Policy issues plague hydropower as wind power backup

Theoretically, hydropower can step in when wind turbines go still, but barriers to this non-polluting resource serving as a backup are largely policy- and regulation-based, according to Penn State researchers.

Getting the carbon out of emissions

Many researchers around the world are seeking ways to "scrub" carbon dioxide (CO2) from the emissions of fossil-fuel power plants as a way of curbing the gas that is considered most responsible for global climate change. ...

The 3-D printing revolution

"3-D printing"—the popular name for "additive manufacturing"—has been identified as one of the coming cluster of "disruptive" technologies. Expectations are that it will be a way—not the only way—to make all sorts ...

New battery design could help solar and wind power the grid

(Phys.org) —Researchers from the U.S. Department of Energy's (DOE) SLAC National Accelerator Laboratory and Stanford University have designed a low-cost, long-life battery that could enable solar and wind energy to become ...

Caltech engineers build electronic chips that repair themselves

Imagine that the chips in your smart phone or computer could repair and defend themselves on the fly, recovering in microseconds from problems ranging from less-than-ideal battery power to total transistor failure. It might ...

US power grid costs rise, but service slips

America's power grid is like an old car. It gets the job done, even if its performance is slipping. But the repair bills go up every year and experts say only a major overhaul will reverse its decline.

Carbon sponge could soak up coal emissions

Emissions from coal power stations could be drastically reduced by a new, energy-efficient material that adsorbs large amounts of carbon dioxide, then releases it when exposed to sunlight.
