Danish and Dutch wind energy policy 1970–2000: lessons for the future
Both in the Netherlands and in Denmark, policies to develop a wind turbine industry and to install a large wind turbine capacity were started in the 1970s. However, the outcomes of these policies were very different. A flourishing wind turbine industry developed in Denmark, whereas in the Netherlands, a few companies started building wind turbines in the 1980s and 1990s, but presently no wind ...

Evaluating Sustainability of Wind Energy: Fact-Based Insights Through LCA
Decarbonization of the power sector plays a key role in achieving climate neutrality and net-zero targets in line with the 1.5ºC goal of the Paris Agreement. Therefore, the rapid transformation from fossil to renewable energy sources such as wind or solar is becoming increasingly important and crucial for countries aiming for ambitious climate targets. Despite the global pandemic, the ...

What’s the Future of R&D in the Wind Industry?
When the wind industry finally reacted to the world’s financial crisis—it didn’t fully hit us until 2010—at once, we lost both an incredibly vibrant global wind market and sufficiently robust profit margins. The market recovery is rebounding nicely now, thanks largely to government incentives, but profit margins will probably never fully recover—at least, not to the ...

Wind turbine technology leaps set to slice maintenance costs
Self-diagnosing turbines, real-time output maximization and “crane less” maintenance will soon impact wind operations, cutting labour costs and increasing generation revenue, Denver Bane, Onshore Wind Services Strategy Leader at GE Renewable Energy, told the Wind Operations Dallas 2019 conference. Intense competition in the wind market is spurring turbine developers to find new ...

Modelling and control of a variable speed wind turbine driving doubly fed induction generator using three–level PWM converter
The aim of this researcher is to develop a complete wind central model driven doubly fed induction generator (DFIG) which feeds an AC power grid. For that, two–pulse width modulated (PWM) voltage converters are connected back to back between the rotor terminals of DFIG and the utility grid via a common DC link, in there, our contribution will appear in the utilisation of three levels voltage ...

Data–driven modelling, control, and fault detection of wind turbine systems
In this paper, data–driven system modelling, control, and fault detection technique for wind turbine systems are researched. The developed algorithm is to recursively update system parameters using predictor–based system identification (SID) technique. Updated system parameters are used to design subspace predictive controller for wind turbine systems with constraint on pitch angle and generator ...

Prospect of offshore wind energy development in Japan
In Japan, the cumulative capacity of wind turbine generation systems on land has increased steadily in recent years. To install a large number of wind turbines has inherent problems such as shortage of suitable land, and inadequate infrastructure such as power cables and roads. The necessity for development of offshore wind turbine generation systems has been recognised based on the above ...

Air concentrating nozzles: a promising option for wind turbines
Although the use of wind turbines has become necessary in many parts of the world, the actual developments in wind turbines do not concern countries where the average wind speeds are low. The paper introduces a new vertical axis wind rotor using a convergent nozzle for low wind speed areas. This paper brings a detailed theoretical and practical study of air concentrating nozzle and the optimum ...

Life cycle assessment of a 150 MW offshore wind turbine farm at Nysted/Roedsand, Denmark
The purpose of this life cycle assessment (LCA) was to illuminate and describe the potential environmental impacts caused by an offshore wind turbine farm (WTF) throughout its lifetime and use this knowledge in the planning and improvement of future WTFs. The LCA was based on experience from the LCA on Danish electricity and district heating [1] as well as the offshore WTF project at ...

Performance estimation of HAWT blade using NACA airfoils
Wind energy is one of the developing resources of renewable energy. In order to increase the use of wind energy, development of wind turbine blade with higher power coefficient plays a vital role. The work being presented here is to give new design of blade for VESTAS V82–1.65MW (HAWT). In this work, NACA airfoils are used for the determination of aerodynamic performance characteristics of ...

The future of wind turbines could be bladeless
With their considerable height and large blades turning almost hypnotically, wind turbines have become an iconic symbol of the planet's shift to renewable sources of energy. In Spain, however, one business is looking to design wind generators that produce renewable energy without blades. "Our goal is to develop a new wind generator that minimize(s) the amount of mechanical elements to reduce ...

The advantages and disadvantages of wind energy
The wind power generation is developing fast during the past several years. As a source of Green energy is a possible solution for the energy crisis in the near future. But it's not a perfect type of energy without any drawbacks. So, let's look into this type renewable energy for get some more idea. Advantages: 1. Wind energy is clean energy, consuming no fossil fuels to generate electricity. ...

Wind turbine controlling of the future
Higher, more robust, more reliable: Parallel to the growing requirements for wind turbines, the requirements for monitoring sensors grow as well. But how can wind sensor manufacturers fulfil these wishes? And how should a future wind sensors look like? After analysing the current conditions and trends on the wind energy market, our CEO Klaus Hirzel compiled a wish list for future wind sensors. ...

10 Facts you didn’t know about Wind Energy
The oldest rotary windmills are considered to have been used regularly in agriculture and other purposes since 2000 B.C. by peoples of what would today be China and the Middle East who already sensed what the German physicist Albert Betz, the father of physics governing modern wind turbines, called The Theory of Wind Energy, presented and published in his book “Wind-Energie” at the ...

The solar storm run - 20% more power at 25% lower costs within 15 months
Photovoltaic storm run: 20% more power at 25% lower costs for modules within 15 months. Frankfurt am Main, September 26, 2012: At the time (as editor) I invited pv magazine to a breakfast event during the EUPVSEC. The topic polarized: 300 GWp / a photovoltaics worldwide in 2025, for Germany a total of max. 200 GWp. As can be seen today: too conservative for Germany, but well on the global stage. ...
