Interestingly, in the mid 90s, the average NSW household used 4000KWh per year, now it averages 7500KWh per year, so I reckon we could all cut back a bit.
My power bill for the last 12 months was just over 3000KWh, and I could still trim that by 10% or more if I was a bit more vigilant.
The Garnaut report from last year makes some interesting points on real pricing compared to 1980s levels.
