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.

Thanks to Trump’s repeated executive order attacks on US clean energy policy, nearly $8 billion in investments and 16 new large-scale factories and other projects were cancelled, closed, or downsized in Q1 2025.
The $7.9 billion in investments withdrawn since January are more than three times the total investments cancelled over the previous 30 months, according to nonpartisan policy group E2’s latest Clean Economy Works monthly update.
However, companies continue to invest in the US renewable sector. Businesses in March announced 10 projects worth more than $1.6 billion for new solar, EV, and grid and transmission equipment factories across six states. That includes Tesla’s plan to invest $200 million in a battery factory near Houston that’s expected to create at least 1,500 new jobs. Combined, the projects are expected to create at least 5,000 new permanent jobs if completed.
Michael Timberlake of E2 said, “Clean energy companies still want to invest in America, but uncertainty over Trump administration policies and the future of critical clean energy tax credits are taking a clear toll. If this self-inflicted and unnecessary market uncertainty continues, we’ll almost certainly see more projects paused, more construction halted, and more job opportunities disappear.”
March’s 10 new projects bring the overall number of major clean energy projects tracked by E2 to 390 across 42 states and Puerto Rico. Companies have said they plan to invest more than $133 billion in these projects and hire 122,000 permanent workers.
Since Congress passed federal clean energy tax credits in August 2022, 34 clean energy projects have been cancelled, downsized, or shut down altogether, wiping out more than 15,000 jobs and scrapping $10 billion in planned investment, according to E2 and Atlas Public Policy.
However, in just the first three months of 2025, after Trump started rolling back clean energy policies, 13 projects were scrapped or scaled back, totaling more than $5 billion. That includes Bosch pulling the plug on its $200 million hydrogen fuel cell plant in South Carolina and Freyr Battery canceling its $2.5 billion battery factory in Georgia.
Republican-led districts have reaped the biggest rewards from Biden’s clean energy tax credits, but they’re also taking the biggest hits under Trump. So far, more than $6 billion in projects and over 10,000 jobs have been wiped out in GOP districts alone.
And the stakes are high. Through March, Republican districts have claimed 62% of all clean energy project announcements, 71% of the jobs, and a staggering 83% of the total investment.
A full map and list of announcements can be seen on E2’s website here. E2 says it will incorporate cancellation data in the coming weeks.

Tesla has reportedly delayed the launch of its new “affordable EV,” which is believed to be a stripped-down Model Y, in the United States.
Last year, Tesla CEO Elon Musk made a pivotal decision that altered the automaker’s direction for the next few years.
The CEO canceled Tesla’s plan to build a cheaper new “$25,000 vehicle” on its next-generation “unboxed” vehicle platform to focus solely on the Robotaxi, utilizing the latest technology, and instead, Tesla plans to build more affordable EVs, though more expensive than previously announced, on its existing Model Y platform.
Musk has believed that Tesla is on the verge of solving self-driving technology for the last few years, and because of that, he believes that a $25,000 EV wouldn’t make sense, as self-driving ride-hailing fleets would take over the lower end of the car market.
However, he has been consistently wrong about Tesla solving self-driving, which he first said would happen in 2019.
In the meantime, Tesla’s sales have been decreasing and the automaker had to throttle down production at all its manufacturing facilities.
That’s why, instead of building new, more affordable EVs on new production lines, Musk decided to greenlight new vehicles built on the same production lines as Model 3 and Model Y – increasing the utilization rate of its existing manufacturing lines.
Those vehicles have been described as “stripped-down Model Ys” with fewer features and cheaper materials, which Tesla said would launch in “the first half of 2025.”
Reuters is now reporting that Tesla is seeing a delay of “at least months” in launching the first new “lower-cost Model Y” in the US:
Tesla has promised affordable vehicles beginning in the first half of the year, offering a potential boost to flagging sales. Global production of the lower-cost Model Y, internally codenamed E41, is expected to begin in the United States, the sources said, but it would be at least months later than Tesla’s public plan, they added, offering a range of revised targets from the third quarter to early next year.
Along with the delay, the report also claims that Tesla aims to produce 250,000 units of the new model in the US by 2026. This would match Tesla’s currently reduced production capacity at Gigafactory Texas and Fremont factory.
The report follows other recent reports coming from China that also claimed Tesla’s new “affordable EVs” are “stripped-down Model Ys.”
The Chinese report references the new version of the Model 3 that Tesla launched in Mexico last year. It’s a regular Model 3, but Tesla removed some features, like the second-row screen, ambient lighting strip, and it uses fabric interior material rather than Tesla’s usual vegan leather.
The new Reuters report also said that Tesla planned to follow the stripped-down Model Y with a similar Model 3.
In China, the new vehicle was expected to come in the second half of 2025, and Tesla was waiting to see the impact of the updated Model Y, which launched earlier this year.
Electrek’s Take
These reports lend weight to what we have been saying for a year now: Tesla’s “more affordable EVs” will essentially be stripped-down versions of the Model Y and Model 3.
While they will enable Tesla to utilize its currently underutilized factories more efficiently, they will also cannibalize its existing Model 3 and Y lineup and significantly reduce its already dwindling gross margins.
I think Musk will sell the move as being good in the long term because it will allow Tesla to deploy more vehicles, which will later generate more revenue through the purchase of the “Full Self-Driving” (FSD) package.
However, that has been his argument for years, and it has yet to pan out as FSD still requires driver supervision and likely will for years to come, resulting in an extremely low take-rate for the $8,000 package.
