Article on heating water at off-times to save power

There is an article on the EERE site that displays information on how to save energy by using these heaters at off-peak timings / by using a timer (link). The article also contains more links on the following topics:
Install Heat Traps on a Water Heater Tank for Energy Savings
Lower Water Heating Temperature for Energy Savings
Reduce Hot Water Use for Energy Savings
Insulate Hot Water Pipes for Energy Savings
Drain-Water Heat Recovery
Insulate Your Water Heater Tank for Energy Savings
Select a New Water Heater.

If you have an electric water heater, you can save an additional 5%–12% of energy by installing a timer that turns it off at night when you don't use hot water and/or during your utility's peak demand times.
Contact your utility to see if it offers a demand management program. Some utilities offer "time of use" electricity rates that vary according to the demand on their system.

When you are old and rich

An elderly lady was stopped to pull into a parking space when a young man in his new red Mercedes went around her and parked in the space she was waiting for.
The little old lady was so upset that she went up to the man and said, "I was going to park there!" The man was a real smart Aleck and he said, "That's what you can do
when you're young and quick."
Well, this really upset the lady even more, so she got in her car and backed it up and then she stomped on the gas and plowed right into his Mercedes.
The young man ran back to his car and asked, "What did you do that for?"
The little old lady smiled and told him, "That's what you can do when you're old and rich!"

Reducing The Power Consumption Of Overclocked PCs

This is a great article about reducing the power consumption of Overclocked PC's (link). Some excerpts:

Now, that must sound pretty inane. Overclocking a PC seems to be as far apart from power saving as it can get. After all, overclockers employ all kinds of power-guzzling methods to improve their CPU's overclockability, from increasing the CPU core voltage to employing more powerful cooling systems. Even the act of increasing the clock speed increases power consumption.

Having overclocked all my PCs for the past 10 years, I am one of these overclockers. I have overclocked everything from a 300 MHz AMD K6-2 processor up to my current gem, an Intel Core 2 Duo E6850. I've even gone to the extent of water cooling almost every processor I've owned since the year 2000. So, the decision to reduce power consumption would seem insane, even to me.

However, there are a few good reasons why I would want to do this. Even though I love overclocking my PCs and making them run to the best of their ability, the increased power consumption has resulted in :

* A very hot room, especially in the afternoon!
* High electricity bill.
