1. An apparatus, comprising:
a first mover for generating a first mechanical energy, wherein the first mover comprises an internal combustion engine;
a well stimulation pump;
a second mover for generating a second mechanical energy, wherein the second mover is powered by electricity produced using natural gas, wherein at least a portion of the natural gas is obtained from a wellbore on-site; and
a drivetrain for outputting a combination of the first and second mechanical energies to the well stimulation pump,
wherein the combined first and second mechanical energies power the well stimulation pump to pump fluid to the wellbore.
