Synopsis: Energy: Energy forms: Renewable energy: Wind power:

One of the solutions to cut down on polluting fuels is the use of wind energy. But the rise in wind farms has unintended its own effects.

Air traffic control systems are being interfered with, both offshore and across moors and hills. The movement of the turbine blades creates, essentially,

In places such as Scotland, where the projections for wind farms are amongst the densest in the world,

As the need for wind power increases, a solution will have to be found. Jet-rocket hybrideventually, mankind will see long distance travel-London to Sydney, for example-taking place outside the Earth's atmosphere.

but it has year-round trade winds to run wind turbines. The Barbados government is also looking into harnessing the energy of the tides as well as introducing ocean thermal energy conversion (OTEC) a technology

Whether it a new wind farm in Iowa an energy efficiency retrofit in Massachusetts, or a utility-scale solar array in Nevada, these projects require American ingenuity and labor.

if Congress reinstates critical tax policies such as the wind industry production tax credit (PTC) and several energy efficiency tax incentives.

#GE Makes A Wind turbine Especially For Japan Generous solar power feed in tariffs have driven a boom in installations in the last year

and solar cools off wind power might find a new opening in the Japanese market. This is the speculation from industry players in a new Japan Times article looking at wind power in Japan.

GE sure seems to be positioning itself for opportunities in Japan introducing what it calls the. 85-103 wind turbine for Japan.

That right Japan gets its own wind turbine. GE says the 2. 85-103 comes with enhanced tower engineered for Japanese environmental conditions including seismic and extreme wind events as required by Japanese construction and building codes.

GE explains: GE 2. 85-103 wind turbine is engineered specifically for Japanese environmental conditions and is able to withstand higher turbulence areas typhoon class extreme wind speeds

and lightning beyond the current IEC standard. The 2. 85-103 for Japan includes the Japanese requirements for lightning protection across all Japanese regions

Japan installed wind power capacity inched up steadily during the 0s with 200 to 300 megawatts going in each year.

and wind power to charge their batteries or produce hydrogen to power fuel cells. Moreover, as Ie previously mentioned, driving on electricity is compared cheaper to driving on oil.

Furthermore, America largest source of new electrical capacity in 2012 came from wind power, lifting the total U s. wind capacity to more than 60 gigawatts.

and size issues by combining the best traditional wind technologies with a unique wind delivery system that produces more efficient and powerful wind generation machines.

Ultimately combining technologies will allow us to achieve the necessary power generation capacities to transform wind energy into a reliable baseload power source.

This could be the beginning of transforming wind power into the baseload power source that coal has been since the early 1900s.

for the first time in wind industry history three turbines may run in series in a single tower to produce more energy.

Its patented INVELOX wind funnel technology brings wind energy production to ground level. By capturing, concentrating, and accelerating wind energy, ultimately reducing costs,

while solving major problems that have plagued the industry, including low turbine reliability, intermittency issues, and environmental impacts.

Sheerwind is poised to turn wind power into a major power source for the globe. For more see:

#Wind turbine Trees Generate Renewable energy for Urban Settings French entrepreneur Jérôme Michaud-Larivière decided to do something about that.

Applications abound Another application for MUPROD work is the manufacturing of large but lightweight parts for wind power.

and wind power accounts for a growing portion of the capacity now being proposed, which further complicates how it should be treated.

And wind power reached record output levels last year producing a massive 25.2 GW and accounting for 39 percent of the electricity supply on a single day in December The unprecedented growth of solar PV in particular has been fueled in large part by policies that incentivize clean energy.

#Altaeros Energies floating wind turbine churns out electricity and Wi-fi This floating turbine, developed by Altaeros Energies could someday travel to every remote corner of the globe.

Video) Think of these floating turbines as the wind farms of the future and you won be that far off.

Another application could be in wind turbines, where films of water on the blades can, if they freeze in cold weather, lead to catastrophic failures.

but proponents of a hydrogen economy say that it could be produced in vast quantities from water using excess electricity from wind turbines and solar plants.

Long-term, large-scale storage of wind energy could best be achieved by simply storing compressed hydrogen underground. Where methanol-hydrogen systems might have a role,

#Wind energy reaches greater heights Wind turbines across the globe are being made taller to capture more energy from the stronger winds that blow at greater heights.

and Alexander Slocum, the Pappalardo Professor of Mechanical engineering at MIT is developing a novel system that adapts a traditional pipe-making technology to churn out wind turbines on location,

at wind farms, making taller towers more economically feasible. Keystone system is a modification of spiral welding,

because the trees slow down the wind near the ground you can see a 50 percent increase in energy capture for the same wind turbine.

Solving transport problems The Keystone system value lies in skirting wind turbine transportation constraints that have plagued the industry for years.

Towers are made in segments to be shipped to wind farms for assembly. But theye restricted to diameters of about 14 feet

Smith explains. ut there no way to weld together a tower in a factory that 20 feet in diameter and ship it to the wind farm.

while conducting an independent study on wind energy issues with Slocum. Running a consulting company for machine design after graduating from MIT

Smith was vetting startups and technologies in wind energy, and other industries, for investors. As wind energy picked up steam about five years ago, venture capitalists soon funded Smith, Slocum,

and other wind energy experts to study opportunities for cost savings in large, onshore wind turbines. The team looked, for instance,

at developing advanced drivetrain controls and rotor designs. ut out of that study we spotted tower transport as one of the biggest bottlenecks holding back the industry,

Now, the company is working with the Danish wind turbine manufacturer Vestas Wind Systems, and other turbine makers, to plan out full-scale production,

In Maine, for example, there only a small percentage of the state where wind power is economically feasible today,

In the Midwest, wind energy has reached already grid-parity, undercutting even today low-cost natural gas but in areas like New england and the Southeast,

taller towers are needed to reach the strong winds that make wind energy economically feasible. nce youe at the heights wee looking at,

when it comes to wind power. Founded by alumni Ben Glass 08 SM 10 and Adam Rein MBA 10 Altaeros has developed the world s first commercial airborne wind turbine

Instead its purpose is to bring wind power to remote off-grid areas where towers aren t practically or economically feasible.

It s really about expanding wind energy to all those places on the fringes where it doesn t really work today

and expanding the amount of wind power that s able to be deployed globally Rein says. Aerostat innovationmuch of the BAT s innovation lies in its complete autonomy Glass says.

Harboring an interest in wind turbine design and knowing that traditional towers could never reach high-altitude winds he designed the BAT in his free time receiving technical guidance from Institute Professor Sheila Widnall and other faculty.

For their first power-producing prototype they bought a small reliable wind turbine rotor and cut off some metal in the back that was dead weight

For example the wind industry grew from a $500 million industry to a $15 billion industry in five years.

#The Quest To Harness Wind energy At 2, 000 Feet To be more precise it's a stabilizing fin part of a tube-shaped robotic airship designed to tap the power of high-altitude winds.

The blade tips of today's tallest conventional wind turbine installed at a test center in Denmark this year stretch to 720 feet.

While typical wind turbines of similar scale require a large crew and several days to install the BAT is ready to fly

and a combination of permafrost and snowed-in roads complicates the installation of standard wind turbines.

We're not trying to replace wind turbines Rein says. We're trying to expand wind energy to places where it doesn't work today.

In 2010 when Rein and cofounder Ben Glass were fresh out of MIT and building their first balsa-wood prototype high-altitude wind energy was still largely unknown.

Altaeros has grown now to a 10-person operation and a half dozen or so competitors are racing to market with roughly a dozen more working on designs.

A megawatt-class BAT anchored 10 miles off the coast would need significantly smaller foundations than traditional offshore wind systems

and the future of wind energy it would seem floats in our fingertips. Altaeros has a handful of competitors.

#An All-Liquid Battery For Storing Solar And Wind energy You could call it a rainy-day fund.

A team of MIT researchers has built an all-liquid battery prototype that's designed to store excess energy from solar and wind power plants.

When Bearings Inside Wind turbines Will Fail Engineers from the University of Sheffield have developed a novel technique to predict

when bearings inside wind turbines will fail which could make wind energy cheaper. The method, published in the journal Proceedings of the Royal Society A and developed by Mechanical engineering research student Wenqu Chen,

uses ultrasonic waves to measure the load transmitted through a ball bearing in a wind turbine. The stress on wind turbine is recorded

and then engineers can forecast its remaining service life. When a bearing is subject to a load

its thickness is reduced by a very small amount due to elastic deformation, and the speed of sound is affected by the stress level in the material.

which are a common problem in wind turbines. By removing the risk of a loss of production and the need for unplanned maintenance,

it can help to reduce the cost of wind energy and make it much more economically competitive."

such as solar and wind power, but to get enough generating capacity from these sources will take too long,

when excess power reduces the real-time price of power to less than zero sometimes associated with excessive wind generation conditions.

#First Offshore wind farm In U s. Under Construction In July, American offshore wind developer, Deepwater Wind, installed the first foundation for

what is expected to be the first offshore wind farm in the United states. The project will be located three miles southeast of Block island, Rhode island.

the Block island Wind farm is expected to come online in 2016. Deepwater Wind, the developer, is also planning two larger offshore projects along the Atlantic coast,

200 gigawatts (GW) of developable offshore wind potential, compared to its estimate of 11,000 GW of onshore wind potential.

Wind resources are classified on a scale of zero to seven based on their power density, and more than 66%of offshore wind in the United states is in wind power class six or seven.

In addition, offshore wind turbines are built to take advantage of the more consistent wind speeds present over the ocean,

allowing higher utilization rates for offshore generation capacity when compared with similarly sized onshore wind turbines.

However, offshore wind is significantly more expensive to build and maintain than onshore wind. Although there are currently no operating offshore wind projects in the United states

offshore wind turbine technology has grown steadily in Europe, and, to a lesser extent, in Asia. As of 2014, Europe accounted for 90%of the estimated 8. 8 GW of installed global offshore wind turbine capacity.

Offshore wind power development in Europe began in 1991 when the first offshore farm was installed off the coast of Denmark,

although the industry had little growth from that point until the 2000s. In the United states, developers have proposed building nearly 4. 9 GW of offshore wind capacity off the coasts of nine different states,

but some challenges remain even for projects that have advanced through key regulatory and market milestones.

For example Cape Wind, a 486-MW project proposed in 2001, faced significant challenges and litigation that halted its progress.

In 2014, National grid and Eversource Energy terminated the power purchase agreements with Cape Wind because of missed project development deadlines.

Other projects such as the Virginia Offshore wind Technology Advancement Project and Fisherman Energy Wind of New jersey have faced development hurdles despite making significant progress in project development.

Compared with Western europe, the current leader in offshore wind energy the United states is estimated to have more abundant and favorable onshore wind resources,

which are located largely in areas with low population density. So far, the high cost of domestic offshore wind projects has made them economically unattractive,

despite the availability of federal tax incentives and state policies to promote use of renewable energy.

Building and maintaining offshore wind technology is compared expensive with onshore wind projects because of challenges such as transporting equipment and workers to the sites

'As well as tourism, the elevator could also be used for wind energy generation and communications. The mastermind behind the project is inventor Dr Brendan Quine.

if wind energy is to swell by 40 percent during this time, high-voltage, long distance transmission will need to enlarge by 9 percent.

The American Wind energy Association says that up to 60,000 megawatts of new wind energy development is planned possible

allowing the transmission operator known as ERCOT to nearly double its use of wind energy. There, nearly $15 billion has been invested to generate about 19,500 megawatts of wind energy.

Meantime, it says that transmission operators in the Midwest and the Southwest are enacting similar policies.

In standard turbine design, wind energy is used to turn the unit's rotors, which then converts this type of power into electricity through powering machinery

and accounts for a problem faced by any system reliant on wind energy--the natural element's variability.

Described as the on-demand generation of electricity from stored wind energy, the patent application details a mechanism in

The variable nature of wind may interfere with on-demand generation of electricity from wind energy.

For example, fluctuations in wind speed may hamper the adequate production of electricity from wind power during periods of peak demand,

In turn, such variability may limit the ability to incorporate large amounts of wind power into a grid system.

#Wind turbines Power Liquid-air Energy storage One startup energy company is looking to reinvent not only wind energy, but also energy storage.

Keuka Energy recently launched a 125-kilowatt prototype vessel that uses its novel floating wind turbine design paired with liquid-air energy storage to create a steady source of electricity.

Unlike traditional wind turbines, which have three blades and a central gearbox, Keuka turbine is a pinwheel of aluminum blades that sits atop a floating V-shape platform containing liquid air.

The Florida-based company claims that its wind turbine design allows for larger turbines that could produce far more electricity.

The world largest single offshore wind turbine is currently about 6 megawatts; Keuka says its full-size turbines could produce at least double that amount.

The company also says its wind turbine design is more cost effective thanks to elimination of the gear box and the use of lightweight aluminum blades that cost less than 10 percent the price of traditional composite blades.
