Government Study Shows U.S. Wind Resources Larger than Previously Estimated | Alison Pr... - 1 views

  •  
    "A new study by the Department of Energy's National Renewable Energy Laboratory (NREL) has revealed that U.S. wind resources are far greater than previously believed. The study, a collaborative project between NREL and AWS Truewind, LLC, of Albany, New York, created resource maps and wind potential tables for 48 states. The recent study is the first comprehensive update of the wind energy potential by state since 1993. The resource maps for the contiguous United States, and separately for each state, show the predicted mean annual wind speeds at 80-meter height. They are derived from 200-meter resolution maps developed by AWS Truewind for the windNavigator system. Areas with annual average wind speeds around 6.5 m/s and greater at 80-meter height are generally considered to have suitable wind resources for wind development"

Antarctica wind farm operational - UPI.com - 0 views

  •  
    "The world's southernmost wind farm, in Antarctica, is now operational. The Ross Island wind farm will supply about 11 percent of the power to New Zealand's Scott Base and the American McMurdo Station. Previously, the two sites relied on diesel-powered generators for electricity. The wind farm will cut diesel consumption by about 463,000 liters a year and reduce carbon dioxide output by 1,370 tons annually, according to New Zealand-based Meridian Energy, the project's developer. The three turbines, each 37 meters tall and 33 meters wide, are generating 330 kilowatts of power."

Sea Power: Germany's First Offshore Wind Park Goes Online - SPIEGEL ONLINE - News - Int... - 0 views

  •  
    Germany's first offshore wind farm has gone online off the North Sea island of Borkum. A year late and 50 million euros over budget, it's still the best hope proponents of green energy have for meeting the country's ambitious emissions reductions targets. Electricity generated by Germany's first offshore wind energy park began streaming into the national network on Wednesday as three wind turbines located 45 kilometers (28 miles) north of the North Sea island of Borkum went online. The three wind turbines are massive. Each towers more than 100 meters (328 feet) above the waves, with blades spanning more than 116 meters. Individually, the wind turbines are capable of generating 5 megawatts of energy per year. The initial trio will be joined later this year by nine more wind turbines. When all 12 go online later this year, the installation is expected to provide enough electricity to power 50,000 homes.

BBC NEWS | Floating wind turbine launched - 0 views

  •  
    The world's first floating wind turbine is to be towed out to sea this weekend. Statoil's Alexandra Beck Gjorv told the BBC the technology, the Hywind, to be put off Norway's coast - "should help move offshore wind farms out of sight". And it could lead to offshore wind farms eventually being located many miles offshore, away from areas where they cause disruption, Ms Gjorv added. This would benefit military radar operations, the shipping industry, fisheries, bird life and tourism.

Global Wind Installations Up 29% in 2008 - Renewable Energy World - 0 views

  •  
    Global wind capacity increased an estimated 27,051 megawatts in 2008, with cumulative installations up almost 29 percent. The United States led in new installations, surpassing Germany to rank first in wind energy cumulative capacity and electricity generation. Nearly 400,000 people are employed by the wind industry worldwide, though this number could slide in the near term due to project financing difficulties, particularly in the United States. A new snapshot of wind energy trends from Worldwatch Institute analyzes data since 1980 and reveals that for the first time last year, wind power represented Europe's leading source of new electric capacity (with 8,877 megawatts added), well ahead of natural gas at 6,939 MW and coal at 763 MW.

The cost of wind, the price of wind, the value of wind - 0 views

  •  
    Jerome a Paris has an excellent (and long) article at TOD about the economics of wind power - The cost of wind, the price of wind, the value of wind. I'd like to try to clear some of the confusion that surrounds the economics of wind power, as it is often fed and used by the opponents of wind to dismiss it. As I noted recently, even the basic economics of energy markets are often wilfully misunderstood by commentators, so it's worth going in more detail through concepts like levelised cost and marginal cost, and identify how different electricity producers have different impacts on electricity (market) prices (which may or may not be reflected in retail prices) and have different externalities. Value for society of a generation source may also include other items that are harder to acount in purely monetary terms (and/or whose very value may be disputed), such as the long term risk of depletion of the fuel, or energy security issues, such as dependency on unstable and/or unfriendly foreign countries or vulnerable infrastructure.
