Look at these great tips from energy.gov!
Wash clothes in cold water to save $63 a year.
Use your window shades. Close blinds on the sunny side in summer to keep out the hot sun, and open them in winter to bring in warm rays.
Change to new and improved light bulbs. Reduce energy use from about a third to as much as 80% with today’s increasing number of energy-efficient halogen incandescents, CFLs and LEDs.
Lighting makes up about 10 percent of home energy costs. Save up to 75 percent of that energy by replacing incandescent bulbs with compact fluorescent bulbs (CFLs). They also last longer, saving money on replacements.
Placing lamps or TV sets near your room air-conditioning thermostat can cause the air conditioner to run longer than necessary because the thermostat senses heat from the appliances. Set them apart and save energy.
Look for the Energy Star label, the government’s symbol of energy efficiency, on a wide range of consumer products to save up to 30% on related electricity bills.
Use low-flow faucets and shower heads to save on water bills.
Clean or change filters regularly. A dirty furnace or A/C filter will slow down air flow and make the system work harder to keep you warm or cool.
Seal air leaks and properly insulate to save up to 20% on heating and cooling bills, while also increasing home comfort.
Running your air conditioning at 78°F instead of 72°F can save between 6 and 18 percent on your cooling bill. If you use air conditioning, a ceiling fan will allow you to raise the thermostat setting about 4°F with no reduction in comfort. Just make sure to turn it off when you leave the room (fans cool people, not rooms).
Well-planned landscaping isn’t just for aesthetics — properly placed trees around the house can save between $100 and $250 annually.
On average, households lose about 20 percent of their heated and cooled air through the duct system to the outside. To avoid wasting energy, have your ducts inspected to ensure they’re sealed properly and insulated if necessary.
Heating water can account for 14 to 25 percent of the energy consumed in your home. Turn down the temperature of your water heater to the warm setting (120°F); and wrap the water storage tank in a specially-designed “blanket” to retain the heat.
By using the microwave, toaster or a counter-top grill rather than an oven, you’ll use less energy and avoid excess heat that increases room temperature.
Leaving a computer on all day can cost about 21 cents per day, or about $75 per year. Unplug electronics and appliances when not in use – a task made easier by using multiple-outlet strips, which can turn everything off with the flip of a switch.
Install a programmable thermostat to save up to 10% on cooling and heating costs. You can save up to $150 a year. Use one that can automatically turn off your cooling system when you are not home, and turn your system on in time for you to arrive home to a cooled house.
