A wind energy collection and conversion system includes a plurality of turbine assemblies. The turbine assemblies rotate on a common axis transverse of a base. A plurality of shutter assemblies are disposed in a circular orientation around each of said turbine assembly and are independently operable for causing wind current to be directed thereby for rotating said turbine assemblies. Five wall elements extend outwardly tangential to the periphery defined by the shutter assemblies and intercept the wind current and direct the wind currents toward the shutter assemblies. A roof covers the power plant and thereby increases the overall efficiency.
