There are many options to choose from when it comes to appliance use and upgrading. Here are some to consider:
Get the right size. Just as you should get the right air conditioner for the size of your room, don't purchase more refrigerator space than you need (and remember that top-freezers are the most efficient configuration).
Hand-washing dishes can be efficient if done with two wash basins, one with soapy water and one to rinse, rather than using a flowing tap and an open drain.
Conserve hot water by reducing shower times, installing aerators on taps and 1 gallon-per-minute or less low-flow showerheads and avoiding baths.
Consider a solar water heater to cut your water bills. They are often used with an electric or gas backup. The Energy Star site states that they cut your heating bills in half.
Savings
Upgrading from a 10-year-old 19 cubic-foot side-by-side refrigerator to an Energy Star model would save you 615 pounds of heat-trapping pollutants and $54.67 every year. Operating it efficiently would save 180 pounds and $16 annually. Recycling your old second fridge could trim two-thirds of a ton of heat-trapping pollutants at a savings of $1,192 on your energy bill every year.
Washing half your loads in cold water could save 97 pounds of heat-trapping pollutants and $10.40 from your energy bill annually.
Line-drying half your loads could save you 362 pounds of heat-trapping pollutants and $32.13 annually.
Running your dishwasher more efficiently could save you 243 pounds of heat-trapping pollutants and $47.04 annually.
Lowering your water heater temperature by 20 degrees from 140 degrees to 120 degrees could save you 274 pounds of heat-trapping pollutants and $24.32 annually.
Switching to a new Energy Star-rated air conditioner could save you 127 pounds of heat-trapping pollutants and $11.31 annually.
