South Carolina’s Clemson University dedicated what it calls the “world’s most advanced energy systems testing and research center. It contains an advanced wind turbine drivetrain testing facility, but it’s about much more than that. via Smart Grid: Clemson U. unveils new energy systems research and testing center.
Originally published on ABB Conversations. By Jari Pekka Matsinen. Approximately one-third of all wind turbine failures are somehow related to the electrical drivetrain Although the wind turbine looks quite simple, it is actually a complex...Show More Summary
UK-based New Wave Energy wants to equip drones with solar panels and wind turbines, creating a swarm of flying power plants above the clouds.
GE wins 545 MW of wind farm commitments in Brazil Steve Bushong, November 25, 2013 (Windpower Engineering & Development) "GE recently won 545 MW of orders for wind turbines in Brazil’s A-3 auction, which was held in mid-November. The...Show More Summary
Various promoters maintain the cost of wind energy is competitive with other sources of energy. This is not the case. The EIA calculates the levelized cost of NEW onshore wind turbine plants place in service in 2018, capacity factor 0.34, 30-yr life, at $86.6/MWh, including transmission of $3.2/MWh. read more
As you may recall, I got to write about GE’s new PowerUp platform from the launch event in Chicago just last month, and also got to conduct follow-up interview with GE CEO and Chairman Jeffrey Immelt and the head of GE Renewable Energy Services, Andy Holt. Show More Summary
IEEE SPectrum has an article on the increasing size of offshore wind turbines - Belgium Claims World’s Largest Offshore Wind Turbine. The largest offshore wind turbine on the planet is now spinning off of the coast of Belgium at the Belwind site. Show More Summary
And now, a Thanksgivukkah miracle for the birds: This week, Wind Capital Group announced that it will not move forward with the Sugarland Wind Farm, a project that would have placed 124 Statue of Liberty-sized wind turbines in the Everglades...Show More Summary
The six-megawatt turbine can produce 15 percent more power than competitors, and a big project with bigger turbines is cancelled
Vestas is leading an effort to bring hybrid power generation – systems that combine factory-refurbished wind turbines and what the company calls “advanced diesel power generation” – to the poor, beginning with as many as 13 projects in Kenya that could serve 200,000 people with electricity at 30 percent below the current cost of diesel-only power production. read more
This article was jointly written by one of CleanTechnica’s readers and Zachary Shahan. It’s a shame when a beautiful (or even an ugly) animal dies. It’s a shame that wind turbines do indeed kill birds. However, every source of electricity we have kills some number of birds. Show More Summary
By virtue of the way in which I watch TV, I rarely come across the latest in advertising until it’s well into the mainstream consciousness. So it is with no real surprise that I never saw this fantastic Apple iPad ad that aired last month. Show More Summary
In Scotland, developers have been cutting back on offshore wind deployment due to the high cost of it. The installation of wind turbines into the sea floor is part of this issue. But a long-waiting solution is floating wind turbines....Show More Summary
Engineers often take inspiration from animal designs because they're more efficient than machines are. In the case of owl wings, nature has a major advantage over human engineering: owl wings are uncannily quiet. Now, researchers are considering outfitting wind turbines with an upscaled equivalent – if they can figure out how to do it. Read more...

The world’s largest offshore wind turbine was recently installed in the waters near Ostend Harbour at the Belwind Wind Farm in Belgium. The 6 MW Haliade 150 wind turbine model, with 73 meter long blades and a 78 meter tower was built by the French company
Harvesting power from the wind and the sun is nothing new. We've seen flying wind turbines and solar power plants that aim to provide clean renewable energy. UK-based New Wave Energy has a bolder idea in the works. The company plansShow More Summary
The Obama administration is trying out new bird protection laws, pulling in a cool million in fines from an energy company responsible for murdering 14 golden eagles — a federal crime — with its wind turbines. Read more...
