Michigan's First Net Zero House uses Wattvision

Matt and Kelly Grocoff are some of our very first wattvision beta users.  Check out this awesome net zero house they've been working on for the last several years -- it now gives back as much power as it consumes from the grid, so it's a "net zero" house.  They've documented their work at Greenovation.TV, and if you jump to about 2:00 in the video below, you can see their wattvision setup!
