Offshore wind energy system combines sea water and wind to create electricity

Megan Treacy for TreeHugger:  We've seen our share of interesting wind power designs, but often the technology can't come anywhere close to matching what the traditional horizontal axis wind turbines can do. There's a reason that when we think of wind energy, we think of giant masts with rotating blades and it's because that design is incredibly effective -- just look at Scotland and other areas around the world that now get a majority of their electricity needs from wind power.

The design isn't without its flaws; those rotating blades do pose a hazard to birds and bats and the cost of manufacturing and installing all of those giant parts can be expensive. When it comes to offshore wind power in the U.S., that has been a major roadblock. The energy generation potential is huge, but so is the cost.

An energy start-up company called Accio Energy -- yes, a Harry Potter reference -- thinks it has a solution to that problem, one that will generate as much if not more energy from offshore wind than a traditional wind turbine, but at half the cost. There are no moving parts, instead Accio's technology consists of large permeable panels on masts that let the ocean winds blow right through.  Cont'd...

Government support for offshore wind creates massive economic opportunity for Britain

RenewableUK says today's Government announcement of the next round of competitive auctions to support offshore wind will provide a boost for British industry.

New York set for offshore wind after environmental review

Daniel J. Graeber fro UPI:  Areas off the New York coast will be open for offshore wind energy bidders, but some area is reserved because of ecological concerns, the U.S. government said.

The U.S. Interior Department, in coordination with its Bureau of Ocean Energy Management, said it would open 79,350 acres off the coast of New York up for a commercial wind energy lease sale. About 1,780 acres was removed because of environmental concerns associated with a subsea feature known as the Cholera Bank.

"In a comment letter, the National Marine Fisheries Service identified the Cholera Bank feature as a sensitive habitat to be avoided for the placement of structures," an Interior Department stated read. "As a result of this removal, the revised lease area will be approximately two percent smaller than the lease area considered in the proposed sale notice."  Cont'd...

Europe's offshore wind industry booming as costs fall

The Guardian:  On a sunny October morning, our boat passes the run-down relicts of Liverpool’s maritime past and heads down the river Mersey and into the Irish Sea. As we steam offshore, I see in the distance a cluster of tall structures that soon reveal themselves to be towers of a wind turbine array. Arriving at the windfarm, six miles offshore, the turbines rise as high as 650ft, taller than the tallest church in the world. Each of the turbines’ three shiny metallic rotor blades is nearly 300ft long.

“A single rotation of an eight-megawatt turbine will cover the daily electricity consumption of an average British household,” says Benj Sykes, vice president of Dong Energy Wind Power, the company that is constructing and co-owns this wind project, as the boat rocks in five-foot swells.  Cont'd...

Labor Leaders Tour America's First Offshore Wind Project, See More Jobs Over Horizon

Labor leaders from across New England, New York, and along the Atlantic coast today toured Deepwater Wind's Block Island Wind Farm off the coast of Rhode Island, getting a first-hand look at America's first offshore wind turbines and hearing how the project has already created over 300 local jobs. Sen. Jack Reed (R-DI) also joined the tour, organized by Rhode Island Building and Construction Trades Council, BlueGreen Alliance, and National Wildlife Federation.

Think Wind Power Is Cheap Now? Wait Until 2030

Katherine Tweed for GreenTechMedia:  In many parts of the world, wind power is cheap. That is particularly true in the U.S., where onshore wind already rivals the cost of natural gas in some regions.

But wind power will likely get even cheaper, according to new research from Lawrence Berkeley National Laboratory published in Nature Energy, with contributions from the National Renewable Energy Laboratory, University of Massachusetts, and participants in the International Energy Agency Wind Technology Collaboration Program.

The study surveyed more than 160 wind experts across the globe. Many had deep expertise in very specific regions, but the overall findings were similar: The cost of wind will continue to come down through 2030.

There are significant variations in the current costs for wind by region, but researchers "found a considerable amount of agreement” in overall reductions as a percentage of that total cost, said lead author Ryan Wiser, a senior scientist at Berkeley Lab.  Cont'd...

Wind power fiercer than expected, study finds

Phys.org:  University of Delaware researchers report in a new study that offshore wind may be more powerful, yet more turbulent than expected in the North Eastern United States.

The findings, published in a paper in the Journal of Geophysical Research: Atmospheres, could have important implications for the future development of offshore wind farms in the U.S., including the assessment of how much wind power can be produced, what type of turbines should be used, how many turbines should be installed and the spacing between each.

The study, led by Cristina Archer at UD and Brian Colle at Stony Brook University, analyzed historical data from 2003-2011 at the Cape Wind tower located near the center of Nantucket Sound off the coast of Martha's Vineyard, Massachusetts, and collected complementary data at the same location in 2013-2014.

Co-authors on the paper, titled "On the predominance of unstable atmospheric conditions in the marine boundary layer offshore of the U.S. northeastern coast," include UD professors Dana Veron and Fabrice Veron, and Matthew Sienkiewicz from Stony Brook.

The paper's main finding is that atmospheric conditions around Cape Wind are predominantly turbulent, or unstable, which is in stark contrast to prevailing data from European offshore wind farms in the Baltic Sea and the North Sea. European studies of offshore wind document that atmospheric conditions there are predominantly neutral— meaning neither too windy nor too still, but somewhere in the middle, with unstable wind conditions occurring only 20 percent of the time.  Cont'd...
