DescriptionTurn off the lights when you exit the house in the morning for the day. If no one is home to need the lights, energy is wasted and the life of the bulb is being consumed. Consider installing timers for lights to provide lighting and safety prior to your return in the evening.
- year round
Assumptions We MadeOnly one light left on usually. Turning off single light with 40 Watt bulb, out of house for 10 hours for a day. You would reap additional savings beyond our projection if a higher wattage bulb is in your fixture, if multiple fixtures are typically left on, and if you are out of the house longer hours.
Each time you carry out this action, the immediate impacts are:
- Saves 0.04 dollars
- Saves 0.40 kilowatt hours
- Saves 0.54 lbs of CO2
Some actions also have additional impact over time. For this action, these are:
Potential Annual ImpactWe assume that this action will be carried out daily (about 160 times a year). In this case, in a year you could save:
- 6.24 dollars
- 64.00 kilowatt hours
- 87.04 lbs of CO2
