> Solar is cheap. We are looking at an age of energy abundance. (*) for less than half a day, in areas that are sunny, "close" to the tropics. And arguably this is fine for the majority of the Earth's population because they do indeed live close to the tropics with 12 hrs of sunshine. On the other hand, the bulk of the first world economies that require vast amounts of energy are pretty far north where it's rainy, cloudy, and daylight can be as little as a couple of hours in the winter.
