Green Web Datasets

Since 2006, we have been building the world’s largest database tracking which parts of the internet run on renewable power, and when they switched.

You can check the current state of this information with the Green Web API, but we make this underlying data available for download in bulk, for your analysis.

Using this database

We make these datasets available below, free of charge, with a permissive licence, to encourage the development of tooling and products using them.

We make this available under the Open Database Licence:

You are free:

  • To Share: To copy, distribute and use the database.
  • To Create: To produce works from the database.
  • To Adapt: To modify, transform and build upon the database.

As long as you:

  • Attribute: You must attribute any public use of the database, or works produced from the database, in the manner specified in the ODbL. For any use or redistribution of the database, or works produced from it, you must make clear to others the license of the database and keep intact any notices on the original database.
  • Share-Alike: If you publicly use any adapted version of this database, or works produced from an adapted database, you must also offer that adapted database under the ODbL.
  • Keep open: If you redistribute the database, or an adapted version of it, then you may use technological measures that restrict the work (such as DRM) as long as you also redistribute a version without such measures.

Our datasets

This dataset is based on the same list of the top million domains as used by the HTTP Archive, for their monthly reports.
