Cost of Using Appliances

Household appliances such as refrigerators, deep freezers, air conditioners and TV have become an integral part of modern life. The power rating of most of these equipment is not high but misuse could lead to energy waste.

Computers, printers and typewriters used in offices also have low energy rating. However, if left on when not in use for a long time, could lead to high energy consumption. Switch them off when you are not using them.

The electrical cooker is the highest electrical energy consumer in the home with a power rating of about 8500 watts. Unless it is inevitable, avoid using the electric cooker. The gas cooker is a cheaper alternative.

The cost for using electric appliances is calculated for consumers with a total consumption of up to 300 units/month (583 Cedis/kWh) as well as for households exceeding the 300 units/month (1018 Cedis/kWh).

Change to Compact Fluorescent Lamps (CFLs) and safe 80 % electricity used for lighting!

CFLs can be the best things to happen to your home because CFLs save energy, last a long time, are environmentally friendly and have a cool operating temperature so they don't heat your house. Unfortunately, many people are discouraged from buying CFLs due to the price.

CFLs are more expensive because they have many more components, use special materials, and are much harder to manufacture than incandescent lamps. Even though CFLs are more expensive in the store than incandescents, they will save you money. CFLs use 1/5 the energy of an incandescent and last seven times longer. So over the life of the lamp a CFL will pay for itself because of lowered energy bills and less frequent replacement costs.

The comparison is based on 12 hour use per day. 1 kWh = 583 Cedis.

Energy Saving Tips
Most important of all read your electricity meter regularly and set targets to reduce electricity consumption.
Television, VCR and HiFi
Switch off your TV, Video and Hi-Fi at the set or at the plug. Appliances in the "Standby" mode can use as much as 10-40 % of the electricity that they would use during normal operation.
Fridges and freezers
Defrost fridges and freezers regularly to keep them running efficiently. Don't put hot or warm food straight into the fridge or freezer. Let it cool down first. Position your fridge or freezer always from cookers or sources of heat and about 20 cm from walls to allow ventilation of the cooling fins behind the appliance. Don't open fridge or freezer unnecessarily.
Airconditioning units
Switch off ACs when you are going out of the room for long periods (10 minutes or more). Service all ACs regularly to keep them running efficiently. Keep doors and windows shut when AC is in operation. Shade all windows exposed to the sun, where possible.
Ironing
Iron clothing in bulk and not in small quantities at a time. Ensure that the thermostat on the iron is working and set the right temperature for the clothing being ironed.

Cooking
Use a cooking pan that is slightly bigger than your cooker plate, coil or burner. Keep saucepan lids on. Turn down the heat once food starts boiling.
