Fear, Complexity, & Environmental Management in the 21st Century

Complexity_thumb 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.

NYS Dept. of Environmental Conservation letter to the City of Lackawanna re. Environmental Contamination and Birds/Bats

Seqrresp9-2-05_thumb 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.

Wind Power Facility Siting Case Studies: Community Response

National_wind_coordinating_committee_siting_studies_thumb 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.

Man Made Myth: Is Global Warming Mankind's Deadliest Creation- You Decide

Kyotomanmademythiee_thumb 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.

Tom Hewson Analyses Carbon Dioxide Savings of Gray County Wind Farm (KS)

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).

Reduction in Carbon Dioxide Emissions: Estimating the Potential Contribution from Wind Power

Renewable_energy_foundation_thumb 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.

Estimation of real emissions reduction caused by wind

Liik-emissionsreduction_thumb 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. Editor's Note: A worthwhile read in its entirely (attached pdf file). Selected extracts appear below.

Why cement-making produces carbon dioxide

Why_cement_thumb 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 Power: Capacity Factor, Intermittency, and what happens when the wind doesn’t blow?

Rerl_fact_sheet_2a_capacity_factor_thumb 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.
