I'm determined to put solar panels on the next home that Chris and I purchase. Don't worry, I'm not going to get all Green and Preachy about it, but check out this adorable Berkeley cottage and see if you're not inspired. It's small - that's for sure, but sometimes less is more. That's not to say that this place was cheap to build, it probably cost a minor fortune. But $6 gas and electric bills are a dream come true!
