Utility Madness - Foreigner's Tax

Some people had been wondering whether we were paying a special rich-foreigner tax for our utilities because of where we live. I asked some locals at work how much they were paying for utilities and they gave numbers that were within range of my numbers. So, it seems that energy is quite expensive for local Chinese folks since it is approximately the same converted price as in the United States.
If and when the Yuan is revalued even more than it curently is, I wonder if these costs will go down. You can't very well keep the prices this high if the value of the Yuan increases relative to the dollar, can you?
