Which action would not align with energy-conservation practices?

• A. Leaving lights on when not in use.
• B. Turning off unused lights.
• C. Fixing drafts around windows.
• D. Opening windows for cooling.

Answer: (A)

Energy conservation in buildings means using only the energy you need and minimizing losses. Leaving lights on when they’re not needed is wasteful because lighting consumes electricity even when no one is present, raising overall energy use and costs. Turning off unused lights directly reduces demand. Fixing drafts around windows lowers heat transfer, so less heating in winter and less cooling in summer, which cuts energy use. Opening windows for cooling can be a useful natural-ventilation strategy when weather and indoor conditions permit, though it can undermine efficiency if heating or cooling is running and conditioned air escapes. The action that would not align with energy-conservation practices is leaving lights on when not in use.
