David Mull

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 adjust my thermostat down 2 degrees from usual when I use the heat, and up 2 degrees when I use air conditioning.

I will switch to washing my clothes in cold water, saving up to 1,600 lbs of C02 over the course of the next year.

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