If the conditions are right, you may be able to produce adequate energy for your home if you build wind power turbines and produce your own electricity.  It is a great concept that is used in many countries to supply electrical needs.

Wind supplied energy has become competitive with other forms of electrical production.  In commercial applications, wind turbines have proved quite successful, but in small domestic cases, the results were different.  Even though the wind is free, small turbines do not produce enough electricity for what they cost to install.  You should be sure to size yours for what your needs will be.
