Estimate of the surface area needed to generate 50MW/h of energy during various wind speeds. This graph assumes our turbine to be 45% efficient at converting the kinetic wind energy to electric energy. The area between the red and black line is the wind speed of category 3 hurricanes and the area between the black and green line are the wind speeds of a category 4 hurricane.
