The Green Button Data program in the US allows energy consumers to easily download their consumption data in a standard XML format. With that exported file, they can upload to a 3rd party site or app, who will provide a customized report.
My question: Are there any public data sets of real consumer green button data? For example, home-efficiency enthusiasts who have made their data public, either alone or as a group?
(I'll self-answer with some better know sample data sources)
