Here is some tips for saving electricity:
1.Use inverter for your fridge, not your aircon!
2.Wash as much clothes as possible per cycle when you use washing machine
3.Use iRobot vacuum cleaner instead of airbag/filter/water-base vacuum cleaner! The cost can be $3 vs $30!!!
4.Use good quality water filter instead of boiling water!
But still needs to boil the water for coffee or tea la. Don't waste a money on useless or pretentious filter unless you want a complete RO system
5.Try not to bathe late at night so you can skip the water heater!
Are you meant taking a shower unless you have a bathtub. I always take a cold shower regardless of day and night.
6.Buy/rent a high floor house that has big wind everyday! eg, Redhill opp MRT/Marine Parade facing the sea
7.Get a short and neat hair cut so you can throw away your air dryer!

8.Steal electricity outside of your house

9.and the list goes on......
