Houston Independent School District is hopping on the city's net-zero carbon emissions bus, so to speak, thanks to more than $6.2 million in funding that came from the Environmental Protection Agency last year.

The funds are part of the EPA's Clean School Bus Program Fiscal Year 2022 rebate competition, which will award nearly $51 million in funds from President Biden’s Bipartisan Infrastructure Law to Texas school districts, and $965 million in total to districts around the country.

Houston's $6.2 million will go toward 25 new school buses, according to a statement from the EPA. Fifteen of the vehicles will be brand-new electric buses.

"Taking steps to make our school buses greener while remaining safe and effective is not only imperative for the wellbeing of students and bus drivers, but also for the public at large,” Houston Congressman Al Green said in a statement. “I applaud this announcement by the EPA under President Biden’s leadership. I look forward to seeing the positive impact that this outstanding award to purchase electric and propane school buses will have on reducing our carbon footprint.”

HISD's next step was to submit Payment Request Forms with purchase orders that shows the district has ordered the new buses and eligible infrastructure.

The district is among 13 Texas school districts to receive funding. Dallas ISD, the second largest school district in the state behind HISD, was awarded roughly $7.6 million. Killeen ISD and Socorro ISD received the largest sums among the districts, totalling nearly $9.9 million in funding each.

At the time of the statement from October, the EPA had selected 389 applications across the country totaling $913 million to support the purchase of 2,463 buses, mainly in areas serving low-income, rural, and/or Tribal students. More applications are under review, and the EPA plans to announce additional districts that will receive funding, bringing the total investment to the full $965 million, in the coming weeks, according to a statement.

The EPA intends to make available another $1 billion for clean school buses in Fiscal Year 2023.

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.
