It happened when corporations that were keeping wind turbines in the corporation instead of selling them, stated selling.
the corporations had a setting, turned on by their owners, probably by mistake, when they contracted the products to the country.
I wrote about it here, two or three weeks ago.
everyone was complaining that wind turbine corporations were not selling their products.
now they do as we try to prevent these corporations from bankrupting and they all started selling the products they kept behind.
I am not sure the oversupply will last very long but huge shortages are probably gone.
