When you get rid of an old computer, you need to dispose of it properly otherwise it can cause environmental damage. Instead of throwing away the computer, it can be reused, refurbished or recycled (Saha, 2014, p. 48). This means giving or selling old computers to those in need, repairing old computers so they can be used, or even using old computer parts (Saha, 2014, p. 48). While green computing has many environmental benefits, there are also some risk factors involved. For example, green computing is a very expensive concept. Global warming in general most often contributes to the fact that people have found cheaper ways to do things despite its environmental effects. A big problem would be convincing customers to spend the money to save in the long term
