Differentiate net energy savings from operating cost savings.

• A. Net energy savings are monetary; operating cost savings are energy units
• B. Net energy savings and operating cost savings are identical
• C. Net energy savings measure savings in energy units; operating cost savings are monetary savings influenced by prices and tariffs
• D. Net energy savings ignore price factors

Answer: (C)

The main distinction is that net energy savings quantify the reduction in energy use, expressed as energy units (like kWh or therms), while operating cost savings quantify the money saved on energy bills, which depends on energy prices and tariffs. Net energy savings reflect a physical reduction in consumption, independent of price signals. Operating cost savings translate that energy reduction into dollars by applying the price per unit, and thus are influenced by rates, charges, and tariffs. Because of this difference in what they measure and how they’re valued, describing net energy savings as energy units and operating cost savings as monetary savings affected by prices and tariffs is the most accurate. The other options mix up units or claim they’re identical, which doesn’t align with how these measures are defined.
