Microsoft is reconsidering its 2030 goal of ensuring all its data centers are powered via renewable, clean energy, as the financial and energy costs of building AI infrastructure strain climate commitments made before the current arms race began. The company’s internal discussions center on whether to delay or abandon its “100/100/0” target, an initiative announced in 2021 that pledged to match 100% of its electricity consumption, 100% of the time, with zero-carbon energy in a bid to fully rely on renewable energy for its data centers.No final decision has been made by the company; however, it is no surprise that this is being considered, as the costs of AI services have continued to ramp up in the last year. Why Microsoft could abandon its pledge The tension is straightforward: Microsoft , Amazon, and Alphabet are collectively spending hundreds of billions of dollars to build more data center capacity for AI services. Some of those facilities are expected to consume multiple gigawatts of power, with a single gigawatt sufficient to power approximately 750,000 U.S. homes .Microsoft has been adding approximately one gigawatt of data center capacity every three months. That pace makes the proposed hour-by-hour renewable matching far more expensive and logistically difficult than the annual matching target the company already meets. The hourly commitment was always considered a stretch internally, according to people familiar with the program.Carbon emissions across the sector are moving in the wrong direction. In their most recent sustainability reports, Meta, Alphabet’s Google, Amazon, and Microsoft disclosed emissions increases of 64%, 51%, and similarly steep figures .“In the race to get data centres up and running as soon as possible, clean energy targets are out of the window,” said Alexia Kelly, former director of net zero and nature at Netflix and now managing director of the carbon policy and markets initiative at High Tide Foundation, “Gas seems to be the fuel of choice.” Why natural gas reigns supreme The growing reliance on natural gas to power AI infrastructure represents a direct trade-off against climate targets. Industry executives have argued that gas is faster and easier to deploy than renewables .Microsoft has pursued nuclear energy as one alternative, agreeing in 2024 to a power deal with Constellation Energy to help restart a unit of the Three Mile Island nuclear plant in Pennsylvania. But nuclear projects operate on long timelines, and the demand for AI compute is accelerating significantly in the present.Microsoft continues to invest in data center expansion globally. In April, the company announced a set-aside $329 million for cloud infrastructure and AI capabilities in South Africa, including improvements in energy and water readiness. The contrast between these ongoing investments and the potential backsliding on commitments to clean, renewable energy points to a priority shift across the tech sector: ensuring power supply first, before worrying about its source. Kenya Microsoft project suspension signals real-world limits The energy strain from AI services is not theoretical. Kenya suspended a $1 billion data center project backed by Microsoft and UAE-based G42 after President William Ruto determined the country lacked sufficient power capacity to support it .Kenya’s installed electricity capacity sits at roughly 3,000 megawatts. The proposed facility, planned for a site about 100 kilometers northwest of Nairobi, would have required approximately a third of that supply. “To switch on that one data centre, we would need to shut off power for half the country. That’s when I knew there was a problem,” Ruto said.The project, first announced during Ruto’s state visit to Washington in May 2024, was intended to run largely on geothermal energy and deliver Azure cloud services to businesses and government institutions. A concept note prepared by Kenya’s technology ministry failed to receive funding clearance from the National Treasury, effectively halting progress. By August 2025, more unfruitful meetings between Kenyan officials and Microsoft executives signaled the project would miss its original May 2026 completion date.
