GE: a busy bee with turbines and towers
Looks like GE’s been busy lately. But for one of the world’s largest companies that in itself is nothing new.
How loud is a wind turbine?
Because wind turbines are such a great source of clean, renewable energy, they’re usually greeted with a great deal of enthusiasm. But some complaints have been made that they can cause too much noise for residents living within a mile of the blades.
88-MW Wintering Hills Project: Alberta, Canada
The Wintering Hills project in Alberta is part of a new “crop” of wind farms being built across Canada. At peak operation, the wind farm is expected to generate enough clean electricity to power approximately 35,000 Canadian homes. The 88-MW project is located near Drumheller, approximately 125 km (78 miles) northeast of Calgary. Suncor Energy,…
Who’s offshore?
Many companies exhibited their offshore inventory at the AWEA conference in Atlantic City earlier in October. Here’s a look at a few and what they have to offer. Vestas V112 3.0-MW offshore turbine The V112-3.0MW Offshore is designed to take full advantage of wind conditions at sea. It’s well suited for high offshore wind speeds…
4-MW offshore turbine
After six years of working on the Irish Arklow offshore wind farm, General Electric felt it had gathered enough experience to develop a new model. The company’s 4-MW offshore wind turbine is built around a permanent magnet generator, delivering high efficiency at low wind speed. Two main bearings transfer axial and bending loads from the rotor to the bedplate,…
Turbines save $3M in diesel for Alaska’s Kodiak Island
