How to Lower Your Electric Bill (13 Real Moves)

The electric bill is one of those quiet money leaks. You pay it, you grumble, and you move on. But most homes are throwing away real money every month on power they never actually needed. The good news is you do not have to sit in the dark or take cold showers to fix it. You just have to be a little smarter than your utility company. Here are thirteen real moves, roughly in order of biggest payoff, that add up to serious savings over a year.

Start With the Big Three: Heating, Cooling, and Water Heating

About half of a typical home's electric bill comes from heating and cooling the air and heating your water. That is where the money is, so start there.

• Move your thermostat 7 to 10 degrees for 8 hours a day. Do it while you sleep or while you are at work. The Department of Energy estimates this saves around 10 percent a year on heating and cooling. On a $180 monthly bill, that is close to $18 a month back in your pocket.
• Get a programmable or smart thermostat. A $30 to $130 unit does the setback for you so you never have to think about it. Most people earn that back in a season or two.
• Turn your water heater down to 120 degrees. Many are shipped set at 140. Every 10 degrees you drop saves a few percent on water heating, and 120 is still plenty hot for a shower.

None of this requires spending a dime up front except the thermostat, and even that pays you back fast.

Kill the Vampire Loads and Lighting Waste

"Vampire" or standby power is the electricity your gadgets sip while they are technically off. It is small per device but real across a whole house.

• Put your entertainment center and computer setup on a power strip and flip it off at night. The average home wastes roughly $100 to $165 a year on standby power, and this claws back a chunk of it.
• Switch your five most-used bulbs to LED. An LED uses about 75 to 80 percent less power than an old incandescent and lasts for years. Swapping a handful of high-use bulbs can save $50 or more a year.
• Use "smart" plugs on space heaters and window units so they cannot run all night by accident. A single space heater left running can add $30 or more to a month's bill.

Do Your Laundry and Dishes the Cheap Way

The machines themselves are not the villain. It is how and when you run them.

• Wash clothes in cold water. About 90 percent of a washer's energy goes to heating water. Cold-water detergent cleans everyday loads just fine, and this alone can save $40 to $60 a year.
• Clean your dryer lint trap every single load and let the dryer's moisture sensor do its job instead of running a fixed long cycle. A clogged trap makes the dryer work harder and longer.
• Skip the dishwasher's heated dry. Pop the door open and let dishes air dry. Same clean dishes, less power.
• Run full loads only, and if your utility charges more at peak hours, run them at night or early morning.

Seal, Shade, and Filter

Your heating and cooling system fights an uphill battle when the house leaks air. Help it out.

• Change your HVAC filter every 1 to 3 months. A dirty filter chokes airflow and makes the system run longer. A $10 filter can protect a $5,000 system and shave a few percent off cooling costs.
• Weatherstrip doors and caulk leaky windows. A $20 to $40 weekend project can cut heating and cooling waste noticeably. Hold a lit candle near a window edge on a windy day. If the flame dances, you found a leak.
• Close blinds on the sunny side in summer and open them in winter. Free heating and cooling from the sun, just by managing your shades.

Get the Utility to Help You Save

This is the move most people skip. Your utility often has programs that hand you money or lower rates.

Call the customer service line or check the website and ask three questions: "Do you offer a time-of-use rate that is cheaper if I run appliances off-peak?" "Do you have any rebates on LED bulbs, smart thermostats, or a home energy audit?" and "Do you offer a free or discounted energy audit?" Many utilities will do a home audit for free or close to it, and rebates on thermostats and bulbs are common. A single call can unlock $50 to $150 in rebates plus a cheaper rate structure.

Bottom line: You do not need one giant fix. You need a stack of small ones. Start with the thermostat setback, the water heater, cold-water laundry, and a call to your utility, and most households can trim 10 to 20 percent off the electric bill within a couple of billing cycles. On a $180 bill, that is $216 to $432 a year for a few hours of effort.
