Calculating Electrical Energy and Cost: Calculating Electrical Energy And Cost Worksheet Answers
Electrical energy, measured in kilowatt-hours (kWh), is the amount of work done by electricity over time. It is calculated using the formula Energy = Power x Time, where power is measured in kilowatts (kW) and time in hours (h).
Common electrical devices and their typical energy consumption include:
- Refrigerator: 300-700 kWh per year
- Air conditioner: 1,000-2,000 kWh per year
- Electric oven: 1,500-2,500 kWh per year
- Electric water heater: 4,000-5,000 kWh per year
Understanding Electrical Cost
Electricity costs are determined by factors such as energy usage, demand charges, and time-of-use rates. Rate structures vary by utility company and may include:
- Flat rate: A fixed charge per kWh
- Tiered rate: Charges increase as usage increases
- Time-of-use rate: Charges vary depending on the time of day electricity is used
