Getting a wind turbine to a decent height to allow it to reach stronger winds than those found closer to the ground generally means sitting them atop a tower. Despite the eco-credentials of wind turbines, these towers are usually constructed from steel, which is not only expensive, but requires large amounts of energy to process. In an effort to make wind turbines even greener, German company TimberTower has erected a wooden 1.5-MW wind turbine in Hannover, Germany.
