4 Houston energy companies named best places to work by U.S. News

Where to Work

Nearly a dozen public and private Houston-based companies have been hailed among the best places to work in 2025 by U.S. News and World Report, with four from the energy sector.

The annual "U.S. News Best Companies to Work For" report examines thousands of publicly-traded companies around the world to determine the best employers based on six metrics including work-life balance and flexibility; quality of pay and benefits; job and company stability; career opportunities and professional development; and more. The companies were not ranked, but included based on reader surveys and publicly available data about each workplace.

New for the 2025-2026 ratings,U.S. News expanded its methodology to include privately owned companies and companies with internship opportunities for recent graduates and new, current, and prospective students. Companies were also grouped into job-specific and industry-specific lists, and the publication also added a new list highlighting "employers that are particularly friendly to employees who are also caregivers in their personal lives."

U.S. News included seven publicly-traded companies and four privately owned companies in Houston on the lists.

Houston-based energy companies on the list

It may not come as a surprise that oil and gas corporation Chevron landed at the top of the list of top public employers in the Energy Capital of the World. The energy giant currently employs more than 45,000 people, earns $193.47 billion in annual revenue, and has a market cap of $238.74 billion. The company earned high ratings by U.S. News for its job stability, "belongingness," and quality of pay.

Chevron also appeared in U.S. News'industry-specific "Best in Energy and Resources" list, the "Best Companies in the South" list, and the "Best for Internships" list.

Chevron is joined by three other Houston energy leaders:

Calpine – Best in Energy and Resources; Best Companies (overall)
ConocoPhillips – Best in Energy and Resources; Best Companies (overall); Best in Caregiving; Best Companies in the South
Occidental – Best in Energy and Resources; Best Companies (overall); Best Companies in the South

Other top companies to work for in Houston are:

American Bureau of Shipping (ABS) — Best in Engineering and Construction; Best Companies (overall)
Hines – Best in Real Estate and Facilities Management; Best Companies (overall)
Insperity, Kingwood – Best in Healthcare and Research; Best Companies (overall); Best in Caregiving; Best Companies in the South
KBR – Best in Engineering and Construction; Best Companies (overall); Best Companies in the South
Men's Warehouse – Best in Consumer Products; Best Companies (overall)
PROS – Best in Information Technology; Best Companies (overall); Best Companies in the South
Skyward Specialty Insurance – Best in Finance and Insurance; Best Companies (overall); Best Companies in the South

"'Best' is a subjective term relative to career satisfaction, and many aspects factor into someone’s decision to apply for a job with any given company," U.S. News said. "But some universally desired factors can contribute to a good workplace, such as quality pay, good work-life balance, and opportunities for professional development and advancement

In all, 30 employers headquartered in the Lone Star State made it onto U.S. News' 2025-2026 "Best Places to Work For" lists. Houston and the Dallas-Fort Worth metro area tied for the most employers make the list, at 11 companies each. Diamondback Energy in Midland was the only company from West Texas to make it on the list for the second year in a row.

Texas plugs in among states at highest risk for summer power outages in 2025

by the numbers

Warning: Houston could be in for an especially uncomfortable summer.

A new study from solar energy company Wolf River Electric puts Texas at No. 2 among the states most at risk for power outages this summer. Michigan tops the list.

Wolf River Electric analyzed the number of large-scale outages that left more than 5,000 utility customers, including homes, stores and schools, without summertime electricity from 2019 to 2023. During that period, Texas experienced 7,164 summertime power outages.

Despite Michigan being hit with more summertime outages, Texas led the list of states with the most hours of summertime power outages — an annual average of 35,440. That works out to 1,477 days. “This means power cuts in Texas tend to last longer, making summer especially tough for residents and businesses,” the study says.

The Electric Reliability Council of Texas (ERCOT), which operates the electric grid serving 90 percent of the state, predicts its system will set a monthly record for peak demand this August — 85,759 megawatts. That would exceed the current record of 85,508 megawatts, dating back to August 2023.

In 2025, natural gas will account for 37.7 percent of ERCOT’s summertime power-generating capacity, followed by wind (22.9 percent) and solar (19 percent), according to an ERCOT fact sheet.

This year, ERCOT expects four months to surpass peak demand of 80,000 megawatts:

June 2025 — 82,243 megawatts
July 2025 — 84,103 megawatts
August 2025 — 85,759 megawatts
September 2025 — 80,773 megawatts

One megawatt is enough power to serve about 250 residential customers amid peak demand, according to ERCOT. Using that figure, the projected peak of 85,759 megawatts in August would supply enough power to serve more than 21.4 million residential customers in Texas.

Data centers, artificial intelligence and population growth are driving up power demand in Texas, straining the ERCOT grid. In January, ERCOT laid out a nearly $33 billion plan to boost power transmission capabilities in its service area.

Texas cities swelter with 50+ more hot days, new climate study shows

summer temps

Mother Nature is cranking up the summertime heat in Texas.

New data from Climate Central shows Houston and Austin are among nine major U.S. cities that now experience at least 50 more days per year with above-normal summer temperatures than they did in 1970. Other Texas cities that made the list were El Paso, McAllen and Tyler. Climate Central is a nonprofit organization that provides climate science research and analysis.

“Climate change is driving increasing temperatures across Texas and causing hotter summers. Austin and Houston now experience at least 50 more days above normal than they did in 1970,” said Kristina Dahl, vice president of science at Climate Central. “This isn’t just about discomfort; it’s about the growing risks to public health and infrastructure. We must prioritize climate resilience and stop burning fossil fuels to address these escalating challenges.”

For Austin, the number of above-normal-temperature summer days climbed by 50 from 1970 to 2024, according to Climate Central. During that period, the average summer temperature in Austin increased by 4.7 degrees.

In Houston, the quarter-century increase in the number of above-normal-temperature summer days was even higher — 56. The average summer temperature there rose by 4.6 degrees from 1970 to 2024, according to Climate Central.

Climate Central says that of the 242 cities it analyzed, 97 percent had seen a rise in the number of hotter-than-normal summer days (June, July and August) between 1970 and 2024. The study found the average jump in summer temperatures since 1970 was 2.6 degrees.

Outside Texas, cities on the list were Reno, Nevada; Albany, Georgia; Las Cruces, New Mexico; and New Orleans.

In the summer, the cities that warmed up the most from 1970 to 2024 were:

Reno, up 11.3 degrees.
Boise, Idaho, up 6.3 degrees.
El Paso, up 6.2 degrees.
Las Vegas, up 6.1 degrees.
Salt Lake City, up 5.9 degrees.

“As heat-trapping pollution continues to warm the planet,” Climate Central explains, “summer temperatures are arriving earlier and getting hotter — and dangerous heat extremes are becoming more frequent and intense.”

Climate Central’s study was based on weather data from the National Oceanic and Atmospheric Administration (NOAA).
