Tilting at Windmills: An Economic Analysis of Wind Power

David_hume_institute_thumb This paper, “Tilting At Windmills: An Economic Analysis Of Wind Power”, presents the results of a research project conducted by Professor David Simpson on behalf of The David Hume Institute. The aim of this research is to investigate the underlying economics of wind power. From being a source of energy that until recently appeared only on the fringes of the energy supply system, wind power has, over recent years, moved centre stage in the government’s energy policy. This paper asks whether the economic analysis of this source of energy really justifies such a major role and whether alternative policy options should be considered.

Tilting at windmills

The hostility aroused by the Parham project is not unusual either. Some locals complain that wind farms are noisy, ugly and (citing estate agents) that they reduce property prices. Others, like John Constable, who lives 700 metres away from the airfield, say they are just inappropriate. “I happen to like the Chrysler building,” he says, “but I don't want it near my house.”

Gamesa: Road and platform characteristics for assembly of G87/G90 wind turbine at site

G87_gamesatechspecsonroads_thumb This document prepared by Gamesa contains the specifications for building access roads to service the wind facility as well as the platform areas where each turbine will be sited. Wind developers often cite in their marketing literature that access roads will be 16-feet in width following construction. According to the document, the minimum width of an access road between wind turbines must be 10 meters (33-feet). This width does not include side slopes or additional clearing for culverts.

Impact of Wind Power Generation In Ireland on the Operation of Conventional Plant and the Economic Implications

This study by the Irish grid manager finds that the benefits of wind-generated power are small and that they decrease as more wind power is added to the system and as the system grows itself. Their model assumes that all energy produced from wind facilities would be used and did not consider output fluctuations within a time period of less than an hour. They decribe three problems that mitigate the benefits of wind power: -large amount of extra energy required to start up thermal generators that would otherwise not have been turned off -mechanical stresses of more frequent ramping of production levels up and down -increased prices of energy necessary to pay for any lower usage of thermal plants. They notice that there is very little possibility of closig any non-wind facilities, because their capacity would still be needed to respond to periods of peak demand. Wind plants add more capacity (requiring more infrastructure) with almost no reduction on non-wind capacity, the latter of which must be used more inefficiently than otherwise. As for carbon dioxide reduction-one of the primary arguments for wind-generated power- the study concludes that the cost of carbon dioxide abatement arising from using large levels of wind energy appears high relative to other alternatives.

"Wind Farms" make people sick who live up to a mile away

"Onshore wind farms are a health hazard to people living near them because of the low- frequency noise that they emit, according to new medical studies. Doctors say that the turbines - some of which are taller than Big Ben - can cause headaches and depression among residents living up to a mile away."

Impact of a large-scale offshore wind farm on meteorology: Numerical simulations with a mesoscale circulation model

Impact_of_large_scale_off_shore_windplants_on_meterology_thumb In this thesis the meteorological effects of a large-scale (9000 km2) offshore wind farm in the North Sea were simulated using the MM5 mesoscale model. The wind farm was simulated by introducing a higher roughness length (0.5 m) in the area of the wind farm. The meteorological effects were examined by comparing model runs with and without wind farm. Turbulent kinetic energy, cloud formation, precipitation and wind speed reduction were studied. Two case studies with westerly flows were performed. The first case study begins at 00 UTC July 1st 2001 and ends at 18 UTC July 3rd 2001. The second is from 00 UTC October 2nd 1999 to 18 UTC October 4th 1999.

E.ON Netz Wind Report 2004

Eon_wind_report_2004_germany_thumb E.ON Netz manages the transmission grid in Schleswig-Holstein and Lower Saxony, about a third of Germany, hosting 6,250 MW of Germany's 14,250 MW installed wind-generating capacity at the end of 2003. This report focuses on the operational challenges and costs associated with the intensive use of wind power due to wind's variability and unpredictability.

Impact of wind farms on the value of residential property and agricultural land

Windfarmsfinalreport_thumb Executive Summary -60% of the sample suggested that wind farms decrease the value of residential properties where the development is within view -67% of the sample indicated that the negative impact on property prices starts when a planning application to erect a wind farm is made -The main factors cited for the negative impact on property values are: o visual impact of wind farm after completion o fear of blight o the proximity of a property to a wind farm -Once a wind farm is completed, the negative impact on property values continues but becomes less severe after two years or so after completion ..... -The survey suggests that wind farms do not impact on residential property values in a uniform way. The circumstances of each development can be different -This report points to a need for further research to track the impact of wind farms and to examine in particular whether the nature of any adverse impact diminishes as wind farms become an increasingly familiar part of the rural scene.

Windfarms provide no useful electricity

This paper is the explanation provided by Richard S Courtney of why it is not possible for electricity from windfarms to be useful to the UK electricity grid. The explanation was presented at the 2004 Conference of "Groups Opposed to Windfarms in the UK." It includes explanation of why use of windfarms is expensive and increases pollution from electricity generation.
