The Modern Wind Energy Industry
. Many countries began exploring alternative sources of energy during the oil shortages of the 1970s. As improvements in wind energy technology have evolved, the modern wind energy industry has emerged. Increasingly, modern wind turbines produce electric power as efficiently as other power generation technologies. One of the major obstacles for developing wind energy is finding suitable terrain and wind conditions. Placement of Wind Turbines Wind Turbines Wind speeds in the Lake Benton, Minnesota, area average about 26 km/h (16 mph), making it the windiest region in the state. These turbines are equipped with special features to operate in this cold climate. Location is critical for maximizing the electricity wind turbines can produce. The amount of kinetic energy available in the wind is a cubic function of wind speed—that is, for every doubling of wind speed, there is a corresponding eight-fold increase in available energy. This exponential relationship between wind speed and wind en
