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

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. “The power sector continued to de-carbonize and add near-record amounts of clean energy as policy activity at the global, national and state levels set the country on track for further emissions abatement,” the study found.
This is good news for the environment and consumers but also for companies like GE and their shareholders and customers. GE greatly expanded its renewables portfolio with hydropower, offshore wind systems and power distribution technologies when it acquired Alstom’s energy and grid business last year.

Americans will get their first taste of the combination later this year, when Deepwater Wind turns on the country’s first offshore wind farm in the Atlantic Ocean near Block Island, Rhode Island. But the United States is just one market for the technologies. Take a look at a some of the recent projects.

"With a rotor diameter spanning one and a half football fields (150 meters), the turbine can generate 6 megawatts.

We completed installation of the five jacket foundations in November," says Deepwater Wind's Stacy Tingley. "Our focus this winter and spring now turns to turbine assembly and submarine cable installation work." Image credit: Deepwater Wind

Shields2 The world’s first wind turbine  produced just 12 kilowatts, enough to supply three modern American homes. Inventor Charles Brush built it behind his mansion, in the middle of a 5-acre backyard running along Cleveland’s fashionable Euclid Avenue. Brush's business later became part of GE.

EcoROTR_1 GE is testing its latest wind turbine design, the Ecorotr, in the Mojave Desert in California. The shield attached to the nose of the turbine is designed to push wind on the blades and make the turbine more efficient. Image credit: GE Reports

The dam supplies Brazil with a quarter of its power and Paraguay with 90 percent of its electricity. Image credit: GE Power

One of them can generate as much as 800 megawatts. The turbine, which is immersed in water, spins the generator, which is the silver wheel near the top. Image credit: GE Power

SICW copy GE engineers also recently used silicon carbide chips like the one above to build one of the most efficient utility-scale inverters in the world and improve its output by 50 percent. The inverter can process power from solar installations generating 4 megawatts, instead of the typical 1-megawatt machine. Image credit: GE Global Research
