I am in the process of changing all the lightbulbs in my house to compact florescent. I am wondering how much energy I can really expect to save by doing that. Do you think I would really notice any change in my electric bill, or is it more that I am just doing something to help reduce carbon emissions?

This is a challenge posting by CNChallenger.

Yes you can save. Some don't like the color temperature (color). There are even more efficient led bulbs.

The math is simple enough if you have accurate data on your current usage. For example, if you replaced 10 60W incandescent bulbs which are on 6 hours per day with 10 of the 13W CF equivalent bulbs, then over a 30 day electric bill you'd see:
10 x 60w x 6hr x 30days = 108kWh
10 x 13W x 6hr x 30days = 23.4kWh
Electricity savings of: 84.6kWh
If your paying $0.10 per kWh for your electricity, then you would see an $8.46 savings on your monthly electric bill.
In terms of "total energy" consumed to provide the same amount of light, it is very important that the CF bulbs last many times longer than the incandescent bulbs because they require a LOT more energy to make.

But, I do not know what this has to do with "digital home" electronics, these are not digital devices.

I was thinking the same thing. However, you have given the O.P. a pretty good answer to his question.

Please let us know if you found someone's advice to be helpful.

Pyro is about right. I changed 14 bulbs from incandescent and the savings was about 10 bucks a month.

Got most free from PG&E and a few (use 'em in lamps that are not on much) at the dollar store.
