The Department of Energy today backed a deal to connect solar electric panels at 160,000 locations on military bases, a move which could double the number of residential solar installations in the U.S.

The DOE said it has provided a conditional commitment to guarantee a $344 million loan for the SolarStrong Project, which will help the military meet its renewable energy targets and bring solar power to a many states which now have little.

Sonnenschiff Solar City Produces 4X the Energy it Consumes

Although net-zero projects have been creating a lot of buzz lately in the field of green building, the Sonnenschiff solar city in Freiburg, Germany is very much net positive. The self-sustaining city accomplishes this feat through smart solar design and lots and lots of photovoltaic panels pointed in the right direction. It seems like a simple strategy — but designers often incorporate solar installations as an afterthought, or worse, as a label. Designed by Rolf Disch, the Sonnenschiff (Solar Ship) and Solarsiedlung (Solar Village) emphasize power production from the start by smartly incorporating a series of large rooftop solar arrays that double as sun shades. The buildings are also built to Passivhaus standards, which allows the project to produce four times the amount of energy it consumes!
