All of the following are potential benefits of using time-based electricity pricing programs offered by some utilities, except:
  1. Electric bill savings of over half of the regular kWh charge
  2. Hot water may run out if the metered water heater demand is too high during non-specified hours
  3. Less demand on the power grid at peak times
  4. Potentially cheaper water heater operating costs than with a traditional gas water heater
Explanation
Answer: B - The possibility of running out of hot water if using a utility-metered water heater is clearly a disadvantage rather than a benefit. With adjustments to the timing of hot water-using activities, this problem would be mitigated. In addition, many utilities that offer this type of program do not require the use of a metered water heater. The other three options are all benefits of signing up for a time-based electricity pricing program.
