You chose "Home Heating"

By turning down your thermostat just one degree in the winter, and one degree up during the summer, you can conserve on average 1.2 pounds of CO2 per day!

Just buy the Nest. Tony Fadell somehow managed to make a thermostat the coolest thing in your house.

We were only disappointed when we asked it to "beam me up," and nothing happened. Maybe that feature is still on the drawing board..
