AI-driven data centers and rising energy demand
Why does AI need data centers?
Artificial Intelligence requires massive computing power to process complex algorithms and vast datasets. Data centers provide the essential infrastructure for AI operations, offering the high-performance computing capabilities needed for training and inference workloads. Modern AI models demand 10 times more resources than traditional cloud applications, requiring specialized facilities with sufficient power, cooling, and redundancy to handle these intensive workloads.
How much energy does AI use?
AI's energy appetite is substantial and growing rapidly. According to Deloitte, data centers will consume approximately 536 TWh of electricity in 2025, representing about 2% of global electricity consumption. This figure could double to 1,065 TWh by 2030 as AI computing power requirements continue to escalate. Training a single large AI model can consume energy equivalent to hundreds of households over several months, while even routine inference operations significantly increase power demands compared to traditional computing tasks.
AI energy problem: will power demand outstrip supply?
The surging power requirements for AI computing present a critical challenge for energy infrastructure. McKinsey research indicates that AI data centers could consume 11-12% of the United States' total electricity by 2030, potentially creating supply deficits in many regions.

Water usage in data centers: cooling challenges and solutions
How much water do AI data centers use?
AI data centers consume staggering amounts of water primarily for cooling their heat-generating server equipment. According to recent studies from Stanford University and Lawrence Berkeley National Laboratory, data centers in the United States consumed approximately 17.5 billion gallons of water in 2023, representing about 0.3% of the total public water supply. The scale varies dramatically by facility size—a typical large data center can consume up to 5 million gallons of water daily, equivalent to the water needs of a town with 10,000 to 50,000 residents. Google's global data center operations alone used approximately 5.2 billion gallons annually, while Meta's facilities consumed 663 million gallons, with the average Google data center requiring about 550,000 gallons daily.
Data center water usage and environmental impact
The environmental footprint of data center water consumption extends far beyond simple volume metrics. Data centers typically evaporate about 80% of the water they draw, compared to just 10% for residential usage, making them particularly intensive on local water resources. This has created significant challenges for utilities and communities, especially in water-stressed regions where approximately two-thirds of new data centers have been built since 2022. In Phoenix alone, nearly 60 data centers collectively consume about 177 million gallons of water daily. To mitigate these impacts, forward-thinking operators are implementing solutions mentioned earlier in our discussion of green initiatives, including recycled-water systems where data centers partner with local utilities to use treated sewage instead of drinking water, and adiabatic cooling technologies that significantly reduce overall water requirements.
Calculating and benchmarking data center power consumption
How to calculate data center power consumption?
Data center power consumption can be calculated using the formula: Total Power (kW) = Server Power (W) × Number of Servers ÷ 1,000. This provides the baseline IT power requirements. For comprehensive metrics, measure both IT equipment power and facility overhead (cooling, lighting, security systems). Advanced monitoring systems like DIRIS Digiware can track these metrics in real-time, providing accurate consumption data for optimization decisions.
Power Usage Effectiveness (PUE) and other metrics
Power Usage Effectiveness (PUE), standardized under ISO/IEC 30134-2:2016, is the most widely used efficiency metric calculated by dividing total facility energy by IT equipment energy. A perfect PUE of 1.0 indicates 100% efficiency. Beyond PUE, modern data centers track additional metrics like IT Equipment Utilization Effectiveness (ITUE), Cooling Efficiency Ratio (CER), and cabinet-level power density (kW/rack) to comprehensively evaluate performance.
