After harvesting energy from the wind for centuries, for a long period in history which started with the industrial revolution, wind power development has lagged behind due to the advent of other types of technologies based on fossil fuels and nuclear fission. It was not until the 20th century that technological developments in other fields revolutionized wind power conversion and ultimately led to modern wind turbine systems. This re-emergence of wind as a significant energy source is now encouraged by the need to meet increasing worldwide electricity demand and reduce the environmental impact caused by the conventional electricity generation technologies. Considerable progress in wind-power technology during the last decades has [...]
