The U.S. Department of Energy (DoE) aims to change that by bringing
down the cost of solar electricity via a new program dubbed “SunShot,”
an homage to President John Kennedy’s “moon shot” pledge in 1961.
“If you can get solar electricity down at [$1 per watt], and it scales
without subsidies, gosh, I think that’s pretty good for the climate,”
notes Arun Majumdar, director of the Advanced Research Projects
Agency–Energy (ARPA–e), the DoE’s high-risk research effort. “With
SunShot, the goal is to reduce the cost of solar to [$1 per watt] in
the next six years.”
The man who knows more about doubling rates than anyone else in the world
(he accurately predicted computers winning at chess and the Internet,
including the correct dates),
Ray Kurzweil, interviewed by Lauren Feeney on PBS:
One of my primary theses is that information technologies grow
exponentially in capability and power and bandwidth and so on. If you
buy an iPhone today, it’s twice as good as two years ago for half that
cost. That is happening with solar energy — it is doubling every two
years. And it didn’t start two years ago, it started 20 years ago. Every
two years we have twice as much solar energy in the world.
Think about how fast the Internet has grown in the 21st century.
That’s what he’s talking about: from unknown to TV news anchors
to facilitating multiple revolutions in weeks. He continues:
