Meet the Champions of Clean Tech

Peter Thiel

Paypal co-founder and philanthropist Peter Thiel probably wouldn’t describe himself as a “clean tech crusader”--in fact, the billionaire has been one of the sector’s most vocal skeptics. Yet Thiel sank more than $37 million into the renewable energy company LightSail last year. “For far too long, the clean tech industry has been driven by politicians and ideologues who trade people’s taxes for dreams,” he wrote in a press release. “But hype is not a sustainable energy source. It’s time to find honest companies that can develop technologies that stand on real innovation.”
