I think that solar IS the worlds leading energy source! Positive, actually. At least for all practical reasons/purposes, all usable energy comes from the sun. As an extension, solar is also the LEADING electrical source. It is, right now leading the way to our future ability to sustain modern technological civilisation.
Pv, direct thermal solar, wind energy and hydroelectric power are all driven by incoming solar energy. There is no escaping the solar system, and one of the best nuclear power reactors ever made is a more comfortable, 96 million miles distant!
