When wind turbines are placed in a wind-farm, they are anchored to the ground by
concrete foundations, these foundations are impervious to water, so, instead of rainwater
seeping through the ground it remains on the surface. What many people do not realise
though, is that all the turbines are connected by cables to an interconnector which
then links the electricity produced to the national grid. These cables are normally
put underground, however in many cases digging out the ground for them can disturb
(or even destroy) the natural field drainage, preventing rainwater from seeping into
the ground. The consequences of this is that the water will drain to the nearest
river possibly increasing the river flow, and in some cases may cause an increase
in flooding in some areas.
If the wind farm had not existed, then some of this water would have been absorbed
by the soil, draining into underground streams and aquifers.
WIND - WEEDS
Wind-Weeds are those giant monstrosities which are springing up everywhere these
days, serving no useful purpose, destroying views, Inhibiting tourists from visiting,
damaging human lives. They may also be implicated in increasing flooding (see below).
These structures are difficult to eradicate, especially as they are protected by
governments world-wide. Although they are deemed to be protecting the environment
by producing carbon-free power, they require expensive fossil-fuel power stations
as permanent back up when the wind either fails to blow enough or is too strong for
the turbines to spin effectively.
Most of the wind which reaches the UK comes from the west or south west over the
Atlantic Ocean. This wind picks up large amounts of moisture. When the wind reaches
the UK, it increases in height when it passes over hills and mountains, then becomes
cooler - unable to hold some of this moisture and releases it as rain. (One reason
why places like Greenock and Manchester are among the wettest in the UK). Obstructions
like buildings also cause the wind height to increase., In some cases by 10 times
the height of the obstruction..
What happens though, if the obstructions are 450 feet high wind towers? Does the
wind ignore them and just pass through, or does it treat these obstructions like
buildings and raise over these towers by up to 450 feet, or even more than 450 feet,
loosing even more moisture by rain. This would explain why some areas are experiencing
greater flooding than ever before and other areas are becoming drier.
The only way to test this though is by using wind-tunnels, which does not seem to
have been done. Wind-tunnels have been used for optimum siting of wind towers, which
show that if the towers are all at the same height then the wind will decrease by
over 30% travelling downwind through the towers. If the towers are situated on a
hill then the wind decrease is much less.
