Pondering what human-made items will look like millions of year from now as our descendants search for “technfossils”, Sci News wondered what wind turbine blades would look like.

They said, “The enormous wind turbine blades . . . are made of materials like fiberglass and epoxy resin and carbon fibers, which are terribly hard to recycle — but easy to fossilize.”

“As wind turbines reach end-of-life and are decommissioned, huge landfills of the 50-m-long-plus blades, sliced into truck-length segments and neatly stacked side by side, are appearing and growing.”

“Some will stay buried for millions of years — and, if finally erosion-revealed and stumbled upon by some curious far-future paleontologist, will be an amazing sight, like a graveyard of gigantic, hollow, sawn-up bones.”

“And right now, we should begin to understand this amazing, if often toxic, legacy that we are leaving for the planet.”
