Dozens of Houston college students tackled circular economy challenges, and two came out on top by winning the top award.

University of Houston’s Energy Transition Institute hosted a challenge for students to address the issue of plastic waste and create a real-world circular economy, as over 60 students participated in the inaugural Circular Plastics Challenge.

Six finalist teams presented their solutions at the 2023 Energy Night hosted by the UH Energy Coalition with final pitches ranging from transportation emissions, renewable packaging and sustainable material, drones to limit excess packaging, and more topics aimed to reduce use.

Sarah Grace Kimberly and Emma Nicholas were the challenge winners. The team proposed using a liquid-based membrane filter inserted into household drains to combat microplastics found in common personal care products, such as makeup and hygiene items. The membrane’s function would act as a magnet, which would attract and capture microplastics from wastewater in showers and sinks. Both juniors from the C.T. Bauer College of Business also won the viewer’s choice award from their peers.

“We wanted to provide a simple solution to a growing problem,” Kimberly says in a news release. “Before we did this project, we didn’t know that microplastics existed, let alone in our makeup. I didn’t know I was basically putting plastic on my face every single day and washing it off into our drains. Because it’s an unseen problem, it’s hard to address.”

UH’s ETI is an academic research institute that focuses on advancing environmentally responsible energy efforts.

“If you look at the wide variety of proposals and approaches, you can see the complexity of the problem and all the different things that society must consider to find solutions,” ETI Founding Executive Director Joe Powell says in the release. “I think circularity in plastics and chemicals is as difficult to address as the net-zero issue within the energy sector, if not more. We have a unique opportunity here to tackle both, and it’s really great to see our students thinking ahead.

Other finalists included Wolff Center for Entrepreneurship seniors Nicolas Einarsson, Bennett Mainini, Arianna Chavarria, and Fernanda Ruelas, who secured second place with their renewable packaging company presentation titled “ShipSafe.”

Reverse Logistics — with team members Hasti Seraji, Farzane Ezzati, and Haowei Yang — earned third place for their consumer-driven reverse logistics approach to recycling packaging.

New report predicts major data center boom in Texas by 2028

data analysis

Data centers are proving to be a massive economic force in Texas.

For instance, a new report from clean energy company Bloom Energy predicts Texas will see a 142 percent increase in its market share for data centers from 2025 to 2028. That would be the highest increase of any state.

Bloom Energy expects Texas to exceed 40 gigawatts of data-center capacity by 2028, representing a nearly 30 percent share of the U.S. market. A typical AI data center consumes 1 to 2 gigawatts of energy.

“Data center and AI factory developers can’t afford delays,” Natalie Sunderland, Bloom Energy’s chief marketing officer, said in the report. “Our analysis and survey results show that they’re moving into power‑advantaged regions where capacity can be secured faster — and increasingly designing campuses to operate independently of the grid.”

“The surge in AI demand creates a clear opportunity for states that can adapt to support large-scale AI deployments at speed,” Sunderland adds.

Further evidence of the data center explosion in Texas comes from ConstructConnect, a provider of data and software for contractors and manufacturers. ConstructConnect reported that in the 12-month span through November 2025, data-center construction starts in Texas accounted for $11 billion in spending. At $12.5 billion, only Louisiana surpassed the Texas total.

Capital expenses for U.S. data centers were expected to surpass $425 billion last year, according to ratings agency S&P Global.

ConstructConnect also reports that Texas is among five states collectively grabbing 80 percent of potential data center construction starts. Currently, Texas hosts around 400 data centers, with close to 60 of them in the Houston market.

A large pool of data-center construction spending in Texas is flowing from Google, which announced in November that it would earmark $40 billion for new AI data centers in the state.

“Texas leads in AI and tech innovation,” Gov. Greg Abbott proclaimed when the Google investment was unveiled.

Other studies and reports lay out just how much data centers are influencing economic growth in the Lone Star State:

  • A study by Texas Royalty Brokers indicates Texas leads the U.S. with 17 clusters of AI data centers. The study measured the density of AI data centers by counting the number of graphics processing units (GPUs) installed in those clusters. GPUs are specialized chips built to run AI models and perform complex calculations.
  • Citing data from construction consulting company FMI, The Wall Street Journal reported that spending on construction of data centers is expected to rise 23 percent in 2026 compared with last year. Much of that construction spending will happen in Texas. In the 12 months through November 2025, the average data center cost $597 million, according to ConstructConnect.
  • Data published in 2025 by commercial real estate services company Cushman & Wakefield shows three Texas markets — Austin, Dallas and San Antonio — boast the lowest construction costs for data centers among the 19 U.S. markets that were analyzed. The mid-range of costs in that trio of markets is roughly $10.65 million per megawatt. Houston isn’t included in the data.

Although Houston isn’t cited in the Cushman & Wakefield data, it nonetheless is playing a major role in the data-center boom. Houston-area energy giants Chevron and ExxonMobil are chasing opportunities to supply natural gas as a power source for data centers, for example.

“As Houston rapidly evolves into a hub for AI, cloud computing, and data infrastructure, the city is experiencing a surge in data-center investments driven by its unique position at the intersection of energy, technology, and innovation,” says the Greater Houston Partnership.

Houston-based ENGIE to add new wind and solar projects to Texas grid

coming soon

Houston-based ENGIE North America Inc. has expanded its partnership with Los Angeles-based Ares Infrastructure Opportunities to add 730 megawatts of renewable energy projects to the ERCOT grid.

The new projects will include one wind and two solar projects in Texas.

“The continued growth of our relationship with Ares reflects the strength of ENGIE’s portfolio of assets and our track record of delivering, operating and financing growth in the U.S. despite challenging circumstances,” Dave Carroll, CEO and Chief Renewables Officer of ENGIE North America, said in a news release. “The addition of another 730 MW of generation to our existing relationship reflects the commitment both ENGIE and Ares have to meeting growing demand for power in the U.S. and our willingness to invest in meeting those needs.”

ENGIE has more than 11 gigawatts of renewable energy projects in operation or under construction in the U.S. and Canada, and 52.7 gigawatts worldwide. The company is targeting 95 gigawatts by 2030.

ENGIE launched three new community solar farms in Illinois since December, including the 2.5-megawatt Harmony community solar farm in Lena and the Knox 2A and Knox 2B projects in Galesburg.

The company's 600-megawatt Swenson Ranch Solar project near Abilene, Texas, is expected to go online in 2027 and will provide power for Meta, the parent company of social media platform Facebook. Late last year, ENGIE also signed a nine-year renewable energy supply agreement with AstraZeneca to support the pharmaceutical company’s manufacturing operations from its 114-megawatt Tyson Nick Solar Project in Lamar County, Texas.

Houston geothermal company raises $97M Series B

fresh funding

Houston-based geothermal energy startup Sage Geosystems has closed its Series B fundraising round and plans to use the money to launch its first commercial next-generation geothermal power generation facility.

Ormat Technologies and Carbon Direct Capital co-led the $97 million round, according to a press release from Sage. Existing investors Exa, Nabors, alfa8, Arch Meredith, Abilene Partners, Cubit Capital and Ignis H2 Energy also participated, as well as new investors SiteGround Capital and The UC Berkeley Foundation’s Climate Solutions Fund.

The new geothermal power generation facility will be located at one of Ormat Technologies' existing power plants. The Nevada-based company has geothermal power projects in the U.S. and numerous other countries around the world. The facility will use Sage’s proprietary pressure geothermal technology, which extracts geothermal heat energy from hot dry rock, an abundant geothermal resource.

“Pressure geothermal is designed to be commercial, scalable and deployable almost anywhere,” Cindy Taff, CEO of Sage Geosystems, said in the news release. “This Series B allows us to prove that at commercial scale, reflecting strong conviction from partners who understand both the urgency of energy demand and the criticality of firm power.”

Sage reports that partnering with the Ormat facility will allow it to market and scale up its pressure geothermal technology at a faster rate.

“This investment builds on the strong foundation we’ve established through our commercial agreement and reinforces Ormat’s commitment to accelerating geothermal development,” Doron Blachar, CEO of Ormat Technologies, added in the release. “Sage’s technical expertise and innovative approach are well aligned with Ormat’s strategy to move faster from concept to commercialization. We’re pleased to take this natural next step in a partnership we believe strongly in.”

In 2024, Sage agreed to deliver up to 150 megawatts of new geothermal baseload power to Meta, the parent company of Facebook. At the time, the companies reported that the project's first phase would aim to be operating in 2027.

The company also raised a $17 million Series A, led by Chesapeake Energy Corp., in 2024.
