Was on Nate Berkus show today...
 
To save water: $86 a year for family of 4
 
Take a plastic bottle, looked like a 1 litre bottle, not a 2 litre bottle....fill it half way with stones or sand , put the bottle cap on and put one  in each toilet tank.....(Think dad used bricks)......will save water on each flush.
 
The top energy user is a: refrigerator,
 2nd is a  clothes dryer.  DON'T let the dryer run when the beeper goes off...Uses so much electricity....beeper goes off,,,,shut the dryer off...................
.Air dry when possible, especially in the summer.
 
Things not used but plugged in............pull the plug until you need it.
