Why Wind Won't Work
Author: Boone, Jon
Between the: (1) uncertainty about what power sources wind energy would replace or avoid from minute to minute, (2) the operational inefficiencies inherent in switching conventional power sources off and on to accommodate wind’s continuously changing intensity, and (3) the emissions created in the construction and operation of the wind power facilities, actual measurement of emissions offsets due to wind installations is difficult to calculate accurately, and the results would vary from grid to grid. Moreover, consumers of electricity will . . .

Evidence to the House of Lords Economic Affairs Committee inquiry into ‘The Economics of Renewable Energy’
Author: Bratby, Philip
10 My evidence is mainly concerned with wind power stations for generating electricity. This is because these form the major component of all major country’s future renewable energy policies. …
11 The most important consideration for the future electricity supply has to be security of that supply. …
12 Security of supply implies firm generation capacity with a margin above the peak (winter) demand. The firm generation is supplied by baseload power stations (such as nuclear) and despatchable (controlled by the grid) power (such as coal, gas . . .

Amplitude Modulation of Wind Turbine Noise
Author: Bowdler, Dick
A Review of the Evidence
“Conclusions: It seems probable that there are two distinct mechanisms in operation to create amplitude modulation. The first is swish which is a function of the observer’s position relative to one turbine. The second is thump which is due to turbine blades passing through uneven air velocities as they rotate. In the second case the uneven air may be due to interaction of other turbines, excessive wind shear or topography. These two . . .

Plywood wind turbine blades?
Author: Oike, Yuki
These wind turbines are placed in Izu peninsula of Shizuoka prefecture, which is about 120 km from Tokyo.
Two turbines were destroyed by lightning in April.
A member of Higasi-izu town assembly took these photos.
He said there was plywood in the blades (which can be see in the photos). In general it is said that wind turbine blades are made of fiber-reinforced polymer. But in fact these are made with plywood inside.
The turbines were made in Germany or Denmark (not Japan).
[The blades . . .

Windenergy: the whole truth [Windmolens en wat meestal verzwegen wordt]
Author: Halkema, J.A.
‘In order to make a fair judgment on the possible usefulness of windturbines for the production of “clean electricity” (energy generated by wind, as a major source of green renewable energy), one should only use arguments based on reality. Biased statements based on the concerns of windturbines makers or on political motivations ought to be refrained, as they are suspicious beforehand.
‘Apart from being rational, the arguments used in a debate should also be underpinned by numbers. And it speaks for . . .

Safety Regulations for Operators and Technicians
Author: Vestas Wind Systems
“Do not stay within a radius of 400m (1300ft) from the turbine unless it is necessary. If you have to inspect an operating turbine from the ground, do not stay under the rotor plane but observe the rotor from the front.”
“In case of a fire during an uncontrolled operation, do under no circumstances approach the turbine. Evacuate and rope off the turbine in a radius of minimum 400m (1300ft).”

Estimate: €900,000+ to dismantle and dispose of one turbine
Author: Malafosse, J.
Montpellier, January 29, 2008
Sirs,
Following the consultation that you asked for, here is the estimate that we propose for the dismantling and demolition of wind turbines in the commune of Saint Etienne de Lugdares.
The dismantling and demolition require the presence on site of:
One 700-tonne crane and two 50-tonne cranes.
A Copex CVM 500 metal press and shredder.
A team of five people for 30 working days for unbolting, blow-torching, and shredding the metal parts.
Class II disposal of the nonrecyclable parts of the turbine. . . .
