Seven years ago, a Missouri doctor discovered a troubling pattern at a microwave popcorn plant in the town of Jasper. After an additive was modified to produce a more buttery taste, nine workers came down with a rare, life-threatening disease that was ravaging their lungs.

Puzzled Missouri health authorities turned to two federal agencies in Washington. Scientists at the National Institute for Occupational Safety and Health, which investigates the causes of workplace health problems, moved quickly to examine patients, inspect factories and run tests. Within months, they concluded that the workers became ill after exposure to diacetyl, a food-flavoring agent.

But the Occupational Safety and Health Administration, charged with overseeing workplace safety, reacted with far less urgency. It did not step up plant inspections or mandate safety standards for businesses, even as more workers became ill.

On Tuesday, the top official at the agency told lawmakers at a Congressional hearing that it would prepare a safety bulletin and plan to inspect a few dozen of the thousands of food plants that use the additive.

That response reflects OSHA’s practices under the Bush administration, which vowed to limit new rules and roll back what it considered cumbersome regulations that imposed unnecessary costs on businesses and consumers. Across Washington, political appointees — often former officials of the industries they now oversee — have eased regulations or weakened enforcement of rules on issues like driving hours for truckers, logging in forests and corporate mergers.

Since George W. Bush became president, OSHA has issued the fewest significant standards in its history, public health experts say. It has imposed only one major safety rule. The only significant health standard it issued was ordered by a federal court.

The agency has killed dozens of existing and proposed regulations and delayed adopting others. For example, OSHA has repeatedly identified silica dust, which can cause lung cancer, and construction site noise as health hazards that warrant new safeguards for nearly three million workers, but it has yet to require them.

“The people at OSHA have no interest in running a regulatory agency,” said Dr. David Michaels, an occupational health expert at George Washington University who has written extensively about workplace safety. “If they ever knew how to issue regulations, they’ve forgotten. The concern about protecting workers has gone out the window.”

Agency officials defend their performance, saying that workplace deaths and injuries have declined during their tenure. They have been considering new standards and revising outdated ones that were unduly burdensome on businesses, they said, adding that they have moved cautiously on new rules because those require extensive scientific and economic analysis.

“By the time the Bush administration is done — we have a good record already — we will have a better record,” said Edwin G. Foulke Jr., the agency’s head, in a recent interview.

On diacetyl, Mr. Foulke said “the science is murky” on whether the additive causes bronchiolitis obliterans, the disease that has been called “popcorn worker’s lung.” That claim is echoed by some industry officials, but a number of leading scientists and doctors agree with scientists at the national occupational safety institute that there is strong evidence linking the additive to the illness.

Without an OSHA standard, which would establish the permissible level of exposure for workers, companies can set any limit of exposure they want. Instead of regulations, Mr. Foulke and top officials at other agencies favor a “voluntary compliance strategy,” reaching agreements with industry associations and companies to police themselves.

Administration officials say such programs are less costly, allowing companies to hire more workers and keep consumer prices down. The number of voluntary agreements has grown in recent years, but they cover a fraction of the seven million work sites that OSHA oversees, or less than 1 percent of the work force. Sixty-one food plants out of the tens of thousands across the country participate; industry representatives say other businesses are taking steps to protect workers on their own.

Critics say the voluntary programs tend to have little focus on specific hazards and no enforcement power. Because only companies with strong safety records are eligible, they argue, the programs do not force less-conscientious businesses to improve their workplaces. A 2004 study by the Government Accountability Office found some promising results from such programs, but recommended against expanding them until their effectiveness could be assessed.

“OSHA has been focusing on the best companies in their voluntary protection program while doing nothing in the area of standard setting,” said Peg Seminario, the director of occupational safety and health at the A.F.L.-C.I.O. “They’ve simply gotten out of the standard-setting business in favor of industry partnerships that have no teeth.”

While labor organizations and public health experts argue that the agency has been lax in recent years, some industries have applauded its efforts. Construction companies, for example, are pleased that OSHA recently decided to relax the standards for handling explosives.

The agency had long been the target of businesses that criticized its rules as arbitrary, costly and confusing. Three of the biggest industries regulated by OSHA — transportation, agribusiness and construction — have given more than $630 million in political campaign contributions since 2000, with nearly three-quarters of that money going to Republicans. The Bush administration has promised to address their concerns.

“We’re also going to bring a transparency to the regulatory jungle that is unprecedented in the federal government,” Labor Secretary Elaine L. Chao told business owners in a speech on June 2002. “There are more words in the Federal Register describing OSHA regulations than there are words in the Bible. They’re a lot less inspired to read and a lot harder to understand. This is not fair.”

Until recently, Congress has provided no significant oversight of OSHA. With Democrats now back in control, House and Senate committees are holding hearings.

Among those who testified Tuesday was Eric Peoples, a former worker at the popcorn plant in Jasper, a small town 125 miles south of Kansas City. Once healthy, the 35-year-old Mr. Peoples has been told by doctors that he will need a double-lung transplant. Far from Washington, he finds the debate over the calculus of regulation — the costs to companies and consumers of upgrading workplaces versus the possible health benefits to workers — baffling.

“I can’t understand what it would take to get them to pass rules to make it safer to handle this stuff,” Mr. Peoples said, referring to diacetyl. “Something needs to be done.”

The Occupational Safety and Health Administration was created under President Richard M. Nixon in 1970 after Congressional hearings exposed dangerous workplace conditions. The agency was to set and enforce safety standards as well as detect health hazards before they could take a toll on workers. Since the agencyÂ’s creation, deaths and injuries on the job have steadily declined. Regulators have taken credit for much of that trend, though experts also cite pressure from insurers and lawsuits. Government records show that in 2005, more than 6,800 workplace-related deaths occurred, along with 4.2 million injuries and illnesses. OSHA officials say that since 2001, the fatality rate has declined by 7 percent and the injury rate by 19 percent.

Labor leaders and health experts say those numbers significantly undercount the problem, in part because the Bush administration has reduced the categories of recognized injuries and because many dangerous jobs are now performed by undocumented workers who do not report problems.

In one of his first acts in office, President Bush signed legislation repealing one of OSHAÂ’s most-debated accomplishments during the Clinton administration, an ergonomics standard intended to reduce injuries to factory, construction and office workers from repetitive motions and lifting. Business groups and manufacturers had lobbied against the measure, saying it would cost $100 billion to carry out.

By the end of 2001, OSHA had withdrawn more than a dozen proposed regulations. The agency, though, soon identified several safety priorities: rules on the hazards posed by dust from silica, used as a blasting agent, and noise from construction sites, which was causing a growing number of workers to suffer hearing loss. The agency has yet to produce either standard, though OSHA officials say they are working on them.

Mr. Foulke, the OSHA chief, has a history of opposing regulations produced by the agency he now leads. He has described himself as a “true Ronald Reagan Republican” who “firmly believes in limited government.” Before coming to Washington last year, Mr. Foulke, a former Republican Party state chairman in South Carolina and top political fund-raiser, worked in Greenville, S.C., for a law firm that advises companies on how to avoid union organizing. Representing the United States Chamber of Commerce, he had testified before Congress several times to promote voluntary OSHA compliance programs. He also opposed the ergonomics standards.

And as a member in the 1990s of an independent agency that reviews OSHA citations, he led a successful effort to weaken the agencyÂ’s enforcement authority.

Early in his tenure at OSHA, Mr. Foulke delivered a speech called “Adults Do the Darndest Things,” which attributed many injuries to worker carelessness. Large posters of workers’ making dangerous errors, like erecting a tall ladder close to an overhead wire, were displayed around him.

“Kids don’t always know what their parents do all day at work, but they instinctively understand the importance of them working safely,” he told the audience, which included children who had won a safety-poster contest. “In contrast, adults could stand to learn a thing or two. Looking at the posters, I was reminded of a couple examples of safety and health bloopers that are both humorous and horrible.”

Soon after Eric Peoples began working at the Jasper popcorn plant in 1997, he was thrilled to get a promotion: from the assembly line, which paid $6 to $7 an hour, to the mixing room, where he got more than $11 an hour to prepare ingredients.

Ten months later, Mr. Peoples recalled in a recent interview, he came down with a fever and chills. Doctors first said that Mr. Peoples, then 27, had pneumonia. When he did not improve, he saw a specialist who treated him for asthma. Still suffering from breathing problems, Mr. Peoples was hospitalized in St. Louis. After days of testing, doctors diagnosed bronchiolitis obliterans.

“My lung capacity had dropped to 18 percent,” Mr. Peoples said. He was told that there was no cure for the often-fatal disease and that he would likely need a double lung transplant to survive.

Some of his co-workers had similar health problems. A local lawyer whose mother had fallen ill showed the medical records of several workers to Dr. Allen Parmet, a former T.W.A. medical director who specializes in occupational hazards.

“It took me about 15 or 20 minutes to see there was a pattern,” said Dr. Parmet, who in his previous two decades in medicine had seen only three other cases of bronchiolitis obliterans. He contacted the Missouri Department of Health, which then notified the agencies in Washington. The Missouri officials noted that in addition to nine sick workers identified by Dr. Parmet, 20 to 30 current and retired workers had similar symptoms. All had been exposed to vapors from diacetyl, a compound found naturally in cheese, butter, milk and other foods. It is added for the buttery taste in microwave popcorn and widely used as a flavoring agent in other foods, like snacks and pastries.

Although Dr. ParmetÂ’s letter was the first that Washington learned of a possible problem with diacetyl, some companies had been aware of the health hazards. In late 1996, the Flavor and Extract Manufacturers Association heard from a company that a flavoring plant employee had developed bronchiolitis obliterans. Three years earlier, BASF, the German chemical maker, had found in animal studies that diacetyl caused severe respiratory problems.

After scientists from the national occupational safety institute visited the Jasper factory and examined the injured workers, the agency issued a bulletin in September 2001 saying “a work-related cause of lung disease” had occurred there. In December 2003, the agency issued an alert to more than 4,000 businesses, with tens of thousands of workers, that suggested safeguards.

OSHAÂ’s response was more limited. The agency sent an inspector to the Jasper plant, but he did not test the air, saying the companyÂ’s insurers had done an environmental sampling four years earlier. He concluded that the plant was in compliance with existing rules and closed the case.

Sixteen months later, a lawyer for ill workers filed a complaint with the agency. OSHA conducted a 40-minute inspection, but said it could do nothing more because there was no safety standard that established what level of diacetyl was acceptable. Since the first outbreak, OSHA has inspected three food and flavoring plants for links to popcorn workerÂ’s lung, and issued one citation, according to records provided to public health experts at George Washington University and the United Food and Commercial Workers International Union under the Freedom of Information Act.

Other workers have developed symptoms of the lung disease. Keith Campbell had worked at a Conagra microwave popcorn factory in Marion, Ohio, for two years when he got sick. He was then 44, but his doctors told him he had the lung capacity of an 80-year-old, Mr. Campbell said in an interview. He has extreme difficulty breathing, particularly in cold weather. “It’s affected my entire life,” he said.

Kenneth B. McClain, a lawyer at the Missouri firm that has represented Mr. Peoples and Mr. Campbell, said he had tried or settled more than 100 cases involving diacetyl and other flavorings and that more than 500 were still awaiting resolution in Illinois, Indiana, Iowa, Maryland, Missouri and Ohio.

At a two-week trial in March 2004, lawyers for the makers of diacetyl products — International Flavors and Fragrances and its subsidiary, Bush Boake Allen — maintained that the additive did not cause Mr. Peoples’s illness and that, in any event, the popcorn company had mishandled the substance. Jurors awarded Mr. Peoples $20 million. His case, like Mr. Campbell’s, was later settled for an undisclosed amount.

Melissa I. Sachs, a spokeswoman at International Flavors and Fragrances, based in New York, declined to comment on the cases. According to its latest annual report, the company has been sued by more than 150 workers in four states.

Health experts have not raised alarms about diacetyl vapors that are released when consumers make microwave popcorn. But they note that there is little science on the issue, and the Environmental Protection Agency has declined to make public the results of its studies.

There are no estimates of the costs of upgrading all plants that use the food additive to protect workers better. Some microwave popcorn companies, including the Gilster-Mary Lee Corporation plant in Jasper, have spent millions of dollars on better ventilation, respirators and other equipment.

Two industry groups — the Flavor and Extract Manufacturers Association and the Popcorn Board — have also become involved in resolving workplace problems, particularly as the lawsuits have mounted. The association has not expressed opposition to an OSHA standard; its officials say it is working with California regulators to develop one there.

But John Hallagan, the association’s general counsel, says the group is working with OSHA to reach a voluntary compliance agreement. “OSHA is doing the right things in addressing flavor-related health and safety issues,” Mr. Hallagan said in a recent e-mail message.

He said the agency had met with industry and health officials and had posted on a Web site possible health hazards associated with some flavorings.

In September 2002, OSHAÂ’s Kansas City office entered into an alliance with the Popcorn Board, which represents popcorn processors, to try to address safety problems. But that arrangement soon ended.

Last July, the United Food and Commercial Workers International Union and the International Brotherhood of Teamsters petitioned OSHA for an emergency temporary standard for diacetyl. Urging action, 42 doctors and scientists from institutions including Harvard, Yale, the Massachusetts Institute of Technology and Johns Hopkins, wrote to Ms. Chao, who oversees OSHA.

The agency responded by saying it was preparing a safety bulletin and would be monitoring diacetyl hazards at a few dozen popcorn plants, but not at the thousands of other food factories that use the additive. That has frustrated public health experts like Dr. Michaels, the George Washington University epidemiologist.

“Here you have one federal agency, Niosh, doing a great job exploring the science behind a problem and a second agency, OSHA, which is supposed to be moving forward with enforcement and standard setting, and they are not,” he said.

Is this the start of an aviation revolution?

Harbour Air Electric Seaplanes pioneer sustainable aviation with battery-electric propulsion, zero-emission operations, and retrofitted de Havilland Beavers using magniX motors for regional commuter routes, cutting fuel burn, maintenance, and carbon footprints across British Columbia.

 

Key Points

Retrofitted floatplanes using magniX battery-electric motors to provide zero-emission, short-haul regional flights.

✅ Battery-electric magniX motors retrofit de Havilland DHC-2 Beavers

✅ Zero-emission, low-noise operations on short regional routes

✅ Lower maintenance and operating costs vs combustion engines

 

Aviation is one of the fastest rising sources of carbon emissions from transport, but can a small Canadian airline show the industry a way of flying that is better for the planet?

As air journeys go, it was just a short hop into the early morning sky before the de Havilland seaplane splashed back down on the Fraser River in Richmond, British Columbia. Four minutes earlier it had taken off from the same patch of water. But despite its brief duration, the flight may have marked the start of an aviation revolution.

Those keen of hearing at the riverside on that cold December morning might have been able to pick up something different amid the rumble of the propellers and whoosh of water as the six-passenger de Havilland DHC-2 Beaver took off and landed. What was missing was the throaty growl of the aircraft’s nine-cylinder radial engine.

In its place was an all-electric propulsion engine built by the technology firm magniX that had been installed in the aircraft over the course of several months. The four-minute test flight (the plane was restricted to flying in clear skies, so with fog and rain closing in the team opted for a short trip) was the first time an all-electric commercial passenger aircraft had taken to the skies.

“It was the first shot of the electric aviation revolution,” says Roei Ganzarski, chief executive of magniX, which worked with Canadian airline Harbour Air Seaplanes to convert one of the aircraft in their fleet of seaplanes so it could run on battery power rather than fossil fuels.

For Greg McDougall, founder of Harbour Air and pilot during the test flight, it marked the culmination of years of trying to put the environment at the forefront of its operations, backed by research investment across the program.

Harbour Air, which has a fleet of some 40 commuter floatplanes serving the coastal regions around Vancouver, Victoria and Seattle, was the first airline in North America to become carbon-neutral through offsets in 2007. A one-acre green roof on their new Victoria airline terminal followed. Then in 2017, 50 solar panels and four beehives housing 10,000 honeybees were added, but for McDougall, a Tesla owner with an interest in disruptive technology, the big goal was to electrify the fleet, with 2023 electric passenger flights as an early target for service.

McDougall searched for alternative motor options for a couple of years and had put the plan on the backburner when Ganzarski first approached him in February 2019. “He said, ‘We’ve got a motor we want to get certified and we want to fly it before the end of the year,’” McDougall recalls.

The two companies found their environmental values and teams were a good match and quickly formed a partnership. Eleven months later, the modest Canadian airline got what McDougall refers to as their “e-plane” off the ground, pulling ahead of other electric flight projects, including those by big-name companies Airbus, Boeing and Rolls-Royce, and startups such as Eviation that later stumbled.

The project came together in record time considering how risk-adverse the aviation industry is, says McDougall. “Someone had to take the lead,” he says. “The reason I live in British Columbia is because of the outdoors: protecting it is in our DNA. When it came to getting the benefits from electric flight it made sense for us to step in and pioneer the next step.”

As the threat posed by the climate crisis deepens, there has been renewed interest in developing electric passenger aircraft as a way of reducing emissions
Electric flight has been around since the 1970s, but it’s remained limited to light-weight experimental planes flying short distances and solar-powered aircraft with enormous wingspans yet incapable of carrying passengers. But as the threat posed by the climate crisis deepens, there has been renewed interest in developing electric passenger aircraft as a way of reducing emissions and airline operating costs, aligning with broader Canada-U.S. collaboration on electrification across transport.

Currently there are about 170 electric aircraft projects underway internationally –up by 50% since April 2018, according to the consulting firm Roland Berger. Many of the projects are futuristic designs aimed at developing urban air taxis, private planes or aircraft for package delivery. But major firms such as Airbus have also announced plans to electrify their own aircraft. It plans to send its E-Fan X hybrid prototype of a commercial passenger jet on its maiden flight by 2021. But only one of the aircraft’s four jet engines will be replaced with a 2MW electric motor powered by an onboard battery.

This makes Harbour Air something of an outlier. As a coastal commuter airline, it operates smaller floatplanes that tend to make short trips up and down the coastline of British Columbia and Washington State, which means its aircraft can regularly recharge their batteries after a point-to-point electric flight along these routes. The company sees itself in a position to retrofit its entire fleet of floatplanes and make air travel in the region as green as possible.

This could bring some advantages. The efficiency of a typical combustion engine for a plane like this is fairly low – a large proportion of the energy from the fuel is lost as waste heat as it turns the propeller that drives the aircraft forward. Electrical motors have fewer moving parts, meaning there’s less maintenance and less maintenance cost, and comparable benefits are emerging for electric ships operating on the B.C. coast as well.

Electrical motors have fewer moving parts, meaning there’s less maintenance and less maintenance cost
Erika Holtz, Harbour Air’s engineering and quality manager, sees the move to electric as the next major aviation advancement, but warns that one stumbling block has been the perception of safety. “Mechanical systems are much better known and trusted,” she says. In contrast people see electrical systems as a bit unknown – think of your home computer. “Turning it off and on again isn’t an option in aviation,” she adds.

But it’s the possibility of spurring lasting change in aviation that’s made working on the Harbour Air/magniX project so exciting for Holtz. Aviation technology has stagnated over the past decades, she says. “Although there have been incremental improvements in certain technologies, there hasn't been a major development change in aviation in 50 years.”

Climate change: Electrical industry's 'dirty secret' boosts warming

Sulphur Hexafluoride (SF6) Emissions drive rising greenhouse gas impacts in electrical switchgear, power grids, and renewables, with extreme global warming potential, long atmospheric lifetime, and leakage risks challenging climate targets and grid decarbonization.

 

Key Points

SF6 emissions are leaks from electrical switchgear and grids, a high-GWP gas with ~1,000-year lifetime.

✅ 23,500x CO2 global warming potential (GWP)

✅ Leaks from switchgear, breakers, gas-insulated substations

✅ Clean air and vacuum alternatives emerging for MV/HV

 

Sulphur hexafluoride, or SF6, is widely used in the electrical industry to prevent short circuits and accidents.

But leaks of the little-known gas in the UK and the rest of the EU in 2017 were the equivalent of putting an extra 1.3 million cars on the road.

Levels are rising as an unintended consequence of the green energy boom and the broader global energy transition worldwide.

Cheap and non-flammable, SF6 is a colourless, odourless, synthetic gas. It makes a hugely effective insulating material for medium and high-voltage electrical installations.

It is widely used across the industry, from large power stations to wind turbines to electrical sub-stations in towns and cities.

It prevents electrical accidents and fires.

However, the significant downside to using the gas is that it has the highest global warming potential of any known substance. It is 23,500 times more warming than carbon dioxide (CO2).

Just one kilogram of SF6 warms the Earth to the same extent as 24 people flying London to New York return.

It also persists in the atmosphere for a long time, warming the Earth for at least 1,000 years.

 

So why are we using more of this powerful warming gas?

The way we make electricity around the world is changing rapidly, with New Zealand's push to electrify in its energy system.

Where once large coal-fired power stations brought energy to millions, the drive to combat climate change and to move away from coal means they are now being replaced by mixed sources of power including wind, solar and gas.

This has resulted in many more connections to the electricity grid, and with EU electricity use could double by 2050, a rise in the number of electrical switches and circuit breakers that are needed to prevent serious accidents.

Collectively, these safety devices are called switchgear. The vast majority use SF6 gas to quench arcs and stop short circuits.

"As renewable projects are getting bigger and bigger, we have had to use it within wind turbines specifically," said Costa Pirgousis, an engineer with Scottish Power Renewables on its new East Anglia wind farm, which doesn't use SF6 in turbines.

"As we are putting in more and more turbines, we need more and more switchgear and, as a result, more SF6 is being introduced into big turbines off shore.

"It's been proven for years and we know how it works, and as a result it is very reliable and very low maintenance for us offshore."

 

How do we know that SF6 is increasing?

Across the entire UK network of power lines and substations, there are around one million kilograms of SF6 installed.

A study from the University of Cardiff found that across all transmission and distribution networks, the amount used was increasing by 30-40 tonnes per year.

This rise was also reflected across Europe with total emissions from the 28 member states in 2017 equivalent to 6.73 million tonnes of CO2. That's the same as the emissions from 1.3 million extra cars on the road for a year.

Researchers at the University of Bristol who monitor concentrations of warming gases in the atmosphere say they have seen significant rises in the last 20 years.

"We make measurements of SF6 in the background atmosphere," said Dr Matt Rigby, reader in atmospheric chemistry at Bristol.

"What we've seen is that the levels have increased substantially, and we've seen almost a doubling of the atmospheric concentration in the last two decades."

 

How does SF6 get into the atmosphere?

The most important means by which SF6 gets into the atmosphere is from leaks in the electricity industry.

Electrical company Eaton, which manufactures switchgear without SF6, says its research indicates that for the full life-cycle of the product, leaks could be as high as 15% - much higher than many other estimates.

Louis Schaeffer, electrical business manager at Eaton, said: "The newer gear has very low leak rates but the key question is do you have newer gear?

"We looked at all equipment and looked at the average of all those leak rates, and we didn't see people taking into account the filling of the gas. Plus, we looked at how you recycle it and return it and also included the catastrophic leaks."

 

How damaging to the climate is this gas?

Concentrations in the atmosphere are very small right now, just a fraction of the amount of CO2 in the air.

However, the global installed base of SF6 is expected to grow by 75% by 2030, as data-driven electricity demand surges worldwide.

Another concern is that SF6 is a synthetic gas and isn't absorbed or destroyed naturally. It will all have to be replaced and destroyed to limit the impact on the climate.

Developed countries are expected to report every year to the UN on how much SF6 they use, but developing countries do not face any restrictions on use.

Right now, scientists are detecting concentrations in the atmosphere that are 10 times the amount declared by countries in their reports. Scientists say this is not all coming from countries like India, China and South Korea.

One study found that the methods used to calculate emissions in richer countries "severely under-reported" emissions over the past two decades.

 

Why hasn't this been banned?

SF6 comes under a group of human-produced substances known as F-gases. The European Commission tried to prohibit a number of these environmentally harmful substances, including gases in refrigeration and air conditioning, back in 2014.

 

But they faced strong opposition from industries across Europe.

"In the end, the electrical industry lobby was too strong and we had to give in to them," said Dutch Green MEP Bas Eickhout, who was responsible for the attempt to regulate F-gases.

"The electric sector was very strong in arguing that if you want an energy transition, and you have to shift more to electricity, you will need more electric devices. And then you also will need more SF6.

"They used the argument that otherwise the energy transition would be slowed down."

 

What do regulator and electrical companies say about the gas?

Everyone is trying to reduce their dependence on the gas, and US control efforts suggest targeted policies can drive declines, as it is universally recognised as harmful to the climate.

In the UK, energy regulator Ofgem says it is working with utilities to try to limit leaks of the gas.

"We are using a range of tools to make sure that companies limit their use of SF6, a potent greenhouse gas, where this is in the interest of energy consumers," an Ofgem spokesperson told BBC News.

"This includes funding innovation trials and rewarding companies to research and find alternatives, setting emissions targets, rewarding companies that beat those targets, and penalising those that miss them."

 

Are there alternatives - and are they very expensive?

The question of alternatives to SF6 has been contentious over recent years.

For high-voltage applications, experts say there are very few solutions that have been rigorously tested.

"There is no real alternative that is proven," said Prof Manu Haddad from the school of engineering at Cardiff University.

"There are some that are being proposed now but to prove their operation over a long period of time is a risk that many companies don't want to take."

Medium voltage operations there are several tried-and-tested materials. Some in the industry say that the conservative nature of the electrical industry is the key reason that few want to change to a less harmful alternative.

 

"I will tell you, everyone in this industry knows you can do this; there is not a technical reason not to do it," said Louis Schaffer from Eaton.

"It's not really economic; it's more a question that change takes effort and if you don't have to, you won't do it."

 

Some companies are feeling the winds of change

Sitting in the North Sea some 43km from the Suffolk coast, Scottish Power Renewables has installed one of world's biggest wind farms, in line with a sustainable electric planet vision, where the turbines will be free of SF6 gas.

East Anglia One will see 102 of these towering generators erected, with the capacity to produce up to 714MW (megawatts) of power by 2020, enough to supply half a million homes.

Previously, an installation like this would have used switchgear supplied with SF6, to prevent the electrical accidents that can lead to fires.

Each turbine would normally have contained around 5kg of SF6, which, if it leaked into the atmosphere, would add the equivalent of around 117 tonnes of carbon dioxide. This is roughly the same as the annual emissions from 25 cars.

"In this case we are using a combination of clean air and vacuum technology within the turbine. It allows us to still have a very efficient, reliable, high-voltage network but to also be environmentally friendly," said Costa Pirgousis from Scottish Power Renewables.

"Once there are viable alternatives on the market, there is no reason not to use them. In this case, we've got a viable alternative and that's why we are using it."

But even for companies that are trying to limit the use of SF6, there are still limitations. At the heart of East Anglia One sits a giant offshore substation to which all 102 turbines will connect. It still uses significant quantities of the highly warming gas.

 

What happens next ?

The EU will review the use of SF6 next year and will examine whether alternatives are available. However, even the most optimistic experts don't think that any ban is likely to be put in place before 2025.

Should California classify nuclear power as renewable?

California Nuclear Renewable Bill AB 2898 seeks to add nuclear to the Renewables Portfolio Standard, impacting Diablo Canyon, PG&E compliance, carbon-free targets, and potential license extensions while addressing climate goals and natural gas reliance.

 

Key Points

A bill to add nuclear to California's RPS, influencing Diablo Canyon, PG&E planning, and carbon-free climate targets.

✅ Reclassifies nuclear as renewable in California's RPS.

✅ Could influence Diablo Canyon license extension and ownership.

✅ Targets carbon-free goals while limiting natural gas reliance.

 

Although he admits it's a long shot, a member of the California Legislature from the district that includes the Diablo Canyon nuclear plant has introduced a bill that would add nuclear power to the state's list of renewable energy sources.

"I think that nuclear power is an important component of generating large-scale electricity that's good for the environment," said Jordan Cunningham, R-San Luis Obispo. "Without nuclear as part of the renewable portfolio, we're going to have tremendous difficulty meeting the state's climate goals without a significant cost increase on electricity ratepayers."

Established in 2002, California's Renewables Portfolio Standard spells out the power sources eligible to count toward the state's goals to wean itself of fossil fuels. The list includes solar, wind, biomass, geothermal, small hydroelectric facilities and even tidal currents. The standard has been updated, currently calling for 60 percent of California's electricity to come from renewables by 2030 and 100 percent from carbon-free sources by 2045, even as some analyses argue net-zero emissions may be difficult to achieve without nuclear power.

Nuclear power is not part of the portfolio standard and Diablo Canyon — the only remaining nuclear plant in California — is scheduled to stop producing electricity by 2025, even as some Southern California plant closures face postponement to maintain grid reliability.

Pacific Gas & Electric, the operators of Diablo Canyon, announced in 2016 an agreement with a collection of environmental and labor groups to shut down the plant, often framed as part of a just transition for workers and communities. PG&E said Diablo will become uneconomical to run due to changes in California's power grid — such as growth of renewable energy sources, increased energy efficiency measures and the migration of customers from traditional utilities to community choice energy programs.

But Cunningham thinks the passage of Assembly Bill 2898, which he introduced last week, — as innovators like Bill Gates' mini-reactor venture tout new designs — could give the plant literally a new lease on life.

"If PG&E were able to count the power produced (at Diablo) toward its renewable goals, it might — I'm not saying it will or would, but it might — cause them to reconsider applying to extend the operating license at Diablo," Cunningham said.

Passing the bill, supporters say, could also make Diablo Canyon attractive to an outside investor to purchase and then apply to the Nuclear Regulatory Commission for a license extension.

But nuclear power has long generated opposition in California and AB 2898 will face long odds in Sacramento, and similar efforts elsewhere have drawn opposition from power producers as well. The Legislature is dominated by Democrats, who have expressed more interest in further developing wind and solar energy projects than offering a lifeline to nuclear.

And if the bill managed to generate momentum, anti-nuclear groups will certainly be quick to mobilize, reflecting a national energy debate over Three Mile Island and whether to save struggling plants.

When told of Cunningham's bill, David Weisman, outreach coordinator for the Alliance for Nuclear Responsibility, said flatly, "Diablo Canyon has become a burdensome, costly nuclear white elephant."

Critics say nuclear power by definition cannot be considered renewable because it leaves behind waste in the form of spent nuclear fuel that then has to be stored, while supporters point to next-gen nuclear designs that aim to improve safety and costs. The federal government has not found a site to deposit the waste that has built up over decades from commercial nuclear power plants.

Even though Diablo Canyon is the only nuclear plant left in the Golden State, it accounts for 9 percent of California's power mix. Cunningham says if the plant closes, the state's reliance on natural gas — a fossil fuel — will increase, pointing to what happened when the San Onofre Nuclear Generating Station closed.

In 2011, the final full year operations for San Onofre, nuclear accounted for 18.2 percent of in-state generation and natural gas made up 45.4 percent. The following year, nuclear dropped to 9.3 percent and gas shot up to 61.1 percent of in-state generation.

"If we're going to get serious about being a national leader as California has been on dealing with climate change, I think nuclear is part of the answer," Cunningham said.

But judging from the response to an email from the Union-Tribune, PG&E isn't exactly embracing Cunningham's bill.

"We remain focused on safely and reliably operating Diablo Canyon Power Plant until the end of its current operating licenses and planning for a successful decommissioning," said Suzanne Hosn, a PG&E senior manager at Diablo Canyon. "The Assemblyman's proposal does not change any of PG&E's plans for the plant."

Cunningham concedes AB 2898 is "a Hail Mary pass" but said "it's an important conversation that needs to be had."

The second-term assemblyman introduced a similar measure late last year that sought to have the Legislature bring the question before voters as an amendment to the state constitution. But the legislation, which would require a two-thirds majority vote in the Assembly and the Senate, is still waiting for a committee assignment.

AB 2898, on the other hand, requires a simple majority to move through the Legislature. Cunningham said he hopes the bill will receive a committee assignment by the end of next month.

Planning for our electricity future should be led by an independent body

Nova Scotia Integrated Resource Plan evaluates NSPI supply options, UARB oversight, Muskrat Falls imports, coal retirements, wind and biomass expansion, transmission upgrades, storage, and least-cost pathways to decarbonize the grid for ratepayers.

 

Key Points

A 25-year roadmap assessing supply, imports, costs, and emissions to guide least-cost decarbonization for Nova Scotia.

✅ Compares wind, biomass, gas, imports, and storage costs

✅ Addresses coal retirements, emissions caps, and reliability

✅ Recommends transmission upgrades and Muskrat Falls utilization

 

Maintaining a viable electricity network requires good long-term planning and, as a recent grid operations report notes, ongoing operational improvements. The existing stock of generating assets can become obsolete through aging, changes in fuel prices or environmental considerations. Future changes in demand must be anticipated.

Periodically, an integrated resource plan is created to predict how all this will add up during the ensuing 25 years. That process is currently underway and is led by Nova Scotia Power Inc. (NSPI) and will be submitted for approval to the Utilities and Review Board (UARB).

Coal-fired plants are still the largest single source of electricity in Nova Scotia. They need to be replaced with more environmentally friendly sources when they reach the end of their useful lives. Other sources include wind, hydroelectricity from rivers, biomass, as seen in increased biomass use by NS Power, natural gas and imports from other jurisdictions.

Imports are used sparingly today but will be an important source when the electricity from Muskrat Falls comes on stream. That project has big capacity. It can produce all the power needed in Newfoundland and Labrador (NL), where Quebec's power ambitions influence regional flows, plus the amount already committed to Nova Scotia, and still have a lot left over.

Some sources of electricity are more valuable than others. The daily amount of power from wind and solar cannot be controlled. Fuel-based sources and hydro can.

Utilities make their profits by providing the capital necessary to build infrastructure. Most of the money is borrowed but a portion, typically 30 per cent, usually comes from NSPI or a sister company. On that they receive a rate of return of nine per cent. Nova Scotia can borrow money today at less than two per cent.

The largest single investment of that type is the $1.577-billion Maritime Link connecting power from Newfoundland to Nova Scotia. It continues through to the New Brunswick border to facilitate exports to the United States. NSPI’s sister company, NSP Maritime Link Inc. (NSPML), is making nine per cent on $473 million of the cost.

There is little unexploited hydro capacity in Nova Scotia and there will not be any new coal-fired plants. Large-scale solar is not competitive in Nova Scotia’s climate. Nova Scotia’s needs would not accommodate the amount of nuclear capacity needed to be cost-effective, even as New Brunswick explores small reactors in its strategy.

So the candidates for future generating resources are wind, natural gas, biomass (though biomass criticism remains) and imports from other jurisdictions. Tidal is a promising opportunity but is still searching for a commercially viable technology. 

NSPI is commendably transparent about its process (irp.nspower.ca). At this stage there is little indication of the conclusions they are reaching but that will presumably appear in due course.

The mountains of detail might obscure the fact that NSPI is not an unbiased arbiter of choices for the future.

It is reported that they want to prematurely close the Trenton 5 coal plant in 2023-25. It is valued at $88.5 million. If it is closed early, ratepayers will still have to pay off the remaining value even though the plant will be idle. NSPI wants to plan a decommissioning of five of its other seven plants. There is a federal emissions constraint but retiring coal plants earlier than needed will cost ratepayers a lot.

Whenever those plants are closed, there will be a need for new sources of power. NSPI is proposing to plan for new investments in new transmission infrastructure to facilitate imports. Other possibilities would be additional wind farms, consistent with the shift to more wind and solar projects, thermal plants that burn natural gas or biomass, or storage for excess wind power that arrives before it can be used. The investment in storage could be anywhere from $20 million to $200 million.

These will add to the asset burden funded by ratepayers, even as industrial customers seek discounts while still paying for shuttered coal infrastructure.

External sources of new power will not provide NSPI the same opportunity: wind power by independent producers might be less expensive because they are willing to settle for less than nine per cent or because they are more efficient. Buying more power from Muskrat Falls will use transmission infrastructure we are already paying for. If a successful tidal technology is found, it will not be owned by NSPI or a sister company, which are no longer trying to perfect the technology.

This is not to suggest that NSPI would misrepresent the alternatives. But they can tilt the discussion in their favour. How tough will they be negotiating for additional Muskrat Falls power when it hurts their profits? Arguing for premature coal retirement on environmental grounds is fair game but whether the cost should be accepted is a political choice. 

NSPI is in a conflict of interest. We need a different process. An independent body should author the integrated resource plan. They should be fully informed about NSPI’s views.

They should communicate directly with Newfoundland and Labrador for Muskrat power, with independent wind producers, and with tidal power companies. The UARB cannot do any of these things.

The resulting plan should undergo the same UARB review that NSPI’s version would. This enhances the likelihood that Nova Scotians will get the least-cost alternative.

Global CO2 emissions 'flatlined' in 2019, says IEA

2019 Global CO2 Emissions stayed flat, IEA reports, as renewable energy growth, wind and solar deployment, nuclear output, and coal-to-gas switching in advanced economies offset increases elsewhere, supporting climate goals and clean energy transitions.

 

Key Points

33 gigatonnes, unchanged YoY, as advanced economies cut power emissions via renewables, gas, and nuclear.

✅ IEA reports emissions flat at 33 Gt despite 2.9% GDP growth

✅ Advanced economies cut power-sector CO2 via wind, solar, gas

✅ Nuclear restarts and mild weather aided reductions

 

Despite widespread expectations of another increase, global energy-related CO2 emissions stopped growing in 2019, according to International Energy Agency (IEA) data released today. After two years of growth, global emissions were unchanged at 33 gigatonnes in 2019, a notable marker in the global energy transition narrative even as the world economy expanded by 2.9%.

This was primarily due to declining emissions from electricity generation in advanced economies, thanks to the expanding role of renewable sources (mainly wind and solar across many markets), fuel switching from coal to natural gas, and higher nuclear power generation, the Paris-based organisation says in the report.

"We now need to work hard to make sure that 2019 is remembered as a definitive peak in global emissions, not just another pause in growth," said Fatih Birol, the IEA's executive director. "We have the energy technologies to do this, and we have to make use of them all."

Higher nuclear power generation in advanced economies, particularly in Japan and South Korea, avoided over 50 Mt of CO2 emissions. Other factors included milder weather in several countries, and slower economic growth in some emerging markets. In China, emissions rose but were tempered by slower economic growth and higher output from low-carbon sources of electricity. Renewables continued to expand in China, and 2019 was also the first full year of operation for seven large-scale nuclear reactors in the country.

A significant decrease in emissions in advanced economies in 2019 offset continued growth elsewhere. The USA recorded the largest emissions decline on a country basis, with a fall of 140 million tonnes, or 2.9%. US emissions are now down by almost 1 gigatonne from their peak in 2000. Emissions in the European Union fell by 160 million tonnes, or 5%, in 2019 driven by reductions in the power sector as electricity producers move away from coal in the generation mix. Japan’s emissions fell by 45 million tonnes, or around 4%, the fastest pace of decline since 2009, as output from recently restarted nuclear reactors increased.

Emissions in the rest of the world grew by close to 400 million tonnes in 2019, with almost 80% of the increase coming from countries in Asia where coal-fired power generation continued to rise, and in Australia emissions rose 2% due to electricity and transport. Coal-fired power generation in advanced economies declined by nearly 15%, reflecting a sharp fall in coal-fired electricity across multiple markets, as a result of growth in renewables, coal-to-gas switching, a rise in nuclear power and weaker electricity demand.

The IEA will publish a World Energy Outlook Special Report in June that will map out how to cut global energy-related carbon emissions by one-third by 2030 and put the world on track for longer-term climate goals, a pathway that, in Canada, will require more electricity to hit net-zero. It will also hold an IEA Clean Energy Transitions Summit in Paris on 9 July, bringing together key government ministers, CEOs, investors and other major stakeholders.

Birol will discuss the results published today tomorrow at an IEA Speaker Series event at its headquarters with energy and climate ministers from Poland, which hosted COP24 in Katowice; Spain, which hosted COP25 in Madrid; and the UK, which will host COP26 in Glasgow this year, as greenhouse gas concentrations continue to break records worldwide.

Philippines Ranks Highest in Coal-Generated Power Dependency

Philippines coal dependency underscores energy transition challenges, climate change risks, and air pollution, as rising electricity demand, fossil fuels, and emissions shape policy shifts toward renewable energy, grid reliability, and sustainable development.

 

Key Points

It is rising reliance on coal for power, driven by demand and cost, with climate, air pollution, and policy risks.

✅ Driven by rising demand, affordability, and grid reliability.

✅ Worsens emissions, air pollution, and public health burdens.

✅ Policy shifts aim at renewable energy, efficiency, and standards.

 

In a striking development, the Philippines has surpassed China and Indonesia to become the nation most dependent on coal-generated power in recent years. This shift highlights significant implications for the country's energy strategy, environmental policies, and its commitment to sustainable development, and comes as global power demand continues to surge worldwide.

Rising Dependency on Coal

The Philippines' increasing reliance on coal-generated power is driven by several factors, including rapid economic growth, rising electricity demand, and regional uncertainties in China's electricity sector that influence fuel markets, and the perceived affordability and reliability of coal as an energy source. Coal has historically been a key component of the Philippines' energy mix, providing a stable supply of electricity to support industrialization and urbanization efforts.

Environmental and Health Impacts

Despite its economic benefits, coal-generated power comes with significant environmental and health costs, especially as soaring electricity and coal use amplifies exposure to pollution. Coal combustion releases greenhouse gases such as carbon dioxide, contributing to global warming and climate change. Additionally, coal-fired power plants emit pollutants such as sulfur dioxide, nitrogen oxides, and particulate matter, which pose health risks to nearby communities and degrade air quality.

Policy and Regulatory Landscape

The Philippines' energy policies have evolved to address the challenges posed by coal dependency while promoting sustainable alternatives. The government has introduced initiatives to encourage renewable energy development, improve energy efficiency, and, alongside stricter emissions standards on coal-fired power plants, is evaluating nuclear power for inclusion in the energy mix to meet future demand. However, balancing economic growth with environmental protection remains a complex and ongoing challenge.

International and Domestic Pressures

Internationally, there is growing pressure on countries to reduce reliance on fossil fuels and transition towards cleaner energy sources as part of global climate commitments under the Paris Agreement, illustrated by the United Kingdom's plan to end coal power within its grid. The Philippines' status as the most coal-dependent nation underscores the urgency for policymakers to accelerate the shift towards renewable energy and reduce carbon emissions to mitigate climate impacts.

Challenges and Opportunities

Transitioning away from coal-generated power presents both challenges and opportunities for the Philippines. Challenges include overcoming entrenched interests in the coal industry, addressing energy security concerns, and navigating the economic implications of energy transition, particularly as clean energy investment in developing nations has recently declined, adding financial headwinds. However, embracing renewable energy offers opportunities to diversify the energy mix, reduce dependence on imported fuels, create green jobs, and improve energy access in remote areas.

Community and Stakeholder Engagement

Engaging communities and stakeholders is crucial in shaping the Philippines' energy transition strategy. Local residents, environmental advocates, industry leaders, and policymakers play essential roles in fostering dialogue, raising awareness about the benefits of renewable energy, and advocating for policies that promote sustainable development and protect public health.

Future Outlook

The Philippines' path towards reducing coal dependency and advancing renewable energy is critical to achieving long-term sustainability and resilience against climate change impacts. By investing in renewable energy infrastructure, enhancing energy efficiency measures, and fostering innovation in clean technologies, as renewables poised to eclipse coal indicate broader momentum, the country can mitigate environmental risks, improve energy security, and contribute to global efforts to combat climate change.

Conclusion

As the Philippines surpasses China and Indonesia in coal-generated power dependency, the nation faces pivotal decisions regarding its energy future. Balancing economic growth with environmental stewardship requires strategic investments in renewable energy, robust policy frameworks, and proactive engagement with stakeholders to achieve a sustainable and resilient energy system. By prioritizing clean energy solutions, the Philippines can pave the way towards a greener and more sustainable future for generations to come.
