My guess at the top 3 priorities for moving forward toward our big, hairy, audacious goal:

#1 - Populate the site with useful links and information.
#2 - Establish a matrix of "The best clean, sustainable energy solution for a home or small business available at the moment" reference designs for a few common scenarios.
#3 - Establish a project page for improving each of the reference designs, and get people leading each effort.
