I just made live a directory for renewable energy companies and websites. The directory is completely free, but does have a featured link option, which for $24.99 makes you a featured link for life. If you have a renewal energy or green site/blog please visit http://www.renewable-energy-links.com.
Interresting. Good idea to list sites with such content. Hope this directory will have a long life and more sites added for some good infos.
