Problems with wind turbines.
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.
