The world is on the brink of a significant transformation in energy consumption, driven by the escalating demands of data centers. On average, a ChatGPT query requires nearly ten times the electricity of a Google search. This difference highlights the upcoming changes in power consumption patterns in the US, Europe, and globally, and the associated costs.
The Stable Past of Data Center Energy Consumption
For years, data centers maintained a relatively stable appetite for power despite increasing workloads. Between 2015 and 2019, data center workloads nearly tripled, yet their power demand remained around 200 terawatt-hours annually. This stability was attributed to continuous efficiency improvements in power usage. However, since 2020, these efficiency gains have plateaued, and power consumption by data centers has started to rise.
Projected Surge in Power Demand
Goldman Sachs Research estimates that data center power demand will grow by 160% by 2030. Currently, data centers consume 1-2% of global power, but this is expected to rise to 3-4% by the end of the decade. In the US and Europe, this surge will drive electricity growth unseen in a generation, potentially doubling carbon dioxide emissions from data centers between 2022 and 2030.
The Impact of AI on Power Consumption
AI innovations, while boosting computing speed, will also significantly increase power consumption. A single ChatGPT query requires 2.9 watt-hours of electricity compared to 0.3 watt-hours for a Google search. Goldman Sachs Research projects an additional 200 terawatt-hours per year in data center power consumption from AI by 2030. By 2028, AI is expected to account for about 19% of data center power demand.
Environmental and Economic Implications
The rise in data center carbon dioxide emissions will represent a “social cost” of $125-140 billion (at present value). While technology companies remain confident in reducing energy intensity, meeting absolute emissions targets is challenging due to rising demand. Substantial investments in renewable energy and emerging nuclear generation capabilities are anticipated to address these challenges. Additionally, AI could drive innovations in various sectors, including healthcare, agriculture, and energy efficiency, potentially offsetting some of its environmental impact.
Power Demand Growth in the US
Over the past decade, US power demand growth has been negligible, despite increases in population and economic activity. Efficiency measures, such as LED lighting, have helped maintain this balance. However, between 2022 and 2030, power demand is expected to rise by 2.4%, with data centers accounting for 0.9 percentage points of this increase. By 2030, data centers will consume 8% of US power, up from 3% in 2022.
To support this demand, US utilities will need to invest around $50 billion in new generation capacity. Additionally, data center power consumption will drive approximately 3.3 billion cubic feet per day of new natural gas demand by 2030, necessitating new pipeline capacity.
The European Perspective
Europe’s power demand has been impacted by various shocks over the past 15 years, including the global financial crisis, the COVID-19 pandemic, and the energy crisis triggered by the war in Ukraine. Furthermore, slower-than-expected electrification and ongoing de-industrialization have led to a cumulative decline in electricity demand by nearly 10% since its 2008 peak.
Looking ahead, Goldman Sachs Research projects a 40-50% increase in Europe’s power demand between 2023 and 2033, driven by the expansion of data centers and accelerated electrification. Currently, 15% of the world’s data centers are in Europe, and by 2030, their power needs will match the current total consumption of Portugal, Greece, and the Netherlands combined.
Investment in European Power Infrastructure
Data center power demand will rise in two types of European countries: those with abundant renewable energy sources and those with large financial and tech sectors offering incentives for data centers. Nations like the Nordics, Spain, and France fall into the first category, while Germany, the UK, and Ireland represent the second.
Europe, with its aging power grid, will require significant investments to support new data centers. Goldman Sachs analysts anticipate nearly €800 billion ($861 billion) in spending on transmission and distribution over the next decade, along with €850 billion on solar, onshore wind, and offshore wind energy.
Looking Ahead
The rising power demands of data centers signify a new era of energy consumption. While challenges lie ahead, particularly in managing carbon emissions and investing in infrastructure, the potential for innovation and growth is substantial. As the world adapts to these changes, the balance between technological advancement and environmental responsibility will be crucial in shaping our future energy landscape.
