Meet the Champions of Clean Tech
Microsoft icon and multi-billionaire philanthropist Bill Gates is a selective clean tech investor. “It’s crazy how little we are funding this energy stuff,” he told the Wall Street Journal last February. But he also understands what’s holding investors back. High-profile flops like those of Fisker and Solyndra have done little to assuage the doubts of investors--who, after all, want a return on their investment. Still, the successes do exist, according to Gates. He has personally invested in a handful of renewable energy start-ups over the past year, including the battery company Aquion Energy and algae fuel producer Sapphire Energy.
