We’ve all left the house with the fan still running, fridge door ajar, or mains switched on by mistake. But instead of kicking ourselves over these slip-ups, a closer look at the power needs of each of our home appliances might help us focus on the most effective ways toreduce our electricity consumption.
To help make the biggest dent in your monthly bills, we’ve sussed out home appliances with the highest electrical consumption. From power-guzzling water heaters to refrigerators that sip on electricity 24/7, you’ll want to pay extra attention to these key appliances – whether you’re kitting out your new BTO, upgrading, or planning for maintenance for the long haul.
Note: At the time of publishing, the price of electricity is $0.25 per kilowatt-hour (kWh). The wattages listed are based on the most popular models of each appliance in Singapore.
In tropical Singapore, it might be tempting to reach for theairconremote the moment you reach home, but keeping your bedroom nippy might be that constant hole in your wallet. It takes plenty of power – 2,000 watts – to maintain the extra-shiok cool air, and even if you’re only using it for the eight hours you’re snoozing at night, this quickly adds up to $4/day.
Average hours used per day:Eight hoursTotal cost per year:$1,460
How to cut consumption:For households that regularly rely on it, air conditioning is hands-down the largest contributor to energy wastage. But while opting for alternatives like fans can help score massive savings, you can also check out bonus tips to keep your HDB cool throughout the day.
Otherwise, if you die-die cannot sleep without this Singaporean essential, opting for a more efficient 5-tick model can save you up to $270 per year over a 2-tick unit. Maintaining a temperature of 25ºC and scheduling aircon maintenance twice a year can also save you money in the long run.
Visiting an onsen in Japan or soaking in a sauna might be a luxury, so it’s little wonder that most of us yearn for a steamy, hot shower to unwind and relax – especially after a long day. While you might not spend much time in the shower each day, this ritual might still be setting you back a sizable sum aswater heaterscan consume around 3,000 watts – 50% more than aircon units.

One of the most important appliances in the kitchen, ourfridgesare our go-to for everything from fresh milk in the mornings to frozen suppers late at night. Though most fridges only consume a paltry 180 watts, these must-have appliances are plugged in round the clock and can drain power over long periods of time.
Average hours used per day:24 hoursTotal cost per year:$400
How to cut consumption:For an appliance that’s left running for years on end, opting for the most efficient model will go a long way in helping you save on your bills. In general, picking the smallest practical fridge size for your household can help reduce energy usage. Top-mount freezers are also more efficient as they keep the hot condenser unit at the bottom of the fridge well away from the super-cold freezer.

We’ve all been told that we should reduce laundry sessions to save on water consumption, but this can also help to save on your electricity bill. For the average Singaporean household’s 7-litre, 2,000-wattwashing machine, each session will consume a solid $2 worth of electricity.
Average hours used per day:One hourTotal cost per year:$183
How to cut consumption:Selecting front-load washing machines can help reduce both water and electricity. And while you aim for full loads for each laundry cycle, you’ll want to ensure that you don’t overload your washer – as that can be inefficient and cause wear-and-tear over the years.

For those of us lucky enough to WFH on the regular, ourcomputersmight be one of the largest reasons you’ve been seeing slightly higher figures in the mail each month. Desktops and gaming PCs can consume up to 500 watts, which can add up especially if you’re constantly OT-ing or if you love kicking back after hours for Netflix or a few rounds of Valorant.
Average hours used per day:10 hoursTotal cost per year:$183 per computer
How to cut consumption:Like most electrical appliances, computers consume different amounts of power depending on how much is required – gaming marathons in 4K are a much larger drain on power as compared to casual browsing on your favourite sites.
Apart from keeping your gaming hours in check, you might also want to opt for more power-efficient laptops like ultrabooks and MacBooks – which mostly only consume about 90 watts, tops.

Average hours used per day:Eight hoursTotal cost per year:$51 per fan
How to cut consumption:If there are multiple people in a single room, using ceiling fans can help keep everyone cool without having several fans to do the job.
