Off with all their heads

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

Estonia halts expansion of ‘expensive’ windmills

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.”

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.
