In 1982 wind energy development in the San Gorgonio Pass area was formally studied, and the results published in the "San Gorgonio Wind Resource Study EIR (1982)", a joint environmental document prepared for the U.S. Bureau of Land Management and Riverside County. The document assessed three scenarios for wind energy development in the area and included criteria for the development of wind energy on both a countywide basis and specifically for the San Gorgonio Pass area. Since 1982, and the approval of wind energy development in the San Gorgonio Pass, numerous wind turbines have become part of the landscape. The narrow turbines range from to in height.
