The EnergyGuide label on new refrigerators will tell you how much electricity in kilowatt-hours (kWh) a particular model uses in one year. The smaller the number, the less energy the refrigerator uses and the less it will cost you to operate. In addition to the EnergyGuide label, don't forget to look for the Energy Star label. A new refrigerator with an Energy Star label will save you between $35 and $70 a year compared to the models designed 15 years ago. This adds up to between $525 and $1,050 during the average 15-year life of the unit.

This is a big ticket item, but worth its weight in gold. It will save so much time when it comes to simple chopping or more advanced preparations like mayonnaise. As with most things, buy quality-- it will last longer, be capable of tougher jobs, and give you less problems. To make the food processor easiest to use, leave it on the counter top instead of storing it in a cabinet.

Energy efficiency is of paramount importance, not only to save money on electricity bills but also to help reduce power station emissions that contribute to global warming. Look for brands with low energy consumption (energy efficiency ratings will be displayed in the showroom). Levels are now as low as 1.3kW/hr on some slimline models largely because of reduced water consumption. A delay timer can help take advantage of cheap overnight electricity.
