Artificial intelligence could strain the U.S. electric grid, as power demand from data centers is poised to surge in the coming decade just as supply is falling due to the rapid retirement of coal-fired plants.

Data centers in the U.S. alone could consume as much electricity as some major industrialized economies produce by 2030, as they proliferate not just in number but also in the scale of their power needs.

The computer warehouses that power the Internet and increasingly AI could require up to 400 terawatt hours of electricity by 2030, according to an August report from Mizuho Securities.

That’s more than the total electricity production of the United Kingdom in 2022, according to data from the International Energy Agency.

Data center developers are knocking at the door of the nation’s utilities at the same time many of these power companies are retiring coal plants as part of the transition away from fossil fuels. But the waiting list to bring clean energy, primarily solar and wind, onto the grid to replace coal is long and renewables are less reliable.

PJM Interconnection, the largest grid operator in the U.S., warned in July that the reliability of the system is a growing concern as coal plants close faster than new power generation is built.

PJM serves 13 states primarily in the Mid-Atlantic region, including northern Virginia, the largest data center market in the world. Resources in areas of Virginia are insufficient and the transmission system is constrained, limiting the ability to import power from elsewhere, according to PJM.

Yet data center “growth is accelerating in orders of magnitude, driven by the number of requests, the size of each facility and the acceleration of each facility’s ramp schedule to reach full capacity,” Dominion Energy CEO Robert Blue told investors on the company’s earnings call on Aug. 1.

Electrification of economy

In addition to data centers, manufacturing is returning to the U.S. and the broader economy is electrifying. Recent auction prices to bring new power capacity to the PJM power pool have surged more than 800% as a consequence of rising demand and limited supply.

“The market has already made one transition from coal to gas,” Susan Buehler, a spokesperson for PJM, told CNBC. “We see this energy transition is here. We just see that the forces around it are happening faster than the renewable energy transition is happening.”

“So we see a potential gap, and that’s what the market is signaling,” Buehler said.

PJM has forecast that electricity demand surge will surge nearly 40% by 2039 in its 369,000-square mile service area. Meanwhile, 40 gigawatts of existing power generation is at risk of retirement by 2030, or about 21% of PJM’s current installed capacity.

While there are 290 gigawatts of renewable projects waiting to get connected to the grid, in the past only about 5% of such projects have actually been built, according to PJM.

About 38 gigawatts of renewable energy have been approved for connection and another 72 gigawatts are coming in the first quarter of 2025, Buehler said, but the projects are not being built quickly enough due the challenges developers are facing on the ground.

Buehler said developers “can’t get their projects sited, there are supply chain delays, and there are financing issues.”

Step-change in investment needed

Utilities that operate in PJM have disclosed at least 50 gigawatts of potential data center demand during their recent earnings calls, though CEOs have cautioned there could be some duplication in the numbers.

About 29% of current data center electricity demand in the U.S. is located within PJM’s territory, according to Mizuho. Some 25% of data center power demand in the nation is in Virginia.

American Electric Power, one of the largest electric utilities in the U.S., has commitments for more than 15 gigawatts of demand from data centers through the end of the decade, interim CEO Benjamin Fowke told investors on the company’s second-quarter earnings call earlier last month.

That level of demand is equivalent to more than 40% of the peak electric load of 35 gigawatts across AEP’s entire system at the end of last year, according to Fowke. AEP serves 5.6 million customers in 11 states in the Midwest and South.

“These are far from just inquiries,” Fowke told investors. “These are serious customers that want to get on the grid and are willing to financially commit to do what it takes to get on the grid.”

Fowke testified to Congress in May that demand for electricity in some parts of the U.S. is already outstripping available capacity on the grid. The former CEO of Xcel Energy said that requests from large customers would more than double the current peak demand on the utility’s system.

“It took over 100 years of planning and building to create our current system, and a step-change in infrastructure investment on an accelerated timeline will be required to serve even a fraction of this future demand in a reliable manner,” Fowke told the Senate Committee on Energy and Natural Resources.

The cost of building new infrastructure to meet the demand is expected to reach hundreds of billions of dollars, Fowke said.

In the past, a large manufacturing facility might need 100 megawatts of electricity — equivalent to about 100,000 homes, Fowke told Congress. It is now increasingly common for a single data center to need anywhere from three to 15 times that amount of power, the CEO said.

Dominion Energy regularly gets requests to support data center campuses that require as much as several gigawatts of power, Blue said in May. That’s larger than the average capacity of a nuclear reactor in the U.S.

Going around the grid

One of the many challenges in connecting this kind of demand to the grid is that it can take up to a decade to decide t he exact route a transmission line will take, get the necessary permits and build it, Edison Electric Institute senior vice president for customer solutions Phil Dion told Congress in June.

As a result, tech companies that are building data centers are increasingly looking at directly connecting their facilities to large power resources, such as nuclear plants, rather than waiting to access the grid. But that approach is already facing controversy.

Amazon Web Services purchased a data center campus in March from Talen Energy for $650 million that will be powered directly by the Susquehanna nuclear plant in Pennsylvania. It was viewed by some in the industry as a landmark agreement that could pave the way for more nuclear-powered data centers.

But AEP has challenged the agreement before the Federal Energy Regulatory Commission, warning that such arrangements could further constrain supply on the electric grid.

Constellation Energy CEO Joe Dominguez told investors earlier this month that hooking data centers directly to nuclear reactors is the fastest and most cost effective solution. Constellation operates the largest portfolio of nuclear plants in the U.S.

“The notion that you could accumulate enough power somewhere on the grid to power a gigawatt data center is frankly laughable to me,” Dominguez said on Constellation’s August earnings call.

Utility executives have warned that failure to meet rising demand from data centers could affect the entire U.S. economy.

“If I can’t get that power capacity online, I cannot do the data center. I cannot do the manufacturing. I can’t grow the core businesses of some of the largest corporations in the country,” Petter Skantze, vice president of infrastructure development at NextEra Energy Resources, the renewable energy unit of NextEra Energy, said at a conference in New York City in June.

“The stakes are really, really high,” Skantze said. “This is a new environment. We have to get this right.”

Volvo DD25 Electric compactor gets to work in Yolo County, California

Volvo DD25 Electric compactor gets to work in Yolo County, California

California County Adds First Electric Volvo DD25 Compactor to Fleet

Yolo County, California depends on its climate for continued agricultural success. As such, the county’s leaders are taking environmental stewardship seriously by aiming for full carbon neutrality by 2030. To help achieve that goal, they’re putting zero-emission machinery like the Volvo DD25 Electric compactor to work.

We got our first chance to sample the DD25 Electric at Volvo Days last summer, where the all-electric tandem roller’s vibrating drums impressed dealers and end users alike. It was no surprise, then, that when Yolo Country fleet superintendent, Ben Lee, when shopping for a compactor the DD25 Electric was high on his list.

“The DD25 Electric will help us achieve our goals in several ways,” explains Lee. “By reducing emissions, lowering noise levels, being more energy-efficient, improving working conditions and promoting environmentally friendly practices … we’ll use it to compact soil, gravel and other base materials for road and foundation projects, as well as rolling out and leveling asphalt during road construction and resurfacing.”

To help Lee handle those various projects, the Volvo’s drum frequency can be adjusted from 3500 vpm (55 Hz) to 4000 vpm (67 Hz) to cater to different applications and materials.

The DD25 Electric offers other benefits, as well – like a 20 kWh 48V battery that offers up between six and eight hours of continuous operation. That’s could be several shifts in the kind of conditions Yolo’s work crews will encounter, meaning it will only have to get put to bed (Volvo recommend overnight AC charging) two or three times a week.

Getting power to the compactor, too, is something Yolo is considering. “There are some remote areas in the county, so we’re looking into a mobile, self-contained charging unit as well,” explains Lee, apparently referencing the Volvo PU130 mobile battery. “So we wouldn’t have to bring the machine back to the yard each night during a long-term project.”

Yolo County views electric equipment as an essential step in reducing emissions and energy consumption, especially as communities work towards stricter regulations and sustainability goals.

Electrek’s Take

This press release came to us ahead of the devastating wild fires in Southern California that are dominating headlines right now – so much so that I effectively sat on the news for a few days, debating whether or not we should even be talking about a California news story that isn’t about the fires right now.

But I realized: this story is about the fires. Climate change driven by combustion and carbon emissions is driving climate change and that’s making fires like these possible … and I should have run it sooner.

CES2025 | Kubota brings electric equipment, robots, and hydrogen to CES

Kubota Unveils Wide Range of Customer Solutions at CES® 2025, Brings More Connectivity and Automation to Its Equipment Portfolio.

Kubota came to this year’s CES with a sprawling display filled with electric equipment, hydrogen gensets, and an onslaught of commercial robots ready to mow, farm, dig, and build. If you weren’t impressed by Kubota’s display this year, you weren’t paying attention.

Kubota gave us a sneak peek of its KATR farm robot – itself a smaller, updated version of last year’s New Agri Concept – before the doors officially opened last week. Kubota’s robotic farm buddies promise to be able to quietly and autonomously haul stuff from one end of the farm to another, or pull carts and specialized implements along predetermined paths.

KATR uses self-leveling technology and active suspension to ensure its cargo deck stays level when working on the sort of uneven terrain found on farms or construction sites.

That doesn’t mean the New Agri Concept is dead, though. Agri Concept 2.0 debuted as an electric tractor concept offering AI-powered automation and a fully electric powertrain. The new version features a Lite Brite-style “grille” that it uses to communicate its current mode, direction, and other important information with the people it shares a job site with.

On the more practical side, Kubota showed off its KX38-4e Electric compact excavator. First shown in overseas markets in 2022, the KX38-4e Electric features a 49.2 kWh lithium-ion battery that’s good for up to five hours of continuous operation. More than enough to complete a typical day of work on a construction site when you factor out idle time.

An onboard DC fast charger means it can be quickly recharged between shifts, too. But when there’s no grid power on the site, charging can be a challenge. That’s why Kubota has hydrogen genset for zero-emission on-site power generation.

Looked at individually, each of the new electric Kubota products on display might be impressive. The real magic, though, is in the way the Kubota machines work together as a holistic job site or farm solution.

“At Kubota, we believe that truly listening to our customers drives innovation in every aspect of what we call the ‘Work Loop’,” explains Brett McMickell, Chief Technology Officer of Kubota North America. “The Work Loop — an essential cycle of assessing, analyzing, and acting — has always been fundamental to effective task management. With the integration of advanced sensors, AI-driven analysis, networking protocols, automation, and robotics, we are enhancing this cycle to be more seamless and efficient than ever before.”

That was obvious in some of the more thoughtful implements and attachments on display, including a Smart Plant Imager that uses advanced robotics and “hyper-spectral imaging” cameras to capture real-time data and insights on a plant-by-plant level – as well as a Smart Autonomous Sprayer and Robotic Pruner that that classifies buds and canes based on position and fruiting potential, it optimizes production precision and accuracy.

The more you look, the more impressive Kubota’s farming solution gets. “We will continue to learn from many of our customers across segments to iterate the next product and technology solution that will help them manage tomorrow’s challenges and grow their businesses,” McMickell added. “This is how Kubota works to make a better quality of life for individuals and society.”

There was more, of course. Autonomous versions of the company’s electric zero-turn mower with GPS-powered route memory, fun accessory baskets for the robots, even a weird, jet engine looking thing that I forgot to ask about (below). I was genuinely impressed, in other words, and can’t wait to see what Kubota comes up with next year.

Tenways C GO 600Pro commuter e-bike is as smooth as it gets

The e-bike industry has stalled a little bit in terms of features, and with harsh new legislation coming in from places like California, maybe it is time to start looking at e-bikes that are light, efficient, and smooth rather than how much wattage they can output. The Tenways CGO 600Pro, which comes in at just 37 pounds, is a model e-bike you should keep an eye on…

The CGO 600Pro comes in 2 flavors: a carbon belt single-speed version that Micah reviewed and this one, which is a chain and 8-speed Shimano gears. The belt drive is going to win out on simplicity and weight but if you are expecting to get close to the ‘class 1’ top speed of 20mph or need to go up some significant hills, you’ll want to opt for the chain/gear version here.

[embedded content]

One thing I love about this bike is the tradeoff decisions. These keep the price low and weight down while still providing a great ride. The spec sheet overall is solid but not top-shelf.

Tenways CGO600 Pro tech specs (chain/geared version)

Motor: 350 Watt rear hub motor with 45 Nm of torque
Top speed: 20 mph (32 km/h)
Range: Claimed up to 53 miles (85 km)
Battery: 36V 10Ah (360 Wh)
Weight: 37 lb (16.8 kg, over 40lbs with fenders, kickstand, etc)
Frame: 6061 aluminum alloy
Tires: CST Puncture-proof 700*45C-size Tires
Brakes: Tektro dual-piston hydraulic disc brakes
Gearing: Shimano 8-Speed Claris
Extras: Compact LED display, 4 pedal assist levels, slim fender set, kickstand, internally routed cables, LED lighting, removable battery, Tenways app integration, torque sensor, four color options

No Throttle?

Note that as a class 1 e-bike, neither belt/chain version has a throttle. While this may be controversial to some, it not only simplifies the bike, it makes it a Class 1, which will be legal in the most places. I tend to think of no throttle as a “foot throttle” and for the commuter application, this will serve well. Would I appreciate a throttle on a hill start? Perhaps.

The idea of this bike is to just enhance your pedal bike experience. You are going to get some exercise on this bike versus a bike that is a glorified low-power moped that runs on throttle with vestigial pedals.

More importantly, the torque sensor here is phenomenal; I mean, it is probably the best torque sensor I’ve ridden connected to a rear hub motor. The acceleration is smooth and strangely powerful for the 350W/45nm motor. Significant hills are a breeze, and this is one of the few bikes where I forget that I’m using an e-bike sometimes (until I look down and I’m going 20mph with little effort). Hills are also where the gearing really helps.

The tires are also the perfect size for a commuter with puncture resistance and treads that will do OK in rain and snow.

The bike itself is also very stealthy in terms of showing that it is a powered e-bike. The small 36V, 10Ah battery is integrated magnificently into the narrow downtube of the bike. All of the cables are integrated into the bike frame for a super-clean look. The rear hub motor is small but packs a punch. Many people won’t even recognize this as an e-bike. While I’m proud to be riding an e-bike around, perhaps some people would like to keep that on the down-low.

Brakes are great with hydraulic Tektros clasping against 160mm rotors in front and back. It is such a light bike that stopping can be jarring.

Assembly was super easy and took about 30 minutes with the included tool set. The battery came about 40% charged but was ready to go within a few hours with the 3A charger. Shoutout to Tenways for using a water-resistant standardized barrel charger adapter and not some proprietary adapter so that I can use one from another bike when I inevitably lose it.

Electrek’s take

The Tenways CGO600 is a fantastic light, clean, stiff and smooth e-bike that I have 0 reservations about recommending. While the battery and motor are small, they power the light bike admirably and for around 50 miles (your mileage will vary).

Currently there is a $200 off promotion code “HAPPY2025TW” at checkout bringing the CGO600Pro down to $1399 which is an amazing price for this bike:
