Please take the time to decide on the sub-category which best fits your product or service.

This category tree is for commercial and business sites specializing in energy generation from sources that can be replaced, with emphasis on those that do not increase carbon in the atmosphere.  Sites will rarely be listed at the top, so please suggest your site to the sub-category that represents 80% or more of the business, whether manufacturers, distributors, retailers, installers, consultants, and production equipment manufacturers for any of the associated industries.

Installers, please note:

This category tree is for web sites that serve multi-state or worldwide operations. If the web site offers installation services that use products manufactured from other sources, and are not offered beyond the country border, then it will not be listed here.
Such sites are best suggested to the most specific category available in the Regional tree.  If the site only shows one office location, then please suggest it to that locality's Business and Economy cateory.  If the site is not specifically geared towards this tree, please suggest it to the most appropriate category, since suggesting to the wrong category will delay and/or prevent your site from being listed in the directory.

Suggestion Tips:

1. When writing the site's title please ensure it is the same as the organization.
2. When writing the site's description, please state what your site offers in a clear and concise statement without hype or promotional language.
