Metal-mining bacteria are green chemists

Thu, 02 Sep 2010 05:00:00 EDT
Microbes could soon be used to convert metallic wastes into high-value catalysts for generating clean energy, say scientists.

Off-the-shelf dyes improve solar cells

Wed, 01 Sep 2010 08:00:00 EDT
Scientists report success in boosting the ability of zinc oxide solar cells to absorb visible light simply by applying a blended mixture of various off-the-shelf dyes commonly used in food and medical industries -- in a soak-then-dry procedure not unlike that used to color a tee-shirt in a home washing machine.

A decade of studying the Earth's magnetic shield, in 3-D

Wed, 01 Sep 2010 02:00:00 EDT
Space scientists around the world are celebrating ten years of ground-breaking discoveries by "Cluster," a mission that is illuminating the mysteries of the magnetosphere, the northern lights and the solar wind. Cluster is a European Space Agency mission, launched in summer 2000. It consists of a unique constellation of four spacecraft flying in formation around Earth, studying the interaction between the solar wind and the magnetosphere.

Can the world be powered mainly by solar and wind energy?

Wed, 25 Aug 2010 08:00:00 EDT
Continuous research and development of alternative energy could soon lead to a new era in human history in which two renewable sources -- solar and wind -- will become Earth's dominant contributor of energy, a Nobel laureate said at a conference.

Americans using less energy, more renewables

Tue, 24 Aug 2010 14:00:00 EDT
Americans are using less energy overall and making more use of renewable energy resources. The United States used significantly less coal and petroleum in 2009 than in 2008, and significantly more wind power. There also was a decline in natural gas use and increases in solar, hydro and geothermal power, according to the most recent energy flow charts.

Self-cleaning technology from Mars can keep terrestrial solar panels dust free

Mon, 23 Aug 2010 11:00:00 EDT
Find dusting those tables and dressers a chore or a bore? Dread washing the windows? Imagine keeping dust and grime off objects spread out over an area of 25 to 50 football fields. That's the problem facing companies that deploy large-scale solar power installations, and scientists have now developed a possible solution -- self-dusting solar panels -- based on technology developed for space missions to Mars.

Scientists outline a 20-year master plan for the global renaissance of nuclear energy

Thu, 12 Aug 2010 20:00:00 EDT
Scientists outline a 20-year master plan for the global renaissance of nuclear energy that could see nuclear reactors with replaceable parts, portable mini-reactors, and ship-borne reactors supplying countries with clean energy, in new research.
