Ive taken 1/2 the light globes out and replaced what was left with energy saving type, also turned the hot water system down from 75c to 55c. The kids are limited to how much time they can spend in the shower. try not to use the oven too much and use BBQ where possible. This has made NO difference to my bills what so ever... mine have gone from $300 a quarter to nearly $500 with 7 days to pay once bill is received.
 My wife insisted that we get a big f*ck off  flat screen TV cos it will save on energy...... WRONG!!@!! Once home i compared the massive CRT one that was getting chucked and the new flat screen and the flat screen pulls a further 20W of power.
Interested observation though...

In my shop where i manufacture illuminated signage i have the place absolutely flooded with neon 24/7... most are on high efficiency electronic power supplies. Those that are not are on iron core transformers which are almost a pure inductor... so what they pull they then pretty much throw back down the line on the next AC wave. My biggest energy sucker is the bombarder... pulls 40A at full pelt and delivers 20,000V @ 1A. My bills here are absolutely minimal... laughable in fact.. $200 a quarter.
It would be cheaper for me to run 15mm neon round the whole perimeter of my lounge room, than it would be to have 3 off 40W bulbs... be bloody bright though!!!
