The only angle about the Chinese…is that now they MAKE the solar panels. We don't have access to the "Reare Earth Elements" needed… MOST of those are mined in China…who now won't export the raw materials… as they have a virtul monopoly on Solar Panels. Even so… we have many reasons to want solar to become a higher % of energy. Had the Bundy clan..like other ranchers..PAID THEIR OWED FEES.. there's no problem. Actually an oil company nearly sold the only US mine it owned, to the Chinese a few years back. Molycorp | Molycorp?s History […]
