In this paper the data life cycle management is extended by accounting for energy consumption during the life cycle of files. Information about the energy consumption of data not only allows to account for the correct costs of its life cycle, but also provides a feedback to the user and administrator, and improves awareness of the energy consumption of file I/O. Ideas to realize a storage landscape which determines the energy consumption for maintaining and accessing each file are discussed. We propose to add new extended attributes to file metadata which enable to compute the energy consumed during the life cycle of each file.
