Solar takes the lead as wind lags in 2013 (US) installs

The first look at comprehensive data on energy generation infrastructure added in the United States in 2013 shows a big jump in solar, a massive decline in wind, and natural gas dominant.

Understanding the wind-solar connection

Construction of a big New Mexico array that will provide some of the cheapest electricity ever under contract from solar photovoltaics is “well underway” and expected to be completed in May, according to the state’s land commissioner.

Report: Wind and rain belts to shift north as planet warms

As humans continue to heat the planet, a northward shift of Earth's wind and rain belts could make a broad swath of regions drier, including the Middle East, American West and Amazonia, while making Monsoon Asia and equatorial Africa wetter, says a new study in Proceedings of the National Academy of Sciences.

How much energy is required to store wind and solar power on the grid?

Renewable energy holds the promise of reducing carbon dioxide emissions. But there are times when solar and wind farms generate more electricity than is needed by consumers. Storing that surplus energy in batteries for later use seems like an obvious solution, but a new study from Stanford University suggests that might not always be the case.

Big Data analytics projects sees more wind

Making wind and solar power – with their here-one-minute and gone-the-next tendencies – more reliable grid contributors usually leads to a discussion of energy storage.

Report: Wind, not water, formed mysterious mound on Mars

A roughly 3.5-mile high Martian mound that some scientists suspect preserves evidence of a massive lake might actually have formed as a result of the Red Planet's famously dusty atmosphere.

Lithium-polysulfide battery helps solar and wind power the grid

Researchers from the U.S. Department of Energy’s (DOE) SLAC National Accelerator Laboratory and Stanford University have managed to design a low-cost, long-life battery that could enable solar and wind energy to become major suppliers to the electrical grid.

Obama approves giant solar, wind projects in desert

Big solar was the biggest driver in the record-breaking U.S. solar gains made last year, with utility-scale plants accounting for more than half – 1,752 megawatts – of the 3,313 MW of newly installed capacity.

Geothermal to inch forward in 2013

A story popped up in my “geothermal power” feed on Sunday with the headline: “DOE set to award 4 renewable energy contracts.”

Wind could feed world's total energy demand

There's enough power available in winds to meet the whole of the world's energy demand, says a Carnegie Institution for Science report.

On wind, Obama sees a clean energy winner

A funny thing happened on the way to Solyndra becoming the dominant clean energy issue of the 2012 presidential campaign: It got blown away.

US Army kicks off $7 billion clean power gold rush

The U.S. Army is driving a huge new market for renewable energy, dangling up to $7 billion to purchase power sourced from solar, wind, biomass, geothermal and other alternative-energy technologies.

Plastic debris found littering ocean

There's far more little bits of plastic in the ocean than previous studies have indicated, according to new research.

Sustainable batteries take a swig of brown liquor

Everyone knows it: to take full advantage of solar and wind resources, we need to develop better ways to store the power they produce.

Wind, solar sought for epic NY trash heap

New York City is a big city, and it's been big for a long time - long enough to create, and close, a huge landfill, known as Fresh Kills. 

More clean energy doesn't mean less dirty energy

We like to assume that producing a new megawatt-hour of electricity from wind means we've eliminated a megawatt-hour of fossil-fuel produced electricity. 

US Army once again turns to clean energy

Last Fourth of July weekend, the U.S. Army‘s Tank Automotive Research, Development and Engineering Center (TARDEC) in Warren, Michigan experienced a power outage that halted operations of its laboratories.

DOE hub gets $120M to build a better battery

So, increasingly, we've got this whole renewable energy thing going on. But integrating all that new solar and wind power into the power grid remains a challenge. 

Renewables will bring golden age of free energy

Most people understand that once solar panels are paid off, the energy they provide is free. But what about on a national level? 

How solar, wind can pay to play

Are big solar and wind – like oil and gas – ready to compete to use resources on federal lands?
