission line is in one of the most isolated regions of Ontario, one that can only be accessed by plane, except for a few months in winter when ice roads are strong enough to drive on. The project went online in 2001, bringing reliable power to over 7,000 people who were previously underserved by the province’s energy providers. It also, somewhat controversially, enabled Ontario’s first diamond mine in Attawapiskat territory.

The future the First Nations created 25 years ago is blissfully quiet, now that the diesel generators are shut off. “When the power went on, you could hear the birds,” Patrick Chilton, the CEO of Five Nations Energy, said with a smile. “Our communities were glowing.”

Power, politics and money: Five Nations Energy needed government, banks and builders on board
Chilton took over in 2013 after the former CEO, his brother Ed, passed away. “This was all his idea,” Chilton told The Narwhal in a conversation over Zoom from his office in Timmins, Ont. The company’s story has never been told before in full, he said, because he felt “vulnerable” to the forces that fought against Omushkego Ishkotayo or didn’t understand it, a dynamic underscored by Canada’s looming power problem reporting in recent years. 

The success of Five Nations Energy is a tale of unwavering determination and imagination, Chilton said, and it started with his older brother. “Ed was the first person who believed a transmission line was possible,” he said.

In a Timmins Daily Press death notice published July 2, 2013, Ed Chilton is described as having “a quiet but profound impact on the establishment of agreements and enterprises benefitting First Nations peoples and their lands.” Chilton doesn’t describe him that way, exactly. 

“If you knew my brother, he was very stubborn,” he said. A certified engineering technologist, Ed was a visionary whose whole life was defined by the transmission line. He was the first to approach the chiefs with the idea, the first to reach out to energy companies and government officials and the one who persuaded thousands of people in remote, underserved communities that it was possible to bring power to their region.

After that 1996 meeting of Nishnawbe Aski Nation, there came a four-year-long effort to convince the rest of Ontario, and the country, the project was possible and financially viable. The chiefs of the five First Nations took their idea to the halls of power: Queen’s Park, Parliament Hill and the provincial power distributor Hydro One (then Ontario Hydro). 

“All of them said no,” Chilton said. “They saw it as near to impossible — the idea that you could build a transmission line in the ‘swamp,’ as they called it.” The Five Nations Energy team kept a document at the time tracking how many times they heard no; it topped out at 37. 

One of the worst times was in 1998, at a meeting on the 19th floor of the Ontario Hydro building in the heart of downtown Toronto. There, despite all their preparation and planning, a senior member of the Ontario Hydro team told Chilton, Martin and other chiefs “you’ll build that line over my dead body,” Chilton recalled. 

At the time, Chilton said, Ontario Hydro was refusing to cooperate: unwilling to let go of its monopoly over transmission lines, but also saying it was unable to connect new houses in the First Nations to diesel generators it said were at maximum capacity. (Ontario Hydro no longer exists; Hydro One declined to comment.)

“There’s always naysayers no matter what you’re doing,” Martin said. “What we were doing had never been done before. So of course people were telling us how we had never managed something of this size or a budget of this size.” 

“[Our people] basically told them to blow it up your ass. We can do it,” Chilton said.

So the chiefs of the five nations did something they’d never done before: they went to all of the big banks and many, many charitable foundations trying to get the money, a big ask for a project of this scale, in this location. Without outside support, their pitch was that they’d build it themselves.

This was the hardest part of the process, said Lawrence Martin, the former Grand Chief of Mushkegowuk Tribal Council and a member of the Five Nations Energy board. “We didn’t know how to finance something like this, to get loans,” he told The Narwhal. “That was the toughest task for all of us to achieve.”

Eventually, they got nearly $50 million in funding from a series of financial organizations including the Bank of Montreal, Pacific and Western Capital, the Northern Ontario Heritage Fund Corporation (an Ontario government agency) and the engineering and construction company SNC Lavalin, which did an assessment of the area and deemed the project viable. 

And in 1999, Ed Chilton, other members of the Chilton family and the chiefs were able to secure an agreement with Ontario Hydro that would allow them to buy electricity from the province and sell it to their communities.

Smart Grid Modernization unites distributed energy resources, energy storage, EV charging, advanced metering, and bidirectional power flows to upgrade transmission and distribution infrastructure for reliability, resilience, cybersecurity, and affordable, clean power.

Key Points

Upgrading grid hardware and software to integrate DERs, storage, and EVs for a reliable and affordable power system.

✅ Enables DER, storage, and EV integration with bidirectional flows

✅ Improves reliability, resilience, and grid cybersecurity

✅ Requires early investment in sensors, inverters, and analytics

Much has been written, predicted, and debated in recent years about the future of the electricity system. The discussion isn’t simply about fossil fuels versus renewables, as often dominates mainstream energy discourse. Rather, the discussion is focused on something much larger and more fundamental: the very design of how and where electricity should be generated, delivered, and consumed.

Central to this discussion are arguments in support of, or in opposition to, the traditional model versus that of the decentralized or “emerging” model. But this is a false choice. The only choice that needs making is how to best transition to a smarter grid, and do so in a reliable and affordable manner that reflects grid modernization affordability concerns for utilities today. And the most effective and immediate means to accomplish that is to encourage and facilitate early investment in grid-related infrastructure and technology.

The traditional, or centralized, model has evolved since the days of Thomas Edison, but the basic structure is relatively unchanged: generate electrons at a central power plant, transmit them over a unidirectional system of high-voltage transmission lines, and deliver them to consumers through local distribution networks. The decentralized, or emerging, model envisions a system that moves away from the central power station as the primary provider of electricity to a system in which distributed energy resources, energy storage, electric vehicles, peer-to-peer transactions, connected appliances and devices, and sophisticated energy usage, pricing, and load management software play a more prominent role.

Whether it’s a fully decentralized and distributed power system, or the more likely centralized-decentralized hybrid, it is apparent that the way in which electricity is produced, delivered, and consumed will differ from today’s traditional model. And yet, in many ways, the fundamental design and engineering that makes up today’s electric grid will serve as the foundation for achieving a more distributed future. Indeed, as the transition to a smarter grid ramps up, the grid’s basic structure will remain the underlying commonality, allowing the grid to serve as a facilitator to integrate emerging technologies, including EV charging stations, rooftop solar, demand-side management software, and other distributed energy resources, while maximizing their potential benefits and informing discussions about California’s grid reliability under ambitious transition goals.

A loose analogy here is the internet. In its infancy, the internet was used primarily for sending and receiving email, doing homework, and looking up directions. At the time, it was never fully understood that the internet would create a range of services and products that would impact nearly every aspect of everyday life from online shopping, booking travel, and watching television to enabling the sharing economy and the emerging “Internet of Things.”

Uber, Netflix, Amazon, and Nest would not be possible without the internet. But the rapid evolution of the internet did not occur without significant investment in internet-related infrastructure. From dial-up to broadband to Wi-Fi, companies have invested billions of dollars to update and upgrade the system, allowing the internet to maximize its offerings and give way to technological breakthroughs, innovative businesses, and ways to share and communicate like never before.  

The electric grid is similar; it is both the backbone and the facilitator upon which the future of electricity can be built. If the vision for a smarter grid is to deploy advanced energy technologies, create new business models, and transform the way electricity is produced, distributed, and consumed, then updating and modernizing existing infrastructure and building out new intelligent infrastructure need to be top priorities. But this requires money. To be sure, increased investment in grid-related infrastructure is the key component to transitioning to a smarter grid; a grid capable of supporting and integrating advanced energy technologies within a more digital grid architecture that will result in a cleaner, more modern and efficient, and reliable and secure electricity system.

The inherent challenges of deploying new technologies and resources — reliability, bidirectional flow, intermittency, visibility, and communication, to name a few, as well as emerging climate resilience concerns shaping planning today, are not insurmountable and demonstrate exactly why federal and state authorities and electricity sector stakeholders should be planning for and making appropriate investment decisions now. My organization, Alliance for Innovation and Infrastructure, will release a report Wednesday addressing these challenges facing our infrastructure, and the opportunities a distributed smart grid would provide. From upgrading traditional wires and poles and integrating smart power inverters and real-time sensors to deploying advanced communications platforms and energy analytics software, there are numerous technologies currently available and capable of being deployed that warrant investment consideration.

Making these and similar investments will help to identify and resolve reliability issues earlier, and address vulnerabilities identified in the latest power grid report card findings, which in turn will create a stronger, more flexible grid that can then support additional emerging technologies, resulting in a system better able to address integration challenges. Doing so will ease the electricity evolution in the long-term and best realize the full reliability, economic, and environmental benefits that a smarter grid can offer.

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.

Air-gen Protein Nanowire Generator delivers clean energy by harvesting ambient humidity via Geobacter-derived conductive nanowires, generating continuous hydrovoltaic electricity through moisture gradients, electrodes, and proton diffusion for sustainable, low-waste power in diverse climates.

Key Points

A device using Geobacter protein nanowires to harvest humidity, producing continuous DC power via proton diffusion.

✅ 7 micrometer film between electrodes adsorbs water vapor.

✅ Output: ~0.5 V, 17 uA/cm2; stack units to scale power.

✅ Geobacter optimized via engineered E. coli for mass nanowires.

They found it buried in the muddy shores of the Potomac River more than three decades ago: a strange "sediment organism" that could do things nobody had ever seen before in bacteria.

This unusual microbe, belonging to the Geobacter genus, was first noted for its ability to produce magnetite in the absence of oxygen, but with time scientists found it could make other things too, like bacterial nanowires that conduct electricity.

For years, researchers have been trying to figure out ways to usefully exploit that natural gift, and they might have just hit pay-dirt with a device they're calling the Air-gen. According to the team, their device can create electricity out of… well, almost nothing, similar to power from falling snow reported elsewhere.

"We are literally making electricity out of thin air," says electrical engineer Jun Yao from the University of Massachusetts Amherst. "The Air-gen generates clean energy 24/7."

The claim may sound like an overstatement, but a new study by Yao and his team describes how the air-powered generator can indeed create electricity with nothing but the presence of air around it. It's all thanks to the electrically conductive protein nanowires produced by Geobacter (G. sulfurreducens, in this instance).

The Air-gen consists of a thin film of the protein nanowires measuring just 7 micrometres thick, positioned between two electrodes, referencing advances in near light-speed conduction in materials science, but also exposed to the air.

Because of that exposure, the nanowire film is able to adsorb water vapour that exists in the atmosphere, offering a contrast to legacy hydropower models, enabling the device to generate a continuous electrical current conducted between the two electrodes.

The team says the charge is likely created by a moisture gradient that creates a diffusion of protons in the nanowire material.

"This charge diffusion is expected to induce a counterbalancing electrical field or potential analogous to the resting membrane potential in biological systems," the authors explain in their study.

"A maintained moisture gradient, which is fundamentally different to anything seen in previous systems, explains the continuous voltage output from our nanowire device."

The discovery was made almost by accident, when Yao noticed devices he was experimenting with were conducting electricity seemingly all by themselves.

"I saw that when the nanowires were contacted with electrodes in a specific way the devices generated a current," Yao says.

"I found that exposure to atmospheric humidity was essential and that protein nanowires adsorbed water, producing a voltage gradient across the device."

Previous research has demonstrated hydrovoltaic power generation using other kinds of nanomaterials – such as graphene-based systems now under study – but those attempts have largely produced only short bursts of electricity, lasting perhaps only seconds.

By contrast, the Air-gen produces a sustained voltage of around 0.5 volts, with a current density of about 17 microamperes per square centimetre, and complementary fuel cell solutions can help keep batteries energized, with a current density of about 17 microamperes per square centimetre. That's not much energy, but the team says that connecting multiple devices could generate enough power to charge small devices like smartphones and other personal electronics – concepts akin to virtual power plants that aggregate distributed resources – all with no waste, and using nothing but ambient humidity (even in regions as dry as the Sahara Desert).

"The ultimate goal is to make large-scale systems," Yao says, explaining that future efforts could use the technology to power homes via nanowire incorporated into wall paint, supported by energy storage for microgrids to balance supply and demand.

"Once we get to an industrial scale for wire production, I fully expect that we can make large systems that will make a major contribution to sustainable energy production."

If there is a hold-up to realising this seemingly incredible potential, it's the limited amount of nanowire G. sulfurreducens produces.

Related research by one of the team – microbiologist Derek Lovley, who first identified Geobacter microbes back in the 1980s – could have a fix for that: genetically engineering other bugs, like E. coli, to perform the same trick in massive supplies.

"We turned E. coli into a protein nanowire factory," Lovley says.

"With this new scalable process, protein nanowire supply will no longer be a bottleneck to developing these applications."

Kakrapar Unit 3 700MWe PHWR achieved first criticality, showcasing indigenously designed nuclear power, NPCIL operations, Make in India manufacturing, advanced safety systems, grid integration, and closed-fuel-cycle strategy for India's expansion of pressurised heavy water reactors.

Key Points

India's first indigenous 700MWe PHWR at Kakrapar reached criticality, advancing NPCIL's Make in India nuclear power.

✅ First indigenous 700MWe PHWR achieves criticality

✅ NPCIL-built, Make in India components and contractors

✅ Advanced safety: passive decay heat removal, containment spray

Unit 3 of India’s Kakrapar nuclear plant in Gujarat achieved criticality on 22 July, as milestones at nuclear projects worldwide continue to be reached. It is India’s first indigenously designed 700MWe pressurised heavy water reactor (PHWR) to achieve this milestone.

Prime Minister Narendra Modi congratulated nuclear scientists, saying the reactor is a shining example of the 'Make in India' campaign and of the government's steps to get nuclear back on track in recent years, and a trailblazer for many such future achievements. 

India developed its own nuclear power generation technology as it faced sanctions from the international community following its first nuclear weapons test in in 1974. It has not signed the Nuclear Non-Proliferation Treaty, while China's nuclear energy development is on a steady track according to experts. India has developed a three-stage nuclear programme based on a closed-fuel cycle, where the used fuel of one stage is reprocessed to produce fuel for the next stage.

Kakrapar 3 was developed and is operated by state-owned Nuclear Power Corporation of India Ltd (NPCIL), while in Europe KHNP considered for a Bulgarian project as countries weigh options. The first two units are 220MWe PHWRs commissioned in 1993 and 1995. NPCIL said in a statement that the components and equipment for Kakrapur 3 were “manufactured by lndian industries and the construction and erection was undertaken by various lndian contractors”.

The 700MWe PHWRs have advanced safety features such as steel lined inner containment, a passive decay heat removal system, a containment spray system, hydrogen management systems etc, the statement added.

Fuel loading was completed by mid-March, a crucial step in Abu Dhabi during its commissioning as well. “Thereafter, many tests and procedures were carried out during the lockdown period following all COVlD-19 guidelines.”

“As a next step, various experiments / tests will be conducted and power will be increased progressively, a path also followed by Barakah Unit 1 reaching 100% power before commercial operations.” Kakrapur 3 will be connected to the western grid and will be India’s 23rd nuclear power reactor.

Kakrapur 3 “is the front runner in a series of 16 indigenous 700MWe PHWRs which have been accorded administrative approval and financial sanction by the government and are at various stages of implementation”. Five similar units are under construction at Kakarapur 4, Rajasthan 7&8 and Gorakhpur1&2.

DAE said in January 2019 that India planned to put 21 new nuclear units with a combined generating capacity of 15,700MWe into operation by 2031, including ten indigenously designed PHWRs, while Bangladesh develops nuclear power with IAEA assistance.

California Heat Wave Grid Emergency sees CAISO issue Stage 3 alerts as record demand, extreme heat, and climate change strain renewable energy; conservation efforts avert rolling blackouts and protect grid reliability statewide.

Key Points

A grid emergency in California's heat wave, with CAISO Stage 3 alerts amid record demand and risk of rolling blackouts.

✅ CAISO triggered Stage 3 alerts, then downgraded by 8 pm PT

✅ Record 52,061 MW demand; conservation reduced grid stress

✅ Extreme heat and climate change heightened outage risks

California has avoided ordering rolling blackouts after electricity demand reached a record-high Tuesday night from excessive heat across the state, even as energy experts warn the U.S. grid faces mounting climate stresses. 

The California Independent System Operator, which oversees the state’s electrical grid, imposed its highest level energy emergency on Tuesday, a step that comes before ordering rolling blackouts and allows the state to access emergency power sources.

The Office of Emergency Services also sent a text alert to residents requesting them to conserve power. The operator downgraded the Stage 3 alert around 8:00 p.m. PT on Tuesday and said that “consumer conservation played a big part in protecting electric grid reliability,” and in bolstering grid resilience overall.

The state capital of Sacramento reached 116 degrees Fahrenheit on Tuesday, according to the National Weather Service, surpassing a record that was set almost 100 years ago. And nearly a half-dozen cities in the San Francisco Bay Area tied or set all-time highs, the agency said.

CAISO said peak power demand on Tuesday reached 52,061 megawatts, surpassing a previous high of 50,270 megawatts on July 24, 2006, while nearby B.C. electricity demand has also hit records during extreme weather.

While the operator did not order rolling blackouts, three Northern California cities saw brief power outages, and severe storms have caused similar disruptions statewide in recent months. As of 7:00 am PT on Wednesday, nearly 8,000 customers in California were without power, according to PowerOutage.us. 

Gov. Gavin Newsom, in a Twitter video on Tuesday, warned the temperatures across California were unprecedented and the state is headed into the worst part of the heat wave, which is on track to be the hottest and longest on record for September.

“The risk for outages is real and it’s immediate,” Newsom said. “These triple-digit temperatures throughout much of the state are leading, not surprisingly, to record demand on the energy grid.”

The governor urged residents to pre-cool their homes earlier in the day when more power is available and turn thermostats to 78 degrees or higher after 4:00 pm PT. “Everyone has to do their part to help step up for just a few more days,” Newsom said.

The possibility for widespread outages reflects how power grids in California and other states are becoming more vulnerable to climate-related disasters such as heat waves, storms and wildfires across California.

California, which has set a goal to transition to 100% carbon-free electricity by 2045, has shuttered a slew of gas power plants in the past few years, leaving the state increasingly dependent on solar energy.

At times, the state has produced a clean energy surplus during peak solar generation, underscoring the challenges of balancing supply and demand.

The megadrought in the American West has generated the driest two decades in the region in at least 1,200 years, and human-caused climate change has fueled the problem, scientists said earlier this year. Conditions will likely continue through 2022 and persist for years.
