Renewable electrical power sources offer a clean form of energy that is essential for the future. In areas with "good" sun exposure (insolation), like Santa Cruz, photovoltaic (PV) power can meet a significant portion of electrical energy demands. However, PV power is variable, and particularly as a result of weather phenomena. This thesis discusses options for smoothing the output of PV production of residential customers by use of a flywheel system. An economic proposition is also suggested in the context of electrical energy rate schedules that could provide cost incentives needed for this smoothing system and make it commercially viable. It is shown that flywheels used in this capacity are not the correct solution due to the constraints outlined within this thesis.
