Saving Energy from Electricity

One more big surprise from my daughter when she mentioned about her new project. She is just five and a half years old now. But she already has quite brilliant idea about saving energy on electricity that we use in the house. She want to turn off the electricity that we don't need during the day and night and check what will be the difference on electricity bill later. If there will be cost saving, she want to know how long she should do that so the amount of the cost saving that she can collect and use for something more useful. What a great idea from a small girl like her. I love her more and more.... :D
