Do energy saving bulbs make a difference?

What are people that are unable to see properly with CFL bulbs meant to do. I find for outside use they are fine but for indoor use especially whilst reading they are a complete waste of time and money.
 
Congrats! Thats 50 euro a month. But u will be surprised how much more you will save as you go along. Please keep us posted about your efforts and savings!

I suspect you are reading too much into the estimated versus actual. I find there is NO correlation between the two for me, and estimated can be twice the actual figure. It's not clear how the estimated figure is derived, whether it is based on that addresses previous usage or previous/average usage in that area or for that residence type (apartment, 3 bed, 4 bed etc).
