Basically heating and cooling beyond equilibrium temp has a very non-linear costs. You could run whole house AC 100% at 3-5 kw per hour to get your house 6-10 degrees colder at a cost of $400-$1200 per month.
Oh wow, that explains a lot! The energy bills here are fixed and revised only once a year (you may get billed a bit extra at the end of the year if you used a lot), but that makes sense.
