American Wind Energy Grows 28% And Installs 45,100 Turbines

April 16th, 2013 by  

I know we’re not supposed to choose a favourite — we should love them all equally — but I have always loved wind energy more than the others. It has a majesty and simplicity to it that I find really attractive. So I really enjoy reporting on wind energy milestones.

Wind energy grows 28% in a year, delivering more economic benefits to America than everSuch as the latest report from the American Wind Energy Association (AWEA), entitled US Wind Industry Annual Market Report for 2012, which reported that wind energy in the United States had grown 28% since 2011, setting a new installation record of 6,600 wind turbines erected during 2012, leaving the country with a total of 45,100 wind turbines, enough to power 15.2 million homes in a country with nearly 320 million people.

Not bad! It’s the best year yet for the US wind energy industry, topping all energy sources with 42% of all new US electric generating capacity.

“We had an incredibly productive year in 2012,” said Rob Gramlich, Interim CEO of the American Wind Energy Association (AWEA). “It really showed what this industry can do and the impact we can have with a continued national commitment to renewable energy. We’re doing what Americans overwhelmingly say they want: making more clean, renewable energy, and creating good jobs in U.S. factories.”

Q2 Saw the Markings on the Wall

Back in August of last year, Denise Bode, CEO of the American Wind Energy Association, spoke at the National Clean Energy Summit in Los Vegas, Nevada, revealing that 1,400 wind turbines had already been installed across the country.

At the time, that meant the US had blown through 50 GW of wind powered electric generating capacity, a figure that the AWEA explained:

  • Represents the generating power of 44 coal-fired power plants, or 11 nuclear power plants
  • Avoids emitting as much carbon dioxide as taking 14 million cars off the road
  • Conserves 30 billion gallons of water a year compared to thermal electric generation, since wind energy uses virtually no water

Some of the key projects installed during the second quarter of 2012 included:

  • Pattern Energy’s Spring Valley wind farm, 30 miles east of Ely, Nevada (151.8 MW)
  • Enel Green Power North America’s Rocky Ridge wind farm in Oklahoma (148.8 MW)
  • enXco’s Pacific Wind project in Kern County, California (140 MW)
  • Utah Associated Municipal Power’s Horse Butte project in Idaho (57.6 MW)
  • First Wind’s Kaheawa Wind II wind farm in Hawaii (21 MW)

According to the US Federal Energy Regulatory Commission (FERC) Office of Energy’s Energy Infrastructure Update for December 2012 report released earlier this year, a total of 164 wind projects were brought online during 2012, with a total generating capacity of 10,689 MW.

That final figure was close to wholly half of the year’s total installed generating capacity for all forms of generation. It’s nearest rival was natural gas, with 8746 MW brought online that year.

The same report showed that wind energy made up nearly 5% of the total percentage of US electric generating capacity, sixth on the list behind natural gas, coal, nuclear, and water.

Wind Energy Boosting US Economy

Not only was the massive boost in wind energy installations last year a boon for the renewable energy industry, but it also gave a noticeable bump to the US economy. $25 billion in private investment was put towards wind farms, tens of millions of dollars paid to landowners and local communities in lease payments and property taxes for the installation of wind farms, and billions more have been projected as savings for electricity consumers.

The input to the US economy was so significant that economists believe it was a major reason behind the government revising its estimate of fourth-quarter economic growth — from 0.1% to 0.4%.

The push wasn’t included in the Commerce Department’s first two estimates of fourth-quarter gross domestic product because the surge was first documented after the initial GDP estimates were released, said IHS Global Insight chief US economist Nigel Gault.

According to Tim Mullaney, USA Today’s economics correspondent, “the growth was due partly to scrabling by developers to get projects completed before a tax credit expired at the end of the year.”

“Wind-power growth is likely to resume later this year,” Mullaney notes, “because Congress and President Obama extended the credit for only one year as part of the tax law approved in January.”

Notably, however, this year’s extension was a little bit different from previous extensions. Previously, wind projects had to be completed by the expiration date. Now, they simply have to be started by the expiration date (which is currently December 31, 2013).

The wind industry is also providing local jobs. The AWEA report released last Thursday on a webinar for association members and reporters notes that over 550 factories across the US are providing parts and services for the wind energy industry, which totalled an impressive 80,000 American jobs in 2012.

Those jobs were given a vital release on life when Congress extended the production and investment tax credits for the wind energy industry for another year.

Wind Helping Drought Victims

The report also noted that wind power “also helped the disaster-level drought affecting half of the US counties by saving over 35 billion gallons of fresh water”.


Many electricity generating installations require copious amounts of water to operate effectively — whether as cooling or as a generating tool. Moving to wind energy generation helped save 120 gallons of water for the year for every American.

And it avoided 4% of carbon dioxide emissions in the power sector for the year, as well.

Wind Power Purchasing Increases As Well

Stepping sideways for a moment from the fantastic growth of the wind energy industry itself, utilities and institutions buying wind power also continued increasing during 2012.

According to the report, 74 electric utilities bought wind power last year, along with at least 18 major industrial consumers and 11 schools and universities. Such decisions not only allow for diversification of energy portfolios, but will continue to present energy savings for years to come.

AWEA note that at least seven utilities have issued new requests for proposals to purchase over 1,000 MW of wind power so far this year, since the production tax credit for renewable energy was extended.

“AWEA applauds these utilities for maximizing the PTC opportunity to continue bringing low-cost, fixed price wind power to their customers,” said Rob Gramlich.

“From Xcel Energy in Minnesota to OG&E in Arkansas, electric consumers are racking up the savings as a result. The wind energy industry looks forward to our continued partnerships with utilities across the country to lock in the economic development, rate stabilizing and environmental benefits of more wind power.”

Among the utilities hoping to purchase more wind power are:

  • Xcel Energy — billed as “the number one wind energy provider in the nation,” Xcel is looking at adding more wind generation in Minnesota and Colorado. “Although Xcel Energy is well ahead of meeting our state’s renewable energy requirements, we are open to adding cost-effective wind projects that could provide long-term value to our customers,” said Judy Poferl, president and CEO, of Xcel Energy’s Northern States Power Company-Minnesota. “The extension of the federal renewable electricity Production Tax Credit may make cost-effective projects available to serve our customers.”
  • Crossroads Wind Farm Image Credit: OG&E

    Oklahoma Gas & Electric — who noted in a filing in Arkansas that “from  September 2011 through June 2012, fuel costs to Arkansas customers were approximately $1.2 million lower because of the incorporation of Crossroads [wind farm] into OG&E’s generation fleet. OG&E estimates that fuel savings to Arkansas customers from September 2011 through December of 2012 will be in the range of $2.2 million. Total Company production cost savings for the first five years of operation are estimated to be $268 million. Over the expected twenty-five-year life of the asset production cost, the savings are estimated to be $2.3 billion.”

Records Aplenty

The AWEA report released this week also highlighted several grid operators reporting new records for wind generation.

New marks have been set by ERCOT (Electric Reliability Council of Texas), SPP (Southwest Power Pool), MISO (Midwest Independent System Operator), BPA (Bonneville Power Administration), and CA-ISO (California Independent System Operator).

While Xcel Energy’s Colorado system has obtained more than 50 percent of its electricity from wind on multiple occasions.

Here at CleanTechnica, we too have covered several stories of record-breaking wind generation:

A Renewable Future

One does not have to think too hard to imagine how appealing reports like this are to politicians looking for ways by which to sell the benefits of the wind industry. While the most recent extension of the PTC is set to expire at the end of 2013, the growth in the industry and the trickle-down effects of such a healthy industry will be a continually growing incentive to continue the tax credit past the end of this year and beyond.

    The new book Reinventing Fire by Amory B Lovins of the Rocky Mountain Institute says on page 189: “Onshore wind alone, in suitably windy sites on available land, could generate 9.5 times as much electricity as the US used in 2010.”

    However, the paper “Are global wind power resource estimates overstated?” by Amanda S Adams and
    David W Keith in Environ. Res. Letters, 8 (2013) ( concludes that because wind turbines have a substantial effect on the efficiency of their neighbors, maximum efficiency is likely closer to 1 W/m^2 than to 2-10 W/m^2 generally claimed in the field.

    Assuming we produce just the average power consumption of 465 GW, not the peak power, at 1 W/m^2 this is 4.65×10^11 m^2 which is 1.8×10^5
    mi^2. This is for installed capacity, so if we assume a generous capacity factor of 40%, the actual needed land area is 4.5×10^5 mi^2. The state of Texas is 2.7×10^5 mi^2 and Alaska is 6.6×10^5 mi^2. How is it possible that the potential for onshore wind power generation could be 9.5 times the amount used nationally?

      Wouldn’t you think that after over 30 years of building wind farms the engineers who design and test things would have noticed that they were getting less power than they expected?

      • TCFlood


        Let’s not do one-liner polemics. I really want to understand this thing.

        With capacity factors of 20-35% it’s hard to know how to apportion
        efficiencies. For example Philip Anschutz’s Power Company of Wyoming website ( describes a 500 sq mi ranch which is to “generate approximately 2,500 megawatts of … electricity.” It is always hard to
        know from such pieces whether they are talking about installed capacity or real production. Since they mention serving about 1 million households, (about 1.3 GW) I assume the 2.5 GW is installed. This area in Wyoming is said to have class 6 and 7 winds, so let’s assume a capacity factor of 50%. Thus average production would be 1.25 GW. This is very close to 1 watt per square meter.
        Since this is among the best wind regions in North America, other areas are unlikely to do better. The only unknown in all of this is the amount of the ranch that is planned to actually be devoted to the wind farm, but ‘most of it’ is probably not a bad assumption.

        I have not yet done a rigorous search for data from existing wind farms, but do you know of any where the real production is greater than 1 Wm^-2?

        • Bob_Wallace

          Why don’t you contact RMI and see what they have to say?

          Personally, I’m not interested. Even if Keith is correct we don’t need 9.5x as much electricity as we now use. We won’t even use onshore for half our electricity. I’d guess that wind, in total, will end up around 50% and 50% of that will be offshore. Most of our population lives close to an ocean, making transmission costs less. And offshore wind blows more hours than onshore, especially during times of higher demand.

          I would suggest you not become too enamored of Keith’s math until someone knowledgeable in the field has checked it out. I waded through another of his papers in which he was making claims about how turbines would change wind patterns and found that he was using an absurdly large number of turbines in his assumptions.

          I’ve never see a wind farm/turbine described in terms of output capacity. Always by nameplate capacity.

          • TCFlood


            I’m sorry to see such a dismissive and facile response where
            you clearly have misread or not read much of what I have written. When someone writes a book that is being read by the powers that be, it is a serious problem when they make resources and solutions seem much more plentiful and easy than they are.

            I’ll seek serious conversation elsewhere.

          • Bob_Wallace

            That’s exactly what I suggested, TC.

            Contact TMI/Lovins. Contact Mark Jacobson at Stanford. Go to the library and see if anyone has addressed Keith’s paper. Check to see if the journal in which he published it has “standing” or if it’s a “pay for publication” journal.

            My experience digging into one of Keith’s papers was that I came away with the impression, correct or not, that he was trying to build an anti-wind case and pushing the boundaries of reasonableness. Sort of like that Murphy guy at UCSC (what a shame he’s there) who sets up renewable strawmen in an attempt, I guess, to support nuclear energy.

            Again, if Lovins made an error it is not an error that changes anything. We’ve got hundreds of thousands of wind turbines up and running. We know how much electricity each produces and how much each costs. That allows us to determine the economics of wind, the the economics are great.

            We can measure the amount wind resource land we’ve used to date and, clearly, there’s a lot left. Plus the amount is increasing with newer wind turbine designs that are very productive in lower wind speed areas.

          • TCFlood

            Do you know if the cost of land is ever figured into the capital cost of wind farms or solar farms for that matter? Surely it must be an important factor.

          • Bob_Wallace

            Land costs wouldn’t be part of capex if the land is leased, which I think is the standard case. Most wind farms lease from farmers, ranchers or the federal government. Land lease costs would be part of operating costs.
            Land and transmission costs are not included in LCOE (levelized cost of electricity) numbers, even if the land is purchased. LCOE is calculated based on capex, finex, capacity and operating costs. (Heat factor and fuel costs are included for coal, NG, nuclear.)

            The selling price, the PPA (power purchase agreement) amount, will cover all the LCOE components, real estate costs, taxes, transmission and owner profits. It will be lowered by whatever subsidies are received. It’s a “delivered to the utility’s door” price.

            “The prices offered by wind projects to utility purchasers averaged $40/MWh for projects negotiating contracts 2011 and 2012, spurring demand for wind energy.”

            $40/MWh means 4c/kWh.

            For back of the envelop calculations a rough estimate of the value of wind subsidies could be had by dividing the 2.3c/kWh PTC that wind receives in half. The subsidy is given only for the first ten years of production and PPAs generally run 20 years, so 2.3c/2 = 1.15c/kWh. There’s also an accelerated depreciation schedule that wind farms can use for their capex, so that makes the subsidy a bit higher. I doubt 1.5c/kWh total would be far off base.
