Improved structural support for wind turbines could lead to 100% greater efficiency
(Phys.org)—A University of Cambridge's Department of Engineering study suggests that offshore wind farms could be 100 per cent more efficient in terms of energy payback if manufacturers embraced new methods ...
Japan finds rich rare earth deposits on seabed
Japanese researchers said Thursday they have found a rich deposit of rare earths on the Pacific seabed, with reports suggesting it could be up to 30 times more concentrated than Chinese reserves.
Oil drilling technology leaps, clean energy lags
Technology created an energy revolution over the past decade—just not the one we expected. By now, cars were supposed to be running on fuel made from plant waste or algae—or powered by hydrogen or cheap ...
When the wind blows: New wind energy research focuses on turbine arrangement, wind seasonality
(Phys.org) —Research into the best ways to arrange wind turbines has produced staggering results—quite literally.
Mars tech electrifies Earth
Some of the wind turbines generating electricity on Earth today grew out of technology developed in the 1990s for settlements on Mars.
Shifting winds in turbine arrays
Researchers modeling how changes in air flow patterns affect wind turbines' output power have found that the wind can supply energy from an unexpected direction: below.
Norwegian energy groups to build new British wind farm
Norwegian energy companies Statoil and Statkraft said Tuesday they will build an offshore wind farm in Britain with 67 turbines that will eventually power over 400,000 homes.
Gold rush-era discards could fuel cellphones, TVs (Update)
(AP)—Across the U.S. West, early miners digging for gold, silver and copper had no idea that one day something else very valuable would be buried in the piles of dirt and rocks they tossed aside.
Turning plastic bags into high-tech materials
University of Adelaide researchers have developed a process for turning waste plastic bags into a high-tech nanomaterial.
'Japan plans $16 bn aid package for greenhouse-gas cuts'
Japan's public and private sectors will supply an aid package worth $16 billion over three years to help developing nations cut greenhouse-gas emissions, a report said Tuesday, as climate talks get underway ...
Researchers developing high-flying jet car
It's dark and late. You're speeding through the streets of a downtown metropolis. You're being chased and the pursuers are quickly gaining ground. With a knowing smile, you simply press the 'launch' button ...
New hybrid technology set to change the future of renewables
A new hybrid technology that integrates wind and solar power generation is set to overcome many of the problems associated with traditional renewable power systems and revolutionise the green energy sector.
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.
Using fluctuating wind power
Incorporating wind power into existing power grids is challenging because fluctuating wind speed and direction means turbines generate power inconsistently. Coupled with customers' varying power demand, many ...
