SUN IN
SAVE $90
If you have ample daylight coming in through the windows, open the drapes, turn off the inside lights, and let the sun illuminate your home. You could save up to $90 or more per year on your energy bill by turning off just five 60-watt bulbs for eight hours each day.
Studies have shown that working in natural light improves comfort level and mood, making people more productive. Substantial research has also found a relation between artificial lighting—or lack of natural light—and a range of problems including depression, increased stress, headaches, afternoon tiredness, sleep disturbances, and concentration and learning difficulties.
