An energy generation system, has a roof that is configured to rest upon a structure. A frame is joined to the roof with a mounting bracket. A turbine arranged in the frame with a first turbine shaft and a second turbine shaft. A first alternator is joined to the first turbine shaft with a first drive gear. A second alternator is joined to the second turbine shaft with a second drive gear. A switching system is joined to the first alternator and the second alternator. The switching system is programmed with a loop of instructions to determine a turbine rotational speed. Then, engage the first alternator. After that, monitor the turbine rotational speed. Following that, engage the second alternator.
