Which behavior changes save the most money per year?
Unplugging devices like computers and chargers when they aren't in use pays off more than most other behavior changes. But line-drying clothing cuts greenhouse gas emissions the most.
Bars show unplugging unused appliances, turning off lights for an hour and line drying clothes all save $60 or $65 a year. Seeing the thermostat back 1 degree and turning off lights when you leave a room have much lower impact.
