Energy Wasters in Your Home (and office)

Your Energy Bill Breakdown
Energy doesn’t come cheap.
According to Maria Vargas, spokesperson for EnergyStar, a division of the Environmental Protection Agency (EPA), energy bills can differ
depending on the size and location on your home. However, the average household spends about $2,200 a year. The good news is these costs can be
Energy Star, a program started in 1992 to help reduce greenhouse gas emissions and lower energy costs for consumers, offers
suggestions for how to reduce your annual electric costs by a third. In other words, you can save about $700 a year on electricity. Last year,
Vargas points out, “Americans saved about $17 billion on energy bills and reduced greenhouse gas emissions by nearly the equivalent of 30
Using data compiled by EnergyStar, MainStreet breaks down your energy bill and identifies the biggest wasters to help you save money
(and reduce greenhouse gas emissions!) this winter.
“If you really want to cut back on your energy use, you need to focus on heating and cooling your home,”
Vargas says. That’s because these two categories combined, account for 46% of your overall electric bill.
While most homeowners can’t afford a complete overhaul of their homes’ heating, ventilating and air-
conditioning (HVAC) systems, some changes can increase energy efficiency and include:
• Installing a programmable thermostat, this allows you to set temperatures for specific times of the day. These
devices can save about $180 each year on energy costs.
• Change air filters regularly. The harder your HVAC unit has to work, the more it eats away at your energy. Filters
should really be changed out monthly, especially during the summer and winter months when the HVAC unit
has a heavy workload. If you find this tedious, EnergyStar suggests changing filters a minimum of every three
• Seal your heating and cooling ducts, especially those running through the attic, crawlspace, unheated
basement or garage. This will improve the efficiency of your HVAC unit by as much as 20%.
According to EnergyStar, your water heating system accounts for 14% of your energy bill. Monetarily
speaking, the average household spends $400-$600 per year on water heating. To reduce this expense,
lower standby losses, such as heat that escapes the water heater and seeps into the surrounding basement
area, as well as the amount of hot water you use in your home.
When set too high, or at 140 degrees Fahrenheit, your water heater can waste anywhere from $36 to $61
annually in standby heat losses, and over $400 thanks to overall consumption. Lower that expense by
bringing the heater’s thermostat to 120 degrees Fahrenheit or below.
In EnergyStar’s breakdown, lighting accounts for 12% of bill, but it also represents one of the easiest fixes. In
fact, by simply replacing five of your standard incandescent light bulbs with compact fluorescent light bulbs,
you can save $70 a year.
Appliances only account for 13% of electric bills, so naturally, most people don’t upgrade to an energy
efficient toaster. Still, if you are committed to reducing the amount of energy you use, you need to focus on
larger appliances that use a heat coil, such as a refrigerator or washer and dryer. To do that, make sure that
your fridge’s filters are cleaned regularly, and consider using only cold water to wash laundry loads. That can
save $30 to $40 each year.
But don’t be too stingy, Vargas says. Consider replacing a major appliance, like a refrigerator that is 10 to 15 years
old. This may help you save in the long term as new technology is constantly subject to federal standards that
adjust every year.
An appliance or device that is plugged in, sucks up energy. Despite being turned off, it is one of those money-draining culprits. According to EnergyStar, this includes most electronic devices, especially those that use some sort of display, like a television, laptop or DVD player.
Slaying energy vampires won’t lower your energy bill significantly — electronics only account for about 4% of
the total cost — but it’s important to keep them in mind, as they consume 75% of the electricity used to power
home electronics and appliances.
The best way to eliminate this phantom menace is not only to turn energy vampires off, but unplug them. This may be easier said than done, but unplugging a laptop in between uses isn’t particularly problematic.
However, doing so with your television would require you to wait for the cable to reboot every time you wanted to watch a program.
As an alternative, EnergyStar suggests plugging your television and/or DVD player into a power strip and then turning that off when your television is in stand-by mode. Put your computers on sleep mode, or manually
turn off the monitor in between visits, as opposed to utilizing a screen saver, which, contrary to popular belief,
does not reduce energy output.
Also, make sure you unplug a battery charger or adapter as it continues to draw energy even when the product no longer needs it.
Put Stand By on Stand by
The final 11% of your electric bill comprises devices that don’t exactly fit into any particular category. This
includes dehumidifiers, external power adapters and video game consoles, which are all considered energy
An Xbox 360, for example, if left on the draws approximately 1,000 kWh/yr. The PS3 draws 1,300 kWh/yr.
According to EnergyStar, these values drop dramatically when users routinely turn the device off after use –
lowering annual energy levels down to 110 and 120 kWh/yr – respectively. Since it costs about 12 cents per
kWh/yr in the average residential home in the U.S., it costs $120 if to leave your Xbox plugged in for the entire
To lower these costs, unplug the devices when you are not playing and only resort to stand-by mode as, well,
a stand-by. Energy Star estimates that stand-by power accounts for more than 100 billion kilowatt hours
(kWh) of annual U.S. electricity consumption, and $11 billion in annual energy costs.
