The energy demand for data centers is surging right along with record-setting heat domes and conversations about a new “Category 6” for hurricanes, bringing serious concerns about grid stability on summer’s hottest days. That’s the kind of problem that keeps the heating and cooling specialists at Carrier awake at night, but they’ve come up with a scalable solution that can deployed yesterday: pair air conditioners with home batteries.
Whether or not that eventually happens, the mere conversation signals a massive shift in the way utilities could think about air conditioners. They wouldn’t be just a load demand problem, in other words. With built-in batteries, they could be part of a load demand solution.
“The homes we have and the fact that they all have air conditioning (or a heat pump) defines how the grid is sized, built, and operated today,” Hakan Yilmaz, Carrier’s chief technology and sustainability officer and head of its energy-solutions arm, told Canary Media. ”The [US’] peak load is about 750 gigawatts — that’s what the grid can manage today. Around 300 gigawatts of that is reserved for HVAC.”

As a graph, Yilmaz’ claims look something like this.

“We forecast US electricity demand fulfilled by the electric power sector will grow at an annual rate of just over 2% in 2025 and 2026, according to our Short-Term Energy Outlook,” writes Energy Information Administration (EIA) contributor Alex Mey. “Until 2020, electricity demand was relatively flat,” they add, noting that forecasted electricity demand growth is expected to be higher in areas with plans for large data centers and manufacturing facilities, like Texas and Northern Virginia.
Ironically, the two markets named in the EIA are markets that get extreme summer heat and, in Virginia’s case, humidity – and their energy grid solutions are far from being state-of-the-art. Yilmaz thinks his vision for battery-backed Carrier air conditioners solves for that.
With an estimated 30 million Carrier HVAC units installed in North American homes – representing more than 100 GW of potential flexible demand – the opportunity is significant. At scale, these systems could offer utilities a powerful tool to manage electricity demand.
“If we replace an HVAC unit today with a battery-integrated HVAC, the load of that HVAC unit never shows up at the peak for the next 15 years,” Yilmaz said. ”Use that electricity somewhere else.”
Yilmaz’s team at Carrier is piloting a modular battery that sits under or next to its outdoor air conditioning units to drive the HVAC systems during peak energy hours, which not only helps support the grid but can help reduce home energy costs by charging during overnight and off-peak hours when the electrical load is low and electrons are cheaper. It’s a solid idea, but there’s no reason to wait for Carrier to make the batteries
Heck, the 9to5Toys guys can probably show you a Raspberry Pi unit that’s ready to manage the whole thing for $39.99 or something during Prime Day (no promises). That’s my take, anyway — let us know yours in the comments section at the bottom of the page.

The German city of Karlsruhe is setting an example for sustainability in waste management by deploying a fleet of 18 Mercedes-Benz eEconic electric garbage trucks that are helping make the streets cleaner, quieter, and a lot less stinky.
Since the end of September, the city of Karlsruhe has been relying on Mercedes’ fully electric waste collection vehicles throughout, with none of the area-specific restrictions or limited rollout strategies for one or two trucks at a time that typically accompany stories like these. Instead, the city is using the Mercedes eEconics for the same stuff they’d use the diesel versions for: residual waste disposal, paper collection, and bulky waste collection.
Normal garbage duty, in other words. And, in such daily use, they do a great job. The trucks cover an average route distance of around 80 km (about 50 miles) on 112 kWh battery packs (usable capacity is ~97 kWh) which can be reliably completed in single-shift operation without intermediate charging — thanks, in part, to Mercedes’ efficient electric motors and regenerative braking that shines in the trucks’ typical stop-and-go duty cycles.
More than a single shift, in fact. The fleet managers report that after “a good 80 kilometers with around 60 stops on its daily route,” energy consumption was only around 35% of the battery capacity, meaning the charge level dropped from 100% to 65% and 64% respectively.

At the same time, CO₂ emissions are significantly reduced: depending on the area of application, each eEconic can save between 150 and 170 tons of CO₂ per year. This results in a total potential annual saving of around 1,200 tons of CO₂ emissions.
The purchase of the electric vehicles was funded by the Federal Ministry of Transport (BMV) as part of the guideline on the promotion of light and heavy commercial vehicles with alternative, climate-friendly drives and the associated refueling and charging infrastructure (KsNI). The funding guideline was coordinated by NOW GmbH, and applications were approved by the Federal Office for Logistics and Mobility.
Electrek’s Take
Look, you know me. There is absolutely ZERO chance that I’ll be able to remain objective about anything that’s putting down more than four thousand lb-ft of torque. Make that thing quieter, cleaner, and generally better for me and my community, and there’s even less of a chance of me saying anything critical about it.

Electreon just took a big step toward expanding wireless EV charging. The Israel-based company signed a memorandum of understanding (MoU) to acquire the assets of InductEV, a Pennsylvania-based firm known for its ultra-fast, high-power static wireless charging systems used by heavy-duty electric transit and freight fleets.
If the deal closes after due diligence and regulatory approvals, the combined company would bring together Electreon’s dynamic wireless charging tech – the kind that can charge vehicles while they drive – with InductEV’s high-power stationary systems. That would create one of the most complete wireless charging portfolios on the market, covering everything from passenger EVs to vans, buses, heavy-duty trucks, and even autonomous vehicles.
Electreon and InductEV together hold around 400 granted and pending patents, and have a lot of field experience across their respective projects. Electreon says that pairing its manufacturing capabilities and global footprint with InductEV’s ultra-fast tech will help streamline and speed up fleet electrification.
Both companies already work with major vehicle OEMs, which Electreon asserts will make integrating wireless charging into future vehicle platforms easier.

Electreon CEO Oren Ezer said the deal would combine the two companies into “a truly global powerhouse for wireless EV charging.” He added that “the decision by InductEV’s shareholders to invest in Electreon is a tremendous vote of confidence in our shared vision.”
InductEV CEO John F. Rizzo said, “Together, we’re combining world-class innovation with real-world experience to deliver even greater value to our North American and European customers and accelerate the shift to wireless power for sustainable commercial transportation.”

The Dolphin Surf is already one of Europe’s cheapest EVs, yet BYD may have an even more affordable electric car up its sleeve.
Is BYD launching the Racco mini EV in Europe?
BYD revealed the Racco at last month’s Japan Auto Show, its first EV designed exclusively for overseas markets.
The mini EV, or “kei car,” is launching in Japan, where over 1.55 million of them were sold last year, accounting for about a third of new vehicles sold.
Although Japan has been a brutal market for foreign brands to crack, BYD believes it may have an edge. The Racco measures 3,395 mm in length, 1,475 mm in width, and 1,800 mm in height, or about 600 mm longer than the Dolphin Surf.

That’s about the size of the Nissan Sakura EV, Japan’s best-selling electric car. Like the Sakura and most kei cars, the Racco has a boxy, upright stance. It has four doors, with the back two sliding open.

Powered by a 20 kWh battery pack, the mini EV is expected to have a driving range of around 180 km (112 miles).
BYD is using its Blade lithium iron phosphate (LFP) battery packs to keep costs down. Although prices have yet to be revealed, the Racco is expected to start at around 2.5 million yen ($18,000) in Japan, putting it on par with the Nissan Sakura.

If it launched in Europe, the Racco could go on sale for under £15,000 ($20,000), putting it on par with the Dacia Spring (£14,995) and Leapmotor T03 (£15,995). The BYD Dolphin Surf currently starts at £18,650 ($24,300).
Although it will arrive in Japan first, BYD may launch its smallest, cheapest EV in Europe after all. BYD’s vice president Stella Li suggested to Autocar that the Racco could play a key role globally as an affordable, entry-level EV.

“In Japan, we are already launching a kei car; we will be very interested to follow the EU regulation,” Li said, adding, “If there’s some space, we can bring that car here.”
The regulation Li is referring to is the new “E-car” segment that the European Commission president, Ursula Von der Leyen, called for in September.
Von der Leyen said that Europe “should have its own E-car,” where “E” stands for efficient, economical, and European, and added “we cannot let China and others conquer this market.”
The Racco could sit underneath the Dolphin Surf in BYD’s growing European lineup. However, the company is focusing on expanding hybrid options. Li said launching Racco was “not a topic” the company is immediately focused on.
The Seal U, Europe’s best-selling plug-in hybrid through September, will be the first vehicle built at BYD’s new factory in Turkey, as it seeks to gain an edge through local production.
