Tens of thousands of blades of wind turbines must be replaced each year, and most have nowhere to go, as they can’t be reused. However, the industry is working on a green solution to wind power’s dirty downside.
Texas and Iowa, already leaders in the field, installed more wind turbines than ever last year.
The country as a whole installed 9.1 gigawatts of wind power in 2019, the most since the expiration of federal tax credits triggered a building boom almost a decade ago.
That wind power is generated via massive fiberglass blades, each of which can be longer than a Boeing 747 wing. Built to withstand hurricane-force winds, the blades can’t easily be crushed - or recycled or repurposed for that matter.
It’s a curious conundrum: Tens of thousands of blades must be replaced each year and most have nowhere to go but landfills like the one below. But the industry is working on a green solution to wind power’s dirty downside.
Legendary investor Jeremy Grantham last year announced he was devoting almost his entire fortune, more than US$1 billion, to fighting climate change.
In a new interview, he warned that the impacts are “accelerating.”
