Caterpillar turned the heads of CES attendees with a monstrous, all-electric underground mining loader – but the real game-changer wasn’t the big mining rig, or even the electric excavator. Instead, it was Cat’s cutting-edge energy management systems to keep electric equipment charged up and ready to work.
“We are thrilled to return to CES to showcase our advancements in energy solutions. This event is renowned as the proving ground for breakthrough technologies and global innovators, making it the ideal place for us to demonstrate our leadership in power systems and integrated service solutions, which help our customers in the energy transition,” said Rod Shurman, senior vice president of Caterpillar’s Electrification + Energy Solutions Division.
To that end, Caterpillar showcased a number of on-site generators capable of generating electric power to store in its battery energy storage system (BESS). Caterpillar says its BESS is designed for rapid plug-and-play installation and integration, compatible with any combination of diesel, natural gas, or renewable energy sources.
Granted, fuel-agnostic energy storage is something most BESS products are capable of – but the concept of using on-site batteries for EV charging is still new enough that it might still be news to Cat’s customers. In fairness, Cat’s big BESS offers a comprehensive array of charging ports, making it compatible with almost any EV, charging it in about 20-40 minutes.

Caterpillar also showcased several smaller DC chargers designed to be compact enough for a single worker to wheel up to a piece of electric equipment and charge it with electrons in about three hours.
Speaking of electric equipment, Caterpillar also brought out an electric drive mini excavator fitted with a jackhammer implement meant to show fleet buyers that their legacy Cat accessories would still work once they made the transition to electric – but note: Cat’s excavator isn’t fully electric.

Unlike the fully-electric equipment concepts shown by Doosan Bobcat and HD Hyundai, which use electric actuators and gears to move their boom arms, the Cat 301.9 uses an electric motor to power its wheels and accessories, but still relies on conventional hydraulic oils to manipulate its arm – and that can be a problem in cold climates.
“The electric motors don’t make as much heat as the diesels,” explained “Greg,” one the Caterpillar SMEs on the ground at CES2024. “So it can take a long time to warm up the hydraulics.”
This might seem like a rookie mistake, but Greg clarified, “These are still really new. The first two or three I drove were converted diesel units. This is one of the first ones that was built electric from the start.”
To Caterpillar’s credit, sticking to hydraulic operation will make it easier for operators familiar with Cats to switch to electric. The fact that the hydraulic accessories fleet operators already own will work with the new electric 301.9 also helps lower the EV’s barrier to entry.
The 301.9 mini excavator was displayed alongside its 48 volt on-board battery pack, which offers a total capacity of 32 kWh and delivers 3 hours’ of continuous runtime – which is just enough to handle a full working shift above ground.
Below ground, you’ll want something a little bigger.

The crown jewel of Caterpillar’s CES exhibit this year was the massive Cat R1700 XE LHD underground loader. The R1700 XE LHD offers a whopping 16.5-ton payload and a top speed just over 11 mph – a nightmare-fast speed in the tight confines of a dark underground mine, the loader’s natural habitat.
The good news is that you won’t have your lungs getting choked out by diesel fumes while you try to escape from the big Cat, because this is the only underground loader in the industry powered by onboard battery that can charge in less than 20 minutes when it’s hooked up to two of the big Cat MEC500 chargers we talked about at the beginning of this article.
This is the first of this type of Cat battery packs, which the company claims are a modular design that will power future electric equipment models, as well as with factory integrated telematics and a structure durable to endure the challenges of the job site.
Electrek’s Take
Caterpillar isn’t the only heavy equipment OEM hard at work developing a total job site solution to keep its new EVs charged up – but it did a fantastic job convincing people at CES that they were, and I wanted one of the bright blue CAT trucker caps badly enough not to say anything about it to their face.
That said, I got the chance to have Volvo Penta’s Darren Tasker as a guest on The Heavy Equipment Podcast to talk about Volvo Penta’s efforts to bring more sustainable, lower emission energy to remote job sites. Trust that other companies in the space, surely, are doing the same.

Solar is taking off across Africa in a big way. According to a new analysis of China’s solar panel exports data from energy think tank Ember, solar panel imports into the continent jumped 60% in the 12 months through June 2025, setting a record that could reshape electricity systems in many countries.
In that period, Africa imported 15,032 megawatts (MW) of solar panels, up from 9,379 MW the year before. While South Africa has dominated past surges, this wave is happening across the map: 20 countries set new import records, and 25 countries each brought in at least 100 MW, compared to just 15 a year earlier.
Nigeria overtook Egypt to become the second-largest importer with 1,721 MW, while Algeria surged into third with 1,199 MW. Growth rates in some countries were staggering: Algeria’s imports jumped 33-fold, Zambia’s eightfold, Botswana’s sevenfold, and Sudan’s sixfold. Liberia, the DRC, Benin, Angola, and Ethiopia all more than tripled their imports.
Still, import numbers don’t tell the whole story. It’s unclear how many of these panels have been installed yet. Muhammad Mustafa Amjad of Renewables First, an energy transition think tank in Pakistan, pointed out that countries risk losing valuable time and opportunities without proper tracking. “Africa’s transition will happen regardless,” he said, “but with timely data it can be more equitable, planned, and inclusive.”

If these panels do get installed, the impact could be massive. In Sierra Leone, the past year’s imports alone could cover 61% of the country’s 2023 electricity generation. For Chad, it’s 49%. Liberia, Somalia, Eritrea, Togo, and Benin could all boost generation by more than 10% compared to 2023, and 16 countries could see increases of over 5%.
The economic case is also strong. In Nigeria, solar savings from replacing diesel could repay panel costs in just six months, or even less in other countries. In fact, in nine of Africa’s top 10 solar panel importers, the value of imported refined petroleum outweighed solar imports by factors of between 30 to 107.
Ember’s chief analyst, Dave Jones, called the surge “a pivotal moment,” urging more research and reporting to keep pace with the rapid rise to “ensure the world’s cheapest electricity source fulfills its vast potential to transform the African continent.”

Hyundai and Kia vehicles are popping up on US roads more than ever, and a lot of it has to do with EVs. The South Korean auto giants just hit another milestone as they gear up to introduce several new models.
Hyundai and Kia bet on EVs, hybrids for growth in the US
After launching their first hybrid vehicles in the US in 2011, the Sonata and K5, Hyundai and Kia have come a long way.
Today, two out of ten Hyundai or Kia models sold in the US are considered “eco-friendly,” including electric (EV), hybrid, plug-in hybrid (PHEV), and fuel cell electric (FCEV) vehicles.
After 14 years, Hyundai and Kia announced on Monday that combined, they have now sold over 1.5 million eco-friendly cars in the US. In a statement, the company said it continues seeing strong demand for several models, including the Tucson Hybrid, IONIQ 5, and Niro Hybrid.

Since reaching 100,000 in annual sales in 2021, brand sales of eco-friendly cars have grown rapidly. Hyundai and Kia sold 182,627 units in 2022, 278,122 units in 2023, and 364,441 units in 2024. This year, they sold over 221,500 in the first six months, up 20% from the same period in 2024.
Hybrids accounted for over 1.1 million, followed by electric vehicles with nearly 375,000, and FCEVs at just over 1,850 units sold.

The Hyundai Tucson Hybrid and Kia Niro Hybrid are the brand’s top-selling eco-friendly cars in the US. Hyundai’s Sonata Hybrid and IONIQ 5 ranked second and fourth. Meanwhile, the Kia Sportage Hybrid and Sorento Hybrid placed third and fifth.
Hyundai and Kia offer 19 eco-friendly vehicles in the US, including eight hybrid and PHEVs, 10 EVs, and just one FCEV.

Both brands sold more vehicles in the US in the first half of the year than ever. With Hyundai now building vehicles at its new EV plant in Georgia, including the 2025 IONIQ 5 and 2026 IONIQ 9, the automaker expects the growth to continue. Kia assembles the EV6 and EV9 at a separate plant in Georgia, and will introduce the EV4, its first electric sedan, in early 2026.
Based on the advanced E-GMP platform, Hyundai and Kia’s electric vehicles offer some of the longest driving ranges, fastest charging speeds, and remain surprisingly affordable.

With leases starting as low as $159 per month, the 2025 Hyundai IONIQ 5 is one of the most affordable EV lease deals in the US. Even the three-row IONIQ 9 is listed with monthly leases as low as $299. That’s pretty cheap for a nearly $60,000 three-row electric SUV.
Hyundai will continue to offer hybrids in response to the changing policies under the Trump Administration. It also plans to add hybrid production in Georgia, starting next year.

Three years after the Inflation Reduction Act (IRA) became law, Rewiring America is rolling out a new effort to make sure homeowners don’t miss out on major savings.
The Save on Better Appliances campaign is designed to help families take advantage of federal energy tax credits before they expire at the end of 2025, while also showing how modern electric appliances can cut long-term energy costs.
With utility bills climbing, the group is highlighting the benefits of heat pumps, heat pump water heaters, rooftop solar, and other upgrades that can keep homes comfortable while protecting against future price spikes. For many households, energy-efficient appliances are one of the few ways to bring bills under control – and that value remains even after federal incentives are gone.
Right now, homeowners can still access the federal Energy Efficient Home Improvement Credit (25C) and Residential Clean Energy Credit (25D). On top of that, thousands of state, local, and utility-level incentives are available to help offset upfront costs.

Ari Matusiak, CEO of Rewiring America, pointed out that the IRA incentives were never meant to last forever:
Congress’s decision to repeal them prematurely means households should act fast. But the savings, comfort, and long-term value of these upgrades remain. For homeowners ready to act, we have the tools to help. And for those who need more time, we’re working to expand your options and ensure that these upgrades make financial sense whenever the moment is right.
What the campaign offers
The Save on Better Appliances campaign runs through October and includes:
A central hub where homeowners can learn about the expiring credits, check out state, local, and utility incentives, and connect with vetted contractors.
Weekly Zoom drop-in sessions with Certified Electric Coaches, starting September 3, to answer questions about home upgrades.
Contractor tools, including Rewiring America’s Contractor Finder, soon to be integrated with the BetterHVAC directory for more trusted installer options.
A new Single-Project Personal Electrification Planner to help homeowners map out common projects like heat pumps, energy audits, and electrical upgrades.
“I’ve been doing HVAC installations for the past 40 years, and I can tell you that I’ve seen firsthand how the 25C tax credit has made heat pumps, the most efficient HVAC technology, more affordable and accessible for homeowners,” said Scotty Libby, owner of Maine-based Royal River Heat Pumps. “Homeowners should talk to their local contractors now if they want to upgrade their HVAC, take advantage of the tax credit, and lock in the potential long-term energy savings a heat pump would provide.”
Beyond tax credits
Rewiring America is also working with manufacturers, contractors, and lenders to make upgrades more affordable, even without federal help. In Rhode Island and Colorado, families can already access specially priced heat pump packages, with more states on the way. These deals will expand in 2026 and beyond, lowering upfront costs no matter what happens in Washington.
Across the country, state agencies, utilities, and local nonprofits are already leading creative programs to help families save money, find trusted contractors, and begin electrifying their homes. Rewiring America says this campaign is about amplifying that work and making it easier for households to take the first step.
“Tax credits may expire, but the benefits of better HVAC – lower bills, healthier homes, and lasting comfort – are here to stay. That’s why we’re supporting Rewiring America’s campaign,” said Bill Spohn, Sr., president of the Better HVAC Alliance.
