Electricity and water DO vary a lot between cities and towns here in TN. But then, so do the circumstances that go along with utilities and other cost of living.
When I lived in Greeneville I was paying about $100 a month in electricity, $20 a month in water but had to buy fuel oil for the furnace which was about $1.40 a gallon (back in 2000-2005) and had to buy about 800 gallons a winter, no AC. I had no garbage pick up, had to bring trash to the "convenience center". (dumpsters in a fenced in area.) Property tax was $128 a year. (nope, not a typo

)
Then I moved to Washington County, N.Johnson City. For about the same square footage house with a heat pump verses a furnace: Electricity $225, water/sewage/trash pick up at the house $113 a month, property tax $528 a year.
Difference: Greeneville, I had to drive over 15 miles into town for groceries, hardware and such. No work so had to drive 50 plus miles each way for work.
Johnson City, less than 8 miles for grocery and hardware, work less than 20 miles.
So yea, I pay a bit more in property taxes (but still supper low!) and a bit more in electricity, lots more for water, but a whole lot less in gas, which can really add up. Not to mention the wear and tear on the car. Plus I spend a lot less time commuting and more with the family, which is much more important than money in my opinion.
I bought a car in 2004 when I lived in Greeneville and worked in JC. First year I put 25k miles on it just driving back and forth to work or to shop. Moved to JC in 2005. Since 2006 I have put 10k-15k miles a year on it, but then again, I do a lot more than just driving back and forth to an office now, I do a lot of driving for work, but still.
