How to save energy on your computer

Even when you're using your PC, you can do your bit for the environment (and your wallet).

Turn your computer off when you're not using it. Never keep it on overnight. At the very least, turn the monitor off.
If you have an old CRT monitor, get a TFT. They cost more, but look better and use less energy.
Don't bother with bright fancy screensavers. Use a plain black screensaver to save as much energy as possible.
Try to reduce your time on the computer. Do more in less time, and try multitasking.
