'Mainstream Green' = 'This Old House' + green

A new digital television show has surfaced promoting ideas for going green in matters related to building practices and sustainable living. It's called Mainstream Green and it's appearing for free via online media company ON Networks.

Mainstream Green, designed to be viewable on a computer or iPod/iPhone or through a television connected to an Apple TV, promotes green building ideas for new and existing home owners.

It's hosted by a "high-performance" home builder by the name of Alex Pettit, who talks about everything insulation to master-planned communities. The show, which airs in four- to six-minute episodes, is described by ON Networks as part HGTV, part This Old House.

The show will attempt to balance going green with saving money and living more healthy. Episodes already posted cover topics of insulation and integrated pest management.
