This is true. Even for an hour that you turn off all electricity, it has a huge effect and it allows you to save a lot of power. We also have lots of business establishments that leaves their lights as well as other electronic device turned on even at night. Meaning, its on 24 hours daily. I really hate it when I see these things. It pulls as closer to the edge. If were planning to save the environment, we should also include this.
Thanks
