It is easy to be green and technically advanced, but even easier to waste our valuable resources.

1. Do not buy new equipment until either the old is not up to your needs or unable to support you through a new venture

2. Turn off at the mains at all times when the equipment is not in use.  Computers and especially printers use far more than a TV on standby.

3. If you don't need to print it don't.  It is far better to buy a few memory sticks and keep copies of your documents in secure reliable tiny electronic storage than paper in files; it takes far less energy to store data than to print it.

4. Whilst it is sometimes convenient to have several applications open at the same time it is also more demanding on the PC so it will use more power.  If you can work for five minutes without the application on screen then close it and re-open it when you need it.

5. Wireless frenzy!!  Do you really need a wireless thingy - mouse/keyboard/network?  Just bear in mind the cable you used to use needed no power to make it work compared to the power and batteries used to go wireless.  Don't be a victim of the marketing hype.  If you do need batteries then always fit rechargeable ones - they last years and are very efficient to charge.  ...and do you really need a new phone every year?
