00:00This wind turbine tower is built almost entirely out of wood.

00:05So why choose wood over traditional materials like steel or concrete or composites of both?

00:10It's carbon dioxide of course.

00:12And then it's also stronger by weight than steel.

00:15So that makes the transportation easier because you can transport more of them on the same transport.

00:23The advantage then I guess is that you can get them anywhere you want.

00:26Yeah.

00:27Most wind towers are built out of a combination of steel and concrete which emits tons of carbon dioxide during production.

00:35Using wood avoids all that and helps lock carbon away.

00:39Every single wind power tower is built to last as long as the technical components last.

00:45So nowadays you design them for 35 years but the wood itself can stand for much longer than that.

00:53So after decommissioning, some companies will cut it up, make it into beams, columns, use it for timber building.

01:01And then it will keep the carbon for hundreds of years more.

01:05And after that, maybe boards and in the end, paper.

01:09Oh, okay. So it's got afterlife after afterlife.

01:13Many afterlives.
