Acceleration of wind energy: mirage or reality? 1 - News: Despite strong ambitions, the market remains feverish; The industrialisation of the marine sector, the step not to be missed; PPA, a booming market; Denmark, the future face of the French offshore? Biodiversity (finally) under scrutiny; 2 - Technique: Repowering or how to give a new life to wind farms; Sensors and radars: allied to produce data; Maintenance, basis of the safety of machines and men; Climate change requires the anticipation of its impact on production; 3 - Law: Jurisprudence: The noticeable decisions of 2023; Wind energy and protected species: let us change the terms of the debate to get out of it; The lawmaker and wind turbines: 'I love you, neither do I'

A first set of articles discusses news related to the development of wind energy: the feverish situation of the market (measures must be taken to comfort investors and to strengthen the value chain), the necessary industrialisation of the marine sector of wind energy (actors must be collectively ready to face the acceleration of the installation of offshore wind farms), Denmark as a possible model for the development of offshore wind energy in France (the example of the Esjberg harbour, the Danish experience in the field of environmental and local constraints, the development of energy islands), an overview of the development of the PPA (Power Purchase Agreement) market, and the launching of research programmes aimed at a better knowledge of the impact of offshore wind farms on biodiversity. The second set addresses technical aspects: the development of repowering to give a new life to old wind farms with higher performance, the use of sensors and radars to produce data (installation by France of its first offshore mast), the crucial role of maintenance to ensure the safety of machines and of men, the necessity to anticipate the impact of climate change on energy production (influence of variations of wind speed and direction, of air density, and of extreme events). The third set addresses legal aspects: overview of legal evolutions during 2023, discussion of ways to find solutions to debates between protectors of biodiversity and renewable energy producers, and conflictual relationships between the lawmaker and wind turbines
