Maximizing Your IT Budget through Energy Efficiency Heather Feigum Focus on Energy Advisor

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

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

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

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 What Does Focus on Energy Do?

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

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.

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.

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

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 IT System Challenges Source: U.S. Department of Energy: Energy Efficiency & Renewable Energy, March 2011

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 Data Centers = Information Factories Source: U.S. Department of Energy: Energy Efficiency & Renewable Energy, March 2011

Supply and Demand Energy Source: Emerson Network Power

IT Energy Supply Side Source: Emerson Network Power

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 Processor Efficiency Challenges

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 1 for 1 Initiative

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

Efficient Cooling in Data Closet Precision cooling v. Comfort cooling – Precision = % 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

IT Energy-Saving Opportunities 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 Electrical Power supply efficiency Standby/sleep power modes IT equipment fans Virtualization Multiuser computing ENERGY STAR IT Cooling

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

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 PC Network Case Study: UW-Oshkosh

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

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 Selling IT Projects
