A V90-3.0 MW offshore wind turbine has to produce electricity for just 6.8 months, before it has produced as much energy as used throughout its design lifetime. In other words this turbine model earns its own worth more than 35 times during its design lifetime.
Furthermore, compared to the V80-2.0 MW offshore wind turbine, the 6.8 months constitutes an improvement of approximately 2.2 months.
If installed on a good site, the V90-3.0 MW wind turbine will generate approximately 280,000 MWh in 20 years - thus sparing the environment the impact of a net volume of approximately 230,000 tons of CO2, as compared to the figures for energy generated by a coal-fired power station.
Svend Sigaard, President and CEO of Vestas Wind Systems A/S, finds that the positive results reflect that Vestas lives up to its goal of improving both the competitiveness and the environmentally friendliness of the wind turbines. “The life cycle assessments are used as a natural and important decision-making tool in product development and in the choice of production technology,” says Svend Sigaard and informs that Vestas plans to make life cycle assessments of all wind turbines in the product range.
“With life cycle assessments of our wind turbines, we have an excellent tool to compare the products and estimate how big an advantage our wind power systems are to the environment,” says Svend Sigaard.
The life cycle assessments for the V90-3.0 MW and V80-2.0 MW wind turbines are published on the Vestas Web site at www.vestas.com under the heading “Environment”.

Facts about the Vestas Group’s work with environment and occupational health & safety:
Vestas develops and manufactures wind power systems that generate sustainable energy for consumers throughout the world. In 2004, Vestas delivered 2,784 MW. The power generated annually by these turbines corresponds to the annual electricity consumption of approximately 2.1 million Danish households (Energistatistik 2003 (Energy Statistics 2003), which is published by the Danish Energy Agency, states that the average annual energy consumption of a Danish household is 3,430 kilowatt hours (kWh). The power generated annually by the turbines delivered by Vestas in 2004 corresponds to savings of approximately 4,009,000 tons of CO2 in relation to the average electricity generated in Europe. This calculation is based on the fact that the various other sources of electricity generation in Europe results in emissions of 548 grams of CO2 per kWh (source: Work report from the Danish Environmental Protection Agency No. 27, 2002). Vestas considers it natural for the Group to communicate its consideration for environmental and occupational health and safety aspects in the development, manufacture, sale, erection and service & maintenance of its wind turbines. That is why Vestas publishes an annual environmental statement that describes environmental and occupational health and safety aspects at Vestas Wind Systems A/S. The environmental statements are available on www.vestas.com under the heading ”Environment”.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
