A condensed history of wind energy Growth of wind energy conversion systems Ancient past Introduction to wind power plants Recent past Acknowledgments References A condensed history of wind energy Not-so-ancient past: early 20th Century from the DOE [2] Approximately 6 million windmills once dotted the Western US landscape circa 1890 Around the same time, Denmark started to introduce large windmills called ‘wind turbines’ Danes are the first to generate electricity from wind turbines [3] A 1 . 25MW turbine in VT known as Grandpa‘s knob supplied electricity to a local utility in the 1940s. See figure from [3] Wind industry productions slacked in the 1950s Suryanarayanan ECE 566 Lecture/Week 1: Part B
