The Windy City earned the nickname from blowhard politicians, not its weather conditions, but the winds that blow across the vast expanses of farmland throughout Illinois may soon help power the energy-hungry Chicago area. A Texas company will formally present a $500 million wind power project at a Tuesday hearing in Bloomington of the McLean County Zoning Board, the latest step in a process that began more than three years ago. The result -- in terms of energy produced -- would be the country's largest land-based wind farm.

The debate was put into a proper perspective by the Times-Tribune newspaper in Scranton., which wrote: “America’s future as a world power and leading economy will be determined largely by its ability to meet the increasing demand for energy, while weaning itself from foreign oil and protecting the environment.

The objective of this study is to assess the costs that could be incurred by Idaho Power in modifying its operations at the Hells Canyon Complex for “integrating” or incorporating wind energy onto its system.

The intermittent and unpredictable nature of wind generation requires a utility to have generating resources available which can increase or decrease generation on short notice in order to keep the interconnected power system balanced. While hydroelectric power plants are well suited for performing this function, there are operational impacts and costs associated with operating Idaho Power hydroelectric plants in a manner that maintains reliability and facilitates integration of energy from wind generation facilities.

The issues surrounding the integration of wind generation on interconnected power systems are numerous and complex. This study provides a first step toward understanding those issues.

David Cameron wants one; Malcolm Wicks, the energy minister, has applied for one and this week there is a full-scale Commons row about miniature wind turbines, among other forms of do-it-yourself energy generation.

Advocates of tidal energy say it is more reliable than the other marine technology, wave power. Unlike wave - and wind - farms, tides are predictable. The devices use technology similar to wind farms or hydropower, with underwater turbines being driven by the force of the tide to generate electricity.

NREL has started to analyze the wind climatology at advanced turbine hub heights based on data measured on existing tall towers in Kansas, Indiana, and Minnesota. The highest measurement level at these towers was 90–110 m. There are two significant findings from the analysis: (1) the difference in wind resource at tall tower sites in the central United States seems to be controlled by the strength of the noctural and southerly winds; and (2) the average wind shear exponent of 50-100 m at tall towers in the central United States is influenced by strong southerly winds and is significantly higher than the 0.143 often used for conservative estimates of the wind resource at turbine hub height.

Ishpeming, Michigan [RenewableEnergyAccess.com] Construction is currently under way this month on a rare wind energy project, a 200 kilowatt (kW) vertical-axis wind turbine outside a large residential complex in Michigan.

A staffer at the Helena-based Montana Environmental Information Center recently professed mystification over state energy policy. “I don't know why we're not putting as much energy behind wind development as we are to coal development,” he said. The answer is simple. Most people want the lights to come on when they flip the switch, and they don't want to go broke when they do.

If wind energy converters are located anywhere near a residential area, they must never become too noisy even in high winds. Most such power units try to go easy on their neighbors' ears, but even the most careful design cannot prevent noise from arising at times: One source is the motion of the rotor blades, another is the cogwheels that produce vibrations in the gearbox. These are relayed to the tower of the wind turbine, where they are emitted across a wide area - and what the residents hear is a humming noise. ...In a joint project with colleagues from Schirmer GmbH, ESM Energie- and Schwingungstechnik Mitsch GmbH and the Dr. Ziegler engineering office, IWU researchers have developed an active damping system for wind turbines. The project is being funded by the Deutsche Bundesstiftung Umwelt.

FAIRVIEW -- Advocates of the "small wind" generating business have landed another customer.

Newfoundland and Labrador has great potential for wind energy, but is hampered by an "isolated and relatively weak" power grid, a confidential report says. The report, obtained by CBC News, says the island's electrical grid will limit the size and potential of wind farm projects, despite a "world-class wind resource" waiting to be tapped.

... wind energy farms are not a simple panacea for the country's energy problems. Last week the Beatrice turbines were being serviced but, if they had been operational, they would not have been turning. The North Sea's winds were virtually non-existent, meaning no power would have been generated. Opponents say such variability of output is a drawback of wind energy. But O'Brien insisted: 'If we can build big turbines far away from the shore, they will cause minimum upset and disruption. This is their future and that is why the Beatrice project is so important.'

3M has announced the availability of their new Wind Tapes 8608 and 8609, which provide long-lasting protection from damage caused by sand, rain, moisture ingression, insects, and airborne particles. The new tapes are also formulated to resist the damage and weakening effects of ultraviolet rays.

Hull officials are moving ahead with plans to build four offshore wind turbines capable of producing enough electricity to power the town. An application filed last month with the state calls for erecting four power-generating windmills on a shoal known as Harding’s Ledge, roughly 1.5 miles east of Nantasket Beach. ‘‘This would be the first offshore series of wind turbines in the country,’’ Hull Town Manager Philip Lemnios said. ‘‘We had such a favorable response to our two land-based turbines, the townspeople are pursuing the offshore options.’’

The 280ft towers will stand in up to 150ft of water and will generate enough electricity to meet up to 75% of the needs of the oilfield which pumps 3500 barrels of oil ashore a day. This £35m, five-year pilot could be the first step towards establishing a 200-turbine farm on the site which could meet 20% of Scotland's energy needs.

Like most really thoughtful environmentally concerned scientists, I'd rather a tiny amount (in metric tonnes or cubic metres, after decades of use) of stored radioactive waste than the unmitigated disaster of millions of tonnes of carbon dioxide released into the atmosphere. And renewables are not realistically and politically going to fill the gap any time soon.

The Obama administration wants to rebuild the national electric grid that delivers power to everyone's toasters and televisions. One reason is that the grid can't handle all the new solar and wind power the president wants to build to create a greener energy economy. Here's the problem: Solar and wind power are intermittent. Sometimes it's sunny, sometimes it's not, and it's the same for wind. But the grid needs constant and reliable sources of power.

In May, citing a potential for reliability problems for the provincial network, the Alberta Electric System Operator (AESO) — which oversees the electricity market and transmission network in Alberta — surprised the industry by announcing that wind power generation in Alberta, currently at about 300 megawatts (MW) of capacity, would be capped indefinitely at 900 MW. However, there are proposals for about 3,000 MW of projects above and beyond the ones already lined up and paid up to meet the 900 MW mark.

A proposed wind farm project for Higgins Mountain is causing some concern for the operators of Ski Wentworth and others in the Wentworth Valley-Folly Lake area. "I want to make it clear that we are in favour of renewable energy and all of the benefits that come with it, but we do have some concerns about the proposal that will see 400-foot (120-metre) turbines being erected right across the valley from the ski hill," Ski Wentworth spokeswoman Leslie Wilson said Monday. Ottawa-based 3G Energy Corp. proposes to build 66 turbines along a seven-kilometre stretch of the Cobequid Mountains. They would be on a ridge on the opposite side of the valley from the ski hill. The project is among the largest ever proposed for Nova Scotia.
