DOE Drives Hydrogen Car Fueling Push
If fuel-cell vehicles are ever going to get anywhere, they’ll need places to fuel up, and the public-private H2USA initiative is aimed at developing the infrastructure.
Is There Hope For Hydropower As The Climate Changes?
As the world gets hotter everywhere, some areas get wetter, more drier, and extreme weather becomes more common, how will the potential of hydropower to generate renewable electricity change?
Floating Wind Turbines With Undersea Energy Storage
An MIT concept would connect deep-water wind turbines to concrete spheres at the seafloor that would take advantage of hydrostatic pressure to store energy.
When Renewable Energy Shoots Itself In The Foot
Ann Arbor should say no to spending a big wad of federal money to put up wind turbines that will produce little energy, EarthTechling’s Pete Danko says.
NC Renewable Energy Standard Scores Surprise Win
To the shock and horror of its backers, a bill attempting to gut North Carolina’s renewable energy standard fails in committee.
Wind Power Draws Facebook To Iowa
“An abundance of wind-generated power” is chief of among the reasons Facebook will build a new data center in Iowa, the company said.
Will We Ever Really Make Much Electricity From the Ocean?
It’s a very enticing idea, making electricity from the predictable motions of the sea. But will we ever really utilize it? And will it generate much power?
Geothermal Power: Electricity From Earth’s Untapped Potential
Geothermal power is an old renewable energy source, with a huge potential — especially if enhanced geothermal systems can be commercialized.
Ionic Wind Efficiency Thrusts Into Spotlight
MIT says new research suggests that thrusters powered by ionic wind could be an efficient alternative to conventional atmospheric propulsion technologies.
At Paris Marathon, Watts Of Energy Expended, Some Captured
Thousands of runners pounded the pavement – and Pavegen’s energy-harvesting panels – at the Paris Marathon on Sunday.
Storing Renewable Energy: Key To An All-Renewables Future
The all-renewables future will require energy storage. Here we explore both current possibilities and technologies that might one day be practical.
Hydrogen From Plants Touted As Game Changer
Hydrogen has its second “breakthrough” story in a week, with a new enzyme combination said to be remarkably efficient at extracting the gas from plants.
Desert Pumped Hydro Proposal Gets Scrutiny
A pumped hydro project at a former iron ore mine near Joshua Tree National Park is touted as a way to get more renewable energy on the grid.
