Feeling Ripped Off

I am feeling a bit ripped off today.  I just don't understand how our electric bill can go up so much from last year???  A friend of mine was feeling the same way the other day...

Last year we used 830 kilowatt hours and this year we used 1278...now how can it be that much higher with an average daily temperature only 1 degree higher than last year???

We have switched our electronics to a power switch...so we don't have phantom electric usage.  I know there are the two fridges, the washer/dryer...kids leaving their lights on and we are using fans a lot, but we use them a lot last year.  My husband hasn't really worked here to use electricity like some summers.  What is causing our high usage???

I am thinking more and more that we need to bite it and blow in insulation into our attic.  My hubby isn't looking forward to that as we have vaulted ceilings and he will have to crawl in...but is that one of the solutions?  Our windows are fairly new, but we could use some better energy efficient doors.  I just can't see how it can be higher if we really aren't doing much different from last year???

What do you do to keep your electric costs down?
