The manufacture of electrical goods consumes large amounts of energy and raw materials. They can also use a lot of energy when in use. Buying items which will last for a long time, ensuring they have a good environmental rating, looking after them properly, using them correctly, and not leaving them on standby can greatly reduce their environmental impact.
"Over six million electrical items are thrown away every year in the UK. It is estimated that over half of them are still working or could easily be repaired." (ITDG, 2003).
