Power Hungry (18 page)

As Hugh Sharman, a British-born energy analyst who lives in Denmark, put it, the Danes are providing an electricity subsidy to their neighbors. And they are doing so because Denmark cannot use all of the wind-generated electricity it produces. The intermittency of the wind resources in western Denmark—located far from the main population center in Copenhagen—means that the country must rely on its existing coal-fired power plants. When excess electricity comes onstream from the country's wind turbines, the Danes ship it abroad, particularly to Sweden and Norway, because those countries have large amounts of hydropower resources that Denmark then uses to balance its own electric grid.

Put another way, Denmark's wind turbines often produce surplus electricity that the country cannot use; thus, that power must be exported. Its neighbors' hydropower resources “are effectively batteries for Danish wind energy,” said Sharman.

(Norway utilizes more hydropower as a percentage of primary energy than any other country, getting some 68 percent of its total energy needs from water. Sweden ranks seventh in hydropower utilization, getting nearly 30 percent of its primary energy needs from water. For more on this, see Appendix D.)
²¹

In September 2009, the Danish Center for Political Studies, known as CEPOS, a Copenhagen-based think tank, came to the same conclusion as Sharman, declaring that this “exported wind power, paid for by Danish householders, brings material benefits in the form of cheap electricity and delayed investment in new generation equipment for consumers in Sweden and Norway but nothing for Danish consumers.”
²²

None of this is aimed at belittling Denmark. The country has had remarkable success at keeping energy demand down. It is one of the few countries where energy demand growth is essentially flat. In 2007, the country's total primary energy use, about 363,000 barrels of oil equivalent per day, was roughly the same as it was in 1981.
²³
Denmark's ability to keep energy consumption growth flat over such a long period is anomalous.
But let's be clear: That near-zero growth in energy consumption has been achieved in part by imposing exorbitant energy taxes and by maintaining near-zero growth in population.

Thanks to their government's exorbitant tax rates, the Danes pay some of the highest electricity rates in the world. In 2006, the Energy Information Administration looked at residential electricity rates in sixty-five countries and found that Denmark's rates were the highest by far, amounting to some $0.32 per kilowatt-hour. That was about 25 percent higher than the electricity costs in the Netherlands, which had the nexthighest rates in the survey at $0.25 per kilowatt-hour. And that's not a new phenomenon. From 1999 through 2006, Denmark had either the highest—or the next-highest—electricity rates of the countries surveyed by the EIA. (In 1999 and 2000, Japan's electricity rates were slightly higher than those in Denmark.)
²⁴
Furthermore, Denmark's electricity rates are the highest in Europe—and no other country comes close.
²⁵

In 2008, electricity rates were even higher, with Danish residential customers paying $0.38 per kilowatt-hour—or nearly four times as much as U.S. residential customers, who were paying about $0.10 per kilowatt-hour.
²⁶
And the Danes were paying more than twice as much as their counterparts in nuclear-heavy France, where residential electricity costs were $0.17 per kilowatt-hour.
²⁷

While Danish homeowners are getting spanked by expensive electricity, Danish motorists are getting absolutely mugged at the service station. In late 2008, Danish drivers were paying an average of $1.54 per liter for gasoline (the equivalent of $5.83 per gallon), while drivers in the United Kingdom were paying $1.44 per liter ($5.45 per gallon) and U.S. motorists were paying $0.56 per liter ($2.12 per gallon). According to German Technical Cooperation (GTZ), an agency of the German government, only a handful of countries have more expensive fuel than Denmark, a list that includes Italy, Norway, Turkey, and Germany.
²⁸

Although Friedman, Lovins, and Green want to hold up Denmark as a model to be emulated, the brutal facts show that Denmark is even more reliant on oil—as a percentage of primary energy—than the United States is. In fact, the Danes are among the most oil-reliant people on Earth. In 2007, Denmark got about 51 percent of its primary energy from oil. That's far higher than the percentage in the United States (40 percent) and
significantly higher than the world average of 35.6 percent. As stated above, Denmark is more coal dependent than the United States, getting about 26 percent of its primary energy from coal while America gets about 24 percent of its primary energy from the carbon-heavy fuel.

But given the global worries about climate change and carbon dioxide, the key issue for Denmark is this: Has wind power made a difference in its carbon dioxide emissions? The answer, based on the country's own data, appears to be no. Although Denmark has more than doubled its wind power production over the past decade or so, it has not seen major reductions in its carbon dioxide emissions or its coal consumption.

In 2008, the European Environment Agency released a report that analyzed the progress (or lack thereof) that European countries are making toward their carbon emission reduction targets under the Kyoto Protocol. The report found that Denmark was falling short of its 2010 reduction targets by 18.8 percent.
³⁰
It also found that between 1990 and 2006, Denmark's overall greenhouse gas emissions increased by 2.1 percent.
³¹
Although that's a much better emissions profile than that of Spain, where emissions jumped by 50.6 percent over that same time period, it's obvious that Denmark's emissions have not declined despite its big increase in wind power production. Between 1990 and 2006, according to the European Environment Agency, Denmark's annual per-capita emissions of greenhouse gases stayed essentially the same—at about 13 tons of carbon dioxide.
³²

If Denmark's huge wind-power sector were reducing carbon dioxide emissions, you'd expect the Danes to be bragging about it, right? Well, guess what? They're not.

In early 2009, Energinet.dk, the operator of Denmark's electricity and natural gas grids, published a handsome brochure available on its website entitled, “Wind Power to Combat Climate Change: How to Integrate Wind Energy into the Power System.”
³³
But the 56-page report does not contain any evidence that wind power has done anything to cut carbon dioxide emissions.
³⁴
The only claims it makes are about the role that wind
might
play in cutting emissions in the future. The report quotes Henriette Hindrichsen, a senior consultant at
Energinet.dk
, who declared that given enough wind power, Denmark “could” cut its use of hydrocarbons. “We could save fossil fuels,” she helpfully explained, “and thus reduce carbon dioxide emissions by moving some of our consumption away from peak-load periods to times of considerable wind and low consumption.”
³⁵

It's critical to note that
Energinet.dk
does not say that wind
will
cut carbon emissions, only that it
could
. The report—which claims to be a “carbon dioxide–neutral product” because the gases produced during its production were “neutralized by buying carbon dioxide quotas from Climate Friendly via the WWF”—also discusses the potential for using wind power to charge electric vehicles in Denmark. It does so by breezily noting that “Danes have never really taken a fancy to electric cars even though they are tax-free. For this reason, only about 300 electric cars buzz along the Danish roads.”
³⁶

Despite all this,
Energinet.dk
is certain that someday soon—real soon—Danes will be driving electric cars, and when they do so, those cars will “absorb surplus wind power, significantly reduce transport sector carbon dioxide emissions and help to balance the power system if the
batteries are charged or drained as required.”
³⁷
But of course, that will only happen when, or if, Danes “take a fancy” to electric cars. In late 2009, the Danish government announced that it would offer huge incentives—a $40,000 tax break on each electric car, as well as free parking in downtown Copenhagen—to customers who bought all-electric vehicles. The government also announced plans to set up thousands of charging stations, as part of a deal with Better Place, a California-based company that is promoting electric vehicles.
³⁸

Though the Danish government is pushing electric cars,
Energinet.dk
is not making any claims about the ability of wind power to cut carbon dioxide emissions. The grid operator's annual reports from 2006 and 2007 contain no references to reduced carbon dioxide output due to wind.
³⁹
More important is this:
Energinet.dk
's 2008 environmental report contains a graph showing that in 2007, carbon dioxide levels from electricity generation totaled about 23 million tons, about the same amount as in 1990, before the country began its frenzied construction of wind turbines.
⁴⁰
And the glossy 44-page document forecasts no decreases in carbon dioxide emissions through 2017.
⁴¹
In other words, even though Denmark uses hydropower—a zero-carbon-dioxide source of backup power for its wind turbines—it still hasn't seen a reduction in its carbon dioxide emissions from its electric generation sector.

Nor has Denmark seen a significant decrease in its total carbon dioxide emissions from all sources of electricity generation, transportation, and the like over the past two decades. According to the IEA, in 1990, Denmark emitted a total of 50.7 million tons of carbon dioxide. In 2007, the country's emissions totaled 50.6 million tons, a reduction of just 0.1 percent.
⁴²

Denmark saw a significant increase in its overall electricity use during that same time period, with consumption rising from 28.8 billion kilowatt-hours in 1990 to about 35 billion kilowatt-hours in 2007.
⁴³
That's an increase of 21.5 percent. Thus, Denmark has, it appears, been able to hold its carbon dioxide emissions flat while increasing electricity production by about one-fifth. That's a laudable achievement. But part of the ability to control carbon dioxide emissions comes from demographics. In 2008, Denmark had a population of 5.5 million, and its population growth rate was just slightly above zero.
⁴⁴
In fact, Denmark has one of
the slowest-growing populations in Europe. Between 1998 and 2008, the population grew by just 200,000 people.
⁴⁵
During that same time period, the U.S. population jumped by about 33 million people.

Given that population data, several key interrelated questions emerge: Has Denmark been able to keep its carbon dioxide emissions flat because of its slow-growing population? Is the emissions rate holding steady because of the exorbitant electricity and motor fuel taxes? Or is the increased use of domestic wind production and imported hydropower holding the emissions rate down?
