Texas has room to improve when it comes to energy efficiency, recent data from WalletHub shows.

The personal finance website ranked Texas at No. 35 on the latest Most & Least Energy-Efficient States list. Texas improved by one spot on the 2025 report, after coming in at No. 36 last year.

The report measured and ranked the efficiency of auto energy and home energy consumption in the 48 U.S. mainland states based on data from the U.S. Census Bureau, National Climatic Data Center, U.S. Energy Information Administration and the U.S. Department of Transportation – Federal Highway Administration.

Texas earned an overall score of 50.60. It was ranked No. 27 for home energy efficiency and No. 41 for auto efficiency. By comparison, No. 1-ranked Vermont earned a score of 85.30, ranking No. 2 for home energy and No. 6 for out energy.

The top five overall states included:

  • No. 1 Vermont
  • No. 2 California
  • No. 3 Washington
  • No. 4 New York
  • No. 5 Massachusetts

South Dakota earned the top rank for home energy efficiency, and Massachusetts earned the top rank for energy efficiency.

“Energy efficiency doesn’t just help save the planet – it also helps save you money by lowering the amount of electricity, gas, oil or other types of energy you need to consume. While there are some steps you can take to become more energy-efficient on your own, living in the right area can give you a big boost," WalletHub analyst Chip Lupo said in the report. "For example, certain states have much better public transportation systems that minimize your need to drive, at least in big cities. Some places also have better-constructed buildings that retain heat better during the winter or stay cooler during the summer.”

According to the report, some progress is being made in increasing energy efficiency across the country. The U.S. Energy Information Administration expects 26 percent of electricity generation in 2026 will come from renewables. A number of them are being developed in the Houston area, including recent announcements like the Pleasure Island Power Collective in Port Arthur.

Still, Houston earned an abysmal ranking on WalletHub's greenest cities in the U.S. report earlier this year, coming in at No. 99 out of 100. Read more here.

Op-Ed: To protect the Texas grid, help Texans protect themselves

guest column

On the evening of May 16, a devastating “derecho” storm howled through Houston. Nearly 800,000 customers lost power. Many were still without electricity days later, as a heat wave baked neighborhoods that couldn’t power air conditioners.

It was yet another unwelcome reminder about the precariousness of the power grid.

These outages followed repeated grid warnings, conservation calls, and near-misses last summer and the summer before, as well as the catastrophic Winter Storm Uri freeze in February 2021.

The outages also preceded the increasingly extreme weather Texas faces and staggering growth on the ERCOT grid: after growing about 1 percent a year for 20 years, the power grid covering most of Texas may need to be 78 percent bigger by 2030.

So, this latest incident is more than a sign that Houstonians must take control of their power. It also shows that more and more, the state needs you to act.

Like any other market, a power grid runs on supply and demand. The supply of Texas energy is growing, which is great. At the same time, the economy is booming, leaving Texas setting demand records almost constantly. Generators can’t always keep up, especially when power plants break down or don’t produce electricity — there’s about an 18 percent chance that Texas will face at least one grid emergency this summer.

With odds like that, it’s no wonder that more and more Texans are finding ways to live more powerfully. Many are investing in solar panels and energy storage devices like Tesla Powerwalls.

These systems let families and business owners generate electricity during the day, store it, and use it later when there’s an emergency or just when power is scarce. They protect people from high bills and blackouts; it’s no coincidence that just since last month's storm, we've seen a five-fold increase in leads, reflecting a huge growth in interest in solar power. Further, since the storm, 90 percent of new Houston-area solar customers have bought backup battery systems, compared to 50 percent in 2024 and less than 25 percent in 2023.

That pattern has repeated across the country after severe weather events.

Homeowners and business owners can also slash their bills by weatherizing houses and buildings, the way power plants did after Uri. Advanced devices that help people automatically, and voluntarily, reduce electricity use when the grid is stretched would also help.

These improvements and investments would help more than just homeowners and business owners — they’d help the entire power grid. Every kilowatt that someone doesn’t need or can generate themselves frees up power for other families and businesses across the grid. That helps Texas keep the lights on, especially if electricity demand is about to spike as dramatically as the state expects.

Texas already incentivizes conservation and generation at a large scale. For example, large users like manufacturers and crypto miners get paid by ERCOT for reducing electricity use when the grid is stretched. And just last year, the legislature passed a $10 billion program to help fund new gas power plants.

It’s past time to extend similar incentives to everyday Texans, especially when we’re increasingly called upon to help ERCOT keep the lights on.

If crypto companies get money for reducing electricity use when ERCOT asks them to, then residential and business customers deserve to get paid too. The state could help Texans invest in technologies and smart metering programs that cut bills and automatically reward people for reducing use on the hottest afternoons and coldest mornings.

More than that, the state has got to do more to reward solar customers who generate electricity and return it to the grid when demand rises. These virtual power plants will increasingly provide vital power when the state badly needs it, and consumers need to be rewarded for it. (Fortunately, the state is looking at strategies to take better advantage of virtual power plants.)

Finally, if Texas is helping big generators build gas plants, it should figure out ways to help regular Texans install solar panels and battery storage units. Such systems obviously help protect Texans from power outages, but they also fortify the ERCOT grid by reducing the demand on it.

Last month’s derecho was exactly the sort of freak occurrence that will become more common as the weather grows more extreme. The best way to protect the grid from such catastrophes is to protect individual Texas customers as well.

Report: Solar tops coal in Texas for energy generation for the first time

by the numbers

For the first time in Texas, according to a recent report, solar energy generation surpassed the output by coal.

The report — from the Institute For Energy Economics and Financial Analysis — sourced the Energy Information Administration’s hourly grid monitor for March 2024. This shift in a predominantly oil and gas dominated history of Texas energy output, was due to solar power’s 3.26 million megawatt-hours to Electric Reliability Council of Texas (ERCOT) grid, compared to coal’s 2.96 million MWh.

In addition, coal’s market share fell below 10 percent to 9 percent for the first time ever, to just over 9 percent. The increase in solar energy pushed solar’s share of ERCOT generation to more than 10 percent for the month, which was also a first.

Due to its sheer size, Texas is the No.1 state for solar capacity. According to the report from SmartAsset, the Lone Star State has the most clean energy capacity at 56,405 megawatts, but continues to trail states with similar geographic characteristics in overall clean energy prevalence.

Texas only 38 percent of the state’s electricity capacity comes from clean electricity, and it has the second-largest solar capacity, which means Texas has the most means, space, and potential to accommodate cleaner electricity. Texas as a whole, ranked No. 22 on the list for states with the most clean energy in the SmartAsset report.

In Texas, generation in March 2024 was 1.17 million MWh more year-over-year, which is a 56 percent increase. ERCOT data shows that the system currently has 22,710 megawatts (MW) of operational solar capacity according to IEEFA, and is expected to expand by almost one-third by the end of 2024 with an additional 7,168 MW of capacity added. The number just considers Texas solar projects that have set aside the financing required to get onto the ERCOT grid and that have a signed interconnection agreement.

Texas burned 50.7 million tons of coal for electricity, which was 13 percent of the U.S. total in 2023 according to the EIA grid monitor. Coal's annual share of ERCOT demand ranged from 36 percent to 40 percent from 2003 through 2014. The last year percent. In 2020, coal was under 20 percent in 2020; and was less than 15 percent in 2023 supplying just 13.9 percent of the system’s total demand.

The IEEFA notes coal’s low March production is important because in recent years it has been the moderate temperatures of April and May and steady winds that have affected the usage and the market share.

Houston energy expert looks ahead to climate tech trends of 2026

Guest Column

There is no sugar‑coating it: 2025 was a rough year for many climate tech founders. Headlines focused on policy rollbacks and IRA uncertainty, while total climate tech venture and growth investment only inched up to about 40.5 billion dollars, an 8% rise that felt more like stabilization than the 2021–2022 boom. Deal count actually fell 18% and investor participation dropped 19%, with especially steep pullbacks in carbon and transportation, as capital concentrated in fewer, larger, “safer” bets. Growth-stage funding jumped 78% while early-stage seed rounds dropped 20%.

On top of that, tariff battles and shifting trade rules added real supply‑chain friction. In the first half of 2025, solar and wind were still 91% of new U.S. capacity additions, but interconnection delays, equipment uncertainty, and changing incentive structures meant many projects stalled or were repriced mid‑stream. Founders who had raised on 2021‑style valuations and policy optimism suddenly found themselves stuck in limbo, extending runway or shutting down.

The bright spots were teams positioned at the intersection of climate and the AI power surge. Power demand from data centers is now a primary driver of new climate‑aligned offtake, pulling capital toward firm, 24/7 resources. Geothermal developers like Fervo Energy, Sage Geosystems and XGS did well. Google’s enhanced‑geothermal deal in Nevada scales from a 3.5 MW pilot to about 115 MW under a clean transition tariff, nearly 30× growth in geothermal capacity enabled by a single corporate buyer. Meta and others are exploring similar pathways to secure round‑the‑clock low‑carbon power for hyperscale loads.

Beyond geothermal, nuclear is clearly back on the strategic menu. In 2024, Google announced the first U.S. corporate nuclear offtake, committing to purchase 500 MW from Kairos Power’s SMR fleet by 2035, a signal that big tech is willing to underwrite new firm‑power technologies when the decarbonization and reliability story is compelling. Meta just locked in 6.6GW of nuclear capacity through deals with Vistra, Oklo, and TerraPower.

Growth investors and corporates are increasingly clustering around platforms that can monetize long‑duration PPAs into data‑center demand rather than purely policy‑driven arbitrage.

Looking into 2026, the same trends will continue:

Solar and wind

Even with policy headwinds, solar and wind continue to dominate new capacity. In the first half of 2025 they made up about 90% of new U.S. electricity capacity. Over the 2025–2028 period, FERC’s ‘high‑probability’ pipeline points to on the order of 90–93 GW of new utility‑scale solar and roughly 20–23 GW of new wind, far outpacing other resources.

Storage and flexibility

Solar plus batteries is now the default build—solar and storage together account for about 81% of expected 2025 U.S. capacity additions, with storage deployments scaling alongside renewables to keep grids flexible. Thermal storage and other grid‑edge flexibility solutions are also attracting growing attention as ways to smooth volatile load.

EVs and transport

EV uptake continues to anchor long‑term battery demand; while transportation funding cooled in 2025, EV sales and charging build‑out are still major components of clean‑energy demand‑side investment

Buildings

Heat pumps, smart HVAC, and efficient water heating are now the dominant vectors for building‑sector decarbonization. Heating and cooling startups alone have raised billions since 2020, with nearly 700 million dollars going into HVAC‑focused companies in 2024, and that momentum carried into 2025.

Hydrogen

The green hydrogen narrative has faded, but analysts still see hydrogen as essential for steel, chemicals, and other hard‑to‑abate sectors, with large‑scale projects and offtake frameworks under development rather than headline hype.

CCS/CCUS

After years of skepticism, more large CCS projects are finally reaching FID and coming online, helped by a mix of tax credits and industrial demand, which makes CCS look more investable than it did in the pre‑IRA era.

So, yes, 2025 was a downer from the easy‑money, policy‑euphoria years. But the signal beneath the noise is clear: capital is rotating toward technologies with proven unit economics, real offtake (especially from AI‑driven power loads), and credible paths to scale—not away from climate altogether.

Houston startup advances methane tech, sets sights on growth capital

making milestones

Houston-based climatech startup Aquanta Vision achieved key milestones in 2025 for its enhanced methane-detection app and has its focus set on future funding.

Among the achievements was the completion of the National Science Foundation’s Advanced Sensing and Computation for Environmental Decision-making (ASCEND) Engine. The program, based in Colorado and Wyoming, awarded a total of $3 million in grants to support the commercialization of projects that tackle critical resilience challenges, such as water security, wildfire prediction and response, and methane emissions.

Aquanta Vision’s funding went toward commercializing its NETxTEN app, which automates leak detection to improve accuracy, speed and safety. The company estimates that methane leaks cost the U.S. energy industry billions of dollars each year, with 60 percent of leaks going undetected. Additionally, methane leaks account for around 10 percent of natural gas's contribution to climate change, according to MIT’s climate portal.

Throughout the months-long ASCEND program, Aquanta Vision moved from the final stages of testing into full commercial deployment of NETxTEN. The app can instantly identify leaks via its physics-based algorithms and raw video output of optical gas imaging cameras. It does not require companies to purchase new hardware, requires no human intervention and is universally compatible with all optical gas imaging (OGI) cameras. During over 12,000 test runs, 100 percent of leaks were detected by NETxTEN’s system, according to the company.

The app is geared toward end-users in the oil and gas industry who use OGI cameras to perform regular leak detection inspections and emissions monitoring. Aquanta Vision is in the process of acquiring new clients for the app and plans to scale commercialization between now and 2028, Babur Ozden, the company’s founder and CEO, tells Energy Capital.

“In the next 16 months, (our goal is to) gain a number of key customers as major accounts and OEM partners as distribution channels, establish benefits and stickiness of our product and generate growing, recurring revenues for ourselves and our partners,” he says.

The company also received an investment for an undisclosed amount from Marathon Petroleum Corp. late last year. The funding complemented follow-on investments from Ecosphere Ventures and Odyssey Energy Advisors.

Ozden says the funds will go toward the extension of its runway through the end of 2026. It will also help Aquanta Vision grow its team.

Ozden and Marcus Martinez, a product systems engineer, founded Aquanta Vision in 2023 and have been running it as a two-person operation. The company brought on four interns last year, but is looking to add more staff.

Ozden says the company also plans to raise a seed round in 2027 “to catapult us to a rapid growth phase in 2028-29.”

HETI discusses Houston’s energy leadership, from pathways to progress

The View From HETI

In 2024, RMI in collaboration with Mission Possible Partnership (MPP) and the Houston Energy Transition Initiative (HETI) mapped out ambitious scenarios for the region’s decarbonization journey. The report showed that with the right investments and technologies, Houston could achieve meaningful emissions reductions while continuing to power the world. That analysis painted a picture of what could be possible by 2030 and 2050.

Today, the latest HETI progress report shows Houston is not just planning anymore — the region is delivering.

Real results, right now

The numbers tell a compelling story. Since 2017, HETI’s member companies have invested more than $95 billion in low-carbon infrastructure, technologies, and R&D. That’s not a commitment for the future—that’s capital deployed, projects built, and operations transformed.

The results showed industry-wide reductions of 20% in total Scope 1 greenhouse gas emissions and a remarkable 55% decrease in methane emissions from global operations. These aren’t projections—they’re actual reductions happening across refineries, chemical plants, and production facilities throughout the Houston region.

How Houston is leading

What makes Houston’s approach work is its practical, technology-driven focus. Companies across the energy value chain are implementing solutions that work today:

  • Electrifying operations and integrating renewable power
  • Deploying advanced methane detection and elimination technologies
  • Upgrading equipment for greater efficiency
  • Capturing and storing carbon at commercial scale
  • Developing breakthrough technologies from geothermal to advanced nuclear

Take ExxonMobil’s Permian Basin electrification, Shell and Chevron’s lower-carbon Whale project, or BP’s massive Tangguh carbon capture project in Indonesia. These aren’t pilot programs—they’re multi-billion dollar investments demonstrating that decarbonization and energy production go hand in hand.

From scenarios to strategy

The RMI analysis identified three key pathways forward: enabling operational decarbonization, accelerating low-carbon technology scale-up, and creating carbon accounting mechanisms. Houston’s energy leaders have embraced all three.

The momentum is undeniable. Companies are setting ambitious 2030 and 2050 targets with clear roadmaps. New projects are reaching final investment decisions. Innovation ecosystems are flourishing. And critically, this progress is creating jobs and driving economic growth across the region.

Why this matters

Houston isn’t just managing the energy transition—it’s proving what’s possible when you combine world-class engineering expertise, integrated infrastructure, access to capital, and a commitment to both energy security and emissions reduction.

The dual challenge of delivering more energy with less emissions isn’t theoretical in Houston—it’s operational reality. Every ton of CO₂ reduced, every efficiency gain achieved, and every technology deployed demonstrates that we can meet growing global energy demand while making measurable progress on climate goals.

The path forward

The journey from last year’s scenarios to this year’s results shows something crucial: when industry, policymakers, and communities align around practical solutions, transformation accelerates.

Houston’s energy leadership isn’t about choosing between reliable energy and environmental progress, it’s about delivering both. And based on the progress we’re seeing, the momentum is only building.
