Large-scale Data Centers could potentially Revolutionize Worldwide Energy Consumption Patterns
The escalating number of data centers and the accelerated adoption of artificial intelligence (AI) could potentially cause subtle adjustments in global energy systems as we approach the latter part of this decade.
Previously, the computational requirements of most users were met by data centers consuming around 5MW of power per center. However, this is rapidly changing with an increase in large-scale or 'hyperscale' data centers, which typically consume over 100MW of power annually, equivalent to the electricity demand of around 350,000 to 400,000 electric cars, as per the International Energy Agency (IEA).
This is because a single query on a platform like ChatGPT requires 2.9Wh of electricity, while a standard Google search requires only 0.3Wh, approximately 10 times more.
Experts predict that the world will see a significant increase in hyperscale data centers due to AI's widespread use in everyday computing. For instance, Goldman Sachs estimates that the increase in data center power consumption due to AI could reach around 200TWh per year between 2023 and 2030.
A significant portion of the expansion of the hyperscale data center fleet is happening in the U.S., where the IEA believes construction has doubled in the past two years alone. Major economies like China and the European Union are also witnessing an increase in activity.
In 2023, the investment in AI and data center installation by tech giants like Google, Microsoft, and Amazon was higher than the entire U.S. oil and gas industry, amounting to approximately 0.5% of U.S. GDP.
An Altered Course of Global Power Consumption
This growth in AI and data centers is expected to "fundamentally alter" the course of global power consumption, according to S&P Global Commodity Insights. They anticipate that power demand for data centers will grow between 10% and 15% per year until 2030.
By 2030, data centers could account for up to 5% of total global power demand. In developed economies, data centers are contributing to a shift in growth from 2% to 3%. In developing economies, the additional data center demand will further boost electricity demand growth.
This enhanced growth poses a challenge to electricity grids, as new data center projects take about 2 to 3 years to complete, while new power supply can take 4 to 5 years, and transmission projects even longer.
Large tech companies have taken the lead in procuring clean energy to power their data centers. They have signed long-term power supply contracts with utilities and suppliers, with these contracts often relying on renewable energy sources like wind and solar power.
However, S&P Global Commodity Insights points out that this often diverts clean power away from the grid at large. It could potentially hinder carbon emissions reduction, as the increased demand might require additional gas-fired power generation capacity or even keep aging coal-fired generation capacities running longer than planned. This isn't the shift in energy systems many had envisioned for the turn of this decade.
- The rising prevalence of hyperscale data centers, driven by AI's integration into everyday computing, is predicted to augment the world's data center power consumption significantly.
- The International Energy Agency (IEA) reports that hyperscale data centers consume over 100MW of power annually, equivalent to the electricity demand of around 350,000 to 400,000 electric cars.
- To meet the computational demands of advanced technologies like AI, data centers are transitioning from consuming around 5MW of power per center to hyperscale data centers that require significantly more power, potentially impacting power grids.
- Experts estimate that the increase in data center power consumption due to AI could reach around 200TWh per year between 2023 and 2030, highlighting the growing impact of AI on global power consumption.
- In response to the increasing power demands of hyperscale data centers, major tech companies have entered into long-term power supply contracts with utilities and energy providers, often prioritizing renewable energy sources to mitigate environmental impact.
