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”.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
