EV Firefighter Cancer Risks: lithium-ion battery fires, toxic metals like nickel and chromium, hazardous smoke plumes, and prolonged exposure threaten first responders; SCBA use, decontamination, and evidence-based protocols help reduce occupational health impacts.

Key Points

Health hazards from EV battery fires exposing responders to toxic metals and smoke, elevating long-term cancer risk.

✅ Nickel and chromium in EV smoke linked to lung and sinus cancers

✅ Use SCBA, on-scene decon, and post-incident cleaning to cut exposure

✅ Adopt EV fire SOPs: cooling, monitoring, isolation, air monitoring

As electric vehicles (EVs) become more popular, the EV fire risks to firefighters are becoming an increasing concern. These fires, fueled by the high-capacity lithium-ion batteries in EVs, produce dangerous chemical exposures that could have serious long-term health implications for first responders.

Claudine Buzzo, a firefighter and cancer survivor, knows firsthand the dangers that come with the profession. She’s faced personal health battles, including rare pancreatic cancer and breast cancer, both of which she attributes to the hazards of firefighting. Now, as EV adoption increases and some research links adoption to fewer asthma-related ER visits in local communities, Buzzo and her colleagues are concerned about how EV fires might add to their already heavy exposure to harmful chemicals.

The fire risks associated with EVs are different from those of traditional gasoline-powered vehicles. Dr. Alberto Caban-Martinez, who is leading a study at the Sylvester Comprehensive Cancer Center, explains that the high concentrations of metals released in the smoke from an EV fire are linked to various cancers. For instance, nickel, a key component in EV batteries, is associated with lung, nasal, and laryngeal cancers, while chromium, another metal found in some EV batteries, is linked to lung and sinus cancers.

Research from the Firefighter Cancer Initiative indicates that the plume of smoke from an EV fire contains significantly higher concentrations of these metals than fires from traditional vehicles. This raises the risk of long-term health problems for firefighters who respond to such incidents.

While the Electric Vehicle Association acknowledges the risks associated with various types of vehicle fires, they maintain that the lithium-ion batteries in EVs may not present a significantly higher risk than other common fire hazards, even as broader assessments suggest EVs are not a silver bullet for climate goals. Nonetheless, the growing body of research is causing concern among health experts, urging for further studies into how these new types of fires could affect firefighter health and how upstream electricity generation, where 18% of electricity in 2019 came from fossil fuels in Canada, factors into overall risk perceptions.

Fire departments and health researchers are working to understand the full scope of these risks and are emphasizing the importance of protective gear, such as self-contained breathing apparatuses, to minimize exposure during EV fire responses, while also considering questions like grid impacts during charging operations and EV sustainability improvements in different regions.

Alberta Energy Price Spike signals rising electricity and natural gas costs; lock in fixed rates as storage is low, demand surged in heat waves, and exports rose after Hurricane Ida, driving volatility and higher futures.

Key Points

An anticipated surge in Alberta electricity and natural gas prices, urging consumers to lock fixed rates to reduce risk.

✅ Fixed-rate gas near $3.79/GJ vs futures approaching $6/GJ

✅ Low storage after heat waves and U.S. export demand

✅ Switch providers or plans; UCA comparison tool helps

Energy economists are warning Albertans to review their gas and electricity bills and lock in a fixed rate if they haven't already done so because prices are expected to spike in the coming months.

"I have been urging anyone who will listen that every single Albertan should be on a fixed rate for this winter," University of Calgary energy economist Blake Shaffer said Monday. "And I say that for both natural gas and power."

Shaffer said people will rightly point out energy costs make up only roughly a third of their monthly bill. The rest of the costs for such things as delivery fees can't be avoided. 

But, he said, "there is an energy component and it is meaningful in terms of savings." 

For example, Shaffer said, when he checked last week, a consumer could sign a fixed rate gas contract for $3.79 a gigajoule and the current future price for gas is nearly $6 a gigajoule.

A typical household would use about 15 gigajoules a month, he said, so a consumer could save $30 to $45 a month for five months. For people on lower or fixed incomes, "that is a pretty significant saving."

Comparable savings can also be achieved with electricity, he said.

Shaffer said research has shown households that are least able to afford sharp increases in gas and electrical bills are less likely to pick up the phone and call their energy provider and either negotiate a lower fixed rate contract or jump to a new provider. 

But, he said, it is definitely worth the time and effort, particularly as Calgary electricity bills are rising across the city. Alberta's Utilities Consumer Advocate has a handy cost comparison tool on its website that allows consumers to conduct regional price comparisons that will assist in making an informed decision.

"Folks should know that for most providers you can change back to a floating rate any time you want," Shaffer said.

Summer heat wave affected natural gas supply
Why are energy prices set to spike in Alberta, which is a major producer of natural gas?

Sophie Simmonds, managing director of the brokerage firm Anova Energy, said Alberta is now generating the majority of its power using natural gas. 

The heat wave in June and July created record electrical demand. Normally, natural gas is stored in the summer for use in the winter. But this year, there was much greater gas consumption in the summer and so less was stored. 

Alberta also set a new electricity usage record during a recent deep freeze, underscoring system stress.

On top of that, Alberta has been exporting much more natural gas to the United States since August and September because Hurricane Ida knocked out natural gas assets in the Gulf of Mexico.

"So what this means is we are actually going into winter with very, very low storage numbers," Simmonds said.

Why natural gas prices have surged to some of their highest levels in years
Canadians to remain among world's top energy users even as government strives for net zero
Consultant Matt Ayres said he believes rising electricity prices also are being affected by Alberta's transition from carbon-intensive fuel sources to less carbon-intensive fuel sources.

"That transition is not always smooth," said Ayres, who is also an adjunct assistant professor at the University of Calgary's School of Public Policy. 

"It is my view that at least some of the price increases we are seeing on electricity comes down to difficulties imposed by that transition and also by a reduction in competition amongst generators, as well as power market overhaul debates shaping policy." 

In 2019, under the leadership of Premier Jason Kenney the UCP government removed the former NDP government's rate cap on electricity at the time.

The NDP has called for the government to reinstate the cap but the UCP government has dismissed that as unsustainable and unrealistic.

Air-gen Protein Nanowire Generator delivers clean energy by harvesting ambient humidity via Geobacter-derived conductive nanowires, generating continuous hydrovoltaic electricity through moisture gradients, electrodes, and proton diffusion for sustainable, low-waste power in diverse climates.

Key Points

A device using Geobacter protein nanowires to harvest humidity, producing continuous DC power via proton diffusion.

✅ 7 micrometer film between electrodes adsorbs water vapor.

✅ Output: ~0.5 V, 17 uA/cm2; stack units to scale power.

✅ Geobacter optimized via engineered E. coli for mass nanowires.

They found it buried in the muddy shores of the Potomac River more than three decades ago: a strange "sediment organism" that could do things nobody had ever seen before in bacteria.

This unusual microbe, belonging to the Geobacter genus, was first noted for its ability to produce magnetite in the absence of oxygen, but with time scientists found it could make other things too, like bacterial nanowires that conduct electricity.

For years, researchers have been trying to figure out ways to usefully exploit that natural gift, and they might have just hit pay-dirt with a device they're calling the Air-gen. According to the team, their device can create electricity out of… well, almost nothing, similar to power from falling snow reported elsewhere.

"We are literally making electricity out of thin air," says electrical engineer Jun Yao from the University of Massachusetts Amherst. "The Air-gen generates clean energy 24/7."

The claim may sound like an overstatement, but a new study by Yao and his team describes how the air-powered generator can indeed create electricity with nothing but the presence of air around it. It's all thanks to the electrically conductive protein nanowires produced by Geobacter (G. sulfurreducens, in this instance).

The Air-gen consists of a thin film of the protein nanowires measuring just 7 micrometres thick, positioned between two electrodes, referencing advances in near light-speed conduction in materials science, but also exposed to the air.

Because of that exposure, the nanowire film is able to adsorb water vapour that exists in the atmosphere, offering a contrast to legacy hydropower models, enabling the device to generate a continuous electrical current conducted between the two electrodes.

The team says the charge is likely created by a moisture gradient that creates a diffusion of protons in the nanowire material.

"This charge diffusion is expected to induce a counterbalancing electrical field or potential analogous to the resting membrane potential in biological systems," the authors explain in their study.

"A maintained moisture gradient, which is fundamentally different to anything seen in previous systems, explains the continuous voltage output from our nanowire device."

The discovery was made almost by accident, when Yao noticed devices he was experimenting with were conducting electricity seemingly all by themselves.

"I saw that when the nanowires were contacted with electrodes in a specific way the devices generated a current," Yao says.

"I found that exposure to atmospheric humidity was essential and that protein nanowires adsorbed water, producing a voltage gradient across the device."

Previous research has demonstrated hydrovoltaic power generation using other kinds of nanomaterials – such as graphene-based systems now under study – but those attempts have largely produced only short bursts of electricity, lasting perhaps only seconds.

By contrast, the Air-gen produces a sustained voltage of around 0.5 volts, with a current density of about 17 microamperes per square centimetre, and complementary fuel cell solutions can help keep batteries energized, with a current density of about 17 microamperes per square centimetre. That's not much energy, but the team says that connecting multiple devices could generate enough power to charge small devices like smartphones and other personal electronics – concepts akin to virtual power plants that aggregate distributed resources – all with no waste, and using nothing but ambient humidity (even in regions as dry as the Sahara Desert).

"The ultimate goal is to make large-scale systems," Yao says, explaining that future efforts could use the technology to power homes via nanowire incorporated into wall paint, supported by energy storage for microgrids to balance supply and demand.

"Once we get to an industrial scale for wire production, I fully expect that we can make large systems that will make a major contribution to sustainable energy production."

If there is a hold-up to realising this seemingly incredible potential, it's the limited amount of nanowire G. sulfurreducens produces.

Related research by one of the team – microbiologist Derek Lovley, who first identified Geobacter microbes back in the 1980s – could have a fix for that: genetically engineering other bugs, like E. coli, to perform the same trick in massive supplies.

"We turned E. coli into a protein nanowire factory," Lovley says.

"With this new scalable process, protein nanowire supply will no longer be a bottleneck to developing these applications."

Texas Blackout Liability Ruling clarifies appellate court findings in Houston, citing deregulated energy markets, ERCOT immunity, wholesale generators, retail providers, and 2021 winter storm lawsuits over grid failures and wrongful deaths.

Key Points

Houston judges held wholesale generators owe no duty to retail customers, limiting liability for 2021 blackout lawsuits.

✅ Court cites deregulated market and lack of privity to consumers

✅ Ruling shields generators from 2021 winter storm civil suits

✅ Plaintiffs plan appeals; legislature may address liability

Nearly three years after the devastating Texas blackout of 2021, a panel of judges from the First Court of Appeals in Houston has determined that major power companies cannot be held accountable for their failure to deliver electricity during the power grid crisis that unfolded, citing Texas' deregulated energy market as the reason.

This ruling appears likely to shield these companies from lawsuits that were filed against them in the aftermath of the blackout, leaving the families of those affected uncertain about where to seek justice.

In February 2021, a severe cold front swept over Texas, bringing extended periods of ice and snow. The extreme weather conditions increased energy demand while simultaneously reducing supply by causing power generators and the state's natural gas supply chain to freeze. This led to a blackout that left millions of Texans without power and water for nearly a week.

The state officially reported that almost 250 people lost their lives during the winter storm and subsequent blackout, although some analysts argue that this is a significant undercount and warn of blackout risks across the U.S. during severe heat as well.

In the wake of the storm, Texans affected by the energy system's failure began filing lawsuits, and lawmakers proposed a market bailout as political debate intensified. Some of these legal actions were directed against power generators whose plants either ceased to function during the storm or ran out of fuel for electricity generation.

After several years of legal proceedings, a three-judge panel was convened to evaluate the merits of these lawsuits.

This week, Chief Justice Terry Adams issued a unanimous opinion on behalf of the panel, stating, "Texas does not currently recognize a legal duty owed by wholesale power generators to retail customers to provide continuous electricity to the electric grid, and ultimately to the retail customers."

The opinion further clarified that major power generators "are now statutorily precluded by the legislature from having any direct relationship with retail customers of electricity."

This separation of power generation from transmission and retail electric sales in many parts of Texas resulted from energy market deregulation in the early 2000s, with the goal of reducing energy costs, and prompted electricity market reforms aimed at avoiding future blackouts.

Under the previous system, power companies were "vertically integrated," controlling generators, transmission lines, and selling the energy they produced directly to regional customers. However, in deregulated areas of Texas, competition was introduced, creating competing energy-generating companies and retail electric providers that purchase power wholesale and then sell it to residential consumers; meanwhile, electric cooperatives in other parts of the state remained member-owned providers.

Tré Fischer, a partner at the Jackson Walker law firm representing the power companies, explained, "One consequence of that was, because of the unbundling and the separation, you also don't have the same duties and obligations [to consumers]. The structure just doesn't allow for that direct relationship and correspondingly a direct obligation to continually supply the electricity even if there's a natural disaster or catastrophic event."

In the opinion, Justice Adams noted that when designing the Texas energy market, amid renewed interest in ways to improve electricity reliability across the grid, state lawmakers "could have codified the retail customers' asserted duty of continuous electricity on the part of wholesale power generators into law."

The recent ruling applies to five representative cases chosen by the panel out of hundreds filed after the blackout. Due to this decision, it is improbable that any of the lawsuits against power companies will succeed, according to the court's interpretation.

However, plaintiffs' attorneys have indicated their intention to appeal. They may request a review of the panel's opinion by the entire First Court of Appeals or appeal directly to the state supreme court.

The state Supreme Court had previously ruled that the Electric Reliability Council of Texas (ERCOT), the state's power grid operator, enjoys sovereign immunity and cannot be sued over the blackout.

This latest opinion raises the question of who, if anyone, can be held responsible for deaths and losses resulting from the blackout, a question left unaddressed by the court. Fischer commented, "If anything [the judges] were saying that is a question for the Texas legislature."

Maryland Renewable Energy Violations highlight RPS compliance gaps as facilities selling renewable energy certificates, including waste-to-energy, biomass, and paper mills, face emissions and permit issues, prompting PSC and Attorney General scrutiny of environmental standards.

Key Points

Alleged RPS noncompliance by REC-eligible plants, prompting PSC review and potential decertification under Maryland law.

✅ Complaint targets waste-to-energy, biomass plants, and paper mills

✅ Facilities risk loss of REC certification for environmental violations

✅ PSC may investigate nonreporting; AG reviewing evidence

Many facilities that supply Maryland with renewable energy have exceeded pollution limits or otherwise broken environmental rules, violating a state law, according to a complaint sent by environmental groups to state energy and law enforcement officials.

Maryland law says that any company that contributes to a state renewable energy goal — half the state’s energy portfolio must come from renewable sources by 2030 — must “substantially comply” with rules on air and water quality and waste management. The complaint says more than two dozen power generators, including paper mills and trash incinerators, have records of formal or informal enforcement actions by environmental authorities.

For years, environmental groups have criticized Maryland policy that counts power plants that produce planet-warming carbon dioxide and health-threatening pollution as “renewable” energy generation, and similar tensions have emerged in California’s reliance on fossil fuels despite ambitious targets, but lawmakers concerned about protecting industrial jobs have resisted reforms. The renewable label qualifies the companies for subsidies drawn from energy bills across the state.

In a complaint filed this week, the groups asked the attorney general and Public Service Commission to step in.

“We’re subsidizing companies to produce dirty energy, but we’re also using ratepayer money to support companies that in many instances are paying environmental fines or just flouting the law,” said Timothy Whitehouse, executive director of Public Employees for Environmental Responsibility. “There’s no one to hold them to account in Maryland.”

A spokeswoman for Attorney General Brian Frosh said his office would review the complaint, which was signed by Whitehouse and Mike Ewall, executive director of the Energy Justice Network.

Public Service Commission officials said the facilities must notify them if found out of compliance with environmental rules, while at the federal level FERC action on aggregated DERs is shaping market participation, and the commission can then revoke certification under the state renewable energy program. In a statement, commission officials said they would launch an investigation if any facility had failed to notify them of any environmental violations, and encouraged anyone with evidence of such a transgression to file a complaint.

Companies named in the document accused the groups of painting an inaccurate picture.

“This complaint is based on misleading arguments designed to halt waste-to-energy practices that have clear environmental benefits recognized by the global scientific community,” said Jim Connolly, vice president of environment, health and safety for Wheelabrator, which owns a Baltimore trash incinerator.

Maryland launched its renewable energy program in 2004, diversifying the state’s energy portfolio with more environmentally friendly sources of power, even as regional debates over a Maine-Québec transmission line highlight cross-border impacts. Under the program, separate from the electricity they generate and sell to the grid, renewable power facilities can sell what are known as renewable energy certificates. Utilities such as Baltimore Gas and Electric Co. are required to buy a growing number of the certificates each year, essentially subsidizing the renewable energy facilities with money from ratepayer bills.

A dozen types of power generation qualify to sell the certificates: Solar, wind, geothermal and hydroelectric plants, as well as “biomass” facilities that burn wood and other organic matter, waste-to-energy plants that burn household trash and paper mills that burn a byproduct known as black liquor.

The complaint focuses on waste incinerators, biomass plants and paper mills, all of which environmental groups have cast as counter to the renewable energy program’s environmental goals, even as ACORE criticized a coal and nuclear subsidy proposal in federal proceedings.

“By subsidizing these corporations, Maryland is diverting the hard-earned income of Maryland ratepayers to wealthy corporations with poor environmental compliance records and undermining the state’s transition to clean renewable energy,” Whitehouse and Ewall wrote.

For example, they note that the Wheelabrator plant in Southwest Baltimore has been fined for exceeding mercury limits in the past. That occurred in 2011, when the plant settled with state regulators for violations in 2010 and 2009.

Connolly said there is “no question” the facility complies with Maryland’s renewable energy law.

Incinerators in Montgomery County and in Fairfax County, Virginia, that are owned by Covanta and sell the energy certificates in Maryland have been cited for accidental fires inside both facilities. The Maryland incinerator violated emissions rules in 2014, the same year that New Jersey forbade the Virginia facility from selling energy certificates into that state’s renewable energy program over concerns it wasn’t following ash testing regulations.

James Regan, a spokesman for Covanta, said both facilities “have excellent compliance records and they operate well below their permitted limits.” He said the Virginia facility is complying with ash testing requirements, and that both facilities emit far lower levels of pollutants such as particulate matter than vehicles do.

“It’s clear to us there’s a lot of misleading and wrong information in this document," Regan said.

The Environmental Protection Agency endorsed waste-to-energy facilities under former President Barack Obama because, while burning household trash emits carbon dioxide, scientists said that still had a smaller impact on global warming than sending trash to landfills, even as industry groups have backed the EPA in a legal challenge to the ACE rule as regulatory approaches shifted.

Environmentalists and community groups say the facilities still are harmful because they emit high levels of pollutants such as mercury, nitrogen oxides and lead. The concerns prompted Baltimore City Council to pass an ordinance in February that tightened emissions limits on the Wheelabrator facility, even as the new EPA pollution limits for coal and gas plants are being proposed, so dramatically that the company said it would no longer be able to operate once the rules go into effect in 2022.

The complaint does not mention the century-old Luke paper mill in Western Maryland that long faced criticism for its participation in the renewable energy program, but which owner Verso Co. closed this year.

It does say several of paper company WestRock’s mills in North Carolina and Virginia have faced both formal and informal EPA enforcement actions for violation of the Clean Water Act, including evolving EPA wastewater limits for power plants and other facilities, and the Clean Air Act. A WestRock spokesperson could not be reached for comment.

The complaint also says a large biomass facility in South Boston, Virginia, owned by the Northern Virginia Electric Cooperative has a record of noncompliance with the Clean Air Act over three years.

John Rainey, the plant’s operations director, said it “experienced some small exceedances to its permit limits,” but that it addressed the issues with Virginia environmental officials and has installed new technology.

All those plants have sold credits in Maryland.

Whitehouse said the environmental groups’ goal is to clean up Maryland’s renewable energy program. They did not file a lawsuit because he said there was no clear cause of action to take the state to court, but said he hopes the complaint nonetheless spurs action.

“It’s not acceptable in a clean energy program that we’re subsidizing some of the most dirty sources of energy,” he said. “Those sources aren’t even in compliance with the law, and no one seems to care.”

Agrivoltaics in Alberta integrates solar energy with agriculture, boosting crop yields and water conservation. The Strathmore Solar project showcases dual land use, sheep grazing for vegetation control, and PPAs that expand renewable energy capacity.

Key Points

A dual-use model where solar arrays and farming co-exist, boosting yields, saving water, and diversifying revenue.

✅ Strathmore Solar: 41 MW on 320 acres with managed sheep grazing

✅ 25-year TELUS PPA secures power and renewable energy credits

✅ Panel shade cuts irrigation needs and protects crops from extremes

Alberta is emerging as a leader in agrivoltaics—the innovative practice of integrating solar energy production with agricultural activities, aligning with the province's red-hot solar growth in recent years. This approach not only generates renewable energy but also enhances crop yields, conserves water, and supports sustainable farming practices. A notable example of this synergy is the Strathmore Solar project, a 41-megawatt solar farm located on 320 acres of leased industrial land owned by the Town of Strathmore. Operational since March 2022, it exemplifies how solar energy and agriculture can coexist and thrive together.

The Strathmore Solar Initiative

Strathmore Solar is a collaborative venture between Capital Power and the Town of Strathmore, with a 25-year power purchase agreement in place with TELUS Corporation for all the energy and renewable energy credits generated by the facility. The project not only contributes significantly to Alberta's renewable energy capacity, as seen with new solar facilities contracted at lower cost across the province, but also serves as a model for agrivoltaic integration. In a unique partnership, 400 to 600 sheep from Whispering Cedars Ranch are brought in to graze the land beneath the solar panels. This arrangement helps manage vegetation, reduce fire hazards, and maintain the facility's upkeep, all while providing shade for the grazing animals. This mutually beneficial setup maximizes land use efficiency and supports local farming operations, illustrating how renewable power developers can strengthen outcomes with integrated designs today. 

Benefits of Agrivoltaics in Alberta

The integration of solar panels with agricultural practices offers several advantages for a province that is a powerhouse for both green energy and fossil fuels already across sectors:

• Enhanced Crop Yields: Studies have shown that crops grown under solar panels can experience increased yields due to reduced water evaporation and protection from extreme weather conditions.
  
  

• Water Conservation: The shade provided by solar panels helps retain soil moisture, leading to a decrease in irrigation needs.
  
  

• Diversified Income Streams: Farmers can generate additional revenue by selling renewable energy produced by the solar panels back to the grid.
  
  

• Sustainable Land Use: Agrivoltaics allows for dual land use, enabling the production of both food and energy without the need for additional land.
  
  

These benefits are evident in various agrivoltaic projects across Alberta, where farmers are successfully combining crop cultivation with solar energy production amid a renewable energy surge that is creating thousands of jobs.

Challenges and Considerations

While agrivoltaics presents numerous benefits, there are challenges to consider as Alberta navigates challenges with solar expansion today across Alberta:

• Initial Investment: The setup costs for agrivoltaic systems can be high, requiring significant capital investment.
  
  

• System Maintenance: Regular maintenance is essential to ensure the efficiency of both the solar panels and the agricultural operations.
  
  

• Climate Adaptability: Not all crops may thrive under the conditions created by solar panels, necessitating careful selection of suitable crops.

Addressing these challenges requires careful planning, research, and collaboration between farmers, researchers, and energy providers.

Future Prospects

The success of projects like Strathmore Solar and other agrivoltaic initiatives in Alberta indicates a promising future for this dual-use approach. As technology advances and research continues, agrivoltaics could play a pivotal role in enhancing food security, promoting sustainable farming practices, and contributing to Alberta's renewable energy goals. Ongoing projects and partnerships aim to refine agrivoltaic systems, making them more efficient and accessible to farmers across the province.

The integration of solar energy production with agriculture in Alberta is not just a trend but a transformative approach to sustainable farming. The Strathmore Solar project serves as a testament to the potential of agrivoltaics, demonstrating how innovation can lead to mutually beneficial outcomes for both the agricultural and energy sectors.
