Texas dropped in the rankings on WalletHub's Greenest States 2025 report.

The report, released last month, considered 28 relevant metrics—from air and water quality to the number of alternative fuel stations and green buildings per capita—to call out states doing the best (and worst) jobs of caring for the environment.

Texas came in at No. 42 out of 50, with a total score of 42.54 out of 100. Last year, the Lone Star State ranked No. 38 with a score of 50.40 based on 25 metrics.

Texas' poor ranking was driven by its last-placed ranking, coming in at No. 50, for overall environmental quality. It was tied for No. 45 for air quality and ranked No. 46 for water quality, which helped comprise the overall environmental quality score.

Other metrics fell closer toward the middle of the pack. The state ranked No. 32 for eco-friendly behaviors and No. 39 for climate-change contributions.

California also fell on the annual report. While the state claimed the top spot in 2024, it came in at No. 7 this year. Vermont, which came in second in 2024, was named the greenest state in 2025.

Hawaii, which didn't crack the top five last year, was ranked No. 2 on the 2025 report. New York, Maryland and Maine rounded out the top five this year.

West Virginia was the country's least green state again this year, followed by Louisiana, Kentucky, Alabama and Mississippi.

The report also showed that Democrat-led states ranked around No. 12 on average, whereas Republican states fell at around No. 33.

While the WalletHub report seems bleak for Texas, others have shown more positive signs for the state. Texas was ranked slightly above average in a recent ranking of the best states for sustainable development. A recently released U.S. Energy Storage Monitor shows that Texas led all states and surpassed California in the fourth quarter of 2024 by installing 1.2 gigawatts of utility-scale energy storage for solar and wind power.

Still, WalletHub also recently ranked Houston No. 98 out of 100 of the largest cities on its Greenest Cities in America report. Read more here.

What to know about the Houston pipeline fire — how it started, pollution impact, and more

latest update

A pipeline fire that forced hundreds of people to flee their homes in the Houston suburbs burned for a third day Wednesday, with officials saying they don't expect it to be extinguished until sometime Thursday evening.

Officials said residents who had to evacuate would be allowed to return to their homes starting Wednesday evening.

Authorities have offered few details about what prompted the driver of an SUV to hit an aboveground valve on the pipeline on Monday, sparking the blaze.

Here are some things to know about the situation with the pipeline fire:

What caused the fire?

Officials say the underground pipeline, which runs under high-voltage power lines in a grassy corridor between a Walmart and a residential neighborhood in Deer Park, was damaged when the SUV driver left the store's parking lot, entered the wide grassy area and went through a fence surrounding the valve equipment.

Authorities have offered few details on what caused the vehicle to hit the pipeline valve, the identity of the driver or what happened to them. The pipeline company on Wednesday called it an accident. Deer Park officials said preliminary investigations by police and FBI agents found no evidence of a terrorist attack.

Deer Park police won't be able to reach the burned-out vehicle until the flame has been extinguished. Once the area is safe, the department will be able to continue its investigation and confirm specifics, city spokesperson Kaitlyn Bluejacket said in an email Wednesday.

The valve equipment appears to have been protected by a chain-link fence topped with barbed wire. The pipeline's operator has not responded to questions about any other safety protections that were in place.

Who is responsible for the pipeline?

Energy Transfer is the Dallas-based owner of the pipeline, a 20-inch-wide (50-centemeter-wide) conduit that runs for miles through the Houston area.

It carries natural gas liquids through the suburbs of Deer Park and La Porte, both of which are southeast of Houston. Energy Transfer said the fire had diminished overnight and was continuing to “safely burn itself out” on Wednesday.

Energy Transfer also built the Dakota Access Pipeline, which has been at the center of protests and legal battles. The company’s executive chairman, Kelcy Warren, has given millions of dollars in campaign contributions to Republican Texas Gov. Greg Abbott.

What's being done to extinguish the fire?

Energy Transfer said its crews were working Wednesday to install specialized isolation equipment on both sides of the damaged section that will help extinguish the fire.

Once the equipment is installed, which could take several hours of welding, the isolated section of the pipeline will be purged with nitrogen, which will extinguish the fire, company and local officials said. After that, damaged components can be repaired.

“The safest way to manage this process is to let the products burn off,” Energy Transfer said.

Late Wednesday afternoon, Deer Park officials said repair work on the pipeline to help speed up the process to put out the fire wasn't expected to be completed until 6 p.m. on Thursday. Once finished, the fire was anticipated to be extinguished within two to three hours.

How have residents been impacted?

Authorities evacuated nearly 1,000 homes at one point and ordered people in nearby schools to shelter in place. Officials said that starting at 6 p.m. on Wednesday, residents in Deer Park and La Porte who had to evacuate would be allowed to return to their homes. A portion of a highway near the pipeline would remain closed, officials said.

Hundreds of customers lost power. Officials said Wednesday afternoon that only two customers remained without electricity in the Deer Park and La Porte area. Repairs to all of the power distribution lines affected by the fire had been completed.

Deer Park's statement said Energy Transfer was “prioritizing the safety of the community and environment as it implements its emergency response plan.”

“We appreciate the patience and understanding of all residents during this ongoing situation,” Deer Park officials said.

By late Tuesday, about 400 evacuees remained, and some expressed frustration over being forced to quickly flee and not being given any timeline for when they will be able to return.

“We literally walked out with the clothes on our backs, the pets, and just left the neighborhood with no idea where we were going,” said Kristina Reff, who lives near the fire. “That was frustrating.”

What about pollution from the fire?

Energy Transfer and Harris County officials have said that air quality monitoring shows no immediate risk to individuals, despite the huge tower of billowing flame that shot hundreds of feet into the air, creating thick black smoke that hovered over the area.

Houston is the nation’s petrochemical heartland and is home to a cluster of refineries and plants and thousands of miles of pipelines. Explosions and fires are a familiar sight, and some have been deadly, raising recurring questions about industry efforts to protect the public and the environment.

Artist collective brings carbon-absorbing murals to Houston

seeing green

Anthony Rose, the CEO of creative agency United By Design, is on a mission to brighten Houston’s urban spaces and improve the city’s air quality one carbon-absorbing mural at a time.

Rose originally founded United By Design, or UXD, in 2019 to connect muralists like himself and commercial businesses seeking to beautify their spaces and form brand identities. After creating vibrant murals for Lockhart Elementary School, the Houston Astros, and Smoothie King, Rose expanded UXD’s vision to include environmental sustainability in their artistic collaborations in 2022.

“This city’s vibrant art scene and growing focus on sustainability makes it an ideal location for our projects,” Rose says. “We’re not just creating eco-friendly murals, we’re reimagining how art can actively contribute to environmental solutions.”

In search of ecologically-conscious paints, Rose formed a partnership with Spain-based, natural paint company Graphenstone. Rose says he was drawn to the company’s eponymous Graphenstone coating because of its nontoxic ingredients and exclusively uses the product for UXD’s carbon-absorbing murals.

The Graphenstone coating consists of a limestone base which goes through a process called photocatalysis, during which carbon dioxide from the atmosphere is absorbed into the surface, and is then sealed in with graphene, a thin layer of carbon atoms. The murals absorb carbon dioxide throughout the coat’s drying process which typically takes 30 days.

“Each of our murals absorbs about 1600 grams of CO2 during that curing process which is the equivalent daily absorption of about 33 growing trees,” Rose explains.

UXD’s largest carbon-absorbing mural to date is a floor-to-ceiling panorama in downtown Houston’s historic Mellie Esperson building, home to the company’s new creative hub. Painted by Houston-born artist Emily Ding, the mural is a tribute to the establishment’s namesake: an innovative, early 20th century entrepreneur who constructed the opulent building.

Rose says UXD plans to expand their carbon-absorbing murals project in collaboration with more local artists and establishments, while creating an artist-in-residency program themed around sustainability. Though Rose acknowledges in the grand scheme of carbon pollution these murals are not a silver bullet, he says the non-toxic paints are encouraging conversations about how artists can be conservation-minded.

“We’re trying to figure out how art as a messaging tool can help break down scientific data, a language not many people practice daily, can break down barriers and help bridge the gap to a more intuitive knowledge of sustainability,” Rose says. “We’re bringing the community together, helping them feel empowered, and giving them actionable information to help them live more sustainable lives.”

Houston lands on the wrong end of national pollution report

big yikes

Houston just made a list that no one wants it to be on.

Data compiled by the National Public Utilities Council ranks Houston as the 15th most polluted city in the U.S. No other Texas city appears in the ranking. Three California cities — Bakersfield, Visalia, and Fresno — took the top three spots.

The ranking considers a city’s average volume of fine particulate matter in the air per year. Fine particulate matter (formally known as PM2.5) includes soot, soil dust, and sulphates.

The council based its ranking on the average annual concentration of PM2.5 as measured in micrograms per cubic meter of air, known as µg/m3. The ranking lists Houston’s average annual µg/m3 as 11.4. The World Health Organization (WHO) recommends a top µg/m3 of 5, while the American Lung Association sets 9 µg/m as an average annual guideline.

A report released in 2024 by Smart Survey found that the Houston area had just 38 days of good air quality the previous year.

“Most of Houston’s air pollution comes from industrial sources and diesel engines, although sources as diverse as school buses and meat cooking also contribute to … the problem,” the nonprofit Air Alliance Houston says.

The U.S. Environmental Protection Agency says PM2.5 poses “the greatest risk to health” of any particulate matter. Among other health issues, fine particulate matter contributes to cardiovascular disease, lung cancer, and chronic pulmonary disease.

Among the sources of PM2.5 are wildfires, wood-burning stoves, and coal-fired plants, according to the American Lung Association.

The WHO says air pollution causes 7 million deaths annually and may cost the global economy $18 trillion to 25 trillion by 2060. With 70 percent of the population expected to live in urban centers by mid-century, cities are at the forefront of efforts to reduce pollution, according to National Public Utilities Council.

Here's how Texas ranks among the greenest states

zooming in

Turns out — Texas might not be as green as you thought.

A new report from WalletHub looked at 25 key metrics — from green buildings per capita to energy consumption from renewable resources — to evaluate the current health of states' environment and residents’ environmental-friendliness. Texas ranked No. 38, meaning it was the thirteenth least green state, only scoring 50.40 points out of 100.

“It’s important for every American to do their part to support greener living and protect our environment. However, it’s much easier being green in some states than others," writes Cassandra Happe, a WalletHub Analyst, in the report. "For example, if a state doesn’t have a great infrastructure for alternative-fuel vehicles, it becomes much harder for residents to adopt that technology. Living in a green state is also very beneficial for the health of you and your family, as you benefit from better air, soil and water quality.”

Here's how Texas ranked among a few of the key metrics:

  • No. 35 for air quality
  • No. 38 for soil quality
  • No. 38 for water quality
  • No. 26 for LEED-certified buildings per capita
  • No. 32 for percent of renewable energy consumption
  • No. 45 for energy consumption per capita
  • No. 38 for gasoline consumption (in gallons) per capita
Despite Texas' solar energy generation surpassed the output by coal last month, according to a report from the Institute For Energy Economics and Financial Analysis, the Lone Star State has room for improvement.
California was ranked as the greenest state, with Vermont, New York, Maryland, and Washington, respectively, rounding out the top five. The country's least green state is West Virginia, followed by Louisiana, Alabama, Mississippi, and Kentucky.

The report also zeroed in on how politics play into a state's climate system. Democrat-led states ranked around No. 15 on average, whereas Republican states fell at around No. 36.

Expert: How technology is transforming energy education and powering young minds

Guest Column

In today’s ever-changing digital world, the way we teach kids about science is rapidly transforming. Energy education, specifically, is expanding and contributing to the STEM landscape significantly. Helping children understand where energy comes from, how we use it in our everyday lives and how it affects our planet is critical to sparking early interest in STEM learning and inspiring potential careers in the energy industry.

Thanks to new technology and the power of artificial intelligence, we are better equipped to explain these complex ideas in fun, interactive and easy-to-understand ways.

The Role of Educational Technology in Classrooms

Traditional teaching methods can struggle to connect scientific concepts to students’ everyday experiences. A 2023 study found that technology not only makes learning more engaging and enjoyable but also encourages students to invest more effort in their studies over time.

Tools like tablets, smartboards, interactive simulations and gamified learning apps allow students to visualize energy systems, conduct virtual experiments and explore dynamic models that demonstrate how energy flows through different systems.

For example, virtual labs allow students to simulate the installation of solar panels or observe how wind turbines convert kinetic energy into electricity, all without leaving the classroom. These digital tools transform abstract theories into concrete, hands-on experiences, making it easier for students to understand and retain core principles of energy science.

Gamified learning has also become increasingly popular in K–12 classrooms because it engages students by meeting them where they are through interactive, game-like experiences. By incorporating familiar motivators such as points, levels, rewards and challenges, it taps into the same engagement techniques students encounter in video games and apps outside the classroom.

In an era when competition for students’ attention is higher than ever, more educators are turning to gamification because it works; it transforms passive learning into an active, student-centered experience, helping learners stay focused and motivated.

When applied to energy education, gamification can be especially powerful. Educational games that task students with managing a virtual city, designing energy-efficient systems or balancing an energy budget help build valuable real-world skills like problem-solving and systems thinking. Most importantly, they keep students engaged and make learning about energy meaningful.

Equity and Access in Educational Technology

While technology and AI offer immense potential to transform energy education, it is crucial to address the digital divide that exists across different schools and communities. Not all students have equal access to the devices, software or reliable internet connectivity needed to benefit from these innovative learning tools.

Bridging this gap requires collaborative efforts through public-private partnerships, targeted grants and community-driven educational outreach programs. These initiatives play a vital role in ensuring that every student, regardless of socioeconomic background or geographic location, has the opportunity to engage with tech-driven energy education.

Organizations like the Energy Education Foundation are taking meaningful steps in this direction. This fall, the nonprofit is launching EnergyXP, an innovative, mobile STEM learning experience designed for middle school students. The program offers 16 interactive, hands-on, and digital activities aligned with the Next Generation Science Standards, and is provided free of charge to participating schools. Through EnergyXP, students explore diverse energy concepts while building curiosity, collaboration and critical thinking skills. The program links classroom learning to real-world applications, helping students see the role of energy in their daily lives and sparking interest in STEM careers.

Other promising initiatives such as community tech hubs, low connectivity learning platforms, school-device loan programs and subsidized broadband options also support increased access to digital education. In Harris County, the Commissioners Court recently voted unanimously to create the Harris County Broadband Task Force with the aim of expanding internet access and affordability and addressing the growing digital literacy demands in the region. Additionally, Compudopt, a partner of the Energy Education Foundation, is another valuable resource for the Houston-area community. Its programs work to eliminate barriers to computer access, build technical and digital literacy skills, offer no- or low-cost high-speed internet options and support the long-term success of youth and their communities.

By supporting programs and organizations that decrease the digital divide, we can ensure that all students have access to engaging, technology-driven energy education. Providing young learners with the tools to explore, innovate and connect with the energy systems that power their world is key to building a more diverse, inclusive energy workforce for the future.

AI is Transforming the Energy Landscape

Students who utilize technology and AI in the classroom will be better equipped for the energy jobs of the future. As the energy sector continues to evolve, AI is becoming an essential tool for addressing complex challenges from optimizing energy production and distribution to accelerating innovation and improving system reliability.

By exposing students to AI-driven learning experiences early on, we can help them build the skills needed to understand and contribute to emerging technologies such as smart grids, predictive maintenance, renewable energy forecasting and energy storage optimization. These technologies are already shaping the future of how we produce, store and consume energy.

Through hands-on engagement with AI-powered simulations, data analysis tools and problem-solving scenarios, students are learning how to lead in a tech-driven, sustainable energy future.

As the world transitions toward more technology-driven energy systems, the importance of early, engaging and equitable energy education has never been more critical. Through the integration of technology, gamified learning and AI in the classroom, we can make science more accessible and empower students with the knowledge and skills they need to shape the future. Programs like EnergyXP demonstrate how innovation in education can bridge opportunity gaps, spark curiosity and lay the groundwork for a more inclusive and forward-thinking energy workforce. The investments we make in today’s classrooms will determine the energy leaders of tomorrow.
