An internet search for ways to save energy at home usually results in good tips to save small amounts of energy, but they will likely not move the needle.
For example, washing clothes in cold water and turning off ceiling fans in rooms where you are not spending time frequently are great points of advice, but if you want home energy saving results, try these five easy projects you can easily do yourself.
1. Seal Recessed Light Fixtures
The first thing you can do to save energy at home and reduce drafts is seal up you recessed lights in ceilings that are below the attic. These common fixtures are secret gateways to the attic which means energy loss and comfort challenges. Most older recessed lights have ventilation holes so that heat from the bulb can escape. Energy customers with recessed lights typically have some of the biggest bills and comfort complaints.

2. Seal Attic Floor Cracks, Holes and Gaps
Similar to the recessed light problem, there are other holes and cracks in the attic floor that will lead to the communication of air between the inside of the home and the attic, or outside. Foam sealant can be purchased at the hardware store and it can be applied to the tops of walls, around light fixtures and to seal up holes drilled for electrical wires. All of these voids contribute to a high bill and uncomfortable living space.

3. Seal Accessible Leaky HVAC Ducts
Saving energy at home can be achieved when you put resources in the right place. According to the EPA and other studies, the HVAC ducts in your home can be leaky enough to account for up to as much as 30% of a household's total energy loss. Sealing ducts is not something that needs to be done by a contractor. This is a "weekend warrior" type of project that requires a little patience, a few materials and a little know how. Sealing ducts near the air handler will also help you the most and those are usually the places that are most accessible.

One way to fix leaky ducts is to use two-part spray foam.

4. Seal and Insulate the Attic Hatch
If you want to save energy at home and improve comfort, be sure to think about all of the places that you have access to an attic around your house. It is important to treat all of them. Typically, the attic access points around a house are made from 1/4" plywood or drywall. This is no way to separate the inside of your home from the attic (outside). A few pieces of insulation and a 10' piece of weatherstripping can go a long way!

5. Install a Chimney Balloon
If you have a fireplace, then you have another great way to save energy at home. Most people keep the damper closed when the fireplace is not in use, but usually it is made of metal. Chances are there is nothing stoping the flow of air through the chimney damper flap and out. Using a very simple blow up type device can really help to move the needle and decrease energy usage and improve comfort.
A great way to save energy at home and improve comfort is to seal the chimney with an attic balloon.
The attic ballon has a stem that can easily be accessed to blow up the device and create a nice seal in the chimney.
There certainly are ways to save energy at home without having to lift a finger, but if you really want to see a decrease in your energy bill and an increase in your comfort level than you will have to put a little thought and effort into getting a few things done.
