The first pipe fitting couples to a pipe that supplies a fluid to a building. The turbine is in fluid communication with the first pipe fitting and rotates in response to a kinetic energy of the fluid supplied by the pipe flowing through the turbine, generates electricity in response to rotation of the turbine, and reduces a pressure of the fluid from a first pressure to a second pressure. The second pipe fitting couples the turbine to an input pipe of the building. The turbine further comprises a conversion circuit that conditions the generated electricity for consumption by the building and conveys the generated electricity to the building via one or more conductors.
