Green Computing Challenges • Demand for computing capability only growing => Peta->Exa, Ubiquitous computing, Clouds • Energy cost rivals IT equipment cost • Server energy expense grew 31% over last five years • Challenge to lower power but maintain reliable operations • CMOS scaling limitations • Availability vs Efficiency • Productivity vs Efficiency • Software bloat – modularity for rapid development over efficiency • Loss of insight into physical resource usage • Barriers to new technology adoption • Widespread deployment of and dependence on current technologies • Cost of technology development - fewer players with consolidation? • Challenge to utilize renewable energy sources to power IT • Variability in energy availability and energy storage technology limitations • Inefficiencies in and higher cost of renewable energy production
