Is Tower Height Crucial for Optimal Wind Power Generation?

Click For Summary

Discussion Overview

The discussion centers on the significance of tower height in wind power generation, particularly regarding its impact on wind speed, rotor size, and economic viability. Participants explore the relationship between tower height and wind power classes and levels, with a focus on the context of the year 2005.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • Some participants note that wind speed typically increases with height, suggesting that taller towers can harness more energy.
  • Others mention that greater height allows for larger rotor sizes, which may enhance energy capture.
  • A participant references the velocity profile of fluids to explain the importance of elevation in wind energy generation.
  • There is a query about the specific wind power class and power level at which a 50-meter tower would be considered economical around 2005.
  • One participant questions the economic viability of turbines in 2005, indicating that many still required subsidies even in the present day.

Areas of Agreement / Disagreement

Participants express varying views on the economic aspects of wind power generation in 2005, with some uncertainty about the specific conditions under which a 50-meter tower would be deemed economical. The discussion does not reach a consensus on these points.

Contextual Notes

The discussion lacks specific definitions of "wind power class" and "power level," and there are unresolved assumptions regarding the economic context of wind power in 2005.

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.
