We’ve been collecting data about how the web is powered since 2006 at the Green Web Foundation, and now have the largest dataset in the world of which sites use renewable power.
You can access this data in a number of ways.
Use the Green Web Check search on this site
You can check how any website on the internet is powered with the Green Web Check feature. Enter the url for the website, and you’ll get back the green status of the site, along with the evidence we based the decision on.
Using the browser extensions
You can download the Green Web Browser extensions, which can show you the green status of every site you visit, and every link on a page.
Use the API
If you want to automate checks like this, we also make this available using the Green Web API. You can test it in a browser, and building integrations is simple. If you need to host it yourself, the code for the API and the platform is open sourced under the Apache 2 license:
Downloading Green Web Data Direct
We want others to be able to use the Green Web data, to build new tools or services, carry out analysis, or do things we hadn’t thought of.
To support this, we make the bulk datasets available for free as open data under the Open Database Licence.
Got an idea for an app, or service? If you need help with integrating The Green Web Feed-API into your tool or website, get in touch via this support form, or drop us a line on twitter, at @greenwebfound. If you prefer chat, come say hi in our Zulip chat room.
