Houston entrepreneur launches new venture to shine light on sustainability

A Houston nuclear engineer and entrepreneur wants consumers to capture their own ray of sunlight to brighten the prospect of making clean energy a bigger part of the power grid.

Solar Slice Founder Nathan Childress says his new venture offers a fulfilling way to encourage and promote solar energy and a greener planet. An experienced entrepreneur, Childress also serves as founder and CEO of technology software company Macorva.

Although trained in nuclear power plant design, solar power drew his interest as a cheaper and more accessible alternative, and Childress tells InnovationMap that he thinks that the transition to cleaner energy, in Texas especially, needs to step up.

With energy demand skyrocketing, and the push toward renewable solutions, solar seems like a safe bet for Childress, a former competitive high-stakes poker player. Childress cites a recent Yale University study that says 63 percent of Americans “feel a personal responsibility to help reduce global warming.”

But some studies show that 80 to 90 percent of the money invested into fighting climate change “aren’t going to things that people actually consider helpful,” he says.

“They’re more just projects that sound good, that are not actually taking any action,” says Childress, who has called Houston home for 25 years. He received his doctorate in medical physics at M.D. Anderson Cancer Center, where he worked on software that provided radiation therapy for patients.

The initial Kickstarter fundraising round, which will be launched soon, will finance the construction of one utility-scale solar farm, on about five to 10 acres, which would produce about 1 megawatt, or 1,000 kilowatts, of clean energy. The plant would make enough energy to power about 200 average homes.

Childress says interest has been strong, with several thousand signed up on the Kickstarter launch list. Some who are signed up expressed interest in a subscription, he said, and that may be offered later. Initially, though, for a one-time purchase of $95, a Solar Slice client can purchase one virtual 50W slice of solar power, produced by the farm. Over its lifetime, Childress says, that one purchase can offset three tons of carbon dioxide.

The app tracks carbon offsetting, and energy production for the slice, showing a client “exactly how much I have helped the climate, here’s exactly how (many) emissions I have prevented from putting in the atmosphere,” he says.

The energy produced by five slices can offset the average American’s carbon footprint for a year, and the power generated by the solar farm will be sold to the electric grid. As clients purchase more slices, they can earn eco-credits to donate to other climate-friendly partners, to plant trees or create pollinator habitats.

While Solar Slice is a for-profit venture, contributors won’t get rich or even make money from their purchase. Rather, it provides validation.

“Our focus is maximizing the real world impact, not for financial gain. This is not something people sign up (for) to make money. We’re really clear about that,” Childress says. “I want to show that it’s possible to have a for-profit company that is sustainable, that does good work.

“And hopefully, we can be part of the spirit…for a bigger movement, and for consumers and business, especially, to do things that matter.”

The largest U.S. solar plants are in Nevada and California, and those states are sites under consideration, but Childress says Texas is the most likely home for the initial project. The ten largest utility-scale solar plants in Texas by capacity are all in far west or central parts of the state, according to the state comptroller’s office.

Childress has a team of four, who are handling the marketing, plant design and site scouting, and hopes to hire five to 10 more, depending on response and growth. He says the Solar Slice consumer can directly connect in real time to the contribution that their purchase will make toward a green energy future.

“That was our inspiration..let’s start something that is really making a difference..and making really clear to the individuals what’s being done,” he says.

Solar energy has become a growing source of power for Texas, comprising about 6 percent of the state’s energy generation, as of 2022, the comptroller’s office says.

The state ranks first in projected growth of solar energy over the next five years, with more than 9,500 operating solar plants, and many thousands more announced, according to the state Public Utility Commission.

“We would absolutely love to make this into something where we are building plants around the nation, around the world,” Childress he says.

However, resistance to alternative energy projects like solar and wind, especially on a large scale, remains in some quarters.

Obtaining site permits for swaths of land can be also a challenge. For example, a recent survey by Berkeley Lab of 123 professionals from 62 unique, large-scale wind and solar energy facilities showed that about one-third of wind and solar siting applications in the past five years were canceled.

Half of the projects experienced delays of six months or longer. And according to the survey, developers expect the trend to continue, and become more expensive to address.

However, another Berkeley Lab survey of residents who live within three miles of a solar power plant showed that most view the plant positively. The larger the plant, the more negative the response in the survey. The smaller the farm, the more positive the reactions.

Childress says many of the common objections to utility-scale solar farms are misguided, and incorrect. For example, the concern that they would take over available farmland or take up too much space.

He says that even if the entire U.S. power grid relied solely on solar power, the plants would occupy not even a half percent of available land, which is about one percent farmland.

Houston-based NRG Energy Inc. announced Jan. 7 that it has appointed Robert J. Gaudette as president and CEO. Gaudette took over as president effective Jan. 7 and will assume the role of CEO April 30, coinciding with the company's next stockholder meeting.

Gaudette, who previously served as executive vice president and president of NRG Business and Wholesale Operations, will succeed Lawrence Coben in the leadership roles. Coben will remain an advisor to NRG through the end of the year and will also continue to serve as board chair until April 30. Antonio Carrillo, lead independent director at NRG, will take over as board chair.

"Rob has played a central role in strengthening NRG’s position as a leader in our industry through strategic growth, operational excellence, and customer-focused innovation," Coben said in the news release. "He is a strong, decisive leader with extensive knowledge of our business, markets, and customers. The Board and I are confident that Rob is the right person to lead NRG forward and take the NRG rocket ship to new heights. I can’t wait to see what comes next.”

Gaudette has been with NRG since 2001. He has served as EVP of NRG Business and Market Operations since 2022 and president of NRG Business and Market Operations since 2024. In these roles, he led NRG’s power generation and oversaw its portfolio of commercial and industrial products and services as well as its market operations, according to the company.

He has held various executive leadership roles at NRG. He earned his bachelor's degree in chemistry from The College of William and Mary and an MBA at Rice University, where he was a Jones Scholar. He also served four years as an Army officer.

“It is an honor to be appointed NRG’s next CEO at this transformative time for the energy sector and our company,” Gaudette said in the release. “With NRG’s electricity, natural gas and smart home portfolio, we are ideally positioned to meet America’s evolving energy needs. I am grateful to Larry and all my NRG colleagues, both past and present, who built our great company and positioned us for the future. I look forward to leading our incredible team to deliver affordable, resilient power for the customers and communities we serve, while creating substantial value for our shareholders.”

In addition to its traditional power generation and electricity businesses, NRG has been working to develop a 1-gigawatt virtual power plant by connecting thousands of decentralized energy sources by 2035 in an effort to meet Texas’ surging energy demands.

The company announced partnerships last year with two California-based companies to bolster home battery use and grow its network. NRG has said the VPP could provide energy to 200,000 homes during peak demand.
