Dear All, Sept 12, 2007
Wind energy has some serious drawbacks that seem to have been=20
overlooked, the most serious being--
1) COST: How will increases in the cost of wind be absorbed into the =
cost structure ?
2) MERCURY: Using wind to generate electrical power could result in =
less=20
usage of coal and thus less Hg in the environment. With less Hg in =
the=20
environment, Loons might become low in Hg, ride higher in the water =
and=20
consequently become top-heavy and have a tendency to flip sideways =
and=20
gargle at critical points in the call.
3) SEA BIRDS: Using wind to generate electrical power could result =
in=20
less usage of oil and less oiling of birds at sea. This biocontrol =
helps=20
to avoid overcrowding of sea bird colonies so a decrease in oil =
spills=20
could have serious consequences.
4) TREES: Using wind to generate electrical power could result in =
lower=20
concentrations of low-level Ozone, acid-rain and consequently lead =
to=20
less effective biocontrol of trees. And consequently, for example,=20
Spruce trees in the Annapolis Valley might begin to live longer than =
80=20
years, posing dangerous navigation hazards to flying birds as =
compared=20
to a low cover of Heath, Sedge and Alder
5) AIR: Using wind to generate electrical power could result in a =
lower=20
incidence of smog alerts, respiratory ailments and presumably health =
problems in birds or other air-breathing wildlife. A decrease in the =
incidence of smog could increase life expectancy, cause overcrowding =
and=20
increase the demand for electricity and nesting sites.
6) WIND: Using wind to generate electrical power is likely to slow =
the=20
wind down so that it doesn't get there on time, causing air pockets. =
The=20
recent Westjet air-pocket incident, far from the nearest wind farm,=20
shows how dangerous this effect can be.
Yours truly, Dave Webster, Kentville
