The power needs of artificial intelligence and cloud computing are growing so large that individual data center campuses could soon use more electricity than some cities, and even entire U.S. states, according to companies developing the facilities.
The electricity consumption of data centers has exploded along with their increasingly critical role in the economy in the past 10 years, housing servers that power the applications businesses and consumers rely on for daily tasks.
Now, with the advent of artificial intelligence, data centers are growing so large that finding enough power to drive them and enough suitable land to house them will become increasingly difficult, the developers say. The facilities could increasingly demand a gigawatt or more of power — one billion watts — or about twice the residential electricity consumption of the Pittsburgh area last year.
Technology companies are in a “race of a lifetime to global dominance” in artificial intelligence, said Ali Fenn, president of Lancium, a company that secures land and power for data centers in Texas. “It’s frankly about national security and economic security,” she said. “They’re going to keep spending” because there’s no more profitable place to deploy capital.
Renewable energy alone won’t be sufficient to meet their power needs. Natural gas will have to play a role, developers say, which will slow progress toward meeting carbon dioxide emissions targets.

Regardless of where the power comes from, data centers are now at a scale where they have started “tapping out against the existing utility infrastructure,” said Nat Sahlstrom, chief energy officer at Tract, a Denver-based company that secures land, infrastructure and power resources for such facilities.
And “the funnel of available of land in this country that’s industrial zone land that can fit the data center use case — it’s becoming more and more constrained,” said Sahlstrom, who previously led Amazon’s energy, water and sustainability teams.
Beyond Virginia
As land and power grow more limited, data centers are expanding into new markets outside the long-established global hub in northern Virginia, Sahlstrom said. The electric grid that serves Virginia is facing looming reliability problems. Power demand is expected to surge, while supply is falling due to the retirement of coal- and some natural gas-powered plants.
Tract, for example, has assembled more than 23,000 acres of land for data center development across the U.S., with large holdings in Maricopa County, Arizona — home to Phoenix — and Storey County, Nevada, near Reno.
Tract recently bought almost 2,100 acres in Buckeye, Arizona with plans to develop the land into one of the largest data center campuses in the country. The privately-held company is working with utilities to secure up to 1.8 gigawatts of power for the site to support as many as 40 individual data centers.
For context, a data center campus with peak demand of one gigawatt is roughly equivalent to the average annual consumption of about 700,000 homes, or a city of around 1.8 million people, according to a CNBC analysis using data from the Department of Energy and Census Bureau.
A data center campus that size would use more power in one year than retail electric sales in Alaska, Rhode Island or Vermont, according to Department of Energy data.
A gigawatt-size data center campus running at even the lower end of peak demand is still roughly comparable to about 330,000 households, or a city of more than 800,000 people — about the population of San Francisco.
The average size of individual data centers operated by the major tech companies is currently around 40 megawatts, but a growing pipeline of campuses of 250 megawatts or more is coming, according to data from the Boston Consulting Group.
The U.S. is expected see a growing number of data center campuses of 500 megawatts or more, equivalent to half a gigawatt, in the 2030s through mid-2040s, according to the BCG data. Facilities of that size are comparable to about 350,000 homes, according to CNBC’s analysis.
“Certainly the average size of the data centers is increasing at a rapid pace from now to 2030,” said Vivian Lee, managing director and partner at BCG.
Community impact
Texas has become an increasingly attractive market due to a less burdensome regulatory environment and abundant energy resources that are more easily tailored to specific sites, Sahlstrom said. “Texas is probably the world’s best experiment lab to deploy your own power solution,” the energy officer said.
Houston-based Lancium set up shop in 2017 with the idea of bringing large electric loads closer to abundant renewable energy resources in west and central Texas, said Fenn, the company’s president. Originally focused on cryptocurrency mining, Lancium later shifted its focus to providing power for artificial intelligence with the advent of ChatGPT in late 2022.
Today, Lancium has five data center campuses in various stages of development. A 1,000-acre campus in Abilene is expected to open in the first quarter of 2025 with 250 megawatts of power that will ramp up to 1.2 gigawatts in 2026.
The minimum power requirement for Lancium’s data center customers is now a gigawatt, and future plans involve scaling them up to between three and five gigawatts, Fenn said.
For data centers that size, developers have to ensure that electricity costs in neighboring communities don’t rise as a consequence and that grid reliability is maintained, Fenn said. Pairing such facilities with new power generation is crucial, she said.
“The data centers have to partner with utilities, the system operators, the communities, to really establish that these things are assets to the grid and not liabilities to the grid,” Fenn said. “Nobody’s going to keep approving” such developments if they push up residential and commercial electric rates.
Renewables not enough
Data center campuses run by publicly-traded Equinix are rising to several hundred megawatts from 100- to 200 megawatts, said Jon Lin, general manager for data center services at the company. Equinix is one of the largest data center operators in the world with 260 facilities spread across 72 metropolitan areas in the U.S. and abroad.
Developers prefer carbon-free renewable energy, but they also see solar and wind alone as unable to meet current demand due to their reliance on changing weather conditions.
Some of the most critical workloads for the world’s economy, such as financial exchanges, run at data centers operated by Equinix, Lin said. Equinix’s data centers are online more than 99% of the time and outages are out of the question, the executive said.
“The firmness of the power is still incredibly important for these data centers, and so doing that solely off of local renewables is candidly just not an option,” Lin said.
The major technology companies are some of the largest purchasers of renewable power in the U.S., but they are increasingly turning to nuclear in search of more reliable sources of electricity. Microsoft is supporting the restart of the Three Mile Island nuclear plant outside Harrisburg, Pennsylvania through a power purchase agreement. Amazon and Alphabet’s Google are investing in small nuclear reactors.
But building new nuclear reactors is expensive and fraught with delays. Two new reactors in Georgia recently came online years behind schedule and billions of dollars over budget.
In the short run, natural gas will fuel much of the power demanded by data centers, Lancium’s Fenn said. Gas is the main, short-term power source providing the reliability these facilities require, Boston Consulting Group’s Lee said.
Investments could be made in new gas generation that adds carbon capture and battery storage technology over time to mitigate the environmental impact, Lee said.
The industry hopes that gas demand will taper off as renewables expand, battery storage costs come down and AI helps data centers operate more efficiently, Fenn said. But in the near term, there’s no question that data center expansion is disrupting technology companies’ emissions targets, she said.
“Hopefully, it’s a short term side step,” Fenn said of stepped-up natural gas usage. “What I’m seeing amongst our data center partners, our hyperscale conversations, is we cannot let this have an adverse effect on the environmental goals.”
Note: CNBC analysis assumes a data center campus is continuously utilizing 85% of its peak demand of a gigawatt throughout the year, for a total consumption of 7.4 billion kilowatt-hours. Analysis uses national averages for household electricity consumption from EIA and household size from Census Bureau.
The electric restomod experts at Lunaz have turned their talents towards the classic Rolls-Royce Phantom V limousine – and the result is exactly the kind of smooth, quiet, and luxurious ride RR’s founders would have built.
Rolls-Royce’ founders dedicated their engineering talents to developing cars that were smooth, quiet, and adequately powerful – and they spared no expense. The company Charles Rolls and Henry Royce founded would eventually go on to develop some of the most powerful and celebrated combustion engines of the twentieth century … but the car they wanted to build? It was electric.
“The electric car is perfectly noiseless and clean,” Charles Rolls told The Motor-Car Journal, all the way back in April of 1900. (!) “There is no smell or vibration, and they should become very useful when fixed charging stations can be arranged. But for now, I do not anticipate that they will be very serviceable – at least for many years to come.”
Well, 125 years seems like “many” to – and the talented craftspeople and engineers at Lunaz seem to agree. Meet the Lunaz Rolls-Royce Phantom V limousine.
It’s glorious
Lunaz says it’s true to Rolls’ vision “down to the smallest, most indulgent detail.” To that end, the company re-trims the modern heated and ventilated seats in fine leathers, hand-cut and stitched to the buyers’ specifications. In the rear, the center console can be ordered with a built-in cigar humidor, a cocktail bar, or some other custom-spec, lockable storage lined in suede and polished walnut (translation: guns and drugs, probably).
When reimagining the Rolls-Royce Phantom V, (we) started by understanding the essence of its original design. Every component and dynamic was scrutinized to identify where thoughtful innovation could truly elevate the experience. The result is a harmonious blend of modern advancements and original mastery, unlocking new levels of performance, reliability and refinement while honoring Rolls-Royce’ classic soul.
Like the classic Bentley S2 Continental the company revealed in 2023, the big electric Roller is equipped with an 80 kWh battery pack sending electrons to a proprietary Lunaz drivetrain featuring 400 hp worth of electric motors delivering a silky-smooth 530 lb-ft of torque, good for a 0-100 km/h (62 mph) swoosh in about seven seconds. Of course, why you’d ever ask your driver to perform such plebian stunts is simply beyond me.
The transformation and restoration took more than 5,500 man-hours to complete, and involve more than 11,000 new or reconditioned components at a cost of more than £1 million (about $1.35 million US). If you place your order today, you should get yours in 18-24 months.

Fortescue has taken the wraps off a prototype of its proposed “Infinity Train” electric locomotive, making the 1,100 km (about 685 miles) trip from Perth to the Pilbara and marking a major milestone in the decarbonization of the company’s heavy haul operations.
Co-developed with the locomotive experts at Downer Group, Fortescue revealed its concept for a battery electric “Infinity Train” back in March of 2022. At the time, the company promised a “world’s first” iron ore train capable of fully charging its batteries through regenerative braking. The two companies claimed the clever technology would create a self-sustaining, zero-emission rail system powered entirely by the force of gravity during the train’s loaded downhill travels.
This week, the concept went from the drawing board to the real world, completing an 1,100 km trip across Australia and proving itself to be up to the task of handling the grueling demands of Fortescue’s massive mining operations.
“We’re thrilled to see our battery electric locomotive prototype arrive in the Pilbara,” said Ellie Coates, CEO of Fortescue Zero. She added that the achievement, using zero fossil fuels, “represent(s) a major step in Fortescue’s journey to Real Zero.”
The Fortescue Infinity Train uses the energy produced by slowing the loaded train on downhill sections of the company’s 385 mile private, heavy-haul rail network to recharge its battery systems. That energy is enough to bring the unloaded train back to the mine, eliminating the need for external charging infrastructure or additional renewable energy sources, making the train almost entirely self-sufficient.
Fortescue says the deployment of the Infinity Train concept at its mines will eliminate more than 82 million liters of diesel fuel consumption (about 21 million gallons, which ChatGPT tells me amounts to about 235,200 tons of CO₂ emissions).
That change alone would eliminate about 11% of Scope 1 emissions annually for Fortescue all on its own, putting it well on its way to its stated goal of achieving “Real Zero” emissions-free operations.
Electrek’s Take
Using gravity to charge up heavily-laden mining vehicles on downhill runs is an idea that’s been put into practice for years, with great success wherever the topography allows (since 2017, at least). Combining that clever use of gravity, traction braking, and battery storage for use on a rail system like this just seems smart, and it makes me think we’re just scratching the surface of all the clever ways electrification and battery storage will eventually get put to use.
I wonder what would happen if you threw some battery electric rail cars into the mix, as well!? You guys are smart, head down to the comments and let me know (and, while you’re there, help me check ChatGPT’s math on those carbon emissions).

A new study by the Pembina Institute shows that a third of the commercial trucks and vans on Toronto’s roads are ready to electrify today – while nearly half could be electrified by 2030.
A new analysis by the Pembina Institute titled Electrifying Fleet Trucks: A case study estimating potential in the GTHA finds that as many as a third of trucks in the Greater Toronto and Hamilton Area (GTHA) could go electric today, rising to more than half by early 2030s — insulating businesses from rising fuel costs and reducing harmful air pollution that drives up health care costs. What’s more, the report found that battery range and charging access are less of a barrier than expected.
“Real-world travel data from Canadian trucks, collected over summer and winter months, shows that electrification is possible today,” says Chandan Bhardwaj, Senior Analyst at the Pembina Institute. “In fact, with a staggered approach, the GTHA — home to over half the province’s vehicle stock — could reach 50% sales for lighter trucks by 2030, helping offset lower adoption rates for heavier trucks.”
So, what’s holding back electric vehicle adoption? According to the study’s authors, it’s a matter of public policy. But without the right policies in place, the study argues, businesses face unnecessary hurdles in making the switch.
“Our analysis shows that Ontario has a clear path to accelerating the transition to zero-emission trucks — unlocking economic opportunities, improving public health and positioning itself as a leader in clean transportation,” says Adam Thorn, Transportation Director at the Pembina Institute. “With the right policies in place, businesses can reap the benefits of lower costs while the province strengthens its manufacturing sector and energy security.”
We already knew this
If all of this sounds a bit familiar, it’s probably because you’ve heard this before. The California Air Resource Board (CARB) came to very similar conclusions in their report, titled, Determining energy use patterns and battery charging infrastructure for zero-emission heavy-duty vehicles and off-road equipment.
CARB staff believe that several heavy-duty ZE vocational trucks are ready to be electrified because of their low daily mileage demands (<100 mi). Long-haul Class 8 trucks continue to be a challenge to fully electrify because of the long operation range (300+ mi) and on-demand charging need.
In fact, the California study came to almost the exact conclusion that the Toronto study did when examining the heavy-duty Class 7 and 8 EV market. Which is to say: it’s not a question of capability, but a question of availability.
“The availability of on-road heavy-duty ZE trucks has increased in recent years,” reads the report. “But their numbers remain significantly lower than their diesel and natural gas counterparts. As of 2022, an estimated 2,300 on-road ZE medium- and heavy-duty vehicles are operating in California, with the vast majority located in South Coast Air Bassin (Figure 1). On-road heavy-duty ZE transit buses account for the majority of all on-road heavy-duty ZEVs in California, but, as of 2023, sales of ZE heavy-duty trucks and medium-duty step vans have outpaced other vocations, indicating that these vehicles will be more prevalent in fleets in the near future.”
That’s proven to be true, with sales of Class 2 vans and other medium-duty EVs rapidly outpacing the general public’s adoption of EVs as new options became available in 2024, with no signs of slowing down in 2025 (at least, where the right policies are in place).
Here are some of the key takeaways from the Pembina Institute study from the Toronto truck market. Obviously, it won’t directly translate to every city’s truck fleet – but take a look at Toronto’s demographics and some of the key variables involved (truck size, average loads, miles driven, etc.) and you might be surprised at how similar your city and your fleet might be.
- Businesses can save up to 40% of fuel and maintenance costs by switching to electric trucks.
- Electric trucks eliminate tailpipe emissions, cutting harmful air pollution and improve public health.
- Traffic related air pollution in the Greater Toronto and Hamilton Area leads to 700 premature deaths and 2,800 hospitalizations every year, costing health care system $4.6 billion annually.
- Ontario’s Driving Prosperity plan highlights the need for increased electrification, while the City of Toronto is targeting 30% of all registered vehicles to be electric by 2030.
- Governments worldwide are embracing electrification, setting ambitious sales targets for zero-emission vans and trucks.
- By 2030, jurisdictions like Europe, China, California, British Columbia and Quebec aim for about 35% of new truck sales to be zero-emission, ramping up to nearly 100% by 2040.
