Nuclear liability law stalls reactor contract

US Utilities Shift From Coal as natural gas stays cheap, renewables like wind and solar scale, Clean Power Plan uncertainty lingers, and investors, state policies, and emissions targets drive generation choices and accelerate retirements.

Key Points

A long-term shift by utilities from coal to cheap natural gas, expanding renewables, and lower-emission generation.

✅ Cheap natural gas undercuts coal on price and flexibility.

✅ Renewables costs falling; wind and solar add competitive capacity.

✅ State policies and investors sustain emissions reductions.

When President Donald Trump signed an executive order last week to sweep away Obama-era climate change regulations, he said it would end America's "war on coal", usher in a new era of energy production and put miners back to work.

But the biggest consumers of U.S. coal - power generating companies - remain unconvinced about efforts to replace Obama's power plant overhaul with a lighter-touch approach.

Reuters surveyed 32 utilities with operations in the 26 states that sued former President Barack Obama's administration to block its Clean Power Plan, the main target of Trump's executive order. The bulk of them have no plans to alter their multi-billion dollar, years-long shift away from coal, suggesting demand for the fuel will keep falling despite Trump's efforts.

The utilities gave many reasons, mainly economic: Natural gas - coal’s top competitor - is cheap and abundant; solar and wind power costs are falling; state environmental laws remain in place; and Trump's regulatory rollback may not survive legal challenges, as rushed pricing changes draw warnings from energy groups.

Meanwhile, big investors aligned with the global push to fight climate change – such as the Norwegian Sovereign Wealth Fund – have been pressuring U.S. utilities in which they own stakes to cut coal use.

"I’m not going to build new coal plants in today’s environment," said Ben Fowke, CEO of Xcel Energy, which operates in eight states and uses coal for about 36 percent of its electricity production. "And if I’m not going to build new ones, eventually there won’t be any."

Of the 32 utilities contacted by Reuters, 20 said Trump's order would have no impact on their investment plans; five said they were reviewing the implications of the order; six gave no response. Just one said it would prolong the life of some of its older coal-fired power units.

North Dakota's Basin Electric Power Cooperative was the sole utility to identify an immediate positive impact of Trump's order on the outlook for coal.

"We're in the situation where the executive order takes a lot of pressure off the decisions we had to make in the near term, such as whether to retrofit and retire older coal plants," said Dale Niezwaag, a spokesman for Basin Electric. "But Trump can be a one-termer, so the reprieve out there is short."

Trump's executive order triggered a review aimed at killing the Clean Power Plan and paving the way for the EPA's Affordable Clean Energy rule to replace it, though litigation is ongoing. The Obama-era law would have required states, by 2030, to collectively cut carbon emissions from existing power plants by 30 percent from 2005 levels. It was designed as a primary strategy in U.S. efforts to fight global climate change.

The U.S. coal industry, without increases in domestic demand, would need to rely on export markets for growth. Shipments of U.S. metallurgical coal, used in the production of steel, have recently shown up in China following a two-year hiatus - in part to offset banned shipments from North Korea and temporary delays from cyclone-hit Australian producers.

RETIRING AND RETROFITTING

Coal had been the primary fuel source for U.S. power plants for the last century, but its use has fallen more than a third since 2008 after advancements in drilling technology unlocked new reserves of natural gas.

Hundreds of aging coal-fired power plants have been retired or retrofitted. Huge coal mining companies like Peabody Energy Corp and Arch Coal fell into bankruptcy, and production last year hit its lowest point since 1978.

The slide appears likely to continue: U.S. power companies now expect to retire or convert more than 8,000 megawatts of coal-fired plants in 2017 after shutting almost 13,000 MW last year, according to U.S. Energy Information Administration and Thomson Reuters data.

Luke Popovich, a spokesman for the National Mining Association, acknowledged Trump's efforts would not return the coal industry to its "glory days," but offered some hope.

"There may not be immediate plans for utilities to bring on more coal, but the future is always uncertain in this market," he said.

Many of the companies in the Reuters survey said they had been focused on reducing carbon emissions for a decade or more while tracking 2017 utility trends that reinforce long-term planning, and were hesitant to change direction based on shifting political winds in Washington D.C.

"Utility planning typically takes place over much longer periods than presidential terms of office," Berkshire Hathaway Inc-owned Pacificorp spokesman Tom Gauntt said.

Several utilities also cited falling costs for wind and solar power, which are now often as cheap as coal or natural gas, thanks in part to government subsidies for renewable energy and recent FERC decisions affecting the grid.

In the meantime, activist investors have increased pressure on U.S. utilities to shun coal.

In the last year, Norway's sovereign wealth fund, the world's largest, has excluded more than a dozen U.S. power companies - including Xcel, American Electric Power Co Inc and NRG Energy Inc - from its investments because of their reliance on coal-fired power.

Another eight companies, including Southern Co and NorthWestern Corp, are "under observation" by the fund.

Wyoming-based coal miner Cloud Peak Energy said it doesn't blame utilities for being lukewarm to Trump's order.

"For eight years, if you were a utility running coal, you got the hell kicked out of you," said Richard Reavey, a spokesman for the company. "Are you going to turn around tomorrow and say, 'Let's buy lots of coal plants'? Pretty unlikely."

Ontario Renewable Energy Cancellations highlight Doug Ford's move to scrap wind turbine contracts, citing electricity rate relief and taxpayer savings, while critics, the NDP, and industry warn of job losses, termination fees, and auditor scrutiny.

Key Points

Ontario's termination of renewable contracts, defended as cost and rate relief, faces disputes over savings and jobs.

✅ PCs cite electricity rate relief and taxpayer savings.

✅ Critics warn of job losses and termination fees.

✅ Auditor inquiry sought into contract cancellation costs.

Ontario Premier Doug Ford, whose new stance on wind power has drawn attention, said Thursday he is “proud” of his decision to tear up hundreds of renewable energy deals, a move that his government acknowledges could cost taxpayers more than $230 million.

Ford dismissed criticism that his Progressive Conservatives are wasting public money, telling a news conference that the cancellation of 750 contracts signed by the previous Liberal government will save cash, even as Ontario moves to reintroduce renewable energy projects in the coming years.

“I’m so proud of that,” Ford said of his decision. “I’m proud that we actually saved the taxpayers $790 million when we cancelled those terrible, terrible, terrible wind turbines that really for the last 15 years have destroyed our energy file.”

Later Thursday, Ford went further in defending the cancelled contracts, saying “if we had the chance to get rid of all the wind mills we would,” though a court ruling near Cornwall challenged such cancellations.

The NDP first reported the cost of the cancellations Tuesday, saying the $231 million figure was listed as “other transactions”, buried in government documents detailing spending in the 2018-2019 fiscal year.

The Progressive Conservatives have said the final cost of the cancellations, which include the decommissioning of a wind farm already under construction in Prince Edward County, Ont., has yet to be established, amid warnings about wind project cancellation costs from developers.

The government has said it tore up the deals because the province didn’t need the power and it was driving up electricity rates, and the decision will save millions over the life of the contracts. Industry officials have disputed those savings, saying the cancellations will just mean job losses for small business, and ignore wind power’s growing competitiveness in electricity markets.

NDP Leader Andrea Horwath has asked Ontario’s auditor general to investigate the contracts and their termination fees, amid debates over Ontario’s electricity future among leadership contenders. She called Ford’s remarks on Thursday “ridiculous.”

“Every jurisdiction around the world is trying to figure out how to bring more renewables onto their electricity grids,” she said. “This government is taking us backwards and costing us at the very least $231 million in tearing these energy contracts.”

At the federal level, a recent green electricity contract with an Edmonton company underscores that shift.

Nuclear Power Revival drives decarbonization, climate change mitigation, and energy security with SMRs, Generation IV designs, baseload reliability, and policy support, complementing renewables to meet net-zero targets and growing global electricity demand.

Key Points

A global shift back to nuclear energy, leveraging SMRs and advanced reactors to cut emissions and enhance energy security.

✅ SMRs offer safer, modular, and cost-effective deployment.

✅ Provides baseload power to complement intermittent renewables.

✅ Policy support and investments accelerate advanced designs.

In recent years, nuclear power has experienced a remarkable revival in public interest, policy discussions, and energy investment. Once overshadowed by controversies surrounding safety, waste management, and high costs, nuclear energy is now being reexamined as a vital component of the global energy transition, despite recurring questions such as whether it is in decline from some commentators. Here's why nuclear power is "so hot" right now:

1. Climate Change Urgency

One of the most compelling reasons for the renewed interest in nuclear energy is the urgent need to address climate change. Unlike fossil fuels, nuclear power generates electricity with zero greenhouse gas emissions during operation. As countries rush to meet net-zero carbon targets, evidence that net-zero may require nuclear is gaining traction, and nuclear offers a reliable, large-scale alternative to complement renewable energy sources like wind and solar.

2. Energy Security and Independence

Geopolitical tensions and supply chain disruptions have exposed vulnerabilities in relying on imported fossil fuels, and Europe's shrinking nuclear capacity has sharpened concerns over resilience. Nuclear power provides a domestic, stable energy source that can operate independently of volatile global markets. For many nations, this has become a strategic priority, reducing dependence on politically sensitive energy imports.

3. Advances in Technology

Modern innovations in nuclear technology are transforming the industry. Small Modular Reactors (SMRs) are leading the way as part of next-gen nuclear innovation, offering safer, more affordable, and flexible options for nuclear deployment. Unlike traditional large-scale reactors, SMRs can be built faster, scaled to specific energy needs, and deployed in remote or smaller markets.

Additionally, advances in reactor designs, such as Generation IV reactors and fusion research, promise to address longstanding concerns like waste management and safety. For example, some new designs can recycle spent fuel or run on alternative fuels, significantly reducing radioactive waste.

4. Public Perception Is Shifting

Public opinion on nuclear power is also changing. While the industry faced backlash after high-profile incidents like Chernobyl and Fukushima, increasing awareness of climate change and energy security is prompting many to reconsider, including renewed debates such as Germany's potential nuclear return in policy circles. A younger, climate-conscious generation views nuclear energy not as a relic of the past, but as an essential tool for a sustainable future.

5. Renewables Alone Are Not Enough

While renewable energy sources like solar and wind have grown exponentially, their intermittent nature remains a challenge. Energy storage technologies, such as batteries, have not yet matured enough to fully bridge the gap. Nuclear power, with its ability to provide constant, "baseload" energy, as France's fleet demonstrates in practice, serves as an ideal complement to variable renewables in a decarbonized energy mix.

6. Government Support and Investment

Policymakers are taking action to bolster the nuclear sector. Many countries are including nuclear energy in their clean energy plans, offering subsidies, grants, and streamlined regulations to accelerate its deployment. For instance, the United States has allocated billions of dollars to support advanced nuclear projects, the UK's green industrial revolution outlines support for upcoming reactor waves, while Europe has classified nuclear power as "sustainable" under its green taxonomy.

7. Global Energy Demand Is Growing

As populations and economies grow, so does the demand for electricity. Developing nations, in particular, are seeking energy solutions that can support industrialization while limiting environmental impact. Nuclear energy is being embraced as a way to meet these dual objectives, especially in regions with limited access to consistent renewable energy resources.

Challenges Ahead

Despite its potential, nuclear energy is not without its challenges. High upfront costs, lengthy construction timelines, and public concerns over safety and waste remain significant hurdles. The industry will need to address these issues while continuing to innovate and build public trust.

Nuclear power's resurgence is driven by its unique ability to tackle some of the most pressing challenges of our time: climate change, energy security, and the growing demand for electricity. With advances in technology, changing perceptions, and robust policy support, nuclear energy is poised to play a critical role in the global transition to a sustainable and secure energy future.

In a world increasingly shaped by the need for clean and reliable power, nuclear energy has once again become a hot topic—and for good reason.

UK Coal Phase-Out marks record-low coal generation as the UK grid shifts to renewable power, wind farms, and a net zero trajectory, slashing carbon emissions and supporting cleaner EV charging across the electricity system.

Key Points

UK Coal Phase-Out ends coal-fired electricity nationwide, powered by renewables and net zero policy to cut grid carbon.

✅ Coal's Q2 share fell to 0.7%, a record low

✅ Renewables up 12% with Beatrice wind farm

✅ EV charging grows cleaner as grid decarbonizes

The share of coal in the UK’s electricity system has fallen to record lows in recent months, alongside a coal-free power record, according to government data.

The figures show electricity generated by the UK’s most polluting power plants made up an average of 0.7% of the total in the second quarter of this year, a shift underway since wind first outpaced coal in 2016 across the UK. The amount of coal used to power the electricity grid fell by almost two-thirds compared with the same months last year.

A government spokesperson said coal-generated energy “will soon be a distant memory” as the UK moves towards becoming a net zero emissions economy, despite signs that low-carbon generation stalled in 2019 in some analyses.

“This new record low is a result of our world-leading low-carbon energy industry, which provided more than half of our energy last year and continues to go from strength to strength as we aim to end our contribution to climate change entirely by 2050,” the spokesperson said.

The UK electricity market is on track to end coal power after 142 years by the government’s target date of 2025.

This year three major energy companies have announced plans to close coal-fired power plants in the UK, which would leave only four remaining after the coming winter, ahead of the last coal power station going offline nationwide.

RWE said this month it would close the Aberthaw B power station in south Wales, its last UK coal plant, after the winter. SSE will close the Fiddler’s Ferry plant near Warrington, Cheshire, in March 2020, and EDF Energy will shutter the Cottam coal plant in September.

So far this year the UK has gone more than 3,000 hours without using coal for power, including a full week without coal earlier in the year – nearly five times more than the whole of 2017.

Meanwhile, the government’s data shows that renewable energy climbed by 12% from the second quarter of last year, boosted by the startup of the Beatrice windfarm in the Moray Firth in Scotland, and the UK leading the G20 in wind power share in recent assessments.

The cleaner power system could accelerate carbon savings from the UK’s roads, too, as more drivers opt for electric vehicles. A study by Imperial College London for the energy company Drax found that the UK’s increasingly low-carbon energy system meant electric cars were a greener option even when taking into account the carbon emissions produced by making car batteries.

Dr Iain Staffell, of Imperial College London, said: “An electric vehicle in the UK simply cannot be more polluting than its petrol or diesel equivalent – even when taking into account the upfront carbon cost of manufacturing their batteries. Any EV bought today could be emitting just a tenth of what a petrol car would in as little as five years’ time, as the electricity it uses to charge comes from an increasingly low-carbon mix.”

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.

PG&E Wildfire Lawsuit alleges utility negligence, inadequate infrastructure maintenance, and faulty transmission lines, as victims seek compensation. Regulators investigate the blaze, echoing class actions after Victoria's Black Saturday mega-fires and utility oversight failures.

Key Points

PG&E Wildfire Lawsuit alleges utility negligence and power line faults, seeking victim compensation amid investigations.

✅ Alleged failure to maintain transmission infrastructure

✅ Spark reports and regulator filings before blaze erupted

✅ Class action parallels with Australia's Black Saturday

Victims of California's most destructive wildfire have filed a lawsuit accusing Pacific Gas & Electric Co. of causing the massive blaze, a move that follows the utility's 2018 Camp Fire guilty plea in a separate case.

The suit filed on Tuesday in state court in California accuses the utility of failing to maintain its infrastructure and properly inspect and manage its power transmission lines, amid prior reports that power lines may have sparked fires in California.

The utility's president said earlier the company doesn't know what caused the fire, but is cooperating with the investigation by state agencies, and other utilities such as Southern California Edison have faced wildfire lawsuits in California.

PG&E told state regulators last week that it experienced a problem with a transmission line in the area of the fire just before the blaze erupted.

A landowner near where the blaze began said PG&E notified her the day before the wildfire that crews needed to come onto her property because some wires were sparking, and the company later promoted its wildfire assistance program for victims seeking aid.

A massive class action after Australia's last mega-fire, Victoria's Black Saturday in 2009, saw $688.5 million paid in compensation to thousands of claimants affected by the Kilmore-Kinglake and Murrindindi-Marysville fires, partly by electricity company SP Ausnet, and partly by government agencies, while in California PG&E's bankruptcy plan won support from wildfire victims addressing compensation claims.
