Energy Saving Tips
Quick ways to save energy:
- Use ceiling fans to keep air moving, so you feel cooler without increasing
- Dry laundry loads right after each other so your dryer doesn't have
reheat for each load.
- Caulking around door frames and installing weather stripping
door openings are inexpensive and highly effective means of saving
- Deciduous trees with high, spreading leaves and branches can be planted
to the south of your home to provide maximum summertime roof shading.
Trees with foliage lower to the ground are more appropriate to the west,
where shade is needed from lower afternoon sun angles.
- Cutting a 15 minute shower in half can save substantially on yearly
hot water cost.
- In summer, use shades, blinds or curtains to keep sunlight out,
especially during the afternoon in rooms facing west.
- Don't block vents or ducts inside the house. Maintaining clear air
allows your cooling and heating system to work more efficiently.
Lighting Energy Saving Tips
Saving lighting costs goes way beyond turning off the light switch when
you leave the room,
although that's still a good idea. Here are a number of low-cost actions
you can take to
save energy and money:
- For each standard incandescent bulb you replace with a compact fluorescent
bulb, you can save from $10 or more on your electric costs over the life
the bulb (see table below). You get more hours of the illumination (compact
fluorescents have a life expectancy of 10,000 hours, compared to 750
to 900 hours for standard bulbs) and three to four times more lighting
efficiency. Start by replacing bulbs that are on for more than three
hours per day. Next,
replace bulbs that are in hard-to-reach places. You'll save time, effort
- When buying bulbs, look for the highest lumen-per-watts ratio. Lumens
measure the amount of light a bulb gives off, while watts measure how
energy a bulb uses. A typical lumens-per-watt ratio for an incandescent
is 15:1. This compares to 60:1 for a fluorescent bulb.
- Use brighter bulbs in areas where you do close-up work such as reading,
cooking and home projects. Use less bright bulbs in other areas.
- Keep light bulbs and fixtures clear of dust. Clean bulbs give off more
than dirty ones.
- Use natural light whenever possible. Make the most of natural light
by moving desk, reading chairs and workbenches closer to windows. Keep
in mind that lighter colors for walls, ceilings and floors reflect more
Incandescent Bulb and Compact Fluorescent Bulb Cost Comparison
