Am i the only one confused by this part ?

> I looked at the energy usage data from our Nest thermostat and discovered that those levels corresponded almost exactly with the times that our gas furnace was on.

Another way of seeing this could be that nest is turning on the heat between 2am and 7am, and it looks like the author was not aware of this. so yeah the gas stove is bad but not as much as the heating system, and the fact that a "smart thermostat" turns it on at night when it should be less useful.
