Household electricity consumers often find themselves surprised by unexpectedly high monthly bills, struggling to pinpoint exactly where the excess energy is being utilised.
Experts and industry insiders suggest that several common household appliances and improper usage habits are the primary drivers of these rising costs.
Temperature control and positioning
Air conditioners and room heaters, essential for maintaining comfort during summer and winter, are typically the highest energy consumers in a home. However, their placement and settings can further inflate costs.
If devices are positioned where they are exposed to direct hot air or air entry paths, it results in incorrect temperature readings. Consequently, the unit operates for longer than necessary to regulate the room’s temperature.
Inefficient old refrigerators
The continued use of old refrigerators is another significant factor. Appliances older than 15 years can be significant sources of power consumption. An aged refrigerator can consume approximately one thousand units of electricity annually because the insulation becomes weak and the compressor is no longer as effective.
‘Vampire’ power draw
A common misconception is that appliances do not consume power when switched off. Devices that operate via remote control, feature screens, or use adapters continue to draw a small amount of electricity even when not in active use.
This includes televisions, gaming consoles, computer and mobile chargers, cable boxes, and kitchen appliances such as microwaves or coffee makers. Experts recommend unplugging these devices or turning off the main switch as the simplest solution.
Impact of dirty air filters
Maintenance of air filters is equally critical for energy efficiency in temperature-controlled rooms. Dust accumulation can block filters, forcing the appliance to work harder than usual. This can increase electricity bills by 10 to 20 per cent in most households.
