Electric-car Nemesis at top speeds is record-breaker
Spanish downturn a disaster for green energy
Spain's wind turbine manufacturers are laying off workers and farmers who installed solar panels are facing ruin as austerity policies afflict the long-coddled green energy sector.
Delft professor puts kites high on list for renewable energy
Study suggests real-world generating capacity of wind farms at large scales has been overestimated
Research by Harvard professor David Keith suggests that the global capacity for energy generation from wind power has been overestimated, and that geophysical / climate effects of turbines will reduce the ...
Toward super-size wind turbines: Bigger wind turbines do make greener electricity
In a study that could solidify the trend toward construction of gigantic windmills, scientists have concluded that the larger the wind turbine, the greener the electricity it produces. Their report appears ...
New inexpensive, efficient catalysts offer viable way to store and reuse renewable energy
Two University of Calgary researchers have developed a ground-breaking way to make new affordable and efficient catalysts for converting electricity into chemical energy.
On-site fabrication process makes taller wind turbines more feasible
Wind turbines across the globe are being made taller to capture more energy from the stronger winds that blow at greater heights.
Blackbird cart runs with wind only twice as fast
Obama carbon rule: Surprise winners, losers
Companies that generate electric power with anything other than coal—and companies that produce cleaner fuels or efficiency technologies—are likely to benefit from the Obama Administration's new proposed ...
Scientists spark new interest in the century-old Edison battery
Stanford University scientists have breathed new life into the nickel-iron battery, a rechargeable technology developed by Thomas Edison more than a century ago.

Wind energy: On the grid, off the checkerboard
As wind farms grow in importance across the globe as sources of clean, renewable energy, one key consideration in their construction is their physical design—spacing and orienting individual turbines to ...
Engineer says 'smart grid' needed for shift to alternative energy
(Phys.org) —Electrical grids are balky beasts, and nobody knows that better than Stanford Assistant Professor of Civil and Environmental Engineering Ram Rajagopal. He grew up in Brazil, where no one took ...
Study determines best arrangement of tidal sails device
In the long sprint to find new sources of clean, low-cost power, slow and steady might win the race—the slow-moving water of currents and tides, that is. Just as wind turbines tap into the energy of flowing ...
