Wind (or windmill) is a way to free energy by reducing the fees paid for fuel, heating, electricity, etc. Electricity from the windmill is best used for heating water in a boiler, space heating, etc.
If you have central heating is advisable to put additional electric heaters in the water, to which it is supplied power from the generator. In such cases, no agreements are needed to stabilize voltage generator, for example, when the winter wind blows at the same time heat boiler, and when the wind blows the heater, of course, not heat, but the demand for heat is also smaller.
Additional incentive to build wind power plant is able to benefit from tax relief, ie, deduct the cost of the construction of the agricultural tax.
