The rapid expansion of Big Tech’s data centers has led to significant public health costs totaling over $5.4 billion in the last five years. This revelation sheds light on the profound impact of constructing infrastructure to support artificial intelligence systems. Studies conducted by UC Riverside and Caltech have linked the air pollution resulting from the immense energy consumption of data centers to the treatment of various health issues, including cancer and asthma.
Key points:
- Research estimates suggest that treating illnesses related to data center pollution cost $1.5 billion in 2023, marking a 20% increase from the previous year.
- The cumulative cost of health-related issues stemming from air pollution since 2019 is reported to be $5.4 billion.
- The boom in generative AI development has driven major tech companies like Microsoft, Alphabet, Amazon, and Meta to predict AI spending to surpass $320 billion in the current year, a significant jump from $151 billion in 2023.
- Recently, OpenAI and SoftBank announced a joint venture called “Stargate” that plans to invest a massive $500 billion in AI infrastructure in the US.
The analysis conducted by UC Riverside and Caltech utilized a reputable modeling tool from the US Environmental Protection Agency to translate air quality and health impacts into economic terms. According to their findings, Google incurred the highest health costs of $2.6 billion over the five-year period from 2019 to 2023, followed by Microsoft at $1.6 billion and Meta at $1.2 billion. The health costs associated with each company increased annually.
Data centers contribute to pollution primarily through their substantial electricity consumption, often sourced from fossil fuels. Additionally, the use of backup generators powered by diesel can worsen air quality, and the disposal of hardware waste can release harmful chemicals into the environment.
Despite some companies purchasing renewable energy certificates to offset their electricity consumption’s pollution, the research focused on the pollution directly generated in the areas where data centers operate. This localized accounting approach does not allow for emissions in one location to be offset by cleaner air elsewhere.
Both Google, Meta, and Microsoft clarified that their use of backup generators fell below the levels estimated in the research. However, Google emphasized that the health cost estimates were overstated due to the omission of clean energy purchases in local markets. Microsoft and Meta reiterated their commitment to environmental sustainability and community support.
Concluding thoughts:
The location of data centers in regions like West Virginia and Ohio disproportionately impacts lower-income households, intensifying public health risks. With tech giants strategically placing data centers in less populated areas, the trend of escalating public health threats could potentially be reversed.
Data centers play a critical role in powering AI technologies, but their energy-intensive operations pose significant challenges to air quality and public health. It is imperative for the tech industry to address these concerns and prioritize sustainable practices to mitigate the adverse effects on communities and the environment.
