Green living enthusiasts can learn about eco-friendly building practices and sustainable living alternatives from the convenience of their laptop, video iPod or iPhone, thanks to a new digital TV show, Mainstream Green, from ON Networks. The video-on-demand series is designed to be an online green resource for consumers buying or building a home, as well as existing home owners looking to “go green.”

Hosted by high-performance home builder Alex Pettitt, Mainstream Green engages and informs viewers on all things environmentally friendly – from the nitty-gritty of insulation to the big picture of master-planned communities. By educating viewers on such eco-friendly building alternatives, Mainstream Green hopes to arm them with money-saving, healthier options that are also designed to make the world a little greener.

Part documentary, part interview show and part “how to,” Mainstream Green’s format is much like that of an HGTV program, with a dash of This Old House thrown in. Each 4-6 minute episode tackles a different topic, ranging from recycling on the job to eco-friendly pest management.

Mainstream Green is part of ON Networks’ collection of smart entertainment that can be watched anytime, anywhere and on any device. ON Networks is one of the largest providers of original, high-definition content that is compatible with all Apple platforms, including the iPhone, iPod and Apple TV.
