I wonder what the total number of kW hours required to say, run the Apollo 11 mission. One factor would be in the fuel required, but I also mean in running the whole operation, manufacturering components, running control rooms, processing fuel, moving the rockets around, etc etc.
Which brings me to the fact that I just got a "Kill-A-Watt", after reading this blog post. I haven't tested everything yet (nor will I ever hah), but here are the results for the things I have:
The biggest thing that struck me is that my laptop, under normal use conditions, is using less power than desktop's monitor ALONE. Wow. I'll test more things soon, I get to reboot once again to remove the Kill-A-Watt from my desktop now.
- iPhone charger: 0.0W when no iPhone connected, 6W when charging (the classic "you should unplug wall warts when not in use" thing doesn't necessarily apply!)
- ReadyNAS NV (old sparc model, 3 WD and 1 Seagate 1TB disks): 50W
- Samsung 24" LCD: 45W, or 0W when in powersave mode
- Q6600 2.4ghz computer with single 7200rpm disk, GeForce 8600 GT, UAD-1 PCI-E card, idle: 115W, full load (with UAD-1 going): 185W.
- Sony VPC-Z12 laptop (dual core i7, SSD, 13" 1920x1080 screen, full brightness): 17W when idle in "speed" mode. 35W when idle and charging battery, 77W under full CPU load while charging battery.*
- Updated: Brother laser printer/scanner/fax: 6W idle
- Updated: Thinkpad X60 (1.83ghz C2D): idle 23W, 28W with full brightness setting
- Updated: PS3: 1W off, 100W idle, 120W in RE5.
- Updated: LG 36" LCD: 0.5W off, 45W on
- Updated: 24" C2D iMac: 125W idle, screen at full brightness, 146W full load
- Updated: ZT lunchbox amp: 18W cranked but not playing anything, 23W when playing loud
*I should also mention that this laptop is really wonderful, despite lacking home/end/pgup/pgdown keys, which makes me sad. It weighs only 3LBs, and is fast (i7 dual core, 4 threads, goes up to 3.2ghz or so in singlecore mode automatically), and even has an optical drive built in.
