Which action directly reduces energy usage?

• A. Turn off lights where possible in areas not in use
• B. Check faucets and showers to ensure they are turned off
• C. Close doors behind you when spaces are not in use
• D. Report unusual outdoor water

Answer: (B)

The action that directly reduces energy use targets how energy is most often wasted: heating water. When faucets or showers are left on or not fully off, hot water is heated and used, and any waste means more energy is spent to heat that water. By checking that faucets and showers are turned off, you prevent unnecessary hot-water heating, cutting the energy draw right at its source.

Turning off lights or closing doors also saves energy, but those actions affect electricity and HVAC in a broader sense, whereas ensuring hot water isn’t being heated unnecessarily tackles a major energy contributor on a per-use basis. Reporting unusual outdoor water use doesn’t directly cut energy consumption.
