· Close your exterior doors and windows tightly when the AC is on. Save even more by turning off kitchen and bath exhaust fans.
· Change or clean your AC's air filters at least once a month to keep your system running at peak performance.
· Make saving automatic: Set your thermostat fan switch to "auto" to save energy. Leaving it in the "on" position keeps air running constantly.
· Block the sun from overheating your home! Inside, use shades, blinds and drapes. Outside, use awnings, trees and shrubs.
· Insulate your walls with injected foam insulation to help you save energy by keeping hot outside air from seeping through porous block walls – check with your local building supply company for details.
· Open interior doors so that cooled air flows freely throughout your home.
· Close unused air vents. If you have central AC you can close air vent in rooms you're not using so you're not paying to cool them.
· Use ceiling fans to cool off for less. Ceiling fans use no more electricity than a standard light bulb. However, be sure to turn fans off when you leave — they only cool people, not rooms.
· Install a programmable thermostat to adjust your temperature during the day.
· Replace halogen bulbs and CFLs with LEDs. Light Emitting Diode bulbs are more energy-efficient than halogen bulbs and compact fluorescent light bulbs while giving off the same amount of light.
· Use motion-detector lights for all your outdoor lighting – they’re convenient and efficient.
· Consider using timers to turn lights on in the morning and off during the day.
· Choose outdoor LEDs for outdoor lighting – they last up to 30 times longer than standard bulbs.
· Select light-colored or opaque lampshades. Place lamps in corners so they reflect light from two walls.
· Use microwaves and toaster ovens to cook or warm leftovers. You’ll use less energy than cooking with a conventional oven.
· Set your refrigerator temperature between 30 and 42°F. Use the power-save switch if you have one.
· Repair refrigerator door seals if you feel cold air around the closed door or if moisture is collecting.
· Keep your freezer full – it uses less energy than an empty one. For maximum savings, consider filling your freezer with gallon containers of water.
· Choose energy-efficient appliances. They don’t just save you money, but they’re good for the environment because they use less energy.
· Set your dishwashers on economy mode, to use less water and electricity.
· Turn off your dishwasher after the wash cycle — and let your dishes air-dry. You'll save energy and keep your dishwasher from heating up your kitchen.
· Use copper-bottomed pots and pans that use heat more efficiently when cooking on the stove.
· Keep stove reflector pans clean to reflect more heat upward while cooking.
· Turn off your oven or burners when food is almost ready and let existing heat finish the cooking for you.
· Use tight-fitting covers on pots and pans when cooking on the stove to shorten your cooking time and save energy.
· Match your pot size to the burner on your stove. Heat is lost when small pots are used on large burners.
· Turn off kitchen and bath fans immediately after use.
· Always wash with cold water, laundry detergent works just as well, and you’ll save 40 cents per load.
· Turn off your water heater until if you plan on leaving home for a few days. And you get back. Most models will reheat the water to the set temperature in about an hour.
· Stop that dripping hot water faucet. Leaky faucets not only increase water bills but also increase gas or electricity use for heating the wasted water.
· Install a timer for your water heater that will turn it off when you are not at home.
· Plug electronics into a power strip, then turn the strip off when not in use to save in energy costs.
· Consider a laptop next time you're looking to buy a computer – they use less energy than desktop computers.
· Set your computer to sleep or hibernate mode instead of using a screen saver so it uses less electricity during periods of inactivity.
· Unplug battery chargers when the batteries are fully charged or the chargers are not in use. Many chargers draw power continuously, even when the device is not plugged into the charger.
