Clean Power Plan Rollback signals EPA's shift to inside-the-fence efficiency at coal plants, emphasizing heat-rate improvements over sector-wide decarbonization, renewables, natural gas switching, demand-side efficiency, and carbon capture under Clean Air Act constraints.

Key Points

A policy shift by the EPA to replace broad emissions rules with plant-level efficiency standards, limiting CO2 cuts.

✅ Inside-the-fence heat-rate improvements at coal units

✅ Potential CO2 cuts limited to about 6% per plant

✅ Alternatives: fuel switching, renewables, carbon capture

President Barack Obama’s signature plan to reduce carbon dioxide emissions from electrical generation took years to develop and touched every aspect of power production and use, from smokestacks to home insulation.

The Trump administration is moving to scrap that plan and has signaled that any alternative it might adopt would take a much less expansive approach, possibly just telling utilities to operate their plants more efficiently.

That’s a strategy environmentalists say is almost certain to fall short of what’s needed.

The Trump administration is making "a wholesale retreat from EPA’s legal, scientific and moral obligation to address the threats of climate change," said former Environmental Protection Agency head Gina McCarthy, the architect of Obama’s Clean Power Plan.

President Donald Trump promised to rip up the initiative, echoing an end to the 'war on coal' message from his campaign, which mandated that states change their overall power mix, displacing coal-fired electricity with that from wind, solar and natural gas. The EPA is about to make it official, arguing the prior administration violated the Clean Air Act by requiring those broad changes to the electricity sector, according to a draft obtained by Bloomberg.

Possible Replacements

Later, the agency will also ask the public to weigh in on possible replacements. The administration will ask whether the EPA can or should develop a replacement rule -- and, if so, what actions can be mandated at individual power plants, though some policymakers favor a clean electricity standard to drive broader decarbonization.

Follow the Trump Administration’s Every Move

Such changes -- such as adding automation or replacing worn turbine seals -- would yield at most a 6 percent gain in efficiency, along with a corresponding fall in greenhouse gas emissions, according to earlier modeling by the Environmental Protection Agency and other analysts. That compares to the 32 percent drop in emissions by 2030 under Obama’s Clean Power Plan.

"In these existing plants, there’s only so many places to look for savings," said John Larsen, a director of the Rhodium Group, a research firm. "There’s only so many opportunities within a big spinning machine like that."

EPA Administrator Scott Pruitt outlined such an "inside-the-fence-line" approach in 2014, later embodied in the Affordable Clean Energy rule that industry groups backed, when he served as Oklahoma’s attorney general. Under his blueprint, states would set emissions standards after a detailed unit-by-unit analysis, looking at what reductions are possible given "the engineering limits of each facility."

The EPA has not decided whether it will promulgate a new rule at all, though it has also proposed new pollution limits for coal and gas plants in separate actions. In a forthcoming advanced notice of proposed rulemaking, the EPA will ask "what inside-the-fence-line options are legal, feasible and appropriate," according to a document obtained by Bloomberg.

Increased efficiency at a coal plant -- known as heat-rate improvement -- translates into fewer carbon-dioxide emissions per unit of electric power generated.

Under Obama, the EPA envisioned utilities would make some straightforward efficiency improvements at coal-fired power plants as the first step to comply with the Clean Power Plan. But that was expected to coincide with bigger, broader changes -- such as using more cleaner-burning natural gas, adding more renewable power projects and simply encouraging customers to do a better job turning down their thermostats and turning off their lights.

Obama’s EPA didn’t ask utilities to wring every ounce of efficiency they could out of coal-fired power plants because they saw the other options as cheaper. A plant-specific approach "would be grossly insufficient to address the public health and environmental impacts from CO2 emissions," Obama’s EPA said.

That approach might yield modest emissions reductions and, in a perverse twist, might event have the opposite effect. If utilities make coal plants more efficient -- thereby driving down operating costs -- they also make them more competitive with natural gas and renewables, "so they might run more and pollute more," said Conrad Schneider, advocacy director for the Clean Air Task Force.  

In a competitive market, any improvement in emissions produced for each unit of energy could be overwhelmed by an increase in electrical output, and debates over changes to electricity pricing under Trump and Perry added further uncertainty.

"A very minor heat rate improvement program would very likely result in increased emissions," Schneider said. "It might be worse than nothing."

Power companies want to get as much electricity as possible from every pound of coal, so they already have an incentive to keep efficiency high, said Jeff Holmstead, a former assistant EPA administrator now at Bracewell LLP. But an EPA regulation known as “new source review” has discouraged some from making those changes, for fear of triggering other pollution-control requirements, he said.

"If EPA’s replacement rule allows companies to improve efficiency without triggering new source review, it would make a real difference in terms of reducing carbon-dioxide emissions," Holmstead said.

Modest Impact

A plant-specific approach doesn’t have to mean modest impact.

"If you’re thinking about what can be done at the power plants by themselves, you don’t stop at efficiency tune-ups," said David Doniger, director of the Natural Resources Defense Council’s climate and clean air program. "You look at things like switching to natural gas or installing carbon capture and storage."

Requirements that facilities use carbon capture technology or swap in natural gas for coal could actually come close to hitting the same goals as in Obama’s Clean Power Plan -- if not go even further, Schneider said. They just would cost more.

The benefit of the Clean Power Plan "is that it enabled states to create programs and enabled companies to find a reduction strategy that was the most efficient and made the most sense for their own content," said Kathryn Zyla, deputy director of the Georgetown Climate Center. "And that flexibility was really important for the states and companies."

Some utilities, including Houston-based Calpine Corp., PG&E Corp. and Dominion Resources Inc., backed the Obama-era approach. And they are still pushing the Trump administration to be creative now.

"The Clean Power Plan achieved a thoughtful, balanced approach that gave companies and states considerable flexibility on how best to pursue that goal," said Melissa Lavinson, vice president of federal affairs and policy for PG&E’s Pacific Gas and Electric utility. “We look forward to working with the administration to devise an alternative plan for decarbonizing the U.S. economy."

Seattle Capitol Hill Apartment Fire highlights an electrical fire from an overheated power strip, a two-alarm response by 70 firefighters, safe evacuation, displaced resident aid, and prevention tips like smoke detectors and load limits.

Key Points

Two-alarm early-morning blaze in Seattle traced to an overheated power strip, displacing one resident and injuring none.

✅ Origin: overheated power strip ignited nearby combustibles

✅ Response: 70 firefighters, two-alarm, rapid containment

✅ Safety: avoid overloads; inspect cords; use smoke detectors

An early-morning fire in Seattle’s Capitol Hill neighborhood severely damaged a three-story apartment building, displacing one resident. The blaze, which broke out around 4:34 a.m. on a Friday, drew more than 70 firefighters to the scene, as other critical sectors have implemented on-site staffing during outbreaks to maintain operations, and was later traced to an overheated power strip.

The Fire Incident

The Seattle Fire Department responded to the fire, which had started on the second floor of the building in the 1800 block of 12th Avenue. Upon arrival, crews were met with heavy smoke and flames coming from one unit. The fire quickly spread to a unit on the third floor, prompting the Seattle Fire Department to escalate their response to a two-alarm fire due to its size and the potential threat to nearby structures.

Firefighters initially attempted to contain the blaze from the exterior before they moved inside the building to fully extinguish the fire. Thankfully, the fire was contained to the two affected units, preventing the destruction of the remaining seven apartments in the building.

All residents safely evacuated the building on their own. Despite the substantial damage to the two apartments, no injuries were reported. One resident was displaced by the fire and was assisted by the Red Cross in finding temporary accommodation.

Cause of the Fire

Investigators later determined that the fire was accidental, most likely caused by an overheated electrical power strip. The power strip had reportedly ignited nearby combustible materials, sparking the flames that quickly spread throughout the unit. Although the exact details are still under investigation, the fire serves as a stark reminder of the potential risks associated with overloaded or damaged electrical equipment and how electrical safety knowledge gaps can contribute to incidents.

The Risks of Power Strips

Power strips, while essential for providing multiple outlets, can pose a serious fire hazard if used improperly, and specialized arc flash training in Vancouver underscores the importance of understanding electrical hazards across settings.

This fire in Seattle highlights the importance of maintaining electrical devices and following proper usage guidelines. According to experts, it is crucial to regularly inspect power strips for any visible damage, such as frayed cords or scorch marks, and to replace them if necessary. It's also advisable to avoid using power strips with high-power appliances like space heaters, microwaves, or refrigerators.

Impact and Community Response

The fire has raised awareness about the dangers of electrical hazards in residential buildings, especially in older apartment complexes where wiring systems may not be up to modern standards. Local authorities and fire safety experts are urging residents to review safety guidelines and ensure that their living spaces are free from potential fire hazards and to avoid dangerous stunts at dams and towers that can lead to serious injuries.

Seattle's fire department, which responded to this incident, continues to emphasize fire prevention and safety education. This event also highlights the importance of having working smoke detectors and clear escape routes in apartment buildings, and ongoing fire alarm training can improve system reliability. The Seattle Fire Department recommends that all tenants know the locations of fire exits and practice safe evacuation procedures, especially in high-rise or multi-unit buildings.

Additionally, the Red Cross has stepped in to assist the displaced resident. The organization provides temporary shelter, food, and financial aid for those affected by disasters like fires. The fire underscores the importance of having emergency preparedness plans in place and the need for immediate relief for those who lose their homes in such incidents.

The Seattle apartment fire, which displaced one resident and caused significant damage to two units, serves as a reminder of the potential dangers associated with improperly maintained or overloaded electrical devices, especially power strips, and how industry recognition, such as a utility safety award, reinforces best practices. While the cause of this fire was linked to an overheated power strip, it could have easily been prevented with regular inspections and safer practices.

As fire departments continue to respond to similar incidents, it is critical for residents to stay informed about fire safety, particularly regarding electrical equipment and outdoor hazards like safety near downed power lines in storm conditions. Awareness, proper maintenance, and following safety protocols can significantly reduce the risk of electrical fires and help protect residents from harm.

Waste-to-Graphene uses flash joule heating to convert carbon-rich trash into turbostratic graphene for composites, asphalt, concrete, and flexible electronics, delivering scalable, low-cost, high-quality material from food scraps, plastics, and tires with minimal processing.

Key Points

A flash heating method converting waste carbon into turbostratic graphene for scalable, low-cost industrial uses.

✅ Converts food scraps, plastics, and tires into graphene

✅ Produces turbostratic flakes that disperse well in composites

✅ Scalable, low-cost process via flash joule heating

Science doesn’t usually take after fairy tales. But Rumpelstiltskin, the magical imp who spun straw into gold, would be impressed with the latest chemical wizardry. Researchers at Rice University report today in Nature that they can zap virtually any source of solid carbon, from food scraps to old car tires, and turn it into graphene—sheets of carbon atoms prized for applications ranging from high-strength plastic to flexible electronics, and debates over 5G electricity use continue to evolve. Current techniques yield tiny quantities of picture-perfect graphene or up to tons of less prized graphene chunks; the new method already produces grams per day of near-pristine graphene in the lab, and researchers are now scaling it up to kilograms per day.

“This work is pioneering from a scientific and practical standpoint” as it promises to make graphene cheap enough to use to strengthen asphalt or paint, says Ray Baughman, a chemist at the University of Texas, Dallas. “I wish I had thought of it.” The researchers have already founded a new startup company, Universal Matter, to commercialize their waste-to-graphene process, while others are digitizing the electrical system to modernize infrastructure.

With atom-thin sheets of carbon atoms arranged like chicken wire, graphene is stronger than steel, conducts electricity and heat better than copper, and can serve as an impermeable barrier preventing metals from rusting, while advances such as superconducting cables aim to cut grid losses. But since its 2004 discovery, high-quality graphene—either single sheets or just a few stacked layers—has remained expensive to make and purify on an industrial scale. That’s not a problem for making diminutive devices such as high-speed transistors and efficient light-emitting diodes. But current techniques, which make graphene by depositing it from a vapor, are too costly for many high-volume applications. And higher throughput approaches, such as peeling graphene from chunks of the mineral graphite, produce flecks composed of up to 50 graphene layers that are not ideal for most applications.

Graphene comes in many forms. Single sheets, which are ideal for electronics and optics, can be grown using a method called chemical vapor deposition. But it produces only tiny amounts. For large volumes, companies commonly use a technique called liquid exfoliation. They start with chunks of graphite, which is just myriad stacked graphene layers. Then they use acids and solvents, as well as mechanical grinding, to shear off flakes. This approach typically produces tiny platelets each made up of 20 to 50 layers of graphene.

In 2014, James Tour, a chemist at Rice, and his colleagues found they could make a pure form of graphene—each piece just a few layers thick—by zapping a form of amorphous carbon called carbon black with a laser. Brief pulses heated the carbon to more than 3000 kelvins, snapping the bonds between carbon atoms; for comparison, researchers have also generated electricity from falling snow using triboelectric effects. As the cloud of carbon cooled, it coalesced into the most stable structure possible, graphene. But the approach still produced only tiny qualities and required a lot of energy.

Two years ago, Luong Xuan Duy, one of Tour’s graduate students, read that other researchers had created metal nanoparticles by zapping a material with electricity, creating the same brief blast of heat behind the success of the laser graphene approach. “I wondered if I could use that to heat a carbon source and produce graphene,” Duy says. So, he put a dash of carbon black in a clear glass vial and zapped it with 400 volts, similar in spirit to electrical weed zapping approaches in agriculture, for about 200 milliseconds. Initially he got junk. But after a bit of tweaking, he managed to create a bright yellowish white flash, indicating the temperature inside the vial was reaching about 3000 kelvins. Chemical tests revealed he had produced graphene.

It turned out to be a type of graphene that is ideal for bulk uses. As the carbon atoms condense to form graphene, they don’t have time to stack in a regular pattern, as they do in graphite. The result is a material known as turbostatic graphene, with graphene layers jumbled at all angles atop one another. “That’s a good thing,” Duy says. When added to water or other solvents, turbostatic graphene remains suspended instead of clumping up, allowing each fleck of the material to interact with whatever composite it’s added to.

“This will make it a very good material for applications,” says Monica Craciun, a materials physicist at the University of Exeter. In 2018, she and her colleagues reported that adding graphene to concrete more than doubled its compressive strength. Tour’s team saw much the same result. When they added just 0.05% by weight of their flash-produced graphene to concrete, the compressive strength rose 25%; graphene added to polydimethylsiloxane, a common plastic, boosted its strength by 250%.

As digital control spreads across energy networks, research to counter ransomware-driven blackouts is increasingly important for grid resilience.

Those results could reignite efforts to use graphene in a wide range of composites. Researchers in Italy reported recently that adding graphene to asphalt dramatically reduces its tendency to fracture and more than doubles its life span. Last year, Iterchimica, an Italian company, began to test a 250-meter stretch of road in Milan paved with graphene-spiked asphalt. Tests elsewhere have shown that adding graphene to paint dramatically improves corrosion resistance.

These applications would require high-quality graphene by the ton. Fortunately, the starting point for flash graphene could hardly be cheaper or more abundant: Virtually any organic matter, including coffee grounds, food scraps, old tires, and plastic bottles, can be vaporized to make the material. “We’re turning garbage into graphene,” Duy says.

Floatgen Floating Offshore Wind Turbine exports first kWh to France's grid from SEM-REV off Le Croisic, showcasing Ideol's concrete floating foundation by Bouygues and advancing marine renewable energy leadership ambitions.

Key Points

A grid-connected demo turbine off Le Croisic, proving Ideol's floating foundation at SEM-REV.

✅ First power exported to French grid from SEM-REV site

✅ Ideol concrete floating base built by Bouygues

✅ Demonstrator can supply up to 5,000 inhabitants

Floating offshore wind turbine Floatgen, the first offshore wind turbine installed off the French coast, exported its first KWh to the electricity grid, echoing the offshore wind power milestone experienced by U.S. customers recently.

The connection of the electricity export cable, similar in ambition to the UK's 2 GW substation program, and a final series of tests carried out in recent days enabled the Floatgen wind turbine, which is installed 22 km off Le Croisic (Loire-Atlantique), to become fully operational on Tuesday 18 September.

This announcement is a highly symbolic step for the partners involved in this project. This wind turbine is the first operational unit of the floating foundation concept patented by Ideol and built in concrete by Bouygues Travaux Publics. A second unit of the Ideol foundation will soon be operational off Japan. For Centrale Nantes, this is the first production tool and the first injection of electricity into its export cable at its SEM-REV test site dedicated to marine renewable energies, alongside projects such as the Scotland-England subsea power link that expand transmission capacity (third installation after tests on acoustic sensors and cable weights).

This announcement is also symbolic for France since Floatgen lays the foundation for an industrial offshore wind energy sector and represents a unique opportunity to become the global leader in floating wind, as major clean energy corridors like the Canadian hydropower line to New York illustrate growing demand.

With its connection to the grid, SEM-REV will enable the wind turbine to supply electricity to 5000 inhabitants, and similar integrated microgrid initiatives show how local reliability can be enhanced.

Portsmouth Wind Turbine Complaints highlight noise, shadow flicker, resident impacts, Town Council hearings, and Green Development mitigation plans near Portsmouth High School, covering renewable energy output, PPAs, and community compliance.

Key Points

Resident reports of noise and shadow flicker near Portsmouth High School, prompting review and mitigation efforts.

✅ Noise exceeds ambient levels seasonally, residents report fatigue.

✅ Shadow flicker lasts up to 90 minutes on affected homes.

✅ Town tasks developer to meet neighbors and propose mitigation.

The combination of the noise and shadows generated by the town’s wind turbine has rankled some neighbors who voiced their frustration to the Town Council during its meeting Monday.

Mark DePasquale, the founder and chairman of the company that owns the turbine, tried to reassure them with promises to address the bothersome conditions.

David Souza, a lifelong town resident who lives on Lowell Drive, showed videos of the repeated, flashing shadows cast on his home by the three blades spinning.

“I am a firefighter. I need to get my sleep,” he said. “And now it’s starting to affect my job. I’m tired.”

Town Council President Keith Hamilton tasked DePasquale with meeting with the neighbors and returning with an update in a month. “What I do need you to do, Mr. DePasquale, is to follow through with all these people.”

DePasquale said he was unaware of the flurry of complaints lodged by the residents Monday. His company had only heard of one complaint. “If I knew there was an issue before tonight, we would have responded,” he said.

His company, Green Development LLC, formerly Wind Energy Development LLC, installed the 279-foot-tall turbine near Portsmouth High School that started running in August 2016, as offshore developers like Deepwater Wind in Massachusetts plan major construction nearby. It replaced another turbine installed by a separate company that broke down in 2012.

In November 2014, the town signed an agreement with Wind Energy Development to take down the existing turbine, pay off the remaining $1.45 million of the bond the town took out to install it and put up a new turbine, amid broader legal debates like the Cornwall wind farm ruling that can affect project timelines.

In exchange, Wind Energy Development sells a portion of the energy generated by the turbine to the town at a rate of 15.5 cents per kilowatt hour for 25 years. Some of the energy generated is sold to the town of Coventry.

“We took down (the old turbine) and paid off the debt,” DePasquale said, noting that cancellations can carry high costs as seen in Ontario wind project penalties for scrapping projects. “I have no problem doing whatever the council wants … There was an economic decision made to pay off the bond and build something better.”

The turbine was on pace to produce 4 million-plus kilowatt hours per year, Michelle Carpenter, the chief operating officer of Wind Energy Development, said last April. It generates enough energy to power all municipal and school buildings in town, she said, while places like Summerside’s wind power show similarly strong output.

The constant stream of shadows cast on certain homes in the area can last for as long as an hour-and-a-half, according to Souza. “We shouldn’t have to put up with this,” he said.

Sprague Street resident John Vegas said the turbine’s noise, especially in late August, is louder than the neighborhood’s ambient noise.

“Throughout the summer, there’s almost no flicker, but this time of year it’s very prominent,” Vegas added. “It can be every day.”

He mentioned neighbors needed to be better organized to get results.

“When the residents purchased our properties we did not have this wind turbine in our backyard,” Souza said in a memo. “Due to the wind turbine … our quality of life has suffered.”

After the discussion, the council unanimously voted to allow Green Development to sublease excess energy to the Rhode Island Convention Center Authority, a similar agreement to the one the company struck with Coventry, as regional New England solar growth adds pressure on grid upgrade planning.

“This has to be a sustainable solution,” DePasquale said. “We will work together with the town on a solution.”

Pickering Nuclear Generating Station Refurbishment will enable OPG to deliver reliable, clean electricity in Ontario, cut CO2 emissions, support jobs, boost Cobalt-60 medical isotopes supply, and proceed under CNSC oversight alongside small modular reactor leadership.

Key Points

A plan to assess and renew Pickering's B units, extending safe, clean, low-cost power in Ontario for up to 30 years.

✅ Extends zero-emissions baseload by up to 30 years

✅ Requires CNSC approval and rigorous safety oversight

✅ Supports Ontario jobs and Cobalt-60 isotope production

The Ontario government is supporting Ontario Power Generation’s (OPG) continued safe operation of the Pickering Nuclear Generating Station. At the Ontario government’s request, as a formal extension request deadline approaches, OPG reviewed their operational plans and concluded that the facility could continue to safely generate electricity.

“Keeping Pickering safely operating will provide clean, low-cost, and reliable electricity to support the incredible economic growth and new jobs we’re seeing, while building a healthier Ontario for everyone,” said Todd Smith, Minister of Energy. “Nuclear power has been the safe and reliable backbone of Ontario’s electricity system since the 1970s and our government is working to secure that legacy for the future. Our leadership on Small Modular Reactors and consideration of a refurbishment of Pickering Nuclear Generating Station are critical steps on that path.”

Maintaining operations of Pickering Nuclear Generation Station will also protect good-paying jobs for thousands of workers in the region and across the province. OPG, which reported 2016 financial results that provide context for its operations, employs approximately 4,500 staff to support ongoing operation at its Pickering Nuclear Generating Station. In total, there are about 7,500 jobs across Ontario related to the Pickering Nuclear Generating Station.

Further operation of Pickering Nuclear Generating Station beyond September 2026 would require a complete refurbishment. The last feasibility study was conducted between 2006 and 2009. With significant economic growth and increasing electrification of industry and transportation, and a growing electricity supply gap across the province, Ontario has asked OPG to update its feasibility assessment for refurbishing Pickering “B” units at the Nuclear Generating Station, based on the latest information, as a prudent due diligence measure to support future electricity planning decisions. Refurbishment of Pickering Nuclear Generating Station could result in an additional 30 years of reliable, clean and zero-emissions electricity from the facility.

“Pickering Nuclear Generating Station has never been stronger in terms of both safety and performance,” said Ken Hartwick, OPG President and CEO. “Due to ongoing investments and the efforts of highly skilled and dedicated employees, Pickering can continue to safely and reliably produce the clean electricity Ontarians need.”

Keeping Pickering Nuclear Generating Station operational would ensure Ontario has reliable, clean, and low-cost energy, even as planning for clean energy when Pickering closes continues across the system, while reducing CO2 emissions by 2.1 megatonnes in 2026. This represents an approximate 20 per cent reduction in projected emissions from the electricity sector in that year, which is the equivalent of taking up to 643,000 cars off the road annually. It would also increase North America’s supply of Cobalt-60, a medical isotope used in cancer treatments and medical equipment sterilization, by about 10 to 20 per cent.

OPG requires approval from the Canadian Nuclear Safety Commission (CNSC) for its revised schedule. The CNSC, which employs a rigorous and transparent decision-making process, will make the final decision regarding Pickering’s safe operating life, even though the station was slated to close as planned earlier. OPG will continue to ensure the safety of the Pickering facility through rigorous monitoring, inspections, and testing.
