You can save money on energy with these five green upgrades for your home. The upgrades increase the value of your home and make it more marketable when you are ready to sell it.

Start by taking an inventory of your home to see how and where you can save energy. Evaluate the cost of new appliances, repairs and replacements that may be necessary. You may be able to make minor seasonal repairs yourself.

1. Doors and windows

Replace old doors and windows that allow air to leak in or out of your home. Wood window frames are now considered better than aluminum frames. Windows should fit tight with a good seal.

Windows can be opened in nice weather to allow air to circulate but you do not want cold air in the house when you are trying to heat it. Storm windows may be necessary on the side of your house that gets strong wind gusts, rain and snow.

Doors that are old and do not hang properly can allow cold air, rain and dirt to seep into the house. This makes your heating and air circulation system work harder. Doors need to be replaced and/or sealed with weather stripping if you live in an area that gets rain, wind and snow.

2. Seal cracks and leaks

Use caulk to seal all cracks in the base of your house where it meets the ground. This happens occasionally. Seal cracks in basements or garages. You may find cracks around doors and windows that can be easily sealed with commercial sealant found at home improvement stores.

Check your cooling and heating system ducts. Tape any leaks or replace the ductwork if necessary. You can be loosing hot or cooled air through leaking ducts. Consider replacing your HVAC system if it is old and not working well.

Do not seal off vents to rooms you don't want to heat or cool. That only makes the HVAC system work harder. A ceiling fan may circulate warm or cool air at a lower cost than your HVAC blower.

Install a programmable thermostat to control temperature in your home 24/7.

3. Update appliances

Energy Star appliances are the most efficient in saving energy and utility costs. This government program rates water heaters, dishwashers, washing machines, dryers and lighting fixtures based on their cost per electrical unit.

Modern on-demand electric hot water heaters may cost more but they on do not have a tank that must be kept at a constant temperature to supply hot water. New conventional gas and electric hot water heaters are now more energy-efficient.

4. Update lighting

LED (light emitting diode) lighting saves energy. LED fixtures can save up to 85 percent on lighting cost. LEDs can be used indoors and out. Change to LED lighting and energy-saving spiral bulbs gradually as you replace bulbs and fixtures. A 5-watt LED light can replace a 40-watt bulb. LEDs lights can last up to 25,000 hours in contrast to the average incandescent bulb with a 1,200-hour lifespan.

Pendant lights, task and area lighting are more economical than overhead lights in the average room. The light is focused where it's needed.

5. Insulate

Attic areas under roofs can be insulated with the material that holds in warmed or cooled air. This keeps air from leaking out through the roof. Insulating material can also be used in walls and basements.

Other energy-saving upgrades can include solar panels, energy recovery ventilator and geothermal systems where they are available. These upgrades are more costly but they save money over time and increase the value of any home.
