Texas among top states for EV charging access, report shows

by the numbers

A new study from FinanceBuzz reports that Texas has the fifth most public electric vehicle charging stations among states in the U.S.

In its Electric Vehicle (EV) Statistics [2025]: Trends in Sales, Savings, and More report, FinanceBuzz, a personal finance and investment adviser, compiled electric vehicle data to find sales trends, adoption rates, charging infrastructure, costs, savings and more.

Texas has a total of 3,709 public EV charging stations, which equals about 16 stations per 1,000 EVs, according to the report. The remaining top five included:

  • No. 1 California with 17,122 EV charging stations
  • No. 2 New York with 4,814 EV charging stations
  • No.3 Massachusetts with 3,738 EV charging stations
  • No. 4 Florida with 3,715 EV charging stations

Los Angeles had the most public charging stations at 1,609 among U.S. cities. Austin was Texas’s top city with 656 stations.

The study also looked at how much Americans are spending on transportation, and found that the average American using a gas vehicle spends $1,865 annually on fuel. FinanceBuzz found that electric vehicle owners would pay 65 percent less on energy costs. Calculations were based on driving 14,489 miles annually, which measures to 37.9 miles per day. The full report sourced data from the International Energy Agency, the U.S. Department of Energy, the U.S. Department of Transportation, AAA, the U.S. Energy Information Administration and other organizations.

The report said Americans purchased over 1.5 million EVs in 2024, which equals approximately 10 percent of all new light-duty vehicles sold, citing information from the International Council on Clean Transportation.

While Tesla remains the most popular make, 24 new EV models were launched in 2024 by other companies, which represents a 15 percent increase from the previous year.

Other trends in the report included:

  • The U.S. now has more than 64,000 public charging stations and over 168,000 charging ports, which is up from fewer than 1,000 stations in 2010.
  • An average EV owner will spend about $654 per year on electricity, compared to $1,865 for a gas-powered vehicle. The savings equate to about $1,211 per year.
  • In 2024, U.S. EV sales surpassed 1.5 million, but the pace slowed compared to the previous year, with a 10 percent increase versus 40 percent in 2023.
  • Insuring an EV can be more costly because parts are harder to come by, making repairs and replacements more expensive.
  • In the second quarter of 2024, nearly half of new EVs were leased, which is a 28 percentage point increase since 2021.

Houston team’s discovery brings solid-state batteries closer to EV use

a better battery

A team of researchers from the University of Houston, Rice University and Brown University has uncovered new findings that could extend battery life and potentially change the electric vehicle landscape.

The team, led by Yan Yao, the Hugh Roy and Lillie Cranz Cullen Distinguished Professor of Electrical and Computer Engineering at UH, recently published its findings in the journal Nature Communications.

The work deployed a powerful, high-resolution imaging technique known as operando scanning electron microscopy to better understand why solid-state batteries break down and what could be done to slow the process.

“This research solves a long-standing mystery about why solid-state batteries sometimes fail,” Yao, corresponding author of the study, said in a news release. “This discovery allows solid-state batteries to operate under lower pressure, which can reduce the need for bulky external casing and improve overall safety.”

A solid-state battery replaces liquid electrolytes found in conventional lithium-ion cells with a solid separator, according to Car and Driver. They also boast faster recharging capabilities, better safety and higher energy density.

However, when it comes to EVs, solid-state batteries are not ideal since they require high external stack pressure to stay intact while operating.

Yao’s team learned that tiny empty spaces, or voids, form within the solid-state batteries and merge into a large gap, which causes them to fail. The team found that adding small amounts of alloying elements, like magnesium, can help close the voids and help the battery continue to function. The team captured it in real-time with high-resolution videos that showed what happens inside a battery while it’s working under a scanning electron microscope.

“By carefully adjusting the battery’s chemistry, we can significantly lower the pressure needed to keep it stable,” Lihong Zhao, the first author of this work, a former postdoctoral researcher in Yao’s lab and now an assistant professor of electrical and computer engineering at UH, said in the release. “This breakthrough brings solid-state batteries much closer to being ready for real-world EV applications.”

The team says it plans to build on the alloy concept and explore other metals that could improve battery performance in the future.

“It’s about making future energy storage more reliable for everyone,” Zhao added.

The research was supported by the U.S. Department of Energy’s Battery 500 Consortium under the Vehicle Technologies Program. Other contributors were Min Feng from Brown; Chaoshan Wu, Liqun Guo, Zhaoyang Chen, Samprash Risal and Zheng Fan from UH; and Qing Ai and Jun Lou from Rice.

Houston company to develop game-changing lithium-sulfur EV batteries for automaker

team work

Houston-based Zeta Energy Corp. has teamed up with an automaker to develop new battery technology.

Zeta Energy and Stellantis N.V. announced a joint development deal to advance battery cell technology for electric vehicle applications that will develop lithium-sulfur EV batteries with gravimetric energy density that can achieve a volumetric energy density comparable to today’s lithium-ion technology. The batteries are targeted to power Stellantis electric vehicles by 2030.

“The combination of Zeta Energy’s lithium-sulfur battery technology with Stellantis’ unrivaled expertise in innovation, global manufacturing and distribution can dramatically improve the performance and cost profile of electric vehicles while increasing the supply chain resiliency for batteries and EVs,” Tom Pilette, CEO of Zeta Energy, says in a news release.

The batteries will be produced using waste materials and methane that boasts lower CO2 emissions than any existing battery technology. Zeta Energy battery technology is intended to be manufacturable within existing gigafactory technology and would leverage an entire domestic supply chain in Europe or North America.

The technology can lead to a significantly lighter battery pack with the same usable energy as contemporary lithium-ion batteries. The companies believe this will enable greater range, improved handling and enhanced performance. The technology has the potential to improve fast-charging speed by up to 50 percent, which can make EV ownership easier.

Lithium-sulfur batteries are expected to cost less than half the price per kilowatt of current lithium-ion batteries according to a news release. Zeta has more than 60 patents on its proprietary lithium-sulfur anode and cathode technologies.

Lighter and more compact EV batteries have become an important design goal for vehicle designers and manufacturers. This objective is similar to what General Motors is doing with prismatic cell technology with LG Energy Solution.

“Our collaboration with Zeta Energy is another step in helping advance our electrification strategy as we work to deliver clean, safe and affordable vehicles,” Ned Curic, Stellantis chief engineering and technology officer, says in the release. “Groundbreaking battery technologies like lithium-sulfur can support Stellantis’ commitment to carbon neutrality by 2038 while ensuring our customers enjoy optimal range, performance and affordability.”

Last year, Zeta Energy announced that it was selected to receive $4 million in federal funding for the development of efficient electric vehicle batteries from the U.S. Department of Energy's ARPA-E Electric Vehicles for American Low-Carbon Living, or EVs4ALL, program.

Tesla posts surprise $2.17B third-quarter profit, up from a year ago

by the numbers

Tesla’s third-quarter net income rose 17.3 percent compared with a year ago on stronger electric vehicle sales, and an optimistic CEO Elon Musk predicted 20 percent to 30 percent sales growth next year.

The strong performance changed the trajectory of the year for the Austin, Texas-based company, which had seen sales and profits decline in the first two quarters.

In its letter to investors, Tesla predicted slight growth in vehicle deliveries this year, better than the 1.8 million delivered worldwide in 2023.

Tesla said Wednesday that it made $2.17 billion from July through September, more than the $1.85 billion profit it posted in the same period of 2023.

The earnings came despite price cuts and low-interest financing that helped boost sales of the company’s aging vehicle lineup during the quarter. It was Tesla’s first year-over-year quarterly profit increase of 2024, a year plagued by falling sales and prices.

Revenue in the quarter rose 7.8 percent to $25.18 billion, falling short of Wall Street analysts who estimated it at $25.47 billion, according to FactSet. Tesla made an adjusted 72 cents per share, soundly beating analyst expectations of 59 cents.

Shares in Tesla Inc. soared nearly 12 percent in trading after Wednesday’s closing bell.

On a conference call with analysts, Musk said the profit increase came despite a challenging environment for auto sales with still-high loan interest rates. “I think if you look at EV companies worldwide, to the best of my knowledge, no EV company is even profitable,” he said.

Musk qualified his prediction that Tesla would post 2025 vehicle sales growth of 20 percent to 30 percent by saying it could be changed by “negative external events.”

Earlier this month Tesla said it sold 462,890 vehicles from July through September, up 6.4 percent from a year ago. The sales numbers were better than analysts had expected.

The letter said that Tesla is on track to start production of new vehicles, including more affordable models, in the first half of next year, something investors had been looking for. The new vehicles will use parts from its current models and will be made on the same assembly lines as Tesla’s current model lineup, the letter said.

The new vehicles were not identified and the price was nebulous. Musk has said in the past the company is working on a car that will cost about $25,000, but said Wednesday that a new affordable vehicle would cost under $30,000 including government tax incentives.

Earlier this month, the company showed off a purpose-built two-seat robotaxi called “Cybercab” at a glitzy event at a Hollywood movie studio. Musk said it would be in production before 2027 and cost around $25,000.

By using parts from existing models and the current manufacturing system, Tesla won’t reach cost reductions that it previously expected using a new manufacturing setup.

Tesla said it reduced the cost of goods per vehicle to its lowest level yet, about $35,100.

The company’s widely watched gross profit margin, the percentage of revenue it gets to keep after expenses, rose to 19.8 percent, the highest in a year, but still smaller than the peak of 29.1 percent in the first quarter of 2022.

During the quarter, Tesla’s revenue from regulatory credits purchased by other automakers who can’t meet government emissions targets hit $739 million, the second highest quarter in company history.

Musk said Tesla's “Full Self-Driving” system is improving and would drive more safely than humans in the second quarter of next year. Despite the name, Teslas using “Full Self-Driving” cannot drive themselves, and human drivers must be ready to intervene at all times.

The company, he said, is offering an autonomous ride-hailing service to employees in the San Francisco Bay Area, but it currently has human safety drivers. It expects to start a robotaxi service for the public in California and Texas next year, he said.

Musk also conceded that it may not be possible to reach autonomous driving safety levels with older editions of “Full Self-Driving” hardware. If it can't do that, Tesla will upgrade computers in the older cars for free, he said.

The self-driving claims come just five days after U.S. safety regulators opened an investigation into the system's cameras to see in low-visibility conditions such as sun glare, fog and airborne dust. The probe raised doubts about whether the system will be ready to drive on its own next year.

The National Highway Traffic Safety Administration said in documents posted Friday that it opened the probe of 2.4 million Teslas after the company reported four crashes in low visibility conditions. In one, a woman who stopped to help after a crash on an Arizona freeway was struck and killed by a Tesla.

Investigators will look into the ability of “Full Self-Driving” to “detect and respond appropriately to reduced roadway visibility conditions."

Edward Jones analyst Jeff Windau said the earnings report and conference call showed that Tesla is making money on software, a business with high profit margins.

Still, he has a “hold” rating on the stock as the company moves toward robotics and autonomous vehicles. “They’ve got a lot of challenging goals out there,” he said.

Texas automaker invests in first-of-its-kind EV charging station initiative

plugging in

A charging network founded by eight of the world’s top automakers have announced that they have broken ground on their first electric vehicle charging station.

IONNA will work to transform a historic district gas station into a new "Rechargery" in North Carolina. The initiative is backed by Plano-based Toyota, along with BMW, General Motors, Honda, Hyundai, Mercedes-Benz, Kia, and Stellantis.

With plans to open locations across the country, the station will provide 10 covered parking bays and will be accessible to both CCS and NAC chargers. The charging ports will be capable of up to 400 kilowatts and 800+ Volts. The site will also include an indoor driver’s lounge, coffee service, food/beverage, restrooms, and WIFI.

“We are excited to announce our support of IONNA to deploy DC fast chargers throughout the U.S. and Canada,” Ted Ogawa, president and CEO of Toyota Motor North America, says in a news release. “We believe this will not only promote the adoption of BEVs and increase customer confidence in the technology, but it will provide our Toyota and Lexus customers with access to IONNA’s rapidly growing charging network in North America.”

IONNA will “enable urban and long-distance EV mobility for all with over 30,000 ultra-fast-and-reliable charging points by 2030” according to the company.

IONNA also announced Jackie Slope as the Chief Technology Officer. Slope previously worked with customer experiences at Crypto.com Arena and Madison Square Garden.

“Having spent my career raising the bar around the customer experience I am excited to find ways to innovate and elevate the charging experience by serving the customer above all else in this new and exciting industry,” Slope said in a news release.

While the North Carolina location is the first of its kind, IONNA plans to expand its Rechargery stations around North America soon.

In other EV news, Hyundai Motor and Kia launched a project on Sept. 25 to develop lithium iron phosphate (LFP) battery cathode material. Hyundai Steel and cathode material market leader EcoPro BM will aim to synthesize materials directly without creating a precursor for LFP battery cathode material production

Houston developer launches AI-powered water platform to boost efficiency

eyes on AI

Houston real estate company McCord Development has launched an artificial-Intelligence-run water management platform, MizuWatch.

MizuWatch aims to help operators, districts, and municipalities detect leaks faster, reduce water loss and improve efficiency, according to the company. MizuWatch pulls data from supply sources, smart meters, historical usage and maintenance records, and combines them into a single platform. The AI system also uses visual mapping and digital twin technology to deliver near-real-time system insights.

“MizuWatch brings the right data together daily, so teams can see what’s happening now, intervene earlier and focus their resources where they have the greatest impact,” Jerzy Wielgus, chief product officer for MizuWatch, said in a news release.

MizuWatch was built to “scale across geographies and system sizes to help assist with water scarcity, aging infrastructure, and operational complexity,” according to the company. It was developed at Houston’s Generation Park, McCord’s 4,300-acre master planned commercial district. McCord was able to pilot the platform onsite to help manage its complex, real-world water systems at scale.

“Resilient infrastructure is a key factor for the companies choosing Generation Park,” Ryan McCord, CEO of McCord Development and Founder & CEO of MizuWatch, added in the release. “We made the decision to deploy smart meters, but no one knew how to use the data they generate. This is an opportunity across all infrastructure where sensors are deployed. What started as an internal solution has become a platform we believe can help stakeholders everywhere be more efficient in their operations, investment, and compliance.”

Last fall, Eli Lilly and Co. selected Generation Park for its $6.5 billion manufacturing plant. More than 300 locations in the U.S. competed for the factory. Bristol Myers Squibb Co., another pharmaceutical giant, also announced it is considering Generation Park for a new manufacturing hub earlier this month.

Oil giant BP ousts new chairman over serious conduct concerns

Sudden Exit

BP has ousted its chairman over what it called serious concerns related to “important governance standards, oversight and conduct.”

The departure was abrupt and unexpected, with Albert Manifold having been appointed to the position late last year.

“Albert has helped bring a welcome focus and pace to BP’s transformation," Amanda Blanc, senior independent director, said in a statement Tuesday, May 26. "However, the board has been surprised and disappointed to learn of governance oversight and conduct issues it deems unacceptable and has taken decisive action.”

BP's board named Ian Tyler as interim chair, effective immediately.

BP, based in London and with North American headquarters in Houston, is a “supermajor,” one of the five largest oil production and exploration companies in the world when measured by revenue and profit.

Manifold, who had been the top executive at Dublin-based global building materials company CRH for 10 years, became the chair at BP in October. BP was looking for someone to revamp the oil giant and went with an industry outsider in Manifold, who had made major strategic changes at CRH.

After a new focus on renewable energy at BP in 2020, by 2025 the company was seeking a return to its roots. BP's hard reset was criticized by environmentalists, as well as some shareholders.

CEO Murray Auchincloss said last year that optimism over opportunities in renewable energy was misplaced, with the company moving “too far and too fast.”

Changes in leadership at BP in recent years has been tumultuous.

CEO Bernard Looney resigned in late 2023 after BP determined that he had misled the company over his past relationships with colleagues.

Auchincloss stepped down in December, and the company named Meg O'Neill as his successor.

Manifold’s was challenged almost immediately when shareholders defeated company resolutions this spring that would have allowed BP to reduce climate reporting requirements and move its annual meetings fully online. Some 18% of shareholders voted against Manifold’s election as chairman, a high level of opposition for an appointment that is generally rubber stamped by investors.

Legal & General, one of Britain’s largest insurers and investment companies, said at the time that Manifold was responsible for resolutions that would have had “a negative impact on shareholders’ insight into how the company is addressing financially material long-term risks, and seizing long-term value creation opportunities, associated with the energy transition,” the Times of London reported on April 23.

Glass Lewis, an influential shareholder advisor, urged investors to vote against Manifold’s election. It held that BP took “unprecedented action” by refusing to consider a resolution from a group of climate activists and pension funds hoping to force the board to create an alternative strategy should demand for fossil fuels decline, the Times reported.

Like other big oil companies, BP has struggled with falling demand in recent years.

BP’s 2025 earnings fell 16% from a year earlier to $7.49 billion as the price of Brent crude, a benchmark for international oil prices, dropped 16.9%. The company’s preferred measure of earnings is underlying replacement cost profit, which adjusts for one-time items and fluctuations in the market value of inventories. Net income plunged 86% to $55 million.

Last year there were media reports that British oil giant Shell was in talks to buy rival BP. Shell denied the reports at the time.

The search for a new chair is underway, BP said Tuesday. Shares of BP Plc slid nearly 5% in midday trading on the NYSE.
