Mighty Wind: U.S. Wind Turbine Capacity Now Equals 11 Nuclear Plants

August 30, 2012

This week, Hurricane Isaac delivered yet another lesson of wind’s wild ways. Properly employed, however, wind is a powerful aide. The American Wind Energy Association said this month that U.S. wind turbines can produce 50 gigawatts of electricity, the same amount as 11 nuclear power plants or 44 coal-fired plants. Wind energy now powers the equivalent of nearly 13 million American homes. States like South Dakota and Iowa get 20 percent of their electricity from wind. GE workers have designed and built many of the wind mills rising from fields, farms and seas in the U.S. and abroad.

Starting a decade ago, GE injected its nascent wind business with a heavy dose of engineering and manufacturing know-how, materials science, and advanced technologies from GE Global Research.

There are now 18,000 high-tech GE wind turbines installed around the world, generating 60 million megawatt-hours of renewable electricity every year, enough to power the equivalent of New York City. The wind energy unit has generated $30 billion in revenues. “The wind business might be one of the best investments we’ve made and Global Research has the technology and to keep it strong,” says Mark Vachon, GE’s vice president for ecomagination.

GE has many kinds of wind turbines in its portfolio, both on-shore and off-shore, some standing 40 stories tall. The company has spent $2 billion on wind innovation over the last decade. Last year, GE received 184 clean energy patents, the most among corporations in the United States. The wind business received the vast majority, 152 patents in total.

The benefits of wind power are obvious. Consider that just one coal plant emits roughly 3,700,000 tons of carbon dioxide annually. The offset CO2 emissions from U.S. wind is equivalent to taking 14 million gasoline-powered cars off the roads.

Switching to wind power also means saving water. Compared with thermal electric generation, wind power conserves 30 billion gallons of water a year.

By 2030, wind energy has the potential to meet up to 20 percent of energy needs in the U.S., according to the U.S. Department of Energy. GE is already helping to improve wind integration and turbine monitoring to boost efficiency and cut downtime.

Reaching the 20 percent wind energy goal, the DOE estimates, would offset CO2 emissions by 626 million tons, save over 450 billion gallons of water, and create over two million U.S. jobs.

    Would love to see GE do the same with solar.

    Great place to work and contribute to the growing energy demand.

    The story uses fuzzy math. The 60 million MW is the installed capacity if the units run 100% 365 days a year. The average capacity of a wind turbine is closer to 15%, i.e. it is only generating power 15% of the time due to wind loads, maintenance, etc. Thus the 60 million MW is really only generating about 9 million MW annually. Nuclear and fossil plants run at about 93~97% capacity factor.
    Also, nuclear plants do not “use” water. Water is used for cooling (as in fossil plants) by passing the water thru a condenser. The water is returned to the source in the same (or better) condition then when removed. All process water is recycled.

    “Can produce 50GW”…..but what is the actual? You should specify the capacity factor.

  • Charles Bagnal

    You’re correct on the capacity factor, but his is really already factored into the story, since the 50 GWe is noted as the equivalent of 11 nuclear plants, rather than 50… and it’s thousands of MWe, not millions.

  • Charles Bagnal

    Here are the latest capacity factor data for the US (average for 2010 and 2011)…
    ~
    Nuclear – 90%
    Biomass – 75%
    Geothermal – 71%
    Coal – 63%
    Gas/Oil – 46%
    Hydro – 38%
    Wind – 30%
    Solar – 21%

    So let me get this straight, even with the nice numbers, 18,000 wind mills placed around the world can power New York City. So we only need 162,000 more wind mills to cover 10 major cities. woohoo!!

    Clean coal is an oxymoron… And would you rather live a mile from a broken wind turbine, or a broken nuclear reactor?
