Austin Energy Green Building holds a Green by Design workshop four times a year - I attended in February and I loved it! If you're thinking about building green this workshop is a great place to start.
When I attended the workshop I learned about Eco-Wise. Recently I had a friend ask me about a source for environmentally friendly kitchen & bath countertops. Eco-Wise instantly came to mind!
