(Bloomberg) — Weeks after ChatGPT was unleashed on the world in November 2022, sustainability executives at Microsoft Corp. realized they’d an enormous drawback.
On the tech large’s 500-acre campus in Redmond, Washington, groups started holding common “triage” conferences to confront severe questions posed by the synthetic intelligence growth: The place would the corporate discover the gigawatts — only one gigawatt can energy practically 750,000 US houses — wanted for knowledge facilities? And the way might Microsoft probably safe that additional vitality whereas nonetheless making progress towards a long-standing objective of going carbon-negative?
The AI discussions have been “fascinating and terrifying all on the identical time,” mentioned Brian Janous, who served till August 2023 as Microsoft’s vp of vitality. Microsoft and different main tech firms, he mentioned, needed to “have a look at the local weather commitments they set and say, ‘Can I nonetheless do that?’”

Almost three years later, Microsoft and its rivals, together with Amazon.com Inc., Meta Platforms Inc., and Alphabet Inc.’s Google, are nonetheless struggling to reply that query. On one hand, they’re attempting to acquire each electron potential to energy their trillion-dollar wager on AI. On the opposite, they’re attempting to remain true to a objective of attaining net-zero carbon emissions by 2040 or sooner.
“There’s no query that the present push to develop AI infrastructure is placing a pressure on the local weather commitments of the massive tech firms, all of which have been made previous to the appearance of AI,” Janous mentioned in an interview. After leaving Microsoft, he co-founded Cloverleaf Infrastructure, which companions with utilities to develop clean-powered websites that provide the most important data-center suppliers.
US President Donald Trump isn’t making this problem any simpler. Since taking workplace, he’s slashed federal funding for inexperienced initiatives, akin to wind and photo voltaic, and signaled his help for powering AI with turbines that use fossil fuels, together with growing old coal-fired vegetation. Cautious of irritating their greatest ally in Washington, tech leaders to date have shunned publicly difficult the president over his marketing campaign in opposition to renewables.
For now, the so-called hyperscalers proceed to purchase clear vitality at a file tempo, with Meta, Amazon, Google and Microsoft rating as the most important company signers of energy buy agreements with renewable suppliers. Collectively they accounted for 9.6 gigawatts of US clear vitality purchases within the first half of 2025, amounting to 40% of the worldwide complete, based on the most recent BloombergNEF knowledge.
That quantity falls woefully in need of the 362 gigawatts of extra energy the {industry} is projected to want worldwide by 2035 to maintain its rising knowledge middle fleet, based on BNEF. With huge stress from Wall Avenue to ship on AI investments, firms can’t afford to let vitality be a limiting issue and are pursuing an all-of-the-above technique on electrical energy sources.
AI’s affect is already exhibiting up in sustainability studies. Meta, Google, Amazon and Microsoft disclosed that their carbon emissions went up 64%, 51%, 33% and 23% respectively, of their newest local weather filings in comparison with their benchmarks from earlier than ChatGPT’s launch. Microsoft explicitly blamed “growth-related elements akin to AI and cloud growth.”

Inside Microsoft, stress between longstanding local weather pledges and the insatiable vitality wants of AI left the sustainability groups mired in uncertainty, based on two former managers who left the corporate earlier this yr. Talking on situation of anonymity, the previous managers described Microsoft’s local weather priorities as always shifting within the face of its urge for food for electrical energy.
A key supply of pressure was over issues that Microsoft risked a public backlash if it seemed to be abandoning its local weather targets in any approach, making a “suffocating stage of management” that paralyzed employees, one of many former managers mentioned. Stories have been dissected to make sure they adhered to an evolving firm line, with particular person phrases in memos and different paperwork turning into landmines that would “blow up” conversations, the individual mentioned.
Including to the stress, the opposite former supervisor mentioned, have been industry-wide workforce reductions in 2023 that reduce practically 200,000 jobs, which destabilized local weather groups as they labored on one of many hardest issues in tech: find out how to procure sufficient vitality, sustainably.
In an announcement, Microsoft’s chief sustainability officer, Melanie Nakagawa, mentioned the corporate “stays dedicated to assembly our local weather targets of being carbon unfavourable, water optimistic and nil waste by 2030 whereas defending ecosystems. As we be taught and adapt, we’re persevering with to develop our world clear vitality portfolio, constructing markets by investing in new local weather know-how options, and empowering others with know-how to construct a extra sustainable future.”
Largest Bottleneck
On a latest podcast, Microsoft Chief Government Officer Satya Nadella mentioned the provision of energy, slightly than the provision of semiconductors, accounted for the greatest bottleneck in knowledge middle capability. By some estimates, the vitality wants of present and deliberate AI infrastructure within the US can’t be met with present provide.
Dave Stangis, a senior govt at Apollo World Administration who has led the agency’s sustainability technique for the previous 4 years, mentioned final month that the quantity of vitality required to energy AI knowledge facilities is so huge that assembly that want could also be greater than a lifetime away.
Consequently, massive tech firms have been shopping for extra nuclear and geothermal vitality to fulfill the wants of their increasing AI infrastructure, based on BNEF knowledge. On the identical time, haunted by the danger of dropping energy for even a minute and pushed by the will to win the AI race, some firms are additionally exploring what’s generally known as behind-the-meter energy, the place a technology plant sits within the knowledge middle’s yard.
“They need a brand new useful resource, one thing that’s not already on the grid, that’s not already spoken for,” mentioned Elaine Walsh, who leads the facility group for the legislation agency Baker Botts. She added that “virtually all” of the brand new improvement work she does is for fuel energy.
Meta’s Hyperion Venture
That’s the technique Meta is utilizing because it makes an attempt to get its massive data center in Louisiana up and operating as shortly as potential.
The challenge, dubbed Hyperion, is a 4 million-square-foot complicated on 2,250 acres in rural Louisiana that’s anticipated to eat as a lot as 5 gigawatts of electrical energy. This summer time, Meta Chief Government Officer Mark Zuckerberg posted a graphic depicting Hyperion engulfing most of Manhattan – a picture that Trump later displayed at a White Home Cupboard assembly, saying the ability would value $50 billion.

To help the Meta web site, Entergy Corp. obtained regulatory approval in August to assemble three fuel vegetation able to producing about 2.3 gigawatts. Final month, along with these three vegetation, the utility utilized to tie new pure fuel technology to the grid in Louisiana to fulfill rising demand from knowledge facilities and industrial initiatives, together with from Meta and different hyperscalers.
“From the second that the Richland Parish knowledge middle got here onto the image, we’ve been planning for and executing to safe clear vitality to help that web site,” Urvi Parekh, Meta’s head of worldwide vitality, mentioned in an interview. “What we measure is what’s the carbon depth of the electrical energy that’s serving our knowledge middle after which working by way of the greenhouse fuel protocol guidelines.”
Meta additionally mentioned in an announcement that it plans so as to add sufficient clear and renewable vitality to match the full electrical energy use at Richland. To take action, the corporate mentioned it’s working with Entergy to convey 1.5 gigawatts of renewable vitality to the Louisiana grid and that it’s launched different clear and renewable vitality initiatives throughout the state, together with three targeted on photo voltaic.
Corporations like Meta usually purchase carbon offsets and renewable vitality certificates to steadiness the emissions tied to their operations, however each of these practices have been decried over time for various causes. Offsets could be notoriously troublesome to confirm, and renewable vitality certificates have been assailed for failing to realize actual emissions discount or drive renewable vitality technology.
Meta has maintained that almost all of its renewable vitality portfolio truly comes within the type of actual, long-term contracts akin to energy buy agreements and that “solely a small share” – lower than 5% of its reported renewable vitality purchases in 2023, for instance – have been tied to short-term, unbundled renewable vitality certificates.
Nuclear Possibility
Meta’s use of fuel to energy its new knowledge middle whereas nonetheless buying enormous quantities of fresh vitality displays a balancing act throughout the {industry}. Final month, Google introduced a first-of-its-kind settlement to purchase virtually the entire electrical energy from a fuel plant in Illinois whereas supplying the ability with carbon seize and storage gear.

The know-how will seize and retailer round 90% of the CO2 emissions from the plant, based on a Google release. However some skeptics have cautioned that emissions seize is neither economical nor possible at scale, and a nationwide carbon storage community would require as many as 96,000 miles of recent pipelines, based on Vitality Division estimates.
An alternative choice on the desk is nuclear vitality, which may present enormous quantities of round the clock energy, freed from carbon emissions. Google agreed final month to purchase nuclear energy from a plant that NextEra Vitality Inc. plans to restart in Iowa.
However nuclear energy can also be costly, and provide chain points imply that new nuclear vegetation will take years to construct and convey on-line. Although the NextEra generator is already constructed – and was solely shuttered in 2020 – the corporate received’t begin delivering energy to Google’s knowledge facilities till 2029.
To hyperlink knowledge facilities to energy sources sooner, US Vitality Secretary Chris Wright urged the Federal Vitality Regulatory Fee final month to expedite opinions for grid connections, based on paperwork reviewed by Bloomberg Information. As a part of a draft rule Wright despatched to the company, these opinions would shrink to 60 days, a seismic shift for a course of that at present can take years.
Beneath the proposal, knowledge facilities might win a speedy assessment in the event that they embody new energy vegetation or conform to curtail utilization in response to grid strains throughout high-demand durations akin to heatwaves. Nevertheless, an information middle vying to find subsequent to an present energy plant would require a research to find out if that technology capability is required to take care of grid reliability.
Trump Headwinds
Complicating issues is Trump, who has made the {industry}’s AI ambitions central to his second-term financial agenda. In September, he welcomed leaders, together with Nadella and Zuckerberg, for a White Home dinner the place he hailed tech firms’ far-reaching infrastructure spending plans and promised assist with allowing for vitality initiatives.
On the identical time, Trump has roiled the tech firms’ quest for electrical energy by attacking inexperienced vitality with a vengeance and assailing world warming as “the best con job ever” throughout a United Nations speech. The administration has stopped or delayed wind and photo voltaic initiatives – a few of which have been close to completion – and declined to ship delegates to the COP30 local weather convention in Brazil.
Certainly one of Trump’s greatest strikes in opposition to renewables was to make use of the large tax invoice he signed in July to strip away clear vitality incentives created by way of his predecessor Joe Biden’s Inflation Discount Act. Complete annual deployment of recent photo voltaic, wind and vitality storage services in 2035 can be 21% decrease – or 227 gigawatts much less – than it will have been with out the Trump tax legislation, based on BNEF forecasts.
Backing out of wind and photo voltaic initiatives as Trump envisions is problematic as a result of doing so would pressure firms to make use of different energy sources, like pure fuel, that aren’t essentially cheaper or sooner to get into service, mentioned Janous. He disputed the narrative that renewables can’t sufficiently energy knowledge facilities, arguing that the grid ought to be made extra versatile to raised use what photo voltaic and wind can supply.
Huge tech firms likewise can’t merely discard clear vitality commitments which have been a decade within the making for some companies, which have put money and time into reaching them, mentioned BNEF analyst Nayel Brihi.
“Dropping out now would initially damage their branding loads, but in addition would simply not make a number of enterprise sense for them due to on a regular basis and energy that’s been put in already,” he mentioned.
