Major step on wind energy

Xcel says wind power will mostly supply intermittent and peak power - energy demands that fluctuate day to day or even hour to hour. Unfortunately, that means it still must rely on coal, the most polluting fossil fuel, supplemented by natural gas, the most expensive fossil fuel, for its base load (the kind of electricity that's always on).

The English come to aid of Agincourt six centuries after victory

The village’s ambition to become a tourist centre was given a boost last month when the French state electricity generator, Eléctricité de France (EDF), withdrew a planning application to place four 459ft (140m) wind turbines half a mile from the battlefield. The plan had been fought by campaigners on both sides of the Channel, including the actor, Robert Hardy, who said that it would desecrate the battlefield.

Windfarms: why are we being targeted?

"Because this is rather new technology, most of the information is coming from the developers themselves and they are not going to raise matters that might be detrimental to the industry.... They are trying to rush these developments through for at the moment the system is very attractive with its tax shelters and carbon credit availability. But we need to slow this all down and look long term at the issues."

Enormous wind towers a poor power choice

This battle has been fought for decades, first with the billboard campaign, again with the "ridgeline" highway campaign, and now with enormous industrial turbines. In our hearts we believe the Legislature and the governor will protect our state's beauty and our heritage as our forefathers, legislators and governors before us.

Wind Power - 'Variable' or 'Intermittent'? - A Problem Whatever the Word

A Research Into the Achilles' Heel of the Wind Industry. With a wealth of examples and references, Dr. Etherington enlightens us on the principal weakness of windfarms: their erratic, unpredictable production of electricity. A modern economy cannot afford blackouts, so wind power production must be backed up 24h a day by conventional power, which substantially reduces the C02 savings

Grid Impacts of Wind Power Variability: Recent Assessments from a Variety of Utilities in the United States

Ewec06gridpaper_thumb In this report we discuss some recent studies that have occurred in the United States since our previous work [2, 3]. The key objectives of these studies were to quantify the physical impacts and costs of wind generation on grid operations and the associated costs. Examples of these costs are (a) committing unneeded generation, (b) allocating more load-following capability to account for wind variability, and (c) allocating more regulation capacity. These are referred to as “ancillary service” costs, and are based on the physical system and operating characteristics and procedures. This topic is covered in more detail by Zavadil et al. [4].

Annual Report: Capital Grant Scheme for Offshore Wind - Scroby Sands Wind offshore farm site

Capital_grant_scheme_for_offshore_wind_thumb The values in Table 2 are based on total availability and reflect the time that the turbines are available to operate. Hence, no allowance is made for the effects of grid outages or ‘weather days’ which could prevent access to turbines for repairs. The planned availability was exceeded for only one month and the availability across the site was below expectation especially during the autumn period. This was due almost entirely to problems with bearings in the gearbox as will be discussed in Operational Issues.

Industrial Wind Tops News From NEK In 2005

In December, Gov. Jim Douglas joined the ranks of those opposed to commercial wind farms on ridge lines, saying the huge structures are not compatible with Vermont's image. Specifically, he said he does not support the proposed UPC Vermont Wind project with 26 398-foot turbines planned for ridges in Sheffield and Sutton.
