Harnessing the Wind
The small wind turbine supplies the required electricity to keep the SHARE farm running.  The wind generated electricity powers the following systems: EMS, solar thermal intake fans, circulation fans, motorized roll up curtains, and irrigation pumps.

Choosing to power the farm with clean wind energy is not simply a environmentally positive decision.  It makes sound economic sense as well.  Under an agreement called net metering, the excess electricity generated by the wind turbine can be sold back to the local utility at retail rates, earning you a highly reliable source of income.  The turbine owner also qualifies for a host of utility, state, and federal incentives that lower the financial payback on the wind system.

Wind is a form of solar energy. Winds are caused by the uneven heating of the atmosphere by the sun, the irregularities of the earth's surface, and rotation of the earth. Wind flow patterns are modified by the earth's terrain, bodies of water, and vegetation. Humans use this wind flow, or motion energy, for many purposes: sailing, flying a kite, and even generating electricity.
 
The terms wind energy or wind power describe the process by which the wind is used to generate mechanical power or electricity. Wind turbines convert the kinetic energy in the wind into mechanical power. This mechanical power can be used for specific tasks (such as grinding grain or pumping water) or a generator can convert this mechanical power into electricity.

So how do wind turbines make electricity? Simply stated, a wind turbine works the opposite of a fan. Instead of using electricity to make wind, like a fan, wind turbines use wind to make electricity. The wind turns the blades, which spin a shaft, which connects to a generator and makes electricity.

Local Wind Resources

Both Minnesota and Wisconsin, likely states for the initial SHARE farms, have adequate to above average wind resources.  Minnesota has a class 5 wind belt in the southwest corner of the state where numerous utility scale wind farms are located.  However, the southeast corner of the state, a region with a high number of organic produce farmers, has more than adequate wind resources for a SHARE operation.  The southwest part of Wisconsin has upper class 3 and lower class 4 on ridge tops in the “Driftless” region.  Other regions with above average wind resources in the state are west central Wisconsin along the Minnesota border, the southern region bordering Illinois, and the Door Peninsula extending into Lake Michigan.
