A premium home needs a fancy gas range, right? Wrong! An electric induction burner has the same power and quick response as a gas flame, but it uses energy more efficiently and won't demand (cold) makeup air as it gobbles up oxygen. And chefs love them!
Occupant behavior can make the difference between an efficient house and a wasteful one. Notorious energy hogs include plasma TVs, old refrigerators or freezers, ice-makers, and dehumidifiers. And don't overlook sneaky items like DVRs, always-on computer and entertainment equipment, etc.
