Keen cooks may want to take advantage of multi-function ovens - usually aimed at the top end of the market. As well as traditional cooking, fan or fan-assisted cooking and grilling, these ovens offer up to nine further functions. These include: Top element only (browning), bottom element (final cooking of pastry dishes or pizzas), fan and bottom element (delicate cooking), fan only (thawing).

When shopping for a new clothes dryer, look for one with a moisture sensor that automatically shuts off the machine when your clothes are dry. Not only will this save energy, it will save wear and tear on your clothes caused by over-drying. Keep in mind that gas dryers are less expensive to operate than electric dryers. The cost of drying a typical load of laundry in an electric dryer is 30 to 40 cents compared to 15 to 25 cents in a gas dryer.

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.
