CleanTechnica's Glenn Meyers offers a fresh look at Drake Landing Solar Community near Calgary, Alberta. The subdivision's district heating system, which combines garage-mounted solar panels with thermal storage, supplies more than 90 percent of the space heating needs of 52 single-family houses. An array of 144 boreholes 37 meters deep serves as an in-ground heat sink for seasonal storage.
"U.S. developers with renewable energy goals should look closely at the DLSC model," Meyers writes. "When calculating the energy savings, the large infrastructure costs can be offset over time. Potential homeowners may need convincing about future economic benefits that might be gained from being more independent from traditional utilities."
