Andy Karsner is a highly influential entrepreneur, investor, diplomat, and strategist working to transform the world’s energy systems.In June, he was voted onto ExxonMobil’s board by activist shareholders as a way to hold the oil giant accountable on climate change.Back in the 90s, Andy was developing large gas and diesel power plants. But then he found the wind business. Andy started a company called Enercorp, which developed some of the earliest large-scale wind farms around the world.In 2005, Andy was chosen by President George W.
