Google discloses carbon footprint, renewable energy goals

Google has been playing an interesting role in renewable energy development, and not only because it has invested more than $780 million in renewable energy generation and tech development.

Artificial light-harvesting method achieves 100% energy transfer efficiency

(PhysOrg.com) -- In an attempt to mimic the photosynthetic systems found in plants and some bacteria, scientists have taken a step toward developing an artificial light-harvesting system (LHS) that meets one of the crucial requirements for such systems: an approximately 100% energy transfer efficiency. Although high energy transfer efficiency is just one component of the development of a useful artificial LHS, the achievement could lead to clean solar-fuel technology that turns sunlight into chemical fuel.

Who will win the clean energy race?

Germany now has more renewable energy installed than the USA. But the race is far from over and there is stiff competition in developing countries.

While you're up, print me a solar cell [video]

The sheet of paper looks like any other document that might have just come spitting out of an office printer, with an array of colored rectangles printed over much of its surface. But then a researcher picks it up, clips a couple of wires to one end, and shines a light on the paper. Instantly an LCD clock display at the other end of the wires starts to display the time.

Double solar world record

(PhysOrg.com) -- A world record double by UNSW solar cell researchers promises to make solar power more affordable, with world-beating new technology delivering substantial efficiency gains at minimal extra cost.

Google invests $280 million in partnership with Solarcity

When Google throws its considerable influence into a new arena, people tend to notice. When that influence comes with $280 million, well, people may start to act.
