Energy costs have become the dominant factor in IT infrastructure total cost of ownership (TCO), with data centre operators predicted to spend more money on energy than hardware infrastructure in the next five years. With Western European data centre power consumption estimated at 56 TWh/year in 2007 and projected to double by 2020, the need to improve energy efficiency of IT operations is imperative. The issue is compounded further by social factors and strict environmental legislation. In this presentation we introduce the key issues and motivations behind green IT before presenting a novel approach to energy-efficient content distribution using the BitTorrent peer-to-peer protocol to minimise energy consumption and reduce operational costs.
