This Unique Combo Of Wind And Hydro Power Could Revolutionize Renewable Energy

Tobey Grumet
October 16, 2016
Wind is a clean, cheap source of renewable energy, but it’s also fickle. You can never be sure whether the wind will blow. But engineers in Europe have now found a way to crack this shortcoming by combining it with hydropower. The big idea here is that the wind will generate electricity when it’s, well, windy, and the water will act as a giant battery that will discharge and modulate output when it stops blowing.

How GE Is Helping Build America’s 1st Offshore Wind Farm

Timothy Brown
March 18, 2016
New wind farms added more than a quarter of total new power generation capacity in the United States between 2010 and 2014, reaching 75,000 megawatts at the end of last year. No other country with the exception of China has more. But the race is on.

Cloudy With A Chance Of Electrons: This Scientist Can Forecast Renewable Electricity

Todd Alhart
February 29, 2016
A group of physicists that included a Nobel laureate and Kurt Vonnegut Jr.’s brother spent the 1940s working in GE labs to figure out how to control the weather. After a promising start – they created snowfall over Schenectady, N.Y. – the project eventually fizzled.

This Data Will Blow You Away: Renewables By Far The Largest New Power Source In The U.S.

Tomas Kellner
February 10, 2016
New solar and wind energy farms added a whopping 68 percent of new power generation capacity in the United States last year, according to a report from Bloomberg New Energy Finance. When combined with hydropower, renewables now make up a fifth of America’s electricity generation capacity, more than double what it was in 2008.

A Mighty Wind: Taking U.S. Power Generation by Storm

March 19, 2014

Wind farms have delivered 30 percent of all new American power generating capacity for the last five years. Wind also supplied more than 4 percent of all U.S. electricity for the first time in 2013, according to new data published by the American Wind Energy Association (AWEA). States like Iowa and South Dakota now get more than a quarter of their power from wind.

Friends in High Places: “Space Frame” Wind Tower Takes Renewables to Tough Locations

March 10, 2014
Engineers at GE’s wind power unit developed a new 450-foot tall “space frame” tower that could allow wind farm operators to build turbines in places that were previously inaccessible.
Instead of traditional steel tube towers, the new design is using metal latticework wrapped in a fiberglass coat. The lattice girders can be loaded inside shipping containers and onto ordinary trucks, and bolted together at the final destination. This makes logistics and transportation easier (see time-lapse video).
