The first floating wind was opened in North Sea

The first wind that floats on water has been inaugurated in Norwegian waters in the North Sea.

Called Hywind, the turbine is 65 meters tall and weighs 5,300 tons. The first such device that can be used even in deep waters 120 to 700 meters.

Hywind will begin to produce energy in a few weeks, the filmmakers say the project.

The technology could be used by countries like Japan, South Korea, the United States and Spain.

Technology: wind energy - at our disposal

The ambitious project was started two years ago over the U.S. by NREL (National Renewable Energy Laboratory in translation-free "National Renewable Energy Laboratory) in partnership with Xcel Energy, having as main objective testing and perfecting a system of generating electricity based on wind energy removing its main drawback: because of inconsistency which energy is available when it is most needed.

As time can not be controlled, the solution came as a way of storing electricity. Thus, regardless of the hours that the wind would blow with its maximum power, energy will be accumulated and used at the appropriate time (if the application itself, it will be returned to the national grid power during peak consumption) .

2.5 XL Wind turbines from GE Energy have the capacity for extremely low temperatures

The most advanced wind turbine from GE Energy 2.5-XL, is now available with a package for extremely low temperatures (CWE).
Adding package CWE guarantee operation of 2.5 xl wind turbines at low temperatures up to -30 ⁰ C, and in regime survival, without being put to work at temperatures up to -40 ⁰ C. CWE package is particularly important for wind turbines to work in Canada, where low temperatures are common.


Earlier this year GE announced that turbines of 2.5 xl, already enshrined in applications in Europe and Asia, will be released in North America in 2010. Initially, CWE package was developed for wind turbines of 1.5 megawatts (MW) and was adapted for turbines 2.5 XL, that the latest product of technology developed for wind turbine company.
"With over 4,400 wind turbines installed in locations characterized by low temperatures, GE has a long experience on the implementation of the turbines in adverse conditions," said Victor Abate, vice president of renewable resources, GE Energy. 2.5xl turbines are the most advanced technology of GE wind turbines in terms of efficiency, reliability and ability to connect to the network.

They are designed to ensure the highest annual energy production of their class and builds on the success of the 1.5 MW wind turbines from GE, that is most commonly used wind units in the world, currently being installed over 12,000 such turbines. The generator 2.5 MW turbines of 2.5 xl can provide a higher production projects on a smaller field and the High performance thanks to their sound over distances of kickback noise receptors can be minimized, allowing the installation of a number more units on a given area of land.

"Despite global economic challenges, we see further opportunities for sustainable growth in North American wind industry," said Abate. "Adding the package for extremely low temperatures in our model of 2.5 xl greatly expanded our ability to handle various needs of our customers.

According to the Canadian Wind Energy Association (CanWEA), Canada has surpassed last year's installed wind energy capacity of 2,000 megawatts and is expected to exceed 3,000 megawatts in 2009. Currently, wind power provide about 1% of Canada's electricity needs, wind turbines in this country representing a production capacity of over 2,800 megawatts, enough to meet the needs of over 860,000 homes. Province of Ontario is currently the leader in wind energy segment in Canada, with an installed capacity of 1162 megawatts, providing clean electricity for 300,000 homes.
Currently, GE has a strong presence in the wind industry in Canada, with an installed base of 938 MW (39%) nationwide and 780 MW in Ontario (62%). Also, GE is a major supporter of the initiative "WindVision 2025" the association CanWEA collaboration with federal and provincial partners in order to ensure the 20% of Canada's electricity on wind power by 2025, thereby reaching a total of approximately 52,000 new jobs "green" and new investments worth 79 billion nationwide.

1 billion dollars in renewable energy

Billionaire George Soros said it would invest 1 billion U.S. dollars in renewable energy technologies and create an organization that would advise the authorities on environmental issues, reports Bloomberg.
Soros, founder of Soros Fund Management LLC Fund, was announced Saturday in Copenhagen, during a seminar on climate change.

"I want to apply clear criteria such investments will be profitable, but to and contribute to solving problems (climate change)," Soros said in an e-mail quoted by Bloomberg News Sunday.

Soros, aged 79 years, not given, but details about the type or purpose investments that could be done, but said that the organization will establish Climate Policy Initiative, which will donate 10 million U.S. dollars each year in next ten years.

The organization will provide "Partial advisory services, partly to develop environmental policies and partly to carry out surveillance", he said the initiative, Thomas Heller, who is a professor at Stanford University Law School and an expert in energy and environmental legislation applicable.

The organization will develop programs on climate change and will operate in the U.S., Europe, China, India and Brazil.

"Matter with global warming is primarily a political today," Soros said, adding that the organization will deal with issues such as trade and the carbon rights.

Soros said he prefers the taxes applied to emissions of greenhouse gas trading system for carbon emissions, which is practiced in Europe, because it can be manipulated by investors.

Will the world become better, in the sense that we looked to what surrounds us .... to nature???

Which means wind energy

Wind energy is a source of renewable energy generated from wind power.Winds up not because the sun heats the earth uniformly, which creates air movement.Energy from wind, which is a kinetic energy can be used to turn over some turbines which are capable to generate electricity.It is supposing that the global potential of wind energy could provide five times more energy than is now consumed.
Advantages:

-are not pollutants emitted,that does not burn fuel, are spins palettes of the kinetic energy produced by wind.

-also do not produce waste.

-at the end of the operating turbine, it is removed from service at minimal cost, it can also be fully recycled.

-Wind energy is also very cheap.
Disadvantages:

-Wind speed variation

-Various people say that pollute both visual and sound
