So, why not just use batteries to store BigWind energy? Battery storage is simply not dense enough. Read below and you will see the limitations. It does not make sense. We need energy DENSE sources that are efficient, dispatchable and inexpensive (nuclear/gas/coal/hydro) for our homes and businesses. Batteries, though rechargeable, are not green. Visit a lithium mine in northern Chile(pic above). Texas would not permit such a facility, and consider trying to open one in California or Massachusetts. And keep in mind, that lithium, like lead and cadmium, also popular for batteries, is a poisonous heavy metal. This is another aspect of the fake news about new renewables. And consumers need a lot of mines and batteries. A new battery for a full-size car stores 1 kWh. Running New York City for two cloudy, windless days would require about 530 million such batteries, about 62 per person….Read through the article(s) below and you will see that just 1 Tesla car battery uses 63 kg of lithium= more than the amount in 10,000 cell phones….
