According to the latest Singapore Household Consumption Survey, air-conditioners are the highest energy-consuming appliance in the home -- they take up more than one-third of your household energy consumption.
To put things in perspective, one air-conditioner can power approximately 11 fans. Just setting the timer to turn off the air conditioner half and hour than usual saves you $30 a year; every degree higher your air-conditioner is set at saves you $15 a year; and using a fan can save you S$460 a year in electricity bills.

KNOW YOUR ENERGY LEVELS
You can estimate much energy by doing a Home Energy Audit via the myENV app. While it only presents the energy consumption in the amount to be paid, it's a good enough estimate. (Would anyone have a better app to recommend?) What I especially like about the myENV app, however, is that it also offers tips and alternatives on how to save energy.

HOME AUTOMATION CAN HELP
I'm guilty of sometimes forgetting to switch the lights off when I go to bed. Apple’s Homekit (a home automation platform) can help schedule a time to switch the smart lights off. We've got friends who program the Homekit so their lights turn on when they are approaching home, and off when they leave -- two less things on the list of things to do.
For those who keep the light on at night to prevent falls and injuries, you can install a wireless motion sensor.
Water heaters are the second biggest consumer of energy in a typical Singaporean household -- they take up more than one-fifth of your household energy consumption. That's as good an excuse as any to take more cold showers.
