An articulated erection structure is disclosed for use in mobilizing a wind energy extraction device. The wind turbine has blades capable of being disposed in side-by-side, parallel alignment for transportation. The erection structure has a mast that can be configured in a horizontal orientation for transportation with the turbine generator lowered, and reconfigured for power-generating operations in a vertical orientation with the turbine raised. The turbine generator may be mounted with an erection structure to a variety of transportation platforms, such as on a self-propelled vehicle, towed trailer, or transportation pallet. A hybrid system may integrate photovoltaic cells in addition to a wind energy extraction device.
