solar-powered spotlight

Green Mountain Energy Sun Club has supplied a grant of nearly $103,000 to a local Indian arts center to make sustainable improvements to its facilities.

Silambam Houston will use the grant to help with the installation of a rooftop solar array and a new pavilion at its Pearland dance studio, which will be called The Green Mountain Energy Sun Club Sustainability Pavilion. The venue will serve as an outdoor gathering space for events at the facility.

“At Green Mountain Energy, we recognize that our choices can have a profound impact on our environment,” Mark Parsons, Green Mountain Energy vice president, says in a news release. “We’re proud to support the rich and diverse culture of the Indian community, and we’re glad to help Silambam take the next step toward a more sustainable future.”

The 14.58 kW solar structure is expected to offset 100 percent of the building’s energy needs, which would save the organization more than $4,000 per year for the next 25 years. Sun Club has donated more than $14 million for 164 projects across Texas and the Northeast since it was founded in 2022.

Silambam is an Indian classical arts organization with an arts academy program that serves 180 students each week with more than 20 teaching artists on staff. The professional dance company has more than 20 dancers that regularly perform at Houston venues like Miller Outdoor Theater where they will perform next on June 7.

“We are thrilled to be able to weave sustainable practices into our arts programming, while also giving back to the community,” founder and executive artistic director of Silambam Dr. Lavanya Rajagopalan said in a news release. “The annual savings from this project will allow us to increase artist pay, provide tuition waivers for economically disadvantaged students, and/or provide free or pay-what-you-can access to our ArtStream Concerts, all while benefiting the environment.”

Houston organization celebrates zero waste goal

earth day win

Discovery Green celebrated Earth Day with a major milestone this year — achieving it’s Zero Waste goal.

The nonprofit, along with Citizens’ Environmental Coalition and Houston Public Works, are announced that the 2024 Green Mountain Energy Earth Day, which generated more than 3,800 pounds of garbage, diverted the majority of that waste from landfills. "Zero Waste," as defined by the Environmental Protection Agency, is successfully diverting at least 90 percent of waste from the landfill.

On Earth Day, Discovery Green composted 2,200 pounds of waste and recycled 1,300 pounds of trash.

“Part of Discovery Green Conservancy’s mission is to serve as a village green for our city and be a source of health and happiness for all. Our goal is to sustain an exceptional environment for nature and people,” Discover Green President Kathryn Lott says in a news release. “We are beyond thrilled to have achieved Zero Waste certification.”

The achievement was made possible by volunteers from the University of Houston – Downtown.

Steve Stelzer, president of Citizens’ Environmental Coalition’s board of directors, acknowledged how rare the achievement is in a public space in a major city like Houston.

“Discovery Green Conservancy stepped up and made a commitment to weigh, measure and record everything. They should be congratulated to have done this at this scale,” Stelzer adds. “The Conservancy said they were going to do it and they did. It’s an amazing accomplishment.”

The 2024 event included:

  • 31,000 visitors in attendance
  • 60 + exhibitors
  • 100 + volunteers
  • 12 artists
    • 9 chalk artists
    • Donkeeboy and Donkeemom
    • Mark Bradford
  • 25 Mark Bradford artworks made of scrap presented in partnership with Houston First
  • 4 short films shown
  • 3,836.7 pounds of waste collected during Green Mountain Energy Earth Day

Houston nonprofit flips switch on solar panel project thanks to sustainability grant

shine on

A Houston-area farm is one step closer to operating completely off-grid thanks to new solar panels installed with funding provided by a grant.

In a step towards a greener future, Hope Farms, a 7-acre farm operated by a Houston nonprofit organization, Recipe for Success Foundation, unveiled 18 new solar panels on Tuesday. This significant move is part of a collective effort to completely transition the farm to solar power, demonstrating its commitment to sustainability.

“The industry (solar power) itself is intimidating to people,” Gracie Cavner, founder and CEO of Hope Farms and Recipe for Success, tells EnergyCapital. “Part of our work is to inspire people to replicate what we're doing. We want to show that things aren't as hard as you think they are.”

The nonprofit organization is recognized in Houston for its work in addressing childhood obesity, with a long held mission of demystifying the common misconceptions around healthy eating. It is now tackling another challenge: dispelling the myth that solar power implementation is difficult. Hope Farms' latest initiative will not only further its energy independence, it will also show that adopting renewable energy, similar to embracing healthy food choices, is a feasible option.

The 18 solar panels will power the farm's composting toilet facility and all of the electricity used in its barn, which acts as its market stand and kitchen. Its next green phase is fast approaching and will implement solar panels on top of its flower studio, where the farm's internet and security systems reside. Its final phase will install a water well pump.

“We really did a lot of direct learning,” Cavner said. “We worked directly with solar engineers, not somebody with a company that benefited from us making one decision or another. I feel like more people would have solar if they realized they could do that.”

This is not the first green step Hope Farms has taken thanks to a Green Mountain Energy Sun Club grant, and certainly not the last. Last year, the farm cut the ribbons to its rainwater capture system that now saves roughly 95,000 gallons of water per year by capitalizing on the city’s abundant rainfall.

Since the farms beginning in 2016, it has relied on solar, even when it was only fields lit by a few lights. Soon, Hope Farms will be completely off-grid, running its entire operation on sustainable resources.

“With this expansion, I feel like it’s going to be taking the rock out of the middle of the river,” Cavner said. “It’s going to open up this train and make it easier for anybody to jump in and do it. The first step is kicking the door open and making more people want to pursue it.”

Houston researchers propose model to scale e-waste recycling

critical research

The “missing link” in critical minerals may have been in our junk drawers all along, according to new research from the University of Houston.

Jian Shi, an associate professor in the UH Cullen College of Engineering, and his team have unveiled a new supply chain model that aims to make e-waste economically viable and could help make large-scale recycling possible.

Shi, along with professor Kailai Wang and graduate researcher Chuyue Wang, published the work in a recent issue of Nature. Their study outlines how gold, lithium and cobalt from discarded electronics can be kept circulating in the U.S. through the process of “urban mining.” It was supported by the U.S. Department of Energy’s Office of Energy Efficiency and Renewable Energy (EERE) through the Vehicle Technologies Office.

The team’s research found that e-waste is the fastest-growing solid waste stream in the world. When waste from smartphones or tablets is left unmanaged, the devices can leak hazardous waste and pose significant fire risks due to aging batteries. Additionally, when they are shipped off to foreign landfills, the U.S. loses the potential to recycle or reuse the critical minerals left inside.

“A lot of people have iPads or old iPhones sitting in their drawers right now, and that’s a waste of a critical resource,” Shi said in a news release. “Urban mining allows us to extract the same high-value materials found in traditional mines without the environmental destruction. More importantly, it helps secure our domestic supply chain for the technologies of tomorrow.”

According to UH, recycling e-waste has not succeeded in the U.S. due to a fragmented recycling system, in which manufacturers, collectors and recyclers operate separately, driving up costs.

The UH team's research looks to change that.

In the study, the researchers modeled streamlined recycling efforts by mapping the interactions between manufacturers and independent recycling markets. Their dual-channel closed-loop supply chain (CLSC) model identified how these players can transition from competitors to partners, which can distribute profits more equitably and make recycling efforts more financially attractive.

According to UH, the research has particular significance due to the growing demand for electronic vehicles and their batteries.

“We can improve the performance of the entire recycling ecosystem and make the profit distribution more balanced,” Wang said in the release. “This ensures that the materials we need for EVs and advanced electronics stay right here in the U.S.”

“By making recycling work at scale, we aren’t just cleaning up waste,” Shi added. “We’re building a foundation that benefits both our national security and our economy.”

1PointFive signs latest deal, shares update on $1.3B carbon removal project

DAC deal

Houston-based 1PointFive, a subsidiary of Occidental Petroleum Corp., has secured another buyer of carbon dioxide removal credits for its $1.3 billion STRATOS project as it moves toward operation.

Bain & Company, a Boston-based consulting firm, has agreed to purchase 9,000 metric tons of carbon dioxide removal (CDR) credits from the direct air capture (DAC) facility over three years, according to a news release. DAC technology pulls CO2 from the air at any location, not just where carbon dioxide is emitted.

The deal is Bain's first purchase of DAC removal credits. The company has developed a program that helps clients purchase carbon credits from a range of carbon-removal technologies.

"We are proud to partner with 1PointFive and add them to our portfolio of engineered carbon removal technologies," Sam Israelit, Bain’s chief sustainability officer, said in the news release. "Their track record for developing DAC technology, coupled with their deep understanding of what it takes to deliver large-scale infrastructure projects, uniquely positions them to be a leader in this emerging segment.”

“We believe this agreement demonstrates continued momentum for the solution while supporting the development of vital domestic infrastructure,” Anthony Cottone, president and general manager of 1PointFive, added in the release.

Bain joins others like Microsoft, Amazon, AT&T, Airbus, the Houston Astros and the Houston Texans that have agreed to buy CDR credits from STRATOS.

The Texas-based STRATOS project is being developed through a joint venture with investment manager BlackRock and is designed to capture up to 500,000 metric tons of CO2 per year. The U.S Environmental Protection Agency approved Class VI permits for the project last year.

1PointFive says STRATOS is "progressing through start-up activities." The company shared in a LinkedIn post that Phase 1 of the project is expected to go online in Q2, with Phase 2 ramping up through the remainder of 2026.

Houston researcher develops efficient method to cool AI data centers

cool findings

A University of Houston professor has developed a new cooling method that can remove heat at least three times more effectively from AI data centers than current technologies.

Hadi Ghasemi, a distinguished professor of Mechanical & Aerospace Engineering at UH, published his findings in two articles in the International Journal of Heat and Mass Transfer. The findings solve a critical issue in the growing AI sector, according to UH.

High-powered AI data centers generate huge amounts of heat due to the GPU and operating systems they use with extreme power densities, which introduce complex thermal challenges. Traditionally, cooling methods, like microchannels, which use flow and spray cooling, have had limitations when exposed to extreme heat flux, according to UH.

Ghasemi’s research, however, found a more effective way to design thin-film evaporation structures to release heat from data centers and electronics at record performance.

Ghasem’s solution coupled topology optimization and AI modeling to determine the best shapes for thin film efficiency, ultimately landing on a branch-like structure—resembling a tree.

The model found that the “branches” needed to be about 50 percent solid and 50 percent empty space for optimum efficiency, and that they could sustain high heat fluxes with minimal thermal resistance.

“These structures could achieve high critical heat flux at much lower superheat compared to traditionally studied structures,” Ghasemi said in a news release. “The new structures can remove heat without having to get as hot as previous removal systems.

Ghasemi’s doctoral candidates, Amirmohammad Jahanbakhsh and Saber Badkoobeh Hezave, also worked on the project. The team believes their results show the impact of a physics-aware, AI design and can help ensure reliability, longevity and stability of AI data centers.

“Beyond achieving record performance, these new findings provide fundamental insight into the governing heat-transfer physics and establishes a rational pathway toward even higher thermal dissipation capacities,” Ghasemi added in the release
