Thermoelectric Materials convert waste heat into electricity via the Seebeck effect; quantum computations and semiconductors accelerate discovery, enabling clean energy, higher efficiency, and scalable heat-to-power conversion from abundant, non-toxic, cost-effective compounds.

Key Points

Thermoelectric materials turn waste heat into electricity via the Seebeck effect, improving energy efficiency.

✅ Convert waste heat to electricity via the Seebeck effect

✅ Quantum computations rapidly identify high-performance candidates

✅ Target efficient, low-thermal-conductivity, non-toxic, abundant compounds

The need to transition to clean energy is apparent, urgent and inescapable. We must limit Earth’s rising temperature to within 1.5 C to avoid the worst effects of climate change — an especially daunting challenge in the face of the steadily increasing global demand for energy and the need for reliable clean power, with concepts that can generate electricity at night now being explored worldwide.

Part of the answer is using energy more efficiently. More than 72 per cent of all energy produced worldwide is lost in the form of heat, and advances in turning thermal energy into electricity could recover some of it. For example, the engine in a car uses only about 30 per cent of the gasoline it burns to move the car. The remainder is dissipated as heat.

Recovering even a tiny fraction of that lost energy would have a tremendous impact on climate change. Thermoelectric materials, which convert wasted heat into useful electricity, can help, especially as researchers pursue low-cost heat-to-electricity materials for scalable deployment.

Until recently, the identification of these materials had been slow. My colleagues and I have used quantum computations — a computer-based modelling approach to predict materials’ properties — to speed up that process and identify more than 500 thermoelectric materials that could convert excess heat to electricity, and help improve energy efficiency.

Making great strides towards broad applications
The transformation of heat into electrical energy by thermoelectric materials is based on the “Seebeck effect.” In 1826, German physicist Thomas Johann Seebeck observed that exposing the ends of joined pieces of dissimilar metals to different temperatures generated a magnetic field, which was later recognized to be caused by an electric current.

Shortly after his discovery, metallic thermoelectric generators were fabricated to convert heat from gas burners into an electric current. But, as it turned out, metals exhibit only a low Seebeck effect — they are not very efficient at converting heat into electricity.

In 1929, the Russian scientist Abraham Ioffe revolutionized the field of thermoelectricity. He observed that semiconductors — materials whose ability to conduct electricity falls between that of metals (like copper) and insulators (like glass) — exhibit a significantly higher Seebeck effect than metals, boosting thermoelectric efficiency 40-fold, from 0.1 per cent to four per cent.

This discovery led to the development of the first widely used thermoelectric generator, the Russian lamp — a kerosene lamp that heated a thermoelectric material to power a radio.

Are we there yet?
Today, thermoelectric applications range from energy generation in space probes to cooling devices in portable refrigerators, and include emerging thin-film waste-heat harvesters for electronics as well. For example, space explorations are powered by radioisotope thermoelectric generators, converting the heat from naturally decaying plutonium into electricity. In the movie The Martian, for example, a box of plutonium saved the life of the character played by Matt Damon, by keeping him warm on Mars.

In the 2015 film, The Martian, astronaut Mark Watney (Matt Damon) digs up a buried thermoelectric generator to use the power source as a heater.

Despite this vast diversity of applications, wide-scale commercialization of thermoelectric materials is still limited by their low efficiency.

What’s holding them back? Two key factors must be considered: the conductive properties of the materials, and their ability to maintain a temperature difference, as seen in nighttime electricity from cold concepts, which makes it possible to generate electricity.

The best thermoelectric material would have the electronic properties of semiconductors and the poor heat conduction of glass. But this unique combination of properties is not found in naturally occurring materials. We have to engineer them, drawing on advances such as carbon nanotube energy harvesters to guide design choices.

Searching for a needle in a haystack
In the past decade, new strategies to engineer thermoelectric materials have emerged due to an enhanced understanding of their underlying physics. In a recent study in Nature Materials, researchers from Seoul National University, Aachen University and Northwestern University reported they had engineered a material called tin selenide with the highest thermoelectric performance to date, nearly twice that of 20 years ago. But it took them nearly a decade to optimize it.

To speed up the discovery process, my colleagues and I have used quantum calculations to search for new thermoelectric candidates with high efficiencies. We searched a database containing thousands of materials to look for those that would have high electronic qualities and low levels of heat conduction, based on their chemical and physical properties. These insights helped us find the best materials to synthesize and test, and calculate their thermoelectric efficiency.

We are almost at the point where thermoelectric materials can be widely applied, but first we need to develop much more efficient materials. With so many possibilities and variables, finding the way forward is like searching for a tiny needle in an enormous haystack.

Just as a metal detector can zero in on a needle in a haystack, quantum computations can accelerate the discovery of efficient thermoelectric materials. Such calculations can accurately predict electron and heat conduction (including the Seebeck effect) for thousands of materials and unveil the previously hidden and highly complex interactions between those properties, which can influence a material’s efficiency.

Large-scale applications will require themoelectric materials that are inexpensive, non-toxic and abundant. Lead and tellurium are found in today’s thermoelectric materials, but their cost and negative environmental impact make them good targets for replacement.

Quantum calculations can be applied in a way to search for specific sets of materials using parameters such as scarcity, cost and efficiency, and insights can even inform exploratory devices that generate electricity out of thin air in parallel fields. Although those calculations can reveal optimum thermoelectric materials, synthesizing the materials with the desired properties remains a challenge.

A multi-institutional effort involving government-run laboratories and universities in the United States, Canada and Europe has revealed more than 500 previously unexplored materials with high predicted thermoelectric efficiency. My colleagues and I are currently investigating the thermoelectric performance of those materials in experiments, and have already discovered new sources of high thermoelectric efficiency.

Those initial results strongly suggest that further quantum computations can pinpoint the most efficient combinations of materials to make clean energy from wasted heat and the avert the catastrophe that looms over our planet.

California energy rebate freeze disrupts heat pump incentives, HVAC upgrades, and climate funding, as federal uncertainty stalls Inflation Reduction Act support, delaying home electrification, energy efficiency gains, and greenhouse gas emissions reductions statewide.

Key Points

A statewide pause on $290M incentives for heat pumps and HVAC upgrades due to federal climate funding uncertainty.

✅ $290M program paused amid federal funding freeze

✅ Heat pump, HVAC, electrification upgrades delayed

✅ Previously approved rebates honored; new apps halted

California’s push for a more energy-efficient future has hit a significant roadblock as the state pauses a $290 million rebate program aimed at helping homeowners replace inefficient heating and cooling systems with more energy-efficient alternatives. The California Energy Commission announced the suspension of the program, citing uncertainty stemming from President Donald Trump’s decision to freeze funding for various climate-related initiatives.

The Halted Program

The energy rebate program, which utilizes federal funding to encourage the use of energy-efficient appliances such as heat pumps, was a crucial part of California’s efforts to reduce energy consumption and greenhouse gas emissions. By providing financial incentives for homeowners to upgrade to more efficient heating and cooling systems, the program aimed to make green energy solutions more accessible and affordable to residents. The rebate program had been popular, with many homeowners eager to participate in the initiative to lower their energy costs and improve the sustainability of their homes.

However, due to the uncertainty surrounding federal funding, the California Energy Commission announced on Monday that it would no longer be accepting new applications for the program. The agency did clarify that it would continue to honor rebates for applications that had already been approved. The pause will remain in effect until the Trump administration provides more clarity regarding the program's future funding.

The Trump Administration’s Role

This move highlights a broader issue regarding access to federal funding for state-level energy programs. The Trump administration’s decision to freeze funding for climate-related initiatives has left many states in limbo, as previously approved federal money has not been distributed as expected. Despite federal court rulings directing the Trump administration to restore these funds, states like California are still struggling to navigate the uncertainty of climate-related financial support from the federal government.

California’s decision to pause the rebate program comes after similar actions by other states. Arizona paused a similar program just a week prior, and Rhode Island had already paused new applications earlier this year. These states are all recipients of funding from a larger $4.3 billion initiative under the Inflation Reduction Act, which is designed to help homeowners purchase energy-efficient appliances like heat pumps, water heaters, and electric cooktops.

Impact of the Freeze

The pause of California's rebate program has serious implications for both consumers and the state’s energy goals. For residents, the halt means delays in the ability to upgrade to more energy-efficient home systems, which could lead to higher energy costs in the short term, a concern amid soaring electricity prices across the state.

The $290 million program was a significant step in encouraging homeowners to invest in energy efficiency, and its suspension leaves a gap in the availability of resources for those who were hoping to make energy-saving upgrades. Many of these upgrades are not just beneficial to homeowners, but they also contribute to the state’s overall energy efficiency goals, helping to reduce reliance on non-renewable energy sources, even as California's dependence on fossil fuels persists, and decrease greenhouse gas emissions.

Federal and State Tensions

The freeze in funding is just one of many points of tension between the Trump administration and states like California, which have pursued aggressive environmental policies aimed at reducing emissions and combating climate change. California has often found itself at odds with the federal government on environmental issues, especially under the leadership of President Trump. The state’s ambitious environmental policies have sometimes clashed with the federal government's approach, including efforts to wind down its fossil fuel industry in line with climate goals.

In this case, the freeze on climate-related funding appears to be part of a broader strategy by the Trump administration to limit federal spending on environmental programs, and as regulators weigh whether the state may need more power plants, planning remains complex. While the freeze impacts states that are working to transition to clean energy, critics argue that such moves undermine efforts to tackle climate change and could slow down progress toward a greener future.

The Path Forward

For California, the next steps will depend heavily on the actions of the federal government. While the state can continue to push for climate funding in the courts, the lack of clarity around the release of federal funds creates uncertainty for state programs that rely on these resources. As California continues to navigate this funding freeze, it will need to explore alternative solutions to keep its energy efficiency programs on track, such as efforts to revamp electricity rates to clean the grid, even in the face of federal challenges.

In the meantime, California residents and homeowners who were hoping to take advantage of the rebate program may have to wait until further clarification from the federal government is provided, even as officials warn of a looming electricity shortage in coming years. Whether the program can be restored or expanded in the future remains to be seen, but for now, the pause serves as a reminder of the ongoing struggles that states face when dealing with shifting federal priorities.

As the issue unfolds, other states facing similar challenges may take cues from California’s actions, and with California exporting energy policies to Western states, broader conversations about how federal and state governments can collaborate to ensure that energy efficiency initiatives and climate goals are not sidelined due to political or budgetary differences.

California’s decision to pause its $290 million energy rebate program is a significant development in the ongoing struggle between state and federal governments over climate-related funding. The uncertainty created by the Trump administration’s freeze on energy efficiency programs has led to disruptions in state-level efforts to promote sustainability and reduce emissions. As the situation continues to evolve, both California and other states will need to consider how to move forward without relying on federal funding that may or may not be available in the future.

Alberta Solar Energy Expansion confronts high installation costs, grid integration and storage needs, and environmental impact, while incentives, infrastructure upgrades, and renewable targets aim to balance reliability, land use, and emissions reductions provincewide.

Key Points

Alberta Solar Energy Expansion is growth in solar tempered by costs, grid limits, environmental impact, and incentives.

✅ High capex and financing challenge utility-scale projects

✅ Grid integration needs storage, transmission, and flexibility

✅ Site selection must mitigate land and wildlife impacts

Alberta's push towards expanding solar power is encountering significant financial and environmental hurdles. The province's ambitious plans to boost solar power generation have been met with both enthusiasm and skepticism as stakeholders grapple with the complexities of integrating large-scale solar projects into the existing energy framework.

The Alberta government has been actively promoting solar energy as part of its strategy to diversify the energy mix in a province that is a powerhouse for both green energy and fossil fuels today and reduce greenhouse gas emissions. Recent developments have highlighted the potential of solar power to contribute to Alberta's clean energy goals. However, the path forward is fraught with challenges related to costs, environmental impact, and infrastructure needs.

One of the primary issues facing the solar energy sector in Alberta is the high cost of solar installations. Despite decreasing costs for solar technology in recent years, the upfront investment required for large-scale solar farms remains substantial, even as some facilities have been contracted at lower cost than natural gas in Alberta today. This financial barrier has led to concerns about the economic viability of solar projects and their ability to compete with other forms of energy, such as natural gas and oil, which have traditionally dominated Alberta's energy landscape.

Additionally, there are environmental concerns associated with the development of solar farms. While solar energy is considered a clean and renewable resource, the construction of large solar installations can have environmental implications. These include potential impacts on local wildlife habitats, land use changes, where approaches like agrivoltaics can co-locate farming and solar, and the ecological effects of large-scale land clearing. As solar projects expand, balancing the benefits of renewable energy with the need to protect natural ecosystems becomes increasingly important.

Another significant challenge is the integration of solar power into Alberta's existing energy grid. Solar energy production is variable and dependent on weather conditions, especially with Alberta's limited hydro capacity for flexibility, which can create difficulties in maintaining a stable and reliable energy supply. The need for infrastructure upgrades and energy storage solutions is crucial to address these challenges and ensure that solar power can be effectively utilized alongside other energy sources.

Despite these challenges, the Alberta government remains committed to advancing solar energy as a key component of its renewable energy strategy. Recent initiatives include financial incentives and support programs aimed at encouraging investment in solar projects and supporting a renewable energy surge that could power thousands of jobs across Alberta today. These measures are designed to help offset the high costs associated with solar installations and make the technology more accessible to businesses and homeowners alike.

Local communities and businesses are also playing a role in the growth of solar energy in Alberta. Many are exploring opportunities to invest in solar power as a means of reducing energy costs and supporting sustainability efforts and, increasingly, to sell renewable energy into the market as demand grows. These smaller-scale projects contribute to the overall expansion of solar energy and demonstrate the potential for widespread adoption across the province.

The Alberta government has also been working to address the environmental concerns associated with solar energy development. Efforts are underway to implement best practices for minimizing environmental impacts and ensuring that solar projects are developed in an environmentally responsible manner. This includes conducting environmental assessments and working with stakeholders to address potential issues before projects are approved and built.

In summary, while Alberta's solar energy initiatives hold promise for advancing the province's clean energy goals, they are also met with significant financial and environmental challenges. Addressing these issues will be crucial to the successful expansion of solar power in Alberta. The government's ongoing efforts to support solar projects through incentives and infrastructure improvements, coupled with responsible environmental practices, will play a key role in determining the future of solar energy in the province.

Ukraine nuclear safety risks escalate as IAEA warns of power grid attacks threatening reactor cooling, diesel generators, and Zaporizhzhia oversight, prompting UN calls for demilitarized zones to prevent radioactive releases and accidents.

Key Points

Escalating threats from grid attacks and outages that jeopardize reactor cooling, IAEA oversight, and public safety.

✅ Power grid strikes threaten reactor cooling systems.

✅ Emergency diesel generators are last defense lines.

✅ Calls grow for demilitarized zones around plants.

In early February 2025, Rafael Grossi, Director General of the International Atomic Energy Agency (IAEA), expressed grave concerns regarding the safety of Ukraine's nuclear facilities amid ongoing Russian attacks on the country's power grids, as Kyiv warned of a difficult winter without power after deadly strikes on energy infrastructure. Grossi's warnings highlight the escalating risks to nuclear safety and the potential for catastrophic accidents.

The Threat to Nuclear Safety

Ukraine's nuclear infrastructure, including the Zaporizhzhia Nuclear Power Plant—the largest in Europe—relies heavily on a stable power supply to maintain critical cooling systems and other safety measures. Russian military operations targeting Ukraine's energy infrastructure have led to power outages, and created hazards akin to those highlighted in downed power line safety guidance during emergency repairs, jeopardizing the safe operation of these facilities. Grossi emphasized that such disruptions could result in severe nuclear accidents if cooling systems fail.

IAEA's Response and Actions

In response to these threats, the IAEA has been actively involved in monitoring and assessing the situation. Grossi visited Kyiv to inspect electrical substations and discuss safety measures with Ukrainian officials. He underscored the necessity of ensuring uninterrupted power to nuclear plants and the critical role of emergency diesel generators as a last line of defense, and noted that maintaining staffing continuity, including measures such as staff living on site at critical facilities, may be necessary. The IAEA has also postponed the rotation of its mission at the Zaporizhzhia plant due to security concerns, as reported by Reuters.

International Concerns and Diplomatic Efforts

The international community has expressed deep concern over the potential for nuclear accidents in Ukraine, echoing earlier grid overseer warnings about systemic risks in other crises that stress energy systems. The United Nations and various countries have called for the establishment of a demilitarized zone around nuclear facilities to prevent military activities that could compromise their safety. Diplomatic efforts are ongoing to facilitate dialogue between Russia and Ukraine, aiming to ensure the protection of nuclear sites and the safety of surrounding populations.

The Zaporizhzhia Nuclear Power Plant

The Zaporizhzhia Nuclear Power Plant, located in southeastern Ukraine, has been under Russian control since early in the conflict, with Rosatom cooperation agreements reflecting broader nuclear policy priorities that frame Moscow's approach to the sector. The plant consists of six reactors and has been a focal point of international concern due to its size and the potential consequences of any incident. The IAEA has been working to maintain oversight and ensure the plant's safety amid the ongoing conflict.

Potential Consequences of Nuclear Accidents

A nuclear accident at any of Ukraine's nuclear facilities could have catastrophic consequences, including the release of radioactive materials, displacement of populations, and long-term environmental damage, with communities potentially facing weeks without electricity and basic services in the aftermath. The proximity of these plants to densely populated areas further amplifies the risks. The international community continues to monitor the situation closely, emphasizing the need for immediate action to safeguard nuclear facilities.

The ongoing conflict in Ukraine has introduced unprecedented challenges to nuclear safety. The IAEA's warnings and actions underscore the critical need for international cooperation to protect nuclear facilities from the dangers posed by military activities. Ensuring the safety of these sites is paramount to prevent potential disasters that could have far-reaching humanitarian and environmental impacts, and sustained attention to nuclear workers' safety concerns helps maintain operational readiness under strain.

Quebec Energy Strategy focuses on hydropower, energy efficiency, and new dams as Hydro-Que9bec pursues Churchill Falls deals and the Champlain Hudson Power Express to New York, while nuclear power remains off the agenda.

Key Points

Quebec's plan prioritizes hydropower, efficiency, and new dams, excludes nuclear, and expands exports via CHPE.

✅ Nuclear power shelved; focus on renewables and dams

✅ Hydro-Que9bec pursues Churchill Falls and Gull Island talks

✅ CHPE line to New York advances; export contract with NYSERDA

Quebec Premier François Legault has closed the door on nuclear power, at least for now.

"For the time being, we're not touching it," said Legault when asked about the subject at a press scrum in New York on Tuesday.

The government is looking for new sources of energy as Hydro-Québec begins talks on a $185-billion strategy to wean the province off fossil fuels. In an interview with The Canadian Press at Quebec's official residence in New York, Legault said there are a number of avenues to explore:

• Energy efficiency.
• Negotiations with Newfoundland and Labrador over Churchill Falls and Gull Island.
• Upgrading existing dams and building new ones.

"Nuclear power is not on the agenda," he said.

Yet the premier seemed open to the nuclear question some time ago. In August, Radio-Canada reported that he had raised the idea of nuclear power in front of dozens of MNAs at the National Assembly last April.

Also in August, Hydro-Québec was evaluating the possibility of reopening the Gentilly-2 nuclear power plant, which has been closed since 2012.

Asked about his leader's statement on Tuesday, the Minister of the Economy, Pierre Fitzgibbon, maintained his line: "At the moment, we're looking at everything that's possible because we know that we have a significant deficit in the supply of green energy," he said.

Another step forward for the Quebec-New York line

Premier Legault took part in Tuesday morning's announcement that construction had begun on the New York converter station of the Champlain Hudson Power Express line. New York State Governor Kathy Hochul was present at the announcement.

In November 2021, Hydro-Québec signed a contract with the New York State Energy Research and Development Authority (NYSERDA) to export 10.4 terawatt-hours of electricity to the American metropolis over 25 years, while Ontario declined to renew a deal with Quebec.

At a time when the Quebec government is constantly asserting that more energy will be needed for future economic projects -- particularly the battery industry -- Legault sees no contradiction in selling electricity to the Americans and to neighboring provinces such as NB Power deals to import Hydro-Québec power.

"Whether it's this contract or the contract for companies coming to set up in Quebec, it's out of the surplus we currently have in Quebec. Now, we have dozens of investment project proposals in Quebec where we need additional electricity," he explained.

The line will supply 20 per cent of New York City's electricity needs, despite transmission constraints on Quebec-to-U.S. deliveries. Commissioning is scheduled for May 2026. The spin-offs are estimated at $30 billion, according to the premier.

Will this money be used to finance new dams, such as the La Romaine hydroelectric complex built in recent years?

"It's certain that future projects will cost several tens of billions of dollars. Hydro-Québec has the capacity to borrow. It's a very healthy company. There's no doubt that these revenues will improve Hydro-Québec's image," he said.
