SOLAR TO POWER THE WORLD
How many solar panels would it take to power Earth? What would a world powered by solar energy alone look like? According to one study, it would need to be enough solar panels to fill an area about the size of West Virginia.

“…According to a graduate thesis by Technical University of Braunschweig student Nadine May, the number of solar panels needed to supply the entire world’s energy needs would fill just 25,000 square miles – or an area only slightly larger than the state of West Virginia…If the amount of solar panels needed were divided evenly in every country, they would take up just 127.5 square miles in each…[T]hat would be asking a lot of smaller countries…So larger countries would have to host more panels – maybe even on a per-capita basis…The graphic places about a quarter of all panels in the baking hot Saharan Desert…[but the] more evenly distributed the panels are, the better; localization would help diversify infrastructure, reduce the inevitable power losses that occur over long transmission distances, and allow more countries to share the burdens of installation and maintenance…” click here for more
