WIND POWER INDIA 2011 International Conference & Exhibition 7-9 April 2011

World institute of Sustainable Energy (WISE) planning to organize  WIND POWER INDIA 2011 International Conference & Exhibition in Chennai, 7-9 April 2011.  It is the first-of-its-kind international wind event to take place in India. It is the international counterpart of India’s coveted national wind event, WIND INDIA, which was launched in 2006 in Pune, India, by the renowned sustainability think-tank, the World Institute of Sustainable Energy (WISE). Following its resounding success, WISE decided to hold the event on a biennial basis, and this gave rise to the second WIND INDIA event in 2008 in Chennai, India. Read More

Why wind speeds have slowed ?

Wind speeds have slowed over three decades across the Northern Hemisphere.

Increasing amounts of vegetation could be causing up to 60% of a slowing in wind speed across the Northern Hemisphere, according to researchers analysing three decades of wind-speed data in Nature Geoscience1 today. 

The decline is a potential concern for wind-turbine efficiency. But researchers cannot tell whether the effect, an average 10% slowdown, will make much difference to wind turbines — the slowing winds measured are at 10 metres above the ground, whereas turbines operate at 50–100 metres up, where there is little global data.

Several previous regional studies looking at the United States, Australia, China and parts of Europe have shown decreasing wind speeds just above the planet's surface. Climate change, afforestation and urban development had been mooted as possible causes. But, says Robert Vautard, at the University of Versailles Saint Quentin in Yvelines, France, "people always said the data were rubbish. There was no quality-controlled global archive of data." 

Vautard and his colleagues collected data from about 10,000 weather stations, although they removed all but 822 stations from their list because of incomplete records. That left records stretching back to 1979, taking in Europe, central Asia, eastern Asia and North America. 

Vautard had expected a study spanning such a large area to show speeds increasing in some areas and decreasing in others. But, he says, "we were surprised to see a very clear trend across the whole Northern Hemisphere". Annual wind speeds had declined at 73% of the stations, dropping by 5–15% over almost all of the land areas examined. The most pronounced effect was seen across Eurasia. The researchers also found that stronger winds have been affected more than weak ones. 

Brian Golding, director of forecasting research at the UK Met Office in Exeter, Devon, says that the observation is interesting. "However," he adds, "the timescales are very short for a meteorological trend — it's entirely possible that the previous 30 years would show a different trend."

Vautard counters that the few available records dating back to 1959 suggest that the trend had been developing since the 1960s.

Total installed capacity of all wind turbines installed worldwide reached 175 Gigawatt in mid-2010

Latest news we got that the total capacity of all wind turbines installed worldwide reached 175 Gigawatt in mid-2010, compared with 159 Gigawatt by the end of 2009. 

WWEA expects that the market for new turbines will reach a size between 35 and 40 Gigawatt in the year 2010, close to 2009 when 38 Gigawatt were added. With this increase, the global capacity will reach almost 200 Gigawatt by the end of this year. With an expected total increase of 15 GW in the year 2010, China will most likely become number one country in terms of total capacity by the end of 2010, thus surpassing the USA.

The world market for wind turbines saw robust growth in the first half of the year 2010, with approximately 16 Gigawatt of new capacity added worldwide. Again China represents by far the largest market and added 7800 Megawatt within only six months, reaching total installations of almost 34 Gigawatt. 

The USA, still number one in total capacity with 36 Gigawatt, saw a major decrease in new installations and added only 1200 MW, followed by India. The five major European markets showed similar growth: Germany added 660 Megawatt, France and the UK 500 Megawatt, Italy 450 Megawatt and Spain 400 Megawatt. 

Germany Launched 5 MW Wind Turbine

Germany Launched  "5M" wind turbine, which is designed and built by Germany's REpower Company.  This Wind Power Turbine officially launched at a dedication event in Germany this week with over 600 guests from business and politics. 

Germany country now emerging as one of the strongest wind power markets in world. In figures, wind power already meets more than 30 percent of the electricity demand in the German states Schleswig-Holstein and Mecklenburg-Western Pomerania. 

The largest wind turbine in the world, a 120-meter (394-feet) capable of generating 5 MW at full output has officially inaugurated and connected to the German electrical grid.

Inside The Wind Turbine

Wind turbines convert wind energy to electricity for distribution. Conventional horizontal axis turbines divided into three major components.

• The Rotor Component : Rotor Component is approximately 20% of the wind turbine cost, which includes the blades for converting wind energy to low speed rotational energy.
  
  
• The Generator Component : The generator component is approximately 34% of the wind turbine cost, which includes the electrical generator, the control electronics, and most likely a gearbox component for converting the low speed incoming rotation to high speed rotation suitable for generating electricity.
  
  
  
• The Structural Support Component : The structural support component is approximately 15% of the wind turbine cost, includes the tower and rotor yaw mechanism.
  
  Wind turbines are specially designed to generate energy from the blowing wind that exists at any point of location.  Aerodynamic modeling is used to determine the optimum tower height, control systems, number of blades and blade shape.
