Household Bills & Utilities SUPER Expensive?

What lot traits do you have? There are a couple that help with water and energy. I don't have any dew collectors on my lot in Oasis Springs, but I have the Natural Well and Geothermal lot traits, so even in a household with 6 sims, a cat, and a pool, I usually have water to sell back. Power tends to be less than $100. I do, however, have a ton of flowers and collectibles. My base bills are around 25K, but I've also got the nap that gives you a discount if you've got a bee box or bug box and a planter (both of which I have) and I use the floors and walls from Eco Lifestyle in many of the rooms, so that also gives a discount. (And I have a solar roof because I like the idea and wish I could have one in real life. And I like the look pretty well too.)
