I have found that rating and certification agencies for green and renewable energy products are subject to political and industry pressure and that their online reports make it very difficult to sort out which products merely qualify from those that are truly outstanding in their performance. However, if you are willing to dig through the data you can find the products that stand out from those that just provide the minimum amount of performance to make the approved list. As I continue to dig through the various certification documents, I’ll post the results on this page as downloadable PDF documents.
