3$ a week(average) extra for electricty... nice starter... how far can we bend

Not sure where you got that from, but in my household , av daily spend will increase from $5.50 to around $6.65 (assuming  20% price  increase) , so thats about $8 per week .
We are using about 25Kwh per day which far as I know is moderate use compared to the average ?

Don't know about bending , a think a lot of people were already on the edge before this stupidity kicked in
