The wind turbines become the secure source. Once one flies across the USA and realizes how damn many of those things have been planted over the years, you realize there is no real shortage of material, regardless of what China does. There are pleeeeeenty of idle turbines, plenty. Most of them are not generating enough power to bother keeping them. Peak power happened during the most active turbine building phase.<br>
