Renewable energy is evolving as the primary energy source for large data centers, according to a new report.

The 2026 Global Data Center Outlook from commercial real estate services giant JLL points out that the pivot toward big data centers being powered by renewable energy stems from rising electricity costs and tightening carbon reduction requirements. In the data center sector, renewable energy, such as solar and wind power, is expected to outcompete fossil fuels on cost, the report says.

The JLL forecast carries implications for the Houston area’s tech and renewable energy sectors.

As of December, Texas was home to 413 data centers, second only to Virginia at 665, according to Visual Capitalist. Dozens more data centers are in the pipeline, with many of the new facilities slated for the Houston, Austin, Dallas-Fort Worth and San Antonio areas.

Amid Texas’ data center boom, several Houston companies are making inroads in the renewable energy market for data centers. For example, Houston-based low-carbon energy supplier ENGIE North America agreed last May to supply up to 300 megawatts of wind power for a Cipher Mining data center in West Texas.

The JLL report says power, not location or cost, will become the primary factor in selecting sites for data centers due to multi-year waits for grid connections.

“Energy infrastructure has emerged as the critical bottleneck constraining expansion [of data centers],” the report says. “Grid limitations now threaten to curtail growth trajectories, making behind-the-meter generation and integrated battery storage solutions essential pathways for sustainable scaling.”

Behind-the-meter generation refers to onsite energy systems such as microgrids, solar panels and solar battery storage. The report predicts global solar capacity will expand by roughly 100 gigawatts between 2026 and 2030 to more than 10,000 gigawatts.

“Solar will account for nearly half of global renewable energy capacity in 2026, and despite its intermittent properties, solar will remain a key source of sustainable energy for the data center sector for years to come,” the report says.

Thanks to cost and sustainability benefits, solar-plus-storage will become a key element of energy strategies for data centers by 2030, according to the report.

“While some of this energy harvesting will be colocated with data center facilities, much of the energy infrastructure will be installed offsite,” the report says.

Other findings of the report include:

AI could represent half of data center workloads by 2030, up from a quarter in 2025.
The current five-year “supercycle” of data center infrastructure development may result in global investments of up to $3 trillion by 2030.
Nearly 100 gigawatts worth of new data centers will be added between 2026 and 2030, doubling global capacity.

“We’re witnessing the most significant transformation in data center infrastructure since the original cloud migration,” says Matt Landek, who leads JLL’s data center division. “The sheer scale of demand is extraordinary.”

Hyperscalers, which operate massive data centers, are allocating $1 trillion for data center spending between 2024 and 2026, Landek notes, “while supply constraints and four-year grid connection delays are creating a perfect storm that’s fundamentally reshaping how we approach development, energy sourcing, and market strategy.”

Expert shares 5 key factors for evolving the energy transition in Texas

GUEST COLUMN

Humanity faces an inflection point in the coming decade. In order for the world’s population to survive and, ultimately, prosper, especially the population of developing countries such as India, China, and Brazil, significant investment in all forms of energy will be needed. Texas-based energy companies will play a crucial role in developing, advancing and supplying environmentally sensitive forms of energy to meet the world’s insatiable demand.

According to the U.S. Energy Information Administration, global energy consumption is expected to increase by a staggering 50 percent in the next 25 years. Fueled by rapid economic and population growth, this spike in demand is particularly focused within developing Asian countries outside of the Organization for Economic Cooperation and Development (OECD). Taking steps toward energy evolution today is crucial not only for economic progress but also to address the long-term impact of climate change. Research compiled by JLL highlights five key factors to consider.

1. Embracing a gradual evolution

Historically, energy transitions require significant time to be fully realized, often spanning over 50 years. Coal took more than 60 years to grow from a mere 5 percent to a dominant 50 percent share of the world's primary energy supply. Similarly, natural gas took nearly 70 years to increase its market share from 1 percent to 20 percent in the United States. Widespread commercialization of nuclear energy spans as much as 80 years, from the point of initial discovery and application. Major pendulum swings do not occur overnight; the next energy evolution will require adaptability and resilience.

2. Increase in global energy consumption

As non-OECD countries experience periods of economic growth, particularly driven by a growth of the manufacturing sector, these countries’ energy consumption naturally follows suit. Approximately 2.5 billion people live in these regions, which today heavily rely on non-renewable sources to meet basic energy needs.

As OECD countries continue to introduce sustainable technologies like battery power and other alternatives at scale, a transfer of more efficient and eco-friendly sources and technologies to developing communities must occur to reduce the world’s overall carbon footprint.

3. Surging investment in global energy transition

Investments in the global energy transition surpassed $1 trillion in 2022 – a stunning year-over-year increase of 31 percent. These investments are propelling innovative, sustainable solutions and driving the research and development necessary for a more environmentally conscious energy landscape.

4. Diversification and revised renewables forecast

Countries are actively diversifying their energy generation away from natural gas, specifically as a response to the energy crisis sparked by Russia's invasion of Ukraine. This push towards sustainable alternatives has received further validation with the International Energy Agency (IEA) recently revising its five-year renewables forecast, emphasizing a significant 28.4 percent increase. This revision serves as a testament to the increasing significance of sustainable energy sources in ensuring a resilient energy future.

5. United States energy production

Even with the implementation of the Inflation Reduction Act of 2022 (IRA), the United States will maintain its production and export of oil, natural gas, and derivatives. While recognizing the continued role of these traditional energy sources in meeting global energy demands, the United States also acknowledges the imperative of transitioning towards sustainable energy sources. Encouraging companies to embrace alternative energy solutions in line with this transition is now big business, as significant incentives are being provided at federal and state levels.

And what about here in Texas?

In this critical era of global energy evolution, Texas has the opportunity to take center stage, holding the keys not only to its own future but also to those far beyond the state’s borders. With abundant wind power production, vast solar energy potential, a favorable regulatory environment, and attractive tax incentives, Texas is well positioned to be a leader in innovation, research, and production of alternative energy sources. Combined with the presence of many of the country’s leading energy companies, Texas must be a powerhouse for driving a sustainable energy transition on a large scale.

Transforming the global energy landscape will not be accomplished overnight. It requires the collective efforts of governments, industries, companies, and individuals working together towards a common goal. Texas and Texans can serve as a beacon of inspiration, leading the charge in alternative energy adoption and investing today in the next century of energy production and consumption. Ultimately, our example should be one the world can follow.

The new projects will include one wind and two solar projects in Texas.

“The continued growth of our relationship with Ares reflects the strength of ENGIE’s portfolio of assets and our track record of delivering, operating and financing growth in the U.S. despite challenging circumstances,” Dave Carroll, CEO and Chief Renewables Officer of ENGIE North America, said in a news release. “The addition of another 730 MW of generation to our existing relationship reflects the commitment both ENGIE and Ares have to meeting growing demand for power in the U.S. and our willingness to invest in meeting those needs.”

ENGIE has more than 11 gigawatts of renewable energy projects in operation or under construction in the U.S. and Canada, and 52.7 gigawatts worldwide. The company is targeting 95 gigawatts by 2030.

ENGIE launched three new community solar farms in Illinois since December, including the 2.5-megawatt Harmony community solar farm in Lena and the Knox 2A and Knox 2B projects in Galesburg.

The company's 600-megawatt Swenson Ranch Solar project near Abilene, Texas, is expected to go online in 2027 and will provide power for Meta, the parent company of social media platform Facebook. Late last year, ENGIE also signed a nine-year renewable energy supply agreement with AstraZeneca to support the pharmaceutical company’s manufacturing operations from its 114-megawatt Tyson Nick Solar Project in Lamar County, Texas.

Houston geothermal company raises $97M Series B

fresh funding

Houston-based geothermal energy startup Sage Geosystems has closed its Series B fundraising round and plans to use the money to launch its first commercial next-generation geothermal power generation facility.

Ormat Technologies and Carbon Direct Capital co-led the $97 million round, according to a press release from Sage. Existing investors Exa, Nabors, alfa8, Arch Meredith, Abilene Partners, Cubit Capital and Ignis H2 Energy also participated, as well as new investors SiteGround Capital and The UC Berkeley Foundation’s Climate Solutions Fund.

The new geothermal power generation facility will be located at one of Ormat Technologies' existing power plants. The Nevada-based company has geothermal power projects in the U.S. and numerous other countries around the world. The facility will use Sage’s proprietary pressure geothermal technology, which extracts geothermal heat energy from hot dry rock, an abundant geothermal resource.

“Pressure geothermal is designed to be commercial, scalable and deployable almost anywhere,” Cindy Taff, CEO of Sage Geosystems, said in the news release. “This Series B allows us to prove that at commercial scale, reflecting strong conviction from partners who understand both the urgency of energy demand and the criticality of firm power.”

Sage reports that partnering with the Ormat facility will allow it to market and scale up its pressure geothermal technology at a faster rate.

“This investment builds on the strong foundation we’ve established through our commercial agreement and reinforces Ormat’s commitment to accelerating geothermal development,” Doron Blachar, CEO of Ormat Technologies, added in the release. “Sage’s technical expertise and innovative approach are well aligned with Ormat’s strategy to move faster from concept to commercialization. We’re pleased to take this natural next step in a partnership we believe strongly in.”

In 2024, Sage agreed to deliver up to 150 megawatts of new geothermal baseload power to Meta, the parent company of Facebook. At the time, the companies reported that the project's first phase would aim to be operating in 2027.

The company also raised a $17 million Series A, led by Chesapeake Energy Corp., in 2024.

Houston expert discusses the clean energy founder's paradox

Guest Column

Everyone tells you to move fast and break things. In clean energy, moving fast without structural integrity means breaking the only planet we’ve got. This is the founder's paradox: you are building a company in an industry where the stakes are existential, the timelines are glacial, and the capital requires patience.

The myth of the lone genius in a garage doesn’t really apply here. Clean energy startups aren’t just fighting competitors. They are fighting physics, policy, and decades of existing infrastructure. This isn’t an app. You’re building something physical that has to work in the real world. It has to be cheaper, more reliable, and clearly better than fossil fuels. Being “green” alone isn’t enough. Scale is what matters.

Your biggest risks aren’t competitors. They’re interconnection delays, permitting timelines, supply chain fragility, and whether your first customer is willing to underwrite something that hasn’t been done before.

That reality creates a brutal filter. Successful founders in this space need deep technical knowledge and the ability to execute. You need to understand engineering, navigate regulation, and think in terms of markets and risk. You’re not just selling a product. You’re selling a future where your solution becomes the obvious choice. That means connecting short-term financial returns with long-term system change.

The capital is there, but it’s smarter and more demanding. Investors today have PhDs in electrochemistry and grid dynamics. They’ve been burned by promises of miracle materials that never left the lab. They don't fund visions; they fund pathways to impact that can scale and make financial sense. Your roadmap must show not just a brilliant invention, but a clear, believable plan to drive costs down over time.

Capital in this sector isn’t impressed by ambition alone. It wants evidence that risk is being retired in the right order — even if that means slower growth early.

Here’s the upside. The difficulty of clean energy is also its strength. If you succeed, your advantage isn’t just in software or branding. It’s in hardware, supply chains, approvals, and years of hard work that others can’t easily copy. Your real competitors aren’t other startups. They’re inertia and the existing system. Winning here isn’t zero-sum. When one solution scales, it helps the entire market grow.

So, to the founder in the lab, or running field tests at a remote site: your pace will feel slow. The validation cycles are long. But you are building in the physical world. When you succeed, you don’t have an exit. You have a foundation. You don't just have customers; you have converts. And the product you ship doesn't just generate revenue; it creates a legacy.

If your timelines feel uncomfortable compared to software, that’s because you’re operating inside a system designed to resist change. And let’s not forget you are building actual physical products that interact with a complex world. Times are tough. Don’t give up. We need you.
