Back In Black: At A German Wind Farm, Direct Current From The Company Edison Founded Makes A Comeback

The 1893 World’s Fair in Chicago was a high point in American history. The fair boasted the first Ferris wheel, the first moving walkways and the introduction of Pabst Blue Ribbon beer. But for many visitors, the highlight of the six-month-long event was the dazzling lights.
At night, the fair was lit by hundreds of thousands of incandescent bulbs. Although GE founder Thomas Edison had patented the light bulb 14 years earlier, no one had seen a light exhibit on the scale of the Chicago fair.

Tour De Force: This New Software Is Helping Digitize An Ancient Source Of Energy - Water

The city of Briançon sits in a mountainous corner of France that has become a popular destination for cycling fans, who flock to the punishing Tour de France stages there. But it may soon become a required stop for the energy geeks too.
That’s because a dam in the hills above the city recently started testing new software that allows the operators to monitor power generation in a new, revolutionary way.

Could This Be The Most Extreme Power Plant In The World?

Hidden away above the tiny Swiss Alpine town of Linthal, deep inside a snowcapped granite massif, sits Europe’s newest engineering marvel. It is a hydropower plant like no other, able to generate as much electricity as a nuclear power plant and, at the flip of a switch, act as a giant battery. “It’s the only grid-scale method of storing energy,” says Maryse François, the hydrotechnology leader at GE Renewable Energy, the company that developed the technology powering the site.

The Temple Of Turbine: One of These Wind Turbines Can Power 5,000 Homes

The French port of Saint-Nazaire lines the northern shore of the Loire estuary as the river empties its muddy waters into the Atlantic Ocean. The city may not be large, but the 70,000 people who live there are used to making very big things.
The world’s fastest and largest liners, including Normandie and Queen Mary 2, sprung from its dry docks. The port also serves as a transit hub for the fuselage and wings that make the double-decker Airbus A380, the world’s largest passenger aircraft.

This Massive Magnet Will Generate Power At America's First Offshore Windfarm

Tomas Kellner
March 20, 2016
Offshore wind farms can tap into a bounty of wind that allows them to work twice as productively. But that efficiency comes at a cost. Like any sea-based technology, wind farms are difficult to build and expensive to maintain, with workers fighting against the same weather that makes the farms work so well. As a result, terrestrial turbines have been steadily gaining ground compared to turbines built at sea. But that may soon change.

Nip & Tuck: Surgery Makes Wind Blades Go Bigger

May 19, 2014
Wind is growing up. A recent survey of the industry found the average size of commercial turbines has grown 10-fold in the last 30 years, from diameters of 50 feet in 1980 to nearly 500 feet today. Turbines with larger rotors harness more wind and generate more power “without proportional increases in their mass or the masses of the tower and the nacelle that houses the generator,” according to the report.

Wind, Solar and Other Renewables Added 40 Percent of All New U.S. Power Capacity Last Year. Here’s What Greased the Wheels

April 24, 2014
Last spring, the global renewable energy company Invenergy announced that it would install the first three “intelligent” wind turbines equipped with storage batteries and connected to the Industrial Internet at the Goldthwaite wind farm in Central Texas.

Power Couple: The Wind and the Cloud Make it Rain

February 14, 2014
Thomas Edison and Charles F. Brush were born just two years and 70 miles apart in small Ohio towns strung along the Lake Erie shore. They both started out as backyard inventors, launched successful electricity companies that later formed the foundation of GE, and grew old as wealthy men. But while Edison’s ingenuity has never left the public imagination, Brush’s genius is only now starting to shine.
