The Scottish Wind Assessment Project is an ongoing programme of research which seeks to collate existing studies and commission new research to promote a thorough investigation of the claims made for and against the use of wind-generated energy. It is supported by private donations.
This 'informal white paper' authored by the renewable energy industry and the Electric Reliability Council of Texas addresses the impact of wind's intermittency on the need for the development of comparable capacities of reliable sources that can be called upon when the wind is not blowing. It contains a particularly interesting chart that characterizes different energy sources as 'base load', 'peak load' and 'intermittent' with their associated benefits and drawbacks. Wind is deemed 'intermittent' with the following benefits (no emissions, no fuel costs, stable cost, low operating cost) and drawbacks (not dispatchable, not responsive, transmission needs, low peak value).
Vermonters must decide if it is worth destroying their exquisite mountains for symbolism -- because the giant wind turbines being proposed for the ridgelines won't produce much power.
We cannot lose sight of Vermont's distinctive place in the world with its open spaces and gorgeous vistas. It is up to us to continue the legacy. Real jobs, real lives depend on it.
Almost 70 years ago, Vermonters decided man's hand did not need to be evident everywhere. Remember that spirit now as this state considers allowing wind turbines on ridgelines.
Everyone probably agrees with the fundamental goal of the legislation -- to protect Vermont's fragile environment by increasing the use of clean energy. But before lawmakers rush into mandates, they must ensure the measure doesn't inadvertently harm the economy or the landscape.
According to the study, a further financial and technical strong-arm effort would be required in order to be able to even input the quantity of green electricity planned by the federal government into the German electricity network by the year 2015.
The Kyoto Protocol is due to come into effect this February and we are already more than half way from the signing of the Protocol to the beginning of its first commitment period (and three quarters of the way there since the baseline date of 1990). The world also needs to look beyond Kyoto. Many countries, including the UK, have set themselves ambitious longer term goals, to reduce emissions by 60% or even 75% by 2050. Meanwhile, a number of recent studies – for instance, the climateprediction.net project based on distributed computing and the International Climate Change Taskforce – have stressed the magnitude of the risks and the need for early and effective action. At first sight, the impression given is that everything is more or less on track. The UK Paper says that “our latest projections on the impact that our policies and measures will have on our emissions suggest that the UK remains on course to comfortably achieve its target under the Kyoto Protocol”, though admitting that more needs to be done to meet the 20% reduction in CO2 emissions set as a national goal. The EEA report is more cautious: it acknowledges that the EU is only a third of the way towards meeting its goal (greenhouse gas emissions in 2002 were 2.9% below the 1990 base, as compared with the target of 8 % for the period 2008-2012). However, it suggests that with policy measures in the pipeline and use of the Kyoto mechanisms, the target could be met. What neither report states is that the evidence contained in them could lead to a much more pessimistic conclusion: that the policy measures favoured in the UK and EU have not delivered significant CO2 reductions and are clearly inadequate to the longer term challenge.
If America devoted a mere 1% of its land area to wind turbine farms, it could generate 20% of its electricity from wind, asserts the American Wind Energy Association. And if wishes were horses, beggars would ride. Sadly, equine mirages don’t make sound energy policy. They may generate good sound bites, political polemics and fund-raising appeals. But they don’t generate much electricity.
If you really want to cut energy consumption, reduce pollution, improve public health and protect our environment, it’s time to contact your elected officials, educate them about the lessons of Denmark, Germany and elsewhere, and tell them you want tougher energy efficiency measures instead of wind power plants. Otherwise, in the next few years, you’ll be looking at wind turbines in some of your favorite places, with the knowledge that they’re doing little more than funneling your tax dollars to a few lucky corporations and landowners, and away from better solutions.
Concept for a step-by-step extension of the transmission grid in Germany for the connection and integration of wind turbines onshore and offshore taking into account the production and power station developments and the necessary regulating and reserve power. Introduction: A reasonably priced and reliable electricity supply is an important location factor for the development of an economy. Against this background, it is necessary to investigate the demands placed on the entire system for the generation and transmission of electrical energy, which in future must again be optimised for the integration of the inevitably increasing amount of electricity generated from wind energy. The economic effects resulting from this must also be determined. Maintaining the current level of reliability of supply must be included here as an important boundary condition....
This report presents forecasts of energy supply, demand and prices through 2025.
This plan serves to help guide utilities in their own planning activities by establishing a standard of planning and analysis for utilities.
Wind energy is environmentally harmful and costly to taxpayers. Furthermore, its expansion could adversely affect the nation's electricity transmission system.
Eyesores or clean machines? Environmentalists are split over the giant energy-producing towers popping up in Maryland and other states.

Lessons Learned: E.ON Netz GmbH, the largest grid operator in Germany, reports in its Wind Report 2005, that "Wind energy cannot replace conventional power stations to any significant extent...The more wind power capacity [on] the grid, the lower the percentage of traditional generation it can replace."
....there are too many forms of subsidies and favoritism to determine accurately which energy sources get the best treatment, although some interpretations can be made. In any case, those who argue that their technology should receive more in order to compensate for another technology’s subsidies are being disingenuous. Congressional subsidies in the latest energy bill will only make matters worse.
Key Energy Issues to 2025 The Energy Information Administration (EIA), in preparing model forecasts for its Annual Energy Outlook 2005 (AEO2005), evaluated a wide range of current trends and issues that could have major implications for U.S. energy markets over the 20-year forecast period, from 2005 to 2025. Trends in energy supply and demand are linked with such unpredictable factors as the performance of the U.S. economy overall, advances in technologies related to energy production and consumption, annual changes in weather patterns, and future public policy decisions [see endnote 1 on page 8]. Among the most important issues identified as having the potential to affect the complex behavior of the domestic energy economy, oil prices and natural gas supply were considered to be of particular significance in increasing the uncertainty associated with the AEO2005 reference case projections.
That’s the stunning thing about nuclear power: tiny quantities of raw material can do so much.
