My electrical bill only RM 40-50 per month with about 500L fidge(Inverter), 1 hp Air corn (Inverter) using only 6 hour daily with setting tempeture 25 celcius, all saving energy light, washing machine and other. Normal use after office hour and some time weekend go to my mother house. 4 people in the house. Digital TNB meter. so electricity usage always depend on our attitude when using electricity.

yup setting temp at 25 is the simplest way to save electricity since i have read somewhere that reducing ac temp 1 celcius will increase electricity usage 10-30%. so lower the ac temp u can expect higher electricity bill.
