Power customers get reprieve from increases

Brain Stimulation is transforming neuromodulation, from TMS and DBS to closed loop devices, targeting neural circuits for addiction, depression, Parkinsons, epilepsy, and chronic pain, powered by advanced imaging, AI analytics, and the NIH BRAIN Initiative.

Key Points

Brain stimulation uses pulses to modulate neural circuits, easing symptoms in depression, Parkinsons, and epilepsy.

✅ Noninvasive TMS and invasive DBS modulate specific brain circuits

✅ Closed loop systems adapt stimulation via real time biomarker detection

✅ Emerging uses: addiction, depression, Parkinsons, epilepsy, chronic pain

In June 2015, biology professor Colleen Hanlon went to a conference on drug dependence. As she met other researchers and wandered around a glitzy Phoenix resort’s conference rooms to learn about the latest work on therapies for drug and alcohol use disorders, she realized that out of the 730 posters, there were only two on brain stimulation as a potential treatment for addiction — both from her own lab at Wake Forest School of Medicine.

Just four years later, she would lead 76 researchers on four continents in writing a consensus article about brain stimulation as an innovative tool for addiction. And in 2020, the Food and Drug Administration approved a transcranial magnetic stimulation device to help patients quit smoking, a milestone for substance use disorders.

Brain stimulation is booming. Hanlon can attend entire conferences devoted to the study of what electrical currents do—including how targeted stimulation can improve short-term memory in older adults—to the intricate networks of highways and backroads that make up the brain’s circuitry. This expanding field of research is slowly revealing truths of the brain: how it works, how it malfunctions, and how electrical impulses, precisely targeted and controlled, might be used to treat psychiatric and neurological disorders.

In the last half-dozen years, researchers have launched investigations into how different forms of neuromodulation affect addiction, depression, loss-of-control eating, tremor, chronic pain, obsessive compulsive disorder, Parkinson’s disease, epilepsy, and more. Early studies have shown subtle electrical jolts to certain brain regions could disrupt circuit abnormalities — the miscommunications — that are thought to underlie many brain diseases, and help ease symptoms that persist despite conventional treatments.

The National Institute of Health’s massive BRAIN Initiative put circuits front and center, distributing $2.4 billion to researchers since 2013 to devise and use new tools to observe interactions between brain cells and circuits. That, in turn, has kindled interest from the private sector. Among the advances that have enhanced our understanding of how distant parts of the brain talk with one another are new imaging technology and the use of machine learning, much as utilities use AI to adapt to shifting electricity demand, to interpret complex brain signals and analyze what happens when circuits go haywire.

Still, the field is in its infancy, and even therapies that have been approved for use in patients with, for example, Parkinson’s disease or epilepsy, help only a minority of patients, and in a world where electricity drives pandemic readiness expectations can outpace evidence. “If it was the Bible, it would be the first chapter of Genesis,” said Michael Okun, executive director of the Norman Fixel Institute for Neurological Diseases at University of Florida Health.

As brain stimulation evolves, researchers face daunting hurdles, and not just scientific ones. How will brain stimulation become accessible to all the patients who need it, given how expensive and invasive some treatments are? Proving to the FDA that brain stimulation works, and does so safely, is complicated and expensive. Even with a swell of scientific momentum and an influx of funding, the agency has so far cleared brain stimulation for only a handful of limited conditions. Persuading insurers to cover the treatments is another challenge altogether. And outside the lab, researchers are debating nascent issues, such as the ethics of mind control, the privacy of a person’s brain data—concerns that echo efforts to develop algorithms to prevent blackouts during rising ransomware threats—and how to best involve patients in the study of the human brain’s far-flung regions.

Neurologist Martha Morrell is optimistic about the future of brain stimulation. She remembers the shocked reactions of her colleagues in 2004 when she left full-time teaching at Stanford (she still has a faculty appointment as a clinical professor of neurology) to direct clinical trials at NeuroPace, then a young company making neurostimulator systems to potentially treat epilepsy patients.

“When I started working on this, everybody thought I was insane,” said Morrell. Nearly 20 years in, she sees a parallel between the story of jolting the brain’s circuitry and that of early implantable cardiac devices, such as pacemakers and defibrillators, which initially “were used as a last option, where all other medications have failed.” Now, “the field of cardiology is very comfortable incorporating electrical therapy, device therapy, into routine care. And I think that’s really where we’re going with neurology as well.”

Reaching a ‘slope of enlightenment’
Parkinson’s is, in some ways, an elder in the world of modern brain stimulation, and it shows the potential as well as the limitations of the technology. Surgeons have been implanting electrodes deep in the brains of Parkinson’s patients since the late 1990s, and in people with more advanced disease since the early 2000s.

In that time, it’s gone through the “hype cycle,” said Okun, the national medical adviser to the Parkinson’s Foundation since 2006. Feverish excitement and overinflated expectations have given way to reality, bringing scientists to a “slope of enlightenment,” he said. They have found deep brain stimulation to be very helpful for some patients with Parkinson’s, rendering them almost symptom-free by calming the shaking and tremors that medications couldn’t. But it doesn’t stop the progression of the disease, or resolve some of the problems patients with advanced Parkinson’s have walking, talking, and thinking.

In 2015, the same year Hanlon found only her lab’s research on brain stimulation at the addiction conference, Kevin O’Neill watched one finger on his left hand start doing something “funky.” One finger twitched, then two, then his left arm started tingling and a feeling appeared in his right leg, like it was about to shake but wouldn’t — a tremor.

“I was assuming it was anxiety,” O’Neill, 62, told STAT. He had struggled with anxiety before, and he had endured a stressful year: a separation, selling his home, starting a new job at a law firm in California’s Bay Area. But a year after his symptoms first began, O’Neill was diagnosed with Parkinson’s.

In the broader energy context, California has increasingly turned to battery storage to stabilize its strained grid.

Doctors prescribed him pills that promote the release of dopamine, to offset the death of brain cells that produce this messenger molecule in circuits that control movement. But he took them infrequently because he worried about insomnia as a side effect. Walking became difficult — “I had to kind of think my left leg into moving” — and the labor lawyer found it hard to give presentations and travel to clients’ offices.

A former actor with an outgoing personality, he developed social anxiety and didn’t tell his bosses about his diagnosis for three years, and wouldn’t have, if not for two workdays in summer 2018 when his tremors were severe and obvious.

O’Neill’s tremors are all but gone since he began deep brain stimulation last May, though his left arm shakes when he feels tense.

It was during that period that he learned about deep brain stimulation, at a support group for Parkinson’s patients. “I thought, ‘I will never let anybody fuss with my brain. I’m not going to be a candidate for that,’” he recalled. “It felt like mad scientist science fiction. Like, are you kidding me?”

But over time, the idea became less radical, as O’Neill spoke to DBS patients and doctors and did his own research, and as his symptoms worsened. He decided to go for it. Last May, doctors at the University of California, San Francisco surgically placed three metal leads into his brain, connected by thin cords to two implants in his chest, just near the clavicles. A month later, he went into the lab and researchers turned the device on.

“That was a revelation that day,” he said. “You immediately — literally, immediately — feel the efficacy of these things. … You go from fully symptomatic to non-symptomatic in seconds.”

When his nephew pulled up to the curb to pick him up, O’Neill started dancing, and his nephew teared up. The following day, O’Neill couldn’t wait to get out of bed and go out, even if it was just to pick up his car from the repair shop.

In the year since, O’Neill’s walking has gone from “awkward and painful” to much improved, and his tremors are all but gone. When he is extra frazzled, like while renovating and moving into his new house overlooking the hills of Marin County, he feels tense and his left arm shakes and he worries the DBS is “failing,” but generally he returns to a comfortable, tremor-free baseline.

O’Neill worried about the effects of DBS wearing off but, for now, he can think “in terms of decades, instead of years or months,” he recalled his neurologist telling him. “The fact that I can put away that worry was the big thing.”

He’s just one patient, though. The brain has regions that are mostly uniform across all people. The functions of those regions also tend to be the same. But researchers suspect that how brain regions interact with one another — who mingles with whom, and what conversation they have — and how those mixes and matches cause complex diseases varies from person to person. So brain stimulation looks different for each patient.

Each case of Parkinson’s manifests slightly differently, and that’s a bit of knowledge that applies to many other diseases, said Okun, who organized the nine-year-old Deep Brain Stimulation Think Tank, where leading researchers convene, review papers, and publish reports on the field’s progress each year.

“I think we’re all collectively coming to the realization that these diseases are not one-size-fits-all,” he said. “We have to really begin to rethink the entire infrastructure, the schema, the framework we start with.”

Brain stimulation is also used frequently to treat people with common forms of epilepsy, and has reduced the number of seizures or improved other symptoms in many patients. Researchers have also been able to collect high-quality data about what happens in the brain during a seizure — including identifying differences between epilepsy types. Still, only about 15% of patients are symptom-free after treatment, according to Robert Gross, a neurosurgery professor at Emory University in Atlanta.

“And that’s a critical difference for people with epilepsy. Because people who are symptom-free can drive,” which means they can get to a job in a place like Georgia, where there is little public transit, he said. So taking neuromodulation “from good to great,” is imperative, Gross said.

Renaissance for an ancient idea
Recent advances are bringing about what Gross sees as “almost a renaissance period” for brain stimulation, though the ideas that undergird the technology are millenia old. Neuromodulation goes back to at least ancient Egypt and Greece, when electrical shocks from a ray, called the “torpedo fish,” were recommended as a treatment for headache and gout. Over centuries, the fish zaps led to doctors burning holes into the brains of patients. Those “lesions” worked, somehow, but nobody could explain why they alleviated some patients’ symptoms, Okun said.

Perhaps the clearest predecessor to today’s technology is electroconvulsive therapy (ECT), which in a rudimentary and dangerous way began being used on patients with depression roughly 100 years ago, said Nolan Williams, director of the Brain Stimulation Lab at Stanford University.

More modern forms of brain stimulation came about in the United States in the mid-20th century. A common, noninvasive approach is transcranial magnetic stimulation, which involves placing an electromagnetic coil on the scalp to transmit a current into the outermost layer of the brain. Vagus nerve stimulation (VNS), used to treat epilepsy, zaps a nerve that contributes to some seizures.

The most invasive option, deep brain stimulation, involves implanting in the skull a device attached to electrodes embedded in deep brain regions, such as the amygdala, that can’t be reached with other stimulation devices. In 1997, the FDA gave its first green light to deep brain stimulation as a treatment for tremor, and then for Parkinson’s in 2002 and the movement disorder dystonia in 2003.

Even as these treatments were cleared for patients, though, what was happening in the brain remained elusive. But advanced imaging tools now let researchers peer into the brain and map out networks — a recent breakthrough that researchers say has propelled the field of brain stimulation forward as much as increased funding has, paralleling broader efforts to digitize analog electrical systems across industry. Imaging of both human brains and animal models has helped researchers identify the neuroanatomy of diseases, target brain regions with more specificity, and watch what was happening after electrical stimulation.

Another key step has been the shift from open-loop stimulation — a constant stream of electricity — to closed-loop stimulation that delivers targeted, brief jolts in response to a symptom trigger. To make use of the futuristic technology, labs need people to develop artificial intelligence tools, informed by advances in machine learning for the energy transition, to interpret large data sets a brain implant is generating, and to tailor devices based on that information.

“We’ve needed to learn how to be data scientists,” Morrell said.

Affinity groups, like the NIH-funded Open Mind Consortium, have formed to fill that gap. Philip Starr, a neurosurgeon and developer of implantable brain devices at the University of California at San Francisco Health system, leads the effort to teach physicians how to program closed-loop devices, and works to create ethical standards for their use. “There’s been extraordinary innovation after 20 years of no innovation,” he said.

The BRAIN Initiative has been critical, several researchers told STAT. “It’s been a godsend to us,” Gross said. The NIH’s Brain Research through Advancing Innovative Neurotechnologies (BRAIN) Initiative was launched in 2013 during the Obama administration with a $50 million budget. BRAIN now spends over $500 million per year. Since its creation, BRAIN has given over 1,100 awards, according to NIH data. Part of the initiative’s purpose is to pair up researchers with medical technology companies that provide human-grade stimulation devices to the investigators. Nearly three dozen projects have been funded through the investigator-devicemaker partnership program and through one focused on new implantable devices for first-in-human use, according to Nick Langhals, who leads work on neurological disorders at the initiative.

The more BRAIN invests, the more research is spawned. “We learn more about what circuits are involved … which then feeds back into new and more innovative projects,” he said.

Many BRAIN projects are still in early stages, finishing enrollment or small feasibility studies, Langhals said. Over the next couple of years, scientists will begin to see some of the fruits of their labor, which could lead to larger clinical trials, or to companies developing more refined brain stimulation implants, Langhals said.

Money from the National Institutes of Mental Health, as well as the NIH’s Helping to End Addiction Long-term (HEAL), has similarly sweetened the appeal of brain stimulation, both for researchers and industry. “A critical mass” of companies interested in neuromodulation technology has mushroomed where, for two decades, just a handful of companies stood, Starr said.

More and more, pharmaceutical and digital health companies are looking at brain stimulation devices “as possible products for their future,” said Linda Carpenter, director of the Butler Hospital TMS Clinic and Neuromodulation Research Facility.

‘Psychiatry 3.0’
The experience with using brain stimulation to stop tremors and seizures inspired psychiatrists to begin exploring its use as a potentially powerful therapy for healing, or even getting ahead of, mental illness.

In 2008, the FDA approved TMS for patients with major depression who had tried, and not gotten relief from, drug therapy. “That kind of opened the door for all of us,” said Hanlon, a professor and researcher at the Center for Research on Substance Use and Addiction at Wake Forest School of Medicine. The last decade saw a surge of research into how TMS could be used to reset malfunctioning brain circuits involved in anxiety, depression, obsessive-compulsive disorder, and other conditions.

“We’re certainly entering into what a lot of people are calling psychiatry 3.0,” Stanford’s Williams said. “Whereas the first iteration was Freud and all that business, the second one was the psychopharmacology boom, and this third one is this bit around circuits and stimulation.”

Drugs alleviate some patients’ symptoms while simultaneously failing to help many others, but psychopharmacology clearly showed “there’s definitely a biology to this problem,” Williams said — a biology that in some cases may be more amenable to a brain stimulation.

The exact mechanics of what happens between cells when brain circuits … well, short-circuit, is unclear. Researchers are getting closer to finding biomarkers that warn of an incoming depressive episode, or wave of anxiety, or loss of impulse control. Those brain signatures could be different for every patient. If researchers can find molecular biomarkers for psychiatric disorders — and find ways to preempt those symptoms by shocking particular brain regions — that would reshape the field, Williams said.

Not only would disease-specific markers help clinicians diagnose people, but they could help chip away at the stigma that paints mental illness as a personal or moral failing instead of a disease. That’s what happened for epilepsy in the 1960s, when scientific findings nudged the general public toward a deeper understanding of why seizures happen, and it’s “the same trajectory” Williams said he sees for depression.

His research at the Stanford lab also includes work on suicide, and obsessive-compulsive disorder, which the FDA said in 2018 could be treated using noninvasive TMS. Williams considers brain stimulation, with its instantaneity, to be a potential breakthrough for urgent psychiatric situations. Doctors know what to do when a patient is rushed into the emergency room with a heart attack or a stroke, but there is no immediate treatment for psychiatric emergencies, he said. Williams wonders: What if, in the future, a suicidal patient could receive TMS in the emergency room and be quickly pulled out of their depressive mental spiral?

Researchers are also actively investigating the brain biology of addiction. In August 2020, the FDA approved TMS for smoking cessation, the first such OK for a substance use disorder, which is “really exciting,” Hanlon said. Although there is some nuance when comparing substance use disorders, a primal mechanism generally defines addiction: the eternal competition between “top-down” executive control functions and “bottom-up” cravings. It’s the same process that is at work when one is deciding whether to eat another cookie or abstain — just exacerbated.

Hanlon is trying to figure out if the stop and go circuits are in the same place for all people, and whether neuromodulation should be used to strengthen top-down control or weaken bottom-up cravings. Just as brain stimulation can be used to disrupt cellular misfiring, it could also be a tool for reinforcing helpful brain functions, or for giving the addicted brain what it wants in order to curb substance use.

Evidence suggests many people with schizophrenia smoke cigarettes (a leading cause of early death for this population) because nicotine reduces the “hyperconnectivity” that characterizes the brains of people with the disease, said Heather Ward, a research fellow at Boston’s Beth Israel Deaconess Medical Center. She suspects TMS could mimic that effect, and therefore reduce cravings and some symptoms of the disease, and she hopes to prove that in a pilot study that is now enrolling patients.

If the scientific evidence proves out, clinicians say brain stimulation could be used alongside behavioral therapy and drug-based therapy to treat substance use disorders. “In the end, we’re going to need all three to help people stay sober,” Hanlon said. “We’re adding another tool to the physician’s toolbox.”

Decoding the mysteries of pain
Afavorable outcome to the ongoing research, one that would fling the doors to brain stimulation wide open for patients with myriad disorders, is far from guaranteed. Chronic pain researchers know that firsthand.

Chronic pain, among the most mysterious and hard-to-study medical phenomena, was the first use for which the FDA approved deep brain stimulation, said Prasad Shirvalkar, an assistant professor of anesthesiology at UCSF. But when studies didn’t pan out after a year, the FDA retracted its approval.

Shirvalkar is working with Starr and neurosurgeon Edward Chang on a profoundly complex problem: “decoding pain in the brain states, which has never been done,” as Starr told STAT.

Part of the difficulty of studying pain is that there is no objective way to measure it. Much of what we know about pain is from rudimentary surveys that ask patients to rate how much they’re hurting, on a scale from zero to 10.

Using implantable brain stimulation devices, the researchers ask patients for a 0-to-10 rating of their pain while recording up-and-down cycles of activity in the brain. They then use machine learning to compare the two streams of information and see what brain activity correlates with a patient’s subjective pain experience. Implantable devices let researchers collect data over weeks and months, instead of basing findings on small snippets of information, allowing for a much richer analysis.

Pennsylvania Electricity Market Deregulation has driven competitive pricing, leveraged low-cost natural gas, and spurred private investment, jobs, and efficient power plants, while nuclear subsidies threaten wholesale market signals and long-term consumer savings.

Key Points

Policy that opens generation to competition, leverages cheap gas, lowers rates, and resists subsidies for nuclear plants.

✅ Competitive wholesale pricing benefits consumers statewide

✅ Gas-driven plants add efficient, flexible capacity and jobs

✅ Nuclear subsidies distort market signals and raise costs

For decades, the government regulation of Pennsylvania's electricity markets dictated all aspects of power generation resources in the state, thus restricting market-driven prices for consumers and hindering new power plant development and investment.

Deregulation has enabled competitive markets to drive energy prices downward, as recent grid auction payouts fell 64% indicate, which has transformed Pennsylvania from a higher-electricity-cost state to one with prices below the national average.

Recently, the economic advantage of abundant low-cost natural gas has spurred an influx of billions of dollars of private capital investment and thousands of jobs to construct environmentally responsible natural gas power generation facilities throughout the commonwealth — including our three power generation facilities in operation and one presently under construction.

Calpine is an independent power provider with a national portfolio of 80 highly efficient power plants in operation or under construction with an electric generating capacity of approximately 26,000 megawatts. Collectively, these resources can provide sufficient power for more than 30 million residential homes. We are not a regulated utility receiving a guaranteed rate of return on investment. Rather, Calpine competes to sell wholesale power into the electric markets, and the economics of supply and demand are fundamental to the success of our business.

Pennsylvania's deregulated electricity market is working. Consumers are benefiting from low-cost natural gas, as broader evidence shows competition benefits consumers and the environment across markets, and companies such as Calpine are investing billions of dollars and creating thousands of jobs to build advanced, energy efficient, environmentally responsible and flexible power generating facilities.

There are presently seven electric generating projects under construction in the commonwealth, representing about a $7 billion capital investment that will produce about 7,000 megawatts of efficient electrical power, with additional facilities being planned.

Looking back 20 years following the enactment of the Pennsylvania Electricity Generation Customer Choice and Competition Act, Pennsylvania's regulators and policymakers must conclude that the results of a free and fair market-driven structure have delivered indisputable benefits to the consumer, even amid potential winter rate spikes for residents, and the Pennsylvania economy.

While consumers are now reaping the benefits of open and competitive electricity markets, we see challenges on the horizon that could threaten the foundation of those markets. Due to pressure from nuclear power generators, state policymakers throughout the nation have been increasing efforts to impact the generation mix in their respective states by offering ratepayer funded subsidies to existing nuclear generation resources or by considering a market structure overhaul in New England.

Subsidizing one power generation type over others is having a significant, negative impact on wholesale electric markets, competitive retails markets and ultimately the cost the consumer will have to pay, and can exacerbate disruptions in coal and nuclear industries that strain the economy and risk brownouts.

In Pennsylvania, these subsidies would follow nearly $9 billion already paid by ratepayers to help the commonwealth's nuclear industry transition from regulated to competitive energy markets.

The deregulation of Pennsylvania's electricity markets in the late 1990s allowed the nuclear industry to receive billions of dollars from ratepayers to recover "stranded costs" related to investments in the commonwealth's nuclear plants. These costs were negotiated amounts based on settlements with Pennsylvania's Public Utility Commission to allow the nuclear industry to prepare and transition to competitive electricity markets.

Enough is enough. Regulatory or governmental interference in well functioning markets does not lead to better outcomes. Pennsylvania's state Legislature should not pick winners and losers by enacting legislation that would create an uneven playing field that subsidizes nuclear generating resources in the commonwealth.

William Ferguson is regional vice president for Calpine Corp.

UK Electricity-Gas Price Decoupling aims to reform wholesale electricity pricing under the Energy Security Bill, shielding households from gas price spikes, supporting renewables, and easing the cost-of-living crisis through market redesign and transparent tariffs.

Key Points

Policy to decouple power prices from gas via the Energy Security Bill, stabilizing bills and reflecting renewables

✅ Breaks gas-to-power pricing link to cut electricity costs

✅ Reduces volatility; shields households from global gas shocks

✅ Highlights benefits of renewables and market transparency

Britons could be handed relief on rocketing household bills under Government plans to sever the link between the prices of gas and electricity, including proposals to restrict energy prices in the market, it has emerged.

Ministers are set to bring forward new laws under the Energy Security Bill to overhaul the UK's energy market in the face of the current cost-of-living crisis.

They have promised to provide greater protection for Britons against global fluctuations in energy prices, through a price cap on bills among other measures.

The current worldwide crisis has been exacerbated by the Ukraine war, which has sent gas prices spiralling higher.

Under the current make-up of Britain's energy market, soaring natural gas prices have had a knock-on effect on electricity costs.

But it has now been reported the new legislation will seek to prevent future shocks in the global gas market having a similar impact on electricity prices.

Yet the overhaul might not come in time to ease high winter energy costs for households ahead of this winter.

According to The Times, Business Secretary Kwasi Kwarteng will outline proposals for reforms in the coming weeks.

These will then form part of the Energy Security Bill to be introduced in the autumn, with officials anticipating a decrease in energy bills by April.

The newspaper said the plans will end the current system under which the wholesale cost of gas effectively determines the price of electricity for households.

Although more than a quarter of Britain's electricity comes from renewable sources, under current market rules it is the most expensive megawatt needed to meet demand that determines the price for all electricity generation.

This means that soaring gas prices have driven up all electricity costs in recent months, even though only around 40% of UK electricity comes from gas power stations.

Energy experts have compared the current market to train passengers having to pay the peak-period price for every journey they make.

One Government source told The Times: 'In the past it didn’t really matter because the price of gas was reasonably stable.

'Now it seems completely crazy that the price of electricity is based on the price of gas when a large amount of our generation is from renewables.'

It was also claimed ministers hope the reforms will make the market more transparent and emphasise to consumers the benefits of decarbonisation, amid an ongoing industry debate over free electricity for consumers.

A Government spokesperson said: 'The high global gas prices and linked high electricity prices that we are currently facing have given added urgency to the need to consider electricity market reform.

U.S. EV and Hybrid Sales 2024 show slower adoption versus gas-powered cars, as charging infrastructure gaps, range anxiety, higher upfront costs, and affordability concerns persist despite incentives, battery tech advances, and expanding fast-charging networks.

Key Points

They represent 10-15% of U.S. car sales, lagging gas models due to costs, charging gaps, range anxiety, and access.

✅ 10-15% of U.S. auto sales; gas cars dominate

✅ Barriers: upfront cost, limited charging, range anxiety

✅ Incentives, battery tech, and networks may boost adoption

Sales of hybrid and electric vehicles (EVs) in the U.S. are continuing to trail behind traditional gas-powered vehicles in 2024, despite significant advancements in automotive technology and growing public awareness of environmental concerns. While the electric vehicle market has seen steady growth and recent sales momentum over the past few years, the gap between EVs and gasoline-powered cars remains wide.

In 2024, hybrid and electric vehicles are projected to account for roughly 10-15% of total car sales in the U.S., a figure that, though significant, still lags far behind the sales of gas-powered vehicles and follows a Q1 2024 EV market share dip in the U.S., according to recent data. Analysts point to several factors contributing to this slower adoption rate, including higher upfront costs, limited charging infrastructure, and consumer concerns over range anxiety. Additionally, while EVs and hybrids offer lower lifetime operating costs, the initial price difference remains a hurdle for many prospective buyers.

One of the key challenges for EV sales continues to be the perception of cost, even as analyses show they can be better for the planet and often your budget over time. While federal and state incentives have made EVs more affordable, especially for lower-income buyers, the price tag for many electric models remains steep, particularly for higher-end vehicles. Even with government rebates, EVs can still be priced higher than their gasoline counterparts, making them less accessible for middle-class consumers. Many potential buyers are also hesitant to make the switch, unsure if the long-term savings will outweigh the initial investment.

Another critical factor is the limited charging infrastructure in many parts of the country. Though major cities have seen significant improvements in charging stations, rural areas and smaller towns still lack the necessary infrastructure to support widespread EV use. This uneven distribution of charging stations leads to concerns about being stranded in areas without access to fast-charging options. While automakers are working on expanding charging networks, the pace of this development is slow, and EVs won't go mainstream until key problems are fixed according to industry leaders.

Range anxiety is also a continuing issue, despite improvements in battery technology. Though newer electric vehicles can go further on a single charge than ever before, the range of many EVs still doesn't meet the expectations of some drivers, particularly those who regularly take long road trips or live in rural areas. The longer charging times and the necessity of planning routes around charging stations add to the hesitation, especially when gasoline-powered vehicles provide greater convenience and flexibility.

The shift toward EVs is further hindered by the continued dominance of gas-powered cars in the market. Gasoline vehicles benefit from decades of development, an extensive fueling infrastructure, and familiarity with the technology. For many consumers, the convenience, affordability, and ease of use of gas-powered vehicles still outweigh the benefits of switching to an electric alternative. Additionally, with fluctuating fuel prices, many drivers continue to find gas-powered cars relatively cost-effective in terms of daily commuting, especially when compared to the current costs of EV ownership.

Despite these challenges, there is hope for a future shift. The federal government’s push for stricter emissions regulations and tax incentives continues to fuel growth in the electric vehicle market. As automakers ramp up production and more affordable options become available, EV sales are expected to increase in the coming years. Companies like Tesla, Ford, whose hybrids are getting a boost, and General Motors are leading the charge, while new manufacturers like Rivian and Lucid Motors are offering alternatives to traditional gasoline vehicles.

Furthermore, the development of new technologies, such as solid-state batteries and faster charging systems, could help alleviate some of the current drawbacks of electric vehicles. If these advancements reach mass-market production in the next few years, they could help make EVs a more attractive and practical option for consumers, aligning with within-a-decade adoption forecasts from some industry observers.

In conclusion, while hybrid and electric vehicles are growing in popularity, gas-powered vehicles continue to dominate the U.S. car market in 2024. Challenges such as high upfront costs, limited charging infrastructure, and concerns about range persist, making it difficult for many consumers to make the switch to electric even as they ask if it's time to buy an EV in 2024. However, with continued investment in technology and infrastructure, the gap between EVs and gas-powered vehicles could narrow in the years to come.

Texas Gulf Coast Power Outages from Harvey continue as flooding, high winds, and downed lines paralyze Houston and coastal utilities, while restoration crews from out-of-state work to repair infrastructure and restore electricity across impacted communities.

Key Points

Power disruptions across Houston and the Gulf Coast from Harvey, driven by flooding, wind damage, and blocked access.

✅ CenterPoint warns multi-day outages in flooded zones.

✅ AEP Texas aided by crews from Kentucky, Illinois, Missouri.

✅ Entergy expects more outages as storm nears Galveston.

Hundreds of thousands of Texans were without power along the Gulf Coast as Tropical Storm Harvey left parts of the Houston area under water, with extended Houston outages compounding response efforts.

There were roughly 280,000 customers without power along the Texas's coast and in Houston and the surrounding areas on Monday, according to reported outages by the state's investor-owned utilities. Harvey, which made landfall on Friday, caused devastating flooding and knocked out power lines along its destructive path, similar to the Louisiana grid rebuild after Laura that required weeks of restoration.

CenterPoint Energy reported more than 100,000 outages earlier on Monday, though that figure was down to 91,744 shortly after 1 p.m. on Monday.

The company said it was unable to access hard-hit areas until floodwaters recede and electric infrastructure dries out, a challenge that, as seen in Florida power restoration efforts elsewhere, has taken weeks to resolve. Outages in the most flooded areas could last for several days, CenterPoint warned.

AEP Texas's coverage area south of Houston had 150,500 customers without electricity as of 11 a.m. ET on Monday. That was down from the peak of its outages on Saturday afternoon, which affected 220,000 customers.

Former FEMA deputy director: Texas has already begun recovery from storm  1:54 PM ET Mon, 28 Aug 2017 | 05:57

Corpus Christi and the surrounding areas along the Gulf Coast were still experiencing the most outages, while persistent Toronto outages after a spring storm underscored how long recovery can take in urban areas. AEP credited assistance from out-of-state workers for helping to get the lights back on.

"Thousands of resources have arrived from across the country to help AEP Texas with restoration efforts following this historic weather event. Crews from Kentucky, Illinois, Missouri and other states have arrived and are working on restoring power to those impacted by Hurricane Harvey," AEP said in a statement.

Entergy reported 29,500 customers were without power on Monday in areas north of Houston. The company warned that additional outages were expected if Harvey moves inland near the island city of Galveston on Wednesday as anticipated, a pattern similar to New Orleans during Ida where electricity failed despite levees holding.

Houston, Beaumont and Victoria are expected to see continued periods of torrential rain through Tuesday, before Harvey begins to move north on Wednesday and out of the flood zone by Thursday.

"Our crews are safely restoring power as quickly as possible, but the continued wind, rain and flooding are having an impact on restoration efforts," Entergy said in a statement.

South of Houston, about 7,500 Texas New Mexico Power Company customers were still experiencing outages, according to the company's outage map.

US Power Grid Cyberattacks target utilities and nuclear plants, probing SCADA, ICS, and business networks at sites like Wolf Creek; suspected Russian actors, malware, and spear-phishing trigger DHS and FBI alerts on critical infrastructure resilience.

Key Points

Intrusions on energy networks probing ICS and SCADA, seeking persistence and elevating risks to critical infrastructure.

✅ Wolf Creek nuclear plant targeted; no operational systems breached

✅ Attackers leveraged stolen credentials, malware, and spear-phishing

✅ DHS and FBI issued alerts; utilities enhance cyber resilience

Hackers working for a foreign government recently breached at least a dozen US power plants, including the Wolf Creek nuclear facility in Kansas, according to current and former US officials, sparking concerns the attackers were searching for vulnerabilities in the electrical grid.

The rivals could be positioning themselves to eventually disrupt the nation’s power supply, warned the officials, who noted that a general alert, prompting a renewed focus on protecting the U.S. power grid, was distributed to utilities a week ago. Adding to those concerns, hackers recently infiltrated an unidentified company that makes control systems for equipment used in the power industry, an attack that officials believe may be related.

The chief suspect is Russia, according to three people familiar with the continuing effort to eject the hackers from the computer networks. One of those networks belongs to an ageing nuclear generating facility known as Wolf Creek -- owned by Westar Energy Inc, Great Plains Energy Inc, and Kansas Electric Power Cooperative Inc -- on a lake shore near Burlington, Kansas.

The possibility of a Russia connection is particularly worrying, former and current official s say, because Russian hackers have previously taken down parts of the electrical grid in Ukraine and appear to be testing increasingly advanced tools, including cyber weapons to disrupt power grids, to disrupt power supplies.

The hacks come as international tensions have flared over US intelligence agencies’ conclusion that Russia tried to influence the 2016 presidential election, and amid U.S. government condemnation of Russian power-grid hacking in recent advisories. The US, which has several continuing investigations into Russia’s activities, is known to possess digital weapons capable of disrupting the electricity grids of rival nations.

“We don’t pay attention to such anonymous fakes,” Kremlin spokesman Dmitry Peskov said, in response to a request to comment on alleged Russian involvement.

It was unclear whether President Donald Trump was planning to address the cyber attacks at his meeting on Friday with Russian President Vladimir Putin. In an earlier speech in Warsaw, Trump called out Russia’s “destabilising activities” and urged the country to join “the community of responsible nations.”

The Department of Homeland Security and Federal Bureau of Investigation said they are aware of a potential intrusion in the energy sector. The alert issued to utilities cited activities by hackers since May.

“There is no indication of a threat to public safety, as any potential impact appears to be limited to administrative and business networks,” the government agencies said in a joint statement.

The Department of Energy also said the impact appears limited to administrative and business networks and said it was working with utilities and grid operators to enhance security and resilience.

“Regardless of whether malicious actors attempt to exploit business networks or operational systems, we take any reports of malicious cyber activity potentially targeting our nation’s energy infrastructure seriously and respond accordingly,” the department said in an emailed statement.

Representatives of the National Security Council, the Director of National Intelligence and the Nuclear Regulatory Commission declined to comment. While Bloomberg News was waiting for responses from the government, the New York Times reported that hacks were targeting nuclear power stations.

The North American Electric Reliability Corp, a nonprofit that works to ensure the reliability of the continent’s power system, said it was aware of the incident and was exchanging information with the industry through a secure portal.

“At this time, there has been no bulk power system impact in North America,” the corporation said in an emailed statement.

In addition, the operational controls at Wolf Creek were not pierced, according to government officials, even as attackers accessed utility control rooms elsewhere in the U.S., according to separate reports. “There was absolutely no operational impact to Wolf Creek,” Jenny Hageman, a spokeswoman for the nuclear plant, said in a statement to Bloomberg News.

“The reason that is true is because the operational computer systems are completely separate from the corporate network.”

Determining who is behind an attack can be tricky. Government officials look at the sophistication of the tools, among other key markers, when gauging whether a foreign government is sponsoring cyber activities.

Several private security firms, including Symantec researchers, are studying data on the attacks, but none has linked the work to a particular hacking team or country.

“We don’t tie this to any known group at this point,” said Sean McBride, a lead analyst for FireEye Inc, a global cyber security firm. “It’s not to say it’s not related, but we don’t have the evidence at this point.”

US intelligence officials have long been concerned about the security of the country’s electrical grid. The recent attack, striking almost simultaneously at multiple locations, is testing the government’s ability to coordinate an effective response among several private utilities, state and local officials, and industry regulators.

Specialised teams from Homeland Security and the FBI have been scrambled to help extricate the hackers from the power stations, in some cases without informing local and state officials. Meanwhile, the US National Security Agency is working to confirm the identity of the hackers, who are said to be using computer servers in Germany, Italy, Malaysia and Turkey to cover their tracks.

Many of the power plants are conventional, but the targeting of a nuclear facility adds to the pressure. While the core of a nuclear generator is heavily protected, a sudden shutdown of the turbine can trigger safety systems. These safety devices are designed to disperse excess heat while the nuclear reaction is halted, but the safety systems themselves may be vulnerable to attack.

Homeland Security and the FBI sent out a general warning about the cyber attack to utilities and related parties on June 28, though it contained few details or the number of plants affected. The government said it was most concerned about the “persistence” of the attacks on choke points of the US power supply. That language suggests hackers are trying to establish backdoors on the plants’ systems for later use, according to a former senior DHS official who asked not to be identified.

Those backdoors can be used to insert software specifically designed to penetrate a facility’s operational controls and disrupt critical systems, according to Galina Antova, co-founder of Claroty, a New York firm that specialises in securing industrial control systems.

“We’re moving to a point where a major attack like this is very, very possible,” Antova said. “Once you’re into the control systems -- and you can get into the control systems by hacking into the plant’s regular computer network -- then the basic security mechanisms you’d expect are simply not there.”

The situation is a little different at nuclear facilities. Backup power supplies and other safeguards at nuclear sites are meant to ensure that “you can’t really cause a nuclear plant to melt down just by taking out the secondary systems that are connected to the grid,” Edwin Lyman, a nuclear expert with the Union of Concerned Scientists, said in a phone interview.

The operating systems at nuclear plants also tend to be legacy controls built decades ago and don’t have digital control systems that can be exploited by hackers. Wolf Creek, for example, began operations in 1985. “They’re relatively impervious to that kind of attack,” Lyman said.

The alert sent out last week inadvertently identified Wolf Creek as one of the victims of the attack. An analysis of one of the tools used by the hackers had the stolen credentials of a plant employee, a senior engineer. A US official acknowledged the error was not caught until after the alert was distributed.

According to a security researcher who has seen the report, the malware that activated the engineer’s username and password was designed to be used once the hackers were already inside the plant’s computer systems.

The tool tries to connect to non-public computers, and may have been intended to identify systems related to Wolf Creek’s generation plant, a part of the facility typically more modern than the nuclear reactor control room, according to a security expert who asked to note be identified because the alert is not public.

Even if there is no indication that the hackers gained access to those control systems, the design of the malware suggests they may have at least been looking for ways to do so, the expert said.

Stan Luke, the mayor of Burlington, the largest community near Wolf Creek, which is surrounded by corn fields and cattle pastures, said he learned about a cyber threat at the plant only recently, and then only through golfing buddies.

With a population of just 2,700, Burlington boasts a community pool with three water slides and a high school football stadium that would be the envy of any junior college. Luke said those amenities lead back to the tax dollars poured into the community by Wolf Creek, Coffey County’s largest employer with some 1,000 workers, 600 of whom live in the county.

E&E News first reported on digital attacks targeting US nuclear plants, adding it was code-named Nuclear 17. A senior US official told Bloomberg that there was a bigger breach of conventional plants, which could affect multiple regions.

Industry experts and US officials say the attack is being taken seriously, in part because of recent events in Ukraine. Antova said that the Ukrainian power grid has been disrupted at least twice, first in 2015, and then in a more automated attack last year, suggesting the hackers are testing methods.

Scott Aaronson, executive director for security and business continuity at the Edison Electric Institute, an industry trade group, said utilities, grid operators and federal officials were already dissecting the attack on Ukraine’s electric sector to apply lessons in North America before the US government issued the latest warning to “energy and critical manufacturing sectors”. The current threat is unrelated to recently publicised ransomware incidents or the CrashOverride malware, Mr Aaronson said in an emailed statement.

Neither attack in Ukraine caused long-term damage. But with each escalation, the hackers may be gauging the world’s willingness to push back.

“If you think about a typical war, some of the acts that have been taken against critical infrastructure in Ukraine and even in the US, those would be considered crossing red lines,” Antova said.
