Fossil-fuel emissions unbraked by financial crisis

Emissions of carbon dioxide (CO2) from fossil fuels and the cement industry scaled a record high in 2010, rocketing by 5.9 percent over 2009 in a surge led by developing countries, scientists reported on Sunday.

Geoengineering could save Earth -- or destroy it

(AP) -- Brighten clouds with sea water? Spray aerosols high in the stratosphere? Paint roofs white and plant light-colored crops? How about positioning "sun shades" over the Earth?

France launches vast solar panel array

France on Thursday launched its largest-ever solar energy farm, with an array of panels spread over about 200 hectares (500 acres) in the mountainous southern Alpes-de-Haute-Provence region.

Optofluidics could improve energy applications

(PhysOrg.com) -- The ability to manipulate light and fluids on a single chip, broadly called "optofluidics," has led to such technologies as liquid-crystal displays and liquid-filled optical fibers for fast data transfer. ...

Hybrid solar system makes rooftop hydrogen

While roofs across the world sport photovoltaic solar panels to convert sunlight into electricity, a Duke University engineer believes a novel hybrid system can wring even more useful energy out of the sun's rays.

NTT DoCoMo plans green-energy cellphone masts

Japan's largest mobile phone operator, NTT DoCoMo, plans to start powering its cellphone tower network with renewable energy such as solar, wind or biomass, the company said Friday.

Gasoline from water, CO2 and sunlight

A research team from ETH Zurich, PSI, and Caltech demonstrates the stable, efficient and rapid generation of solar fuels. They apply a thermochemical cycle based on ceria redox reactions to thermochemically split water and ...
