On a hot summer night, you invite your friends home. First cool your house, bring iced drinks to your friends (Make sure your fridge is running efficiently). Then play games and watch movies with them. After your friends leave, tidy up the room and go to bed.
Wash yourself completely, including your hair. And then do laundry. Wash and dry your clothes. After all these are done, go out and meet your friends.
On a Sunday morning, help your mom prepare breakfast for your family, including heating the milk with the microwave, making toast and fried eggs. Then wash the dishes and leave the kitchen.
Some things have to either stay on or run automatically in your house, like your fridge, some could remain off while not in use. Other things run automatically to control temperature. Make your house run as energy efficiently as possible before you go to bed.
