Google’s 2024 Environmental Report, spanning over 80 pages, showcases the company’s efforts to address environmental issues and minimize its own environmental impact through the implementation of technology. However, one notable omission in the report is Google’s failure to address the significant energy consumption of AI technology. This omission suggests that the energy usage of AI may be alarmingly high.
This report details Google’s various initiatives, such as its water replenishment program, which aims to replenish the water used in its facilities and operations. By funding projects related to watershed restoration and irrigation management, Google has managed to replenish 18% of its water usage, with the goal of achieving a net positive result in the near future. It’s commendable that Google is taking steps to offset its water usage and contribute positively to the environment.
The report also highlights the potential benefits of AI in addressing climate change. Google emphasizes the ways in which AI can optimize watering systems, create more fuel-efficient routes for transportation, and predict natural disasters like floods. These applications of AI have promising implications for various sectors. It’s worth acknowledging that Google is going above and beyond by actively pursuing these initiatives, as many other companies of similar scale do not prioritize environmental efforts to this extent.
However, the report takes a surprising turn when it comes to addressing the energy consumption of AI. Google evades disclosing the actual energy usage of AI, which raises concerns about the magnitude of its impact. The report attempts to downplay the significance of energy usage in data centers by claiming that it only accounts for 1.3% of global energy consumption. In addition, Google states that its energy consumption is merely 10% of that figure, equating to a meager 0.1% of total global energy consumption. These statistics undermine the potential severity of the energy demands imposed by the use of AI.
Google’s 2021 commitment to achieving net-zero emissions by 2030 is mentioned in the report. However, the company admits to facing significant uncertainties regarding the execution of this goal, particularly due to the consistent increase in emissions since 2020. In 2023, Google’s total greenhouse gas emissions increased by 13% compared to the previous year, primarily driven by greater data center energy consumption and supply chain emissions. It is worth noting that the integration of AI into Google’s products may further exacerbate emissions due to increased energy demands stemming from AI computation and the anticipated growth of its technical infrastructure.
The report’s lack of transparency regarding the energy consumption of AI workloads within Google’s data centers is a cause for concern. Google resorts to vaguely acknowledging the complexities of predicting the future environmental impact of AI and dismisses the importance of distinguishing AI from other workloads. This evasive language implies that Google has comprehensive knowledge of the energy costs associated with AI training and inference, and its decision to withhold this information raises questions about its intentions.
It is implausible to believe that Google, a company well-versed in cloud computing and data center management, lacks the ability to precisely calculate the energy consumption of AI. The report includes statements about the efficiency of Google’s custom AI server units and its endeavors to reduce the energy required to train AI models. These statements suggest that Google has detailed insights into AI energy costs. As such, the absence of specific figures regarding AI’s energy consumption is puzzling.
While it is clear that Google is actively engaged in environmentally friendly initiatives, the report overlooks the significant and escalating energy demands of AI systems. Although Google may not be the primary contributor to global warming, it is pivotal to recognize that the company has not yet achieved a net positive environmental impact, despite the potential inherent in its operations.
Google has an incentive to downplay and obscure its AI energy usage figures, which are likely considerable even in its efficient state. Before the release of the 2025 report, it is important to request more specific details from Google regarding its AI energy consumption, as failing to do so may lead to further deterioration of the situation.
