In the average home, more than half of the energy used is for heating and cooling. A few simple steps can make your home more efficient in this area.

It is important to make sure heating and cooling systems are properly maintained and insulated.

Choose a programmable thermostat if possible so that the temperature can be set according to your schedule. Keep it set at a reasonable temperature, as close as possible to the outdoor temperature without being uncomfortable.

Never place a lamp or television near the thermostat. It will sense the heat given off by these items and not run efficiently.

If you don't have ceiling fans, consider installing them. They keep the air circulating and allow the air conditioner to work more efficiently. When ceiling fans are operating, you should be able to raise the thermostat 4 degrees with no discomfort.

Last, get a home energy audit. Most energy companies offer them and you will be made aware of any leaks, bad insulation, and appliances that may need to be replaced.

Appliances and home electronics account for about 20% of the average household energy bill. Cutting energy in this area requires just a few changes in habits.

Some appliances such as televisions, computers, etc. continue to draw electricity even when they turned off. Plug your electronics into a power strip and just turn off the power strip when the items are not in use.

Laptops use less electricity than desktops. Screen savers don't save energy. Choose sleep mode instead, or better yet, turn your computer off when it's not in use.

Always wash and dry full loads of laundry. Keep towels and heavier items in separate loads from light weight items. Clean the lint filter on your dryer after every load and don't run the dryer longer than necessary. Or, if you're willing to go the extra mile, line dry your clothes.

Run your dishwasher only for the wash cycle. Then, open the door and let your dishes air dry.

Replace traditional light bulbs with compact florescent bulbs. They use a quarter of the energy and last ten times longer.

Take advantage of daylight. Let in the sunshine instead of turning on the lights.

Dimmers, timers, and motion or occupancy sensors can also help cut lighting costs.

When replacing old out of date appliances, look for those that have earned an Energy Star rating. This means they have met strict energy efficiency guidelines set by the US Department of Energy and the EPA. The Energy Star rating is not just for appliances. Heating and cooling systems, windows, even entire homes can be Energy Star rated if they meet the requirements.
