Extensions are used mainy in two scenarios 

1. When your page has a Standard Controler : This is the most when you use extension class to develop custom logic as with standard controller you can not use Controller

2. When you have  controller class : In such scenario mostly you do not need as you can write custom code in your controller class. But sometimes due to design perspective and to keep modularity etc we do use extensions classes.
