This paper analyses aspects of environmental policy in Denmark, including, among others, policy on surface water quality, clean air and support for renewable energy, waste disposal and transport policy. Environmental policies are an important priority in Denmark, with implementation often highly decentralised, but in some cases environmental objectives have been pursued at what seems a high price, perhaps through a wish to support the development of a domestic industry or to protect existing industry from loss of competitiveness. The paper criticises some of the arguments used in favour of this high cost approach in a number of contexts, including wind power subsidies, the carbon tax and the treatment of nutrient discharges from agriculture. The paper also discusses a number of innovative and efficient policies introduced or planned, for example the new approach to promoting renewable energy (including wind power) through tradable “green certificates” and a CO2 trading scheme in electricity production. In some areas, such as policy for non-hazardous waste, apparent expansion of the role of economic instruments (through a series of differentiated taxes on disposal) seems to be dominated in practice by quantitative targets which may not provide the best outcomes.

"The main idea of wind power is to produce electricity without air pollution and without using exhaustible natural resources. However, wind power involves certain costs. These costs are among other things due to the fact that windmills stand as a foreign element in the open landscape. Some people are of the opinion that windmills in an open landscape impinge on the recreative element of the landscape. In addition to this, windmills give off noise that, depending on the wind direction and distance from the windmill, can be a nuisance for those living in the vicinity.

The purpose of this study is to evaluate how great the costs are from the visual effect and noise of the windmills. In order to make it possible to compare these costs with other costs and gains in relation to windmills, these costs are reckoned in cash terms. This has been done partly on the basis of the willingness to pay for getting rid of the windmills of people living in the vicinity (the interview method or contingent valuation), and partly using a survey of house prices in the vicinity of the windmills (the house price method or hedonic pricing) as a starting point."

This addresses the most important challenges confronting Eltra, the Transmission System Operator in Western Denmark.

Wind turbines convert the kinetic energy in moving air into rotational energy, which in turn is converted to electricity. Since wind speeds vary from month to month and second to second, the amount of electricity wind can make varies constantly. Sometimes a wind turbine will make no power at all. This variability does affect the value of the wind power……

Editor’s Note: This ‘fact sheet’ is, on the whole, a comparatively fair report. The definitions provided for capacity factor, efficiency, reliability, dispatchability, and availability are useful. Its discussion of back-up generation, marginal emissions and Germany & Denmark, however, is disingenuous as is, to a lesser degree, its discussion of capacity factor and availability. IWA's comments (updated October '06) on these issues follow selected extracts from the 'fact sheet' below.
