Even a small step can make a lot of difference. At least that is what actor Dia Mirza believes in.

The pretty lady who is a champion for eco-friendly living tells CS, `The small things make a lot of difference. For example, I make it a point to remove my charger from the socket and switch off the power after I finish charging my cell.

This is something most of us forget. In many homes, you will see the charger plugged in with the switch on. It wastes so much energy. Even with taps, people leave them on when they are not required.` Well Dia, you can surely give lessons on energy efficiency.
