One year ago, the city of Houston announced its Climate Action Plan and its goal to reach carbon neutrality by 2050. This year, the city has another Earth Day announcement that builds upon CAP.

Mayor Sylvester Turner and solar nonprofit group, Solar United Neighbors, announced a citywide solar co-op on Earth Day — exactly one year since CAP launched. For an update on the plan's execution in Houston, click here for a report from the Kinder Institute for Urban Research.

"As we celebrate Earth Day, I'm proud to welcome this community-driven initiative for local rooftop solar and thank Solar United Neighbors for being such a strong supporter of the Houston Climate Action Plan," says Mayor Turner in a news release. "I encourage Houstonians to take full advantage of this opportunity to learn more about the benefits of residential solar and how they can take part. Bulk buy programs like this will help our city meet our energy transition goals and grow local investment in renewable and resilient energy."

SUN is familiar with Houston, and, since 2018, the nonprofit has hosted six neighborhood solar co-ops in Spring Branch, Lake Olympia, East Houston, Central Houston, the Woodlands, and West Houston. According to SUN, Texas solar co-ops provide 569 kW of solar power, $1.64 million in local economic investment, and more than 18.4 million pounds of lifetime carbon offsets.

"The co-op will enable homeowners and business owners in and around the city of Houston to join the growing community of people taking control of their energy bills and improving grid resilience by harnessing solar power," says Hanna Mitchell, Texas program director for SUN, in the release. "Together, we're building a movement to transform our electricity system into one that is cleaner, fairer, and shares its benefits more broadly."

Data from Environment Texas shows that Houston's installed solar capacity has quadrupled from 2018 to 2020, and Houston is the nation's largest municipal user of renewable energy in the United States, according to the release. Additionally, Houston Permitting Center saw a 63 percent increase in solar installation permits from 2019 to 2020.

For more information on the co-op, visit SUN's Houston website. Or, sign up for one of the two information sessions on Thursday, May 6, at 6:30 pm, or Wednesday, May 19, at noon.

Solar energy co-op shines light on sustainability for Houston-area residents

A nationwide nonprofit organization that focuses on promoting and educating on the use of solar energy, has chosen a local solar installer business for its West Houston co-op.

Solar United Neighbors, also known as SUN, was established in 2007 to represent the interests and needs of solar owners and those interested in going solar. The nonprofit has already helped more than 4,600 solar owners with over 35,000 kW installed. SUN is currently active in the Houston area with two co-ops formed.

The West Houston co-op, which opened in January of 2020, is open to residents and small businesses from Brookshire to Memorial City and Richmond. The co-op will be open to new members until July 31st. However, members have already chosen a local business, Sunshine Renewable Solutions to install solar panels for the group.

"It is an honor to be selected because we know how thoroughly the co-op reviewed each bid," says Sid Chandrashekar, vice president of sales and operations for Sunshine Renewable Solutions. "SUN's mission is aligned with ours when it comes to education efforts for solar energy, they use a community approach that is really informative to anybody that is interested in solar, and that's how we see ourselves more as educators and consultants."

Hanna Mitchell, the Texas Program Director for Solar United Neighbors says a co-op is a great way to reduce costs for local citizens looking to go solar. The co-op is free to join and there is no commitment to purchase panels.

"Through our education programs and events we hope to demystify the process of going solar," says Mitchell. "There is never any pressure to go forward with the installation, our main goal is to provide access to information so our members can make informed energy choices."

The West Houston co-op committee members chose Sunshine Renewable Solutions from seven other installers that put in a bid. Solar co-op members selected the local installer for their competitive pricing, battery options, and workmanship warranty.

Co-op member Joseph Garfunkel served on the committee who volunteered to review bids and choose an installer. Initially, he joined to learn more about the process to get solar in his home.

"I joined the West Houston Solar Co-op to learn more about the process for installing solar at my house, and to also to get an idea of the cost," says Garfunkel. "The solar co-op has been very helpful in providing webinars and other information describing the entire process."

The experts at SUN were able to hold events to further educate the members of the West Houston co-op of the benefits of solar investment, even after the rise of the coronavirus pandemic moved gatherings to virtual events.

Garfunkel, along with fellow residents of the committee, was able to select the best candidate among those who presented a bid.

"I found that our discussion during that process was extremely helpful," says Garfunkel. "We were able to in better understand the features being offered by the different vendors, as well as the different costs and options that are available."

Sunshine Renewable Solutions, for their part, says they are thrilled to have been chosen from the other solar installers that were in the competition.

"We've worked hard to build our reputation and spread the love of clean energy and energy independence in the Houston area," says Chandrashekar. "We are ecstatic to help more people go solar by providing them with amazing customer experience at an incredibly low cost."

Those interested in joining the West Houston co-op will be presented with an individualized proposal based on the group rate, which leads to a significant number of dollars saved on the cost.

SUN will be recruiting more members for its East Houston co-op that will close at the end of August.

Texas institute grants $12M to bring leading cancer researchers to Houston

cha-ching

Rice University has recruited a prominent Swedish cancer researcher thanks to a $6 million grant from the Cancer Prevention and Research Institute of Texas.

It’s among $68 million in research grants recently awarded by the state agency, and six recruitment grants totaling $16 million to bring leading cancer researchers to Texas.

A news release from the Cancer Prevention and Research Institute of Texas (CPRIT) describes Pernilla Wittung-Stafshede of the Chalmers University of Technology in Gothenburg, Sweden, as “an accomplished and highly gifted biophysical scientist tackling complicated biological questions regarding the role of metals and metal dysregulation in various diseases. She pioneered a new research field around the role of metal ions in the folding and function of metalloproteins.”

Metalloproteins account for nearly half of all proteins in biology, according to the National Institutes of Health. They “catalyze some of the most difficult and yet important functions in [nature], such as photosynthesis and water oxidation,” the federal agency says.

Wittung-Stafshede, a professor of chemical biology and life sciences at Chalmers, is a former professor at Rice.

Aside from the money for Wittung-Stafshede, Houston recruitment grants also went to:

  • University of Texas M.D. Anderson Cancer Center: $2 million to recruit Rosalie Griffin of the Mayo Clinic
  • Baylor College of Medicine: $2 million to recruit Dr. Nipun Verma of the Yale University School of Medicine
  • Baylor College of Medicine: $2 million to recruit Xin “Daniel” Gao of Harvard University and the Massachusetts Institute of Technology

In Houston, cancer research grants were given to:

  • Baylor College of Medicine: $7.8 million
  • M.D. Anderson Cancer Center: $20.7 million
  • Rice University: $ 1 million
  • University of Houston: $1.2 million
  • University of Texas Health Science Center at Houston: $4.5 million

“The awards … represent the depth and diversity of CPRIT funding for cancer research in Texas,” says Kristen Doyle, CEO of CPRIT. “These grants develop new approaches to preventing, diagnosing, treating, and surviving cancer for all Texans.”

2 Houston startups win big at SXSW 2025 pitch competition

winner, winner

Houston had a strong showing at this week's SXSW Pitch showcase in Austin, with two local startups claiming top prizes in their respective categories.

Little Place Labs, a Houston space data startup, won the Security, GovTech & Space competition. Clean-tech company Helix Earth, which spun out of Rice University and was incubated at Greentown Labs, won in the Smart Cities, Transportation & Sustainability contest.

As one of SWSX's marquee events, held March 8-10, the pitch competition featured 45 finalists, selected from 589 applicants, in nine categories.

"We faced impressive competition from a well-chosen set of finalists, and we're honored to be chosen as the winners. One of the judges even commented, ‘Who knew you could make air conditioning sexy,’” Brad Husick, Helix's co-founder and chief business officer, said in a release.

Helix Earth was launched in 2022 and is known for its space capsule air filtration system that was co-developed for NASA. The commercial air conditioner add-on technology, now in a pilot phase, has been used to retrofit HVAC systems for commercial buildings and can save up to 50 percent of the net energy, cutting down on emissions and operating costs, according to the company. Its co-founder and CEO Rawand Rasheed was named to the Forbes 30 Under 30 Energy and Green Tech list for 2025.

“This win validates our mission to drive sustainable innovation in commercial air conditioning and beyond. We are excited about the future of Helix Earth and the impact we will have in reducing energy consumption and emissions," Rasheed said in a statement.

Little Place Labs echoed that sentiment with a post on LinkedIn celebrating the win.

"This all started with a simple mission: To deliver real-time space insights to help first responders, mission planners, and decision-makers act before problems arise,” the post read. "Today, that mission feels even stronger."

The company uses advanced AI and machine learning to deliver near-real-time space analytics for both ground and space-based applications. Its software aims to help first responders, mission planners and decision-makers detect anomalies and make informed decisions quickly. It was co-founded in 2020 at Oxford by Houstonian and CEO Bosco Lai and Gaurav Bajaj and participated in the 2023 AWS Space Accelerator.

Two other Houston companies were selected as finalists:

  • Trez, a Latino-focused fintech company that uses AI and voice-command payroll through WhatsApp to provide culturally relevant payroll and streamline financial operations for Latino business owners.
  • Tempesst Droneworx, a veteran-owned software company that's Harbinger software providing real-time contextual intelligence for early warning detection, reducing time to decision and speeding time to action.

Jesse Martinez, founder of invincible, and Anu Puvvada of KPMG were two judges representing Houston.

According to SXSW, 647 companies have participated in SXSW Pitch over the years, with over 93 percent receiving funding and acquisitions totaling nearly $23.2 billion. See the full list of 2025 winners here.
