Turbines

The tallest wind turbines in the U.S. have been installed in Texas — the Vestas V90 turbines are 345 feet(105.156 meter) high, and are rated at 3 megawatts each. They are part of the 63 megawatt Snyder Wind Project, a wind farm that’s just been installed in western Texas.Texas is already home to Horse Hollow, the world’s largest wind farm with 421 wind turbines that generate a total capacity

The mayor announced this week that the city is asking companies to come up with clean energy ideas, including wind power to fuel NYC. The city, released a Request for Expressions of Interest that will call for innovative ideas to help New York City develop sources of renewable energy. Mayor Bloomberg speaking at an energy summit in Las Vegas this week spoke about the possibility of placing wind tu

AES Proposes BEC Switch To Natural Gas: By Quincy Parker - Nassau, Bahamas: AES Corporation – which wants to build an LNG plant in The Bahamas – could potentially help the Bahamas Electricity Corporation (BEC) both save millions in fuel costs and become more environmentally friendly, the company spokesman contends. AES has estimated – based on New York Mercantile Exchange (NYMEX) foreca

Thousands of new wind turbines could be built across the UK over the coming decade as part of a radical £100 billion blueprint being unveiled to boost renewable energy and reduce greenhouse gas emissions.Business Secretary John Hutton acknowledged that the "green" power plants would cost more money and take up more land than conventional electricity generation, but said Britain had "no choice" ab

Gamesa has reached a landmark deal with Iberdrola Renewables, involving the largest ever purchase and sale agreement of wind turbine generators, amounting to a total power of 4,500 megawatts (MW). The purchase will come about between 2010 and 2012 and they will be destined to wind energy promotions in Spain, the rest of Europe, the United [...]

Architectures are each more concerned about environment, the new architectural concept is incorporate renewable energy in the buildings, the main purpose is to make sustainable buildings. Wind turbines is been the solution to generate energy needed for the buildings. One example is the Bahrain World Trade Center, this Trade Center is constituted by two towers, and between [...]

A column published in 2004 contained concerns raised by naturalists that birds were being killed by wind turbines. It is true that birds have been killed by the machines. Every product has a negative side, but every product has room for improvement, and better development. More: continued here

The UR-202 Hammerhead Automatic from Urwerk isn’t your everyday timepiece, no this particular watch, screams prolificness. By utilizing a unique winding system that’s regulated using compressed air, The 202 uses miniature twin turbines to control the rate of automatic winding and the level of air compression. Those functions can then be managed using a 3-position [...]

Clipper Wind is taking the plunge into a leadership position for offshore wind development. The Britannia project, announced last fall as a path toward testing super-sized offshore wind turbine system, will be announcing the first sale of a 7.5 megawatt wind turbine for deployment and testing in UK waters. These turbines are a touch bigger than Enercon's E-126 turbines. Enercon's turbines max out at about 7 megawatts. Clipper's turbines will take advantage of the high and steady winds of the UK's oceans to pull another 500 kilowatts.Showing the power of targets for creating opportunities, the UK's aggressive 2020 targets for renewable power and the vision of wind power's central role in meeting these targets has drawn Clipper and other companies into the United Kingdom to help meet the dem

I recently read that off the coast of Florida tons of water rushes by in a strong, smooth current, never pausing, never stopping. This energy can be harnessed with turbines, and would equate to 10 nuclear power stations, capable of supplying power to (I believe) 1/3 of Florida. What if we did that all over every continental coastline? What if we installed turbines throughout the majority of the ocean? We'd have tons of free, clean energy!It seems like every couple of months, a new energy option is revealed. I'm starting to think we are fully capable with current technology of detaching from oil permanently. Let's hope we do it in time.

Britain's defence ministry has raised objections over proposals to ramp up the proportion of the country's energy produced by wind farms, because of concerns over the impact of the turbines on military radar, The Times reported on Monday.A spokesman for Britain's business ministry conceded there had been "issues" regarding potential sites for wind farms, and military radar systems.The Ministry of Defence (MoD), however, insisted that all applications for new wind farms would be assessed on a "site-by-site" basis."The MoD is committed to government targets for renewable energy and whenever possible we seek to work with wind farm developers to find a mutually acceptable solution," an MoD spokesman said.According to The Times, the defence ministry has objected to at least four proposed sites

The Economist recently featured an article (Trapped wind) about ways to improve the storage of the energy captured by wind farms. It focused specifically on “compressed air”. The air is hermetically stocked up to be released when needed to provide electricity by turning a generator. The storage of the energy is a key advance in order to minimize the inconvenients of a source of energy that is intermitent, such as wind, and to capture excess electricity that is generated -and wasted- at times when usage is low (e.g., at night). For the main wind power producing areas, the benefits of a way to store, and therefore export the energy, are enormous. In Europe, there is an ongoing project seeking to link the electricity grids to achieve a better match of supply and demand by crossing national borders. In the USA, a group of municipal power companies from Iowa in the American Midwest are building a wind-powered compressed-air plant to take advantage of the windy Great Plains. The

Many people are afraid that wind turbines kill a huge number of birds. Opponents of wind power often use this argument to stop development of wind farms but is it really the true? It is estimated that each year in the USA 57 million birds die in collisions with vehicles 1.25 million in collisions with tall structures (towers, stacks, buildings) more than 97.5 million in collisions with plate glass 4 million to 10 million night-migrating songbirds in collisions with telecommunications towers household cats in the U.S. are estimated to kill 100 million birds each year In comparison each wind turbine kills 0 - 2 birds per year at worst. Global Wind Energy Council (GWEC) figures show that total installed wind energy capacity in 2006 was 74,223 MW Let’s say that every wind turbine has a capacity of 100kW (usually they have more - even over 1500kW), it gives us around 742,230 wind turbines worldwide. Let’s count with the worst scenario - 2 killed birds per turbine per year Win

I enclose an extract of an interesting story by Claudia Blume (full story here), picked up at VOA News (Hong Kong):  Engineers at the University of  Hong Kong and a private renewable energy company have developed a new micro wind turbine that can generate electricity even if wind speeds are as low as two meters per second. Micro wind turbines (Courtesy of VOA News) “We never stop this machine and they never stop because there is always one meter per second wind - 365 days, 24 hours a day, they keep working,” said Lucien Gambarota - the main inventor of the technology.  They are ideal for crowded cities because they can be installed on rooftops and balconies.   Their design is simple: plastic gearwheels, each about 25 centimeters in diameter, are linked to one another and turn, moved by the wind. Groups of gearwheels can be arranged in an array of shapes and sizes. The energy generated by the turbines is stored in a battery, which then powers electrical appliances. The

UK-based Quiet Revolution have done some great work with Vertical Axis Wind Turbines (VAWT) that can be used in urban situations where the wind is not likely to come from one steady direction, but rather from all over the place. Unlike traditional pinwheel-like wind turbines, a VAWT can utilize ...
