George Goodman discusses the past, present, and future of green IT. The Climate Savers Computing Initiative has made good progress in reducing greenhouse gas emissions from 41-45 million tons per year through improved design and power management practices, but legacy systems and adoption challenges remain. Going forward, green IT must continue improving efficiency and help the majority of organizations and individuals apply its practices to achieve broader sustainability goals through green by IT initiatives that address both IT efficiency and energy sources.

"Green it"
- 1. Past, present, and future of “Green IT” 8 May 2012 George O. Goodman Executive Director Climate Savers Computing Initiative (CSCI)
- 2. Climate Savers Computing Initiative Mission: Reduce GHG from using ICT Industry Work Groups Goals + Best Practices Visibility
- 3. Original CSCI 2007 goal: 54M tons avoided per year by July 2011. So far: Good progress, design and use practices understood, legacy systems and adoption remain challenges Actual: 41-45M tons per year 1. Economic Downturn 2. Power Management Use
- 4. Green IT So far: Then: 50-70% Now: 80-93% efficient Then: <10% Now: ~25% power mgmt use Now: Beginnings of non-use phase action
- 5. So far…in “the Cloud”
- 6. Improvements must continue in efficiency of use Next: Help “the 98%” Apply Green IT to achieve “Green by IT” and address energy sources.
- 7. Global CO2 Emissions ICT 2% 98% Source: The Climate Group Green by IT Green IT
- 8. YOU NEED A SMART SOCIETY TO HAVE A SUSTAINABLE SOCIETY If consumption trends continue, we will need two Earths to support us Smart behaviors get us here Source: Global Footprint Network
- 9. Green by IT uses Green IT to improve efficiency of the other 98%
- 10. Thank you!

- Our accomplishments thus far: Original goal of reducing IT GHG emissions by 54M tons per year Actual realized 41-45M tons – will discuss this in more detail when George presents our 2011 Accomplishments Original goal of improving the energy-efficiency of IT equipment Actual: Desktop PCs in 2007 only ~70% efficient Desktop PCs in 2011 ~90% efficient Servers in 2007 only ~50% efficient Servers in 2011 85-93% efficient Original goal to push toward 100% adoption of power management on desktop and laptop PCs Actual: In 2007 <10% of commercial systems used power management (EPA ENERGY STAR & LBNL) In 2011 20-25% of commercial systems use power management (EPA workgroup estimate)
- Actual GHG results estimated through update to 2010 Natural Logic study, incorporating PC/Laptop/Server sales from analyst inputs + LBNL/ENERGY STAR + Public sources (e.g., OEMs). Carbon per KWh based on equivalency data from US DoE, The Carbon Trust, and public sources for other regions. Actual Power Management adoption estimate from US EPA, LBNL, and CSCI workgroup based on multiple sources including CSCI’s member survey.
- Consumer: initially greater price on more efficient systems, now default AND computer cost lower than 10 years ago Consumer: Good news – easier-to-use varieties (smart phones, tablets, …) & Bad news – increasing number of devices can drive energy, material use, end-of-life recovery challenges, …
- This slide courtesy of Lorie Wigle, General Manager of EcoTechnology at Intel Corporation and President of Climate Savers Computing Initiative http://www.footprintnetwork.org/en/index.php/GFN/page/world_footprint/ Today humanity uses the equivalent of 1.4 planets to provide the resources we use and absorb our waste. This means it now takes the Earth one year and five months to regenerate what we use in a year. Moderate UN scenarios suggest that if current population and consumption trends continue, by the middle of the next decade we will need the equivalent of two Earths to support us.
- Examples of Green by IT: Home Energy Monitoring and Control “ The Smart Grid” Traffic Control and Intervehicle Coordination Electric Cars: IT within the car, also coordination of charge and potential source to grid Wind turbines: IT to control the turbines (10s of processors per turbine & tower) and wind prediction + realtime adjustment Finally, IT to support the realistic, practical use of Life Cycle Analysis to track and reduce carbon and toxics throughout a product’s life, death, and rebirth
