Houstonians may be feeling blue about a new ranking of the greenest cities in the U.S.

Among the country’s 100 largest cities based on population, Houston ranks 99th across 28 key indicators of “green” living in a new study from personal finance website WalletHub. The only city with a lower ranking is Glendale, Arizona. Last year, Houston landed at No. 98 on the WalletHub list.

“‘Green’ living means a choice to engage in cleaner, more sustainable habits in order to preserve the planet as much as possible,” WalletHub says.

Among the study’s ranking factors are the amount of greenhouse gas emissions per capita, the number of “smart energy” policies, and the presence of “green job” programs.

In the study, Houston received an overall score of 35.64 out of 100. WalletHub put its findings into four buckets, with Houston ranked 100th in the environment and transportation categories, 56th in the lifestyle and policy category, and 52nd in the energy sources category.

In the environment category, Houston has two big strikes against it. The metro area ranks among the 10 worst places for ozone pollution (No. 7) and year-round particle pollution (No. 8), according to the American Lung Association’s 2025 list of the most polluted cities.

In the WalletHub study, San Jose, California, earns the honor of being the country’s greenest city. It’s followed by Washington, D.C.; Oakland, California; Irvine, California; and San Francisco.

“There are plenty of things that individuals can do to adopt a green lifestyle, from recycling to sharing rides to installing solar panels on their homes,” WalletHub analyst Chip Lupo said in the report. “However, living in one of the greenest cities can make it even easier to care for the environment, due to sustainable laws and policies, access to locally grown produce, and infrastructure that allows residents to use vehicles less often. The greenest cities also are better for your health due to superior air and water quality.”

The end of the solar tax credit is not the end of the solar industry. Photo by Kindel Media/Pexels

Texas still has its best solar days ahead of it, even as federal tax credit sunsets

Guest Column

If you follow energy policy, you already know that Congress repealed the 30% residential solar tax credit. This poses a significant challenge for continued growth in the market. It also provides an opportunity for the industry to grow in a smart, consumer-friendly way. That’s why in Texas, the story is what happens next: The state and the market are continuing to make going solar much simpler, better, and cheaper.

Policies are moving in the right direction. For example, starting this month, a bipartisan permitting reform takes effect that will cut red tape for home solar and batteries. It lets licensed third-party professionals review plans and perform inspections, requires agencies to post standardized rules and fees online, and allows homeowners to start work once those third-party approvals are submitted. It also shifts negligence liability to the third-party reviewer, thereby reducing municipal risk while accelerating safe, code-compliant installs. In plain English: fewer bottlenecks, faster installs, and lower “soft costs.”

As a result, Houston is already piloting the National Renewable Energy Lab’s free SolarAPP+ to auto-approve standard solar designs, which cuts roughly 12 days from typical timelines. Independent analyses estimate that these automated permitting rules could trim rooftop solar costs by thousands. In other words, even small, costless policy changes like this can save you almost as much money as the huge solar tax credit did, and these great reforms are happening all the time, and they make the process much more convenient and reliable.

While Texas is making solar simpler, it’s also helping consumers have a good experience when going solar. As of this month, Texas law now also requires solar salespeople to register with the Texas Department of Licensing and Regulation. The same bill standardizes contracts and provides for mandatory disclosures of upfront cost and financing terms. The whole solar industry benefits when customers have a good solar experience. Word of mouth is vital to keeping solar shining.

There's yet another pro-solar Texas law that's also going into effect this month: in addition to SB 1202 (streamlining solar permits) and SB 1036 (regulating solar sales tactics), the legislature is also supporting the dissemination of information about your options when going solar via SB 1697. You can read more about these three brand-new pro-solar state laws here.

The end of the solar tax credit is not the end of the solar industry. Far from it.

New forecast shows impact of 'Big Beautiful Bill' on Texas clean energy generation

energy forecast

Texas is expected to see a 77-gigawatt decrease in power generation capacity within the next 10 years under the federal "One Big Beautiful Bill Act," which President Trump recently signed into law, a new forecast shows.

Primarily due to the act’s repeal of some clean energy tax credits, a forecast, published by energy policy research organization Energy Innovation Policy & Technology, predicts that Texas is expected to experience a:

54-gigawatt decline in capacity from solar power by 2035
23-gigawatt decline in capacity from wind power by 2035
3.1-gigawatt decline in capacity from battery-stored power by 2035
2.5-gigawatt increase in capacity from natural gas by 2035

The legislation “will reduce additions of new, cost-effective electricity capacity in Texas, raising power prices for consumers and decreasing the state’s GDP and job growth in the coming years,” the forecast says.

The forecast also reports that the loss of sources of low-cost renewable energy and the resulting hike in natural gas prices could bump up electric bills in Texas. The forecast envisions a 23 percent to 54 percent hike in electric rates for residential, commercial and industrial customers in Texas.

Household energy bills are expected to increase by $220 per year by 2030 and by $480 per year by 2035, according to the forecast.

Energy Innovation Policy & Technology expects job growth and economic growth to also take a hit under the "Big Beautiful Bill."

The nonprofit organization foresees annual losses of $5.9 billion in Texas economic output (as measured by GDP) by 2030 and $10 billion by 2035. In tandem with the impact on GDP, Texas is projected to lose 42,000 jobs by 2030 and 94,000 jobs by 2035 due to the law’s provisions, according to the organization.

The White House believes the "Big Beautiful Bill" will promote, not harm, U.S. energy production. The law encourages the growth of traditional sources of power such as oil, natural gas, coal and hydropower.

“The One Big Beautiful Bill Act is a historic piece of legislation that will restore energy independence and make life more affordable for American families by reversing disastrous Biden-era policies that constricted domestic energy production,” Interior Secretary Doug Burgum said in a news release.

Promoters of renewable energy offer an opposing viewpoint.

“The bill makes steep cuts to solar energy and places new restrictions on energy tax credits that will slow the deployment of residential and utility-scale solar while undermining the growth of U.S. manufacturing,” says the Solar Energy Industries Association.

Jason Grumet, CEO of the American Clean Power Association, complained that the legislation limits energy production, boosts prices for U.S. businesses and families, and jeopardizes the reliability of the country’s power grid.

“Our economic and national security requires that we support all forms of American energy,” Grumet said in a statement. “It is time for the brawlers to get out of the way and let the builders get back to work.”

Harris County officials seek more local control over data centers

data demands

Three Harris County officials are pushing for greater local control over the development and operation of data centers.

County Attorney Abby Kamin, County Commissioner Lesley Briones and County Commissioner Adrian Garcia recently called for action to give Harris County more power to regulate data centers.

As it stands now, Harris County “has little to no authority” over the construction of data centers, Briones said at a news conference. Harris County has 55 operating, under-construction, or planned data centers, according to a document filed with the county.

Briones outlined four steps being included in the Harris County commissioners’ exploration of potentially tighter local regulation of data centers:

Reviewing what Harris County can and cannot do regarding data centers
Creating a Harris County plan for the upcoming state legislative session aimed at granting more local control over data center construction and operations. State lawmakers would need to approve any changes in local control.
Establishing community “listening” sessions in Harris County about data centers
Notifying Harris County commissioners when a proposed data center seeks permits

Kamin noted Houston and Harris County lack zoning regulations, and the county’s 34 cities set their own zoning rules. Furthermore, she said, Texas Attorney General Ken Paxton has not issued a ruling on whether counties can impose a moratorium on development of data centers.

However, she said, “limited jurisdiction does not mean limited responsibility … New technology is arriving in our communities faster than our laws and institutions can keep up with, whether that’s data centers, AI or even drones.”

The effort by Kamin, Briones, and Garcia follows Gov. Greg Abbott’s recent statewide halt of new environmental and construction permits for data centers. State permitting is frozen until the Electric Reliability Council of Texas (ERCOT) and the Public Utility Commission of Texas complete their review of data centers.

Their initiative also comes amid growing public concern over the amount of electricity and water gobbled up by data centers, as well as residents’ own rising electric and water bills.

Houston-based CenterPoint Energy expects to connect 8 gigawatts of new data-center loads in the Houston area by 2029, with about 4 gigawatts to follow, Kamin said. That, she said, would significantly increase peak power demand.

“No industry should get to monopolize or run roughshod over residents, public safety, and our critical natural resources,” Kamin said.

That being said, Kamin and Briones stressed they take pride in Houston being the Energy Capital of the World and Texas being an economic powerhouse.

“This isn’t about being against technology or new technology, but growth has to go hand in hand with accountability,” Kamin said.

Garcia said he’s open to welcoming data centers as good corporate neighbors, but not without protecting the people who live near these projects.

“I’ll keep an open mind,” he said, “but I want to know what will ultimately be the benefit to the community. And right now, I need tools [to do that].”

Houston bio-based materials co. steps into new sustainable consumer products

a cleaner shoe

A more sustainable shoe can’t be built on a single material swap. From the hard plastics hidden inside a heel to the material covering a sneaker’s upper, footwear is a collection of components—and each presents a different challenge for companies trying to move away from conventional, petroleum-based materials.

Houston-based Rheom Materials wants to change that equation. The biomaterials company has launched a sustainable footwear platform featuring two of its bio-based alternatives: Benree, a biodegradable plastic designed for hard internal components, and ShoraiDura, a durable leather alternative for footwear uppers.

“A shoe is not one material; it is multiple parts working together as a system. Substituting a single material has never moved the needle,” Rheom founder and CEO Zimri Hinshaw said in a news release. “Rheom wants to make it easier for brands to make a positive impact. By providing an assortment of bio-based materials, brands can change the system, not just a swatch of it.”

Benree is Rheom’s alternative to conventional hard plastics used in footwear construction. The company says it is a 100 percent USDA-certified bio-based, biodegradable material with performance comparable to acrylonitrile butadiene styrene (ABS), a widely used engineering plastic.

The material has passed SATRA testing for high-heel applications with Bared Footwear, an Australian footwear brand.

“At Bared, we're constantly on a journey to remove plastic from our shoes. At the same time, our brand won't compromise on quality for the end customer,” Millie Richards, Bared’s head of sustainability, added in the release. “From samples and testing, Rheom has proven to be solving both of those problems for us. We look forward to seeing how they develop as a company and would love to use them in our shoes.”

Rheom says it is also exploring Benree for additional internal components, including toe puffs and heel counters.

The company’s ShoraiDura material addresses another major part of shoe construction: the upper, which must withstand repeated flexing, friction and wear while maintaining its appearance.

Containing about 80 percent bio-based content, ShoraiDura is engineered as a durable leather alternative for footwear. Rheom says the material’s molecular structure is designed to deliver the strength and durability required for demanding applications.

To demonstrate how the material could be used in finished products, Rheom worked with a Los Angeles-based footwear manufacturer to create two prototypes: an athletic sneaker and a textured skater shoe, both featuring ShoraiDura uppers.

The two offerings reflect the company’s broader strategy. Rather than asking brands to evaluate a single material in isolation, Rheom is positioning its platform as a way to explore alternatives across different parts of footwear construction.

The next step is broader industry adoption. Benree’s testing with Bared Footwear and ShoraiDura’s footwear prototypes offer early examples of how the materials could be applied, while commercial use will depend on manufacturers’ evaluations and product-development decisions.

Rheom Materials is a Houston-based biomaterials company developing bio-based alternatives to petrochemical plastics. Its product portfolio includes Shorai, a leather alternative, and Benree, a hard plastic alternative.

The company debuted Shorai at the Houston Livestock Show and Rodeo in 2025 and showed a bio-based "leather" collection in Milan earlier this year. Read more here.

Houston solar manufacturer expands facility, production capacity

houston expansion

Solar tracking and manufacturing company PV Hardware USA is increasing its production capacity and expanding its Houston facility in an effort to meet growing demands.

The move marks the company's third expansion in the Houston area in three years. PV Hardware reports a 400 percent surge in national market growth over the past three years, as solar-based projects have been pivotal in energy resilience efforts.

PV Hardware plans to increase the capacity at its Houston facility by 42 percent, according to a news release. With the additional capacity, PV Hardware expects a 35 percent increase in production of pre-assembled parts. The company has not announced whether any additional employees will be hired or the costs of expansion.

In September, the company completed its new dedicated pre-assembly facility, which will help migrate difficult assembly into an easier manufacturing setting. The new pre-assembly area will also assist with streamlined field installation, enhanced schedule predictability and reduction of manual labor.

Citybiz reports that the expansion totals approximately 34,200 square feet.

PV Hardware USA aims to make solar installation more efficient. For large-scale solar projects, PV Hardware USA’s pre-assembly process helps to relieve assembly work done by installation teams. According to PV Hardware USA, it reduces the number of on-site components by 70 percent.

“Traditionally, manufacturers pushed the assembly burden onto the jobsite,” Rodolfo Bitar, vice president of business development for PVH USA, told Renewable Energy Magazine. “We ask a different question: what work can be done more efficiently before the equipment ever leaves the factory? By managing the assembly of 188 loose parts per row in our controlled manufacturing environment, we remove field complexity and make installation highly predictable.”

PV Hardware USA produces single-axis solar trackers made in Texas and has supplied over 52 gigawatts of solar trackers worldwide.

“The expanded presence in Texas underscores a long-term commitment: bringing world-class solar expertise to local American manufacturing, supporting communities, and serving as a reliable partner through the clean energy transition,” the company said in the release.

In July of 2025, the company opened its 95,000-square-foot facility, which was the second Houston location following its initial $30 million U.S. manufacturing facility, which, at 50,000 square feet, is one of America's largest solar tracker manufacturing facilities.
