We visited the Chinese manufacturing site for TPI Composites, a wind company headquartered in Scottsdale, Arizona.
The 40 meter blades are part of turbines that are rated at 1.5 MW.
A picture of me next to the stem provides some sense of the size.
The process to manufacture seems far more labor intensive than producing solar.
As with solar, the wind industry is heavily dependent on policies enacted all over the world to encourage production.
There is a general sense of nervousness in both sectors on that governmental commitment.
