Compare apples to apples... how much does it cost a swamp cooler to keep a house at 72F all summer long vs. 72F from an A/C. Oh wait... swampers can't do that... not to mention all the added humidity from a swamp cooler that makes it feel warmer inside than it actually is.
Your 80% savings is like comparing my F-250's fuel mileage while towing to a moped. Sure the scooter is 80% cheaper to operate per mile... but it's not exactly towing 6000 lbs very easily.

You know me better than that...

Same target temp, 1600 foot house 2003 data & energy costs... It is probably at least 10% higher today plus larger sq. feet.
If you want to see more data on the newer 2 stage coolers which add very little humidity and run as low as 1/24th the operating cost of AC over time, go here...

In this climate, the added humidity is actual good compared to the drying affect of AC.
My swamp cooler isn't large enough to really cool this house which is why it gets warm. If it was, it would already be cool enough in here and the extra humidity would not matter.
