AI data center expansion potentially undermines Big Tech's carbon neutral objectives
In the rapidly evolving world of technology, environmental campaigners are expressing concern over the growing reliance on data centers by tech companies, such as Meta and Microsoft, and the potential impact on their net-zero ambitions due to increased energy and water consumption.
The proliferation of data centers, housing the operations of tech giants like Apple, Amazon, Google, Meta, and Microsoft, has significantly increased in recent years, with the United States alone hosting over 5,400 data centers in 2021, compared to fewer than 1,500 in 2014. This expansion is not limited to quantity but also to size, with the average size and power usage of data centers operated by the world's biggest tech firms increasing significantly.
The energy demands of these tech companies' data centers are driving up electricity and water consumption, particularly in growing fields like artificial intelligence (AI) and cloud computing. Experts estimate that data centers will need an additional 18 gigawatts of power capacity by 2030 in the U.S. alone, comparable to three times New York City's entire power demand. In 2023, data centers accounted for about 4.4% of U.S. electricity consumption, a figure projected to nearly triple to 12% by 2028 if AI growth continues unabated.
Google, for instance, has seen its data center electricity use double from 14.4 million megawatt-hours in 2020 to 30.8 million megawatt-hours in 2024, driven almost entirely by data center demand. Other major players, like Apple, Amazon, Meta, and Microsoft, face similar pressures as their AI and cloud computing services expand, although specific detailed figures vary.
The enormous power consumption required to train and run AI models is driving up electricity demand significantly, potentially straining existing infrastructure. This could result in higher electricity bills for consumers and raise questions about who should bear the cost of the necessary energy infrastructure upgrades to support massive new data centers.
The energy mix is also in flux: while reliance on fossil fuels like natural gas and coal is expected to decline slightly or stabilize, renewables are expanding. However, it remains a challenge to supply clean energy at the pace data centers require. Public concern and regulatory scrutiny are increasing, with consumer and environmental advocacy groups pushing back against subsidies that support data center energy infrastructure without ensuring the tech companies contribute adequately.
The tech sector is facing a "climate strategy crisis," as the increasing energy demands of their data centers undermine the ambitious climate pledges these companies have made in recent years. The report from the NewClimate Institute suggests that these companies have lost focus on their climate strategies, with a shift from a proactive stance to uncertainty about meeting climate goals.

- As the tech industry's reliance on data centers escalates, concerns over their corporate responsibility towards climate change are growing, due to the increased consumption of carbon, energy, and water.
- Google, Apple, Amazon, Meta, and Microsoft, amongst others, are expanding their data centers at an alarming rate, with the US hosting over 5,400 in 2021, presenting a challenge for net-zero ambitions.
- Experts predict that data centers will demand an additional 18 gigawatts of power capacity by 2030 in the US alone, equivalent to three times New York City's entire power demand.
- The enormous power consumption of data centers could lead to strained infrastructure, potentially resulting in higher electricity bills, raising questions about who should bear the cost of necessary energy infrastructure upgrades.
- The tech sector's climate strategy is under scrutiny, as the increasing energy demands of data centers seem to undermine the ambitious climate pledges made by companies like Meta and Microsoft.
- The proliferation of green buildings and the development of clean energy sources are commendable efforts towards sustainability, but challenges remain in supplying clean energy at the pace data centers require.
- Advocacy groups are pushing for transparency and accountability, urging tech companies to contribute adequately to the cost of data center energy infrastructure, in line with the United Nations' Sustainable Development Goals (SDG) and the principles of environmental science.
