  1. Maximizing Your IT Budget through Energy Efficiency Heather FeigumFocus on Energy Advisor

  2. Agenda • Focus on Energy overview • IT and data center energy growth • Demand and supply energy • Energy efficient computing • Recent IT projects

  3. What is Focus on Energy? Wisconsin utilities’ statewide program for energy efficiency and renewable energy

  4. What is Focus on Energy? • A partnership of all of Wisconsin’s investor- and municipally-owned utilities, as well as about half of all electric cooperatives • One statewide energy efficiency and renewable energy program rather than many, separate programs

  5. What Does Focus on Energy Do? • Helps Wisconsin residents and businesses implement energy-saving projects • Offers unbiased information and technical assistance to participating utilities’ electric and/or natural gas customers • Provides cash incentives for energy-saving projects that would not occur otherwise, or to complete projects sooner than scheduled

  6. Focus on Energy Programs • Residential • Business • Industrial • Commercial • Agricultural • Schools and Government • Renewable Energy • Handled by each sector • Includes biomass, hydro, solar and wind

  7. Focus on Energy Accomplishments Focus on Energy has saved Wisconsin residents and businesses $2.50 for every dollar spent. Overall, Wisconsin residents and businesses save over $319 million annually in energy costs.

  8. Focus on Energy Participation More than 91,000 businesses and 1.7 million residents have participated. More than 3,000 trade allies partner with Focus on Energy.

  9. Focus on Energy Services • Technical assistance • Unbiased expert advice • Industry expertise • Energy evaluations • Network of trade allies • Education and training • Financial incentives

  10. IT System Challenges • Electricity cost and supporting infrastructure is surpassing the capital cost of IT equipment over its useful life • Continuous growth of number of computers and transition from desktop to laptop/tablet • Data Centers are often housed in rooms not originally designed for IT equipment • Heat density is 3-5 times higher than normal office environment Source: U.S. Department of Energy: Energy Efficiency & Renewable Energy, March 2011

  11. Data Centers = Information Factories Data centers are energy-intensive facilities • IT and telecom facilities account for approximately 120 billion kilowatt hours of electricity annually • 3% of all U.S. electricity use • Rapid growth in the U.S. data center industry is projected to require two new large power plants per year just to keep pace with the expected growth in electricity demand • Source: U.S. Department of Energy: Energy Efficiency & Renewable Energy, March 2011

  12. Supply and Demand Energy Source: Emerson Network Power

  13. IT Energy Supply Side Source: Emerson Network Power

  14. Processor Efficiency Challenges • Low power processing vs. high power processing • Idle speeds are approximately the same amount of energy • High power version uses more energy under load (peak processor usage) but operate for shorter amounts of time • Low power processing will use less energy under load but operate for longer duration

  15. 1 for 1 Initiative • 1 computer for each student • Challenges: • Additional energy load • Managing laptops versus desktops • Charging efficiency options: • Lower AC amperage input to charging station to reduce input wattage • Smart AC timers to switch charging on or off during peak hours

  16. CRT to LCD Monitor • 17” CRT uses 75 watts and dissipates 256.5 BTU/hr • 19” LCD uses 24 watts and dissipates 81 BTU/hr • Energy savings = about $10/year in electricity savings per monitor

  17. Efficient Cooling in Data Closet • Precision cooling v. Comfort cooling • Precision = 80-100% cooling and 0-20% dehumidification • Comfort cooling = 60-70% cooling and 30-40% dehumidification • Data center environments require 80-90% sensible cooling ratio for efficient cooling • Cold Aisle Containment • Only direct cooling to the back side of servers – where heat is rejected from

  18. IT Energy-Saving Opportunities IT Electrical Cooling • Power supply efficiency • Standby/sleep power modes • IT equipment fans • Virtualization • Multiuser computing • ENERGY STAR • Air management • Free cooling – air or water • Centralized air handlers • Low pressure drop systems • Cooling plant optimization • Direct liquid cooling • Right sizing/redundancy • Heat recovery UPS, transformer efficiency High voltage distribution DC power use Right sizing/ redundancy Lighting–efficiency and controls

  19. Current IT Incentives • Prescriptive IT incentives • Network power management • Custom IT incentives • Multi-user computing • Energy efficient UPS • Energy efficient cooling • Airflow management

  20. PC Network Case Study: UW-Oshkosh • PCs were kept on 24/7 to accommodate students and complete nightly software updates. • To save energy, the campus used built-in Windows Wake on LAN functions along with EPA’s free power management tool, EZ GPO. • 485 computers put into low-power sleep mode • Continued to perform software updates at night • Saved approximately $20 per PC annually

  21. Financial Analysis • Annual savings in dollars • Simple payback calculation: • net investment/annual savings = payback period • Lifecycle costs

  22. Selling IT Projects • Benefits of energy-efficient IT upgrades: • Technology improvement: Repair or replace • Energy savings: Lowers operating costs • Process efficiency: Improves work being completed • Extends life of equipment
