I get the feeling Musk is pitching this whole "Green" energy challenge to create a demand for his "Power Wall" or the batteries that are being manufactured in his factories, because Solar and Wind generators goes hand in hand with electric batteries. (small scale)
Musk never say or do something without some hidden agenda, so I too will not be surprised if he plans to develop some "Green" solution for this fabricated problem. (He might already have hired some Crypto developers to develop a MuskCoin and to link that to his "Power Wall" or something under development.)
Sometimes me poop is green, if I run an antminer s-12 ( low power, older model ), would I meet the "Musk Seal of Approval" for "Green", inquiring minds got to know.
If I mine on st-paddy's day? Dress in green? Will that work?
Mine in Ireland?
Brown ( drought, lack of water, dead plants ) is the new Green in California&Texas (new home of Musk), will he play the brown card, and put down the green card?
While I know his electric EV's are hardly green given Lithium mining is terrible pollution, and all the electricity is most coal burning out of sight&mind. Then of course his rockets, where each launch is what? Something like 10k auto's in a year, burns the same fuel as a rocket-engine escaping the earth's gravity.
Musk is about as Green as my feces on a normal day. But hell the 'green talk' has gotten him ten's of billions of free tax money. Bullshit works in the USA, works well.
