Here we present the 93 global billionaires who have made their fortune (or at least a good chunk of it) in the energy industry. We cast a big net in order to capture everyone from Elon Musk, whose Tesla Motors is building new battery technologies, to Warren Buffett, whose Berkshire Hathaway operates power plants. These energy billionaires include 41 Americans and 18 Russians, while their ages range from 33 for Vladimir Putin’s son-in-law Kirill Shamalov to 100 for Standard Oil heir David Rockefeller. Whether it’s oil sands, wind turbines, pipelines, coal, solar, trading and deal making, these tycoons control more than $400 billion in global capital. How many have you heard of?
