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.

USAID Delivers Mobile Gas Turbine Power Plant to Ukraine

USAID GE Mobile Power Plant Ukraine supplies 28MW of emergency power and distributed generation to bolster energy security, grid resilience, and critical infrastructure reliability across cities and regions amid ongoing attacks.

 

Key Points

A 28MW GE gas turbine from USAID providing mobile, distributed power to strengthen Ukraine's grid resilience.

✅ 28MW GE gas turbine; power for 100,000 homes

✅ Mobile deployment to cities and regions as needed

✅ Supports hospitals, schools, and critical infrastructure

 

Deputy U.S. Administrator Isobel Coleman announced during her visit to Kyiv that the U.S. Agency for International Development (USAID) has provided the Government of Ukraine with a mobile gas turbine power plant purchased from General Electric (GE), as discussions of a possible agreement on power plant attacks continue among stakeholders.

The mobile power plant was manufactured in the United States by GE’s Gas Power business and has a total output capacity of approximately 28MW, which is enough to provide the equivalent electricity to at least 100,000 homes. This will help Ukraine increase the supply of electricity to homes, hospitals, schools, critical infrastructure providers, and other institutions, as the country has even resumed electricity exports in recent months. The mobile power plant can be operated in different cities or regions depending on need, strengthening Ukraine’s energy security amid the Russian Federation’s continuing strikes against critical infrastructure.   

Since the February 2022 full-scale invasion of Ukraine, and particularly since October 2022, the Russian Federation has deliberately targeted critical civilian heating, power, and gas infrastructure in an effort to weaponize the winter, raising nuclear risks to grid stability noted by international monitors. Ukraine has demonstrated tremendous resilience in the wake of these attacks, with utility workers routinely risking their lives to repair the damage, often within hours of air strikes, even as Russia builds power lines to reactivate the Zaporizhzhia plant to influence the energy situation.

The collaboration between USAID and GE reflects the U.S. government’s emphasis on engaging American private sector expertise and procuring proven and reliable equipment to meet Ukraine’s needs. Since the start of Putin’s full-scale war against Ukraine, USAID has both directly procured equipment for Ukraine from American companies and engaged the private sector in partnerships to meet Ukraine’s urgent wartime needs, with U.S. policy debates such as a proposal on Ukraine’s nuclear plants drawing scrutiny.

This mobile power plant is the latest example of USAID assistance to Ukraine’s energy sector since the start of the Russian Federation’s full-scale invasion, during which Ukraine has resumed electricity exports as conditions improved. USAID has already delivered more than 1,700 generators to 22 oblasts across Ukraine, with many more on the way. These generators ensure electricity and heating for schools, hospitals, accommodation centers for internally-displaced persons, district heating companies, and water systems if and when power is knocked out by the Russian Federation’s relentless, systematic and cruel attacks against critical civil infrastructure. USAID has invested $55 million in Ukraine’s heating infrastructure to help the Ukrainian people get through winter. This support will benefit up to seven million Ukrainians by supporting repairs and maintenance of pipes and other equipment necessary to deliver heating to homes, hospitals, schools, and businesses across Ukraine. USAID’s assistance builds on over two decades of support to Ukraine to strengthen the country’s energy security, complementing growth in wind power that is harder to destroy.

Trump's Order Boosts U.S. Uranium and Nuclear Energy

Uranium Critical Mineral Reclassification signals a US executive order directing USGS to restore critical status, boosting nuclear energy, domestic uranium mining, streamlined permitting, federal support, and energy security amid import reliance and supply chain risks.

 

Key Points

A policy relisting uranium as a critical mineral to unlock funding, speed permits, and strengthen U.S. nuclear security.

✅ Directs Interior to have USGS reconsider uranium classification

✅ Speeds permits for domestic uranium mining projects

✅ Targets import dependence and strengthens energy security

 

In a strategic move to bolster the United States' nuclear energy sector, former President Donald Trump issued an executive order on January 20, 2025, directing the Secretary of the Interior to instruct the U.S. Geological Survey (USGS) to reconsider classifying uranium as a critical mineral. This directive aims to enhance federal support and streamline permitting processes for domestic uranium projects, thereby strengthening U.S. energy security objectives.

Reclassification of Uranium as a Critical Mineral

The USGS had previously removed uranium from its critical minerals list in 2022, categorizing it as a "fuel mineral" that did not qualify for such designation. The recent executive order seeks to reverse this decision, recognizing uranium's strategic importance in the context of the nation's energy infrastructure and geopolitical considerations.

Implications for Domestic Uranium Production

Reclassifying uranium as a critical mineral is expected to unlock federal funding and expedite the permitting process for uranium mining projects within the United States. This initiative is particularly pertinent given the significant decline in domestic uranium production over the past two decades. According to the U.S. Energy Information Administration, domestic production has decreased by 96%, from 4.8 million pounds in 2014 to approximately 121,296 pounds in the third quarter of 2024.

Current Uranium Supply Dynamics

Despite the push for increased domestic production, the U.S. remains heavily reliant on uranium imports. In 2022, 27% of U.S. uranium purchases were sourced from Canada, with an additional 57% imported from countries including Kazakhstan, Uzbekistan, Australia, and Russia; a recent ban on Russian uranium could further disrupt these supply patterns and heighten risks. This reliance on foreign sources has raised concerns about energy security, especially in light of recent geopolitical tensions.

Challenges and Considerations

While the executive order represents a significant step toward revitalizing the U.S. nuclear energy sector, several challenges persist, and energy dominance faces constraints that will shape implementation:

  • Regulatory Hurdles: Accelerating the permitting process for uranium mining projects involves navigating complex environmental and regulatory frameworks, though recent permitting reforms for geothermal hint at potential pathways, which can be time-consuming and contentious.

  • Market Dynamics: The uranium market is subject to global supply and demand fluctuations, and domestic producers may face competition from established international suppliers.

  • Infrastructure Development: Expanding domestic uranium production necessitates substantial investment in mining infrastructure and workforce development, areas that have been underfunded in recent years.

Broader Implications for Nuclear Energy Policy

The executive order aligns with a broader strategy to revitalize the U.S. nuclear energy industry, where ongoing nuclear innovation is critical to delivering stable, low-emission power. The increasing demand for nuclear energy is driven by the global push for zero-emissions energy sources and the need to support power-intensive technologies, such as artificial intelligence servers.

Former President Trump's executive order to reclassify uranium as a critical mineral, aligning with his broader energy agenda and a prior pledge to end the 'war on coal', signifies a pivotal moment for the U.S. nuclear energy sector. By potentially unlocking federal support, including programs advanced by the Nuclear Innovation Act, and streamlining permitting processes, this initiative aims to reduce dependence on foreign uranium sources and enhance national energy security. However, realizing these objectives will require addressing regulatory challenges, market dynamics, and infrastructure needs to ensure the successful revitalization of the domestic uranium industry.

California avoids widespread rolling blackouts as heat strains power grid

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.

NB Power launches public charging network for EVs

NB Power eCharge Network expands EV charging in New Brunswick with fast chargers, level 2 stations, Trans-Canada Highway coverage, and green infrastructure, enabling worry-free electric vehicle travel and lower emissions across the province.

 

Key Points

NB Power eCharge Network is a provincewide EV charging system with fast and level 2 stations for reliable travel.

✅ 15 fast-charging sites on Trans-Canada and northern New Brunswick

✅ Level 2 stations at highways, municipalities, and businesses

✅ 20-30 minute DC fast charging; cut emissions ~80% and fuel ~75%

 

NB Power announced Friday the eCharge Network, the province’s first electric vehicle charging network aimed at giving drivers worry-free travel everywhere in the province.

The network includes 15 locations along the province’s busiest highways where both fast-chargers and level-2 chargers will be available. In addition, nine level-2 chargers are already located at participating municipalities and businesses throughout the province. The new locations will be installed by the end of 2017.

NB Power is working with public and private partners to add to the network to enable electric vehicle owners to drive with confidence and to encourage others to make the switch from gas to electric vehicles, supported by a provincial rebate program now available.

“We are incredibly proud to offer our customers and visitors to New Brunswick convenient charging with the launch of our eCharge Network,” said Gaëtan Thomas, president and CEO of NB Power. “Our goal is to make it easy for owners of electric vehicles to drive wherever they choose in New Brunswick, and to encourage more drivers to consider an electric vehicle for their next purchase.”

An electric vehicle owner in New Brunswick can shrink their vehicle carbon footprint by about 80 per cent while reducing their fuel-related costs by about 75 per cent, according to NB Power, and broader grid benefits are being explored through Nova Scotia's vehicle-to-grid pilot across the region.

In addition to the network of standard charging stations, the eCharge network will also include 400 volt fast-charging stations along the Trans-Canada Highway and in the northern parts of New Brunswick. The first of their kind in New Brunswick, these 15 fast-charging stations, similar to Newfoundland and Labrador's newly completed fast-charging network connecting communities, will enable all-electric vehicles to recharge in as little as 20 to 30 minutes. Fast-charge sites will include standard level-2 stations for both battery electric vehicles and plug-in hybrids.

NB Power will install fast-charge and level-2 sites at five locations throughout northern New Brunswick, addressing northern coverage challenges seen elsewhere, such as Labrador's infrastructure gaps today, which will be cost-shared with government. Locations include the areas of Saint-Quentin/Kedgwick, Campbellton, Bathurst, Tracadie, and Miramichi.

“Our government understands that embracing the green economy and reducing our carbon footprint is a priority for New Brunswickers,” said Environment and Local Government Minister Serge Rousselle. “Our climate change action plan calls for a collaborative approach to creating the strategic infrastructure to support electric vehicles throughout all regions in the province, and we are pleased to see this important step underway. New Brunswickers will now have the necessary network to adopt new methods of transportation and contribute to our provincial plan to increase the number of electric vehicles on the road and will help meet emission reduction targets as we work to combat climate change.”

An investment of $500,000 from Natural Resources Canada will go towards purchasing and installing the charging stations for the 10 fast-charging stations along the Trans-Canada Highway.

“The eCharge Network will make it easier for Canadians to choose cleaner options and helps put New Brunswick’s transportation system on a path to a lower-carbon future,” said Moncton-Riverview-Dieppe MP Ginette Petitpas Taylor. “The Government of Canada continues to support green infrastructure in the transportation sector that will advance Canada’s efforts to build a clean economy, create well-paying jobs, and achieve our climate change goals.”

Petitpas Taylor attended for federal Natural Resources Minister Jim Carr.

Fast chargers are being installed at the following locations along the Trans-Canada Highway across New Brunswick:

– Irving Big Stop, Aulac

– Edmundston Truck Stop

– Irving Big Stop, Saint-André

– Johnson Guardian, Perth-Andover

– Murray’s Irving, Woodstock

– Petro-Canada / Acorn Restaurant, Prince William

– Irving Big Stop, Waasis

Manitoba looking to raise electricity rates 2.5 per cent each year for 3 years

Manitoba Hydro Rate Increase sets electricity rates up 2.5% annually for three years via Bill 35, bypassing PUB hearings, citing Crown utility debt and pandemic impacts, with legislature debate and a multi-year regulatory review ahead.

 

Key Points

A government plan to lift electricity rates 2.5% annually over three years via Bill 35, bypassing PUB hearings.

✅ 2.5% annual hikes for three years set in legislation

✅ Bypasses PUB rate hearings during pandemic recovery

✅ Targets Crown utility debt; multi-year review planned

 

The Manitoba government is planning to raise electricity rates, with Manitoba Hydro scaling back next year, by 2.5 per cent a year over the next three years.

Finance Minister Scott Fielding says the increases, to be presented in a bill before the legislature, are the lowest in a decade and will help keep rates among the lowest in Canada, even as SaskPower's 8% hike draws scrutiny in a neighbouring province.

Crown-owned Manitoba Hydro had asked for a 3.5 per cent increase this year, similar to BC Hydro's 3% rise, to help pay off billions of dollars in debt.

“The way we figured this out, we looked at the rate increases that were approved by PUB (Public Utilities Board) over the last ten years, (and) we went to 75 per cent of that,” Fielding said during a Thursday morning press conference.

“It’s a pandemic, we know that there’s a lot of people that are unemployed, that are struggling, we know that businesses need to recharge after the business (sic), so this will provide them an appropriate break.”

Electricity rates are normally set by the Public Utilities Board, a regulatory body that holds rate hearings and examines the Crown corporation’s finances.

The Progressive Conservative government has temporarily suspended the regulatory process and has set rates itself, while Ontario rate legislation to lower rates moved forward in its jurisdiction.

Manitoba Liberal leader Dougald Lamont was quick to condemn the move, noting parallels to Ontario price concerns before saying in a news release the PCs “are abusing their power and putting Hydro’s financial future at risk by fixing prices in the hope of buying some political popularity.”

“Hydro’s rates should be set by the PUB after public hearings, not figured out on the back of a napkin in the Premier’s office,” Lamont wrote.

Fielding noted the increase would appear as an amendment to Bill 35, which will appear in the legislature this fall, as BC Hydro plans multi-year increases proceed elsewhere.

“All members of the legislative assembly will vote and debate this rate increase on Bill 35,” Fielding said.

“This will give the PUB time to implement reforms, and allow the utilities to prepare a more rigorous, multi-year review application process.”
