INTERNATIONAL ENERGY AGENCY AGENCE INTERNATIONALE DE L’ENERGIE Reducing Standby Power to 1 Watt (and less) Alan Meier International Energy Agency Presented at KEMCO 29 July 2004 Updated 30 July 2004

INTERNATIONAL ENERGY AGENCY AGENCE INTERNATIONALE DE L’ENERGIE Seminar Plan What is standby power? How large is standby? The IEA 1 Watt Plan Policies to cut standby The future

INTERNATIONAL ENERGY AGENCY AGENCE INTERNATIONALE DE L’ENERGIE What is Standby Power? Power consumed by an appliance when switched “off” or while not performing its primary purpose

INTERNATIONAL ENERGY AGENCY AGENCE INTERNATIONALE DE L’ENERGIE How Large is Standby? Device Home Country World

Standby Power of each product is tiny--just a few watts-- but most homes have more than 15 products with standby 1 Watt = 9 kWh/year

INTERNATIONAL ENERGY AGENCY AGENCE INTERNATIONALE DE L’ENERGIE Standby: up to 25% of Electricity Use in Some Homes

Measured Standby in 10 California Homes USA refrigerator standard

INTERNATIONAL ENERGY AGENCY AGENCE INTERNATIONALE DE L’ENERGIE How Large is Standby? – 10% of residential electricity in most countries Unknown % in commercial buildings ~1% of global CO 2 emissions

INTERNATIONAL ENERGY AGENCY AGENCE INTERNATIONALE DE L’ENERGIE The IEA 1-Watt Plan (1998) Reduce standby in all products to < 1 Watt by 2010  50% by 2005 Each country will select its own policies  Labels  Standards  Government procurement Countries will collaborate and agree on:  Definition & test procedure  schedule

INTERNATIONAL ENERGY AGENCY AGENCE INTERNATIONALE DE L’ENERGIE Progress Report Countries with a 1-Watt Plan  Australia  United States  Korea  Japan (sort of) Countries with special policy for standby  China  Europe (sort of) Good summary at

INTERNATIONAL ENERGY AGENCY AGENCE INTERNATIONALE DE L’ENERGIE Special Aspects of Standby External power supply agreement  China, Energy Star, Australia, California  Standby < 0.5W  On-mode : > 0.09 * Ln (P no ) IEA agreement on simple set-top boxes (decoders)  8 W active  1 W standby  Remote control shifts from active  standby

INTERNATIONAL ENERGY AGENCY AGENCE INTERNATIONALE DE L’ENERGIE IEC Definition and Test Procedure will be formally adopted in late Definition: “The lowest power consumption mode which cannot be switched off by the user ….

INTERNATIONAL ENERGY AGENCY AGENCE INTERNATIONALE DE L’ENERGIE Korea Discussion Topics What appliances should be covered?  Meier: “all products plugged into standard outlets” Which policy is better: Mandatory or voluntary?  Meier: “mandatory, because all manufacturers will have the same costs; this is fairer to manufacturers” Should Korea adopt IEC Definition and Test procedure?  Meier: “yes, copy Australia approach” In September 2003 Standards Australia published an interim test method for the measurement of standby power AS/NZS (int.) and this is now available for purchase. This standard will be referenced by test methods or regulatory standards where standby requirements are specified. This is based on the IEC CDV of the standard of the same number.Standards Australia

INTERNATIONAL ENERGY AGENCY AGENCE INTERNATIONALE DE L’ENERGIE U S A Executive Order Energy Star California and other states

INTERNATIONAL ENERGY AGENCY AGENCE INTERNATIONALE DE L’ENERGIE 3 Years Ago President Bush Saw This Display

July 2001 Executive Order on Standby Power “…Each agency… shall purchase products that use no more than one watt in their standby power consuming mode… where cost effective…” 2 months later

INTERNATIONAL ENERGY AGENCY AGENCE INTERNATIONALE DE L’ENERGIE Energy Star & Standby Focus of today’s specifications:  Office equipment: sleep mode  Consumer electronics: standby Generally weaker than Executive Order Future  All modes for office equipment & consumer electronics & external power supplies  Set-top boxes: 1 W on standby

INTERNATIONAL ENERGY AGENCY AGENCE INTERNATIONALE DE L’ENERGIE California California Energy Commission has authority to make standards  Other states often copy California Proposed standards for  external power supplies (same as Energy Star)  simple decoder set-top boxes (8W/1W)

INTERNATIONAL ENERGY AGENCY AGENCE INTERNATIONALE DE L’ENERGIE Japan Meeting Kyoto obligations is major reason for Japanese activity  METI gave grants to industry to study problem  Demonstration VCRs, microwave ovens, ACs 2001: The 3 major appliance manufacturers associations promise to reach 1-Watt on all major appliances by 2004 Standby is not included in TopRunner standards

INTERNATIONAL ENERGY AGENCY AGENCE INTERNATIONALE DE L’ENERGIE Australia First country to adopt a policy on standby Coordinated through Australian Greenhouse Office Actions so far  Set goal of 1-Watt on all appliances  Leads IEC tech. committee on test procedure  Supported external power supply spec.

INTERNATIONAL ENERGY AGENCY AGENCE INTERNATIONALE DE L’ENERGIE China Recent study found high standby  High growth rates expected Voluntary standby levels for TVs China is collaborating on specifications for  external power supplies  Set-top boxes

INTERNATIONAL ENERGY AGENCY AGENCE INTERNATIONALE DE L’ENERGIE Europe Voluntary “Codes of Conduct”  Power supplies ( W depending on rating)  Set top boxes  TVs, VCRs?? Mandatory standards soon?  “Ecodesign Directive” Early target will be standby

INTERNATIONAL ENERGY AGENCY AGENCE INTERNATIONALE DE L’ENERGIE The Future of Standby We still don’t know if standby energy use is growing or shrinking  Some appliances are more efficient but now there are more appliances with standby!  A “networked home” will be a high standby home if no measures are taken  We need to monitor homes & offices

INTERNATIONAL ENERGY AGENCY AGENCE INTERNATIONALE DE L’ENERGIE The Future of Standby (2) We need to change test procedures to include standby for large appliances (dishwashers, AC, etc. ) Standby --> LOw POwer MOde energy use  Need to consider energy implications of all low power modes (lopomos)

INTERNATIONAL ENERGY AGENCY AGENCE INTERNATIONALE DE L’ENERGIE End Thank You!
