SUMMARY
Lighting typically accounts for approximately 10-20% of a household's electricity consumption. To accurately estimate this, one must calculate the total kilowatt-hour (kWh) usage by assessing the number of lights, their wattage, and the average hours they are used per month. This consumption can then be compared to the total electricity bill to determine its significance relative to other appliances such as fridges, freezers, and washing machines.
