5 Powerful Facts for Global Wind Day

Union of Concerned Scientists

We at the Union of Concerned Scientists think a lot about wind power. In honor of Global Wind Day , here’s a roundup of what we’re seeing and what we’ve been thinking—five facts about wind energy to keep in mind as you celebrate, or at least make note, on June 15. Wind power is big, and getting bigger.

What Happens to Wind Turbine Blades at the End of Their Life Cycle?

Union of Concerned Scientists

While today’s carbon fiber and fiberglass require lots of energ y to produce and are hard to recycle , incorporating more bio-materials into their composites and developing new recycling technologies can reduce their footprint. For example, LM Wind Power has minimized balsa in its blades, substituting in synthetic plastic PET and PVC foams.

Wind power costs fell by half from 2008 to 2021. I don’t mean to imply that technological progress will automatically fix things. Fourteen states now have net-zero emissions targets for the economy as a whole, and sixteen have zero-carbon targets for the grid. Utility-scale solar was an even more dramatic story.
