Houston, often dubbed the “Energy Capital of the World,” is at a pivotal moment in its history. Known for its vast oil and gas reserves, the city is now embracing a new role as a leader in the clean energy transition. This shift is not just about adopting new technologies but also about creatively repurposing existing infrastructure to support sustainable energy solutions.

Houston’s offshore oil wells, many of which are old or abandoned, present a significant opportunity for carbon capture. By repurposing these wells, we can sequester carbon dioxide, reducing greenhouse gas emissions and mitigating climate change. This approach not only utilizes existing infrastructure but also provides a cost-effective solution for carbon management. According to the Greater Houston Partnership, initiatives like these are crucial as Houston aims to lower its climate-changing greenhouse gas emissions. Exxon estimates that just their proposed CCS hub could capture and store 50 million metric tons of CO2 annually by 2030 and 100 million metric tons by 2040.

The proximity of abandoned offshore platforms to the coast makes them ideal candidates for renewable energy substations. These platforms can be transformed into hubs for wind, solar or tidal energy, facilitating the integration of renewable energy into the grid. This repurposing not only maximizes the use of existing structures but also minimizes environmental disruption.

Decommissioned pipelines, which are already in place, offer a ready-made solution for routing renewable energy cables. By using these existing rights of way, Houston can avoid disturbing additional seafloor and reduce the environmental impact of new cable installations. This strategy ensures a smoother transition to renewable energy infrastructure. The U.S. Energy Information Administration notes that Texas, including Houston, leads the nation in wind-generated electricity, highlighting the potential for further renewable energy development.

Onshore oil and gas facilities in Houston also hold potential for clean energy repurposing. Wells that were drilled but never used for oil or gas can be adapted for geological thermal energy storage. This process involves storing excess renewable energy in the form of heat, which can be retrieved when needed, providing a reliable and sustainable energy source. This innovative use of existing wells aligns with Houston’s broader energy transition strategy, which aims to leverage the city’s industrial expertise for a low-carbon future.

Once the land has been remediated, old and abandoned oil fields can be converted into solar farms. This transformation not only provides a new use for previously contaminated land but also contributes to the generation of clean, renewable energy. Solar farms on these sites can help meet Houston’s energy needs while supporting environmental restoration. The Environmental Protection Agency in recent years recognized Houston as the top city in the U.S. for green energy usage, with annual green power usage topping 1 billion kilowatt-hours in 2021.

Houston’s journey towards a clean energy future is a testament to the power of innovation and adaptability. By repurposing existing infrastructure, we can create a sustainable energy landscape that honors the city’s industrial past while paving the way for a greener tomorrow. These strategies highlight the potential for Houston to lead in the clean energy transition, setting an example for cities worldwide.

Texas expert: Energy reliability and climate sustainability are not mutually exclusive

Guest Column

It's no secret that Texas has long been a leader in energy production, but it may surprise you to learn that Texas leads the nation in wind-powered generation, producing 28 percent of all US wind-powered electricity in 2019.

We're not just producing a lot of renewable energy, we're increasingly consuming it.

Contrary to the caricaturistic portrayal of Texans in mainstream culture, a recent study by the University of Houston revealed that 4 out of 5 Texans believe the climate crisis is real.

In an effort to reduce their carbon footprint, more and more households are making the decision to switch to 100 percent renewable energy. And this adoption isn't isolated to core urban areas. We're witnessing a diverse spread in smaller, more rural markets.

These reasons and more are why Bulb, one of Europe's fastest growing company that provides 100 percent renewable energy, chose Texas as its first home in the U.S. Less than a year after launching here, it's safe to say we made the right choice as we're experiencing even faster growth in Texas than we did in our early stages in the United Kingdom.

One of the many reasons Texans have rapidly adopted our simpler, cheaper and greener energy is because they no longer have to choose between being budget and climate conscious. Sadly, the progress the state has made could be knocked back following the recent winter storm.

After the nation witnessed Texas' massive outages during the winter storm, our state leaders understandably feel the pressure to "do something," quickly.

We share our leaders' determination in avoiding another crisis of this magnitude, but we fear that Texas may be heading in the wrong direction. In the mad rush to avoid another catastrophe, some regulators and politicians wrongly and disproportionately blamed renewable energy sources for the outages.

Numerous media outlets and energy experts have overwhelmingly refuted these claims. An AP fact check described the efforts to blame renewable energy sources as "false narratives." And, they're not alone in their conclusion.

According to Reuters' fact check, "These claims are misleading, as they shift blame for the crisis away from what appears, so far, to be the root cause...The state's woes mainly stem from issues surrounding its independent power grid. The cold weather affected all fuel types, not just renewables."

Determining what went wrong isn't a blame game. A proper diagnosis is essential to any problem solving. And a failure to conduct a thorough analysis could have serious consequences. Currently, a number of legislative solutions are floating around the state Capitol that would shift the blame and consequences to renewable energy.

These proposals would increase the financial burden on Texas consumers, many of whom are still recovering from the storm, and hamper new investments in renewable energy. Additionally, and perhaps even more concerning, they don't adequately address the root cause of the winter storm energy crisis, further exposing Texans to another meltdown.

Texas' leadership on renewable energy production is no small feat, and it didn't happen by chance. For two decades, our lawmakers have made strategic decisions that led to the advancement of renewable energy production, and it has paid dividends in terms of jobs, economic growth, energy reliability, sustainability and even the state's reputation.

We are at a critical juncture, but Texas doesn't have to choose between reliability, affordability and sustainability. We can offer reliable energy and green energy, stop another crisis before it happens again and move forward with renewable energy investments.

Continuing to promote policies that pushed Texas to its leadership position will unleash even more investments and innovation, which is good for Texas, good for Texans and good for the planet.

As we observe Earth Day, we would urge our leaders to consider the possibilities. Rather than turn the clock back, let's use this storm as an opportunity to innovate further.

New report lands Texas among 10 worst states for the environment

Not so green

Everything is bigger in Texas, even the negative impact it has on the environment, a new study finds.

Ahead of Earth Day (April 22), personal finance site WalletHub analyzed all 50 states, looking at 27 metrics across three categories: environmental quality, eco-friendly behaviors, and climate-change contributions.

Texas' overall ranking is an abysmal No. 41, making it one of the least green places in America.

The Lone Star State comes in at No. 48 in environmental quality, No. 28 in eco-friendly behaviors, and No. 37 in climate-change contributions. Under climate-change contributions, WalletHub analyzed carbon-dioxide, methane, nitrous-oxide, and fluorinated greenhouse-gas emissions per capita. The higher the number, the worse a state performs in that category.

Despite an overall poor showing, Texas claims a few top spots in individual metrics, performing best in renewable portfolio standards (No. 1), states with electronic waste recycling programs (No. 1), and corporate clean energy procurement index score (No. 5). On the other side of the spectrum, Texas performs worst in the number of alternative-fuel stations per capita (No. 40), air quality (No. 41), water quality (No. 44), and energy consumption per capita (No. 45).

So why exactly is this a WalletHub story? What does this have to do with your money?

"Eco-friendliness and personal finance are related," the report says. "Our environmental and financial needs are the same in many areas: providing ourselves with sustainable, clean drinking water and food, for example. We also spend money through our own consumption and taxes in support of environmental security."

Vermont ranks first in environmentally friendliness, landing at No. 1 in environmental quality, No. 3 in eco-friendly behaviors, and No. 25 climate-change contributions.

Eight states have worse records than Texas: Oklahoma, Mississippi, Arkansas, Alabama, North Dakota, Wyoming, Kentucky, West Virginia, and Louisiana.

While not so green right now, Texas has made great strides in wind energy in recent years. The American Wind Energy Association's annual report for 2018 shows the Lone Star State is home to roughly one-fourth of all U.S. wind power production. If Texas were a country, the wind energy group says, it would rank fifth in the world for wind power capacity, with nearly 25,000 megawatts installed. And with nearly 7,000 megawatts of wind energy projects under construction or development at the end of 2018, Texas is adding more wind energy capacity than what all but two other states actually have installed.

Starbucks brews up solar energy initiative across Houston and Texas

Green coffee

Coffee shop chain Starbucks is plugging into Texas' solar energy industry in a big way.

Two 10-megawatt solar farms in Texas owned by Cypress Creek Renewables LLC are providing enough energy for the equivalent of 360 Starbuck stores, including locations in Houston, Humble, Katy, and Spring. Separately, Starbucks has invested in six other Texas solar farms owned by Cypress Creek, representing 50 megawatts of solar energy; Santa Monica, California-based Cypress Creek is selling that power to other customers.

Three of the eight solar farms in the Texas portfolio are just outside the Houston metro area. One is in the Fort Bend County town of Beasley, while two of the projects are in Wallis and Wharton.

Starbucks already relies on a North Carolina solar farm equipped with 149,000 panels to deliver solar energy equivalent to powering 600 Starbucks stores in North Carolina, Delaware, Kentucky, Maryland, Virginia, West Virginia, and Washington, D.C.

"Our long-standing commitment to renewable energy supports our greener-retail initiative and demonstrates our aspiration to sustainable coffee, served sustainably," Rebecca Zimmer, Starbucks' director of global environmental impact, says in an April 15 release about its solar investment in Texas. "Now, we are investing in new, renewable energy projects in our store communities, which we know is something our partners and customers can appreciate for their local economy and for the environment."

The solar commitment in Texas aligns with Starbucks' goal of designing, building, and operating 10,000 "greener" company-owned stores around the world by 2025. The Seattle-based retailer expects this initiative — whose features include renewable energy, energy efficiency, and waste reduction — to cut $50 million in utility costs over the next 10 years.

U.S. Bank's community development division teamed up with Starbucks and Cypress Creek on the Texas solar farms. Chris Roetheli, a business development officer at U.S. Bank, says solar tax equity investments like those undertaken by Starbucks are growing in popularity among non-traditional investors.

"Starbucks is taking a unique approach — investing in solar farms regionally to support a specific group of its stores," Roetheli says in the announcement of the solar collaboration. "This is a new concept, and one that I think other companies are watching and may follow. It's an interesting model that allows them to talk specifically about the impact of their investments."

Starbucks' investment comes as Texas' stature in the solar energy sector keeps rising, along with the state's role in the wind energy industry.

According to the Solar Energy Industries Association, more than 2,900 megawatts of solar capacity are installed in Texas. That's enough energy to power nearly 350,000 homes. Among the states, Texas ranks fifth for the amount of installed solar capacity.

Solar investment in Texas exceeds $4.5 billion, with about 650 solar companies operating statewide, the association says. The solar energy industry employs more than 13,000 full-time and part-time workers in Texas, according to the Texas Solar Power Association.

With more than 4 gigawatts (over 7,000 megawatts) of solar capacity expected to be added in Texas over the next five years, the national solar association reported in 2018 that "Texas is poised to become a nationwide leader in solar energy … ."

As it stands now, though, solar supplies less than 1 percent of Texas' electricity.

A 2018 state-by-state report card for friendliness toward solar power assigned a "C" to Texas, putting it in 34th place among the states.

The report card, released by SolarPowerRocks.com, lauds the backing of big Texas cities like Houston, Austin, Dallas, and San Antonio in encouraging residential solar installations.

However, the report card adds, outlying areas in Texas lag their urban counterparts in support of residential solar, "and we'd like lawmakers here to codify more protections and goals for solar adoption, but in the most populous areas, the Lone Star [State] shines."

Houston medtech startup clears FDA approval for new surgical tool

precision surgery

Houston-based Prana Surgical will soon bring a new electrosurgical tool to operating rooms around the country. The Prana System officially cleared U.S. Food and Drug Administration (FDA) approval earlier this month.

"Receiving FDA clearance for the Prana System represents a defining milestone for our company," Joanna Nathan, CEO and co-founder of Prana Surgical, said in a news release. "Surgeons today are increasingly focused on achieving precise outcomes while minimizing disruption to healthy tissue. The Prana System was designed to support that shift by integrating targeting and excision into a single, streamlined tool."

Prana Surgical began as Prana Thoracic in 2022. Back then, the company primarily focused on developing screening tools for lung cancer diagnosis. It raised $6 million in series A funding rounds in 2023 and 2024 before transitioning to broader surgical needs in 2025.

The Prana System is a minimally invasive, image-guided, single-use tissue extraction tool designed to retrieve samples without damaging healthy tissue. The tool is still designed with the respiratory system in mind, helping Prana in the fight against lung cancer and other thoracic diseases.

Reducing the impact of tissue extraction via electrosurgery and enhanced image scanning can significantly reduce complications. The Prana System combines localization and tissue-cutting capabilities in one, which keeps surgeons from having to swap out components during a procedure, making for a smoother process. It can core, cut and feel blood vessels on the way toward the intended target, giving surgeons greater control over tissue preservation.

"Electrosurgery is foundational to modern surgery, but there is still opportunity to improve how energy-based tools are applied in minimally invasive settings," Nathan added. "Our goal is to introduce a new class of image-guided surgical tools that enable more precise intervention across a range of procedures."

The company projects sales of $7.5 billion from the Prana System in the United States, estimating that 2.5 million surgical modules will be able to use the new tool. While starting out focused on biopsies, the company plans to evolve the system into other procedures, such as ablation, in the future. It is also planning for a controlled U.S. clinical rollout as it moves toward commercialization

Texas still ranks as No. 1 in U.S. for inbound moves, but growth dips

by the numbers

Texas continues to be the country’s No. 1 magnet for newcomers from other states, giving a boost to the state’s economy. However, Texas’ appeal weakened in 2024 compared with the previous year, due in large part to spiking home prices.

An analysis of U.S. Census Bureau data by self-storage platform StorageCafe shows Texas saw net interstate migration of 76,000 people in 2024. Texas’ net interstate migration dropped nearly 50 percent from 2023, according to the analysis. Net migration refers to the number of incoming residents minus the number of outgoing residents.

California remained the top source of newcomers for Texas, sending nearly 77,000 residents to the Lone Star State in 2024, the analysis says. Florida ranked second, followed by New York, Colorado and Illinois.

“These trends reveal Texas’ continued pull from both high-cost coastal markets and other large Sun Belt states, resulting in a mix of affordability-driven and job-driven relocation,” StorageCafe says.

Putting a damper on the influx of new residents: a roughly 124 percent surge in Texas home prices over the past decade, according to StorageCafe.

“While the state remains significantly more affordable than California, its top feeder state, the once-wide pricing gap has narrowed,” says StorageCafe. “For many movers, Texas is still a relative bargain, but no longer an undisputed one.”

Nonetheless, Texas keeps attracting young, highly educated people, which bodes well for the state’s long-term economic outlook, StorageCafe says. More than half of new arrivals to Texas in 2024 held at least a bachelor’s degree, and the age of newcomers averaged 32.

Where are most of these young, highly educated newcomers settling?

Lloyd Potter, former Texas state demographer, tells StorageCafe that population growth in Texas is happening most rapidly in suburban “ring counties” at the expense of slowing growth in urban cores. Ring counties are on the outskirts of major metro areas.

“Many people are moving from urban cores to suburban rings seeking lower costs, newer housing, better schools, and more space,” Potter says. “Typically, a move to a suburban county will be within commuting or hybrid‑commuting distance of major metro economies.”

Artemis II makes historic call to space station with help from Houston Mission Control

History in the making

Still aglow from their triumphant lunar flyby, the Artemis II astronauts made more history Tuesday, April 7: calling their friends aboard the International Space Station hundreds of thousands of miles away as they headed home from the moon.

It was the first moonship-to-spaceship radio linkup ever. NASA's Apollo crews had no off-the-planet company back in the 1960s and 1970s, the last time humanity set sail for deep space.

"We have been waiting for this like you can’t imagine,” Artemis II commander Reid Wiseman called out.

For Christina Koch on Artemis II and Jessica Meir aboard the space station, it marked a joyous space reunion despite being 230,000 miles (370,000 kilometers) apart. The two teamed up for the world's first all-female spacewalk in 2019 outside the orbiting lab.

Koch told her “astro-sister” that she'd hoped to meet up with her again in space “but I never thought it would be like this — it's amazing.”

“I'm so happy that we are back in space together,” Meir replied, “even if we are a few miles apart.”

Houston's Mission Control arranged the cosmic chitchat between the four lunar travelers and the space station's three NASA and one French residents.

Koch described being awe-struck by not just the beauty of Earth, “but how much blackness there was around it.”

“It just made it even more special. It truly emphasized how alike we are, how the same thing keeps every single person on planet Earth alive,” she told the space station crew. “The specialness and preciousness of that really is emphasized” when viewing the home planet from the moon.

By late Tuesday afternoon, the Artemis II astronauts had beamed back more than 50 gigabytes' worth of pictures and other data from the previous day's lunar rendezvous, which set a new distance record for humanity. The highlight: an Earthset photo reminiscent of Apollo 8's Earthrise shot from 1968.

"While they are inspirational and, I think, allow all of us to really feel a little bit of what they were feeling, there's also a lot of science hidden inside of those images," said Mission Control's lead lunar scientist Kelsey Young. “The conversations and the science lessons learned are just beginning."

During a debriefing with Young, the astronauts recounted how they spotted a cascade of pinpricks of light on the lunar surface from impacting cosmic debris. The flashes lasted mere milliseconds and coincided by chance with Monday evening's total solar eclipse.

Young said it was too soon to know whether the crew witnessed an actual meteor shower or more random, run-of-the-mill micrometeoroid hits. Either way, there were “audible screams of delight” in the science operations center, she said.

Koch described being awe-struck by not just the beauty of Earth, “but how much blackness there was around it.”

“It just made it even more special. It truly emphasized how alike we are, how the same thing keeps every single person on planet Earth alive,” she told the space station crew. “The specialness and preciousness of that really is emphasized” when viewing the home planet from the moon.

The first lunar explorers since Apollo 17 in 1972, Wiseman and his crew are aiming for a splashdown off the San Diego coast on Friday to wrap up the nearly 10-day test flight. The recovery ship USS John P. Murtha left port Tuesday for the target zone.

It sets the stage for next year's Artemis III, a lunar lander docking demo in orbit around Earth. Artemis IV will follow in 2028 with two astronauts attempting to land near the lunar south pole.

As for the Orion capsule’s pesky potty, Mission Control assured the astronauts that no maintenance was required Tuesday. The toilet has been on-and-off limits to the crew ever since last week’s launch, prompting them to rely on a backup bag-and-funnel system for urinating.

NASA Administrator Jared Isaacman told the crew following the lunar flyby Monday night: “We definitely have to fix some of the plumbing” ahead of the next Artemis mission. Engineers suspect a clogged filter in the overboard flushing system.

Aside from the toilet and other relatively minor matters, the mission has gone well, Isaacman noted at a news conference Tuesday, “but I'll breathe easier when we get through reentry and everybody's under chutes and in the water.”
