While our grid may be showing its age, this is the perfect time to shift from reacting to problems to getting ahead of them.

Did you catch those images of idle generators that CenterPoint had on standby during Hurricane Beryl? With over 2 million people in the Houston area left in the dark, many were wondering, "if the generators are ready, why didn’t they get used?" It seems like power outages are becoming just as common as the severe storms themselves.

But as Ken Medlock, Senior Director of the Baker Institute Center for Energy Studies (CES) explains, it's not a simple fix. The outages during Hurricane Beryl were different from what we saw during Winter Storm Uri. This time, with so many poles and wires down, those generators couldn’t be put to use. It’s a reminder that each storm brings its own set of challenges, and there’s no one-size-fits-all solution when it comes to keeping the lights on. While extreme weather is one of the leading threats to our electric grid, it's certainly not the only one adding strain on our power infrastructure.

The rapid rise of artificial intelligence (AI) and electric vehicles (EVs) is transforming the way we live, work, and move. Beneath the surface of these technological marvels lies a challenge that could define the future of our energy infrastructure: they all depend on our electrical grid. As AI-powered data centers and a growing fleet of EVs demand more power than ever before, our grid—already under pressure from extreme weather events and an increasing reliance on renewable energy—faces a critical test. The question goes beyond whether our grid can keep up, but rather focuses on how we can ensure it evolves to support the innovations of tomorrow without compromising reliability today. The intersection of these emerging technologies with our aging energy infrastructure poses a dilemma that policymakers, industry leaders, and consumers must address.

Julie Cohn, Nonresident Fellow at the Center for Energy Studies at the Baker Institute for Public Policy, presents several key findings and recommendations to address concerns about the reliability of the Texas energy grid in her Energy Insight. She suggests there’s at least six developments unfolding that will affect the reliability of the Texas Interconnected System, operated by the Electric Reliability Council of Texas (ERCOT) and the regional distribution networks operated by regulated utilities.

Let’s dig deeper into some of these issues:

AI

AI requires substantial computational power, particularly in data centers that house servers processing vast amounts of data. These data centers consume large amounts of electricity, putting additional strain on the grid.

According to McKinsey & Company, a single hyperscale data center can consume as much electricity as 80,000 homes combined. In 2022, data centers consumed about 200 terawatt-hours (TWh), close to 4 percent, of the total electricity used in the United States and approximately 460 TWh globally. That’s nearly the consumption of the entire State of Texas, which consumed approximately 475.4 TWh of electricity in the same year. However, this percentage is expected to increase significantly as demand for data processing and storage continues to grow. In 2026, data centers are expected to account for 6 percent, almost 260 TWh, of total electricity demand in the U.S.

EVs

According to the Texas Department of Motor Vehicles, approximately 170,000 EVs have been registered across the state of Texas as of 2023, with Texas receiving $408 million in funding to expand its EV charging network. As Cohn suggests, a central question remains: Where will these emerging economic drivers for Texas, such as EVs and AI, obtain their electric power?

EVs draw power from the grid every time they’re plugged in to charge. This may come as a shock to some, but “the thing that’s recharging EV batteries in ERCOT right now, is natural gas,” says Medlock. And as McKinsey & Company explains, the impact of switching to EVs on reducing greenhouse gas (GHG) emissions will largely depend on how much GHG is produced by the electricity used to charge them. This adds a layer of complexity as regulators look to decarbonize the power sector.

Depending on the charger, a single EV fast charger can pull anywhere from 50 kW to 350 kW of electricity per hour. Now, factor in the constant energy drain from data centers, our growing population using power for homes and businesses, and then account for the sudden impact of severe environmental events—which have increased in frequency and intensity—and it’s clear: Houston… we have a problem.

The Weather Wildcard

Texas is gearing up for its 2025 legislative session on January 14. The state's electricity grid once again stands at the forefront of political discussions. The question is not just whether our power will stay on during the next winter storm or scorching summer heatwave, but whether our approach to grid management is sustainable in the face of mounting challenges. The events of recent years, from Winter Storm Uri to unprecedented heatwaves, have exposed significant vulnerabilities in the Texas electricity grid, and while legislative measures have been taken, they have been largely patchwork solutions.

Winter Storm Uri in 2021 was a wake-up call, but it wasn’t the first or last extreme weather event to test the Texas grid. With deep freezes, scorching summers, and unpredictable storms becoming the norm rather than the exception, it is clear that the grid’s current state is not capable of withstanding these extremes. The measures passed in 2021 and 2023 were steps in the right direction, but they were reactive, not proactive. They focused on strengthening the grid against cold weather, yet extreme heat, a more consistent challenge in Texas, remains a less-addressed threat. The upcoming legislative session must prioritize comprehensive climate resilience strategies that go beyond cold weather prep.

“The planners for the Texas grid have important questions to address regarding anticipated weather extremes: Will there be enough energy? Will power be available when and where it is needed? Is the state prepared for extreme weather events? Are regional distribution utilities prepared for extreme weather events? Texas is not alone in facing these challenges as other states have likewise experienced extremely hot and dry summers, wildfires, polar vortexes, and other weather conditions that have tested their regional power systems,” writes Cohn.

Renewable Energy and Transmission

Texas leads the nation in wind and solar capacity (Map: Energy, Environment, and Policy in the US), however the complexity lies in getting that energy from where it’s produced to where it’s needed. Transmission lines are feeling the pressure, and the grid is struggling to keep pace with the rapid expansion of renewables. In 2005, the Competitive Renewable Energy Zones (CREZ) initiative showed that state intervention could significantly accelerate grid expansion. With renewables continuing to grow, the big question now is whether the state will step up again, or risk allowing progress to stall due to the inadequacy of the infrastructure in place. The legislature has a choice to make: take the lead in this energy transition or face the consequences of not keeping up with the pace of change.

Conclusion

The electrical grid continues to face serious challenges, especially as demand is expected to rise. There is hope, however, as regulators are fully aware of the strain. While our grid may be showing its age, this is the perfect time to shift from reacting to problems to getting ahead of them.

As Cohn puts it, “In the end, successful resolution of the various issues will carry significant benefits for existing Texas industrial, commercial, and residential consumers and have implications for the longer-term economic attractiveness of Texas. Suffice it to say, eyes will be, and should be, on the Texas legislature in the coming session.”

Rice University releases data, analysis on future of global energy

eyes on insights

The Center for Energy Studies at Rice University’s Baker Institute for Public Policy has released a collection of articles addressing the most pressing policy issues in global energy.

The inaugural Energy Insights was supported by ongoing research at CES, with a goal of better understanding the energy landscape over the next few years.

“While no one can predict exactly what comes next, if we are paying attention, the road we travel provides plenty of signposts that can be used to understand the challenges and opportunities ahead,” wrote CES Senior Director Kenneth Medlock.

The articles, which are available online in a 120-page packet, focus on a wide variety of key issues — Texas electricity policy, energy and geopolitics in Eurasia, how the energy transition will affect the Middle East, the growing necessity of minerals and materials, and more.

All in all, the new Energy Insights will look at the ever-changing energy landscape.

“Industrialization, improved living standards, technological and process innovation, and increased mobility of people and goods, to name a few, are all hallmarks of continual energy transition,” Medlock adds. “The process is not done. The past lives on through long-lived legacy infrastructures, and the future evolves most rapidly when it can leverage that legacy. Exactly how though, remains an elusive topic.”

Hobby debuts solar canopy as airport system reaches new sustainability milestone

solar solutions

Houston's William P. Hobby Airport is generating its own clean energy.

Houston Aiports announced that Hobby's red garage is now home to a "solar canopy" that is producing energy at 100 percent capacity to power daily operations. The photovoltaic (PV) solar system generated more than 1.1 gigawatt-hours of electricity in testing, and is expected to produce up to 1 megawatt-hour now that it's operating at full power.

“This project is proof that sustainability can be practical, visible and directly tied to the passenger experience,” Jim Szczesniak, director of aviation for Houston Airports, said in a news release. “Passengers now park under a structure that shields their cars from the Texas sun while generating clean energy that keeps airport operations running efficiently, lowering overall peak demand electrical costs during the day and our carbon footprint. It’s a win for travelers, the city and the planet.”

The project was completed by Texas A&M Engineering Experiment Station (TEES) and CenterPoint Energy. It's part of Houston Airport's efforts to reduce carbon emissions by 40 percent over its 2019 baseline.

In a separate announcement, the airport system also shared that it recently reached Level 3 in the Airports Council International (ACI) Airport Carbon Accreditation program after reducing emissions by 19 percent in three years. This includes reductions at George Bush Intercontinental Airport (IAH), Hobby and Ellington Airport/Houston Spaceport.

The reductions have come from initiatives such as adding electric vehicles to airport fleets, upgrading airfield lighting with LED bulbs, adding smarter power systems to terminals, and improving IAH's central utility plant with more efficient equipment. Additionally, the expansion to Hobby's West Concourse and renovations at IAH Terminal B incorporate cleaner equipment and technology.

According to Houston Airports, from 2019 to 2023:

  • IAH reduced emissions by 17 percent
  • Hobby reduced emissions by 32 percent
  • Ellington Airport reduced emissions by 4 percent

"I see firsthand how vital it is to link infrastructure with sustainability,” Houston City Council Member Twila Carter, chair of the council’s Resilience Committee, said in the release. “Reducing carbon emissions at our airports isn’t just about cleaner travel — it’s about smarter planning, safer communities and building a Houston that can thrive for generations to come.”

Houston Methodist leader on the push for sustainable health care and new local event

Q&A

Every industry can play a role in the energy transition, and Houston Methodist is leading the charge in the health care sector.

Culminating at this week’s inaugural Green ICU Conference, part of Houston Energy and Climate Startup Week, the health care system has spent the last three years taking a closer look at its environmental footprint—and showing other hospital systems and medical organizations how they too can make simple changes to reduce emissions.

The event, held tomorrow, Sept. 17, at TMC Helix Park, will bring together health care professionals, industry leaders, policymakers and innovators to explore solutions for building a more sustainable healthcare system.

In an interview with EnergyCapital, Dr. Faisal N. Masud, medical director of critical care at Houston Methodist and a champion for sustainability efforts across the system, shares the inspiration behind the event and what attendees can expect to take away.

Tell us about how the Green ICU Conference came to be.

Houston Methodist’s inaugural Green ICU conference is about three years in the making. It originated because Houston Methodist recognized the significant impact health care has on sustainability and the lack of similar initiatives in the U.S.

The Center for Critical Care at Houston Methodist launched a sustainability-focused ICU initiative, published a roadmap and became involved in international efforts to develop guidelines that many other organizations now use. Our work led to the creation of the first Green ICU Collaborative in the country, and the Green ICU Conference was established to share best practices and address the global impact of critical care on the environment.

What were some of the biggest takeaways from the collaborative, and how are they represented in this new event?

Through the Green ICU Collaborative, we’ve seen that health care professionals can make a significant impact on sustainability through simple, practical changes, and many solutions can be implemented without major costs or compromising patient care. Additionally, there’s a strong link between environmental stewardship and patient safety and quality. These lessons will be represented in the new Green ICU Conference by showcasing easy-to-adopt best practices, emphasizing the importance of sustainability in daily health care operations, and fostering a sense of shared responsibility among attendees to improve both patient outcomes and environmental impact.

Why are ICUs considered to be such carbon hot spots?

ICUs are considered carbon hot spots because they care for the sickest patients, requiring intensive therapies, numerous medications and a large amount of equipment, such as ventilators and pumps. This makes them the most resource- and energy-intensive areas in a hospital. A single day in the ICU can have a greenhouse gas impact equivalent to driving a car 1,000 kilometers.

The U.S. health care sector is responsible for approximately 8.5 percent of greenhouse gas emissions, and hospitals are the second-most energy-intensive commercial buildings in the country. With the Texas Medical Center being in the heart of Houston, it’s critical that health care organizations play a role in this area.

That’s why the Center for Critical Care launched a system-wide Green ICU Initiative with the Houston Methodist Office of Sustainability to help reduce our carbon impact and waste while continuing to provide unparalleled patient care. Innovation is part of our culture, and that extends into our sustainability efforts. Houston Methodist’s Green ICU initiative is the first-of-its-kind in the U.S.

What efforts has Houston Methodist taken to cut emissions?

The first step to cutting emissions is measuring an organization’s carbon footprint to determine the best path forward. Houston Methodist’s Office of Sustainability has aggregated two years of baseline emissions data pending third-party validation. The hospital has taken several steps to cut emissions, including implementing composting programs, installing solar panels, improving energy utilization and participating in global plastic recycling initiatives. These efforts are part of a broader commitment led by our Office of Sustainability to reduce the hospital’s environmental footprint.

Tell us a little more about the event. Who should attend? What do you expect to be some of the highlights?

The Green ICU Conference, taking place during Houston Energy and Climate Week, is focused on health care sustainability, bringing together health care professionals, engineers, experts and anyone interested in reducing health care’s environmental impact. With participants and speakers from six countries, the conference brings together leading experts who aim to raise awareness, share best practices and offer practical, easy-to-adopt solutions for making health care more sustainable.

Highlights include perspectives from leading voices in health care sustainability, real-world examples of successful sustainability initiatives and opportunities for networking and collaboration. Anyone interested in health care, sustainability,or making a positive impact in their community should consider attending.

And, because of increasing interest, we’ve opened up the opportunity for attendees to join virtually at no cost or in person.

What do you hope attendees take away? What are your major goals for the event?

The main goals of hosting the Green ICU Conference for the first time are to raise awareness about the environmental impact of health care; engage and empower attendees to implement easy, practical sustainability solutions; and foster a sense of shared community and responsibility.

I hope attendees leave the event feeling motivated and equipped to make meaningful changes in their own practices, whether that’s improving patient care, supporting their colleagues, or leaving their organization and environment in a better place for future generations.
