Nest Labs is scaling fast.

The Silicon Valley company formed by Apple alums Tony Fadell and Matt Rogers, who helped build the consumer gadget giant’s iPod and iPhones, has acquired  Boston-based startup MyEnergy. The fledgling company helps homeowners understand their total energy use by presenting and analyzing all their electric, gas and water usage over certain time periods, and comparing it to other other homes in the neighborhood.

MyEnergy, which has been working with utility Minnesota Valley Electric Cooperative, will help Nest in its push to form partnerships with other utility companies to get the power-saving “Nest” thermostat into more U.S. households.
