10 tech ways to go green and save money

Simple ways to save the world


Reuse and recycle


PCs: Under the WEEE directive, UK PC manufacturers have to take and recycle computers at the end of their lives, but perhaps the best thing you can do with an old computer is to donate it to a charity that will reuse it. See Green computing & PC recycling made easy for more.

When buying new, go green


Earth-friendly PC: Hewlett-Packard offers a full line of Energy Star-compliant products. The The HP Compaq 2510p laptop (reviewed here) comes with an 100GB SATA hard drive, 1GB of DDR2 memory, an Intel Ultra Low Voltage U7600 processor, and the Windows Vista Business operating system. Under optimum conditions, according to HP (and our tests), it consumes much less energy than a standard laptop.

Green storage: Western Digital's Caviar GP WD10EACS is a 1TB hard drive that consumes less power and operates at lower temperatures than comparable-size drives. It scored fairly well on our tests against a similar non-green hard drive.


A different kind of pod: Your iPod is great, but how energy efficient is the constant recharging? Maybe you should try a Wind Up Eco Media Player (£150) instead. This device has an FM stereo radio, plays video and music, and comes with a built-in microphone, LED light, and SD Card reader.

To charge its 20-hour battery, you turn a crank at the back - 1 minute of winding yields 40 minutes of audio playback. (Or you can plug it into a USB port and let the electric company do the cranking.)
