BREWER - As wind power begins to blow into Maine, state regulators on Wednesday considered its potential to squeeze increasingly expensive - and less environmentally friendly - fossil fuels out of the region's energy mix.
On Thursday the seven states decided to proceed with this plan, which stands to reduce greenhouse gas emissions from their power plants by 10 percent by 2020.
In reality, nobody has a fog what will happen. This is Virtualia, not the UK. During the last year, global warming has been predicted to lead to wetter winters, drier winters, another ice age, blazing-hot Mediterranean summers killing thousands, greater biodiversity and less biodiversity
A group of Northeast states has postponed the announcement of a landmark agreement to limit greenhouse gas emissions from power plants after Governor Mitt Romney raised objections to the pact late last week, two government sources familiar with the agreement said yesterday.
TALLINN - Wind power has fallen out of Estonia’s favor in recent months, with the Economy Ministry deciding to limit support to wind-power producers and Parliament adopting amendments to the energy law that will give preference to other forms of renewable energy. Einari Kisel, head of the Ministry of Economy and Communications’ energy department, puts it bluntly: “We do not want to have too many wind mills,” he says. “The price of wind energy is expensive. The unstable production causes additional costs to other producers.”
And for that matter, who believes that the complex system of our atmosphere behaves in such a simple and predictable way that if we reduce one component, carbon dioxide, we will therefore reliably reduce temperature? CO2 is not like an accelerator on a car. It’s not linear (and by the way, neither is a car accelerator.) And furthermore, who believes that the climate can be stabilized when it has never been stable throughout the earth’s history? We can only entertain such an idea if we don’t really understand what a complex system is. We’re like the blonde who returned the scarf because it was too tight. We don’t get it.
September 2, 2005 City of Lackawanna Planning and Development Board Room 311, City Hall 714 Ridge Road Lackawanna, NY 14218 Attn: Joseph G. Geyer Re: Steel Winds Wind Farm Route 5, Former Bethlehem Steels works Lackawanna, NY Dear Mr. Geyer; The New York Sate Department of Environmental Conservation (DEC) staff have performed an initial review of the information and material provided with the City of Lackawanna’s SEQR Notice of Coordinated Review and Declaration of Intent to Act as Lead agency. These materials include the Application for Site Plan Approval and Certain Area variances to Authorize Construction and Operation of a Wind Energy Facility on a Portion of the Former Bethlehem Steel Works Site in Lackawanna, New York (the Application), and the Analysis of Environmental Impacts pursuant to SEQR (The EA). Please be advised the DEC does not object to the City of Lackawanna assuming the role of lead agency, but the DEC does reserve the right to comment on this action if a positive determination is made. As indicated in the following text of this letter, DEC staff have concerns for the potential impacts of certain aspects of this project. Our comments and concerns are listed below under the appropriate topic.
BBC Research & Consulting's 2005 report for the National Wind Coordinating Committee that studies 9 wind plant sitings in an effort to identify circumstances that distinguish welcomed projects from projects that were not accepted by communities.
Billions of dollars are being spent to stop so-called manmade global warming. Already we have been told "it is a bigger threat to manking than international terrorism", with runaway warming, rises in sea levels and increases in the number of floods, hurricanes, droughts and tropical diseases predicted. Faced with this, a pragmatic technological society might decide it would get best value for money by modernising existing inefficient coal-fired stations, building nuclear power stations and efficient transport. But instead, we have poured sources into renewables.
Deep in the Allegheny Mountains of West Virginia sits a giant coal-fired power plant aptly named Mount Storm - a 1,600-megawatt goliath that just a few years ago ranked second in the nation in toxic mercury emissions.
The Beacon Hill Institute at Suffolk University has studied the Cape Wind proposal in considerable detail, and offers the following comments on the Draft Environmental Impact Statement (DEIS) Reference file no. NAE-2004-338-
I was asked to review the prefiled testimony and exhibits of Matthew Rubin for the East Haven Windfarm and to provide an independent opinion regarding the claimed environmental benefits, estimated benefit values, project footprint and noise impacts and general wind project economic issues.
Given its location, Gray County would have displaced mostly NGCC and some oil fired generation. Using the average 2003 NGCC heatrate for the sub-powerpool (7,478 Btu/kWh) and the average CO2 content of natural gas (116 #CO2/MMBtu), the project may have displaced only 158,000 tons of CO2 in 2003 (0.00207% of 2003 US estimated emissions according to the USDOE report entitled Emissions of Greenhouse Gases in the United States, 2003 (issued December 13, 2004). (Note in 2002, the output was less and it would have displaced only 140,000 tons).
In the UK, the parallel objective is to generate 10% of the UK’s electricity from renewable sources by 2010. Renewable electricity has become synonymous with CO2 reduction. However, the relationship between renewables and CO2 reduction in the power generation sector does not appear to have been examined in detail, and the likelihood, scale, and cost of emissions abatement from renewables is very poorly understood. The purpose of this report is to analyse a wide range of technical literature that questions whether the renewables policy can achieve its goals of emissions reduction and power generation. To some, renewable energy has the simple and unanalysed virtue of being “green”. However, the reality of this quality is dependent on practical issues relating to electricity supply. ......In conclusion, it seems reasonable to ask why wind-power is the beneficiary of such extensive support if it not only fails to achieve the CO2 reductions required, but also causes cost increases in back-up, maintenance and transmission, while at the same time discouraging investment in clean, firm generation.
The aim is to show that the fuel economy and emissions reduction in the power systems consisting mainly of thermal power plants are not proportional with the electricity production of wind turbines. Participation of thermal power plants in the compensation of fluctuating production of windmills eliminates major part of the expected positive effect of wind energy. A method for calculation of real fuel economy and emissions reduction is described and a calculation example basing on Estonian and Danish data is given.

Unfortunately, there is a major flaw in all this current "fixative" thinking. Simply put, no matter how strong any Senate mandate, the technology needed to stabilize global atmospheric levels of CO2 does not exist. This crucial fact, noted in science journals, is woefully ignored.
In line with the American, Russian and numerous other non-European governments, Australia is not submitting to globally planned greenhouse gas controls while third world competitors, such as China, India and South Africa, remain exempt from the strictures of the Kyoto Protocol. Contemporary Australian experts with years of serious research on global warming argue against the Australian government signing Kyoto.
Climate changes such as global warming may be due to changes in the sun rather than to the release of greenhouse gases on Earth.
Cement manufacturing is the third largest cause of man-made carbon dioxide emissions. While fossil fuel combustion and deforestation each produce significantly more carbon dioxide (CO2), cement-making is responsible for approximately 2.5% of total worldwide emissions from industrial sources (energy plus manufacturing sectors).
Wind turbines convert the kinetic energy in moving air into rotational energy, which in turn is converted to electricity. Since wind speeds vary from month to month and second to second, the amount of electricity wind can make varies constantly. Sometimes a wind turbine will make no power at all. This variability does affect the value of the wind power……Editor’s Note: This ‘fact sheet’ is, on the whole, a comparatively fair report. The definitions provided for capacity factor, efficiency, reliability, dispatchability, and availability are useful. Its discussion of back-up generation, marginal emissions and Germany & Denmark, however, is disingenuous as is, to a lesser degree, its discussion of capacity factor and availability. IWA's comments (updated October '06) on these issues follow selected extracts from the 'fact sheet' below.
