Renewable Redirect

Redirect edge requests to data centers favoring renewable energy and/or lower carbon intensity. World wide future carbon intensity estimations from the Carbon Aware API will be aggregated periodically by renewable report lambda to shared object store. The renewable report will also be available to browsers directly through cloudfront. Modern JavaScript applications can access this data and determine for themselves the best data center bypassing the edge redirect.

Renewable Report

The renewable report is written periodically contains limited data to make a favored lowest carbon intensity location determination quickly by applications ie. lambdas, clients, etc.
