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 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 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 Data Centers are often housed in rooms not originally designed for IT equipment – Proper airflow management and improved cooling system design can help maintain optimum environments for this equipment 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
TBD – energy savings from going to LCD monitors CRT to LCD Monitor
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
Case Study: Efficient Cooling in Data Closet TBD
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
