To some of the people that have already posted their electric rates, and to those that have not, if you think about it, put the sq footage of your house in your posting so there is a little more information to compare.
We haven't gotten our bill this month yet; it doesn't come until the end of the month. Our June bill was $130 . We have a 2400 sq ft house and keep our A/C on 80 degrees.
Lately, to try and lower the cost, we have been turning off the A/C and opening the windows in the evening when the outside temps have dropped to lower that 80 degrees. We then turn the A/C back on in the morning.
I work for a homebuilder and saw the invoice today for one of our model houses. It was $1001.16.
Our June bill was $123.08 for 987 kilowatt hours used. We live in a 3 story townhome that is just under 2000 sq ft. We have kept our a/c set at 68 for the whole summer so far. Our electric company puts on the bill the kilowatt hours used on a daily basis for the current months bill as well as for that same month the year before. June 2009 we used 33k per day and June 2010 we used 33k per day. They also put the average daily temp. which for this June was 72 and last June it was 67.
Our July bill will probably be higher since we had many days in the 90s and 100s. We save some with living in a middle townhome. We only have windows in the front and back of the home which makes a big difference for cooling and heating. Our home is also insulated well. We lost power one day and the temp. did not go up more than 2-3 degrees in the 4-5 hours it was out. The temp. outside on that day was in the 90s.
) it only jumped up to $170. It has been cooler the last few days and I keep the AC off most of the day so hopefully next month goes down a little bit 

). We have other things we wanted to renovate first, so we just got two window a/c units - one for the bedroom and one for my office as I work from home full time. We use box fans and/or ceiling fans for other rooms. Between the fans and the window units, our highest summer electric bill in the last five years has been $118. Usually it's right around $100. We find that we are comfortable most of the time, the only problem I have is using the kitchen on really hot days, that can be a killer so I try to plan to grill outside on those days, or whine at my DH until he takes me out to eat! 
I'm a stay at home mom with 4 kids, and we find having the a/c at 76 its hot in here. My hubby is gone right now, but he usually keeps it even lower. ha ha. Ours runs pretty much all day long.
. My highest bill then, when the heat is turned on and set at about 72°, is usually about $320. YUCK... I don't even want to think about it.
