The Green Entrepreneur’s Toolbox: 100 Networking Resources, Guides, and Links over at Bootstrapper is a nice resource for a starting entrepreneur or an experienced one looking to go sustainable.

The 100 resources nicely broken down into seven sections

1. Blogs and publications — these cover a broad range from clean technology to corporate social responsiblity.
2. Success stories — always nice to know that their is light at the end of the entrepreneurial tunnel.
3. Tools — primarily focused on business tools, but they bring up a good point, a green business probably wants to be as paperless as possible.  Its about showing a green ethos through and through.
4. Guides and education — includes a lot of links to various evironmental standards and guides to green MBA programs.  Many but not all of these resources will show up on my Resources page as well. 
5. Networking and organizations — you are not alone.  There are also some good places to advertise your green business or product.
6. Assistance — a nice list of places to look for investment or grants to get your business up, running or growing.
7. Books — a nice list of books to check out of the local library.

Insight — When I first looked at the list I wondered why the tools section contained general business tools.  Then it struck me — not everyone has started a business before, and may not be familiar with these types of tools.  But the real insight was about where to look for new business ideas — in ideas or experiences that you take for granted.  When you get heads down in your area of expertise or are really passionate about something it is easy to forget that not everyone shares your knowledge.  So what might see old to you might be totally new to the wider market place.
