IER's Danish Wind Study: Response to Critics

[Editor note: The post is a slightly revised version of what was posted at the Institute for Energy Research website on September 17. The primary author was Daniel R. Simmons, director of state energy affairs. Next week, Michael Giberson will evaluate IER's defense of the Danish study at MasterResource in light of his own first impressions.]

Energy is critical for our economy and our future, and the real issues deserve to be debated. That is why we appreciated the initial response on the American Wind Energy Association’s website to the recent study, Wind Energy: The Case of Denmark. It appears that AWEA actually read the study and raised some questions related to energy.

The same cannot be said of other responses, such as this blog post from NRDC. But then, of course, AWEA’s Senior Vice President for Public Policy couldn’t help himself and resorted to the same innuendo and ad hominem attacks against any effort that gets the facts out about the true costs of wind energy production.

Before we discuss AWEA’s disagreements with IER and the Danish wind study, it is important to note what AWEA did not disagree with.

  • Wind is heavily subsidized;
  • Wind power is an inefficient way to reduce carbon dioxide emissions. (The Danish wind study, for example, found that it costs on average $124 per ton of carbon dioxide reduced); and
  • Subsidizing wind power is a very inefficient way to create jobs. (The Danish wind study found that, optimistically, “the subsidy per job created is 600,000-900,000 DKK per year ($90,000 – $140,000 USD). This subsidy constitutes around 175-250% of the average pay per worker in the Danish manufacturing industry.”)

The AWEA, however, disagreed, with a few other issues which we discuss below.

Wind Energy: The Case of Denmark

President Obama, the AWEA, and other supporters of wind energy point to Denmark as a model the United States should emulate. For example, as the AWEA writes in a fact sheet, “In western Denmark, wind supplies more than 25% of the electricity that is used during windy winter nights. If wind energy in the U.S. were combined with serious efforts to increase energy efficiency, we could substantially reduce our national use of fossil fuels to generate electricity.” As the Danish wind study shows, Denmark’s situation is substantially different from the situation in the United States. As a result, Denmark wind’s production is not directly replicable by the United States.

To understand Denmark’s electricity situation, we must first understand electricity production in Norway and Sweden. When electricity from wind is produced but not consumed in Denmark, the electricity is exported to Norway and Sweden. This electricity directly replaces hydropower in Norway and Sweden, allowing Norwegian and Swedish lakes and reservoirs to retain more water than release the water to produce electricity. This is only possible because of Norway and Sweden’s vast hydropower resources. According to the International Energy Agency, in 2006, over 98 percent of electricity production in Norway was produced by hydropower[1] and 43 percent Sweden’s electricity was produced by hydropower.[2]

In America, it is harder to balance the electricity wind provides to the grid. Hydropower only supplies 6 percent of the electricity in the United States.[3] In some markets, such as the Pacific Northwest, hydroelectric power is plentiful. But the fickle nature of electricity from wind means that even in the Pacific Northwest it is difficult to balance the electrical load and the Bonneville Power Administration is increasing rates for wind operators by 90 percent (down from a proposed 300 percent increase).

Furthermore it is difficult for wind to replace much of the electricity generation from coal and natural gas. Coal-fired power plants are baseload electricity plants. They are not made to cycle as the wind ebbs and flows. Natural gas-fired turbines can cycle on and off to even out wind production, but natural gas-fired turbines are less energy efficient than combined cycle generation.

Electricity from wind only supplies an average of 9.7% of the electricity Denmark consumes, the rest of Denmark’s subsidized wind production is exported, bringing no direct benefit to Danish ratepayers


Wind produces the equivalent of 19 percent of the electricity consumed in Denmark. But, on average, over half of the electricity from wind in Denmark is exported. The AWEA does not understand why the Danish wind study is critical of exporting highly subsidized electricity. The AWEA writes that “it seems especially strange for a self-described “free-market” ground like IER to be so dismissive of interstate trade.”

The Institute for Energy Research and the study’s authors support free trade. The authors of the Danish wind study are concerned that Danish ratepayers subsidize wind power with few concomitant benefits to the Danes. As the study explains on page 22:

But for the Danish householder who is paying the subsidy in order to save imported fuel and CO2 emissions, the subsidy so exported brings no direct benefit at all. The total probable value of exported subsidies between 2000 and 2008, was DKK 6.8 billion (€ 916 million) during this period.

As the paper clearly states, the problem is not the trade, the problem is the export of subsidies. Because Denmark subsidies electricity from wind, it is logical to assume that Denmark should receive the perceived benefit of those subsidies. This is especially true when Danes have exported electricity for which they paid $1.3 billion in subsidies from 2000 through 2008.

AWEA argues that the Danish Wind Study has no bearing on the situation in the United States

AWEA argues that “even if the claim made by the study were true, this example would have no bearing on the situation in the U.S.” The Danish wind situation is very relevant to the situation in the United States. AWEA has cited Denmark as a model for the United States (in this fact sheet for example, and this article on integrating utility-scale wind energy onto the grid). When President Obama and the AWEA cite Denmark as a model, it makes Denmark relevant.

The AWEA fully supports a “strong” renewable electricity mandate to require electrical utilities to get 20 percent of their electricity from renewable sources. Denmark may produce 19 percent of their electricity from wind but as explained above, that large percentage does not translate to the situation in the United States.

The AWEA seems to believe that the Danish wind study is critical of electricity exports and because the United States is only weakly tied to the Mexican and Canadian electrical grid, the Danish study is of no import. This misapprehends the point of the study. There problem is not with the export of the power. The study is concerned with exporting subsidies, the benefits of which should accrue to Danes, not the Swedes or Norwegians.

Wind power from Denmark does not reduce carbon dioxide emissions in Norway or Sweden

The AWEA claims that wind power flowing to Norway and Sweden reduces carbon dioxide emissions in Norway and Sweden. This is incorrect because only a very small portion on Norway and Sweden’s electricity is generated from coal, oil, or natural gas.

As noted above, according to the International Energy Agency, in 2006, over 98 percent of electricity production in Norway was produced by hydropower[4] and 43 percent Sweden’s electricity was produced by hydropower.[5] Another 47 percent of electricity production in Sweden came from nuclear power. Only 0.5 percent of Norway’s electricity comes from coal, oil, or natural gas in Norway and 3 percent of Sweden’s electricity. The graph below shows the electricity generation profiles of Norway and Sweden:[6]

Denmark’s geography is indeed better suited for wind generation than the United States

AWEA claims that the United States has better wind resources than Denmark. The mere fact that there are some good (or even fantastic) wind resources in the United States does not matter if those resources are off the electricity grid and far from electricity consumers because transmission lines necessary to transport the electricity are very expensive.

The whole of Denmark is 281 miles east to west and 229 miles long. The entire population of Denmark is not far from good wind resources (as this map shows). That is not true in the United States. As this map shows, the best onshore wind resources are in the Midwest from the Texas panhandle north to the Canadian border. There is not one large city in this area, making it expensive to get electricity from this wind to market.

Wind offshore is closer to major population centers in the United States, but offshore wind production is even more expensive than onshore wind electricity production. EIA estimates that by 2016, offshore wind will still be 62 more expensive that onshore wind and onshore wind will still be 49 percent more expensive than coal and 77 percent more expensive than advanced combined cycle natural gas electricity generation.[7]

IER’ has more on the levelized costs of electricity production here.

levelized costs of electricity production


Wind energy (here, there and everywhere) is very expensive and highly subsidized

For decades the promoters of wind have argued that wind’s cost competitiveness is just around the corner. For example, in 1986, a representative of AWEA testified:

The U.S. wind industry has . . .demonstrated reliability and performance levels that make them very competitive. It has come to the point that the California Energy Commission has predicted windpower will be that State’s lowest cost source of energy in the 1990s, beating out even large-scale hydro.

We are not quite there. We have hopes.[8]

Christopher Flavin of the Worldwatch Institute has been predicting competitive viability since the 1980s. In 1984 he wrote:

Tax credits have been essential to the economic viability of wind farms so far, but will not be needed within a few years.[9]

In 1985, he wrote:

Although wind farms still depend on tax credits, they are likely to be economical without this support within a few years.[10]

In 1986, he wrote:

Early evidence indicates that wind power will soon take its place as a decentralized power source that is economical in many areas…. Utility-sponsored studies show that the better windfarms can produce power at a cost of about 7¢ per kilowatt-hour, which is competitive with conventional power sources in the United States.[11]

Even after more than two decades, wind still isn’t cost-competitive and EIA predicts wind will still be 49 to 77 percent more expensive than coal and natural gas in 2016.

The wind lobby has been very effective at securing subsidies, set-asides, and favorable tax treatment

There are a number of ways wind is subsidized and assured market share including the renewable electricity production tax credit, accelerated depreciation (Modified Accelerated Cost-Recovery System), the renewable energy production incentive, renewable energy manufacturing tax credit, state-level renewable electricity mandates, and a large number of other financial incentives at the federal and state level.

It is not surprising that electricity production from wind has expanded recently. Wind turbine designs have improved, but wind remains very expensive and as this list of subsidies, tax credits, and set-asides shows, the American taxpayer is footing the bill for the wind’s expansion. Even after decades of financial support, electricity from wind still only supplies 1.3% of all electricity generated in the US.


The promoters of wind point to Denmark as an example the United States should emulate. But as the Danish wind study shows, Denmark wind’s production is not directly replicable by the United States. The Danish wind experiment also shows that generating electricity from wind is an expensive way to create jobs or reduce carbon dioxide emissions.

Which leads to a final thought: If wind power is everything that proponents say it is, then why can’t it exist in the marketplace without government subsidies, government mandates, government tax credits, guaranteed market share in the form of government enforced feed-in tariffs, and backup generation from more reliable energy sources such as hydropower or natural gas?

When it comes to the production of electricity, it might appear than the answer is Blowin’ in the Wind but as the Danish study shows, upon closer examination a better wind anthem should be It Ain’t Me Babe.

I don’t see any evidence that the energy required to manufacture windmills is accounted for. I roughly estimate that 90¢ of every dollar spent goes to energy, since an extracted resource can only be compared to other extracted resources. This means, a $5 million dollar windmill uses $4.5 million in energy to produce it. There is no reduction in carbon dioxide in that dynamic.

2 Tom Stacy { 09.19.09 at 3:54 pm }

IER has elegantly described the cost, carbon avoidance and fossil replacement problems with wind energy. With a bit more digging, a breakdown of wind energy’s entire revenue stream could be displayed, putting an exclamation point on the cost issue. This would obviate why the AWEA and other wind interests push for reducing non-delivery penalties and allowing negative bidding into grid supply auctions – forcing lower cost base load sources to opt out more frequently than they were designed to, and the entire rest of the system to operate less efficiently.

The only major issue not touched on here is the sprawl and inappropriate placement of massive numbers of gigantic, non-compact intermittent generation units in low wind, high population density areas of the US.

The effect of too much subsidy clearly has many undesirable side effects.

We appreciate that IER has taken the time to read and respond to our initial debunking of the misleading and false claims made in their report. For a follow-up debunking of the new arguments made above, please see our website:

Mr. Goggin:

It is just fine to make your points–and the comment above is polite–but why the ad hominem stuff? Your critique of IER’s comments begins with “The fossil fuel lobby continues …” and “the fossil fuel lobby front group…”.

I founded IER in 1989, and it is not a “front group” or “fossil fuel lobby.” IER is a scholarly organization that has a strong intellectual case that the energies that consumers voluntary chose are the best ones–and the modern wind industry is government-dependent from start to finish.

For the historical record, let me fill you in on a key reason why I founded IER: to have an independent voice in the energy debate while I was at Enron. And I fought Enron hard on its decision to enter into the wind business in 1997–a decision that all but saved the US wind industry (Zond was in trouble, and Kenetech was near bankruptcy).

I can name you the two Enron lobbyists that were at work to get the 1999 Texas renewable mandate–all to benefit Enron Wind Corporation. (Enron was at the forefront of what is now called the climate-industrial complex.)

I recount in some detail Enron’s lobbying campaign that sparked the Texas and thus national wind boom in different posts here: http://masterresource.org/?cat=45.

Your organization, AWEA, worked with Enron officials in an attempt to muzzle me while I was at Enron, in fact. If you scroll down here: http://www.politicalcapitalism.org/enron/060898.pdf
you will see a June 3, 1998, memo from AWEA’s communications coordinator Michelle Montague to Ken Karas, head of Enron Wind. Karas tried to get me fired–preventing me from ‘speaking truth to power,’ if you will.

Would you or any other AWEA person care to have a discussion/debate about the history and purpose of IER, the (political) history of the US wind industry, and the merits of windpower versus consumer-chosen alternatives? Let’s decide on a time and place and invite the media to attend.

The wind energy advocates are to be congratulated on their success in cowing policitians and misleading large numbers of the public into believing wind powered turbines hold the key to saving the planet despite the fact they have no record of having reduced CO2 in any substantial amounts and despite being incapable of existing absent massive subsidies at public expense. They are a wonderous example of negative efficiency.

I think wind as had about all the wind it can stand. It does make sense for a Wyoming rancher, 50 miles from a power line.
