U.S. researchers say they've found a material that can generate electricity from the waste heat of car exhaust systems or industrial processes and equipment.

Researchers at Northwestern University placed nanocrystals of rock salt into lead telluride to create a material that is expected to be able to convert 14 percent of heat waste to electricity, a university release said recently.

"It has been known for 100 years that semiconductors have this property that can harness electricity," chemistry Professor Mercouri Kanatzidis said. "To make this an efficient process, all you need is the right material, and we have found a recipe or system to make this material."

"We can put this material inside of an inexpensive device with a few electrical wires and attach it to something like a light bulb," said Vinayak Dravid, professor of materials science and engineering and co-author of the paper. "The device can make the light bulb more efficient by taking the heat it generates and converting part of the heat, 10 to 15 percent, into a more useful energy like electricity."

Automotive, chemical, brick, glass and other industries that use heat to make products could make their systems more efficient with the use of this scientific discovery, Kanatzidis said.

Niagara Falls Powerhouse Gets a Billion-Dollar Upgrade for the 21st Century

Sir Adam Beck I refurbishment boosts hydropower capacity in Niagara, upgrading turbines, generators, and controls for Ontario Power Generation. The billion-dollar project enhances grid reliability, clean energy output, and preserves heritage architecture.

 

Key Points

An OPG upgrade of the historic Niagara plant to replace equipment, add 150 MW, and extend clean power life.

✅ Adds at least 150 MW to Ontario's clean energy supply

✅ Replaces turbines, generators, transformers, and controls

✅ Creates hundreds of skilled construction and engineering jobs

 

Ontario's iconic Sir Adam Beck hydroelectric generating station in Niagara is set to undergo a massive, billion-dollar refurbishment. The project will significantly boost the power station's capacity and extend its lifespan, with efforts similar to revitalizing older dams seen across North America, ensuring a reliable supply of clean energy for decades to come.


A Century of Power Generation

The Sir Adam Beck generating stations have played a pivotal role in Ontario's power grid for over a century. The first generating station, Sir Adam Beck I, went online in 1922, followed by Sir Adam Beck II in 1954. A third station, the Sir Adam Beck Pump Generating Station, was added in 1957, highlighting the role of pumped storage in Ontario for grid flexibility, Collectively, they form one of the largest hydroelectric complexes in the world, harnessing the power of the Niagara River.


Preparing for Increased Demand

The planned refurbishment of Sir Adam Beck I is part of Ontario Power Generation's broader strategy, which includes the life extension at Pickering NGS among other initiatives, to meet the growing energy demands of the province. With the population expanding and a shift towards electrification, Ontario will need to increase its power generation capacity while also focusing on sustainable and clean sources of energy.


Billions to Secure Sustainable Energy

The project to upgrade Sir Adam Beck I carries a hefty price tag of over a billion dollars but is considered a vital investment in Ontario's energy infrastructure, and recent OPG financial results underscore the utility's capacity to manage long-term capital plans. The refurbishment will see the replacement of aging turbines, generators, and transformers, and a significant upgrade to the station's control systems. Following the refurbishment, the output of Sir Adam Beck I is expected to increase by at least 150 megawatts – enough to power thousands of homes and businesses.


Creating Green Jobs

In addition to securing the province's energy future, the upgrade presents significant economic benefits to the Niagara region. The project will create hundreds of well-paying construction and engineering jobs, similar to employment from the continued operation of Pickering Station across Ontario, during the several years it will take to implement the upgrades.


Commitment to Hydropower

Ontario Power Generation (OPG) has long touted the benefits of hydropower as a reliable, renewable, and affordable source of energy, even as an analysis of rising grid emissions underscores the importance of clean generation to meet demand. The Sir Adam Beck complex is a shining example and represents a significant asset in the fight against climate change while providing reliable power to Ontario's businesses and residents.


Balancing Energy Needs with Heritage Preservation

The refurbishment will also carefully integrate modern design with the station's heritage elements, paralleling decisions such as the refurbishment of Pickering B that weigh system needs and public trust. Sir Adam Beck I is a designated historic site, and the project aims to preserve the station's architectural significance while enhancing its energy generation capabilities.

$453M Manitoba Hydro line to Minnesota could face delay after energy board recommendation

Manitoba-Minnesota Transmission Project faces NEB certificate review, with public hearings, Indigenous consultation, and cross-border approval weighing permit vs certificate timelines, potential land expropriation, and Hydro's 2020 in-service date for the 308-MW intertie.

 

Key Points

A cross-border hydro line linking Manitoba and Minnesota, now under NEB review through a permit or certificate process.

✅ NEB recommends certificate with public hearings and cabinet approval

✅ Stakeholders cite land, health, and economic impacts along route

✅ Hydro targets May-June 2020 in-service despite review

 

A recommendation from the National Energy Board could push back the construction start date of a $453-million hydroelectric transmission line from Manitoba to Minnesota.

In a letter to federal Natural Resources Minister Jim Carr, the regulatory agency recommends using a "certificate" approval process, which could take more time than the simpler "permit" process Manitoba Hydro favours.

The certificate process involves public hearings, reflecting First Nations intervention seen in other power-line debates, to weigh the merits of the project, which would then go to the federal cabinet for approval.

The NEB says this process would allow for more procedural flexibility and "address Aboriginal concerns that may arise in the circumstances of this process."

The Manitoba-Minnesota Transmission Project would provide the final link in a chain that brings hydroelectricity from generating stations in northern Manitoba, through the Bipole III transmission line and, like the New England Clean Power Link project, across the U.S. border as part of a 308-megawatt deal with the Green Bay-based Wisconsin Public Service.

When Hydro filed its application in December 2016, it had expected to have approval by the end of August 2017 and to begin construction on the line in mid-December, in order to have the line in operation by May or June 2020.  

Groups representing stakeholders along the proposed route of the transmission line had mixed reactions to the energy board's recommendation.

A lawyer representing a coalition of more than 120 landowners in the Rural Municipality of Taché and around La Broquerie, Man., welcomed the opportunity to have a more "fulsome" discussion about the project.

"I think it's a positive step. As people become more familiar with the project, the deficiencies with it become more obvious," said Kevin Toyne, who represents the Southeast Stakeholders Coalition.

Toyne said some coalition members are worried that Hydro will forcibly expropriate land in order to build the line, while others are worried about potential economic and health impacts of having the line so close to their homes. They have proposed moving the line farther east.

When the Clean Environment Commission — an arm's-length provincial government agency — held public hearings on the proposed route earlier this year, the coalition brought their concerns forward, echoing Site C opposition voiced by northerners, but Toyne says both the commission and Hydro ignored them.

Hydro still aiming for 2020 in-service date

The Manitoba Métis Federation also participated in those public hearings. MMF president David Chartrand worries about the impact a possible delay, as seen with the Site C work halt tied to treaty rights, could have on revenue from sales of hydroelectric power to the U.S.

"I know that a lot of money, billions have been invested on this line. And if the connection line is not done, then of course this will be sitting here, not gaining any revenue, which will affect every Métis in this province, given our Hydro bill's going to go up," Chartrand said.The NEB letter to Minister Carr requests that he "determine this matter in an expedited manner."

Manitoba Hydro spokesperson Bruce Owen said in an email that the Crown corporation will participate in whatever process, permit or certificate, the NEB takes.

"Manitoba Hydro does not have any information at this point in time that would change the estimated in-service date (May-June 2020) for the Manitoba-Minnesota Transmission Project," he said.

The federal government "is currently reviewing the NEB's recommendation to designate the project as subject to a certificate, which would result in public hearings," said Alexandre Deslongchamps, a spokesperson for Carr.

"Under the National Energy Board Act, an international power line requires either the approval by the NEB through a permit or approval by the Government of Canada by a certificate. Both must be issued by the NEB," he wrote in an email to CBC News.

By law, the certificate process is not to take longer than 15 months.

Electricity deal clinches $100M bitcoin mining operation in Medicine Hat

Medicine Hat Bitcoin Mining Deal delivers 42 MW electricity to Hut 8, enabling blockchain data centres, cryptocurrency mining expansion, and economic diversification in Alberta with low-cost power, land lease, and rapid construction near Unit 16.

 

Key Points

A pact to supply 42 MW and lease land, enabling Hut 8's blockchain data centres and crypto mining growth in Alberta.

✅ 42 MW electricity from city; land lease near Unit 16

✅ Hut 8 expands to 60.7 MW; blockchain data centres

✅ 100 temporary jobs; 42 ongoing roles in Alberta

 

The City of Medicine Hat has agreed to supply electricity and lease land to a Toronto-based cryptocurrency mining company, at a time when some provinces are pausing large new crypto loads in a deal that will see $100 million in construction spending in the southern Alberta city.

The city will provide electric energy capacity of about 42 megawatts to Hut 8 Mining Corp., which will construct bitcoin mining facilities near the city's new Unit 16 power plant.

The operation is expected to be running by September and will triple the company's operating power to 60.7 megawatts, Hut 8 said, amid broader investments in new turbines across Canada.

"The signing of the electricity supply agreement and the land lease represents a key component in achieving our business plan for the roll-out of our BlockBox Data Centres in low-cost energy jurisdictions," said the company's board chairman, Bill Tai, in a release.

"[Medicine Hat] offers stable, cost-competitive utility rates and has been very welcoming and supportive of Hut 8's fast-paced growth plans."

In bitcoin mining operations, rows upon rows of power-consuming computers are used to solve mathematical puzzles in exchange for bitcoins and confirm crytopcurrency transactions. The verified transactions are then added to the public ledger known as the blockchain.

Hut 8's existing 18.7-megawatt mining operation at Drumheller, Alta. — a gated compound filled with rows of shipping containers housing the computers — has so far mined 750 bitcoins. Bitcoin was trading Tuesday morning for about $11,180.

Medicine Hat Mayor Ted Clugston says the deal is part of the city's efforts to diversify its economy.

We've made economic development a huge priority down here because we were hit very, very hard by the oil and gas decline," he said, noting that being the generator and vendor of its own electricity puts the city in a uniquely good position.

"Really we're just turning gas into electricity and they're taking that electricity and turning it into blockchain, or ones and zeroes."

Elsewhere in Canada, using more electricity for heat has been urged by green energy advocates, reflecting broader electrification debates.

Hut 8 says construction of the facility is starting right away and will create about 100 temporary jobs. The project is expected to be finished by the third-quarter of this year.

The Medicine Hat mining operation will generate 42 ongoing jobs for electricians, general labourers, systems technicians and security staff.

Ford Threatens to Cut U.S. Electricity Exports Amid Trade Tensions

Ontario Electricity Export Retaliation signals tariff-fueled trade tensions as Doug Ford leverages cross-border energy flows to the U.S., risking grid reliability, higher power prices, and escalating a Canada-U.S. trade war over protectionist policies.

 

Key Points

A policy threat by Ontario to cut power exports to U.S. states in response to tariffs, leveraging grid dependence.

✅ Powers about 1.5M U.S. homes in NY, MI, and MN

✅ Risks price spikes, shortages, and legal challenges

✅ Part of Canada's CAD 30B retaliatory tariff package

 

In a move that underscores the escalating trade tensions between Canada and the United States, Ontario Premier Doug Ford has threatened to halt electricity exports to U.S. states in retaliation for the Trump administration's recent tariffs. This bold stance highlights Ontario's significant role in powering regions across the U.S. and serves as a warning about the potential consequences of trade disputes.

The Leverage of Ontario's Electricity

Ontario's electricity exports are not merely supplementary; they are essential to the energy supply of several U.S. states. The province provides power to approximately 1.5 million homes in states such as New York, Michigan, and Minnesota, even as it eyes energy independence through domestic initiatives. This substantial export positions Ontario as a key player in the regional energy market, giving the province considerable leverage in trade negotiations.

Premier Ford's Ultimatum

Responding to the Trump administration's imposition of a 25% tariff on Canadian imports, Premier Ford, following a Washington meeting, declared, "If they want to play tough, we can play tough." He further emphasized his readiness to act, stating, "I’ll cut them off with a smile on my face." This rhetoric underscores Ontario's willingness to use its energy exports as a bargaining chip in the trade dispute.

Economic and Political Ramifications

The potential cessation of electricity exports to the U.S. would have profound economic implications. U.S. states that rely on Ontario's power could face energy shortages, leading to increased prices, particularly New York energy prices, and potential disruptions. Such an action would not only strain the energy supply but also escalate political tensions, potentially affecting other areas of bilateral cooperation.

Canada's Retaliatory Measures

Ontario's threat is part of a broader Canadian strategy to counteract U.S. tariffs. Prime Minister Justin Trudeau has announced retaliatory tariffs on U.S. goods worth approximately CAD 30 billion, targeting products such as food, textiles, and furniture. These measures aim to pressure the U.S. administration into reconsidering its trade policies.

The Risk of Escalation

While leveraging energy exports provides Ontario with a potent tool, it also carries significant risks, as experts warn against cutting Quebec's energy exports amid tariff tensions. Such actions could lead to a full-blown trade war, with both countries imposing tariffs and export restrictions. The resulting economic fallout could affect various sectors, from manufacturing to agriculture, and lead to job losses and increased consumer prices.

International Trade Relations

The dispute also raises questions about the stability of international trade agreements and the rules governing cross-border energy transactions. Both Canada and the U.S. are signatories to various trade agreements that promote the free flow of goods and services, including energy. Actions like export bans could violate these agreements and lead to legal challenges.

Public Sentiment and Nationalism

The trade tensions have sparked a surge in Canadian nationalism, with public sentiment largely supporting tariffs on energy and minerals as retaliatory measures. This sentiment is evident in actions such as boycotting American products and expressing discontent at public events. However, while national pride is a unifying force, it does not mitigate the potential economic hardships that may result from prolonged trade disputes.

The Path Forward

Navigating this complex situation requires careful diplomacy and negotiation. Both Canada and the U.S. must weigh the benefits of trade against the potential costs of escalating tensions. Engaging in dialogue, seeking compromise, and adhering to international trade laws are essential steps to prevent further deterioration of relations and to ensure the stability of both economies.

Ontario's threat to cut off electricity exports to the U.S. serves as a stark reminder of the interconnectedness of global trade and the potential consequences of protectionist policies. While such measures can be effective in drawing attention to grievances, they also risk significant economic and political fallout. As the situation develops, it will be crucial to monitor the responses of both governments and the impact on industries and consumers alike, including growing support for Canadian energy projects among stakeholders.

Oil crash only a foretaste of what awaits energy industry

Oil and Gas Profitability Decline reflects shale-driven oversupply, OPEC-Russia dynamics, LNG exports, renewables growth, and weak demand, signaling compressed margins for producers, stressed petrodollar budgets, and shifting energy markets post-Covid.

 

Key Points

A sustained squeeze on hydrocarbon margins from agile shale supply, weaker OPEC leverage, and expanding renewables.

✅ Shale responsiveness caps prices and erodes industry rents

✅ OPEC-Russia cuts face limited impact versus US supply

✅ Renewables and EVs slow long-term oil and gas demand

 

The oil-price crash of March 2020 will probably not last long. As in 2014, when the oil price dropped below $50 from $110 in a few weeks, this one will trigger a temporary collapse of the US shale industry. Unless the coronavirus outbreak causes Armageddon, cheap oil will also support policymakers’ efforts to help the global economy.

But there will be at least one important and lasting difference this time round — and it has major market and geopolitical implications.

The oil price crash is a foretaste of where the whole energy sector was going anyway — and that is down.

It may not look that way at first. Saudi Arabia will soon realise, as it did in 2015, that its lethal decision to pump more oil is not only killing US shale but its public finances as well. Riyadh will soon knock on Moscow’s door again. Once American shale supplies collapse, Russia will resume co-operation with Saudi Arabia.

With the world economy recovering from the Covid-19 crisis by then, and with electricity demand during COVID-19 shifting, moderate supply cuts by both countries will accelerate oil market recovery. In time, US shale producers will return too.

Yet this inevitable bounceback should not distract from two fundamental factors that were already remaking oil and gas markets. First, the shale revolution has fundamentally eroded industry profitability. Second, the renewables’ revolution will continue to depress growth in demand.

The combined result has put the profitability of the entire global hydrocarbon industry under pressure. That means fewer petrodollars to support oil-producing countries’ national budgets, including Canada's oil sector exposures. It also means less profitable oil companies, which traditionally make up a large segment of stock markets, an important component of so many western pension funds.

Start with the first factor to see why this is so. Historically, the geological advantages that made oil from countries such as Saudi Arabia so cheap to produce were unique. Because oil and gas were produced at costs far below the market price, the excess profits, or “rent”, enjoyed by the industry were very large.

Furthermore, collusion among low-cost producers has been a winning strategy. The loss of market share through output cuts was more than compensated by immediately higher prices. It was the raison d’être of Opec.

The US shale revolution changed all this, exposing the limits of U.S. energy dominance narratives. A large oil-producing region emerged with a remarkable ability to respond quickly to price changes and shrink its costs over time. Cutting back cheap Opec oil now only increases US supplies, with little effect on world prices.

That is why Russia refused to cut production this month. Even if its cuts did boost world prices — doubtful given the coronavirus outbreak’s huge shock to demand — that would slow the shrinkage of US shale that Moscow wants.

Shale has affected the natural gas industry even more. Exports of US liquefied natural gas now put an effective ceiling on global prices, and debates over a clean electricity push have intensified when gas prices spike.

On top of all this, there is also the renewables’ revolution, though a green revolution has not been guaranteed in the near term. Around the world, wind and solar have become ever-cheaper options to generate electricity. Storage costs have also dropped and network management improved. Even in the US, renewables are displacing coal and gas. Electrification of vehicle fleets will damp demand further, as U.S. electricity, gas, and EVs face evolving pressures.

Eliminating fossil fuel consumption completely would require sustained and costly government intervention, and reliability challenges such as coal and nuclear disruptions add to the complexity. That is far from certain. Meanwhile, though, market forces are depressing the sector’s usual profitability.

The end of oil and gas is not immediately around the corner. Still, the end of hydrocarbons as a lucrative industry is a distinct possibility. We are seeing that in dramatic form in the current oil price crash. But this collapse is merely a message from the future.

Energy Ministry may lower coal production target as Chinese demand falls

Indonesia Coal Production Cuts reflect weaker China demand, COVID-19 impacts, falling HBA reference prices, and DMO sales to PLN, pressuring thermal coal output, miner budgets, and investment plans under the 2020 RKAB.

 

Key Points

Planned 2020 coal output reductions from China demand slump, lower HBA prices, and DMO constraints impacting miners.

✅ China demand drop reduces exports and thermal coal shipments.

✅ HBA reference price decline pressures margins and cash flow.

✅ DMO sales to PLN limit revenue; investment plans may slow.

 

The Energy and Mineral Resources (ESDM) Ministry is considering lowering the coal production target this year as demand from China has shown a significant decline, with China power demand drops reported, since the start of the outbreak of the novel coronavirus in the country late last year, a senior ministry official has said.

The ministry’s coal and mineral director general Bambang Gatot Ariyono said in Jakarta on March 12 that the decline in the demand had also caused a sharp drop in coal prices on the world market, and China's plan to reduce coal power has further weighed on sentiment, which could cause the country’s miners to reduce their production.

The 2020 minerals and coal mining program and budget (RKAB) has set a current production goal of 550 million tons of coal, a 10 percent increase from last year’s target. As of March 6, 94.7 million tons of coal had been mined in the country in the year.

“With the existing demand, revision to this year’s production is almost certain,” he said, adding that the drop in demand had also caused a decline in coal prices.

Indonesia’s thermal coal reference price (HBA) fell by 26 percent year-on-year to US$67.08 per metric ton in March, according to a Standards & Poor press release on March 5.  At home, the coal price is also unattractive for local producers. Under the domestic market obligation (DMO) policy, miners are required to sell a quarter of their production to state-owned electricity company PLN at a government-set price, even as imported coal volumes rise in some markets. This year’s coal reference price is $70 per metric ton, far below the internal prices before the coronavirus outbreak hit China.

The ministry’s expert staff member Irwandy Arif said China had reduced its coal demand by 200,000 tons so far, as six of its coal-fired power plants had suspended operation due to the significant drop in electricity demand. Many factories in the country were closed as the government tried to halt the spread of the new coronavirus, which caused the decline in energy demand and created electric power woes for international supply chains.

“At present, all mines in Indonesia are still operating normally, while India is rationing coal supplies amid surging electricity demand. But we have to see what will happen in June,” he said.

The ministry predicted that the low demand would also result in a decline in coal mining investment, as clean energy investment has slipped across many developing nations.

The ministry set a $7.6 billion investment target for the mining sector this year, up from $6.17 billion last year, even as Israel reduces coal use in its power sector, which may influence regional demand. The year’s total investment realization was $192 million as of March 6, or around 2.5 percent of the annual target.
