I agree with @Sporkasia and this article. You have to change your norm when it comes to ways to save energy. One summer when I was on a tight budget I decided not to use my air conditioning in my house.
The house was a small three room place and it had a ceiling fan in the TV room/bedroom. I had a sofa sleeper. I decided not to use the A/C after I turned it on a few times at the beginning of the summer and then I got my electric bill and it was more than double what I had been paying.
Not using the air wasn't uncomfortable once I got accustomed to not having it. I opened windows and the ceiling fan worked well. I also bought a small floor fan and I was fine. I was even better when the electric bill arrived each month. I was amazed at the difference not running the A/C made.
