How accurate is the use of data coming from weather maps?
Data on weather maps can be used for a first estimation to find a good location. However it does not take into account the specific wind speed at the location where the wind turbine will be located. An error of 10% in the measurement will have a deviation of 33% on the energy output. See (http://www.retscreen.net/ang/accuracy_of_project_cost_estimates_image.php). Q: Are vertical axis small wind turbines commercially available and usable? On the website www.allsmallwindturbines.com you can find information about horizontal and vertical wind turbines. Q: How do the power curves from vertical compare with the horizontal ones? On the website www.allsmallwindturbines.com the power curves are given for both types. In general the horizontal ones generate more energy compared to the vertical ones. Q: Are vertical turbines more appropriate for urban settings where there is more turbulence? In general vertical turbines are easier to install in urban areas. In general they are less noisy and less
