Notes - Chapter 1 Summary

The following notes are taken from Wind Turbine Technology by Ahmad Hemami.

• Wind has been a source of energy since ancient times
• Persian Windmill Vertical Axis, 1000 years old
• Dutch Windmill Horizontal Axis, built in 12th century
• Early wind turbines much smaller than modern turbines
• 4 MW
• Earth has limited resources that must be balanced
• Sufficient wind energy in the world to power everything but has difficult to use energy load
• wind turbines have small production capability
• requires smart grid to allow electric network to compensate for any additional loads or additional production
• Electric Energy measured in KW hours
• CO₂ generated .712 kg per kw-hr
• Wind development requires good wind profiling
• wind speed increases with height
