Install a programmable thermostat.
You could save as much as $180 a year by choosing a thermostat that has the ability to automatically adjust the temperature when you are not at home. Doing so could save about 15 percent on your heating bill annually. Some thermostats also have other energy-saving features, like filter-change reminders. Just make sure you choose a system that is easy to use.
Install ceiling fans.
Installation cost varies based on existing electrical work. A single fan on high speed generally uses about 50 to 100 watts of power, resulting in about 800 kilowatts per year for a home with four ceiling fans—far less than a central air conditioning system. While fans are not able to actually cool the air, they can relieve you of feeling hot, and using them in lieu of A/C will save you a large amount of energy. Just make sure to switch them off when you leave the room!
Seal any cracks around door and window frames with caulk.
This is a no-brainer. Eliminating cracks will take only a few hours and could pay you dividends. About 30 percent of a home’s energy loss happens at an entryway. If you’re looking to go green, this is an easy way to do so.
This tip is especially good for the environment. If you want to save on your energy costs, particularly in the summer, plant trees on the east, west, and northwest sides of your home. This will prevent the sun from coming through your windows and making your A/C work harder. Plant a tree to shade your central air unit, and you may save up to 35 percent on your home’s cooling costs.
Lower the temperature of your water heater to 120°F.
An average of 15 to 25 percent of a home’s annual heating costs are related to heating the home’s water. This adjustment will take little time, and you will hardly notice a difference—until you look at the heating bill! When implemented, you’ll save up to $400 a year.
Insulate your hot water heater with a blanket.
Especially if you have an older system, this small act could save up to 25 to 45 percent on your annual heating costs. Look for water heater blankets made specifically for your electric water heater.
