These
proposals come less than 12 months after proposals to site a 12-turbine
wind farm next to Hinkley Point Nuclear Power Station.
Nuclear
power has been generated at Hinkley for more than 35 years.
But
the decision to decommission the Magnox reactors at Hinkley Point
A indicates an uncertain future for the industry, which still generates
at the Hinkley Point B - a newer pressurised water reactor.
A
windy country
So
on the face of it what could be an easier way of obtaining electricity
than by harnessing the power of the wind?
We
live in a windy country. Wind turbines are relatively cheap to build.
They
are a clean energy source - no polluting carbon dioxide adding to
greenhouse gases.
Certainly
the government sees wind power as playing a significant part in
its commitment to produce 20 percent of the UK's energy needs from
renewable sources by 2020.
With
coal-fired power stations producing huge amounts of carbon dioxide,
and cleaner nuclear stations requiring massive capital outlay and
posing a potential terrorist target in the current political climate,
the case for wind power has never been greater.
Local
electricity generators already have a 'Green Tarriff' which, in
exchange for a premium of around 0.4p per unit, promises to match
consumers' contributions.
These
are then paid into a fund, used to invest in wind farms and solar
panels for schools.
The
cost of producing wind-generated electricity has dropped by more
than 80 percent over the last 20 years, and farmers and landowners
are beginning to see turbines as a source of additional income.
Somerset:
potential for wind farms
Somerset
is a county with a big potential for wind farm development.
Exmoor,
the Quantocks and the Mendips are all high enough and exposed enough
to the prevailing southwesterly winds to meet the minimum criterion
of an average wind speed in excess of 13 MPH throughout the year.
In
fact the turbines can operate with speeds as low as 8 MPH.
They
reach peak efficiency when the mean wind speed is between 30 and
35 MPH. Above about 50 MPH they will shut down.
Not
everyone welcomes the potential increase in wind-generated electricity.
Previous
proposals for wind farms in the West Country have met with considerable
opposition from local residents.
There
are concerns over noise pollution, vibration, television interference
and the visual impact.
The
blades of the largest turbines can be 25 to 40 metres in length
with tower heights of 45 to 80 metres, making an overall height
of 70 to 120 metres - visible for many miles around.
Although
most wind farms are situated well away from population areas, by
their very nature they are visible for many miles around.
Nearby
residents often worry about the effect the siting of these towers
would have on their locality.
Interestingly,
in Denmark, where wind-generated power has been well established
for many years, there have been some 600 official objections to
wind farm schemes on Jutland in the last 6 years.
Of
these only 60 have been found in favour of the complainant. So it
would appear that the case for wind power remains strong there.
Overwhelming
case for diversification
The
case for diversification of UK power production is overwhelming.
Fossil
fuels are becoming increasingly difficult to find and current supplies
lie in often politically sensitive areas.
The
nuclear industry is unlikely to see sufficient investment to put
it at the forefront of UK energy needs.
This
leaves us with renewable forms of energy.
Tidal
barrages and solar power will play their part in the UK's energy
future, but the attraction of wind power is that it is relatively
'lo-tech' and in these windy isles there are many potential sites
for wind farms.
With
the largest turbines now able to meet the needs of as many as 900
homes each we can expect to see applications for turbines and wind
farms rising steadily. The question is whether or not we are prepared
to live with them.
Ros
Coward, writing in the Ecologist in 2001, had no doubts. He said:
"Wind turbines have a beauty and drama, unmatched by any other source
of energy provision.
"Aesthetically,
they can be elegant, with blades resembling bird wings, creating
dramatic shapes against the skyline. They have aspirational, uplifting
and positive symbolism."
In
the next few years we will find out whether the residents of Wincanton,
Hinkley and other windy parts of Somerset agree with those sentiments.
