Mike Roeth has clocked thousands of miles pulling his solar-powered recreational vehicle around the country in his quest to make trucking cleaner and more efficient. For some it may seem strange that an effort to curb fuel takes fuel, since Roeth pulls his RV with a diesel-powered Ford F-250.

But for Roeth, executive director of the North American Council for Freight Efficiency (NACFE) and trucking lead for RMI, it makes total sense. Roeth likes to live by the concept of “gemba,” a Japanese word meaning “the actual place.” He learned it in the 1990s while he was managing a plant for a manufacturer of engines and power systems. His plant was implementing a production system similar to Toyota’s, and Roeth was studying the Japanese automaker’s efforts when he discovered gemba.

Gemba means going to see the actual process and learning from those who do the work. Inside a Toyota factory, it means that management walks the floor to observe the manufacturing process up close. In Roeth’s world, it means that he is constantly out on the road, meeting with trucking companies and chatting with truck drivers. His goal is to understand the latest technologies for reducing emissions in a sector that is responsible for 24 percent of transportation’s greenhouse gas footprint.

Roeth grew up on a farm near Dayton, Ohio. He has been around tractors and trucks since he was a toddler. After graduating from Ohio State University with an engineering degree and working with different companies, he eventually became a vice president at Navistar, the company that owns the International brand of trucks and diesel engines. Roeth traveled a lot for work, and when he left Navistar, he decided he wanted to spend more time with his wife, Letty. He told her he would look for a job in Fort Wayne, Indiana, where they were living at the time.

Letty, however, knew her husband better than that. “That’s not you—you have to be traveling and out with people,” she told him. “Why don’t we buy a camper? I’ll go with you and see how we like it.” Roeth became an industry consultant, and they instantly fell in love with working on the road.

Getting the Efficiency Bug

Although Roeth loves working in the trucking industry, he was bothered by the lack of interest in efficiency technologies when fuel prices were low. “I was frustrated to find out that over the past 50 years, when fuel prices went up the industry wanted to lower costs and be more efficient, but when prices went down they didn’t,” he said. As a result, a lot of efficiency technologies were being discarded. “I knew that we need to and can do better with the emissions that move our goods.”

Around the same time that the Roeths were taking to the road, RMI hosted a workshop on efficient trucking with the goal of doubling the efficiency of the trucking sector. NACFE, an independent organization helping to drive efficiency in the trucking sector, was born out of that charrette, and Roeth was the perfect person to take it on.

“The thing I like about trucking is that it’s a small industry: only about half a million trucks are produced in a given year. It forces everyone to work together,” Roeth says. “Even though all the companies have divergent goals, and there’s a very diverse, complex market of trucking, it’s also incredibly collaborative.” That dynamic is ideal for Roeth, who excels at getting people together to work toward a common goal.

“Mike has an incredible resume of experience,” says Amanda Phillips, general manager of OEM (original equipment manufacturer) sales at Meritor, a corporation that makes truck components. “He is always willing to share ideas and teach others. His energy and positive attitude are contagious.” From 2010 to 2016, Roeth nurtured NACFE from a small startup nonprofit to the leading organization on trucking efficiency. According to Phillips, “Mike’s entrepreneurial spirit and his work with NACFE have helped fleets better understand available technologies and the impact those advances can make in their fleet’s carbon footprint.”

During that same time, the Roeths got progressively bigger campers and started being gone more often. They eventually sold their house, got rid of most of their stuff, and became full-time RVers. They now have a 41-foot Jayco Eagle outfitted with a 1.4 kilowatt solar array to run their appliances.

The Roeths’ next step is to replace both their truck and camper with a motor home that pulls an electric car. Then, when parked at a campsite, they can drive their electric car for shorter trips. They hope to eventually get away from fossil fuels completely with an electric or hydrogen-powered truck that can pull an RV.

The Birth of Run on Less

In 2016, the NACFE team was trying to figure out how efficient a tractor trailer could be if it incorporated the best available efficiency technologies. The team thought the best way to do that was to track some of the most fuel-efficient trucks, driven by efficiency-focused drivers. And with that, Run on Less was born.

The first Run on Less event featured seven fleets, outfitted with different fuel-efficiency measures, in a cross-country demonstration. NACFE followed the fleets across the country and proved that fleets can improve their fuel efficiency by 25 percent if they adopt the right technologies.

The event was so successful that NACFE held a second Run on Less event in 2019. This one included 10 fleets, many very large, focused on regional haul. The second demonstration proved that the 800,000 trucks in North America could decrease their annual consumption of diesel from 8 billion gallons to 5.5 billion gallons, and eventually down to 1 billion gallons.

“Run on Less is just a gift that keeps on giving,” says Roeth. “It’s real, it’s human. We talk to truckers and the people buying trucks and running them, and then we share their stories and data. Do we like it because it’s fun or because the marketplace likes it? I think it’s a bit of both.”

To Roeth, the future of trucking looks bright. He’s most excited about electric and hydrogen trucks. “To think we can move freight with no emissions is incredible,” he says. “Trucking has done a lot. Diesel exhaust is cleaner now. I’m really proud of the industry. But it’s still carbon-based. I’m most excited about moving the industry to zero carbon.”

Roeth is getting an up-close glimpse at a carbon-free future for trucking in the third Run on Less demonstration, called Run on Less–Electric. This event, beginning September 2, features 13 electric trucks in a variety of real-world applications for companies including Frito-Lay, Anheuser-Busch, and Penske.

In addition to new technologies, Roeth is also excited about the changes in terms of diversity that he has seen over the 35 years he’s been involved in the industry. “The meetings I was in 30 years ago were all mostly white men. Now we have women and people of color involved from management to drivers,” he explains.

Living the Gemba Way

While many people took to the road during the COVID pandemic, the Roeths actually stayed put. Part of the joy of being on the road for the Roeths is not only attending industry events, but also going to museums, sporting events, and pubs, and meeting interesting people across the country.

Mike Roeth: Decarbonizing Trucking from the RoadWith COVID putting a stop to most of that, they felt they had no reason to go anywhere, so they hunkered down in Indiana. But it wasn’t the same. “During the pandemic I felt I was getting out of touch with trucking,” says Roeth. So he is now back on the road meeting with trucking companies, manufacturers, and drivers.

In the weeks leading up to Run on Less–Electric, he has been traveling around the country visiting most of the 13 companies involved, from Los Angeles to New York City. He has conducted dozens of interviews of fleet managers, company leaders, and truck drivers.

In this way, he learns firsthand about the benefits of electric trucks as well as any challenges the companies have faced. He then uses this knowledge to help increase the use of electric trucks in the industry. After one and a half years of COVID, he is back in his element: observing, listening, learning, and sharing ideas face-to-face. And that’s at the heart of how Roeth tries to live—the gemba way.

As Texas power demand surges, solar, wind and storage carry the load

As Texas power demand surges, solar, wind and storage carry the load

Electricity demand is surging in Texas, and solar, wind, and battery storage are meeting it.

According to new data from the US Energy Information Administration (EIA), electricity demand across the Texas grid managed by the Electric Reliability Council of Texas (ERCOT) hit record highs in the first nine months of 2025. ERCOT, which supplies power to about 90% of the state, saw demand jump 5% year-over-year to 372 terawatt hours (TWh) – a 23% increase since 2021. No other major US grid has grown faster over the past year.

Solar and wind keep ERCOT’s grid steady

The biggest growth story in Texas power generation is solar. Utility-scale solar plants produced 45 TWh from January through September, up 50% from 2024 and nearly four times what they generated in 2021 (11 TWh). Wind power also continued to climb, producing 87 TWh through September – a 4% increase from last year and 36% more than in 2021.

Together, wind and solar supplied 36% of ERCOT’s total electricity over those nine months. Solar, in particular, has transformed Texas’s daytime energy mix. From June to September, ERCOT solar farms generated an average of 24 gigawatts (GW) between noon and 1 pm – double the midday output from 2023. That growth has pushed down natural gas use at midday from 50% of the mix in 2023 to 37% this year.

Battery storage is filling in the gaps

Batteries charge during the day when wind and solar generation are the highest, and they produce electricity when generation from wind and solar slows down. ERCOT began reporting battery output separately in October 2024 in its hourly grid data, and it’s clear that batteries are now helping to smooth out evening peaks. This past summer, batteries supplied an average of 4 GW of power around 8 pm, right as solar production dropped off.

Natural gas is flatlining

Natural gas is still Texas’s dominant power source, but it isn’t growing like it used to. Between January and September, gas-fired plants generated 158 TWh of electricity, compared to 161 TWh in 2023. Gas comprised 43% of ERCOT’s generation mix during the first nine months of 2025, down from 47% in the first nine months of 2023 and 2024.

More demand growth ahead

The EIA expects Texas electricity demand to keep rising faster than any other grid in the US. In its latest Short-Term Energy Outlook, the EIA projects ERCOT’s demand will climb another 14% in the first nine months of 2026, reaching 425 TWh. That means Texas will need even more solar, wind, and battery storage to keep up with its breakneck growth.

Chevy Equinox EV and another Cadillac electric SUV recalled due to tire defect

GM is recalling nearly 23,000 Chevy Equinox EV and Cadillac Optiq models due to a defect where the tire tread could fall off.

GM is recalling more Chevy Equinox EV models

In a letter sent to the National Highway Traffic Safety Administration (NHTSA), GM said it has decided to issue a safety recall for certain Chevy Equinox EV and Cadillac Optiq models from model years 2025 to 2026.

This time, it isn’t necessarily GM’s fault. The vehicles may be equipped with 21″ all-season tires that Continental Tire is recalling.

According to Continental, the tires were produced during the week of October 6, 2024, and may have a defect where the tire tread could partially or fully detach. The records show the defect is due to a nonconforming tread base rubber compound.

On September 18, 2025, GM inspected the assembly plant and confirmed there were no suspect tires in stock. The 21″ tires come standard on RS trims and are optional on LT1 and LT2 grades.

Although GM is recalling 22,914 Chevy Equinox EVs and Cadillac Optiqs, it estimates that only about 1% of them have the defect.

The recall includes:

  • 2026 Cadillac Optiq: 214
  • 2026 Chevy Equinox EV: 1,832
  • 2025 Cadillac Optiq: 3,468
  • 2025 Chevy Equinox EV: 17,400

GM dealers will check all four tires and replace them if needed, free of charge. Dealers were notified on October 16. Owner notification letters are expected to be mailed out on December 1, 2025.

You can contact Chevrolet’s customer service number at 1-800-222-1020 or Cadillac’s at 1-800-333-4223. GM’s recall number is N252525030. Owners can also call the NHTSA hotline at 1-888-327-4236 or visit the nhtsa.gov website for more information.

The Chevy Equinox EV is now the third best-selling EV in the US, trailing only the Tesla Model Y and Model 3. Meanwhile, Cadillac’s entry-level Optiq SUV is the fifth-most-popular luxury EV. The recall is minor and only affects a small percentage of models, so it’s not expected to have a major impact.
