This has a big impact on appliances that run throughout the day, like air conditioning units, fridges and freezers. Making sure your units are maintained and running as efficiently as possible will reduce the total energy required to power these units.
Your geyser is most probably set at around 75℃. Lowering this temperature to 55℃ will save you money, but still, keep your water hot.
Hot water geysers use a lot of energy to heat up and maintain their temperature throughout the day. Installing a timer on your geyser to heat up 30mins before use is one of the best ways to save electricity.
Your geyser is without a doubt one of the biggest energy consumers. That means keeping your geyser insulated will help it maintain the temperature which means less electricity is consumed between ‘cool down’ periods.
There are all sorts of light bulb options these days, but the best one (from an energy conservation standpoint) is LED. You can save over 90% of your electricity by switching certain lights to their LED replacements. Not only that but LED lights also last longer and usually only need replacing once every 4 years.
