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 ...
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.
Island channel could power about half of Scotland, study shows
Renewable tidal energy sufficient to power about half of Scotland could be harnessed from a single stretch of water off the north coast of the country, engineers say.
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 ...
Best of Last Week – quantum information accurately transfered, better wind turbines and study of porn's impact on brain
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 ...
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 ...
GE has surgical technique to power up wind blades
How offshore wind turbines could be more efficient
A Cambridge University study suggests that offshore wind farms could be 100 per cent more efficient in terms of energy payback if manufacturers embraced new methods for making the structures that support ...
Wind map shows untapped energy potential in cities
Putting a wind turbine on your suburban home may leave you disappointed but there is a large untapped wind energy potential in UK cities, say scientists. A new study has mapped the wind energy potential of ...
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 ...
