DOE, partners test commercial geothermal technology in Nevada
Geothermal energy attracts more and more attention, and for good reason: One cubic kilometer of hot granite at 250 degrees centigrade has the stored energy equivalent of 40 million barrels of oil

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

U.K. energy company to demonstrate its oxyfuel technology
Oxyfuel combustion is the process of firing a fossil-fueled power plant with an oxygen-enriched gas mix instead of air; oxyfuel combustion produces a CO2-rich flue gas ready for sequestration

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

Life of U.K. project aiming to halve cost solar panels extended
U.K. government agency injects £6 million into research aiming to halve the cost of solar photovoltaic (PV) cells; in the first four years of the project, scientists created platform technologies in crystalline silicon, thin film silicon, thin film cadmium telluride, and thin film copper indium diselenide; now they will narrow down the research
