We're almost there. What we're trying to calculate is the efficiency of the turbine, which is the ratio of power extracted from what is theoretically possible (which is what we stared the article off with). We'll call this efficiency η Differentiating this with respect to Z and setting ...
a big wind area, thereby making full use of wind power, with high conversion rate of wind energy; one side of the blade is connected with the whole of the spindle, and the torque generated is small, resulting in small wind energy loss and high efficiency of the generator in unit space....

More countries are expected to grow as the cost of wind power reduces. The cost reduction however depends mainly on the technology improvements, related to the efficiency ofwind turbines, the installation, and maintenance. For the past 30years, theonshore windpower costs have dropped significantly...
