Is Tower Height Crucial for Optimal Wind Power Generation?

Click For Summary
SUMMARY

The height of a wind generator's tower is critical for optimal wind power generation due to the increase in wind speed with elevation, which allows for larger rotor sizes and improved energy capture. A 50-meter tower typically requires a wind power class of at least 3 and a power level of around 200-300 kW to be considered economically viable, particularly in the context of 2005. The discussion highlights the importance of understanding the velocity profile of wind and its impact on turbine efficiency and economic feasibility.

PREREQUISITES

Hi, Why is height of a wind generators tower so important? Given a 50-meter tower, at what wind 'power class' and at what 'power level' will wind power be considered economical (circa 2005)?

Wind speed (usually) increases with height, and more height allows bigger rotors as well.
 
Google "Wind Power"

If you look at the velocity profile of a fluid moving across a flat horizontal plate you will see why elevation above the surface is important.
 
Thank you both very much-

Any ideas on if given a 50-meter tower, at what wind power 'class' and at what 'power level' will wind power be considered economical (in or about the yr 2005)? Best wishes,
 
Was any turbine "economical" in 2005? Even today many need subsidies.
