The "Green Tip of the Week," from the U.S. Environmental Protection Agency and Penn College's Energy Conservation Subcommittee, takes a peek at the holiday list that Mother Earth has worked up this year. It includes recycling leftover gift wrapping, giving energy-efficient products and finding a better way to Grandma's house. Think green and clean! (Contacts for this feature are Gail B. Landers , group leader at the Children's Learning Center and a subcommittee member, and Carl J. Bower Jr. , horticulture instructor.)
