  1. Why Did President Bush Suddenly Start Talking about Standby Power? Alan Meier Lawrence Berkeley National Laboratory

  2. Standby Energy Use and Energy Savings Opportunities • Why did President Bush get interested in standby power? • How large is standby power? • Savings opportunities

  3. President Bush Saw This Display…. And wrote an Executive Order about standby …

  4. How Large Is Standby?

  5. A TOUR OF LEAKING APPLIANCES IN A TYPICAL US HOME All measurements given in watts

  6. (answering machine) (modem) 6.5 yrs

  7. (baby monitor)

  8. (CO sensor)

  9. (baby monitor)

  10. Total Leaking Electricity: 74 W

  11. 5 W Our New Neptune Draws 5 W

  12. 80.4W Tokyo 80W

  13. New Zealand 125 W

  14. Paris 70 W

  15. How Large Is Standby? • 5% of residential electricity (~50W) • 20 appliances/home • TVs and VCRs down, but number up • No estimates for commercial & industrial • Similar levels in other Europe, Japan • Urban Chinese homes: ~30W already! • ~1% of global CO2 emissions

  16. Reducing Standby Power 3 examples…

  17. Case Study: Internet Appliance

  18. Internet Appliance Savings

  19. Thermographs of Satellite/Internet/DVR Box “OFF” - 17 Watts ON - 21 Watts Power Supply Microprocessor

  20. The 2002 Calypso Washer. It’s bigger, better… and it uses 1/10 the standby power of Neptune.

  21. Reducing Standby Power • Components • Low power components (include displays) • Design • Don’t energize unneeded components • Power Supply • Reduce no-load loss • Improve efficiency at low loads • Move switch to high-voltage side
