The best way I found to reduce you energy use is simply to know exactly what items use ( I ended up writing a program to keep track & calculate costs for me).By knowing what's worth turning off, you can save without loosing you lifestyle.
I found , like Gordon, some devices using abnormally larger amounts of power on standby, Mainly the A/C (105W standby) and a Sony stereo (40W standby) both hardly get used so their off at the switch now.
I started of using a simple $17 plug in type energy meter and a mates clip-on multimeter(for the A/C,Stove etc).
The only 'Energy saving' device I use Is Master/Slave Powerboard on the TV (to turn the set-top box,PlayStation,stereo,DVD on and off)saved around 35-40W on standby
My last bill was around $950 (without solar) the next one should be around $350(without solar) , just from checking each item out.(I have in the past had a couple of "Energy Audits" done, none saved me a cent, some even gave very questionable advice)
Every watt you don't use, is a watt you don't have to generate or pay for.

, there's also a "meters" page on different types of meters
