Pour sortir de la propagande verte et de ses « vérités » approximatives sur l’énergie éolienne je vous recommande de lire le papier professionnel de Jean-Pierre SCHAEKEN WILLEMAERS paru sur le site de l’Institut Thomas More.
On peut y lire par exemple:
« The fact is that wind energy is not at present as clean and CO2 emission free as their supporters suggest. Indeed the introduction of wind power in the conventional energy systems requires, inter alia, reserve capacity and back up thermal power stations where hydropower or other “green” energy is not or not sufficiently available, to secure the electricity supply in case of low wind or lack of it. Those power stations have to operate at lower load capacity and thus at lower efficiency to make room for wind generation and are ramped up and down according to wind conditions. All that increases the heat rate and hence GHG emission. So far, the claim that onshore large wind farms strongly contribute to CO2 emission reduction, has not been substantiated by analysis based on measured data in spite of the fact that such
survey is of the essence to justify costly financial support schemes for not always mature renewable electrical generation. »
ou encore:
« A problem with massive subsidization of renewable energy is that a number of developers/investors focus on maximizing the return on investment and not on long term operation with, as a consequence, minimizing the O&M (operation and maintenance) costs. On the equipment supply side, the policy of too many manufacturers is to enhance sales at all costs without taking sufficiently into account the after sales services. This leads, among others, to long delivery times of spare parts which makes O&M very difficult. Sales top, Service flop! In such conditions, what is the lifetime of wind turbines: 10 years or less?
