Energy Star label indicates energy/water needed for operation is 10-50% lower than a non Energy Star appliance.

• A. 5-15%
• B. 0-5%
• C. 20-60%
• D. 10-50%

Answer: (D)

Energy Star labels signal that the appliance uses less energy (and often less water) than a standard model. The typical efficiency improvement is about 10% to 50% lower energy use, depending on the product category. This range best fits the actual standards, reflecting the general savings Energy Star aims to deliver. Gains as small as 0–5% or 5–15% would understate what Energy Star criteria usually require, while 20–60% overshoots the common upper bound for most products.
