Last week's
announcement by National Grid of the preferred location for the substation to
serve wind farms in Wales
brings a long-running dispute to the surface once again. But like many Welsh political arguments, it
is an argument which seems to generate more heat than light.
Many of those I saw
interviewed by the BBC were refreshingly honest - they concentrated on issues
such as the view from their homes and villages and the effect on property
values as the basis of their opposition.
These are issues to which most of us can relate; but ultimately,
electricity generation, and the infrastructure to support that, have to go
somewhere, and local concerns have always to be balanced with wider needs.
We need
electricity, and we need to generate it somehow. We cannot all assume that the electricity we
want and need will be generated ‘somewhere else’. If we are going to build wind farms in Wales then the
infrastructure to connect them to the grid has to go somewhere. Not building substations is simply not an
option.
That in turn brings
us right back to two underlying questions.
The first is
whether and to what extent onshore wind has a role in the energy mix, and the second
is the subsequent question of where it should be sited.
The second of those
is the easier of the two to answer - the best location is always going to be
the one where the presence and speed of wind is most consistent. And whether we might choose it to be thus or
not, Welsh uplands are ideal from that perspective.
The first question
is rather harder. It is an issue on
which opinion is seriously divided, and raises a number of issues.
Some opponents of
on-shore wind don't accept the need to reduce emissions, and reject the idea
that anthropogenic climate change is a real phenomenon. This is, at least, an honest position to
adopt. It may fly in the face of
majority scientific opinion, but majority scientific opinion hasn't always been
proved right. If emissions are not a
problem, we can simply go on using gas, oil, and even coal.
However, the
consequences of rejecting the majority view if it's right are much worse than
the consequences of accepting the majority view if it’s wrong. That balancing of risks and consequences
would be enough to convince me that we should act, even if I wasn't convinced
that the scientific majority was right.
And once we decide to act to reduce emissions, the fact that, as of
today, on-shore wind is the most proven and readily available source of
renewable energy is an inescapable fact.
"The benefits will flow elsewhere", we are told. It’s true of course. But it's also true of many other things that
happen in Wales,
whether relating to energy generation or not.
It's an argument (and one I’d entirely accept) for changing the economic
model under which we exploit a resource, but it's not an argument for
non-exploitation as such. I want Wales to have
control over its own infrastructure, and to be able to make a decent profit
from those things of which we can produce a surplus. But I also want there to be some
infrastructure and surpluses for us to bring under our own control.
“It's exploiting Welsh resources for the benefit of England." Again,
possibly true, but over-simplistic. Exploitation
doesn't recognise, or stop at, borders.
If turbines were built on some of the more suitable locations in England
(whether as well as, or instead of, is irrelevant in this context), that
exploitative (if it is indeed such) relationship between users of electricity and those living close
to the points at which it is generated would still be the same; it would merely
have become internalised within a different set of human-defined borders. (In any event, is either the wind or the landscape really 'owned' by those who happen to live nearby, or is it more widely 'owned' by us all?)
"They wouldn't be built without the
subsidies." Again, it's true that the subsidy regime
encourages renewable rather than fossil fuel electricity generation. That's exactly what it is intended to do, in
order to reduce emissions from energy generation. But it's also true that other forms of
generation are effectively "subsidised" by being able to externalise
some of their costs. Not all subsidies
appear in our electricity bills, but that doesn’t mean that they don’t exist.
But perhaps the
favourite counter argument is the one about "wind
farms are useless". It is an
issue which I have posted on before a number of times. If it were true, then it would indeed be
something of a killer argument against both turbines and the supporting
infrastructure.
It is, though, a claim
which is often based on selective use of facts, some interesting ‘interpretations’
of facts, and sometimes even simplistic axiomatic assertion. Whilst a sensible policy wouldn’t go above
around 15% - 20% wind in the overall generation mix, the argument that it is
completely useless doesn’t stand up to examination.
The argument about
whether the sub-station should go on the proposed location will no doubt
continue – but it has to go somewhere, and the best form of opposition would be
to come up with a more acceptable location rather than simply oppose its
construction.
