My $105 bill is pretty good for south Texas in July :)
In the fall and spring (when A/C and heating isn't necesary) it's more like $50.

Our house is all-electric (dryer, stove, hot water heater) and yes, we run the A/C (though not at a refrigerator-cold setting).

I've made myself a sort-of expert on energy savings though :) I know how much each appliance costs, etc.

I use all compact-flourescent bulbs (the curly light bulbs) which use 1/4 as much power, and LCD monitors for my computers, etc. We certainly turn things off when they're not being used. And we don't have a TV, that helps.

And the biggest way to save energy? Turn off things when they're not used! Anyone who tells you otherwise is LYING TO YOU. That goes for computers, TVs, air conditioning, heating, fans, lights, etc. The savings starts when you switch them off. There's no "mega power drain" when something is first turned on -- that's absolutely ridiculous and nothing but a big myth.

There's a great site on the web called "Mr. Electricity". He bangs his head on the wall all the time, because he has to hear all the stupid things people believe. "I have a fixture with 2 light bulbs. If I take one of them out, will it still use the same electricity?" and similar dumb questions.

Anyhow, he explains it all very well. He wasn't my only source though -- I read everything I can get my hands on when it comes to this topic.
