Problems with wind turbines.
The first wind turbine in the US, built by Charles F. Brush, had a 17 m diameter annular sail with 144 thin blades made of cedar wood. The first wind turbine in Europe, built by Paul La Cour in Denmark, had four traditional slatted wooden sails with a rotor diameter of 22.8 m.
According to Cedric Philibert, a renewable-energy expert at the International Energy Agency (IEA), conventional wind turbines in European waters could generate 2600–6000 TWhr per year, or 80–180% of current EU demand – but only at a cost of €55–70/MWhr. The current price in France, Philibert notes, is €44/MWhr.Oct 13, 2020 · As wind turbines increase in size and capacity, gearbox failures are expected to continue being a problem for wind power plant operators unless bearing axial cracking can be reproduced in the laboratory, computationally modeled, and compared with actual power plant results.
