Question

residential water heaters use about 17% of all the electricity produced in the united states. they consume more energy than all other household appliances combined. which of the following activities can help reduce residential electricity consumption due to water heaters? choose 1 answer: a taking hot baths instead of brief hot showers to reduce the amount of hot water used b turning up water heater thermostats to reduce the electrical load c adding insulation to tank water heaters to reduce the electrical load d using tank water heaters instead of tankless water heaters

Explanation:

Taking hot baths uses more hot - water than brief hot showers, increasing electricity use for heating water. Turning up water - heater thermostats increases the electrical load as more energy is needed to heat water to a higher temperature. Tankless water heaters are more energy - efficient than tank water heaters. Adding insulation to tank water heaters reduces heat loss, so the water heater doesn't have to work as hard (less electrical load) to maintain water temperature.

Answer:

C. adding insulation to tank water heaters to reduce the electrical load
