Req 8 — Reading Your Electric Bill

8.
Do the following:

This requirement takes you from wires inside the house to the cost of the power coming into it. You will read a meter or bill, figure out how much energy was used, understand why the total is more than just the energy charge, and think about ways your family can conserve power without making life miserable.

Requirement 8a

8a.
Read a meter associated with an electric bill. Determine the total power used since the bill, and the cost of that power.

Most home electric bills measure energy, not just instant power. The usual unit is the kilowatt-hour (kWh). One kilowatt-hour means using 1,000 watts for one hour.

If your family used 750 kWh during a billing cycle and the energy rate was 15 cents per kWh, the energy portion of the bill would be:

750 × $0.15 = $112.50

If you are reading a meter directly, you are usually comparing the current reading to the previous reading. The difference tells you how much energy was used during that period.

Helpful reminder

In everyday conversation, people often say “power bill,” but the bill mainly reflects energy consumption over the month.

Requirement 8b

8b.
Explain other charges on the bill that were taxes or fees.

The total on an electric bill is often larger than the energy-use line alone. Utilities may include:

These charges vary by state and utility, so your explanation should be based on the actual bill your family receives.

Mock electric bill with the usage line, energy charge, delivery charges, taxes, fees, and total due clearly highlighted

Requirement 8c

8c.
Discuss with your counselor five ways your family can conserve energy.

Energy conservation works best when it focuses on habits and high-impact devices. Good ideas usually save the most when they target things that run a lot, produce heat, or cool air.

Here are categories to think about with your family:

Five smart conservation strategies

Choose the ones that really fit your home
  • Lighting: switch to LEDs and turn off lights in unused rooms.
  • Heating and cooling: adjust the thermostat sensibly and keep filters clean.
  • Hot water: take shorter hot showers and lower water-heater waste.
  • Appliances: run dishwashers and laundry with full loads.
  • Standby power: unplug unused chargers or use advanced power strips for electronics.

The strongest counselor discussion usually includes both what your family could do and what tradeoffs matter. For example, lowering the thermostat saves money, but comfort matters too. The real skill is balancing convenience, cost, and energy use.
