Outside of making money on minor subsidies? Well, he is the one that brought banking to the net, which really allowed for commercialism on it;
He is one of, if not the, largest installer, and owner of solar. In addition, his new factory going up in new York should produce highest efficiency, lowest costs panels by end of 2017; his Tesla is the reason why electric vehicles are taking off. In fact, it is the shear fright of model 3 that caused Europe to walk away from their plans for hydrogen vehicles; and of course, spacex has singlehandley caused the price of rocket launches to plummet. Russians, Europeans, and American launch systems have had no choice but to drop their prices and get massive subsidies to compete against minor subsidized spacex.
But hey, I doubt you wanted facts here.
