An absolute must with a million and a half uses. But do not buy just any plastic wrap. Go to a restaurant supply store and buy a large roll of restaurant plastic wrap. It sticks much better than the common grocery store plastic wrap and is much cheaper per foot.

If you enjoy eastern cuisine, you can buy a speciality hob with a wok burner. Similarly if you are a BBQ fan, choose a BBQ grill. If you are left handed, go for front rather than right hand side controls as this eliminates the risk of reaching across the heat. If you cook for a large family, more than four rings may be useful, and if you have young children it may be worth considering paying a little extra for a hob guard or in the case of gas, choosing an automatic re-ignition or cut off device should the flame blow out.

You can also maximize the efficiency of appliances you already own through regular maintenance and tune-ups and system upgrades. Examples of some things that you can do are:

• Check air filters in heating and cooling systems monthly during the seasons they are in use and clean and replace them as necessary.
• Clean air vents, baseboards, and radiators regularly and keep them unrestricted by furniture, carpets, or drapes.
• Release trapped air from hot water radiators once or twice a season by opening the valve until nothing but water comes out.
• Follow prescribed maintenance (e.g., maintaining certain water levels in steam heat systems).
• Install an insulating jacket on your hot water heater, insulate hot water pipes, and lower the water heater temperature.
• Clean refrigerator coils yearly and maintain internal temperatures between 36 degrees F (2.2 degrees C) and 38 degrees F (33 degrees C) for the refrigerator compartment and between 0 degrees F (17.8 degrees C) and 5 degrees F (15.0 degrees C) for the freezer compartment.
• Move the refrigerator if it is currently located near the stove or dishwasher.
• Regularly defrost refrigerators that do not have a completely automatic defrost capability to eliminate ice build-up on interior coils.
• Clean dryer filters after each use or as necessary.
