let's talk about how to save water bill or electricity bill.
I have some idea about how to save electricity bill.
1) install turbine fans on the roof
2) keep upstair AC always off and move children downstair
3) turn on downstair AC at destinated time, for example 15:00 to 24:00
can someone share his or her idea about how to save water bill?
