How can you tell if a house you are thinking about buying is energy efficient? Need some ideas about reducing the energy used for hot water? Can a range hood save energy? Answers to these three questions and more are covered in current newspaper columns written by Ken Sheinkopf for the McClatchy-Tribune News Service. The home buying topic appeared in the Detroit Free Press, the hot water column appeared in the Bradenton Herald, and the range hood got a nod in the Chicago Tribune. All three columns are interesting and could help you save energy and money.
