Microsoft's AI data center expansion threatens ambitious clean energy goals by 2030

Microsoft's AI data center push is colliding with its clean power goals | TechCrunch

Microsoft is weighing whether to delay or scale back one of its most ambitious clean energy goals as its rapid buildout of AI data centers puts pressure on its ability to meet those targets. Microsoft has yet to make any public announcements, but according to Bloomberg the company is having internal discussions over its hourly clean energy matching goal. The tech company has said that by 2030 it intends to match 100% of its hourly energy use with clean power on the same grid. But Microsoft's rush to build AI data centers has apparently sparked debate within the company about whether the pledge has become an impediment to its ambitions. Microsoft declined to comment on the internal debate over the hourly matching goal. Instead, a spokesperson told TechCrunch the company continues "to look for opportunities to maintain our annual matching goal." Hourly targets like the kind Microsoft has set for itself are more rigorous than annual targets. Because the grid is a balanced system -- the supply and demand of electrons needs to be matched on a near-instantaneous basis -- hourly matching helps develop clean energy sources that more closely align with a company's usage patterns. Annual targets are more lenient. They are effectively accounting tricks that could, for example, let a company buy more solar power than it might use at midday. Other customers on the grid use that energy, but the company that paid for the solar panels gets to claim the renewable power they make. It's a tidy arrangement that has sped the deployment of wind, solar, and batteries. But on its own, annual targets won't eliminate fossil fuels entirely. Hourly targets help foster renewable development that more closely mimics how a true net-zero world would be powered. Big tech companies like Microsoft, Meta, Google, and Apple have generally led on emissions reductions, setting aggressive net-zero targets. Many have eliminated their carbon emissions on an annual basis. Microsoft, for instance, said it met that goal last year. But as data centers grow in size and number, those same companies are turning to natural gas. Microsoft is included in that list; last month, the company said it was working with Chevron and Engine No. 1 to build a massive natural gas power plant in West Texas that could eventually generate up to 5 gigawatts. Despite the West Texas project, Microsoft is widely viewed as a leader among tech companies pursuing net zero emissions. By 2030, Microsoft intends to remove more carbon from the atmosphere than its operations produce. Part of the company's renewable push has been driven by an internal carbon tax. The Microsoft spokesperson did not reply to questions about the company's carbon tax. If it remains in place, some of the internal debate surrounding hourly matching might revolve around a cost-benefit analysis of the shift. If Microsoft were to abandon its hourly-matching target, the company would also lose some leverage in efforts to sell the public on its on its data centers. As data centers have proliferated, the general public has begun to push back against them, citing concerns over pollution, power prices, and water use. When Microsoft brings its own clean power to a project, it can plausibly say it has addressed two of those concerns. Without it, new data centers might be harder to sell to the public.

Microsoft may shelve 2030 clean energy target as AI lifts power use, Bloomberg News reports

May 6 (Reuters) - Microsoft (MSFT.O), opens new tab is considering delaying or abandoning its 2030 goal of matching its entire hourly electricity use with renewable energy purchases, Bloomberg News reported on Wednesday, citing people familiar with the matter. The expensive and energy-intensive push for data centers is reshaping the feasibility of Microsoft's climate commitments that were made before the AI era and rank among the industry's most ambitious ⁠targets, the report said. The discussions were ongoing and no final decision has been made, Bloomberg News added. Microsoft did not immediately respond to a Reuters request for comment. Like rivals Amazon (AMZN.O), opens new tab and Alphabet (GOOGL.O), opens new tab, the Windows maker is spending hundreds of billions of dollars to build out artificial intelligence infrastructure needed to power services such as its Copilot assistant and Azure cloud ⁠service. Some of the new data centers tech companies are developing are expected to have multiple gigawatts of capacity. A single gigawatt is enough to roughly power 750,000 U.S. homes. The rush to ⁠power those data centers has sparked a flurry of deals, including those for nuclear energy. It has also boosted demand for natural gas, ⁠which some industry executives have said is faster and easier to deploy than renewables. Microsoft in 2024 agreed a power ⁠deal with Constellation Energy (CEG.O), opens new tab to help resurrect a unit of the Three Mile Island nuclear plant in Pennsylvania.

Report: As AI electricity demands soar, Microsoft weighs retreat from ambitious carbon-free energy pledge

Microsoft is considering scaling down or scuttling a pledge to match its electricity use with carbon-free power around the clock by 2030, according to Bloomberg. As tech companies race to bring more energy-hungry data centers online, their climate targets are growing increasingly difficult to hit. Microsoft has been a vocal leader in climate action, setting ambitious emissions goals and backing carbon-reducing technologies -- but that momentum appears to be softening on multiple fronts. Last month, the New York Times reported that the Redmond, Wash.-based company was pausing its future purchases of carbon removal credits, though company leadership said the program wasn't ending. Microsoft has been the driving force in that industry, which includes startups that pull carbon from the air or capture it from industrial emissions, nature-based solutions for storing or trapping carbon in soil or rocks. And following years of announcements celebrating new renewable energy projects, Bloomberg reported in March that Microsoft was in "exclusive talks" with Chevron and Engine No. 1 to develop a gas-powered plant in Texas that would generate electricity for a data center campus. The company is standing by its sustainability targets. "Microsoft remains committed to its company goals to be carbon negative, water positive, zero waste, and protect ecosystems. In 2025, we met a milestone on this journey by matching 100% of our annual global electricity consumption with renewable energy," said Melanie Nakagawa, Microsoft's chief sustainability officer, in an emailed statement. Microsoft and cross-town rival Amazon have both hit the goal of matching their total energy use with purchases of an equal quantity of clean power. But in 2021, Microsoft raised the bar by committing to round-the-clock renewable energy use -- a harder target to hit given that sources like wind and solar aren't always available. The company even teamed up with Seattle startup LevelTen Energy, Google, and two clean energy companies in 2023 to create a marketplace for organizations pursuing all renewable power 24/7. Nakagawa said that Microsoft continually reviews and adjusts its climate approach "as markets mature, policy environments evolve, and emerging innovative solutions scale," adding that "any adjustments we make are part of our disciplined approach -- not a change in our long-term ambition." Those ambitions keep getting harder to reach. Microsoft CFO Amy Hood said last month that capital expenditures -- which largely fund data centers and hardware -- would exceed $40 billion in the current quarter, setting a new record. Total capital spending is expected to hit $190 billion this year. The computing facilities are the top contributor to Microsoft's expanding carbon footprint driven by their energy demands and the carbon-intensive steel and concrete required to build them. Microsoft's carbon impact grew 23.4% from 2020 to 2024, even as the company is still targeting net zero emissions by the end of the decade. Despite those challenges, Microsoft is still signing clean energy deals. It recently agreed to deploy 1.2 gigawatts of solar and battery projects in Wisconsin with We Energies -- roughly half of Seattle City Light's total generation capacity. The energy is expected to come online in December 2028, a company spokesperson said.

Microsoft, looking to build data centers, considers dumping climate goal, report states

Microsoft stands out as one of the most environmentally responsible companies in Big Tech, but a new report indicates it may be retreating from one of its most ambitious climate goals. The Redmond, Washington-based company previously pledged to match 100 percent of its hourly electricity use with renewable energy purchases by 2030; Microsoft already meets its annual targets for renewable energy matches. Now, with pressure to construct data centers to fuel AI, Microsoft is considering delaying or abandoning that hourly goal, Bloomberg reports. The hourly clean power goal is named 100/100/0, indicating the intent to match all of its energy use, all of the time, with zero-carbon energy purchases. That goal is complicated by the enormous amount Microsoft is spending on data centers, around $190 billion through the end of the year. The data center boom has equated to less money for other corporate endeavors, like clean energy. In the wake of those costs, Microsoft has already begun reducing its carbon-dioxide removal program. Many tech companies are looking to natural gas -- which emits Earth-warming greenhouse gases -- to partially power their data centers, rather than cleaner energy sources like solar, wind, or hydro power. The companies of Big Tech are all emitting more carbon in the wake of the AI race; Microsoft has seen a 23 percent jump in carbon emissions since late 2022, while Google's increased by 51 percent and Meta's by 64 percent during that same time period, Bloomberg reports.
