Glass Buildings In Helsinki (where I'm going this week, image by gadl, CC 2.0 licensed)

I have been discovering and joining a few interesting online communities focused on energy and sustainability issues. While it's hard to keep up on everything that's going on, they seem like a good source of like-minded folks with whom to discuss your ideas.

• One of these is the Energy Collective. One of their features is that they aggregate selected posts from a number of blogs in the green energy space. The posts selected are usually meaty, and there are typically quite a few comments on each post through the Energy Collective.
• Another good source of green energy and sustainability groups is  LinkedIn. I have a group there, the Green Building/Green Energy Salon, which I welcome you to join. Other green and sustainability-related groups include the Clean Energy Community, Green & Sustainability Innovators & Innovation Network, Green, and my friend Rich Wingerter's Green Making Home Construction Professional Group.

I'll post about some other communities in the future.

BTW, I'm traveling to Finland for the week today. Posts might be coming a bit less frequently until next week, depending on my schedule of meetings when I get there.
