We have been happy customers of the energyfederation.org for years. They have a wide range of energy saving products from the most basic lightbulbs, to obscure items such as chimney balloons, to contractor products such as insulation.
We are happy to now be a part of their Affiliates Program. We recommend them for their great energy and water saving products, their great prices and their great information. Please share with us your experience with EFI, both positive and negative.
