Solar is expensive at the moment, but that could change rapidly. David Biello writes in Scientific American yesterday:

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.”

Hm, so maybe Ray Kurzweil is right.

DoE Secretary Chu even thinks we could win something else:

“Just because we lost the lead doesn’t mean we can’t get it back,” Chu said. “We still have the opportunity to lead the world in clean energy…but time is running out.”

Meanwhile, we could shift fossil fuel subsidies over to solar and get on with it.
