What you should know about this indicator

  • This indicator shows what share of a country’s or region’s total electricity demand comes from data centers.
  • It covers total data-center electricity use (including cooling and other support systems), across both general-purpose and AI-specialized servers.
Share of total electricity demand coming from data centers
Data center electricity consumption as a share of total electricity demand of the country or region. Data centers power a wide range of online services beyond AI, such as streaming services and cloud storage. The data does not allow a separate estimate for AI use.

How we process data at Our World in Data

All data and visualizations on Our World in Data rely on data sourced from one or several original data providers. Preparing this original data involves several processing steps. Depending on the data, this can include standardizing country names and world region definitions, converting units, calculating derived indicators such as per capita measures, as well as adding or adapting metadata such as the name or the description given to an indicator.

At the link below you can find a detailed description of the structure of our data pipeline, including links to all the code used to prepare data across Our World in Data.

Notes on our processing step for this indicator

We calculated this share by dividing data center electricity consumption by total electricity demand for each country or region.
