The global energy sector is on an exhilarating trajectory, teeming with promising technologies and unprecedented opportunities for a sustainable future. Yet, we find ourselves grappling with the challenges of reliability and affordability. As both a researcher in the field of power electronics and a consumer with bills to pay, I find myself experiencing mixed feelings.

As a researcher, I am thrilled by the progress we have achieved, particularly in energy conversion. The exponential growth of renewable energy technologies in Texas and beyond, including wind turbines and solar PV systems, is cause for celebration. These innovations, coupled with supportive policies, have facilitated widespread deployment and the potential to significantly reduce greenhouse gas emissions, combat climate change, and create a brighter future for our children.

While renewable energy resources can play a crucial role in maintaining the supply-demand balance of the grid, as they did by performing very well during the recent 2023 Texas heat wave, their intermittent and unpredictable nature can also pose a significant challenge to the power system. Unlike traditional power plants that operate continuously, wind turbines and solar PV systems rely on weather conditions for optimal performance. Fluctuations in wind speed, cloud cover, and sunlight intensity can lead to imbalances between energy supply and demand. This imbalance will worsen as the anticipated influx of electric vehicles and their charging needs come into play.

The volatility of renewables contributes to price fluctuations in the electricity market, which not only affects consumers but also raises concerns about grid resilience during extreme weather events. My electricity bill increased by over 20 percent compared to last year, partly caused by inflation, but mainly due to higher operational costs in the Texas electricity market.

Texas witnessed firsthand the consequences of a not-so-resilient grid through the severe power outages experienced during the "Polar Vortex" in February 2021. These outages not only disrupted lives but also disproportionately impacted vulnerable populations. During that time, my wife was expecting our second child. Enduring two nights in our frigid home without electricity or a fireplace was an ordeal that we navigated relatively unscathed. But it made me think of those less fortunate. These circumstances underscore the importance of establishing a robust, dependable and affordable electrical power system.

Balancing renewable energy growth and grid resilience requires a multifaceted approach:

  1. Investment in Infrastructure and Storage: It is crucial to strengthen the grid and ensure a reliable power supply. Upgrading transmission and distribution systems, integrating advanced monitoring and control technologies, and enhancing grid interconnections are essential. The Texas Legislature established the Powering Texas Forward Act, also known as Senate Bill 2627, a taxpayer-funded loan program, to encourage investment. While excluding certain renewable energy facilities and electric energy storage, it recognizes the need for a reliable grid. Hydrogen fuel cell generation facilities could be a potential solution, providing clean and stable energy while remaining eligible for the loan program. Additionally, implementing large-scale energy storage systems utilizing batteries and hydrogen storage technologies can mitigate renewable energy volatility by storing excess energy until needed. The Texas energy industry's push for these advances is a significant step in the right direction.
  2. Diversification of Energy Sources: While renewables play a crucial role in decarbonization, a mix of renewable sources, natural gas, and other low-carbon resources is necessary for the foreseeable future. Implementing carbon capture, utilization, and storage (CCUS) technologies across industries can mitigate associated climate impacts. The failure of Senate Bill 624, which would have had significant repercussions for wind and solar facilities, indicates that Texas legislators are genuinely concerned about clean, alternative sources of energy. However, a lot more needs to be done, including coordinated actions between federal, state, and international governments, to address the urgent issue of climate change. Texas can leverage its hydrocarbon/energy expertise to produce economical green and blue hydrogen, advanced fuel cells and hydrogen-based internal combustion engine technologies, enabling a smoother energy transition in terms of usage and jobs.
  3. Educating the General Public: It is critical to help people understand the necessity of modernizing our energy infrastructure; the benefits and opportunities it brings and the transformations we can expect. Institutions like the University of Houston play a crucial role in advancing clean energy technologies and educating the future energy workforce. The establishment of the Texas University Fund (TUF), with a budget of over $3 billion, through a constitutional amendment in November 2023, will be a pivotal step toward this goal.

When addressing the energy transformation and grid resilience dilemma, the real-life impact on human beings must be of prime importance. Our leaders should focus on a balanced approach considering grid infrastructure investment, diversification of energy sources, energy storage solutions, and public education. By adopting this multifaceted strategy, we can ensure a reliable, resilient, and affordable energy future.

Texas improves ranking on annual report of most innovative states

moving up

Texas ranks above average — but outside the top 10 — in a new index that ranks the most innovative states.

To come up with its Most and Least Innovative States ranking, personal finance website WalletHub looked at 25 key indicators of innovation for the 50 states and the District of Columbia. These include a state’s share of STEM professionals, research and development spending per capita, and the proliferation of tech companies.

With an innovation score of 48.96 out of 100, Texas lands at No. 13 on the list. The District of Columbia stands atop the list, with an innovation score of 69.79, followed by Massachusetts, California, Colorado, and Washington.

Texas has steadily inched up the list — the state was No. 14 on the list in 2024 and has climbed up one spot each year since 2021.

Two components make up each state’s score: human capital and “innovation environment.” Texas ranks 14th in the human capital category and 13th in the innovation environment category.

“The most innovative states are especially attractive to people who have majored in science, technology, engineering and math, or STEM, as they offer abundant career opportunities and investment dollars, both for jobs at existing companies and for startups,” says WalletHub analyst Chip Lupo. “These states also instill young students with the skills they need to succeed in the current workforce, skills which are useful whether or not they pursue a STEM career.”

Despite not placing in the top 10 of the WalletHub index, Texas continues to produce thousands of jobs.

Citing data from the U.S. Bureau of Labor Statistics, Gov. Greg Abbott says Texas added the most nonfarm jobs in January (27,900) of any state and the most nonfarm jobs from January 2024 to January 2025 (187,700).

“Texas is America’s jobs engine, adding more new jobs in the last year than any other state,” Abbot said in a news release. “Our skilled and growing workforce and our business-friendly climate attract job-creating businesses in diverse industries from across the country and around the world. … Texas continues to remove regulatory red tape and invest in education, innovation, and infrastructure as we build a stronger, more prosperous Texas than ever before.”

Houston researchers find AI provides fresh perspectives to everyday problems

We all know ChatGPT has forever changed how we do business. It’s modified how we access information, compose content and analyze data. It’s revolutionized the future of work and education. And it has transformed the way we interact with technology.

Now, thanks to a recent paper by Jaeyeon (Jae) Chung (Rice Business), we also know it’s making us better problem solvers.

Key findings:

  • A recent study finds ChatGPT-generated ideas are deemed an average of 15% more creative than traditional methods.
  • ChatGPT enhances “incremental,” but not “radical,” innovation.
  • ChatGPT boosts creativity in tasks normally associated with human traits, like empathy-based challenges.

According to the study published in Nature Human Behavior by Chung and Byung Cheol Lee (University of Houston), ChatGPT enhances our problem-solving abilities, especially with everyday challenges. Whether coming up with gifts for your teenage niece or pondering what to do with an old tennis racquet, ChatGPT has a unique ability to generate creative ideas.

“Creative problem-solving often requires connecting different concepts in a cohesive way,” Chung says. “ChatGPT excels at this because it pulls from a vast range of data, enabling it to generate new combinations of ideas.”

Can ChatGPT Really Make Us More Creative?

Chung and Lee sought to answer a central question: Can ChatGPT help people think more creatively than traditional search engines? To answer this, they conducted five experiments.

Each experiment asked participants to generate ideas for solving challenges, such as how to repurpose household items. Depending on the experiment, participants were divided into one of two or three groups: one that used ChatGPT; one that used conventional web search tools (e.g., Google); and one that used no external tool at all. The resulting ideas were evaluated by both laypeople and business experts based on two critical aspects of creativity: originality and appropriateness (i.e., practicality).

In one standout experiment, participants were asked to come up with an idea for a dining table that doesn’t exist on the market. The ChatGPT group came up with suggestions like a “rotating table,” a “floating table” and even “a table that adjusts its height based on the dining experience.” According to both judges and experts, the ChatGPT group consistently delivered the most creative solutions.

On average, across all experiments, ideas generated with ChatGPT were rated 15% more creative than those produced by traditional methods. This was true even when tasks were specifically designed to require empathy or involved multiple constraints — tasks we typically assume humans might be better at performing.

However, Chung and Lee also found a caveat: While ChatGPT excels at generating ideas that are “incrementally” new — i.e., building on existing concepts — it struggles to produce “radically” new ideas that break from established patterns. “ChatGPT is an incredible tool for tweaking and improving existing ideas, but when it comes to disruptive innovation, humans still hold the upper hand,” Chung notes.

Charting the Next Steps in AI and Creativity

Chung and Lee’s paper opens the door to many exciting avenues for future study. For example, researchers could explore whether ChatGPT’s creative abilities extend to more complex, high-stakes problem-solving environments. Could AI be harnessed to develop groundbreaking solutions in fields like medicine, engineering or social policy? Understanding the nuances of the collaboration between humans and AI could shape the future of education, work and even (as many people fear) art.

For professionals in creative fields like product design or marketing, the study holds especially significant implications. The ability to rapidly generate fresh ideas can be a game-changer in industries where staying ahead of trends is vital. For now, take a second before you throw out that old tennis racquet. Ask ChatGPT for inspiration — you’ll be surprised at how many ideas it comes up with, and how quickly.

Rice, MD Anderson receive $1.5 million to further brain cancer research

fresh funding

Rice University chemist Han Xiao, who also serves as director of the university’s Synthesis X Center, and cancer biologist Dihua Yu of The University of Texas MD Anderson Cancer Center have received a three-year, $1.5 million grant from the Robert J. Kleberg Jr. and Helen C. Kleberg Foundation.

The funding will allow them to continue their research on treating brain metastasis by overcoming the blood-brain barrier, or the BBB, according to a news release.

Brain metastasis is the leading form of brain cancer, with survival rates below 20 percent within a year of diagnosis, according to the National Library of Medicine. It commonly originates from breast, lung and melanoma cancers.

The BBB typically acts as a protective barrier for the brain. However, it prevents most drugs from being able to directly reach the brain. According to Rice, only 2 percent of FDA-approved small molecule drugs can penetrate the BBB, limiting treatment options.

Xiao and Yu’s approach to dealing with the BBB includes a light-induced brain delivery (LIBD) platform. The advanced system employs nanoparticles that are embedded with a near-infrared dye for the transport of therapeutic agents across the BBB. The research will evaluate the LIBD’s ability to improve the delivery of small-molecule drugs and biological therapies. Some therapies have shown potential for reducing cancer growth in laboratory studies, but they have struggled due to limited BBB penetration in animal models.

“Our LIBD platform represents a novel strategy for delivering drugs to the brain with precision and efficiency,” Xiao said in a news release. “This technology could not only improve outcomes for brain metastasis patients but also pave the way for treating other neurological diseases.”

The Kleberg Foundation looks for groundbreaking medical research proposals from leading institutions that focus on “innovative basic and applied biological research that advances scientific knowledge and human health” according to the foundation.

“This research is a testament to the power of collaboration and innovation,” Xiao said in a news release. “Together, we’re pushing the boundaries of what’s possible in treating brain metastasis and beyond.”

Rice launched the Synthesis X Center, or Synth X, last spring. It was born out of what started about eight years ago as informal meetings between Xiao's research group and others from the Baylor College of Medicine’s Dan L Duncan Comprehensive Cancer Center. It aims to turn fundamental research into clinical applications through collaboration.

“This collaboration builds on the strengths of both research teams,” Xiao said in the release. “By combining SynthX Center's expertise in chemistry with Dr. Yu's expertise in cancer biology and brain metastases, we aim to create a transformative solution.”
