The face of Shelburne Farms changed this week when students from Vermont Technical College installed a 100-foot wind anemometer that will help determine whether the farm is a good candidate for an energy-producing wind turbine.
Researchers seeking to make the ocean's salty brine drinkable using wind power will spend the next year using the town of Hull as a case study to help other water-needy, windswept coastal areas filter freshwater from the sea. With one wind turbine already spinning, another to be installed in January, and a third offshore turbine being considered, Hull is an ideal laboratory for modeling a desalination plant that runs off a combination of renewable energy and the electric grid, according to James Manwell, director of the Renewable Energy Research Laboratory at the University of Massachusetts at Amherst.
If the wind isn't blowing at peak times, the argument goes, then the wind turbines are not contributing to the power in the grid. However, if wind farms could store all the power they generate at off-peak times, during the night for example, and then control the way and time it is released, it would not only enhance the revenue streams they could receive, but also remove the intermittency claims. Now, a Canadian energy management firm claims to be able to do just that. EPOD International has secured two pilot projects with wind power developers in Canada and the US to test their proprietary energy storage system, the EMT.
Planning Commission Chairman Brian Keefe had his hands full keeping the overflow audience from drifting away from the siting issue. Many wanted to discuss questions of aesthetics or the merits of wind power. Keefe explained that there would be at least two or three meetings to discuss those other issues.
TALLINN - Wind power has fallen out of Estonia’s favor in recent months, with the Economy Ministry deciding to limit support to wind-power producers and Parliament adopting amendments to the energy law that will give preference to other forms of renewable energy. Einari Kisel, head of the Ministry of Economy and Communications’ energy department, puts it bluntly: “We do not want to have too many wind mills,” he says. “The price of wind energy is expensive. The unstable production causes additional costs to other producers.”
The new turbines are more efficient and less costly than propeller-driven machines and earlier versions of TMA's own mills, officials say.
Wind power is an idea that is appealing to the imagination. It sounds like a "free" source of energy that would be non-polluting and stable in cost. I am an optimist, and I love technology. If I thought for one moment that windmills would be a source of low cost energy, I would be building them. The reality is quite the contrary--wind power is wasteful of human and natural resources.
A turn for the better Wind turbines are ugly and no one wants to live near one. Right? Wrong. Steve Rose on the new architects of spin
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.
"These projects are very expensive and wouldn't happen without tax subsidies," he [Glenn Schleede] said. "Ordinary taxpayers are getting taken to the cleaners on this."
Local power generation could be achieved by installing tidal turbines in Auckland's regional harbours. Two harbours are superbly suited for this purpose, and tidal-current power generation is cost-effective and environmentally friendly.
The £1million wind turbine next to Whitemoor Prison is to be switched off at certain times of the year because 'shadow flicker' is upsetting inmates.
Deep in the Allegheny Mountains of West Virginia sits a giant coal-fired power plant aptly named Mount Storm - a 1,600-megawatt goliath that just a few years ago ranked second in the nation in toxic mercury emissions.
With California's energy crisis in the headlines, advocates of wind power are hoping it will mean a major boost for this source of clean, alternative energy. But they face a previously underappreciated problem: bugs.
