One of the biggest obstacles of #greenenergy and fighting #climatechange is how difficult and expensive it is to mine things like #lithium and #cobalt for batteries in #electriccars and other green energy methods. One of the ways we can really fight climate change and #globalwarming is proliferation of various renewable energy sources and improve battery technology. Critics of electric cars fighting global warming often point out the difficulty and ultimately high carbon footprint of mining lithium, cobalt and other minerals. Since we can grow diamond and other gems in a lab, why can't we do the same with lithium and other minerals?
