If 1.8 million sq km of solar panels doesn’t seem like much, note that it is *more than all cities, towns, villages, and human infrastructure combined* (~1.5 million sq km). And this excludes the huge footprints of solar/battery mining, manufacturing, and transmission. — PolitiTweet.org

The world uses >165,000 TWh of energy per year, which requires ~19 billion kW of power output on avg. An optimistic, real-world power density for solar projects is 10 W/m^2. To power the world, you’d need ~1.8 million km^2 of solar PV projects—about the size of Libya. https://t.co/iCvwVPtIJT — PolitiTweet.org

Summary: While we are told that the world can be powered by a small area of solar panels + batteries, the storage costs involved are impossibly high (hundreds of $trillions) and the panels involved would take up more area than all the world’s cities, towns, and villages combined. — PolitiTweet.org
