Affordable 'green homes' being built in Frederick
Each house will have about 20 solar panels, which will generate more electricity than the house uses during the day. The excess electricity will go to the grid and be credited to the home; the residents can essentially cash in that credit at night when they use more power. The homes should have net-zero energy usage.
This is a great new development (in more ways than one) and I hope we see more of them in the DC region!
