Balancing renewable energy costs and optimizing energy mixMon, 13 Oct 2014 09:04:47 EDT
Increasing reliance on renewable energies is the way to achieve greater carbon dioxide emission sustainability and energy independence. As such energies are yet only available intermittently and energy cannot be stored easily, most countries aim to combine several energy sources. Scientists have now come up with an open source simulation method to calculate the actual cost of relying on a combination of electricity sources. 2014 Nobel Prize in Physics: Invention of efficient blue light-emitting diodesTue, 07 Oct 2014 07:17:41 EDT
The 2014 Nobel Prize in Physics has been awarded to Isamu Akasaki, of Meijo University in Nagoya and Nagoya University, Japan; Hiroshi Amano, of Nagoya University, Japan; and Shuji Nakamura of the University of California, Santa Barbara, CA, USA "for the invention of efficient blue light-emitting diodes which has enabled bright and energy-saving white light sources." Low-carbon energy future is clean, feasibleMon, 06 Oct 2014 15:21:26 EDT
A future where electricity comes mostly from low-carbon sources is not only feasible in terms of material demand, but will significantly reduce air pollution, a study says. Batteries included: A solar cell that stores its own powerFri, 03 Oct 2014 06:43:36 EDT
Is it a solar cell? Or a rechargeable battery? Actually, the patent-pending device is both: the world’s first solar battery. Scientists have succeeding in combining a battery and a solar cell into one hybrid device. Blades of grass inspire advance in organic solar cellsTue, 30 Sep 2014 14:42:58 EDT
Using a bio-mimicking analog of one of nature's most efficient light-harvesting structures, blades of grass, an international research team has taken a major step in developing long-sought polymer architecture to boost power-conversion efficiency of light to electricity for use in electronic devices.
