Energies renouvelables : éoliennes et panneaux solaires sont de plus en plus performants

Energies renouvelables : éoliennes et panneaux solaires sont de plus en plus performants

Les énergies renouvelables commencent à prendre le pas en matière de politique énergétique et il était temps à l’heure où le réchauffement climatique se fait de plus en plus sentir. Elles sont mises en avant par les multinationales comme Google ou Renault et les gouvernements œuvrent, à différents niveaux, à leur développement. Au total, 157 milliards d’euros ont été injectés dans les énergies renouvelables à l’échelle planétaire en 2010. Il aura fallu près de trente années de travaux pour élaborer éoliennes et panneaux solaires aptes à être commercialisés mais le chemin est encore long pour qu’elles atteignent leur rendement maximal, cette industrie étant finalement assez jeune.

Les premières éoliennes n’ont pas su résister à certaines tempêtes, d’autres ont vu les insectes se cumuler sur leurs pales ralentissant alors leur production énergétique et beaucoup ont été responsables du décès de bon nombre d’oiseaux. Les débuts ont donc été difficiles mais les éoliennes ont connu de grandes évolutions. Le producteur danois Vestas a par exemple conçu une éolienne trois cents fois plus performante que celles commercialisées il y a seulement quinze ans. Une éolienne offshore d’une capacité de sept mégawatts avec un rotor d’un diamètre de 164 mètres (!) étant actuellement en projet.

Des études pour optimiser au mieux leur rendement vont également être entreprises. Savoir où elles doivent être implantées et quelles améliorations peuvent y être apportées pour qu’elles résistent davantage aux caprices de Dame Nature en seront les grandes lignes de réflexion. Vestas prévoit également de travailler sur un système qui permettra de réduire considérablement les interférences entre les éoliennes et les installations radars, civiles ou militaires.

Du côté du secteur de l’énergie solaire, l’innovation est également permanente. La majorité des matériaux utilisés pour la conception de panneaux photovoltaïques sont difficilement recyclables et les cellules employées n’offrent un rendement que de 15% à 18% en moyenne pour les plus performantes. Mais des chercheurs sont parvenus à obtenir des rendements de 35% à 40% en utilisant de nouveaux éléments chimiques plus performants (NDLR : du gallium-indium et du germanicum). Des études sont également entreprises pour utiliser des pigments naturels pour imiter la photosynthèse et accroître le rendement des cellules photovoltaïques.

La firme Mitsubishi Chemical a quant à elle développé une technologie permettant de vaporiser, tout comme on peut le faire avec des bombes de peinture, des cellules photovoltaïques sur des bâtiments et même sur des châssis de voiture. Pour l’heure même si le produit est encore à l’état de projet, les cellules fabriquées à base de carbone pourraient générer de l’électricité en réaction à la lumière. Commercialisé d’ici 2013, ce spray aurait un rendement pratique de près de 10%.

Les énergies renouvelables devraient donc continuer à nous surprendre dans les années à venir et devenir de plus en plus efficace à des prix toujours plus raisonnables. Une nécessité pour faire face à l’urgence climatique.
