Wind energy declines in USA

28 July 2010

Wind power installations to date this year have dropped by 71% from last years level, according to the latest quarterly report from the American Wind Energy Association (AWEA).

Only 700 MW of wind turbines were added in Q2 2010, down 57% from comparable 2008 levels and down 71% from 2009.

Even with 5.5 GW of wind power under construction and a more active second half of the year anticipated, AWEA projects that total 2010 installations will be 25% to 45% below 2009 installations, depending on policy developments.

Combined Q1 and Q2wind energy installations in 2010 are 1239 MW, 57% below 2008 half-year levels and 71% below 2009.

AWEA and a coalition of renewable energy, labor, utility and environmental groups are calling on the US Congress to enact a strong national renewable electricity standard (RES) to spur demand for green power, attract manufacturing investment and save (and create) jobs.

“Strong Federal policy supporting the US wind energy industry has never been more important,” says Denise Bode of AWEA. “We have an historic opportunity to build a major new manufacturing industry.”

“Without strong, supportive policy like an RES to spur demand, investment and jobs, manufacturing facilities will go idle and lay off workers if Congress doesn’t act now – before time runs out this session,” she adds.

US wind energy now in ‘coasting momentum’

There is no demand beyond the present “coasting momentum” and, without stable policy, without demand and new power purchase agreements and without new wind turbine orders, the domestic industry is sputtering out, the group notes. “Passage of a strong national RES will boost demand and fire up the industry’s economic engines.”

The US wind energy industry has repeatedly criticized the ‘boom-and-bust’ cycles which result in layoffs and also discourage investment in new manufacturing facilities. The USA is losing the clean energy manufacturing race to Europe and China, which have firm long-term renewable energy targets and policy commitments in place, warns AWEA.

According to a national poll conducted by Public Opinion Strategies, an RES is popular among US voters with strong support from 65% of Republican voters, 69% of Independents and 92% of Democrats.

OFFSHORE WIND ENERGY MEETS OFFSHORE WIND ENERGY STORAGE.
by Bruce Mulliken, Green Energy News

Eventually the United States will get its first offshore wind farm. No one is taking bets as to when it will go online. There have been many proposals, but so far resistance onshore has kept those projects from being built.

Still, wind resources are much better offshore than on and those windy resources are often near heavily populated areas that will be able and willing to consume electricity generated by those reliable ocean breezes.

As with many relatively expensive technologies it’s not such a bad thing to be a late adopter. Early adopters make and have to correct mistakes at a high cost. Early adopters too have only earliest versions of the technology to work with. Late adopters, on the other hand, learn from the mistakes of early adopters and need not repeat them. Late adopters also get to use newer, more sophisticated versions of the technology in question.

Offshore wind is one of those relatively expensive technologies that it’s OK to be a late adopter.

When U.S. offshore wind builders finally get around to planting the first turbine in the ocean bottom (or perhaps floating turbines in deep water over the horizon) they’ll have a better idea of the costs, know exactly how to install them and they’ll have access to far more powerful turbines than those used in the first offshore wind farms in Europe. The U.S. will benefit by being slow to adopt offshore wind, but the time has come to embrace the technology; wind developers know this, so does the U.S. government.

Even as dollars are being pinched in Washington, the Department of Energy has put aside $50.5 million for projects that support offshore wind energy development. The Department of the Interior too, in its Smart for the Start program, has given a hand to offshore wind development by designating four areas along the Mid-Atlantic coast to be on the fast track for regulatory approval.

The funding being offered by DOE can be used for the development of innovative wind turbine design tools and hardware to provide the foundation for a cost-competitive and world-class offshore wind industry in the United States (up to $25 million over 5 years); for baseline studies and targeted environmental research to characterize key industry sectors and factors limiting the deployment of offshore wind ( up to $18 million over 3 years); and for the development and refinement of next-generation designs for wind turbine drivetrains (up to $7.5 million over 3 years).

The Department of the Interior has chosen areas on the Outer Continental Shelf offshore Delaware (122 square nautical miles), Maryland (207), New Jersey (417), and Virginia (165) to receive early environmental reviews that will help to lessen the time required for review, leasing and approval of offshore wind turbine facilities.

Government isn’t alone in seeking to develop offshore wind.

Renewables are Growing Fast: What’s New?

Published: July 21, 2010

Paris — If you’re looking for a comprehensive resource for renewable energy installation figures, look no further: The Renewables Global Status report was released last week, and it provides a great snapshot of where and how renewables are being developed around the world.

The report was released by the Renewable Energy Policy Network for the 21st Century, also known as REN21, and it provides an upbeat picture for renewables, despite the murky outlook for the global economy.

The report was originally released in 2005. Since then, solar PV has grown by 60 percent annually, wind by 27 percent, solar hot water by 19 percent, according to the authors. In 2009, renewables made up more than half of investment in global power generation. And that’s with depressed oil and gas prices, lenders being very choosy about projects and individual consumers facing their own financial problems. Total investment in the industry was about $150 billion last year.

Other than the stellar investment figures during a slow year for most other industries, there’s not much surprising in the 2009 report. The industry continues to move along – increasingly in developing countries – driven largely by robust public policy. Where policy lacks, investment does too.

Perhaps the most important trend is the role of China in the global renewable energy market. According to the report, the country produces about 40 precent of solar PV panels, 30 percent of wind turbines and 77 percent of solar hot water systems globally. The Chinese presence will impact investment decisions of companies as they work to compete with “The China Price,” and decide where to locate manufacturing facilities.

Many organizations like the International Energy Agency and the Energy Information Administration put together yearly figures on renewables. But none do it quite as comprehensively and clearly as the REN21 folks do. It’s worth keeping around as a go-to resource for figures on the industry.

Here are some other highlights taken straight from the report about the various renewables sectors:

Energy Neutral Homes Are Not That Hard To Create – Here is one step

To Think At One Time: I did not even think I would get requests for guest posts. Then: I questioned whether to allow guest posts. Now I am getting a request about every month for someone to share this space…And you know what I love it.

It’s not necessary to become a nerd to find out how wind power works

Wind is the result of the uneven heating of the Earth by the sun and the fact that temperatures will always be attempting to reach an equilibrium (heat is always moving to a cooler area). With the rising price of energy and the damage to the environment from classic fuels, it is increasingly equitable to harvest this renewable resource.

The benefits of wind energy are that it’s virtually free (after you purchase the equipment) and there’s no pollution. The disadvantages include the fact it is not a constant source (the speed varies and many times it is insufficient to make electricity) and it typically requires about one acre of land.

How Wind Energy Works

The volume of power that can be found varies by wind speed. The amount available is named it’s power density which is measured in watts per square meter. Due to this, the U.S. Department of Energy has separated wind energy into classes from 1 to 7. The typical wind speed for class 1 is 9.8 mph or less while the average for a class 7 is 21.1 or more. For effective power production, class 2 winds (11.5 mph average speed) are usually required.

In general, wind speeds increase as you get higher above the Earth. Due to this, the typical wind mill comes with a tower no less than 30 feet above obstructions. That there are two basic different types of towers employed for residential wind power systems (free standing and guyed). Free standing towers are self supporting and are usually heavier which means they take special equipment (cranes) to erect them. Guyed towers are supported on a concrete base and anchored by wires for support. They typically are not as heavy and most manufacturer’s produce tilt down models which may be easily raised and lowered for maintenance.

The kinetic (moving energy) from the winds is harnessed by a device called a turbine. This turbine contains airfoils (blades) that capture the energy of the wind and use it to turn the shaft of an alternator (like you have on a car only bigger).

There are two basic types of blades (drag style and lifting style). We all have seen pictures of old-fashioned windmills with the large flat blades which are an example of the drag style of airfoil. Lifting style blades are twisted instead of flat and resemble the propellor of a small airplane.

A turbine is classified as to whether it is built to be installed with the rotor in a horizontal or vertical position and whether the wind strikes the blades or the tower first. A vertical turbine typically requires less land for it’s installation and is a better option for the more urban areas of the world. An upwind turbine is designed for the wind to impact the airfoils before it does the tower.

http://www.residentialwindturbines.org/residential-wind-turbine.jpg

These units ordinarily have a tail on the turbine which is needed to keep the unit pointed into the wind. A downwind turbine doesn’t need a tail as the wind acting on the blades tends to maintain it oriented properly.

These turbine systems would be damaged if they were to be permitted to turn at excessive speeds. Therefore, units will need to have automatic over-speed governing systems. Some systems use electrical braking systems although some use mechanical type brakes.

The output electricity from the alternator is sent to a controller which conditions it for use in the home. The use of residential wind power systems requires the home to either remain linked with the utility grid or store electricity in a battery for use when the wind doesn’t blow sufficiently.

When the home is tied to the grid, the surplus electricity that is produced by the residential wind power system can be sold to the utility company to lower and sometimes even eliminate your electric bill. During times with not enough wind, the home is supplied power from the utility company.

http://www.residentialwindturbines.org/wind-scheme-grid-tied.gif

The Cost of Wind Energy

Small residential wind power turbines can be an attractive alternative, or addition, to those people needing over 100-200 watts of power for their home, business, or remote facility. Unlike PV’s, which stay at basically the same cost per watt independent of array size, wind turbines get more affordable with increasing system size. At the 50 watt size level, for instance, a small residential power turbine would cost about $8.00/watt in comparison to approximately $6.00/watt for a PV module.

This is the reason, all things being equal, Photo voltaic is less expensive for very small loads. As the system size gets larger, however, this “rule-of-thumb” reverses itself.

At 300 watts the wind generator costs are down to $2.50/watt, while the PV costs are still at $6.00/watt. For a 1,500 watt wind system the cost is down to $2.00/watt and at 10,000 watts the price of a wind generator (excluding electronics) is down to $1.50/watt.

Getting bigger, going green

St. John’s expansion will be environmentally friendly

By Patrick Yeagle

As St. John’s Hospital is preparing to renovate its downtown campus, the 135-year-old Springfield institution is paying special attention to minimizing the project’s environmental footprint and maximizing local economic benefits.

On March 31, hospital officials announced a $162 million proposal to demolish certain old structures on the hospital’s campus and replace them with more modern surgery, pharmacy and patient areas.

Dave Olejniczak, chief operating officer at St. John’s, says the project will incorporate several cost-saving, environmentally friendly designs, such as paints, stains and adhesives with low toxin levels, energy-efficient light fixtures and natural lighting whenever possible.

“A little bit of it is an investment up front, but the majority of it is going to be a cost savings down the road, in particular when we focus on the glass elements around the facility itself,” he says. “With having the natural light, it’s going to reduce the amount of artificial light we have to generate.”

Recycling is a big part of the design as well. From the carpet made of recycled fibers to the reuse of scrap materials such as steel and wood, Olejniczak says the project will uphold the hospital’s “stewardship values.”

“Envitronmental stewardship, from a Fransiscan perspective, is ensuring that we’re using the resources that we’re currently given to the best of our ability, and to take what we have and reuse it or recycle it,” Olejniczak said.

Dear Editor:

I am writing to you regarding your brief article about St. John Hospital’s future building plans. It is laudable that they plan on making that building locally built and green. However I did not hear “state-of-the-art” speak included in that admittedly short article. First and foremost I hope the Hospital will perform a green tear down. We should be wasting as little as possible these days. Putting perfectly good materials in the landfill is no longer acceptable.

Second I hope they also perform a green rebuild so that everything in the new Hospital wing will be recycled. Finally I hope that the new wing will generate its own energy and be super efficient in its energy usage. If they use windows, please use windows that generate electricity. If they have a roof I hope that it has wind turbines on top and plenty of plants to absorb the water that lands there. I hope that they put in geothermal heating and cooling systems. This is after all about people’s health. If St. Johns becomes a beacon of how we can lead our lives without pollutants then they will be contributing to the over all health of our community.

As the article pointed out it is also about health care costs. Industry estimates are that if the medical community used energy efficiently they could cut our medical cost by 10 to 15%. That would be a huge benefit to us all.

Wind blows energy to area bank

Mount Pulaski wind

Crews work to install the blades on a 10,000-watt wind turbine being installed to help power the Farmers Bank of Mount Pulaski on the city square in Mount Pulask Wednesday.

Mount Pulaski, Ill. –

A high-tech wind turbine that can generate 10,000 watts of power was installed near Logan County’s oldest bank Wednesday.

The turbine, which sits atop a 120-foot tower, will supply about half, or possibly more than half, of the electricity used by Farmers Bank of Mount Pulaski.

The apparatus cost about $65,000, some of which will be offset by tax credits, said Rick Volle, president of Farmers Bank, which was established in 1872.

“There’s a lot of these going up on a larger scale. We think it’s something worth doing,” Volle said. “…We are figuring about a 12-year payoff on it, and it has a life of about 30 years.”

Installation of the turbine on the square in Mount Pulaski drew a crowd of about two-dozen people. They watched as a crane lifted the tower into the air and workmen slowly moved the base over to a concrete pad. The turbine, complete with blades, was already installed on top.

By 12:15 p.m., the tower and turbine were in place. It now stands across the street from the historic Mount Pulaski Courthouse where Abraham Lincoln argued cases.

“I guess it’s progress for our town, and the bank in particular,” said Mike Cyrulik, who watched the work from across the street. “I think it’s going to be a great addition to town.”

Cyrulik was one of the first people to stop and watch. When the big crane took over, more people came out from downtown shops to see the tower rise into the air.

“It’s pretty interesting for a little town,” Cyrulik said.

Mount Pulaski, about 25 miles northeast of Springfield, sits on a hill that rises above the surrounding farmland.

John Wyss, owner of Central Illinois Wind and Solar, the company that installed the turbine, said downtown Mount Pulaski is a good spot for the new technology.

Ann Arbor Veteran Affairs hospital gets wind turbine

By Steve Pepple

December 02, 2008, 7:06AM
Eliyahu Gurfinkel | The Ann Arbor NewsDarryl Snabes, left, and Jeff Means are responsible for the installation of a wind turbine on the roof of the VA Ann Arbor Healthcare System building. Snabes is the local project manager and Means the regional energy manager at the VA.

A small wind turbine now spins atop the Ann Arbor Veteran Affairs hospital, contributing to the hospital’s utility needs while satisfying a new federal requirement for renewable energy.

Hospital administrators installed the vertical turbine last month as part of an ongoing plan to generate about 7.5 percent of the hospital’s energy needs from renewable energy, including wind and solar, by 2012.

“It’s a baby step, but we’re optimistic,” said Jeff Means, energy manager for VA hospitals in Michigan and nearby states.

The turbine and its installation cost about $100,000. If it is successful in generating enough energy, the hospital could install additional turbines and solar panels to generate energy, Means said.

The turbine, which weighs about 1,000 pounds, is 16 feet tall and 3 feet wide. As the wind spins the vertical turbine, a generator in its base sends direct electrical current through several boxes to transform the power into alternating current to be used by the hospital.

Report says China is squeezing U.S. firms out of its massive wind-power market

12:00 AM CDT on Thursday, March 18, 2010

By JIM LANDERS / The Dallas Morning News
jlanders@dallasnews.com

WASHINGTON – U.S. companies are getting squeezed out of the big Chinese wind-power market even as Dallas investors are bringing Chinese firms here via a big wind farm in Texas, according to a new industry report.

“They’ve used every measure you could possibly think of to enhance production of renewable energy equipment in China,” said report author Alan Wolff of the trade law firm Dewey & LeBoeuf LLP.

U.S. Trade Representative Ron Kirk won a pledge from the Chinese last fall to drop rules giving preference to Chinese makers of wind-power equipment. But Kirk’s office hasn’t seen any evidence that the pledge has been carried out, said spokeswoman Carol Guthrie.

Meanwhile, Chinese manufacturers are entering the U.S. wind market under a joint venture led by Dallas investor Cappy McGarr.

McGarr’s U.S. Renewable Energy Group, with Cielo Wind Power LP of Austin and China’s Shenyang Power Group, is planning a $1.5 billion, 600-megawatt wind farm on 36,000 acres in West Texas.

Several U.S. senators have complained that the West Texas project would use hundreds of millions of dollars in U.S. economic stimulus funds for wind turbines built in China. They introduced a bill this month that would halt federal funding of renewable energy projects until “buy American” requirements are written into law.

McGarr’s Chinese partners announced plans last week to build a wind turbine factory in Nevada, and McGarr says most of the jobs for the West Texas project will be American.

“A minimum of 70 percent of each wind turbine in the … project, including the massive towers and blades, will be wholly manufactured in the United States and made entirely of American steel,” McGarr said.

Dewey & LeBoeuf’s report on China’s renewable energy equipment market was done for a U.S. industry group, the National Foreign Trade Council, where concern about China’s market restrictions and treatment of foreign firms is growing.

“If you’re not operating under a rule-of-law country, if you have no place to adjudicate, and there are places where the country has stacked the deck against you, you may look for somewhere else” to do business, said trade council president Bill Reinsch.

Some wind power advocates are urging everyone to calm down and are particularly concerned about the Senate “Buy American” bill.

“This proposal would torpedo one of the most successful job creation efforts of the Recovery Act [the economic stimulus program], which has already preserved half of the 85,000 American jobs in the U.S. wind industry,” said Denise Bode, president of the American Wind Energy Association.

An Energy Audit Leads Directly To Wind Generation – People get the bug

Even Boulder Finds It Isn’t Easy Going Green

By STEPHANIE SIMON

BOULDER, Colo.—This spring, city contractors will fan out across this well-to-do college town to unscrew light bulbs in thousands of homes and replace them with more energy-efficient models, at taxpayer expense.

City officials never dreamed they’d have to play nanny when they set out in 2006 to make Boulder a role model in the fight against global warming. The cause seemed like a natural fit in a place where residents tend to be politically liberal and passionate about the great outdoors.

Instead, as Congress considers how to encourage Americans to conserve more energy, Boulder stands as a cautionary tale about the limits of good intentions.

“What we’ve found is that for the vast majority of people, it’s exceedingly difficult to get them to do much of anything,” says Kevin Doran, a senior research fellow at the University of Colorado at Boulder.

President Barack Obama has set ambitious goals for cutting greenhouse-gas emissions, in part by improving energy efficiency. Last year’s stimulus bill set aside billions to weatherize buildings. The president has also called for a “cash for caulkers” rebate for Americans who weatherize their homes.

But Boulder has found that financial incentives and an intense publicity campaign aren’t enough to spur most homeowners to action, even in a city so environmentally conscious that the college football stadium won’t sell potato chips because the packaging isn’t recyclable.

Take George Karakehian. He considers himself quite green: He drives a hybrid, recycles, uses energy-efficient compact fluorescent bulbs. But he refuses to practice the most basic of conservation measures: Shutting the doors to his downtown art gallery when his heating or air conditioning is running.

DISTRIBUTED GENERATION AND ITS SOCIAL IMPACT
By Manu Avinash .G , S4, EEE, CET and
Krishna kumar .G , S4, EEE, CET

ABSTRACT- distributed generation, defined as generation located at or near the load centres, is being recognised as an environment friendly, reliable, and secure source of power which not only has minimal negative social impacts but also serves to promote social welfare. This paper aims to bring out the salient features of distributed generation from an economic and social perspective. The paper to identify the distributed resources available in India and proposes methods to tap them. It also studies the social consequences of wide spread deployment of distributed systems and their accommodation into the new liberalised energy market of India.

I. INTRODUCTION
Most of the electricity produced today is generated in large generating stations, which is then transmitted at high voltage to the load centres and transmitted to consumers at reduced voltage through local distribution systems. In contrast with large generating stations, distributed generation (DG) produce power on a customer’s site or at a local distribution network. DG technologies include

  • Engines,
  • Small hydro and gas turbines
  • Fuel cells
  • Photo voltaic systems etc


Although they represent a small share of the electricity market they play a key role for applications in which reliability is crucial, as a source of emergency capacity, and as an alternative to expansion of a local network, in developed economies where uninterrupted power supply is essential. In developing countries like India, where the generation is inadequate to meet the demand, reliability and energy security are of lesser importance. Developing country can tap the potential of DG to extend their present generation capacity in an environment friendly and cost friendly manner.

The paper is divided into two parts first part examines the various DG technologies and their merits and demerits and the second part studies the social impact of large scale deployment of small, mini and micro projects in India.

II. WHAT IS DISTRIBUTED GENERATION?
Distributed generation, is defined as generation located at or near the load centres [1]. They generate electricity through various small-scale power generation technologies. Distributed energy resources (DE) refers to a variety of small, modular power-generating technologies that can be combined with energy management and storage systems and used to improve the operation of the electricity delivery system, whether or not those technologies are connected to an electricity grid. . Projects are generally developed by either the user to avoid the purchase of power from the grid or an energy service provider who then retails the power to the site.

III. DISTRIBUTED GENERATION TECHNOLOGIES
Commercial energy technologies include:

  • IC engines
  • Gas turbines
  • Micro turbines
  • Energy storage technologies


Renewable energy technologies include:

  • Fuel cells
  • Solar photovoltaic
  • Wind & Wave Energy
  • Hydro electric energy


Some of them are discussed below:

Don’t take their word for it. Pretty much everybody now agrees that it has its place in the world.

http://www.dg.history.vt.edu/ch1/benefits.html

What are the Potential Benefits of DG Systems?

Consumer advocates who favor DG point out that distributed resources can improve the efficiency of providing electric power.  They often highlight that transmission of electricity from a power plant to a typical user wastes roughly 4.2 to 8.9 percent of the electricity as a consequence of aging transmission equipment, inconsistent enforcement of reliability guidelines, and growing congestion. At the same time, customers often suffer from poor power quality—variations in voltage or electrical flow—that results from a variety of factors, including poor switching operations in the network, voltage dips, interruptions, transients, and network disturbances from loads.  Overall, DG proponents highlight the inefficiency of the existing large-scale electrical transmission and distribution network.  Moreover, because customers’ electricity bills include the cost of this vast transmission grid, the use of on-site power equipment can conceivably provide consumers with affordable power at a higher level of quality.  In addition, residents and businesses that generate power locally have the potential to sell surplus power to the grid, which can yield significant income during times of peak demand.

Industrial managers and contractors have also begun to emphasize the advantages of generating power on site.  Cogeneration technologies permit businesses to reuse thermal energy that would normally be wasted.  They have therefore become prized in industries that use large quantities of heat, such as the iron and steel, chemical processing, refining, pulp and paper manufacturing, and food processing industries.  Similar generation hardware can also deploy recycled heat to provide hot water for use in aquaculture, greenhouse heating, desalination of seawater, increased crop growth and frost protection, and air preheating.

Beyond efficiency, DG technologies may provide benefits in the form of more reliable power for industries that require uninterrupted service.  The Electric Power Research Institute reported that power outages and quality disturbances cost American businesses $119 billion per year.  In 2001, the International Energy Agency (2002) estimated that the average cost of a one-hour power outage was $6,480,000 for brokerage operations and $2,580,000 for credit card operations.  The figures grow more impressively for the semiconductor industry, where a two hour power outage can cost close to $48,000,000.  Given these numbers, it remains no mystery why several firms have already installed DG facilities to ensure consistent power supplies

We have so much coastline that we could use for this. But nooooo, the drill here drill now crowd would rather put drilling rigs there. First I have to say:

New offshore wind farm contracts announced

Offshore wind farm

The licences could see the installation of hundreds of new turbines

Contracts have been awarded for a major expansion of offshore wind power in the seas around Scotland.

Moray Offshore Renewables and SeaGreen Wind Energy will develop offshore wind power in the Moray Firth and the Firth of Forth.

The energy companies have been awarded the contracts by the Crown Estate, a UK government agency.

It is believed the development could lead to 1,000 new turbines generating nearly five giga watts of power.

Jobs could also be created in manufacturing, research, engineering, installation, operation and services.

The move comes just days after the Scottish government’s approval of the controversial upgrade to the Beauly to Denny transmission line of pylons from the Highlands to central Scotland.

We hold a competitive advantage in developing offshore renewables, including as much as a quarter of Europe’s offshore wind energy potential and a world-class scientific capacity and skills base

First Minister

First Minister Alex Salmond said: “The announcement by the Crown Estate is excellent news for Scotland.

“We hold a competitive advantage in developing offshore renewables, including as much as a quarter of Europe’s offshore wind energy potential and a world-class scientific capacity and skills base.”

Scottish Secretary Jim Murphy said Scotland was the windiest country in Europe and the conditions were being created for the energy industry to invest in harnessing it.

He added: “This is one of the strongest signals yet that Scotland is right at the heart of the UK’s commitment to a low carbon, energy secure, prosperous future.

“But it’s also great news for the manufacturing industry and supply chain in Scotland.”

‘Great opportunity’

The Crown Estate is the owner of the UK’s coastal seabeds and this third round of grants covers the Moray Firth zone, which will be developed by a partnership involving the Portuguese company, EDP Renewables and SeaEnergy.

Wind power in Scotland

From Wikipedia, the free encyclopedia

Jump to: navigation, search

Wind power in Scotland is an area of considerable activity, with 1550 MW of installed capacity as at October 2008.[1] Wind power is the fastest growing of the renewable energy technologies in Scotland and the world’s largest wind turbine generator (5 MW) is currently undergoing testing in the North Sea, 15 miles off the east coast. There are numerous large wind farms as well as a number, both planned and operating, which are in community ownership. The siting of turbines is sometimes an issue, but surveys have shown high levels of community acceptance for wind power in Scotland. There is further potential for expansion, especially offshore, given the high average wind speeds.

The Scottish government has a target of generating 31% of Scotland’s electricity from renewable energy by 2011 and 50% by 2020. The majority of this is likely to come from wind power.[2]
