Understanding Your Lighting Energy Costs
How to Calculate Lighting Costs
The total cost of lighting depends on three main factors: wattage, usage time, and electricity rates. To calculate your lighting costs, multiply the total wattage by the hours used, then convert to kilowatt-hours (kWh) by dividing by 1000. Finally, multiply by your electricity rate.
Energy-Saving Tips
Consider upgrading to LED bulbs, which use up to 75% less energy than traditional incandescent bulbs. Installing motion sensors or timers can also help reduce unnecessary usage. Regular cleaning of bulbs and fixtures can improve efficiency.
