The low energy of compensatory atmospheric movements near the surface and its pronounced increase with height dictate wind turbine systems of a size greater than any previously planned. Independent of the basic principle suggested, the most effective method of minimising the total expenditure is to use the highest possible specific speed. In cases where wind energy systems supply an appropriate amount of power to a grid, the analysis of the discrepancy between the momentary power available and the momentary demand has, assuming large-scale sepa ration of the wind turbines in available areas,...
