[Should we build a wind farm?] Wind Power has been the most popular alternative energy choice in recent years. One of the key determinants for choosing a location for a wind farm is whether the site has enough wind. To produce enough energy using current technology, the site should have an annual average wind speed exceeding 9.25 miles per hour, according to the Wind Energy Association. One candidate site in southern California was monitored for a year, with wind speeds...
