EnergyRe, a developer of large-scale renewable energy projects with headquarters in Houston and New York, has signed a renewable energy agreement that will allow Google to invest in and purchase renewable energy credits (RECs) from its projects under development in South Carolina.

Google will be able to pull from energyRe’s portfolio of more than 600 megawatts of new solar and solar storage projects in the state.

The agreement marks the second partnership between the companies. Last year, energyRe and Google signed a 12-year power purchase agreement in which Google would purchase renewable energy from a 435-megawatt solar project. EnergyRe would supply electricity and RECs generated from the solar project to Google to power the equivalent of more than 56,000 homes.

"Strengthening the grid by deploying more reliable and clean energy is crucial for supporting the digital infrastructure that businesses and individuals depend on," Amanda Peterson Corio, head of data center energy at Google, said in a news release. "Our collaboration with energyRe will help power our data centers and the broader economic growth of South Carolina."

EnergyRe's work includes developing high-voltage transmission, onshore and offshore wind, large-scale solar, distributed generation and storage assets in markets around the United States. Its national onshore utility-scale portfolio includes 1,520 megawatts of contracted solar assets and 398 megawatt-hours of contracted battery storage assets.

"This agreement is a milestone in energyRe's mission to develop innovative and impactful clean energy solutions for the future," Miguel Prado, CEO of energyRe, added in the news release."We're honored to partner with Google to help advance their ambitious sustainability and decarbonization objectives while delivering dependable, locally sourced clean energy to meet growing energy demands."

Google aims to achieve net-zero carbon emissions across its operations and value chain by 2030.

Harris County looks to future with new Climate Justice Plan

progress plan

Harris County commissioners approved a five-point Climate Justice Plan last month with a 3-1 vote by Harris County commissioners. The plan was created by the Office of County Administration’s Office of Sustainability and the nonprofit Coalition for Environment, Equity and Resilience.

“Climate action planning that centers on justice has the potential to spark innovative thinking and transformative actions that will lead to meaningful and just transitions in communities, policies, funding mechanisms, and implementation strategies,” the 59-page report reads.

The plan seeks to address issues relating to ecology, infrastructure, economy, community and culture. Here’s a breakdown:

Ecology

The plan will work towards clean air, water, and soil efforts that support the health of the environment, renewable energy that reduces greenhouse gases and pollution, and conservation and protection of our natural resources. Some action items include:

Increasing resources for local government agencies
Developing a free native seed bank at all libraries
Identifying partners and funding streams to reduce the costs of solar power for area households
Producing renewable energy on large tracts of land
Expanding tree planting by 20 percent
Providing tree maintenance and restoration efforts
Incentivizing gray water systems and filtration to conserve fresh water

Economy

In terms of the economy, the Climate Justice Plan wants the basic needs of the community met and wants to also incentivize resilience, sustainability, and climate solutions, and recycling and reuse methods. Specific actions include:

Quantifying the rising costs associated with climate change
Expanding resources and partnering with organizations to support programs that provide food, utility, housing, and direct cash assistance
Supporting a coalition of area non-profit organizations and county offices to strengthen social service support infrastructure
Supporting home repair, solar installation, and weatherization programs
Identify methods to expand free and efficient recycling and composting services
Creating a climate tax levied on greenhouse gas emissions to develop a climate fund to offset the impacts of pollution

Infrastructure

As Houston has been prone to hurricanes and flooding damage, the infrastructure portion of the plan aims to protect the region from risks through preventative floodplain and watershed management. Highlights include:

Investing in generators and solar power, plus battery backup and bidirectional EV charging for all county libraries
Providing more heating and cooling centers with charging stations
Coordinating and deploying community microgrids, especially in neighborhoods prone to losing power
Seeking partnerships and funding for low- or no-cost water purifiers for areas with the highest needs
Protecting the electric grid through regular maintenance and upgrading, and advocating for greater accountability and responsiveness among appointed officials
Developing regulations to require resilient power line infrastructure to prevent outages and failures in new developments

Community and Culture

Housing, a strong economy and access to affordable and healthy food will be achieved under the community aspect of the plan. Under culture, the plan seeks to share knowledge and build trust. Key goals include:

Developing a campaign to promote the use of the Harris County 311 system to identify critical community concerns
Supporting the development of a Community Housing Plan that ensures stable and safe housing
Advocating for revisions to Federal Emergency Management Agency (FEMA) disaster funding to account for renters’ losses and unmet housing needs
Developing and funding a whole-home program for repairs, weatherization, and solar energy
Developing culturally relevant public relations campaigns to increase knowledge of health, environment and biodiversity across generations

Houston unveils details for first-of-its-kind art installation that generates clean energy

power of art

Local and state leaders shared updated plans this month on a first-of-its-kind structure that uses art to generate solar energy.

Slated to be located at Mason Park in Houston’s East End, the new "Arch of Time" is a freestanding sundial art installation that will generate 400,000 kilowatt-hours of power per year using 60,000 solar photovoltaic cells on its south-facing exterior.

The project will be part of a larger pavilion at the park and is being led by the renewable energy organization Land Art Generator Initiative (LAGI). Architect Riccardo Mariano will design the space. It will be funded by donations and cost $20 million, organizers say.

The project, originally known as "Arco del Tiempo," was announced in 2023. At the time, the city shared the installation would be installed at Guadalupe Plaza Park in 2024.

The project's latest update was announced during Houston City Hall’s Earth Day 2025, where organizers described it as "a monument to Houston's past, present, and future leadership as the energy capital of the world."

The 100-foot structure will also serve as a 25,000-square-foot shaded area, or microclimate, during hot days. It will also feature a stage performance space and a power hub for emergencies. Due to the artwork's north opening and south narrowing, it is also expected to help channel the breezes, according to LAGI.

The organization says it is also expected to generate enough power to fuel all of Mason Park.

“Mason Park will soon, perhaps become the first major park in the country that is powered entirely by the sun,” Houston City Council Member Joaquin Martinez said at the news conference. “The economic benefits are clear.”

Former Houston Park and Recreation director Joe Turner selected the East End park as the location of the arch and believes it could be used as a STEM tool for students.

“All the STEM education that can come from the way we use the solar collectors, the way it has a water collection system that's going to collect the runoff water, there's so much we can do to teach kids STEM,” said in a Houston Park and Recreation Department video.

The project is about two years away from being completed. LAGI says the Arch of Time will be the “first public art project of its scale to stand as a net-positive contribution to a sustainable climate.”

What is the future of "the fifth utility"? Getty Images

Experts on U.S. energy infrastructure, sustainability, and the future of data

Guest column

Digital infrastructure is the dominant theme in energy and infrastructure, real estate and technology markets.

Data, the byproduct and primary value generated by digital infrastructure, is referred to as “the fifth utility,” along with water, gas, electricity and telecommunications. Data is created, aggregated, stored, transmitted, shared, traded and sold. Data requires data centers. Data centers require energy. The United States is home to approximately 40% of the world's data centers. The U.S. is set to lead the world in digital infrastructure advancement and has an opportunity to lead on energy for a very long time.

Data centers consume vast amounts of electricity due to their computational and cooling requirements. According to the United States Department of Energy, data centers consume “10 to 50 times the energy per floor space of a typical commercial office building.” Lawrence Berkeley National Laboratory issued a report in December 2024 stating that U.S. data center energy use reached 176 TWh by 2023, “representing 4.4% of total U.S. electricity consumption.” This percentage will increase significantly with near-term investment into high performance computing (HPC) and artificial intelligence (AI). The markets recognize the need for digital infrastructure build-out and, developers, engineers, investors and asset owners are responding at an incredible clip.

However, the energy demands required to meet this digital load growth pose significant challenges to the U.S. power grid. Reliability and cost-efficiency have been, and will continue to be, two non-negotiable priorities of the legal, regulatory and quasi-regulatory regime overlaying the U.S. power grid.

Maintaining and improving reliability requires physical solutions. The grid must be perfectly balanced, with neither too little nor too much electricity at any given time. Specifically, new-build, physical power generation and transmission (a topic worthy of another article) projects must be built. To be sure, innovative financial products such as virtual power purchase agreements (VPPAs), hedges, environmental attributes, and other offtake strategies have been, and will continue to be, critical to growing the U.S. renewable energy markets and facilitating the energy transition, but the U.S. electrical grid needs to generate and move significantly more electrons to support the digital infrastructure transformation.

But there is now a third permanent priority: sustainability. New power generation over the next decade will include a mix of solar (large and small scale, offsite and onsite), wind and natural gas resources, with existing nuclear power, hydro, biomass, and geothermal remaining important in their respective regions.

Solar, in particular, will grow as a percentage of U.S grid generation. The Solar Energy Industries Association (SEIA) reported that solar added 50 gigawatts of new capacity to the U.S. grid in 2024, “the largest single year of new capacity added to the grid by an energy technology in over two decades.” Solar is leading, as it can be flexibly sized and sited.

Under-utilized technology such as carbon capture, utilization and storage (CCUS) will become more prominent. Hydrogen may be a potential game-changer in the medium-to-long-term. Further, a nuclear power renaissance (conventional and small modular reactor (SMR) technologies) appears to be real, with recent commitments from some of the largest companies in the world, led by technology companies. Nuclear is poised to be a part of a “net-zero” future in the United States, also in the medium-to-long term.

The transition from fossil fuels to zero carbon renewable energy is well on its way – this is undeniable – and will continue, regardless of U.S. political and market cycles. Along with reliability and cost efficiency, sustainability has become a permanent third leg of the U.S. power grid stool.

Sustainability is now non-negotiable. Corporate renewable and low carbon energy procurement is strong. State renewable portfolio standards (RPS) and clean energy standards (CES) have established aggressive goals. Domestic manufacturing of the equipment deployed in the U.S. is growing meaningfully and in politically diverse regions of the country. Solar, wind and batteries are increasing less expensive. But, perhaps more importantly, the grid needs as much renewable and low carbon power generation as possible - not in lieu of gas generation, but as an increasingly growing pairing with gas and other technologies. This is not an “R” or “D” issue (as we say in Washington), and it's not an “either, or” issue, it's good business and a physical necessity.

As a result, solar, wind and battery storage deployment, in particular, will continue to accelerate in the U.S. These clean technologies will inevitably become more efficient as the buildout in the U.S. increases, investments continue and technology advances.

At some point in the future (it won’t be in the 2020s, it could be in the 2030s, but, more realistically, in the 2040s), the U.S. will have achieved the remarkable – a truly modern (if not entirely overhauled) grid dependent largely on a mix of zero and low carbon power generation and storage technology. And when this happens, it will have been due in large part to the clean technology deployment and advances over the next 10 to 15 years resulting from the current digital infrastructure boom.

Houston oil and gas producer expands into renewables, announces new Baytown facility

Renewables News

Houston American Energy Corp. (NYSE: HUSA), an oil and gas exploration and production company, has entered into a definitive agreement to acquire New York-based Abundia Global Impact Group LLC, which specializes in converting waste into high-value fuels and chemicals.

HUSA is expected to close on the AGIG acquisition early in the second quarter and says the deal aims to provide value through “innovation in the renewable energy sector,” according to a news release.

As part of the deal, HUSA will acquire 100% of AGIG’s issued and outstanding units. HUSA will also issue to AGIG’s members a number of shares of HUSA common stock that will equal 94 percent of HUSA’s aggregate issued and outstanding common stock at the time of the closing. The company also closed a $4.42 million registered direct offering in January.

“AGIG has developed a commercially ready project for converting waste into valuable fuels and chemicals, and this transaction gives HUSA shareholders a ready-made platform and project pipeline for future value generation,” Peter Longo, CEO of Houston American Energy Corp, said in a news release. “We are witnessing the growing momentum of the fuel and chemical industry’s transformation into alternative solutions like recycled chemical alternatives and the highly publicized sustainable aviation fuel market.”

AGIG will build its first advanced plastic recycling facility in the Cedar Port Industrial Park in the Baytown area of Houston. The facility will represent the first phase of a growth plan aimed at scaling AGIG’s technologies for producing renewable fuels and chemicals from waste, according to the company. The Cedar Port facility will serve as a hub for a five-year development plan and will be designed to scale production capacity.

"We are excited to use this platform to support the deployment and development of our suite of technologies that will assist in the evolution of fuel, chemical and waste markets, providing commercial alternatives and sustainable products,” AGIG CEO Ed Gillespie said in a news release.

Solar farms are booming and putting thousands of hungry sheep to work

Solar Power

On rural Texas farmland, beneath hundreds of rows of solar panels, a troop of stocky sheep rummage through pasture, casually bumping into one another as they remain committed to a single task: chewing grass.

The booming solar industry has found an unlikely mascot in sheep as large-scale solar farms crop up across the U.S. and in the plain fields of Texas. In Milam County, outside Austin, SB Energy operates the fifth-largest solar project in the country, capable of generating 900 megawatts of power across 4,000 acres.

How do they manage all that grass? With the help of about 3,000 sheep, which are better suited than lawnmowers to fit between small crevices and chew away rain or shine.

The proliferation of sheep on solar farms is part of a broader trend — solar grazing — that has exploded alongside the solar industry.

Agrivoltaics, a method using land for both solar energy production and agriculture, is on the rise with more than 60 solar grazing projects in the U.S., according to the National Renewable Energy Laboratory. The American Solar Grazing Association says 27 states engage in the practice.

"The industry tends to rely on gas-powered mowers, which kind of contradicts the purpose of renewables," SB Energy asset manager James Hawkins said.

A sunny opportunity
Putting the animals to work on solar fields also provides some help to the sheep and wool market, which has struggled in recent years. The inventory of sheep and lamb in Texas fell to 655,000 in January 2024, a 4% drop from the previous year, according to the most recent figures from the U.S. Department of Agriculture.

Because solar fields use sunny, flat land that is often ideal for livestock grazing, the power plants have been used in coordination with farmers rather than against them.

Sheepherder JR Howard accidentally found himself in the middle of Texas' burgeoning clean energy transition. In 2021, he and his family began contracting with solar farms — sites with hundreds of thousands of solar modules — to use his sheep to eat the grass.

What was once a small business has turned into a full-scale operation with more than 8,000 sheep and 26 employees.

"Just the growth has been kind of crazy for us," said Howard, who named his company Texas Solar Sheep. "It's been great for me and my family."

Following the herd
Some agriculture experts say Howard's success reflects how solar farms have become a boon for some ranchers.

Reid Redden, a sheep farmer and solar vegetation manager in San Angelo, Texas, said a successful sheep business requires agricultural land that has become increasingly scarce.

"Solar grazing is probably the biggest opportunity that the sheep industry had in the United States in several generations," Redden said.

The response to solar grazing has been overwhelmingly positive in rural communities near South Texas solar farms where Redden raises sheep for sites to use, he said.

"I think it softens the blow of the big shock and awe of a big solar farm coming in," Redden said.

Fielding more research
Agrivoltaics itself isn't new. Solar farms are land-intensive and require a lot of space that could be used for food production. Agrivoltaics compensates by allowing the two to coexist, whether growing food or caring for livestock.

There is a lot still unknown about the full effects of solar grazing, said Nuria Gomez-Casanovas, an assistant professor in regenerative system ecology at Texas A&M University.

Not enough studies have been done to know the long-term environmental impacts, such as how viable the soil will be for future agriculture, although Gomez-Casanovas suspects solar grazing may improve sheep productivity because the panels provide shade and can be more cost-efficient than mowing.

"We really have more questions than answers," Gomez-Casanovas said. "There are studies that show that the land productivity is not higher versus solar alone or agriculture alone, so it's context-dependent."

As one of Texas' largest solar sheep operators, Howard has more clients than he can handle. He expects to add about 20 more employees by the end of this year, which would nearly double his current workforce. As for the sheep, he has enough already.
