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).
MCHENRY - Although the mountain tops of Western Maryland are currently “turbineless,” plans for several wind farm projects are in various stages of development.U.S. Windforce, a Pennsylvania-based company, has a number of projects in the works.
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.
"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."
STAMFORD, Conn. - Giant windmills are popping up on farms, scenic mountain ridges, prairie grass and now an Indian reservation, dramatically changing the nation's landscape and spinning a debate about where they belong.
His [Dr. Charles Warren] study has little relevance to the debate on wind farms, and it is unhelpful for him to offer up what appears to be disingenuous research.
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.
"If it's difficult for me [Public Service Commissioner Susan Wefald] to figure out who's doing what (in wind development), the average person doesn't have a chance," she said.
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
Introduction and Background
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. .
Canada's smallest province is facing some hurdles as it tries to erect more wind turbines in an effort to switch to clean energy sources.
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.
CHIKMAGALUR: Wild Cat, an environmental organisation has welcomed the stay order of the court directing the Bababudangiri hills wind farm development company to stop erecting windmill poles in the hill range.
BISMARCK, N.D. -- Two utilities and a pipeline company have dropped plans to build a wind farm in southeastern North Dakota, in part because of rising wind turbine prices, officials said.
Londonderry voters approved a new town plan earlier this year that would ban development of mountain ridgelines. But the effect on the Glebe Mountain project is uncertain: The town has no vote on the project, and its fate rests solely with the PSB.
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.
