<div class="slide">Wind energy is growing faster than any other type of renewable energy, according to 2021 data. But to reach net-zero emissions of planet-warming gases, global capacity still needs to double — which could mean a tsunami of turbine waste.

There are already more than 70,000 turbines in the US, according to the US Wind Turbine Database.
And with plans to expand offshore wind, the US could have 2,000 more within the next decade, Reuters reported.
On a global scale, a 2017 study predicts global waste from turbine blades will exceed 47 million tons by 2050.
