Which measure is listed as a cost-effective option to reduce fuel costs?

• A. install baseboard heaters
• B. replace windows
• C. insulate basement floors
• D. add attic insulation

Answer: (D)

Adding attic insulation is typically the most cost-effective way to cut fuel costs because heat rises and the attic is a major route for heat loss. By boosting the insulation up there, you dramatically reduce the warm air that escapes into the attic and outside, which lowers the amount of fuel needed to keep the living spaces comfortable. Attic insulation generally offers a strong cost-to-savings ratio: materials and installation are affordable, and the payback period is usually short, especially if the attic is currently under-insulated. Other options are less cost-effective in typical scenarios. Installing baseboard heaters would raise heating costs rather than reduce them. Replacing windows can be expensive, and the savings depend on how leaky the existing windows are, often with a longer payback. Insulating basement floors helps somewhat, but the impact on overall heating costs is usually smaller than adding attic insulation, since most heat loss in winter is through the ceiling where warm air escapes upward.
