The average U.S. household has about 70 light bulbs. One LED (light-emitting diode) light bulb uses up to 850% less energy than old incandescent bulbs and and has the potential to last tens of thousands of hours, so you’ll be buying and changing bulbs less frequently.
The Lighting Facts label helps you buy the light bulbs that are right for you.
The brightness of the bulb is listed first on the label. While you may be used to thinking about brightness in terms of watts, it makes more sense to think in terms of lumens, or the amount of brightness a bulb provides—the higher the number, the brighter the bulb.
Then look at the light appearance or color of the bulb. The scale on the label will tell you whether the bulb is warm or cool.
The numbers shown are on a Kelvin (K) temperature scale.

During colder months:
Here are some other suggestions for saving energy this winter:
During the summer:
One of the quickest energy and money-saving tasks you can do is caulk, seal and weather-strip all seams, cracks, and openings to the outside. Up to 25% of air is lost through small cracks and holes! To identify air leaks, check around your walls, ceilings, windows, doors, lighting and plumbing fixtures, switches and electrical outlets. Look for gaps, improperly applied caulk and weather-stripping, and doors and windows that don’t close tightly.
After you identify all air leaks, do the following:
Run ceiling fans only when someone is occupying the room. Ceiling fans cool people not rooms. Using a ceiling fan allows you to turn up the thermostat about 4°F without any loss in comfort.
Check air filters at least once a month and change as needed.
We recommend using filters with MERV ratings of six to eight. Unless the system was designed for higher MERV ratings, it is recommended that an HVAC professional who is NATE-certified should be used to verify that the air flow does not restrict the performance of the system.
Heating and cooling professionals recommend turning your system off before changing the air filter. Make sure that the arrow on the filter - which indicates the direction of the airflow - is pointing toward the blower motor. Once you’ve made the change, turn your system back on.
Smart and Programmable Thermostats:
Being smart about how you control your temperature settings will help you save money and stay comfortable. Set your thermostat up or down a few degrees (suggested 68 degrees in the winter and 78 degrees in the summer) when you are away from home.
A programmable thermostat will automatically turn on the heating or air conditioning at times you schedule. Programmable thermostats can store multiple daily settings that you can manually override without affecting the rest of the daily or weekly program. Using a programmable thermostat allows flexibility and adds convenience, as temperatures will automatically return to normal before you wake or return home.
A smart thermostat is a Wi-Fi enabled device that automatically adjusts heating and cooling temperature settings for optimal performance. With a smart thermostat, it’s easy to schedule your HVAC to run less while you’re out for the day, so you’ll use less energy. Some common smart thermostat features:
To keep your electric meter from spinning, unplug devices that use power even when powered down such as CD or DVD players, cell phone chargers, camera and battery chargers, small appliances, video game consoles computers and TVs.
Consider plugging electronics into a smart strip so you can turn "unplug" many of them at the same time.
There are four primary ways to cut your water heating bills: use less hot water; turn down the thermostat on your water heater; insulate your water heater and pipes; or buy a new, more efficient model.
You can take steps to use less hot water and improve the efficiency of your existing water heating system.
Windows can be one of your home’s most attractive features. Windows provide views, daylight, ventilation and heat from the sun in the winter. Unfortunately, heat moving in and out of your home through windows can increase your heating and air conditioning bills. Energy-efficient windows and measures to reduce heat gain and loss can help save energy and reduce energy bills.
Look for the ENERGY STAR label when buying new windows. Also review ratings from the National Fenestration Rating Council (NFRC). NFRC ratings are included on all ENERGY STAR certified windows and provide a reliable way to determine a window’s energy properties and compare products.
