How Power Consumption and Costs are Calculated
Appliance energy consumption measures the volume of work performed by electrical current over time, expressed in Kilowatt-Hours (kWh).
Once energy consumption is evaluated, operating cost and carbon releases are solved via:
Carbon Footprint = Energy (kWh) × 0.85 kg CO2
Where 0.85 represents the standard grid carbon emissions factor per electrical unit generated.
Energy Conservation FAQs
A Kilowatt-Hour (kWh) is the standard billing unit shown on electricity bills. It corresponds to consuming 1,000 Watts of electrical power continuously for exactly one hour. For example, a 100-watt TV running for 10 hours utilizes exactly 1 kWh of power.
Phantom load (or standby power draw) is the electrical current consumed by chargers, routers, TVs, and smart devices when they are plugged in but inactive. Standby power draw can account for up to 10% of standard domestic electrical usage.
Older electrical appliances (especially refrigerators and heat exchangers) degrade in mechanical efficiency. Worn seals, compressor leaks, and dust accumulation can cause older appliances to consume up to 40% more electricity than their rated label states.
