A Towering Achievement: This Summer In Holland, GE Will Build The World’s Largest Wind Turbine

Tomas Kellner
January 18, 2019

Rotterdam’s famous windmills, cube houses, and tulip gardens will soon have to compete for attention with a towering newcomer. GE announced plans this week to erect a prototype of the world’s largest wind turbine, the Haliade-X, on the city’s outskirts. The turbine has a rotor that measures 220 meters in diameter — twice the length of a football field — and stretches 260 meters from its base to blade tips. That’s nearly three times the height of New York’s Statue of Liberty, measured from the ground to the tip of the torch.

Just Deserts: Oman's New Wind Turbine Can Handle Sandstorms And Desert Sun

December 28, 2018
When it comes to renewables, a hot desert can be an oasis for solar power, but there are two big reasons why wind farms rising among sand dunes were — until recently — just a mirage. “Heat and sand make it difficult for normal wind turbines to operate in the desert,” says Rebeca Calderon, a program manager at GE Renewable Energy in Barcelona.

GE cast the blades in a foundry, but Avio Aero, which wanted to go after the emerging TiAl market, bet on 3D printing. “We could see how difficult it was to make these blades,” Abrate says. “But we had positive experiences with 3D printing on a military project.”

All That Jazz: GE Opens Wind Turbine Blade Test Center At NASA Rocket Factory In New Orleans

There are few places in the world like NASA’s rocket factory in New Orleans, where the U.S. space agency and its contractors are building the Space Launch System. It’s the most powerful rocket ever designed — and may one day take astronauts as far as Mars. Known as the Michoud Assembly Facility, the plant covers an area equal to 31 American football fields, including several soaring high-bay areas where workers stack silver and orange rocket segments like Jenga blocks.

Wind Turbines Of Change: This New Wind Turbine Platform Is Creating Fresh Opportunities For Renewables Around The World

September 24, 2018
The capriciousness of the elements is a perennial challenge for intermittent renewable energy sources. The wind doesn’t always blow, and the sun hides behind clouds. While engineers may not be able to command the weather, they’re getting better at harnessing as much wind as possible by bringing wind turbines to blustery places where logistically it could not have been done before. A profitable wind farm nestled in a Japanese mountain valley or rising from the slopes of rugged Greek hills is now possible because of the combination of new technologies and skilled service crews.

Spin Doctors: How Software And Engineering Savvy Helps GE Squeeze The Most From A Fleet Of 900 Wind Turbines

September 06, 2018
Over 150 years ago, a budding English economist named William Stanley Jevons warned that a policy of energy efficiency might not be sufficient to conserve Britain’s dwindling coal reserves. His argument, now known as the Jevons paradox, was simple: Squeeze more energy from less coal, and people will just want more coal.

As wind whistles down the eastern slopes of the Rocky Mountains, it picks up a lot of speed. It’s not unheard of for gusts of up to 100 miles per hour to slam into the rolling green foothills just outside of Boulder, Colorado.

Blade Runners: A Look Inside A Factory For Giant Wind Turbine Blades

Every year, thousands of tourists travel to the northwestern corner of Castellón, a province on Spain’s Mediterranean coast, to visit some of Europe’s oldest and most plentiful cave paintings, dating back to the Stone Age. With rich images depicting archers hunting stags, boars and bears, as well as other scenes, the caves are now a UNESCO World Heritage site and have survived for millennia thanks to the area’s hot and dry weather — the same conditions that lured the world’s largest maker of blades for wind turbines to the area.

For The Record: GE Onshore Wind Turbines In North America Can Now Power The Equivalent Of 11 Million U.S. Homes

Iowa may conjure up images of sweeping cornfields dotted with farms, but this Midwestern state has been at the forefront of wind energy technology since 1983, when it became the first state to enact a renewable-energy mandate, requiring local investor-owned utilities to use wind or solar sources for power generation. In 2017, Iowa generated 37 percent of its electricity from wind, the largest share nationwide.
