Conservation

I actually have some artwork to show today, but my Photoshop CS3 trial has just expired, and I don't quite have time to deal with buying the upgrade just right now. So I'm skipping the photo. But it's the Lake Oswego Chronicles piece, back from the framers. It's huge! (But it looks good.)

But on other fronts: about a month ago—hey, it was exactly a month ago, because I was complaining about Photoshop breaking with moving to leopard, which was what prompted me getting the Photoshop CS3 trial to start out with—in this post, I mentioned that I was trying to spend less time on the computer, turning off the monitors and sleeping the computers when they're not in use, and also switching the most commonly used lights to fluorescents. Well, I just checked our May electricity usage against May a year ago, and it's down 20%! It's also down against April this year, although not by as much because we started our efforts sometime in the 2nd half of April already. I'm amazed that it's made that much of a difference. In actual numbers, it's 19.7 kWh per day, down from 24.7 kWh per day. Not sure if those numbers are good in absolute terms, but down 20% is pretty significant anyways.

unplug everything not in use, plugged in appliances is using power even not in active use. And since it's summer, maybe you should consider not to have your water heater on all day long. I bet that would make a lot of differences.

gl -- it's nice to have the feedback. I am really impressed that it made that much of a difference though.

shumei -- isn't that only true for appliances that's in a 'listening' mode, like listening for a remote control type of thing? We don't have anything with remote controls. Not sure about the water heater, I'll need to check into that. But it's not electric, so it won't make any difference on the electricity usage. It might affect gas usage, but I'm not sure that turning it off completely will be a saving, since it will have to come back up to temperature again when you turn it back on.

Anything that in a standby mode uses electricity, so that means anything that still has a little green light on when you turn it off. I don't know about the remote control part. But Japanese did a lot of shows on how to save electricity and water bill, and a lot of them just shut down the main switch. I shut the ACs from the main switch because they have independent switches. We use gas for hot water, but it's not hot water stored, but heated when it come through the pipe. I did notice that even I use only cold water, the machine will sort of buzz as if in use. So I turned that off during the day.

We don't have anything that has a standby mode. So can't cut there. I thought about putting in an in-line heater years ago, did some research, but didn't find anything suitable. Things might be different now.
