Wind energy market saw decreased demand in 2010

In 2010 the U.S. wind energy market took a hit with a decrease in investment compared with 2008 and 2009.

According to the Department of Energy’s, the report investment in terms of how much wind energy capacity was built and connected to the national electric grid.

In U.S. in 2010 were installed about 5 gigawatts’ worth of wind energy farms representing an $11 billion investment, according to the report.

Compare to the 10 gigawatts that were installed in 2009 in the U.S., and the 8 gigawatts in 2008, 2010 represents a decrease in wind energy installations.

“The combination of the delayed impact of the global financial crisis, relatively low natural gas and wholesale electricity prices, and slumping overall demand for energy outweighed the ongoing availability of existing federal and state incentives for wind energy deployment, resulting in a steep drop in capacity additions relative to both 2008 and 2009,” according to the
report.

China was the world’s fastest-growing market and U.S. was still the second-fastest-growing wind energy market in the world in 2010.

Wind turbine component manufacturing in the U.S. grew in 2010 and about 68 percent of components used in U.S. wind projects installed between 2009 and 2010 were made in the U.S.

Reports regarding wind market

America’s wind power industry grew 15 per cent last year, according to a new industry report which warned that the sector’s expansion was held back by weak electricity prices and unpredictable policies.
The American Wind Energy Association (AWEA) yesterday unveiled its US annual report, showing that 5,116MW of new capacity was added last year, taking the total volume of US installations to 40,181MW, now generating enough electricity to power more than 10 million homes.
However, despite the increase in capacity, last year’s growth was significantly lower than the average 39 per cent growth rate recorded in the previous five years.
The sector blamed weak electricity prices and investor uncertainty caused by doubts over whether key federal tax incentives would be extended for the relatively sluggish performance.
The report follows recently released figures from the Global Wind Energy Council (GWEC) which show that in 2009 China overtook the US in terms of the volume of new installations and manufacturing of wind turbines for the first time.
Denise Bode, AWEA chief executive, remained optimistic that the US was on track to produce 20 per cent of America’s electricity by 2030 from wind energy, as predicted by the Department of Energy during the Bush administration.
“The American wind industry is delivering, despite competing with energy sectors that have permanent government subsidies in place,” she said. “Wind is consistently performing … adding 35 per cent of all new generating capacity since 2007- that’s twice what coal and nuclear added combined.”
On top of new construction starts, the industry brought 14 new manufacturing facilities online in 2010, consistent with 2009, meaning that wind energy now accounts for up to 20,000 manufacturing jobs across 42 states.
“Continued interest and investment by manufacturers in America demonstrates that the US continues to be a global powerhouse for wind development, today and in the future,” Bode added.
Meanwhile, a separate report released by GWEC has this week argued that India’s potential for wind power development is higher than previously calculated, and could reach 65.2GW by 2020, up from 13.1GW at the end of 2010.
According to the Indian Wind Energy Outlook 2011, published yesterday by GWEC,  the World Institute of Sustainable Energy and the Indian Wind Turbine Manufacturers Association (IWTMA), India’s potential for wind power development could exceed 100GW, reaching 160.7GW by 2030, if the potential of offshore wind power and repowering was fully exploited.
Achieving 65.2 GW of wind capacity by 2020 would attract around $10.4bn of annual investment to the sector and create 170,000 new jobs.

Energy provided by passing trains

Rail travel is one of the greenest means of traveling across the country, but it could be even more efficient if the infrastructure itself produced electricity. Companies have already come up with plans to harness energy from passing trains using piezoelectric pads, and now two designers have developed a device that could harness the wind energy produced by speeding trains.
Ale Leonetti Luparinia and Qian Jiang’s T-Box is a power generator that captures wind energy from passing trains. It is designed to be installed into the spaces between existing rail tracks – around 150 T-Boxes could hypothetically be installed over 1km of track.
A passing train travelling at 200 kph would produce a wind speed equivalent to 15 m/sec. The T-Box would be able to catch this wind and produce about 3,500 W of power. If the train was 200m long, going at a speed of 300 kph and travelled 1km in 18 seconds, the T-Boxes would be able to produce about 2.6 KWh. This energy could then be utilized to power remote areas that don’t have electricity or rail sub-systems.

Vestas has plans for building a giant turbine in UK

Vestas has hinted it is considering building a new manufacturing facility in the UK, after unveiling the long-awaited design for its first wind turbine designed specifically for the next generation of offshore North Sea projects.
The world’s largest wind turbine manufacturer today launched the new V164-7.0MW turbine, which is 1MW larger than anticipated – and 1MW larger than the offshore turbines planned by rivals Siemens and General Electric.
Speaking at the launch of the turbine design in London today, Vestas chief executive Ditlev Engel said the company will require a new production facility for the 7MW machine at an undecided coastal location if it secures enough orders.
“This is an investment we are ready to make, but only if we see firm commitment from our customers,” he said. “A commitment that is backed by the political framework.”
Vestas Offshore president Anders Søe-Jensen confirmed the company’s Isle of Wight research and development centre will produce the V164’s 80 metre blades, each weighing 35 tonnes.
He also hinted the UK would be a strong contender for any new manufacturing site for the remaining components.
“[In order to lower costs] we need to build offshore where the wind resources are best, and that happens to be right here at our doorstep in the North Sea,” he said. “The ambitions and the volume definitely seem to be in the UK, but it is vital for the UK not to lose the first-mover momentum. Not least to address the energy gap at the end of the decade, but also to maximise possible job creation benefits.”
Weighing about 800 tonnes and standing at 187 metres high, the giant turbine constitutes Vestas’ largest ever research and development investment. It is expected to be able to produce enough electricity in one hour to supply one and a half households for a year.
The first prototypes are slated for construction in the fourth quarter of 2012, with serial production expected to start during the first quarter of 2015.
