Tame The Energy Hogs

Give Your Home an Energy Tune‑Up

There are many free and low-cost ways to save energy and lower your electric bill, while increasing home comfort and helping to slow global warming. Tackle the top power hogs first for maximum results. In Florida homes, air conditioners gobble the most power—about 40-50% of energy use in most homes. Always-on electronic devices, hot water heaters, and pool pumps each use about 12-15% of the total.

Get Started

We’ve sifted through all sorts of energy saving tips to find the ones that are easiest and most effective.  In many cases, the solutions are free—you just make a small tweak to the way you do things. There are also many low-cost solutions that only require a quick trip to the home improvement store.

Cooling and Heating

Step 1

Take charge of your thermostat

Cost: $0-250

smart thermostats conserve energy
  • Summer – Set your thermostat to 78 Fahrenheit and turn up to 82 F when away for more than 4 hours. Winter – Set your thermostat to 68 deg and turn down to 65 deg when you are away. Keep the fan on auto to reduce runtime and control humidity. You can save 5% on heating and cooling costs for every degree change. Free
  • Install a programmable thermostat to automatically set the temperature to your daily schedule. DIY $20–$50
  • Even better, install a smart thermostat for an additional 10-15% in efficiency and savings. A smart thermostat lets you use your smartphone or smart home hub to control temperature settings both at home and away. They even learn your schedule and adjust temperatures accordingly. DIY $100–$250

Step 2

Use ceiling fans

Cost: Free

Using fan can conserver energy

Using a ceiling fan can help save energy, but only if you also raise the thermostat by at least 2 degrees (or at least avoid turning it down).

  • Turn ceiling fans off when you leave the room. Fans circulate air to make you feel cooler, but don’t actually cool the air. A single fan running all day can add $6 to your monthly energy bill.
  • Set the ceiling fan direction in summer to counterclockwise to help create a downdraft, which creates a direct, cooling breeze. Change your fan direction in winter to clockwise to create an updraft and circulate warm air around the room.

Step 3

Maintain your system

Cost: $0-150

energy efficient air conditioners can lower utility bills
  • Keep interior doors open and vents open and unobstructed by furniture to help your A/C circulate air and increase efficiency by up to 40%. FREE
  • Keep leaves, shrubbery, and debris at least 18 inches away from your outdoor A/C condenser unit to avoid blocking airflow. FREE
  • Change or clean the filter at a minimum every 3 months (check it monthly) using the proper size. Write the installation date on filters with a felt-tip marker for an at-a-glance reminder. DIY $5–10
  • Get an annual maintenance check-up. A professional HVAC contractor can inspect and clean your system to ensure it operates efficiently and prevents costly breakdowns. A/C maintenance checklist. Professional Service $100–150

Step 4

Seal and insulate your home against air leaks

Cost: $0-1,000+

Sealing and insulating your home is one of the most cost-effective ways to make your home more comfortable and energy efficient, with savings of 20% or more on heating and cooling costs. Bonus  benefits include reduced outside noise, pollen, dust, and insects entering your home, and better humidity control. Warm and cool air can escape through leaks in outer walls, floors, ceilings, doors, and windows. Energy losses from all the leaks, holes, and gaps are like having a window open every day of the year!

  • Wipe away dirt and grime from the tracks of your sliding glass door. A dirty track can ruin the seal, creating gaps for air infiltration. FREE
  • Seal doors and windows with weatherstripping, like door sweeps, spring metal strips, v-shaped vinyl, or adhesive-backed foam. DIY $5–10 each
  • Seal leaky air conditioning ducts to prevent cool air from escaping into the attic. If the ceiling is dirty around your air conditioning vents or there are “attic smells” in the house, this could be a sign of duct leaks. While the sealing materials are relatively inexpensive for DIYers, having an A/C professional inspect and seal your air ducts will save you time and frustration and yield better results. Duct Sealing Fact Sheet Professional Service $1000+
  • Seal your attic and add insulation. Hidden holes into your attic around recessed lights, air duct vents, stove and dryer vents, and behind electrical outlets can allow cool air to escape. If your home was constructed before 1982, you may not have the recommended 10-14 inches of insulation in your attic.

Step 5

Make Shade

energy efficient outdoor space
  • Keep sunlight out of your home during summer months with window shades or window film.
  • Plant shade trees on the east and west sides of the house. A well-located mature shade tree can save up to 20% on household cooling costs. Use the Arbor Day Foundation’s Tool to find a tree give-away program in your area, choose a tree, and find the best location in your yard for the most savings.

Always On Electronics

Step 1

Power Off

Cost: $5-25

unplugging electronics when not in use can reduce your electric bill
unplug to conserve energy

The devices and gadgets of modern life waste huge amounts of energy when idle—an estimated 50 power plants worth of energy nationally every year! Electronic devices such as computers, televisions, and stereos and gaming systems consume electricity even when they are turned off, sucking up and wasting 12 percent of a home’s annual electricity use. That’s why adapters plugged into the wall feel slightly warm even when not in use.

  • Unplug electronics and appliances (such as coffee makers) when not in use. For hard-to-reach devices, plug them into a power strip then click off the power strip. DIY $5
  • Even better, use smart power strips and plugs to power off devices automatically when not in use. Smart power strips can detect if the master device is in sleep mode or has been turned off then turn off all other attached devices at the same time. For example, you can plug electronics such as your home entertainment system into a smart power strip to automatically cut power to cable boxes, speakers, and game consoles when the TV is turned off.

Water Heater

Step 1

Heat Efficiently

Cost: $0-1,500+

insulate your water heater to conserve energy
save energy with a water heater timer

Water heaters are typically among the top three energy hogs in the home. The average family spends about $15–20 per month to heat water. To trim those costs, heat more efficiently and use less hot water.

  • The default setting of most water heaters is a scalding hot 140 Lower the temperature by just 10° F to save 3–5% off your energy costs. FREE Step-by-Step DIY Project 
  • If your water heater tank feels warm on the outside, insulate the tank with a wrap. DIY $40
  • Drain about a quart of water from the water tank every 3–6 months to remove sediment that lowers the efficiency of your water heater.
  • Install a timer to turn off your heater at night and when on vacation. Even better, install a smart water heater to optimize water heating with your usage patterns. DIY $50–150
  • If your water heater is more than 10 years old, consider replacing it with an ENERGY STAR high-efficiency heat pump water heater. This technology moves heat from the air into the water, releasing cool dry air (like a refrigerator in reverse). Perfect if your water heater lives in your hot Florida garage! These water heaters are pricier than conventional electric models, but their improved efficiency will lower water heating costs by 50%, plus you may receive a $300 Federal tax credit. Professional Installation $1500+

Wondering if you should consider a solar water heater?

Step 2

Use Less Hot Water

Cost: $0-20

improve energy efficiency by washing laundry in cold water
  • Wash and rinse your clothes in cold water to reduce energy use by as much as 90% and save $0.50 per load. Unless your clothes are heavily soiled, cold water is better for your clothes anyway. FREE
  • Run your dishwasher instead of hand washing dishes; it uses one-third less water when running full loads. FREE
  • Install water-conserving showerheads and faucet aerators. You can save 25–60% more water per showerhead, using less hot water. DIY $20


Pool and Spa Equipment

Step 1

Optimize Your Pump

Cost: Free

energy efficient pool and spa pumps reduce electricity usage

We Floridians love our swimming pools. But running a pool pump 8 hours a day can add $40–60 per month to your electric bill. Careful maintenance of your pool’s water clarity and chemical level can reduce the amount of time the pump needs to run and save $4–5 per month for every hour you cut back.

  • Limit run time to six hours per day in the summer and four hours per day in the winter. FREE
  • Set your spa heater to less than 104○ Fahrenheit, heat only when you plan to use it, and keep it covered. FREE
  • When upgrading, be sure to look for ENERGY STAR variable speed pumps to ensure efficiency.

Step 1

Switch to LED

Cost: $1.50-30

Lighting isn’t typically a big energy waster in most homes, but light-emitting diode (LED) bulbs are a smart choice for lights you use several hours a day. LED bulbs last 10 times longer than traditional incandescent bulbs, so they’ll rarely need replacement, and they are 75% more energy-efficient too. DIY $1.50

Shopping for new LED bulbs presents an overwhelming number of choices. Let’s break it down:

  • Step 1 – Look for the ENERGY STAR Label
  • Step 2 – Decide how much light you need – remember that brightness is measured in Lumens, not Watts. LED bulbs use far fewer Watts for the same brightness.
  • Step 3 – Check the package to make sure the bulb type is matched to your use (i.e., dimmable, enclosed space, outdoor, etc.)
  • Step 4 – Choose a light color from warm to cool.

Watch: How To Choose Lightbulbs

Automatic switches can enhance lighting efficiency and safety:

  • Install a dimmer switch to adjust the light level, save energy, and extend the life of light bulbs. (First make sure your LED light bulbs are compatible with dimmer switches.) DIY $15
  • Install a smart switch to automatically turn on the lights you use most when you get home and off when you leave. DIY $20
  • Use timer plugs, light-sensitive photocells or motion detectors to automatically turn your lights on and off indoors and outdoors. DIY $5-30

What’s the difference between ENERGY STAR and Energy Guide

Both the ENERGY STAR and the EnergyGuide labels are intended to help you make smart energy choices when shopping for new appliances and electronics. The blue ENERGY STAR label will help you easily identify which products meet strict guidelines for saving energy set by the EPA. The yellow and black EnergyGuide can be used to directly compare your top choices and give you an estimate of the energy use and operating cost.

Calculate What You Would Save by Going Green

If I turn off my water heater to save energy, won’t I end up using more energy to reheat the water?

Although you will use some energy to reheat water after your heater has been turned off, it will still be less energy overall compared to having your heater on all hours of everyday. Modern water heater tanks are insulated, so all you really need is to turn it on an hour or two before you plan to use the shower. Dishwashers don’t rely on hot water from your tank, they heat the water themselves.

Calculate Your Energy Savings

What can I do to avoid wasting energy when I’m on vacation or when I close up the house for the season?

There are several ways to save energy while you’re away:

  • If you are not going to be home for a while, turn your AC up to 82 degrees or higher in the summer and 65 degrees or lower in the winter. If you can program your thermostat, set it to 72 degrees for two hours every morning before the sun’s up and at 88 degrees the rest of the day to prevent mold.
  • For even more savings, use portable dehumidifiers (1 for every 1000 sq. ft.) instead of the AC. You can set them at 58% by sinks and showers, but make sure to have them in a place where the water can drain.
  • Turn off and/or unplug all of the systems and electronics you will not need like your water heater, TV, internet, toaster, microwave, etc.
  • Set your pool pump to run no more than six hours a day.
  • If your fridge/freezer is empty, turn it off (including the ice maker), clean it, and prop the doors open. If you want to leave it on, turn it to the warmest setting.

Calculate Your Energy Savings

Will LED lights save more money than just turning lights on and off when needed

LED bulbs are 75 – 80% more efficient than incandescent bulbs, which means in order to save the same amount of money by turning off incandescent bulbs, you would need to have your lights off 75 – 80% longer than you would if you had LEDs. For example, having an LED light bulb on for 4 hours uses the same amount of energy as a traditional incandescent bulb does in just 1 hour.
