Ray Kurzweil has made a bold prediction about the future of solar energy, saying in remarks at a recent medical technology conference that it could become the dominant force in energy production in a little over a decade. That may be tough to swallow, given that solar currently only supplies around 2% of global energy—but Kurzweil’s predictions have been overwhelmingly correct over the last two decades, so he’s worth listening to.
Kurzweil’s basic point, as reported by Solar Power World, was that while solar is still tiny, it has begun to reliably double its market share every two years—today’s 2% share is up from just 0.5% in 2012.
Many analysts extend growth linearly from that sort of pattern, concluding that we’ll see 0.5% annual growth in solar for the foreseeable future, reaching just 12% solar share in 20 years. But linear analysis ignores what Kurzweil calls the Law of Accelerating Returns—that as new technologies get smaller and cheaper, their growth becomes exponential.…Fortune
