Core Appliance Energy Fundamentals
1. Electrical Wattage vs Operating Hours
Wattage (W) indicates instantaneous electrical power draw. Operating hours define duration. Energy consumption (kWh) is the product of power and time divided by 1,000.
2. Understanding Duty Cycles
Refrigerators, air conditioners, and dehumidifiers cycle their cooling compressors on and off. The duty cycle percentage represents active compressor runtime relative to connected hours.
3. Nameplate Rating vs Real Draw
An appliance electrical nameplate states maximum peak electrical load for safety compliance. Average operational power draw is typically lower than maximum nameplate capacity.
4. State Averages vs Utility Tariffs
U.S. EIA state electricity averages represent total residential revenue divided by total kWh sales. Local utility bills may include tiered rate blocks, delivery fees, and fixed monthly meter charges.
