      All,

      Our house was built back in 1998. It has more or less typical energy features and appliances. The following is a list of measurements that I took with the WattsUp meter of each device over a period of time.

      This comes from a text file and may unformat itself on Yahoo. If you want an original copy, just ask and I'll email one to you.
