I bought Nest early this early and so far it has been really smart (to compensate for my dumbness and laziness) and it did save me few bucks, but I haven't had the time to calculate the exact savings. Now Daniel Gross is installing two in his home and promises to report back soon:
So how should I expect this device to save me? It depends, said Fadell, on whether the user’s primary goal is saving energy or being very comfortable. “We’ve seen anywhere from 5 percent to 60 percent reductions,” he said. A typical home can reduce heating and cooling costs by between 20 and 30 percent, regardless of geographic location. Nest notes that its customers have collectively reduced their usage by 80 million kilowatt hours (compared with their pre-Nest energy profile), which is enough to take the entire American economy off the grid for 15 minutes.
Fadell notes that the Nest can only optimize temperature control. It can’t do much about other factors that affect efficiency, like poor insulation, leaky roofs, and open windows. The Nest’s value is that it can help people make the best, most rational and intelligent use of energy -- given the way they like to use energy and the physical condition of their homes house. Other features include True Radiant, which compensates for the longer time it takes for baseboard systems to adjust temperatures. In addition, Nests could help households play a role in demand-response programs – initiatives in which customers dial down usage of utilities during peak demand.
