More Power Usage Measurements
About 18 months ago I did some measurements of the power usage of some of the gear in my loungeroom using a kill-a-watt meter. It was interesting to see how high the standby power usage was of some devices, in the context of standby power apparently representing around 10% of residential power consumption.
After recently attending a screening of a well thought out climate-change catastrophe film, The Age of Stupid, I've been inspired to go through the same process with some of the gear in my computer room - and it seems I can easily shave another 10-20w off my home's standby energy use just by turning stuff off at the wall when I'm not using it. The most convenient way I know of to do this is using a power board that has an on/off switch for the whole board.
Here's some of the numbers for the curious:
| Device | Standby | Running |
|---|---|---|
| Denon PMA-880R stereo amplifier | n/a | 16w silent, 50w in use |
| Pioneer VSA-701S AV amplifier | 2w | 30w silent |
| 2nd PC, 3ghz P4, Nvidia 6600 | 8w | 115-150w |
| Logitech X-210 PC speakers | 5w | 7-9w |
| LG Flatron 19" monitor | 1w | 19w |
| Asus eee 1000HA netbook | 27w (off, charging) | 37-40w (on, charging), 15-18w (on, no battery), 14-15w (on, no battery, screen off) |
| Dell 2408 Ultrasharp 24" monitor | 1-2w | 44-47w |
