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 scientists develop 'recharge-to-recycle' reactor for lithium-ion batteries

reduce, recharge, recycle

Engineers at Rice University have developed a cleaner, innovative process to turn end-of-life lithium-ion battery waste into new lithium feedstock.

The findings, recently published in the journal Joule, demonstrate how the team’s new “recharge-to-recycle” reactor recharges the battery’s waste cathode materials to coax out lithium ions into water. The team was then able to form high-purity lithium hydroxide, which was clean enough to feed directly back into battery manufacturing.

The study has major implications for the electric vehicle sector, which significantly contributes to the waste stream from end-of-life battery packs. Additionally, lithium tends to be expensive to mine and refine, and current recycling methods are energy- and chemical-intensive.

“Directly producing high-purity lithium hydroxide shortens the path back into new batteries,” Haotian Wang, associate professor of chemical and biomolecular engineering, co-corresponding author of the study and co-founder of Solidec, said in a news release. “That means fewer processing steps, lower waste and a more resilient supply chain.”

Sibani Lisa Biswal, chair of Rice’s Department of Chemical and Biomolecular Engineering and the William M. McCardell Professor in Chemical Engineering, also served as co-corresponding author on the study.

“We asked a basic question: If charging a battery pulls lithium out of a cathode, why not use that same reaction to recycle?” Biswal added in the release. “By pairing that chemistry with a compact electrochemical reactor, we can separate lithium cleanly and produce the exact salt manufacturers want.”

The new process also showed scalability, according to Rice. The engineers scaled the device to 20 square centimeters, then ran a 1,000-hour stability test and processed 57 grams of industrial black mass supplied by industry partner Houston-based TotalEnergies. The results produced lithium hydroxide that was more than 99 percent pure. It also maintained an average lithium recovery rate of nearly 90 percent over the 1,000-hour test, showing its durability. The process also worked across multiple battery chemistries, including lithium iron phosphate, lithium manganese oxide and nickel-manganese-cobalt variants.

Looking ahead, the team plans to scale the process and consider ways it can sustain high efficiency for greater lithium hydroxide concentrations.

“We’ve made lithium extraction cleaner and simpler,” Biswal added in the release. “Now we see the next bottleneck clearly. Tackle concentration, and you unlock even better sustainability.
