  • A robust transmission system is the cornerstone for large-scale integration of wind power in the United States. Therefore, perhaps the greatest barrier to achieving this goal is building new transmission to connect the large amounts of location-constrained wind resources to the load centers. Another goal-limiting factor is the lack of appropriate market rules across the various interconnections in the US. Furthermore any reversal of policy decisions made at Federal and State levels (e.g. Renewable Portfolio Standards) in support of renewable energy could send the wrong signal to the industry causing uncertainty in the markets, potentially stalling the investments in new wind plants. The reality is that there are five election cycles between now and 2030 so it is important that wind energy related policies are sustained during this period.

     

    Other potential barriers to achieving this 20-by-2030 goal include: a surge in the global demand for wind energy which could limit the supply of turbines in the US; another financial crisis during the next two decades which affects the credit and investment markets; and lastly the lack of skilled work force to operate power systems with high penetration of variable generation.

Scottish Researchers Revolutionize Wind Turbine Engineering With Minor Tweak - 1 views

  • The researchers there have developed a system that is simpler to assemble and manufacture, and laid out their suggestion in a paper (pdf) presented at the 2008 European Wind Energy Conference.


    Till now; the blades of wind turbines have been connected to a generator via a gearbox. Their technology substituted a “C” shaped core generator (initially in a 20 kW prototype) to test to see if by changing the mechanical structure of the generator they could still maintain rigidity and structural integrity while cutting the weight by more than half.


    The design is simply a novel arrangement of the electromagnetically active components: the magnets, steel and copper inside the generator and the copper coils.

    The three companies receiving government grants are:

    * Clipper Windpower: £4.4 million to develop its first prototype 70-metre blade for the Britannia project - the largest wind turbines in the world;
    * Artemis Intelligent Power: £1 million to transfer its existing technology from automotive to wind energy; and
    * Siemens Wind Power UK: £1.1 million to develop the next-generation power converters for its larger offshore turbine.

Do wind installations need one-to-one backup? No. - 0 views

  • Colin Bennett
     
    [Backup for wind] is a very complex issue. Here are my attempts at (hopefully) simple explanations for why the following four statements are, in all four cases, not really accurate. From a wind power perspective, the four statements amount to the same thing.

    STATEMENT: "they (utility) still have to maintain adequate fossil and nuclear capacity for dealing with times without wind."

Offshore Wind Vital to the Future of Europe - 0 views

  • Colin Bennett
     
    According to the European Commission, Europe's power plants are getting older and, combined with growing demand for energy, Europe will need 360 GW of energy from new sources in the next 12 years - this is equal to 50% of current energy capacity in the EU. The EWEA thinks that 40 GW of this energy can be produced by offshore wind.

    In a nation known more for its belching smokestacks, solar water heaters are on nearly every roof in some cities. Manufacturers are eyeing foreign markets, including Southern California.Today, the 40-year-old mother and her family shower every day and wash their dishes with hot water. The stainless steel heater affixed to her red-tiled roof cost about $220.

Obama Administration Provide $3 Billion for Green Energy - 0 views

  • scofider Lp
     
    When Congress was debating an extension of the renewable energy tax credits set to expire at the end of 2008, the loudest argument from the wind and solar industries was that letting the tax credits expire would have a deleterious affect on renewable energy development in the United States. And before the credits expired, Congress passed a short term extension of the renewable energy production and investment tax credits.

Ford's EV Charging System Allows Driving Using Only Renewable Energy | CleanTechies Blog - ... - 0 views

  • Ford Motor Company has developed an intelligent charging system that previews how its production vehicles will interact with the grid. The unnamed system enables all-electric and plug-in hybrid vehicle owners to restrict charging to when electricity prices fall below a certain threshold, or even “when the grid is using only renewable energy such as wind or solar power,” according to Ford.

Europe's onshore and offshore wind energy potential - EEA - 0 views

  • This report provides a Europe-wide resource assessment of onshore and offshore wind potential in a geographically explicit manner. In addition to calculating raw wind resource potential, this study also introduces and quantitatively analyses the environmental and social constraints on wind sector development. Concerns addressed include the noise and visual impact of wind power, as well as the deaths of birds and bats that fly into rotor blades. The report also evaluates the future costs of wind energy production across Europe in order to gauge the potential output at competitive rates.

    Small wind could cost 10 times the cost of residential solar to make the same power.

    The energy yield was measured in an average wind speed of 8.5 mph over the year.

Kenya to build Africa's biggest windfarm as rains fail and hydropower falters | Environment... - 0 views

  • Some 365 giant wind turbines are to be installed in desert around Lake Turkana in northern Kenya – used as a backdrop for the film The Constant Gardener – creating the biggest windfarm on the continent. When complete in 2012, the £533m project will have a capacity of 300MW, a quarter of Kenya's current installed power and one of the highest proportions of wind energy to be fed in a national grid anywhere in the world.
