Arguing that solar panels + batteries can provide energy to 8B people using modest space is like arguing that Rolls-Royces can transport 8B people using modest space. Yes, there’s *space* for 8B Rolls-Royces—but the human *time* it would take to produce them is cost-prohibitive. — PolitiTweet.org

The focus by @elonmusk and others on the *space* taken up by solar panels and batteries dodges the real issue: cost-effectiveness. Due to stratospheric battery storage costs, no amount of solar panels can *cost-effectively power* the world. — PolitiTweet.org

Another reason the world can’t be powered by solar panels and batteries: these only provide electricity—currently 1/5 of the world’s energy. Electricity can’t power many uses of energy (flight, cargo ships) and is very costly for others (many forms of industrial process heat). — PolitiTweet.org
