because attachments may take time to receive and may be difficult for

1. George Monbiot, author of much hype about global warming, has
discovered the limitations of micro turbines and accuses their promoters
of hype (APPENDIX A). Perhaps he will eventually get the point about
large-scale wind generation of electricity too.
2. Described as "the world's longest underwater pipeline", the 1200 km
Langeled pipeline opened at the end of September. It is to bring gas
from Norway equivalent to one fifth of winter peak fuel demand. It lands
at Easington in East Yorkshire (not Easington, County Durham). (Ceefax
page 108, 30-9-06.) The markets showed a rapid response, especially as
the weather has been mild and gas storage capacity is 96% full. There
was a glut of gas in UK and a fall to negative wholesale prices (minus
5p per therm), so traders had to pay to get rid of it! (Ceefax 110,
3-10-06)
3. From news@all-energy 72 and 73, (APPENDIX B). UK transmission
companies (gas & electric) fear their 4.5 billion pound spending
allowance might not be enough to fix new wind farms to the national
grid. A more intelligent distribution system is sought, to take variable
renewable power.
4. Dermot Finnigan (news214.2) writes again after being
taken to hospital and surviving his dangerous hunger strike.
5. Pre-inquiry meetings for the Beauly - Denny line are under way this
month. The relevant matters to be considered in the inquiries themselves
are quite inclusive, according to the list in the Minute of Appointment
of the Technical Adviser, Giles Scott, which says: "The scope of his
report will include: need for the line and associated substations, power
system operation and security, route of the line, different options for
the line including undergrounding, EMF levels and possible health risks,
network resilience to storms, proximity of the line to trees and
buildings, construction and decommissioning, and access and maintenance
during operation.
6. More news from Poland (see also news210.7) and an appeal to sign
their petition are at APPENDIX D.
7. National Grid choose preferred partner for 500 million pound
contract for grid reinforcement in western England and Wales (APPENDIX
E).
8. Cilfrew Residents' Association tells us (APPENDIX F) of a new area
of difficulty with NG "bullying tactics", with gas pipelines. Hitherto
NG had evoked that reaction with electric power lines but since the
merger with Transco former electricity staff are now dealing with gas
pipelines. It is a pity, since at the time of the Yorkshire 400 kV line
local landowners contrasted NG with the co-operative approach from BP
over its ethanol pipeline in the same locality.

APPENDIX A Monbiot on small-scale wind turbines.
New Scientist magazine, 30 September 2006, issue 2571
Small-scale renewable power - low-wattage thinking?
George Monbiot
TO PREVENT global temperatures rising by 2 °C above pre-industrial
levels, the
rich nations must cut their carbon emissions by 90 per cent by 2030.
In seeking to work out how this might be done, I have made many
surprising findings,
but none has shocked me as much as the discovery that renewable
micro-generation - whereby people generate their own electricity with
devices on
their houses or in their gardens - has been grossly over-hyped. Those
who say we
can produce all the electricity we need and heat our homes from
renewable sources
have harmed the campaign to stop climate chaos, by sowing complacency
and
misdirecting our efforts.
Here's an example of how misleading the rhetoric over micro-generation
can be.
Last year, the environmental architect Bill Dunster, who designed the
famous
BedZed zero-carbon development outside London, published a brochure
claiming
that "up to half of your annual electric needs can be met by a near
silent micro wind
turbine". The turbine he specified has a diameter of 1.75 metres.
A few months later Building for a Future magazine, which supports
renewable
energy, published an analysis of micro wind machines. In winds of 4
metres per
second - higher than average for most of the UK - a 1.75-metre turbine
produces
about 5 per cent of an average household's annual electricity. To
provide the 50 per
cent Dunster advertises, you would need a machine 4 metres in diameter,
which
would rip the side off your house.
?In almost all circumstances, micro wind turbines are a waste of time
and money?
What's more, turbulence makes wind generators even less efficient, and
to avoid it
you must place them at least 11 metres above any obstacle within 100
metres. On
most houses, this means constructing a minor hazard to aircraft. And the
higher the
pole, the more likely you are to inflict serious damage on your house.
In almost all
circumstances, micro wind turbines are a waste of time and money.
What about micro solar power? In his book Half Gone (Portobello Books,
2006),
Jeremy Leggett, who is chief executive of the solar energy company
Solarcentury,
claims that "even in the cloudy UK, more electricity than the nation
currently uses
could be generated by putting photovoltaic roof tiles on all suitable
roofs". This is a
big claim, so you would expect it to come from a good source - a peer-
reviewed
journal, perhaps. But the reference Leggett gives is "Solar Energy:
brilliantly simple,
BP pamphlet, available on UK petrol forecourts".
The estimate is contradicted by the European consultancy firm Future
Energy
Solutions, formerly the Energy Technology Support Unit, which calculated
that if
solar electricity could somehow achieve an efficiency of 12 to 15 per
cent at all point
s of the compass, the "maximum practicable resource" in the UK in 2025
would be
266 terawatt-hours per year. Total annual electricity demand in the UK
is currently
407 TWh.
Leggett's claim is even more misleading than this suggests. For a start,
solar panels
facing north produce less power than solar panels facing south.
Furthermore,
seeking to generate all our electricity this way would be staggeringly
and pointlessly
expensive; there are far better ways of spending the money. The
International Energy
Agency's MARKAL model puts the cost of saving carbon using solar
electricity in
2020 at between £2200 and £3300 a tonne. Its estimate for onshore macro
wind
power, by contrast, ranges between a saving of £40 and a cost of £130 a
tonne. A
third problem is that solar electricity supply is poorly matched to
demand. In the UK,
demand peaks on winter evenings. Even if we could produce 407 TWh a year
from
solar panels on our roofs, most of it would be wasted.
What about the argument from some campaigners that even though
micro-generators can make only a small contribution, they still wake
people up to
green issues? It seems more likely these devices will have the opposite
effect, as
their owners discover how badly they have been ripped off and their
neighbours are
driven insane by the constant yawing and stalling of the ill-sited
windmill.
What's the alternative? Far from replacing the national grid with more
localised
power supplies, as the Green MEP Caroline Lucas suggests, we should be
greatly
expanding it to carry renewable energy from places where it is most
abundant. This
means, above all, a massive investment in offshore wind farms. A recent
UK
government report suggests England and Wales have a potential offshore
wind
resource of 3200 TWh. High-voltage direct current cables would allow us
to make
use of a larger area of the continental shelf. This means we can
generate more
electricity more reliably, avoid spoiling the view from the land and
keep out of birds'
migration routes.
The electricity system cannot be run on wind alone. But surely it's
clear that building
giant offshore windmills is a far better use of our time and money than
putting
mini-turbines in places where they will generate more anger than power.

APPENDIX B From news@all-energy 72 of early October 2006
(and, further below, from issue 73)
3.GRID, TRANSMISSION, ETC
3.1.£4.5bn to invest in UK's energy
The owners of Britain's gas and electricity networks will have £4.5
billion to spend on meeting the
country's energy needs over the next five years, £2.5 billion less than
they had requested....
transmission companies fear that it will not be enough to fix new wind
farms to the national grid...
http://business.timesonline.co.uk/article/0,,9078-2374546,00.html
From issue 73:
3.5.Making electricity distribution systems more intelligent
Imperial College leads a three-year, £4m project to make the electricity
distribution system more intelligent, so alternative sources of power
can be integrated without overloading the ageing distribution system.
4.14.Put windfarms near cities
More wind farms should be sited near to population centres in order to
cut power losses and minimise the impact of pylons on the countryside.
8.3.A third industrial revolution?
'Europe is a huge continent of renewable energy, but it's disparate.
Hydrogen can store all these different forms of renewable energy. Smart
power grids, currently being tested in the US' Silicon Valley, could
then be used to distribute energy. The grids can be used like the
Internet. There's an opportunity here to create a third industrial
revolution' - Jeremy Rifkin, founder and president of the Foundation on
Economic Trends in the US

APPENDIX C Letter from Dermot Finnigan after surviving ordeal.
Dear Mr Chairman and Chief Executive.
You now have the report that proves your line is in trespass and yet you
refuse to release it
The suppression of the evidence by a company worth £450billion to deny a
family their entitlement is both cruel and callous.
Maybe you could explain your decision.
I was taken to hospital last Tuesday night and released on Thursday
evening. I have recovered over the weekend and will be in London again
this week to make myself available to you in the hope you can bring
yourself to meet with me and resolve this crippling dispute.
Yours Faithfully
Dermot Finnigan

APPENDIX D Message from Poland
Dear Friends!
if you believe that children have a right to safe life,
if you believe that people have a right to protection of their immediate
environment,
if you believe that big companies shouldn’t break the law and
carry out their investments by
force protected by armed people,
if you respect such values like honesty and justice,
if you don’t want to anyone to be allowed to put seventy-metre
2x400kV and 2x200kV pylons near your home overnight without consulting
you, pylons blinking with red lights, pylons with 26 wires making noise
heard within the range of 500 metres, being a threat to your
children’s lives, if you want the law to be changed so that it
prevents such things happening, help us, please!

APPENDIX E. Press release - AMEC JV appointed preferred bidder for
£500m National Grid
contract
London, United Kingdom (24 October 2006)
A joint-venture between AMEC, the international
project management and services company, Babcock
International and Mott MacDonald, has been
appointed by National Grid as the preferred
partner for the West Overhead Lines and Cable
Alliance, which will carry out the upgrade of
overhead power lines and underground cables
across the western half of England and all of Wales over the next five
years.
The contract will be worth £500 million (AMEC's
share: £237.5 million) over an initial five-year
period, after which the contract may be extended for a further five
years.
As part of National Grid's expenditure of up to
£2.8billion on alliances to improve the
electricity transmission network, the joint
venture's work will enable new infrastructure
such as wind farms and other new electricity
generation plant to be connected to the grid and
will cover enhancement and replacement of
existing assets to ensure the safe and reliable
operation of the electricity network.
"We are delighted to be extending our strong
relationship with National Grid and look forward
to working in partnership to deliver an upgraded
transmission network that will bring significant
benefits to our customer, the public and the UK
economy," said Samir Brikho, chief executive of
AMEC. "This major electricity alliance contract,
similar to our alliance with National Grid for
gas networks, underlines AMEC's expertise in
providing long-term asset support for the energy infrastructure sector."
AMEC and its partners are now finalising
contractual and operational details and expect
the contract to be signed in early 2007.

APPENDIX F Trouble with NG over gas pipelines.
I understand your site is regarding power lines but we are facing
exactly the same struggles with the NG plc industrial pipeline running
through Wales into Gloucestershire in England. The same bully boy
tactics, the same people. We have rotten Councils who are conniving
votes to get this project through in spite of major unrest along the
route of this massive pipeline. The Forest of Dean and Hereford Planning
Authorities have recently thrown out NG's application for stations along
the route and the Resident's Association of Cilfrew are awaiting a
Judges decision on leave to apply for Judicial Review. Could you please
highlight our plight along with your own as we are facing the same
people and the same carnage of our beloved countryside with no choice
whatever, in spite of the UK Government ratifying the Aarhus Convention
in February 2005.
The three main "pillars" (as some people sometimes refer to them) of the
Aarhus convention Agreement are outlined at:
Thank you,
Linda Ware, Secretary
Cilfrew Resident's Association
Member of Safe Haven Network
