FT.com / Home UK / UK - Solar power sees light at end of tunnel

Tue, 16 Sep 2008 19:17:14 -0000

Wind power has long been the big beast of the renewable energy jungle. The technology to generate electricity from wind has been established for more than two decades, and in the past five years has been refined and expanded towards much larger and more powerful turbines including ones that can be used at sea, and towards very small turbines that can be fixed to office buildings or houses.

Wind Power in New York: All Hot Air? | celsias°

Fri, 12 Sep 2008 19:31:23 -0000

Highlights and Sticky Notes:

"It really is renewable energy gone wrong," said the Franklin County district attorney, Derek P. Champagne, who began a criminal inquiry into the Burke Town Board last spring and was quickly inundated with complaints from all over the state about the wind companies. "It's a modern-day gold rush," he said.

Air Storage Is Explored for Energy (NYTimes.com)

Wed, 27 Aug 2008 08:05:37 -0000

[A] New Jersey company plans to announce on Tuesday [8/27/08] that it is working on a solution to this perennial problem with wind power: using wind turbines to produce compressed air that can be stored underground or in tanks and released later to power generators during peak hours.

The Energy Challenge - Wind Energy Bumps Into Power Grid’s Limits - Series - NYTimes.com

Wed, 27 Aug 2008 07:57:12 -0000

When the builders of the Maple Ridge Wind farm spent $320 million to put nearly 200 wind turbines in upstate New York, the idea was to get paid for producing electricity. But at times, regional electric lines have been so congested that Maple Ridge has been forced to shut down even with a brisk wind blowing.

That is a symptom of a broad national problem. Expansive dreams about renewable energy, like Al Gore’s hope of replacing all fossil fuels in a decade, are bumping up against the reality of a power grid that cannot handle the new demands.

Small-scale wind energy | Carbon Trust

Sun, 24 Aug 2008 06:32:54 -0000

Highlights and Sticky Notes:

Small-scale wind energy (wind turbines <50kW rated capacity) is receiving increasing interest as one of a number of microgeneration technologies with potential to reduce carbon emissions. Recent years have seen new products being made available on the UK market, which a survey by the British Wind Energy Association (BWEA) suggests is growing quickly.

However, the overall potential of small-scale wind energy to reduce carbon emissions, and the conditions under which maximum carbon reductions can be made, have not been entirely clear.

Yes, but I heard that the energy generation of wind turbines was proportional to the square of the diameter. Therefore if you just half the diameter of a large one you quarter the energy captured. posted by radoxme

This Land - In the Hills of Nebraska, Change Is on the Horizon - NYTimes.com

Thu, 07 Aug 2008 12:42:39 -0000

Driving south out of the agricultural town of Ainsworth, you can’t miss its newest crop: wind turbines, three dozen of them, with steel stalks 230 feet high and petal-like blades 131 feet long, sprouting improbably from the sand hills of north-central Nebraska, beside ruminating cattle.

Though painted gray, the turbines stand out against the evening backdrop of battleship-colored thunderclouds and bear an almost celestial whiteness when day’s light is right. Airplane pilots can spot them from far away, and rarely does a bird make their unfortunate acquaintance.

The sound of 8.5-ton blades, three to a turbine, turning and turning, only enhances their almost supernatural presence. Standing at the base of a turbine’s stalk, you hear a whistling whoosh — whuh ... whuh ... whuh — as steady summer winds come like the breath of gods to toy with pinwheel amusements.

REpower Installs 5-MW Wind Energy Turbine at Thornton Bank

Wed, 30 Jul 2008 18:27:23 -0000

Highlights and Sticky Notes:

REpower Systems AG has successfully installed the first of six wind energy turbines for the Belgian offshore wind farm Thornton Bank. The project, located about 30 kilometers off the coast, is the first Belgian offshore wind farm. For the first of three construction phases, REpower is providing six 5-megawatt (MW) offshore turbines, adding up to a total capacity of 30 MW.

Belgium finally joins the league of nations with offshore wind power. posted by keulenae
