 Energy Saving Tip for Heater and Air-Conditioner 

1. If your home has a central heating and cooling system, then periodically check all of the vents (especially floor vents) for possible obstructions such as furniture or rugs.

2. If your home doesn't have central heating, then make a habit of letting out or bleeding any possible air pockets from all of your hot water radiators. The U.S Department of Energy recommends doing this at least once every heating season.

3. Also all hot water radiators, baseboard heaters as well as floor and ceiling vents should be cleaned on a seasonal basis. In homes with central HVAC systems, cleaning of floor and ceiling vents should also be preformed every season.

4. In homes with central HVAC systems, it's incredibly important to change the air filter every 4 to 6 weeks, not months. Many homeowners often overlook this simple and inexpensive maintenance procedure. In the summer a dirty filter will force your AC unit to work harder to push cool air through your ducts and likewise during the winter months. Many homeownersoverlook their a/c and furnace filter simply because they (like me) are prone to forgetting. There are several great websites that offer automatic email reminders.

5. Consider purchasing a ventilated outdoor cover for your a/c unit. These covers are inexpensive and will provide your unit some much needed shade during the summer months. An a/c unit operating in the shade consumes 10% to 15% less electricity than a unit that's exposed to the scorching sun.

6. Within your comfort level, manually turn down or setback your thermostat during the winter and manually and turn up or set up during the cooling season. Every degree that a thermostat is set back or up translates into energy savings. However keep your families comfort well in mind.

7. Consider purchasing a programmable thermostat. There relatively inexpensive, easy to install and more importantly allow for automatic scheduled temperature set backs and set ups. This allows homeowners to effortlessly take advantage of the scheduled or habitual time periods that there often not home.

 Energy Saving Tip for Home Lighting

1. First and foremost, keep your windows as clean and clear as possible. Just cleaning your windows can improve transparency by as much as 20%.

2. When decorating a room, take into consideration the direction of the room. South and west facing rooms receive plenty of natural light. So if you're decorative taste calls for darker colored window treatments, paints and furnishings, consider these rooms first. Use lighter and more transparent colors in east and north facing rooms to further maximize on the limited amount of natural light these rooms receive.

3. In general avoid using dark and heavy curtains and drapes. Instead consider energy saving window treatments such as cellular or honeycomb shades. These treatments actually reduce costly heat loss and heat gain better and there considerably more transparent than dark curtains and drapes.

4. Switch to energy star certified CFL light bulbs. Start with the most used light fixtures through out the house. Bedroom lamps and living room lamps generally make good choices.

5. CFLs are not all the same. They come in different shapes and sizes, some types are designed for certain type of light fixtures. Knowing these differences will maximize the energy efficiency of your home lighting.

6. CFL light bulbs are efficient because there designed to use considerably less electricity (measured in watts) to produce the same amount of light (measured in lumens). When making the switch this must be considered. In short replace a 60 watt traditional bulb with about a 13 watt CFL bulb.

    Someone that know many Energy Saving tips and do it already, but they can't achieve their target to save energy cost for their home, why? i think.

    Have you ever heard "If you can't measure you can't control" it's true in Energy Saving too, if you measure how and how many you use energy you can control it and saving in easier way.
