Jan, Feb Mar 2010 warmest ever This is despite a solar sun spot minimum

Climate Forecasts MIT MIT report predicts median temperature forecast of 5.2 ° C 11 ° C increase in Northern Canada & Europe http://globalchange.mit.edu/pubs/abstract.php?publication_id=990 Last Ice age average global temperature was 5-6 ° C cooler than today Most of Canada & Europe was under 2-3 km ice With BAU we are talking about 5-6 ° C change in temperature in the opposite direction in less than 80 Years

Climate Change is not reversible Climate Change is not like acid rain or ozone destruction where environment will quickly return to normal once source of pollution is removed GHG emissions will stay in the atmosphere for thousands of years and continue to accumulate Planet will continue to warm up even if we drastically reduce emissions All we hope to achieve is to slow down the rapid rate of climate change Weaver et al., GRL (2007)

Climate tipping points USGS report finds that future climate shifts have been underestimated and warns of debilitating abrupt shift in climate that would be devastating. Tipping elements in the Earth's climate - National Academies of Science “ Society may be lulled into a false sense of security by smooth projections of global change. Our synthesis of present knowledge suggests that a variety of tipping elements could reach their critical point within this century under anthropogenic climate change. “

2009-10 Canada winter 4.2C warmer than average

Urgency of Action “ We’re uncertain about the magnitude of climate change, which is inevitable, because we’re talking about reaching levels of carbon dioxide in the atmosphere not seen in millions of years. You might think that this uncertainty weakens the case for action, but it actually strengthens it. This risk of catastrophe, rather than the details of cost-benefit calculations, makes the most powerful case for strong climate policy. Current projections of global warming in the absence of action are just too close to the kinds of numbers associated with doomsday scenarios. It would be irresponsible — it’s tempting to say criminally irresponsible — not to step back from what could all too easily turn out to be the edge of a cliff.” Nobel Laureate Paul Krugman http://www.nytimes.com/2010/04/11/magazine/11Economy-t.html?pagewanted=1

The Global ICT Carbon Footprint is Roughly the Same as the Aviation Industry Today www.smart2020.org But ICT Emissions are Growing at 6% Annually! ICT represent 8% of global electricity consumption Projected to grow to as much as 20% of all electrical consumption in the US ( http://uclue.com/index.php?xq=724 ) Future Broadband- Internet alone is expected to consume 5% of all electricity http://www.ee.unimelb.edu.au/people/rst/talks/files/Tucker_Green_Plenary.pdf

The Global ICT Carbon Footprint by Subsector www.smart2020.org The Number of PCs (Desktops and Laptops) Globally is Expected to Increase from 592 Million in 2002 to More Than Four Billion in 2020 Data Centers & Clouds Are Low Hanging Fruit Telecom & Internet fastest growing PCs Are Biggest Problem

IT biggest power draw Heating, Cooling and Ventilation 40-50% Lighting 11% IT Equipment 30-40% Other 6% Sources: BOMA 2006, EIA 2006, AIA 2006 Energy Consumption Typical Building Energy Consumption World Wide Transportation 25% Manufacturing 25% Buildings 50%

Digital vs Traditional appliances

Greenpeace says that the energy consumption of cloud computing in 2007 was 622.6 billion kWh, which is 1.3 times larger than reported by the Smart 2020 report. 50% of today’s Data Centers and major science facilities in the US will have insufficient power and cooling;* By 2010, half of all Data Centers will have to relocate or outsource applications to another facility.* Data centers will consume 12% of electricity in the US by 2020 (TV Telecom) Growth Projections Data Centers & Clouds Source: Gartner; Meeting the DC power and cooling challenge

The Falsehood of Energy Efficiency Most current approaches to reduce carbon footprint are focused on increased energy efficiency of equipment and processes But growth in ICT deployment of equipment and services is outstripping any gains made in efficiency Which is likely to accelerate as ICT is used to support abatement in other fields such as smart homes, smart buildings, smart grids etc Also greater efficiency can paradoxically increase energy consumption by reducing overall cost service and therefore stimulates demand Khazzoom-Brookes postulate (aka Jevons paradox - not to be confused with rebound effect) In last Energy crisis in 1973 Congress passed first energy efficiency laws (CAFÉ) which mandate minimum mileage for cars, home insulation and appliances Net effect was to reduce cost of driving car, heating or cooling home, and electricity required for appliances Consumer response was to drive further, buy bigger homes and appliances The issue is not the amount of energy that we use, but the type of energy

Zero Carbon strategy essential Zero carbon strategy using renewable energy critically important if governments mandate carbon neutrality, or if there is a climate catastrophe With a zero carbon strategy growth in demand for ICT services will not effect GHG emissions Anything times zero is always zero Wind and solar power are most likely candidates because of opportunity cost/benefit analysis especially time to deploy Nuclear has high opportunity cost because of time to deploy http://climateprogress.org/2008/12/14/stanford-study-part-1-wind-solar-baseload-easily-beat-nuclear-and-they-all-best-clean-coal/ But renewable energy sites are usually located far from cities and electrical distribution systems are not designed to carry load http://www.americanprogress.org/issues/2008/12/pdf/renewable_transmission.pdf

Purchasing green power locally is expensive with significant transmission line losses Demand for green power within cities expected to grow dramatically ICT facilities DON’T NEED TO BE LOCATED IN CITIES -Cooling also a major problem in cities But most renewable energy sites are very remote and impractical to connect to electrical grid. Can be easily reached by an optical network Provide independence from electrical utility and high costs in wheeling power Savings in transmission line losses (up to 15%) alone, plus carbon offsets can pay for moving ICT facilities to renewable energy site ICT is only industry ideally suited to relocate to renewable energy sites Also ideal for business continuity in event of climate catastrophe Get off the Grid!

Bill 44-2007 was introduced in 2007 and enacted into law in 2008. The law is known as the Greenhouse Gas Reductions Target Act. The Act establishes greenhouse gas emission target levels for the Province. 2020 BC GHG will be 33% less than 2007. 2050 BC GHG will be 80% less than 2007. Bill mandates that by 2010 each public sector organization must be carbon neutral. If a public sector organization can not achieve carbon neutrality then they are required to purchase offsets at $24/ton GHG Regulation in British Columbia SOURCE: “Greenhouse Gas Inventory Report 2007”, Ministry of Environment, Victoria, British Columbia, July 2009 Source: Jerry Sheehan UCSD

Zero Carbon Data Center source: Dan Gillard BCnet 04/09 BC’s Green Data Centre MUST be in Proximity to a Clean Source of Power

MIT to build zero carbon data center in Holyoke MA The data center will be managed and funded by the four main partners in the facility: the Massachusetts Institute of Technology , Cisco Systems , the University of Massachusetts and EMC . It will be a high-performance computing environment that will help expand the research and development capabilities of the companies and schools in Holyoke http://www.greenercomputing.com/news/2009/06/11/cisco-emc-team-mit-launch-100m-green-data-center

Proposed new funding scenario for R&E networks and cost reduction for universities Many universities are proposing to go carbon neutral and/or mandated to reduce their energy and carbon footprint Purchase of high quality offsets difficult and costly Better to find energy and carbon savings internally Computers, networks and data centers account for 30-50% of energy consumption on campus Video conferencing, eLearning, zero carbon data centers, clouds, grids collaborative cyber-infrastructure, etc should reduce energy consumption Most universities don’t have processes to allocate energy or CO2 costs to individual departments or researchers Significant challenge as appropriating heating, cooling, electricity, computing and networks costs can be very difficult There is no incentive for researchers or educators to adopt low energy or CO2 solutions

Most R&E networks charge a membership fee or base fee based on size of institution, research dollars or number of students Instead propose to charge membership or base fee based on institution’s energy consumption E.g. 1% of total Kwh for the past year R&E network agrees to provide a variety of services at no charge including “ X” miles of dedicated wavelengths “ Y” Mbps of Internet bandwidth “ Z” hours of video- conference “ W” time on a commercial compute cloud or central storage etc Institution is encouraged to reduce energy consumption and there is penalty in services if they do so New R&E network funding scenario “ Cap and Reward”

GreenStar –Clouds and Virtualization Distributed computing architectures, applications, grids, clouds, Web services, virtualization, dematerialization, remote instrumentation and sensors, etc. Share infrastructure & maximize lower cost power by “following wind & sun” networks.

Evolving Internet & Impact on GHG Van Jacobson predicted several years ago evolution away from “end-to-end” Internet to information Internet http://video.google.com/videoplay?docid=-6972678839686672840# Current Internet is based on old telco architecture of connecting users New Internet is based on connecting users to information Arbor study has vindicated Van Jacobson prediction C. Labovitz, et al "ATLAS Internet Observatory 2009 Annual Report" http://www.nanog.org/meetings/nanog47/presentations/Monday/Labovitz_ObserveReport_N47_Mon.pdf Over 50% of Internet traffic is from handful of information suppliers such as Google, Akamai, Content Distribution networks etc Will have major impact on wireless networks as we move from “end to end” cell phone network to cell phone Internet

Traditional Internet Backbone ISP1 Backbone ISP 3 Backbone ISP 2 IX IX Regional ISP Large Content Provider with multiple servers Small Content Provider Last mile ISP Last mile ISP User’s Computer User’s Computer Thousands of miles Fiber Networks

Information Internet – zero carbon Backbone ISP1 Backbone ISP 3 Backbone ISP 2 IX IX Regional ISP Large Content Provider Small Content Provider Last mile ISP Last mile ISP User’s Computer User’s Computer Cloud CDN Content hosted in ACI Nearby

New Internet Increasingly most connections will be local to nearest IX where user will connect to cloud, CDN or social network Connections to another user or computer at the edge of the cloud will be less common Network topologies and architectures will be driven by application and content rather than connecting users “end-to-end” Cyber-infrastructure and UCLP were forerunners of these development Future wireless networks are likely to also evolve in this manner Don’t need an end to end network for accessing applications and content User white space and wifi to provide data to cell phones Next network neutrality battleground will be “last inch” – open devices and “last tower” - Much easier to deploy zero carbon Internet CDN, clouds and social network infrastructure can be built along GSN model Users will increasingly use solar powered iPhone, iPad to access information and applications

Grand Challenge – Building robust ICT services using renewable energy only 30% of electrical power will come from renewable sources How do you provide mission critical ICT services when energy source is unreliable? Ebbing wind or setting sun Back up diesel and batteries are not an option because they are not zero carbon and power outages can last for days or weeks Need new network architectures and business models to ensure reliable service delivery by quickly moving compute jobs and data sets around the world to sites that have available power Will require high bandwidth networks and routing architectures to quickly move jobs and data sets from site to site

WiFi leadership Finally, Wi-Fi has technology leadership. 4G leverages orthogonal frequency division multiplexing and multiple input multiple output, aka MIMO. But Wi-Fi adopted OFDM in versions 802.11a (in 1999) and 802.11g (in 2003), allowing Wi-Fi to achieve 54mbps operation. And Wi-Fi adopted MIMO with 802.11n (draft in 2007). Today, 11n devices ship in high volumes, use 2.4gHz or 5gHz spectrum and provide 100-300mbps. New Wi-Fi silicon will deliver as much as 600mbps, and beamforming antennas will increase range and allow dramatically more wireless connections in the same area. As consumer devices with access to more spectrum than either WiMAX or LTE, Wi-Fi can deliver more megabits per second per dollar. Expect to see both fixed and mobile carriers including free Wi-Fi access in their subscription bundles as Wi-Fi trumps femtocells. Conventional operators are not going away but, over the next decade, its Wi-Fi that will shake up business models and drive disruption 802.21 is an IEEE emerging standard. The standard supports algorithms enabling seamless handover between networks of the same type as well as handover between different network types also called Media independent handover (MIH) or vertical handover. The standard provides information to allow handing over to and from cellular, GSM, GPRS, WiFi, Bluetooth, 802.11 and 802.16 networks through different handover mechanisms. 802.21 Will Allow roaming between 802.11 networks and 3G cellular networks. A cellular phone user in the midst of a call should be able to enter an 802.11 network hotspot and be seamlessly handed off from a GSM network to the 802.11 network and back again when leaving the hotspot. IEEE 802.11u is a proposed amendment to the IEEE 802.11-2007 standard to add features that improve interworking with external networks. IEEE 802.11 currently makes an assumption that a user is pre-authorized to use the network. IEEE 802.11u covers the cases where user is not pre-authorized. A network will be able to allow access based on the user's relationship with an external network (e.g.hotspot roaming agreements), or indicate that online enrollment is possible, or allow access to a strictly limited set of services such as emergency services (client to authority and authority to client.)

Free Wifi on Buses There’s a school bus service called The Green Bus in Birmingham, UK which operates double-decker, low-carbon emissions buses that carry over 1400 kids to school every day (saving over 2000 car journeys). In addition to encouraging kids to play peer-to-peer games, the access points allow the bus company to monitor where the buses are in the city in real time. Parents as well as staff can follow the progress of any bus via Google maps. Business bus service in San Francisco offers office on the move – free wifi, femto cell service etc http://www.muniwireless.com/2009/01/14/school-kids-enjoy-wi-fi-on-green-bus/ 32

Carbon Reward Strategy for last mile infrastructure Provide free high speed Internet and fiber to the home with resale of electrical and gas power (ESCOs) http://www.newamerica.net/files/HomesWithTails_wu_slater.pdf Pilots in Cleveland, Switzerland, Ottawa, etc Customer pays a premium on their gas and electric bill Customers encouraged to save money through reduced energy consumption and reduced carbon output Customer NOT penalized if they reduce energy consumption May end up paying substantially less then they do now for gas + electricity + broadband + telephone + cable Network operator gets guaranteed revenue based on energy consumption rather than fickle triple play

Final remarks The problem we face is NOT energy consumption, but carbon emissions Think carbon, not energy We must start addressing climate change now – not in 2050 or 2020 80% reduction in CO2 emissions will fundamentally change everything we do including universities and networks Huge potential for innovation for ICT sector because 30% of energy must come from renewable sources
