By the end of the decade, U.S. manufacturers could make solar panels  that are less than half as expensive as the ones they make now.
At  52 cents per watt, that would be cheap enough for solar power to  compete with electricity from fossil fuels, according to a new study by  MIT researchers in Energy & Environmental Science. Assuming  similar cost reductions for installation and equipment, solar power  would cost six cents per kilowatt-hour in sunny areas of the U.S. — less  than the 15 cents per kilowatt-hour average cost of electricity in the  U.S. today.
Improvements would include an alternative to the  wasteful process now used to make silicon wafers, methods of handling  thin wafers to avoid breaking,  installation cost-reduction, and  improved light absorption, such as using nanostructured layers.

Cleaner, Cheaper Liquid Fuel from Coal - Technology Review
A new conversion process promises zero carbon emissions during production—but some question whether it will scale.
SRI International is  developing a process that combines coal and natural gas to produce  liquid transportation fuels that are substantially cleaner and cheaper  to make than existing synthetic fuels.
SRI claims its process addresses three liabilities that have slowed  the commercialization of the technology. By blending some natural gas  into the conventional coal-to-liquids (CTL) process, the private  research lab, based in Menlo Park, California, claims to have eliminated  CTL’s carbon footprint, slashed water consumption by over 70 percent,  and more than halved its capital cost.
