The Department of Energy announced two major initiatives at U.S. Secretary of Energy Jennifer M. Granholm's address earlier this week at CERAWeek by S&P Global.

The first announcement Granholm revealed on Monday, March 18, at her keynote address was the DOE's latest Pathways to Commercial Liftoff report, which are initiatives established to provide investors with information of how specific energy technologies commercialize and what challenges they each have to overcome as they scale.

"We develop these Liftoff Reports through a combination of modeling and hundreds and hundreds of interviews with people across the whole investment lifecycle—from early-stage capital to commercial banks and institutional investors," Granholm says in her address.

The DOE has released eight already, and the ninth — and Granholm's favorite, she says — is on geothermal energy.

"Geothermal has such enormous potential. If we can capture the 'heat beneath our feet,' it can be the clean, reliable, base-load scalable power for everybody from industries to households," she says.

Geothermal development requires similar skills and infrastructure to traditional oil and gas, meaning the transition should be smooth, she explains, adding that the market is huge for geothermal.

"At scale, this market is significant: We're talking about at least—at least—a $250 billion investment opportunity to meet the goal that we have of 90 gigawatts of capacity by 2050," she remarks.

Granholm's address shifted into acknowledging the negative impact on communities the energy industry's history is paved with. She emphasizes how each of the Biden Administration's laws passed — like the Inflation Reduction Act and the Bipartisan Infrastructure Law — implemented requirements and incentives with communities in mind.

The administration's next initiative, and Granholm's second big announcement, is "to empower communities to build their energy future."

Regional Energy Democracy Initiative, or REDI, as Granholm describes, will "bring together companies, and community groups, and academic institutions, and philanthropy to weave equity and justice into DOE-funded clean energy projects."

The inaugural pilot will be in the Gulf South across Texas and Louisiana. She says the DOE plans to award over $8 billion to regional carbon reduction and clean energy infrastructure projects.

"These structures will provide capacity building, technical assistance to help communities match their most pressing needs with the biggest opportunities…to design and to implement Community Benefits Plans," Granholm says, "in short, really to have a say in how the historic clean energy investments in their backyards are going to benefit their people."

Granholm also noted on the progress of the clean energy sector, including how clean energy investment is three times what it was in 2018 and that in 2024, wind and solar energy in the U.S. is expected to outpace coal generation for the first time.

All this progress, Granholm explains, in light of global events and global energy supply disruption

"But our work together really has to extend beyond crisis management," she says. "Because the sooner that we acknowledge this transition for what it is—an undeniable, inevitable, and necessary realignment of the world’s energy system—the sooner we can capitalize on this incredible opportunity."

Houston AI energy forecasting company lands investment from Samsung Ventures

funding for forecasts

Amperon, a Houston-based AI-powered forecasting solutions company, has received an investment for an undisclosed amount from Samsung Ventures, the corporate venture arm of Samsung Group.

According to Amperon, the funding will be put toward the company's global growth and next-generation product development. Samsung Ventures invests in emerging businesses developing technologies for the AI, advanced devices and energy-related sectors.

“Samsung Ventures’ investment is a strong validation of our mission to transform the way energy is forecasted and traded,” Sean Kelly, CEO and co-founder of Amperon, said in a news release. “Samsung’s global footprint and leadership in semiconductors, data infrastructure, and AI acceleration make them a natural fit as we expand Amperon’s reach into energy-intensive sectors like data centers. Their track record of scaling next-generation technologies aligns perfectly with our vision to build a more intelligent, resilient, and data-driven energy system.”

Amperon was founded in 2018. Its AI models combine real-time weather, consumption and market data for energy retailers, utilities and independent power producers.

Last year, the company launched its weather-informed grid demand Mid-Term Forecast (MTF), which provides users with data on electricity demand up to seven months in advance. It also secured strategic investments from Acario, the corporate venture capital and innovation division of Tokyo Gas, as well as National Grid Partners, the venture investment and innovation arm of National Grid (NYSE: NGG).

After expanding into Europe in 2024, the company has continued to see international growth, and currently operates in the U.S., Canada, Mexico, Australia, Europe and the Middle East.

“Amperon has demonstrated strong technical capabilities and global traction in a rapidly evolving energy landscape,” a spokesperson for Samsung Ventures added in the release. “Their ability to forecast and model real-time energy data at global scale positions them as a key enabler of smarter energy systems and climate resilience. We are pleased to invest in a company developing technologies that support a more sustainable and digitized world.”

Solar surpasses coal to become ERCOT’s third-largest power source in 2025

by the numbers

Solar barely eclipsed coal to become the third biggest source of energy generated for the Electric Reliability Council of Texas (ERCOT) in 2025, according to new data.

In 2024, solar represented 10 percent of energy supplied to the ERCOT electric grid. Last year, that number climbed to 14 percent. During the same period, coal’s share remained at 13 percent.

From the largest to smallest share, here’s the breakdown of other ERCOT energy sources in 2025 compared with 2024:

  • Combined-cycle gas: 33 percent, down from 35 percent in 2024
  • Wind: 23 percent, down from 24 percent in 2024
  • Natural gas: 8 percent, down from 9 percent in 2024
  • Nuclear: 8 percent, unchanged from 2024
  • Other sources: 1 percent, unchanged from 2024

Combined, solar and wind accounted for 37 percent of ERCOT energy sources.

Looking ahead, solar promises to reign as the star of the ERCOT show:

  • An ERCOT report released in December 2024 said solar is on track to continue outpacing other energy sources in terms of growth of installed generating capacity, followed by battery energy storage.
  • In December, ERCOT reported that more than 11,100 megawatts of new generating capacity had been added to its grid since the previous winter. One megawatt of electricity serves about 250 homes in peak-demand periods. Battery energy storage made up 47 percent of the new capacity, with solar in second place at 40 percent.

The mix of ERCOT’s energy is critical to Texas’ growing need for electricity, as ERCOT manages about 90 percent of the electric load for the state, including the Houston metro area. Data centers, AI and population growth are driving heightened demand for electricity.

In the first nine months of 2025, Texas added a nation-leading 7.4 gigawatts of solar capacity, according to a report from data and analytics firm Wood Mackenzie and the Solar Energy Industries Association.

“Remarkable growth in Texas, Indiana, Utah and other states ... shows just how decisively the market is moving toward solar,” says Abigail Ross Hopper, president and CEO of the solar association.
