As the cost of solar panel installation becomes more attainable to homeowners, more Americans are willing to reduce their carbon emissions and their electricity bills in the process.

So just where does Houston rank in new tech like solar panel installation? According to a new report from home service management platform Thumbtack, it doesn't.

Houston, which has no shortage of sun — as residents are well aware — fails to place in Thumbtack's new list of the top 15 most "solar" cities in the United States.

Austin leads the way for Texas, ranking the No. 3 most “solar” city in the U.S., per Thumbtack. Austin, with the highest net-new solar panel installations within the past year in Texas, splits up four Californian cities in the top five. Only San Diego (No. 1) and Los Angeles (No. 2) outranked Austin.

San Antonio follows not behind atNo. 9 and just outside the top 10 is Dallas-Fort Worth at No. 11.

For the curious, Texas Property Code 202.010 forbids homeowner associations from restricting the installation of solar panels, so any Texas homeowner can do it as long as they follow the standard procedure for “improving” their home to comply with a separate state law.

Thumbtack home expert David Steckel said in a press release that they chose to focus the report on cities with the most new solar installations because they wanted to “celebrate those [cities] making the biggest change.”

“When we looked at all solar projects – from installations to modifications, repairs, consultations and more – we found that unsurprisingly, California dominated the list with 9 out of the top 10 spots – given their long-term commitment to and adoption of solar energy," he said. "We really wanted to celebrate cities that are seeing a shift in behavior.”

The top 10 most “solar” cities in the U.S. are:

  • No. 1 – San Diego
  • No. 2 – Los Angeles
  • No. 3 – Austin
  • No. 4 – Palm Springs, California
  • No. 5 – San Francisco
  • No. 6 – Las Vegas
  • No. 7 – Phoenix
  • No. 8 – Orlando
  • No. 9 – San Antonio
  • No. 10 – Tampa, Florida

Steckel said the company has seen a year-over-year increase of up to 96 percent in solar energy projects among consumers for March 2023.

“We recently found that 71 percent of Americans are prioritizing sustainable, energy-efficient home improvement projects this year – with more than one-third of Americans planning to install solar panels in 2023 – showing an accelerating change in consumer behavior,” he said.

Rice University harnesses nanotech to revolutionize clean water access

getting clean

Researchers at Rice University are making cleaner water through the use of nanotech.

Decades of research have culminated in the creation of the Water Technologies Entrepreneurship and Research (WaTER) Institute launched in January 2024 and its new Rice PFAS Alternatives and Remediation Center (R-PARC).

“Access to safe drinking water is a major limiting factor to human capacity, and providing access to clean water has the potential to save more lives than doctors,” Rice’s George R. Brown Professor of Civil and Environmental Engineering Pedro Alvarez says in a news release.

The WaTER Institute has made advancements in clean water technology research and applications established during a 10-year period of Nanotechnology Enabled Water Treatment (NEWT), which was funded by the National Science Foundation. R-PARC will use the institutional investments, which include an array of PFAS-dedicated advanced analytical equipment.

Alvarez currently serves as director of NEWT and the WaTER Institute. He’s joined by researchers that include Michael Wong, Rice’s Tina and Sunit Patel Professor in Molecular Nanotechnology, chair and professor of chemical and biomolecular engineering and leader of the WaTER Institute’s public health research thrust, and James Tour, Rice’s T.T. and W.F. Chao Professor of Chemistry and professor of materials science and nanoengineering.

“We are the leaders in water technologies using nano,” adds Wong. “Things that we’ve discovered within the NEWT Center, we’ve already started to realize will be great for real-world applications.”

The NEWT center plans to equip over 200 students to address water safety issues, and assist/launch startups.

“Across the world, we’re seeing more serious contamination by emerging chemical and biological pollutants, and climate change is exacerbating freshwater scarcity with more frequent droughts and uncertainty about water resources,” Alvarez said in a news release. “The Rice WaTER Institute is growing research and alliances in the water domain that were built by our NEWT Center.”

3 Houston innovators to know this week

who's who

Editor's note: Every week, I introduce you to a handful of Houston innovators to know recently making headlines with news of innovative technology, investment activity, and more. This week's batch includes three innovators across robotics, climatetech, and more.

Dianna Liu, founder and CEO of ARIX Technologies

After working for years in the downstream energy industry where safety and efficiency were top priorities, Dianna Liu thought there was a way technology could make a huge difference.

Despite loving her company and her job, she took a leap of faith to start a robotics company to create technology to more safely and efficiently monitor corrosion in pipelines. ARIX Technologies has developed software and hardware solutions for its customers with pipelines in downstream and beyond.

"Overall, this industry is an industry that really harps on doing things safely, doing things well, and having all the data to make really informed decisions," Liu says on the Houston Innovators Podcast. "Because these are huge companies with huge problems, it takes a lot of time to set up the right systems, adopt new things, and make changes." Continue reading.

Rawand Rasheed, co-founder and CEO of Helix Earth

Helix Earth Technologies closed an oversubscribed $5.6 million seed funding led by Houston-based research and investment firm Veriten. Anthropocene Ventures, Semilla Capital, and others including individual investors also participated in the round.

“This investment will empower the Helix Earth team to accelerate the development and deployment of our first groundbreaking hardware technology designed to disrupt a significant portion of the commercial air conditioning market, an industry that is ready for innovation,” Rawand Rasheed, Helix Earth co-founder and CEO, says in a news release.

In a guest column, Nada Ahmed, founding partner at Houston-based Energy Tech Nexus, draws a uniquely Houston comparison between the health tech innovation sector and that of the climate tech world.

"Over the past several decades, climate tech has faced numerous challenges, ranging from inconsistent public support to a lack of funding from cautious investors. While grassroots organizations and climate innovators have made notable efforts to address urgent environmental issues, we have yet to see large-scale, lasting impact," she writes.

"A common tendency is to compare climate tech to the rapid advancements made in digital and software technology, but perhaps a more appropriate parallel is the health tech sector, which encountered many of the same struggles in its early days," she continues. Continue reading.
