Fully renewable electricity could be competitive

(Phys.org) —A carbon price of between $50 and $100 per tonne of carbon dioxide would make coal-fired and gas-fired power less economical than renewable electricity, a UNSW study shows.

Virtual power plants for renewable energies

Siemens recently put two virtual power plants into operation. Virtual power plants are networks of several small power stations that are run like a single system. One of the new virtual power plants enables the Munich municipal ...

E-textiles get fashion upgrade with memory-storing fiber

The integration of electronics into textiles is a burgeoning field of research that may soon enable smart fabrics and wearable electronics. Bringing this technology one step closer to fruition, Jin-Woo Han and Meyya Meyyappan ...

Laser-powered rover to explore moon's dark shadows

A laser light shone through the dark could power robotic exploration of the most tantalizing locations in our solar system: the permanently-shadowed craters around the moon's poles, believed to be rich in water ice and other ...

Research uses mirrors to make solar energy cost competitive

If the current national challenge to make solar energy cost competitive with other forms of energy by the end of this decade is met, Ranga Pitchumani, the John R. Jones III Professor of Mechanical Engineering at Virginia ...

Clean energy least costly to power America's electricity needs

It's less costly to get electricity from wind turbines and solar panels than coal-fired power plants when climate change costs and other health impacts are factored in, according to a new study published in Springer's Journal ...

Development of handy fuel cell system

Researchers at AIST, Japan, have developed a handy, portable fuel cell system. While the developed system employs microtubular solid oxide fuel cells (microtubular SOFCs), a nanostructure-controlled electrode has enabled ...
