On a February night, energy leaves a house by several energy leaks, including 1.50×103W by conduction through the ceiling, 450W by infiltration (airflow) around the windows, 140W by conduction through the basement wall above the foundation sill, and 40.0W by conduction through the plywood door to the attic. To produce the biggest saving in heating bills, which one of these energy transfers should be reduced first? Explain how you decide.
