EnergyUsage
PLEASE NOTE: The table below isn't getting formatted properly. I'm working on figuring out why.
I recently received a Kill A Watt as a gift and have been testing various electronics around the house and at work to see how much energy they use. Here is the data so far, along with a calculation of the cost of running each device 24x7 for 30 days:
| device | KWH /Hour | KHW /30 days | low cost* | summer high cost* (May - Oct) | winter high cost* (Nov - Apr) |
| Hitachi Accuvue monitor | 0.1183 | 85.141 | $4.73 | $8.36 | $6.83 |
| computer (in use) | 0.1000 | 72.033 | $4.00 | $7.08 | $5.78 |
| computer (idle) | 0.0978 | 70.400 | $3.91 | $6.92 | $5.65 |
| Dell 17" LCD monitor | 0.0318 | 22.909 | $1.27 | $2.25 | $1.84 |
| DVD player (on; not playing) | 0.0100 | 7.179 | $0.40 | $0.71 | $0.58 |
| ionizer/nightlight | 0.0027 | 1.943 | $0.11 | $0.19 | $0.16 |
| Omni Cube KVM | 0.0009 | 0.635 | $0.04 | $0.06 | $0.05 |
* Cost calculations are based on the following residential rates from Austin Energy:
| description | cost |
| fuel charge | 0.02004 |
| low (first 500 kWh) | 0.0355 |
| summer high (for all kWh over 500 kWh) | 0.0782 |
| winter high (for all kWh over 500 kWh) | 0.0602 |

Note
- I've converted the Blueberry Boat theme used on my blog to work with PmWiki. Wide pages will need to be reformatted, but the "print" links at the bottom of the pages should make them readable in the meantime. Please contact me, if you have any feedback on the new theme.
