NOTHING but cheap!

I only have a patio villa (the smallest home), but it is currently rented year round and I see the monthly bills. It's all electric and I've never seen a bill over $90.00 which would be the hottest months. Last month it came in as only $47.00. Now that's NOTHING but music to my ears! My cousins both have large expanded designer homes, all electric, and their bills have never been more than $150 in the hottest months.
