Solar and wind energy may stabilise the power grid

(Phys.org)—Renewable energies such as wind, sun and biogas are set to become increasingly important in generating electricity. If increasing numbers of wind turbines and photovoltaic systems feed electrical energy into ...

Microgrids: So much more than backup energy

(Phys.org)—Most Americans don't have to think much about energy reliability. We plug in a computer and it powers up; we flip a switch and the lights come on.

Superconducting cables for electricity grids

Power grids around the world are reaching their limits at the same time that electricity demand is growing. European researchers developed and tested one of the first superconductor-based cables to address the issue.

Grid stability thanks to precise forecasts

A self-learning software system from Siemens can stabilize power grids. The program, which is based on neural networks, can forecast the electrical output of renewable energy sources over a 72-hour period with more than 90 ...

Grid realities cancel out some of wind power's carbon savings

(Phys.org) -- Wind energy lowers carbon emissions, but adding turbines to the current grid system does not eliminate emissions proportionally, according to a report by researchers at the Argonne National Laboratory.

Sci-fi no longer, NREL engineers smart homes

Thanks to TV shows such as The Jetsons and Star Trek, many Americans grew up dreaming that homes of the future would be equipped with fantastic high-tech features. From automatic food dispensers to sliding doors, to Rosie ...
