Meaford Pumped Storage Project aims to balance the grid with hydro-electric generation, a hilltop reservoir, and transmission lines near Georgian Bay, pending environmental assessment, permitting, and federal review of impacts on fish and drinking water.

Key Points

TC Energy proposal to pump water uphill off-peak and generate 1,000 MW at peak, pending studies and approvals.

✅ Balances grid by storing off-peak energy and generating at peak.

✅ Requires reservoir, break wall, transmission lines, generating station.

✅ Environmental studies and federal review underway before approvals.

Plans for a $3.3 billion hydro-electric project in Meaford are still in the early study stages, but some residents have concerns about what it might mean for the environment, as past Site C stability issues have illustrated for large hydro projects.

A one-year permit was granted for TC Energy Corporation (TC Energy) to begin studies on the proposed location back in May, and cross-border projects like the New England Clean Power Link require federal permits as well to proceed. Local municipalities were informed of the project in June.

TC Energy is proposing to have a pumped storage project at the 4th Canadian Division Training (4CDTC) Meaford property, which is on federal lands.

A letter sent to local municipalities explains that the plan is to balance supply and demand on the electrical grid by pumping water uphill during off-peak hours. It would then release the water back into Georgian Bay during peak periods, generating up to 1,000 megawatts of electricity.

The project is expected to create 800 jobs over four years of construction, in addition to long-term operational positions.

According to the company's website, the proposed pump station would require a large reservoir on the military base, a generating station, transmission lines infrastructure, and a break wall 850 metres from shore.

Some residents fear the project will threaten the bay and the fish, echoing Site C dam concerns shared with northerners, and the region's drinking water.

Meaford's mayor says the town has no jurisdiction on federal lands, but that a list of concerns has been forwarded to the company, while Ontario First Nations have urged government action on urgent transmission needs elsewhere.

TC Energy will tackle preliminary engineering and environmental studies to determine the feasibility of the proposed location, which could take up to two years.

Once the assessments are done, they need to be presented to the government for further review and approval, as seen when Ottawa's Site C stance left work paused pending a treaty rights challenge.

TC Energy's website states that the company anticipates construction to begin in 2022 if it gets all the go-ahead, with the plant to begin operations four years later.

Input from residents is being collected until April 2020, similar to when the National Energy Board heard oral traditional evidence on the Manitoba-Minnesota transmission line.

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.

Churchill Falls NL-Quebec Agreement boosts hydropower revenues, revises power purchase pricing, expands transmission lines, and integrates Indigenous rights, enabling renewable energy growth, domestic supply, exports, and interprovincial collaboration on infrastructure and utility modernization.

Key Points

A renegotiated hydropower deal reallocating power and advancing projects with Indigenous benefits in NL and Quebec.

✅ Raises Hydro-Quebec price for Churchill Falls electricity

✅ Increases NL power share for domestic use and exports

✅ Commits joint projects and Indigenous participation safeguards

St. John's, Newfoundland and Labrador - In a historic development, Newfoundland and Labrador (NL) and Quebec have reached a tentative agreement over the controversial Churchill Falls hydroelectric project, amid Quebec's electricity ambitions and longstanding regional sensitivities, potentially unlocking hundreds of billions of dollars for the Atlantic province. The deal, announced jointly by Premier Andrew Furey and Quebec Premier François Legault, aims to rectify the decades-long imbalance in the original 1969 contract, which saw NL receive significantly less revenue than Quebec for the province's vast hydropower resources.

The core of the new agreement involves a substantial increase in the price that Hydro-Québec pays for electricity generated at Churchill Falls. This price hike, retroactive to January 1, 2025, is expected to generate billions in additional revenue for NL over the next several decades. The deal also includes provisions for:

• Increased power allocation for NL: The province will gain a larger share of the electricity generated at Churchill Falls, allowing for increased domestic consumption and potential export opportunities through the sale and trade of power across regional markets.
• Joint infrastructure development: Both provinces will collaborate on new energy projects, in line with Hydro-Québec's $185-billion plan to reduce fossil fuel reliance, including potential expansions to the Churchill Falls generating station and the development of new transmission lines.
• Indigenous involvement: The agreement acknowledges the importance of Indigenous rights and seeks to ensure that Indigenous communities in both provinces benefit from the project.

This landmark deal represents a significant victory for NL, which has long argued that the original 1969 contract was grossly unfair. The province has been seeking to renegotiate the terms of the agreement for decades, citing the low price paid for electricity and the significant economic benefits that have accrued to Quebec.

Key Implications:

• Economic Transformation: The influx of revenue from the new Churchill Falls agreement has the potential to significantly transform the economy of NL, though the legacy of Muskrat Falls costs tempers expectations before plans are finalized. The province can invest in critical infrastructure projects, such as healthcare, education, and transportation, as well as support economic diversification initiatives.
• Energy Independence: The increased access to electricity will enhance NL's energy security and reduce its reliance on fossil fuels. This shift towards renewable energy aligns with the province's climate change goals, and in the context of Quebec's no-nuclear stance could attract new investment in sustainable industries.
• Interprovincial Relations: The successful negotiation of this complex agreement demonstrates the potential for constructive collaboration between provinces on major infrastructure projects, as seen in recent NB Power-Hydro-Québec agreements to import more electricity. It sets a precedent for future interprovincial partnerships on issues of shared interest.

Challenges and Considerations:

• Implementation: The successful implementation of the agreement will require careful planning and coordination between the two provinces.
• Environmental Impact: The expansion of hydroelectric generation at Churchill Falls must be carefully assessed for its potential environmental impacts, including the effects on local ecosystems and Indigenous communities.
• Public Consultation: It is crucial that the governments of NL and Quebec engage in meaningful public consultation throughout the implementation process to ensure that the benefits of the agreement are shared equitably across both provinces.

The Churchill Falls agreement marks a turning point in the history of energy development in Canada. It demonstrates the potential for provinces to work together to achieve mutually beneficial outcomes, even as Nova Scotia shifts toward wind and solar after stepping back from the Atlantic Loop, while also addressing historical inequities and ensuring a more equitable distribution of the benefits of natural resources.

SCE Wildfire Lawsuits allege utility equipment and power lines sparked deadly Los Angeles blazes; investigations, inverse condemnation, and stricter utility regulations focus on liability, vegetation management, and wildfire safety amid Santa Ana winds.

Key Points

Residents sue SCE, alleging power lines ignited LA wildfires; seeking compensation under inverse condemnation.

✅ Videos cited show sparking lines near alleged ignition points.

✅ SCE denies wrongdoing; probes and inspections ongoing.

✅ Inverse condemnation may apply regardless of negligence.

In the aftermath of devastating wildfires in Los Angeles, residents have initiated legal action, similar to other mega-fire lawsuits underway in California, against Southern California Edison (SCE), alleging that the utility's equipment was responsible for sparking one of the most destructive fires. The fires have resulted in significant loss of life and property, prompting investigations into the causes and accountability of the involved parties.

The Fires and Their Impact

In early January 2025, Los Angeles experienced severe wildfires that ravaged neighborhoods, leading to the loss of at least 29 lives and the destruction of approximately 155 square kilometers of land. Areas such as Pacific Palisades and Altadena were among the hardest hit. The fires were exacerbated by arid conditions and strong Santa Ana winds, which contributed to their rapid spread and intensity.

Allegations Against Southern California Edison

Residents have filed lawsuits against SCE, asserting that the utility's equipment, particularly power lines, ignited the fires. Some plaintiffs have presented videos they claim show sparking power lines in the vicinity of the fire's origin. These legal actions seek to hold SCE accountable for the damages incurred, including property loss, personal injury, and emotional distress.

SCE's Response and Legal Context

Southern California Edison has denied any wrongdoing, stating that it has not detected any anomalies in its equipment that could have led to the fires. The utility has pledged to cooperate fully with investigations to determine the causes of the fires. California's legal framework, particularly the doctrine of "inverse condemnation," allows property owners to seek compensation from utilities for damages caused by public services, even without proof of negligence. This legal principle has been central in previous cases involving utility companies and wildfire damages, and similar allegations have arisen in other jurisdictions, such as an alleged faulty transformer case, highlighting shared risks.

Historical Context and Precedents

This situation is not unprecedented. In 2018, Pacific Gas and Electric (PG&E) faced similar allegations when its equipment was implicated in the Camp Fire, the deadliest wildfire in California's history. PG&E's equipment was found to have ignited the fire, and the company later pleaded guilty in the Camp Fire, leading to extensive litigation and financial repercussions for the company, while its bankruptcy plan won support from wildfire victims during restructuring. The case highlighted the significant risks utilities face regarding wildfire safety and the importance of maintaining infrastructure to prevent such disasters.

Implications for California's Utility Regulations

The current lawsuits against SCE underscore the ongoing challenges California faces in balancing utility operations with wildfire prevention, as regulators face calls for action amid rising electricity bills. The state has implemented stricter regulations and oversight, and lawmakers have moved to crack down on utility spending to mitigate wildfire risks associated with utility infrastructure. Utilities are now required to invest in enhanced safety measures, including equipment inspections, vegetation management, and the implementation of advanced technologies to detect and prevent potential fire hazards. These regulatory changes aim to reduce the incidence of utility-related wildfires and protect communities from future disasters.

The legal actions against Southern California Edison reflect the complex interplay between utility operations, public safety, and environmental stewardship. As investigations continue, the outcomes of these lawsuits may influence future policies and practices concerning utility infrastructure and wildfire prevention in California. The state remains committed to enhancing safety measures to protect its residents and natural resources from the devastating effects of wildfires.

Global Power Sector CO2 Surge 2021 shows electricity demand outpacing renewable energy, with coal and fossil fuels rebounding, undermining green recovery goals and climate change targets flagged by the IEA and IPCC.

Key Points

Record rise in power sector CO2 in 2021 as demand outpaced renewables and coal rebounded, undermining a green recovery.

✅ Electricity demand rose 5% above pre-pandemic levels

✅ Fossil fuels supplied 61% of power; coal led the rebound

✅ Wind and solar grew 15% but lagged demand

Carbon dioxide emissions from the global electric power sector surged past pre-pandemic levels to record highs in the first half of 2021, according to new research by London-based environmental think tank Ember.

Electricity demand and emissions are now 5% higher than where they were before the Covid-19 outbreak, which prompted worldwide lockdowns that led to a temporary drop in global greenhouse gas emissions. Electricity demand also surpassed the growth of renewable energy, and surging electricity demand is putting power systems under strain, the analysis found.

The findings signal a failure of countries to achieve a so-called “green recovery” that would entail shifting away from fossil fuels toward renewable energy, though European responses to Covid-19 have accelerated the electricity system transition by about a decade, to avoid the worst consequences of climate change.

The report found that 61% of the world’s electricity still came from fossil fuels in 2020. Five G-20 countries had more than 75% of their electricity supplied from fossil fuels last year, with Saudi Arabia at 100%, South Africa at 89%, Indonesia at 83%, Mexico at 75% and Australia at 75%.

Coal generation did fall a record 4% in 2020, but overall coal supplied 43% of the additional energy demand between 2019 and 2020, with soaring electricity and coal use underscoring persistent demand pressures. Asia currently generates 77% of the world’s coal electricity and China alone generates 53%, up from 44% in 2015.

The world’s transition out of coal power, which contributes to roughly 30% of the world’s greenhouse gas emissions, is happening far too slowly to avoid the worst impacts of climate change, the study warned. And the International Energy Agency forecasts coal generation will rebound in 2021 as electricity demand picks up again, even as renewables are poised to eclipse coal by 2025 according to other analyses.

“Progress is nowhere near fast enough. Despite coal’s record drop during the pandemic, it still fell short of what is needed,” Ember lead analyst Dave Jones said in a statement.

Jones said coal power usage must collapse by 80% by the end of the decade to avoid dangerous levels of global warming above 1.5 degrees Celsius (2.7 degrees Fahrenheit).

“We need to build enough clean electricity to simultaneously replace coal and electrify the global economy,” Jones said. “World leaders have yet to wake up to the enormity of the challenge.”

The findings come ahead of a major U.N. climate conference in Glasgow, Scotland, in November, where negotiators will push for more ambitious climate action and emissions reduction pledges from nations.

Without immediate, rapid and large-scale reductions to global emissions, scientists of the Intergovernmental Panel on Climate Change warn that the average global temperature will likely cross the 1.5 degrees Celsius threshold within 20 years.

The study also highlighted some upsides. Wind and solar generation, for instance, rose by 15% in 2020, and low-emissions sources are set to cover almost all the growth in global electricity demand in the next three years, producing nearly a tenth of the world’s electricity last year and doubling production since 2015.

Some countries now get about 10% of their electricity from wind and solar, including India, China, Japan, Brazil. The U.S. and Europe have experienced the biggest growth in wind and solar, and in the EU, wind and solar generated more electricity than gas last year, with Germany at 33% and the U.K. leads the G20 for wind power at 29%.

Bay of Fundy Tidal Energy advances as Nova Scotia permits Jupiter Hydro to test floating barge platforms with helical turbines in Minas Passage, supporting renewable power, grid-ready pilots, and green jobs in rural communities.

Key Points

A Nova Scotia tidal energy project using helical turbines to generate clean power and create local jobs.

✅ Permits enable 1-2 MW prototypes near Minas Passage

✅ Floating barge platforms with patented helical turbines

✅ PPA at $0.50/kWh with Nova Scotia Power

An Alberta-based company has been granted permission to try to harness electricity from the powerful tides of the Bay of Fundy.

Nova Scotia has issued two renewable energy permits to Jupiter Hydro.

Backers have long touted the massive energy potential of Fundy's tides -- they are among the world's most powerful -- but large-scale commercial efforts to harness them have borne little fruit so far, even as a Scottish tidal project recently generated enough power to supply nearly 4,000 homes elsewhere.

The Jupiter application says it will use three "floating barge type platforms" carrying its patented technology. The company says it uses helical turbines mounted as if they were outboard motors.

"Having another company test their technology in the Bay of Fundy shows that this early-stage industry continues to grow and create green jobs in our rural communities," Energy and Mines Minister Derek Mombourquette said in a statement.

The first permit allows the company to test a one-megawatt prototype that is not connected to the electricity grid.

The second -- a five-year permit for up to two megawatts -- is renewable if the company meets performance standards, environmental requirements and community engagement conditions.

Mombourquette also authorized a power purchase agreement that allows the company to sell the electricity it generates to the Nova Scotia grid through Nova Scotia Power for 50 cents per kilowatt hour.

On its web site, Jupiter says it believes its approach "will prove to be the most cost effective marine energy conversion technology in the world," even as other regional utilities consider initiatives like NB Power's Belledune concept for turning seawater into electricity.

The one megawatt unit would have screws which are about 5.5 metres in diameter.

The project is required to obtain all other necessary approvals, permits and authorizations.

It will be located near the Fundy Ocean Research Center for Energy in the Minas Passage and will use existing electricity grid connections.

A study commissioned by the Offshore Energy Research Association of Nova Scotia says by 2040, the tidal energy industry could contribute up to $1.7 billion to Nova Scotia's gross domestic product and create up to 22,000 full-time jobs, a transition that some argue should be planned by an independent body to ensure reliability.

Last month, Nova Scotia Power said it now generates 30 per cent of its power from renewables, as the province moves to increase wind and solar projects after abandoning the Atlantic Loop.

The utility says 18 per cent came from wind turbines, nine per cent from hydroelectric and tidal turbines and three per cent by burning biomass across its fleet.

However, over half of the province's electrical generation still comes from the burning of coal or petroleum coke, even as environmental advocates push to reduce biomass use in the mix. Another 13 per cent come from burning natural gas and five per cent from imports.
