DescriptionTurn off lights and take advantage of sunlight. During a sunny day, turn off lights and move your work to a window where sunlight is entering. Use the natural light rather than artificial light.
- year round
Assumptions We MadeSwitching from 60 W incandescent bulb (high wattage) not being used during half day (4 hour) period when sun is on that side of house. Conservatively speaking, you should be able to fulfill this action 100 days per year (average number of clear days for all of US). Some partially cloudy days would still allow for sunlight use.
Each time you carry out this action, the immediate impacts are:
- Saves 0.02 dollars
- Saves 0.24 kilowatt hours
- Saves 0.33 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:
- 3.84 dollars
- 38.40 kilowatt hours
- 52.16 lbs of CO2
