2. contents  Introduction  Devices which use standby power  Tips to reduce vampire power  Smart Power Strip  Conclusion

3. INTRODUCTION  Many household appliances are never fully plugged off, but spend most of the time in a standby mode.  A 2000 study said standby power accounted for around 10% of household power-consumption.  Many appliances continue to draw a small amount of power when they are switched off.

4. Whole New Language  Miscellaneous Electricity  Leaking electricity  Phantom load  Power surge & suppression  Transient voltage  Low power  Standby

5. Total Household Electric Use = Baseload + Seasonal Baseload: Electricity used to power things used year round Seasonal use: Electricity used to provide heating, cooling, often dehumidification Source: 2005 Building Energy Data Book

6. Why Address Baseload? Electricity Use is Rising Mark Fortney, 2007, PHRC, PA Home Energy Forum

7. Power Settings & Mode ON  Active power  Low power mode  Indeterminate power  Sleep/hibernat e REALLY OFF  No power  Unplugged  Power switched off with strip or other control device “OFF”  Standby power  Phantom load  Vampire power  Idle power Anything with a remote, display, touchpad, or light is using power even when turned “off”

10. STAND BY POWER MEASUREMENT  Metered 118 Watts when turned “off” Cost Calculation 118 W x 8760 hrs/yr x.001W/kW = 1033 kWh @ $0.14/kWh = $145/ yr

11. PC & Peripheral Use  CPU running VISTA Sleep: 4W standby Shut Down: 2W standby  Printer: 3W standby  Monitor: 1W standby  UPS/Battery back up: 8W standby  Active Power for all the above: 140W

12. Low W Standby Products Needed For New Construction! Doorbells: 18W Thermostat transformer: 4W Security system: 15W Smoke detectors/GFI: 0.4 -1.0W ea. Garage door openers: 5W Danny Parker, 2008 FSEC

13. Battery Charging Strategies  Chargers can draw 5 to 20 times more power than they can store so... Unplug chargers once battery is charged Use timer to control charge cycle  Choose equipment based on charging performance  Buy efficient chargers  Use rechargeable batteries  Use power strips to simplify disconnecting chargers

15. Simple Payback for Power Strips  Using a standard power strip saved 0.5 kWh/day for house hold Devices– about 183 kWh/yr  Using an Occupancy Sensor strip in home office standby saved about 0.3 kWh/day – about 109 kWh/yr Is this significant?  These two actions saved 292 kWh/yr  At Rs.0.22/kWh this equals about Rs.2000/yr  For a seven month payback!

16. Strategies to Control Home Electronic Energy Use  Unplug stuff you don’t use  Manage control settings for maximum efficiency  Turn equipment off when not actively using  Minimize standby use with power strips, unplugging, etc.  Purchase less stuff  Buy the most efficient products possible
