The Energy Quandary of Tech Giants
The ambition of Amazon, Google, and Microsoft to accelerate their “speed to power” initiatives—bolstered by an astounding combined investment of approximately $750 billion in data center expansion in the years 2025 and 2026—is significantly jeopardizing their climate commitments.
In their 2025 environmental sustainability updates, all three tech behemoths reported alarming double-digit increases in emissions.
This surge can largely be attributed to electricity usage: Amazon and Google saw reported emissions linked to power consumption soar by over one-third, while Microsoft experienced an increase in excess of 20 percent.
Insatiable Power Appetites
Google’s electricity consumption surged an unprecedented 37 percent in 2025, reaching 43.6 million megawatt-hours—the most significant single-year increase in its illustrious history, sufficient to power the entire state of Washington for a year.
“The rapid advancement of AI is amplifying our energy requirements, and the transition to clean energy is encountering substantial roadblocks—such as prolonged delays in connecting new energy projects to the grid, fragmented power grids, and an acute shortage of reliable, continuous clean power,” observed Google in its 2025 environmental report, released on June 30.
Since 2019, Google’s energy consumption has surged by 250 percent. Its location-based electricity emissions, classified under Scope 2 of the Greenhouse Gas Protocol’s carbon accounting standards, escalated by 37 percent from 2024 to 2025.
Location-based emissions are assessed using regional grid market averages; in contrast, market-based emissions encompass factors such as green tariffs and renewable energy certificates.
Microsoft also reported a 21 percent uptick in location-based Scope 2 emissions, along with a 24 percent increase in overall electricity consumption, reaching 37 million megawatt-hours.
In Amazon’s 2025 environmental report, published on July 1, the company refrained from disclosing its total electricity consumption. It did, however, note a 34 percent rise in Scope 2 emissions, without clarifying whether this figure is location-based or market-based.
Additionally, Amazon did not delineate emissions specifically attributable to Amazon Web Services. However, it does provide various metrics, including power usage effectiveness, which assesses the energy a data center employs for cooling relative to operational computing equipment. The closer this figure is to zero, the better.
Amazon’s average effectiveness across its data center portfolio stands at 1.14, while Google maintains a ratio of 1.09 and Microsoft a score of 1.17.
What to Watch Next
Despite their burgeoning energy demands, Amazon, Google, and Microsoft remain steadfast in their emissions reduction commitments aimed at 2030 and beyond.
Why is this the case? Over the past decade, these giants have inked contracts totaling more than 115 gigawatts of renewable energy—predominantly sourced from solar and wind—into the global electric grid.
The companies are also eyeing investments in the nuclear energy sector as a cornerstone of their strategy. Amazon secured nearly 2 gigawatts of nuclear power last June and has subsequently signed agreements for two new nuclear ventures slated for 2026.
Microsoft is investing in various next-generation fusion technologies, while Google has committed to capacity within Ohio. In contrast, Meta has demonstrated unparalleled eagerness with agreements for up to 7.7 gigawatts.
Moreover, significant investments in large-scale battery technologies will be pivotal. By the end of 2025, Amazon had 15 solar energy projects integrated with energy storage, boasting a cumulative capacity of approximately 2.3 gigawatts.
Google is making considerable investments in long-duration battery solutions to maximize the benefits of their solar and wind contracts—an objective also prioritized by Meta.
Anticipate a heightened emphasis on initiatives in Asia. Amazon is currently involved in roughly 2.2 gigawatts of clean energy projects within the Asia-Pacific region, albeit still largely dependent on fossil fuels.
For context, the firm’s global energy portfolio hovers around 40 gigawatts. Google has explicitly identified Asia as a critical area for “carbon-free” electricity purchases, although it signed contracts last year in Malaysia and Japan.
Meanwhile, Microsoft is financing the Southeast Asia Clean Energy Facility, which has so far allocated $230 million into nascent projects.
