A blow for power in the North Sea

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.
A green challenge: Make renewables reliable

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.

A heavy blow for wind power - Cap on generation ’stalls the business’
October 21, 2006 by Geoffrey Scotton in Calgary Herald
October 21, 2006 by Geoffrey Scotton in Calgary Herald
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 mountain of questions; Ski hill operator, residents raise concerns about impact wind farm of Wentworth area

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.
A new twist for wind power technology

LONDON, March 21 (UPI) -- Wind turbines have long been fixed in the public imagination as giant propellers on sticks, marching across rural landscapes to the ire of local residents. But now an alternative design of turbine that rotates on a vertical axis is attracting renewed interest, as developers consider the benefits they may bring in terms of reduced noise, increased efficiency, versatility and aesthetics.
Tim and Robyn Wood don't have to sweat over the electric bills for their Oregon home.
More often than not, their utility company - Wisconsin Power & Light of Madison - pays them for electricity.
With a 24-panel solar array for electricity, a separate solar panel system for the water heater and a small wind turbine, the Woods' home is still connected to the state's grid of electric transmission lines. But for the most part, the Woods power their own lights, laundry machines, computers, television and other household appliances.
"I use power whenever it's cloudy out and there's no wind. But when the wind is blowing and the sun is shining, I make enough power that I can turn my meter backward," Tim Wood said.
As consumers, we pay the full market price for wind-generated electricity plus the value of renewable energy credits mandated by the Legislature. As federal taxpayers, we donate another two cents per kWh, and support the fast depreciation (tax savings) allowed wind installation entrepreneurs. Mars Hill’s units produce 1 percent of Maine’s electricity and 0.01 percent of New England’s. The Kibby Mountain proposal of 44 three-MW units is projected to produce about .37 billion kWh per year. The number of kilowatt-hours supplied by the wind is very small. The combined output from Mars Hill and Kibby Mountain would be about 5 percent of Maine’s or .5 percent of the total New England grid.
The real cost of wind energy, if broken out on our electric bill, would be a shock.
Each row of turbines dramatically effects the turbulence in the wind stream downwind ...Complicating the modeling is the fact that wind isn't all that predictable even without the turbines there. Wind can blow steadily or change its speed and direction constantly, and predicting the interactions of such a variable entity with turbines is beyond the grasp of even the most sophisticated computer models at presewnt.
A real-life water, wind laboratory Turbines focus of study on desalination plant

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.
April 24, 2006 issue - As projects to build "wind farms" of massive, electricity-generating wind turbines continue to multiply, so do the ranks of "not in my backyard" protesters.

Acciona to introduce concrete towers for wind turbines
August 18, 2011 by David DeWitte in The Gazette
August 18, 2011 by David DeWitte in The Gazette
Iindustry publication Recharge in May reported on the height advantage of the 120-meter all-concrete towers Acciona plans to offer. It said the higher tower height and an enormous 116-meter rotor would extend the reach of Acciona's new turbine.
Others may be concerned about health issues but he said his major concern deals with the financial impact of these energy producers, especially considering taxpayers will have to pay back the funds borrowed from China for Obama’s stimulus plan.

Activists, utilities duel over powerlines, again
November 23, 2007 by David Peterson in Star Tribune
November 23, 2007 by David Peterson in Star Tribune
It's back to the '70s for the south metro, as a new generation of major powerlines is being proposed for rural land -- and activists and farmers begin to meet. ...The companies are seeking state approval for a cluster of major lines. Two of them -- 345-kilovolt lines with towers as high as 150 feet, one stretching 230 miles west to South Dakota and the other 150 miles southward to Wisconsin -- would cross Dakota County. No specific pathway has yet been laid down, but the general outlines of the corridors -- mostly 10 to 12 miles wide -- are clear.
Points of controversy are expected to include whether the lines are needed, whether they pose health risks and how much landowners should be paid.
Darrel and Jean Gogel's Trochu acreage is a piece of calm in a hectic world--where Darrel can retreat after working days away as a truck driver, and Jean can unwind from her job as a hospital housekeeper.
That could change, the couple says, if a plan for a 54-turbine wind farm near their house goes ahead.

Ontario will overtake Alberta as the wind-power capital of Canada by the end of the year, in part because Alberta doesn’t have enough transmission lines to connect new wind turbines to its power grid.
The race to build new sources of alternative energy from the wind is running into a formidable obstacle: not enough windmills...Numerous wind-power projects from Virginia to California have been stalled due to the shortage. But for some renewable-energy companies in Europe, where wind power has been in vogue for almost two decades, the logjam is a lucrative opportunity. These firms anticipated a shortage of turbines and locked in orders with makers. They're now using their considerable buying power to gobble up smaller utilities in the U.S. that couldn't otherwise get their hands on turbines.
America has an addiction. Denmark's alternative energy producers may have the cure

The excitement amongst Danish alternative energy producers was tangible late Wednesday night as US president uttered the words 'America is addicted to oil' and that something must be done about it.
American Superconductor sues Sinovel for IP theft; Shares off

September 15, 2011 by Eric Savitz in Forbes Magazine
"AMSC believes that Sinovel illegally obtained and used AMSC's intellectual property to upgrade its 1.5 megawatt wind turbines in the field to meet proposed Chinese grid codes and to potentially allow for the use of core electrical components from other manufacturers."
Cheaper, user-friendly turbines could pave the way for more investment.
