A German company has a novel product – wind turbine blades made from wood. A little recognized issue with wind energy is that the turbine blades only last 2 or 3 years and then they go to the landfill. — as many as 14,000 blades each year. Voodin Blades uses high-tech laminated lumber, that has similar characteristics to glass fiber, held together by a glue designed to work with wood. The blades can be reused or repurposed for construction or other products – or  burned. And they are biodegradable. They are also 20% cheaper than standard blades.
