I recently found this blog post from "gmoke," a local person and DailyKos blogger. He posted a PSA on solar energy that he had once shown on CCTV in 1991. Enjoy this Youtube installment of a retro PSA that is more relevant now than ever.
"This is one of a series of public service announcements produced for Boston Solar Energy Association at Cambridge Community TV in 1991. We took the PSAs around to the broadcast stations but only two were interested. I don't know if they ever got on the air but I used them on the shows I did for public access. In the 1970s, we'd produced another series of solar PSAs. At that time, the TV stations all took them but I saw them on the air only once on one station somewhere around two am although I heard from a few other people that they saw our "A south-facing window is a solar collector" and "A south-facing porch can become a sunspace or greenhouse" spots.
Thought I'd try again in these youtube days."
