The City of Houston continues to electrify the country when it comes to the use of green power.

The U.S. Environmental Protection Agency (EPA) ranks the city first among municipal entities for the highest annual consumption of power from renewable sources. The list features participants in the EPA's Green Energy Partnership.

The EPA pegs the City of Houston's annual use of green power at a little over 1 billion kilowatt-hours. That's enough electricity to power more than 94,000 average U.S. homes in a year's time. No other municipal entity uses more than 1 billion kilowatt-hours of green power per year.

The City of Houston has held the No. 1 spot on the municipal list since 2014. Among all users of green power in the U.S. that participate in the EPA's Green Energy Partnership, the city ranks 19th.

Since July 2020, all City of Houston facilities have been powered by 100 percent renewable energy derived from solar and wind sources. Houston-based NRG supplies the electricity for those facilities.

In an August 11 news release, Houston Mayor Sylvester Turner says the EPA recognition is "great news for the city of Houston and, by extension, for the rest of the world. We are going big to set the example for cities around the world. If 100 percent renewable energy can happen in Houston, it can happen in any other city."

The news release points out that green power helps offset damage from ozone, acid rain, haze, fine particles, and other harmful pollutants. Fine particles come primarily from exhaust produced by vehicles, as well as from the burning of coal, wood, and heating oil, and from forest fires and grass fires.

The City of Houston isn't the only municipal outfit in Texas that shines on the EPA list. Here's are four others among the top 30 municipal users of green power:

  • City of Dallas, ranked second, 701.8 million kilowatt-hours of green power used each year.
  • Dallas-Fort Worth International Airport, ranked fifth, 450.2 million kilowatt-hours of green power used each year.
  • City of Austin, ranked sixth, 325.3 million kilowatt-hours of green power used each year.
  • City of Irving, ranked 30th, 24.9 million kilowatt-hours of green power used each year.

Nationally, these five Texas businesses rank among the top corporate users of green power:

  • Dallas-based AT&T, ranked seventh, 2.36 billion kilowatt-hours of green power used each year.
  • Irving-based Kimberly-Clark, ranked 18th, 1.03 billion kilowatt-hours of green power used each year.
  • Round Rock-based Dell, ranked 46th, 365.6 million kilowatt-hours of green power used each year.
  • Houston-based Solvay America, ranked 61st, 220 million kilowatt-hours of green power used each year.
  • Plano-based Cinemark USA, ranked 95th, 120.2 million kilowatt-hours of green power used each year.

Two Texas schools appear on the list of the top colleges and universities for use of green power:

  • University of North Texas in Denton, ranked 17th, 80.3 million kilowatt-hours of green power used each year.
  • Fort Worth-based Tarrant County College District, ranked 25th, 57.1 million kilowatt-hours of green power used each year.

Four Texas institutions show up on the list of the top K-12 users of green power:

  • Austin ISD, ranked second, 19.8 million kilowatt-hours of green power used each year.
  • Lake Travis ISD (select schools), ranked 12th, 960,000 kilowatt-hours of green power used each year.
  • The da Vinci School in Dallas, ranked 15th, 237,990 kilowatt-hours of green power used each year.
  • The Empower School in Austin, ranked 17th, 115,314 kilowatt-hours of green power used each year.

The EPA's ranking of the largest users of green power across the country "is proof that good business practices can also benefit the environment," says James Critchfield, director of the EPA's Green Power Partnership.

Building Houston

While it might seem like the COVID-19 pandemic has settled down for the time being, there's plenty of innovative research ongoing to create solutions for affordable vaccines and tech-enabled protection against the spread of the virus.

Some of that research is happening right here in Houston. Here are two innovative projects in the works at local institutions.

UH researcher designs app to monitor best times to shop

When is the best time to run an errand in the pandemic era we currently reside? There might be an app for that. Albert Cheng, professor of computer science and electrical and computer engineering at the University of Houston, is working on a real-time COVID-19 infection risk assessment and mitigation system. He presented his plans at the Institute of Electrical and Electronics Engineers conference HPC for Urgent Decision Making and will publish the work in IEEE Xplore.

Cheng's work analyzes up-to-date data from multiple open sources to see when is the best time to avoid crowds and accomplish activities outside the home.

"Preliminary work has been performed to determine the usability of a number of COVID-19 data websites and other websites such as grocery stores and restaurants' popular times and traffic," Cheng says in a UH release. "Other data, such as vaccination rates and cultural factors (for example, the percentage of people willing to wear facial coverings or masks in an area), are also used to determine the best grocery store to shop in within a time frame."

To use the app, a user would input their intended destinations and the farthest distance willing to go, as well as the time frame of the trip. The risk assessment and mitigation system, or RT-CIRAM, then "provides as output the target location and the time interval to reach there that would reduce the chance of infections," said Cheng.

There's a lot to it, says Cheng, and the process is highly reliant on technology.

"We are leveraging urgent high-performance cloud computing, coupled with time-critical scheduling and routing techniques, along with our expertise in real-time embedded systems and cyber-physical systems, machine learning, medical devices, real-time knowledge/rule-based decision systems, formal verification, functional reactive systems, virtualization and intrusion detection," says Cheng.

2 Houston hospitals team up with immunotherapy company for new vaccine for Africa

Baylor College of Medicine and Texas Children's Hospital have teamed up with ImmunityBio Inc. — a clinical-stage immunotherapy company — under a licensing agreement to develop a safe, effective and affordable COVID-19 vaccine.

BCM has licensed out a recombinant protein COVID-19 vaccine candidate that was developed at the Texas Children's Hospital Center for Vaccine Development to ImmunityBio. According to the release, the company engaged in license negotiations with the BCM Ventures team, about the vaccine that could address the current pandemic needs in South Africa.

"We hope that our COVID-19 vaccine for global health might become an important step towards advancing vaccine development capacity in South Africa, and ultimately for all of Sub-Saharan Africa," says Dr. Peter Hotez, professor and dean of the National School of Tropical Medicine at Baylor and co-director of the Texas Children's Hospital Center for Vaccine Development.

ImmunityBio, which was founded in 2014 by Dr. Patrick Soon-Shiong, is working on innovative immunotherapies that address serious unmet needs in infectious diseases, according to a news release from BCM.

"There is a great need for second-generation vaccines, which are accessible, durable and offer broad protection against the emerging variants," says Soon-Shiong. "ImmunityBio has executed on a heterologous ("mix-and-match") strategy to develop a universal COVID-19 vaccine. To accomplish this, we have embarked upon large-scale good manufacturing practices and development of DNA (adenovirus), RNA (self-amplifying mRNA) and subunit protein (yeast) vaccine platforms. This comprehensive approach will leverage our expertise in these platforms for both infectious disease and cancer therapies."
