Solar energy conversion breakthrough
Scientists say that sunlight falling on only 9 percent of California’s Mojave Desert could power all of the U.S. electricity needs — if the energy could be efficiently harvested; this is a big “if,” since current-generation solar cell technologies are too expensive and inefficient for wide-scale commercial applications; Northwestern University researchers show a way to increase solar cell efficiency

King coal, II: Administration restructures approach to clean coal funding
DOE restructures FutureGen approach; under the new plan, DOE’s investment would provide funding for no more than the carbon capture and storage (CCS) component of the power plant — not the entire plant construction; the original 2003 FutureGen concept called for the federal government to cover 74 percent of the cost of the entire project; DOE requests $648 million in FY2009 budget for coal research, development, and deployment
