Jame Dulley

Nationally syndicated columnist who is mechanical engineer that writes about energy efficiency in homes and such.

From his website: "Since moving into this 12-year-old house ten years ago, I have gradually made efficiency and comfort improvements. Even at today's higher utility rates, my monthly bills are over 70% lower than the previous owner's bills. This has been a savings of over $15,000 already."
