1. Identify the wattage of the LED bulb and the equivalent wattage of the incandescent bulb.
2. Determine the usage hours per day for the bulb.
3. Calculate the daily energy consumption for both the LED and incandescent bulbs by multiplying the wattage by the usage hours.
4. Multiply the daily energy consumption by the number of days in a year to determine the annual energy consumption for each bulb.
5. Calculate the energy savings by subtracting the annual energy consumption of the LED bulb from the incandescent bulb.

For example, let’s say you have a 60-watt incandescent bulb and a 10-watt LED bulb, both used for an average of 4 hours per day:

Incandescent bulb:

Daily energy consumption = 60 watts * 4 hours = 240 watt-hours

Annual energy consumption = 240 watt-hours * 365 days = 87,600 watt-hours or 87.6 kilowatt-hours

LED bulb:

Daily energy consumption = 10 watts * 4 hours = 40 watt-hours

Annual energy consumption = 40 watt-hours * 365 days = 14,600 watt-hours or 14.6 kilowatt-hours

Energy savings = Incandescent bulb annual energy consumption – LED bulb annual energy consumption

= 87.6 kilowatt-hours – 14.6 kilowatt-hours = 73 kilowatt-hours

In this example, switching from a 60-watt incandescent bulb to a 10-watt LED bulb would save 73 kilowatt-hours of energy per year.
