We’ve been writing about clean technology for a while now, but we haven’t articulated how Silicon Valley’s possible contributions to new energy sources can directly help foster world peace. Thomas Friedman, in today’s NYT, outlines an interesting argument along these lines. Not everyone will agree, and some environmentalists will take issue with his endorsement of nuclear power (which critics say creates a huge radioactive waste problem, sucks up subsidies, is more expensive than the industry sometimes owns up to, and leads to verification problems precisely in prickly places like Iran). Yet it’s worth mulling over. Of course, only a tiny fraction of the Silicon Valley’s venture capital investments are earmarked for energy related technologies, perhaps a sign of the limits to how much technology can produce alternative energy sources. Still, even if the opportunities are few, they are potentially huge.
