A resilient home is a highly energy-efficient home that will maintain livable conditions even during power outages or interruptions in heating fuel.

When most people think about resilience--resilience to storms or terrorism, for example--they think only about resilience during the event. Equally important, if not more important, I believe, is resilience in the aftermath of that event. Hurricanes, ice storms, blizzards, wildfires, tornadoes, and other natural disasters not only have an immediate impact, for which we may or may not be able to prepare, but they often have a much longer-term impact, usually through extended power outages.
The same goes for terrorist actions; some suggest that smarter terrorists of the future may target our energy infrastructure or hack into power system controls to wreak havoc (cyberterrorism).
