Scientists at the Duke University have developed a novel approach that they believe can help generate electricity from nature’s motion. Energy harvesting is the process of converting one form of energy, such as motion, into another form of energy, in this case electricity. Strategies range from the development of massive wind farms to produce large [...]

The company Sharp Corporation has developed the world’s highest solar cell conversion efficiency of 35.8% using a triple-junction compound solar cell. In comparison with silicon-based solar cells, the compound solar cell utilizes photo-absorption layers made from compounds consisting of two or more elements such as gallium and indium.

Two companies called Statkraft and Wetsus are trying to develop an alternative that provides low-cost renewable energy by harnessing energy from the sea water and clash of river.

Dahon has announced a new piece of equipment, the BioLogic FreeCharge , that attaches to your bike’s dynamo, granting you the opportunity to charge your electronic device through the USB port just by pedaling.

Scientists from the Cornell University have created the basic element of a solar cell made from carbon nanotubes, that proves to be more much more efficient at transforming the energy from the sun into electricity.

Eternaleds, Inc., which specialized in LED technology has developed a new set of LED light bulbs, the first of their kind to use a cooling technology which makes them 40 percent cheaper and that can be paid back in less than 2 years.

A “green” Jerusalem company called GreenSun has developed colorful solar panels that don’t need direct sunlight to work, capturing different parts of the sun’s light spectrum. The company claims that its highly-efficient solar panels will cost less than a dollar per watt to manufacture, in comparison with a conventional solar which cost more than $4 [...]

New Energy Technologies has developed an ultra-small solar cell that is capable to harvest artificial light which is in abundance in commercial skyscrapers and offices. New Energy’s solar cells installed in their transparent SolarWindow  generates electric energy by using the visible light in artificial fluorescent lighting typically installed in commercial buildings and offices .

Milan Karki, a young inventor who comes from a village in rural Nepal, has created a new type of solar panel made from human hair, which could provide the world with green and cheap electricity.

Researchers at the University of Washington have demonstrated that trees can generate electricity. For the beginning they have successfully powered tiny electrical circuits.
