Wind

Wind power could be considered "indirect solar power", because this resource is created from atmospheric pressure differentials generated by the sun. Wind resources are plentiful in many parts of the United States. Wind Energy systems take the kinetic energy of the wind and convert it to mechanical energy to make electricity. There are a number of "wind mill" designs taking advantage of this clean resource. While it is possible to use one small wind mill to power a house or farm, the usual application is to group numbers of the machines together in 'wind farms". The collective power from the individual turbines is transferred to an on-site substation where the voltage is increased to meet the utility's grid requirements. California leads the world in the application of wind power for electrical generation, with a majority of the facilities in the Altamont Pass area in Northern California and the Tehachapi and San Gorgonio Passes in southern California.
