Alter Eco's Adrian Grenier by Stephanie Diani/Planet Green
As Entourage's Vince Chase, Adrian Grenier lives the glitzy life of a rising Hollywood ingenue, complete with SUVs and all. But the star will soon be guiding us toward a greener way of life with Alter Eco, a new series from Discovery's Planet Green.

During the 13-part series, Grenier, an "entourage" of three eco-experts and his curly locks will work with everyone from celebs to busy families to nightclub owners to help them find chic and easy ways to reduce their carbon footprints. With his trio, Grenier tours Los Angeles and offers viewers small ways they can green up their everyday lives.

Alter Eco's just one of a whole lineup of original shows the 'net has planned, most of which will be featuring celebs, such as the face-off show, Battleground Earth, featuring Ludacris and Tommy Lee (yes - Luda's reportedly going by the moniker "Luda the Polluta," while Lee's been dubbed "Toxic Tommy"). Will the celeb involvement help reach new demographics? Or will these mission-minded series stay buried amidst lighter summer fare? Planet Green launches in June. - Anna Dimond
