How big are wind farm projects?
Wind farms can range in size from a few megawatts to hundreds of megawatts in capacity, from one turbine to as large as 400 or more turbines. Wind Capital Group typically focuses on utility scale projects that are 50 MW or greater. Generally, this translates to 20 or more turbines, depending on the turbines used.

How big is a wind turbine?
Utility-scale wind turbines for land-based wind farms come in various sizes, with rotor diameters ranging from about 50 meters (164 feet) to about 120 meters (394 feet), and with towers of roughly the same size. A wind turbine that Wind Capital Group might use at this time has a total height from the tower base to the tip of the blade of approximately 400 feet.

WIND ENERGY BASICS
What is wind energy?
Wind energy is a converted form of solar energy. The sun’s radiation heats different parts of the earth at different rates - most notably during the day and night, but also when different surfaces (for example, water and land) absorb or reflect heat at different rates. This, in turn, causes portions of the atmosphere to warm differently. Hot air rises, reducing the atmospheric pressure at the earth’s surface, and cooler air is drawn in to replace it. The result is wind. Air has mass, and when it is in motion, it contains the energy of that motion (“kinetic energy”). Some portion of that energy can be converted into other forms of mechanical force or electricity that we can use to perform work.
