Texas appears in the middle of the pack in a new ranking of the best states for sustainable development.

SmileHub, a nonprofit that rates charities, examined 20 key metrics to create its list of the best states for sustainable development. Among the metrics it studied were the share of urban tree cover, green buildings per capita and clean energy jobs per capita. Once SmileHub crunched all the numbers, it put Texas in 24th place — one notch above average.

The United Nations defines sustainable development as “meeting present needs without compromising the chances of future generations to meet their needs.”

Here’s how Texas fared in several of SmileHub’s ranking categories:

No. 2 for water efficiency and sustainability
No. 7 for presence of wastewater reuse initiatives
No. 18 for environmental protection charities per capita
No. 25 for green buildings per capita
No. 34 for clean energy jobs per capita
No. 34 for industrial toxins per square mile
No. 38 for share of tree cover in urban areas

California leads the SmileHub list, followed by Vermont, Massachusetts, Oregon and Maryland.

When it comes to water, a 2024 report commissioned by Texas 2036, a nonpartisan think tank, recommends that Texas invest $154 billion over the next 50 years in new water supply and infrastructure to support sustainable growth, according to the Greater Houston Partnership.

“The report underscores a stark reality: a comprehensive, sustainable funding strategy for water is necessary to keep Texas economically resilient and competitive,” the partnership says.

Houston-based clean energy site developer raises $300M to decarbonize big tech projects

seeing green

Houston energy executives have started a new company dedicated to developing clean-powered infrastructure for the large electric loads.

Cloverleaf Infrastructure, dually headquartered in Houston and Seattle, Washington, announced its launch and $300 million raised from NGP and Sandbrook Capital, two private equity firms. The company's management team also invested in the company.

As emerging technology continues to grow electricity load demand, Cloverleaf has identified an opportunity to develop large-scale digital infrastructure sites powered by low-carbon electricity.

"The rapid growth in demand for electricity to power cloud computing and artificial intelligence poses a major climate risk if fueled by high-emission fossil fuels," David Berry, Cloverleaf's CEO, says in a news release. "However, it's also a major opportunity to catalyze the modernization of the US grid and the transition to a smarter and more sustainable electricity system through a novel approach to development.

"Cloverleaf is committed to making this vision a reality with the support of leading climate investors like Sandbrook and NGP."

Berry, who's based in Houston, previously co-founded and served as CFO at ConnectGen and Clean Line Energy Partners, clean energy and transmission developers. Last year, he co-founded Cloverleaf with Seattle-based Brian Janous and CTO Jonathan Abebe, who most recently held a senior role at the United States Department of Energy. Nur Bernhardt, director of Energy Strategy at Microsoft who's also based in Seattle, rounds out the executive team as vice president.

"The large tech companies have become dominant players in the electricity sector, and they are genuinely determined to power their growth with the lowest possible emissions," Janous, who serves as chief commercial officer, says in the release. "Achieving this objective doesn't depend on disruptive new technologies as much as it does on dedicated teams working hand in hand with utility partners to maximize the use of the clean generation, storage, and other technologies we already have."

Cloverleaf will work with regional U.S. utilities and data center operators to provide clean electricity at scale through strategic investments in transmission, grid interconnection, land, onsite power generation, and electricity storage, per the release.

"The sustainable development of digital infrastructure at scale is fundamentally a technical power problem," Alfredo Marti, partner at Sandbrook, adds. "We have witnessed members of the Cloverleaf team effectively address this challenge for many years through a blend of creativity, specialized engineering, a partnership mindset, and astute capital deployment."

Sustainability-focused philanthropy recognizes student innovations, local leaders

EMPOWERING THE TRANSITION

From the moment of arrival at the Puranik Foundation Lotus Innovation Awards, attendees engaged in an experience that stimulated the senses and excited the mind – a precise reflection of the foundation’s approach to a holistic education for future innovators.

The event, held last week at the Post Oak Hotel in Uptown, honored Houston leaders supporting the next generation of aspiring entrepreneurs and celebrated the dedication of high school students dreaming sustainability solutions into reality.

“[These students] have the potential to reach innovative places that none of us can think of because we are so set in our ways,“ says Bhakti Puranik, executive director of Puranik Foundation, just steps from where the students showcased their prototypes to secure the gala’s Fan Favorite award. “They are open-minded and creative and constantly inspired by the community that surrounds us.”

The Energy Project, launched in 2020 by the foundation, supports young minds tackling environmental challenges for sustainable development across five sectors: alternative power generation, sustainable consumption, waste management, urban design, and water sustainability.

Multiple small student teams from across the country met for design thinking lessons before creating prototypes of their own solutions at TXRX Labs. The foundation’s primary sponsor, Worldwide Oilfield Machine, provided mentors and resources to the 25 students in this year’s cohort alongside Rice University.

For the winning team, Refoam Maine, the application of mushroom mycelium in lieu of plastic for floating buoys came from the optimistic minds of Maggie Blood, Olivia Huard, Tula Bradley Prindiville, and Laura Riordan, students of Camden Hills Regional High School near Rockport, Maine.

A close-knit community, Camden Hills has collectively seen thousands of orphaned buoys pile up against their docks and beaches for years. The team plans to use their Lotus Innovation Award grant of $15,000 to get their floats in the water, and is actively working with boatyards, aquaculture farmers, and others to bring that vision to reality this summer.

Cyrus Golshan, Nathaniel Lemon, and Alexander Kristof took home the Fan Favorite Award for their solution Piezot, which harnesses energy from revolutionary piezoelectric tiles that convert pressure into energy and electricity.

The team studies at the Energy Institute High School in Houston and envisions an energy ecosystem that doesn’t rely so heavily on natural forces, but rather on human movement as a means to generate power. Placement of the tiles in high-traffic areas like airports, schools, and shopping centers could mean an exponential growth in power supply created simply by the many feet that pass through these areas every day.

Bobby Tudor, CEO and founder of Artemis Energy Partners, and recipient of the Sustainability Lotus Award from Puranik Foundation, attributes the success of the program to the convergence of expertise, a collaborative ecosystem, and global connectivity available from Houston as part of the burgeoning Energy Transition industry.

“We are the energy capital of the world because we are the intellectual capital of energy,“ says Tudor. “The knowledge, the engineering, the expertise, sits here in a more concentrated way than it sits anywhere else in the world. It is that intellectual capital that will pave the way for us to continue to be the energy capital of the world a decade from now, two decades from now, and five decades from now.”

Additionally, Paula Harris, senior vice president of the Houston Astros Community Affairs and Executive Director for the Astros Foundation, accepted the Education Lotus Award for her continued commitment to advancing STEM education across underserved communities.

For his positive impact on the mental well-being of students, Bradley H. Smith, Ph.D., Professor of Psychological, Health, and Learning Services at the University of Houston School of Psychology, Puranik Foundation honored him with Mindfulness Lotus Award.

Applications for The Energy Project are due by 1 November each fall. In addition to the team competition, next year’s cohort includes an immersive experience in India for holistic learning and leadership development.
