Vote Solar. Bringing solar energy into the mainstream.
Vote Solar is a solar advocacy group based in San Francisco that is bolstering and facilitating solar energy projects from a process and policy perspective - on a federal, state, local (ie. cities), AND community level.
You can get involved by joining the email sign-up and they will send (just enough, not too much) info about big news, local events, or opportunities to participate and make a difference on key solar issues.
Moreover, Vote Solar has an excellent set of solar resources, and they are launching a free weekly webinar series called Get Some Sun. The next webinar is on Wednesday, September 21st:
"Midterm PV Progress Report"
An assessment on the current state of the industry, updates on international PV markets, and prognostications on what it all means for 2012 -- with Paula Mints of Navigant Consulting.
I signed up already. And you should too!
