CARBON TRADING FIASCO by someone who should know – T.L. Cardwell


To the Editor,
First I should clarify. I spent 25 years in the Electricity Commission of NSW working, commissioning and operating the various power units. My last was the 4 X 350 MW Munmorah Power Stations near Newcastle . I would be pleased to supply you any information you may require.
The Morning Bulletin.(Rockhampton)

I have sat by for a number of years frustrated at
the rubbish being put forth about carbon dioxide
emissions, thermal coal fired power stations and
renewable energy and the ridiculous Emissions
Trading Scheme.

Frustration at the lies told (particularly during the
election) about global pollution. Using Power Station
cooling towers for an example. The condensation
coming from those cooling towers is as pure as
that that comes out of any kettle.

Frustration about the so-called incorrectly named
man-made ‘carbon emissions’ which of course is
Carbon Dioxide emissions and what it is supposedly
doing to our planet.

Frustration about the lies told about renewable
energy and the deliberate distortion of renewable
energy and its ability to replace fossil fuel energy
generation. And frustration at the ridiculous carbon
credit programme which is beyond comprehension.

And further frustration at some members of the
public who have not got a clue about thermal
Power Stations or Renewable Energy. Quoting
ridiculous figures about something they clearly
have little or no knowledge of.

First coal fired power stations do NOT send 60 to
70% of the energy up the chimney. The boilers of
modern power station are 96% efficient and the
exhaust heat is captured by the economisers and
reheaters that heat the air and water before entering
the boilers.

The very slight amount exiting the stack is moist
as in condensation and CO2. There is virtually no
fly ash because this is removed by the precipitators
or bagging plant that are 99.98% efficient. The 4%
lost is heat through boiler wall convection.

Coal-fired Power Stations are highly efficient with
very little heat loss and can generate a massive
amount of energy for our needs. They can generate
power at efficiency of less than 10,000 b.t.u. per
kilowatt and cost-wise that is very low.

The percentage cost of mining and freight is
very low. The total cost of fuel is 8% of total
generation cost and does NOT constitute a
major production cost.

As for being laughed out of the country, China
is building multitudes of coal-fired power stations
because they are the most efficient for bulk power

We have, like, the USA , coal-fired power
stations because we HAVE the raw materials
and are VERY fortunate to have them. Believe
me no one is laughing at Australia – exactly
the reverse, they are very envious of our raw
materials and independence.

The major percentage of power in Europe and
U.K. is nuclear because they don’t have the
coal supply for the future.

Yes it would be very nice to have clean, quiet,
cheap energy in bulk supply. Everyone agrees
that it would be ideal. You don’t have to be a
genius to work that out. But there is only one
problem—It doesn’t exist.

Yes – there are wind and solar generators being
built all over the world but they only add a small
amount to the overall power demand.

The maximum size wind generator is 3 Megawatts,
which can rarely be attained on a continuous basis
because it requires substantial forces of wind. And
for the same reason only generate when there is
sufficient wind to drive them. This of course depends
where they are located but usually they only run for
45% -65% of the time, mostly well below maximum
capacity. They cannot be relied on for a ‘base load’
because they are too variable. And they certainly
could not be used for load control.

The peak load demand for electricity in Australia
is approximately 50,000 Megawatts and only small
part of this comes from the Snowy Hydro Electric
System (the ultimate power Generation) because
it is only available when water is there from snow
melt or rain. And yes, they can pump it back but it
costs to do that. (Long Story).

Tasmania is very fortunate in that they have mostly
hydro-electric generation because of their high
amounts of snow and rainfall. They also have wind
generators (located in the roaring forties) but that is
only a small amount of total power generated.

Based on an average generating output of 1.5 megawatts
(of unreliable power) you would require over 33,300 wind generators.

As for solar power generation much research has
been done over the decades and there are two types.

Solar thermal generation and Solar Electric generation
but in each case they cannot generate large amounts
of electricity.

Any clean, cheap energy is obviously welcomed
but they would NEVER have the capability of
replacing Thermal Power Generation. So get your
heads out of the clouds, do some basic mathematics
and look at the facts, – not going off with the fairies
(or some would say the extreme greenies.)

We are all greenies in one form or another and
care very much about our planet. The difference
is most of us are realistic. Not in some idyllic utopia
where everything can be made perfect by standing
around holding a banner and being a general pain
in the backside.

Here are some facts that will show how ridiculous
this financial madness is that the government is
following. Do the simple maths and see for

According to the ‘believers’ the CO2 in air has
risen from .034% to .038% in air over the last
50 years.

To put the percentage of Carbon Dioxide in air in
a clearer perspective;

If you had a room  3.7 x 3.7  x 2.1 metres
the area carbon dioxide would
occupy in that room would be .25 x .25 x ..17m
or the size of a large packet of cereal.

Australia emits 1% of the world’s total carbon
Dioxide and the government wants to reduce
this by 20%t or reduce emissions by 0.2 % of
the world’s total CO2 emissions.

What effect will this have on existing CO2 levels?

By their own figures they state the CO2 in air has
risen from .034% to .038% in 50 years.

Assuming this is correct, the world CO2 has increased in 50 years by …004%.

Per year that is .004 divided by 50 = …00008%. (Getting confusing -but stay with me).

Of that because we only contribute 1% our emissions would cause CO2 to rise .00008 divided by 100 = …0000008%.

Of that 1%, we supposedly emit, the governments
wants to reduce it by 20% which is 1/5th of .0000008 = ..00000016% effect per year they would have on
the world CO2 emissions based on their own figures.

That would equate to an area in the same room, as
the size of a small pin.

For that they have gone crazy with the ridiculous trading schemes, Solar and Roofing Installations, Clean Coal Technology. Renewable Energy, etc, etc.

How ridiculous it that?

The cost to the general public and industry will be enormous. Cripple and even closing some smaller businesses.
