You turn on the button when you need to use the equipment and turned off when you finished using it. Many people do not know that, although home appliances are turned off they are still consuming electricity. Plastics are the best material to insulate, but on moveable objects we might want to use weather strippers which seal a moveable object from its non-moveable object like doors, windows and garage doors. Then comes the blinds and drapes. We should choose those drapes which cover the windows entirely and open them when the weather is sunny to naturally let the heat insulate our home.
