I will keep lights, electronics, and appliances turned off when not using them.

I will naturally heat and cool my house, office, or dorm room by opening or closing my windows, curtains, and blinds, and by using fans.

I will power down my computer and monitor when not using it for more than 2 hours, saving up to (1.1) lbs of CO2 each day that I do this.
