The world's first full-scale timber wind turbine has started turning in Sweden, with a tower built by wood technology company Modvion.
The 105-metre-tall tower, located in the region of Skara, is Modvion's first commercial wind turbine tower, and follows on from a smaller 30-metre-high demonstration project the company completed in 2020.
While its rotor blades and generator hub are made of conventional materials, the tower is made of laminated veneer lumber (LVL), a type of engineered wood made of thin veneer strips glued together and often used for beams and load-bearing building structures.

The company says that this type of wood is not only strong enough to withstand the forces of a turning turbine, it is much more environmentally sustainable to build with than the currently used steel. While wind power plays an important role in providing the world with green renewable energy, there are still ample carbon emissions created during their construction ? in part because of the steel towers.
Modvion describes its wood towers as reducing the carbon emissions from wind turbine construction by over 100 per cent, due to the combination of a less emissions-heavy production process and the carbon storage provided by trees.
"Our towers, just in the production of them, they emit 90 per cent less than a steel tower that will do carry the same work," Modvion chief financial officer Maria-Lina Hedlund told Dezeen...
