You know the old adage: "If you don't like the weather here, wait five minutes." Texas weather is not just unpredictable; it can be downright bipolar. I don't need to remind you of the knockout punch Old Man Winter delivered last February, even to parts of the state where hard freezes are few and a "snow event" usually amounts to a dusting. It will be a long time before Texans forget spending a week without power in single-digit temperatures — huddled together in their homes under mountains of blankets — with no heat, no way to bathe or cook, and no escape.

The massive power outages of Valentine's Day week spurred public outrage and a full-throated demand that state leaders take decisive steps to make Texas' electric grid sustainable. The legislature was only a month into its 140-day regular session at the time, but still failed to do anything substantial to fix the grid before adjourning May 31.

Now — well ahead of the hottest days of summer — Texans are wondering why the Electric Reliability Council of Texas (ERCOT) is already asking them to set their thermostats at 78 degrees, turn off lights, avoid using their ovens or doing laundry in the evenings, and otherwise conserve energy. It was ERCOT's second such call since April. Some local energy companies have recommended setting thermostats even higher, and local rolling blackouts have continued in Dallas, Houston, and elsewhere in the state throughout the months of June and July. That may be fine for some people during Texas' scorching summer heat, but for others, it is untenable. For the elderly or infirmed, it could be deadly.

Experts have warned the grid is unreliable, the system is strained, and homeowners and businesses hover at near-constant risk for blackouts, unless the state does more to weatherize the grid, bring more generators back online, and provide more emergency backup power. Meanwhile, when temperatures hit triple digits and stay there for days, the blackout risks will skyrocket.

But there is one obvious solution to grid instability that will enable Texans to keep their homes and businesses comfortably cool during the hot summer months ahead, without setting their thermostats higher or timing their activities to government guidelines. Widespread distributed generation of solar energy, instead of the current emphasis on remotely located utility-scale solar, would provide a highly effective, long-term solution to decreasing strain on the ERCOT power grid.

That means dramatically increasing the number of solar installations on residential and commercial properties statewide. Consider the distance and infrastructure required to bring power from a West Texas solar farm to the state's big cities. That's not only a costly undertaking, it exposes the system to many vulnerabilities along the way. It makes more sense to install solar panels on-site, behind the meter, and pair them with storage for backup power.

The logic is simple: Increasing the number of homes and businesses with on-site solar power would decrease the burden on the grid and help insulate it against failure. Further, by installing home batteries such as the Tesla Powerwall for backup power, residents can control their own power supply and ensure its reliability, even during extreme weather events—summer or winter.

These technologies are cost-efficient and readily available today. A few months ago, Congress extended the 26 percent federal solar investment tax credit (ITC) — which also applies to batteries paired with solar — through 2021 (dropping to 22 percent in 2022), making the move to solar and backup power even more sensible.

State leaders have tried to lay the blame for last winter's power outages on renewable energy. But failures of natural gas power plants, not renewable generators, caused the grid failures that led to those deadly blackouts.

On July 6, months after declaring "everything that needed to be done was done to fix the power grid in Texas," Governor Abbott ordered the PUC to take steps to overhaul the state's electric system. But the solutions he's offering—like constructing new coal, gas, and nuclear power plants and building their transmission lines faster—are giveaways to the fossil fuel industry and will take a long time to complete. Texas needs reliable power NOW.

Meanwhile, state officials are increasingly emphasizing conserving power during extreme temperatures, which suggests they don't even believe their assurances that no more blackouts lie ahead. On-site solar power is the obvious solution, both today and for the long-term health of our rapidly growing state and rapidly warming planet.

Expert: Texas must grow its solar infrastructure to prevent more weather-related power outages

guest column

As Texans begin to recover from last month's once-in-a-century winter storm, many wonder how the state — an icon of the oil and gas industry and home to Houston, "the energy capital of the world" — was thrust into darkness for days on end.

When the Texas power grid began failing in communities statewide, many in positions of power quickly laid the blame at the feet of the renewables industry. But with solar and wind power accounting for only 28.6 percent of the state's energy supply, clearly, renewables were not the sole, or even primary, culprits responsible for the massive outages. The facts point to a much more complex set of circumstances — a series of extreme weather events, one after the other; a burgeoning population; and a grossly unprepared system — all of which combined to cause an increasingly strained, aging grid to fail spectacularly.

The events of last month were a not-so-subtle demonstration of the inadequacy of our current power structure, but what does that mean for the future of Texas energy? Obviously, Texas leaders and the Electric Reliability Council of Texas (ERCOT) must begin updating the state's grid with the resources necessary to sustain the rapidly increasing demand for reliable power. Undoubtedly, that will cause a hike in consumer energy costs, especially in deregulated markets like Houston, where profitability and demand drive prices.

Widespread distributed generation of solar energy—rather than the state's current emphasis on utility-scale solar generation — would provide a highly effective, long-term solution to minimizing strain on Texas' power grid. This means dramatically increasing the number of local solar installations on residential and commercial properties statewide. Think about it: The distance and infrastructure required to bring power from West Texas solar farms to the state's urban centers leaves too much room for vulnerabilities. Solar makes more sense on-site, behind the meter, and paired with storage for backup power.

Simply stated, the more businesses and residences who have solar power, the less burden on the grid and the more insulated the grid is against failure. Further, by installing batteries such as the Tesla Powerwall for backup power, solar customers control their own power supply and ensure its reliability, even during extreme weather events like the one we just experienced. These batteries are mass market-ready, reliable and cost-efficient today.

With the increasing volatility of the Texas energy market, home and business owners are finding solar is a more appealing investment than ever before.

The amount of solar power required to power a home or business depends on the amount of energy the owner seeks to offset. For example, a solar array geared toward reducing an energy bill will be significantly smaller than a system designed to take the customer off the grid entirely. Backup power solutions are similarly dependent, with options ranging from a single battery capable of powering small household appliances to a bank of several batteries or a generator able to power a whole household or commercial space. Either way, the combination of solar power and backup provides reliability many Texans wished they had during the record freeze we just endured.

The public outcry over the massive power outages has laid a mandate at the feet of state leaders: Do what is necessary to make the power grid sustainable. At the same time, utilities statewide are looking at what they can do to increase reliability in their own communities. Deregulated energy prices will only rise because of continuing population growth and the need to update grid infrastructure.

No matter how you look at it, enlarging the state's independent solar infrastructure is a reliable way to protect businesses and homeowners alike against surging energy costs and weather-related power outages.

Now is the time for Houstonians to invest in solar energy, says expert

Guest column

Largely due to the growing popularity and falling prices of solar energy in Texas, including incentives at the federal, state, and local level, the number of solar panel installations continues to trend upward throughout the state and especially in Houston.

For the third year in a row, Houston was named the top municipal user of green energy in the nation by the United States EPA, using more than 1 billion kilowatt hours (kWh) of solar and wind power. With 92 percent of the city of Houston's energy coming from green power, solar has solidified its place in the Houston energy market.

With solar panel system prices dropping 38 percent over the past five years, solar power is also growing in popularity among individual homeowners and business owners who want to take control of their energy costs and become more self-sufficient.

As the recent COVID-19 pandemic continues to shake industries across the nation, Freedom Solar is working tirelessly to keep our team safe, healthy, and employed. Solar installers provide critical electric generation infrastructure that helps us reduce the strain on the ERCOT grid, especially with higher electricity usage as people stay at home under local shelter in place orders and as we head into the warmer spring and summer months.

The health and safety of our customers and employees is our top priority, and as an essential business we are following strict operating protocols that are in line with the guidance provided by local, state, and federal authorities. Although these challenging times often result in a pause in investments, I argue that for customers who have been considering investing in solar, now is still the time to do so.

During these tumultuous times, for many home and business owners, investing in solar energy remains appealing as a smart and stable financial decision. A solar power system is an income-producing asset that will generate a stable return for 25 or more years. The ability to finance that investment without putting cash down upfront allows customers to get the financial benefits of solar now while keeping their money in the securities markets until they recover from the current economic downturn.

Due to the COVID-19 pandemic, overseas manufacturing has been disrupted for months, resulting in shortages in the global supply chain across many industries. These shortages could increase the price of solar panels, inverters and related equipment if US warehouses run low on inventory. For customers who have long been on the fence about investing in solar, I would urge them to reevaluate the numbers now in anticipation of potential price increases in the coming months in the wake of COVID-19.

Additional macro trends and current events continue to demonstrate the value of home solar power. According to a 2020 study by the financial institution Fundera, the number of regular telecommuting employees has grown by 115% since 2005. As more and more people are required to work remotely, especially during the current and indefinite "Stay in Place" orders, electricity usage and utilities have inevitably increased for many households.

Investing in solar for your home can help offset increased utility costs, especially while working remotely and in the rapidly approaching summer months. Current events may be accelerating the long-term trend, and even when the immediate crisis is over, the way many people work could be transformed.

As the energy industry continues to evolve, the reasons why Houston customers choose to invest in solar power evolve and grow. Going solar is no longer solely a testament to your sustainability practices but also a sound long-term investment. The federal solar tax credit — also known as the investment tax credit (ITC) — allows homeowners and businesses to deduct a significant percentage of the cost of installing solar from their federal income taxes.

The credit remains at 26 percent for the remainder of 2020 but will decrease to 22 percent in 2021 and then in 2022 will drop to 10 percent for businesses and will go away entirely for homeowners. With more than 90 percent of Houston's energy consumption deriving from green power, it is clear that solar is here to stay.

Houston-area lab grows with focus on mobile diagnostics and predictive medicine

mobile medicine

When it comes to healthcare, access can be a matter of life and death. And for patients in skilled nursing facilities, assisted living or even their own homes, the ability to get timely diagnostic testing is not just a convenience, it’s a necessity.

That’s the problem Principle Health Systems (PHS) set out to solve.

Founded in 2016 in Clear Lake, Texas, PHS began as a conventional laboratory but quickly pivoted to mobile diagnostics, offering everything from core blood work and genetic testing to advanced imaging like ultrasounds, echocardiograms, and X-rays.

“We were approached by a group in a local skilled nursing facility to provide services, and we determined pretty quickly there was a massive need in this area,” says James Dieter, founder, chairman and CEO of PHS. “Turnaround time is imperative. These facilities have an incredibly sick population, and of course, they lack mobility to get the care that they need.”

What makes PHS unique is not only what they do, but where they do it. While they operate one of the largest labs serving skilled nursing facilities in the state, their mobile teams go wherever patients are, whether that’s a nursing home, a private residence or even a correctional facility.

Diagnostics, Dieter says, are at the heart of medical decision-making.

“Seventy to 80 percent of all medical decisions are made from diagnostic results in lab and imaging,” he says. “The diagnostic drives the doctor’s or the provider’s next move. When we recognized a massive slowdown in lab results, we had to innovate to do it faster.”

Innovation at PHS isn’t just about speed; it’s about accessibility and precision.

Chris Light, COO, explains: “For stat testing, we use bedside point-of-care instruments. Our phlebotomists take those into the facilities, test at the bedside, and get results within minutes, rather than waiting days for results to come back from a core lab.”

Scaling a mobile operation across multiple states isn’t simple, but PHS has expanded into nine states, including Texas, Oklahoma, Kansas, Missouri and Arizona. Their model relies on licensed mobile phlebotomists, X-ray technologists and sonographers, all trained to provide high-level care outside traditional hospital settings.

The financial impact for patients is significant. Instead of ambulance rides and ER visits costing thousands, PHS services often cost just a fraction, sometimes only tens or hundreds of dollars.

“Traditionally, without mobile diagnostics, the patient would be loaded into a transportation vehicle, typically an ambulance, and taken to a hospital,” Dieter says. “Our approach is a fraction of the cost but brings care directly to the patients.”

The company has also embraced predictive and personalized medicine, offering genetic tests that guide medication decisions and laboratory tests that predict cognitive decline from conditions like Alzheimer's and Parkinson’s.

“We actively look for complementary services to improve patient outcomes,” Dieter says. “Precision medicine and predictive testing have been a great value-add for our providers.”

Looking to the future, PHS sees mobile healthcare as part of a larger trend toward home-based care.

“There’s an aging population that still lives at home with caretakers,” Dieter explains. “We go into the home every day, whether it’s an apartment, a standalone home, or assisted living. The goal is to meet patients where they are and reduce the need for hospitalization.”

Light highlighted another layer of innovation: predictive guidance.

“We host a lot of data, and labs and imaging drive most treatment decisions,” Light says. “We’re exploring how to deploy diagnostics immediately based on results, eliminating hours of delay and keeping patients healthier longer.”

Ultimately, innovation at PHS isn’t just about technology; it’s about equity.

“There’s an 11-year life expectancy gap between major metro areas and rural Texas,” Dieter says. “Our innovation has been leveling the field, so everyone has access to high-quality diagnostics and care, regardless of where they live.”

Aegis Aerospace appoints Houston space leader as new president

moving up

Houston-based Aegis Aerospace's current chief strategy officer, Matt Ondler, will take on the additional role of president on Jan. 1. Ondler will succeed Bill Hollister, who is retiring.

“Matt's vision, experience, and understanding of our evolving markets position us to build on our foundation and pursue new frontiers,” Stephanie Murphy, CEO of Aegis Aerospace, said in a news release.

Hollister guided Aegis Aerospace through expansion and innovation in his three years as president, and will continue to serve in the role of chief technology officer (CTO) for six months and focus on the company's technical and intellectual property frameworks.

"Bill has played an instrumental role in shaping the success and growth of our company, and his contributions leave an indelible mark on both our culture and our achievements," Murphy said in a news release.

Ondler has a background in space hardware development and strategic leadership in government and commercial sectors. Ondler founded subsea robots and software company Houston Mechatronics, Inc., now known as Nauticus Robotics, and also served as president, CTO and CSO during a five-year tenure at Axiom Space. He held various roles in his 25 years at NASA and was also named to the Texas Aerospace Research and Space Economy Consortium Executive Committee last year.

"I am confident that with Matt at the helm as president and Bill supporting us as CTO, we will continue to build on our strong foundation and further elevate our impact in the space industry," Murphy said in a news release. "Matt's vision, experience, and understanding of our evolving markets position us to build on our foundation and pursue new frontiers."

Rice University launches new center to study roots of Alzheimer’s and Parkinson’s

neuro research

Rice University launched its new Amyloid Mechanism and Disease Center last month, which aims to uncover the molecular origins of Alzheimer’s, Parkinson’s and other amyloid-related diseases.

The center will bring together Rice faculty in chemistry, biophysics, cell biology and biochemistry to study how protein aggregates called amyloids form, spread and harm brain cells. It will serve as the neuroscience branch of the Rice Brain Institute, which was also recently established.

The team will work to ultimately increase its understanding of amyloid processes and will collaborate with the Texas Medical Center to turn lab discoveries into real progress for patients. It will hold its launch event on Jan. 21, 2026, and hopes to eventually be a launchpad for future external research funding.

The new hub will be led by Pernilla Wittung-Stafshed, a Rice biophysicist and the Charles W. Duncan Jr.-Welch Chair in Chemistry.

“To make a real difference, we have to go all the way and find a cure,” Wittung-Stafshede said in a news release. “At Rice, with the Amyloid Mechanism and Disease Center as a catalyst, we have the people and ideas to open new doors toward solutions.”

Wittung-Stafshede, who was recruited to Rice through a Cancer Prevention and Research Institute of Texas grant this summer, has led pioneering work on how metal-binding proteins impact neurodegenerative disorders, including Alzheimer’s and Parkinson’s diseases. Her most recent study, published in Advanced Science, suggests a new way of understanding how amyloids may harm cells and consume the brain’s energy molecule, ATP.

According to Alzheimer’s Disease International, neurodegenerative disease cases could reach around 78 million by 2030 and 139 million by 2050. Wittung-Stafshede’s father died of dementia several years ago.

“This is close to my heart,” Wittung-Stafshede added in the news release. “Neurodegenerative diseases such as dementia, Alzheimer’s and Parkinson’s are on the rise as people live longer, and age is the largest risk factor. It affects everyone.”
