Dung Power: A New Kind of Battery Farming

Note from the National Enquirer - I wanted this to go on our Climate Action Brisbane blog but that is the "old" blogger and no longer seems to be available (or at the moment atleast). I'll need to get the admin to convert that to the new blogger.




Article from whypandas.spaces.live.com blog.

Who’d have guessed it, the future of the planet may soon be assured by a giant pile of cow droppings. An English agricultural college is generating its own electricity by tapping into the vast amounts of methane produced by cattle dung. Students at the Walford and North Shropshire College collect the dried out faeces its herd of cows deposits each day then pump the liqufied poo into a digester which in turn powers a generator. They are now producing all the electricity they need to run a new, environmentally-friendly college building. "Everything that comes out of the back end of an animal goes in,” Adrian Joynt, farm manager of the College’s new £2.7m Harris Centre told the BBC this week. "We actually get enough energy to supply the farm's electricity for a year."

The idea is doubly efficient in environmental terms. The methane cattle produce is a major contributor to global warming. Dairy cows can belch 106 to 132 gallons of methane gas a day, 200 times more than a human. (It’s reckoned that the UK’s 2.2 million cattle account for around 7 per cent of our greenhouse gases although that’s nothing compared to New Zealand, whose 40 million sheep and 10 million cows produce 43 per cent of its emissions.) By processing it this way the amount of methane let loose into the atmosphere is drastically reduced, say Friends of the Earth. All this gives the term battery farming a whole new meaning. Presumably, it also means that at this particular building the s*** is actually powering the fan.

Article from UK Sun newspaper.

BOOKIES are offering odds of just 25-1 on a Great White SHARK being caught off British shores next year.

Experts believe climate change may mean UK waters are soon feeding spots for the Jaws monsters.

Totesport’s Damian Walker said: “As the sea around the UK is getting warmer many of the Great White’s prey have been moving into UK waters.”

The bookie firm is offering a series of global warming wagers — with 4-1 odds that next year is the hottest on record. And it is 50-1 that the Thames Barrier will be breached in a decade. You can even back a month of next year to be hottest or wettest — with July 8-11 favourite to be the hottest.

But it is 7-4 there will be no White Christmas in London before 2011. Mr Walker said: “We hope these odds generate plenty of interest.”

The Tote will give half the bets’ profits to charity Friends of the Earth.

Article from Birmingham Post (Business).

As the cost of fossil fuels continues to soar, stocks continue to deplete, and damage to the environment persists, the issue of developing a sustainable fuel resource remains at the top of the environmental agenda.

The combustion of fossil fuels is the biggest contributing factor to the growing threat of climate change and sustainable fuel is needed to alleviate the pressure.

Temperatures in central England have risen by one degree Celsius since 1960. Although it could be argued that climate change has been a natural and frequently occurring phenomenon over the history of Earth, scientists and politicians largely agree that releasing harmful 'greenhouse gases' traps heat within the atmosphere and therefore causes global warming.

Man-made greenhouse gases pose a greater threat to the environment due to the huge increase in their production since the Industrial Revolution.

The gases considered most dangerous, and those that could be reduced by changing the ways in which people source their energy, are carbon dioxide, methane and nitrous oxide which have increased respectively by 31 per cent, 150 per cent and 16 per cent since mid-18th century.

Looking at fresh ways to power the future

As the cost of fossil fuels continues to soar, stocks continue to deplete, and damage to the environment persists, the issue of developing a sustainable fuel resource remains at the top of the environmental agenda.

The combustion of fossil fuels is the biggest contributing factor to the growing threat of climate change and sustainable fuel is needed to alleviate the pressure.

Carbon dioxide is the result of burning fossil fuels to produce electricity and during fuel consumption for transport.

International targets to reduce levels of carbon dioxide by a third by 2020 and half by 2050 have been set. However there are parties that want to see changes take place more rapidly.

A recent plea from Friends of the Earth, backed by 34 of the Midlands' MPs from all political parties, for the Government to take action within four years to reverse global warming demonstrates the urgency of looking at alternate energy options.

The necessity to develop alternate fuel is becoming widely accepted and implemented into international, European and national law and is in the long term interests of energy companies who will stand to benefit by investing in sustainable energy forms.

In a survey, nearly 30 per cent of the world's top companies did not comment on the impact of climate change-related issues on their business.

This ignorance is likely to become unacceptable given that that 95 per cent of voters in a recent poll agreed that the Government needs to legislate to force organisations to reduce their carbon footprint.

The British economy is dependent on fossil fuels. For those who dismiss the environmental factors as the need to change energy sources, the fact that these are non-renewable resources that will exhaust one day cannot be over-looked for long.

By 2050 a world is envisaged where people fill up their cars with electricity, biofuels or hydrogen from multi-fuel stations and where hydrogen fuel cells are routinely used to provide heat and power in homes.

Vehicle emissions are second only in emitting harmful carbon dioxide output to the energy industry itself, accounting for 25 per cent of emissions.

With some alternative fuels becoming cheaper than petrol and diesel, and with tax incentives to use these alternatives, converting to environmentally sustainable fuels really can be a viable undertaking.

Other popular sustainable alternatives to petrol include:


  • Ethanol, methanol and butanol, which are all sourced from fermented plant matter.
  • Liquid Petroleum Gas (or LPG) is a naturally derived heavy gas produced from petroleum during processing and stored as a liquid.
  • Compressed Natural Gas (or CNG) is similar to LPG n Biofuel or biodiesel is made from oil extracts sourced directly from vegetables and plants, or from recycled household vegetable oil.


The electricity consumption in the average EU household has been increasing at about two per year for the past few years.

Although significant improvements in energy efficiency have been achieved in home appliances and lighting 90 per cent rely on fossil fuels for their power.

Solar energy is an example of a sustainable fuel that could be put to use in the UK.

A number of companies and new developments are converting to solar power. Solar energy is immediately replaceable, with no direct damage to the environment as it utilises rather than depletes the sun's energy.

Solar power is progressing rapidly.

Birmingham is already showing efforts to adapt to sustainable fuel.

In 2005 Birmingham City Council received an award from the Ashden Trust for installing solar panels at the Alexander Stadium. At the time, it was the largest array of solar panels in Britain.

A partnership between the city, Worcester-based npower and Solarcentury enabled the energy saving system to be implemented. Solar energy provides electricity for the stadium and sports centre as well as selling excess to the national grid.

Matt Brown, deputy facility manager at the Alexander Stadium, said: "The slanted roof captures low angle sunlight, particularly valuable during winter months.

"The facility produces enough electricity to power 26 three bedroom homes every year. The emission savings of this revolutionary power supply equate to preventing 79,883kg of carbon dioxide to date entering our atmosphere. It would take 60 trees 100 years to absorb this much carbon. "

The UK's geographical position makes it one of the best locations for utilising renewable energy. The first wind farm was established in November 1991.

By March 2004 there were 1,043 wind turbines in operation at 84 sites around the UK, providing 649.4 MW or 0.3-0.4 per cent of the UK's electricity supply.

There are also two offshore wind farms at Blyth Offshore (4MW) and North Hoyle (60 MW). A massive one is also planned for the Thames Estuary.

They were very expensive when they were first introduced but initial costs have fallen considerably, making it a more affordable option.

The British Wind Energy Association points out that there is now primary legislation to ensure that ten per cent of our renewable energy - three per cent of our electricity - will come from wind power by 2010 and 15 per cent by 2015.

Wind has the potential to supply a third of the world's electricity by 2050, according to a report by umbrella group the Global Wind Energy Council and Greenpeace International.

The report concludes that the development of wind power is key in the fight against dangerous climate change.

It offers a blueprint for wind to supply 16.5 per cent of global electricity by 2020 - saving 1.5 billion tonnes of carbon dioxide emissions - and 34 per cent by 2050.

Sven Teske, energy expert at Greenpeace International said: "The required carbon dioxide reduction can only be achieved if wind power plays a major role in the power sector."

Attention is also turning back to coal because of its widespread availability and stable price. But the industry has had to clean up its act in recent years.

Politicians and industry experts hope the development of 'clean coal technology' will make the fuel environmentally acceptable.

New technologies are under development towards a zero emissions future.

The technological progression within the coal industry to ensure the environmental challenge is met works around three core elements:


  • Eliminating emissions of pollutants such as particulates, oxides of sulphur and nitrogen
  • Increasing thermal efficiency to reduce carbon dioxide and other emissions
  • Eliminating carbon dioxide emissions


Coal also has the potential to produce an essential source of hydrogen for completely clean future energy systems including transport.

Currently accounting for just 0.43 per cent of the UK's energy, biomass is seen as one route to meeting targets for the reductions of carbon dioxide emissions and increased use of renewable energy.

Biomass is any plant material which can be used as a fuel, such as energy crops, wood, agricultural waste and vegetable oils. It can be burned directly to generate power, or treated to create gas or oils to be used as fuel.

An environmental project in Stafford, has produced the first crop of miscanthus - a perennial grass - harvested to provide fuel for the UK's first bio-energy plant.

Bob Talbott, founder and company chairman, said: "We have been heavily involved with the design of a two and a half megawatt generator which will utilise the miscanthus crops and eventually provide enough electricity to power around two thousand local homes."

The use of miscanthus will save carbon dioxide emissions and the plant's residue, in the form of ash, will be used as fertiliser by farms to promote miscanthus growth.

A number of businesses have already adopted a sustainable energy 'green' workplace including Innocent, a company derived on a solely 'green' basis.

It was founded in 1998 with a mission to provide healthy drinks in a sustainable fashion and the use of recycled plastic in bottles - having electricity supplied by sustainable power is helping them to achieve this goal.

Richard Reed, co-founder, said: "We've always run Innocent on green electricity, it's important to us to make Innocent drinks a truly sustainable company. We also really like the way that Good Energy works. They're independent and ethical and the way they treat their customers, suppliers and environment is really important to them."

Mac OS X Leopard vs. Windows Vista

As a keen Mac person (and just-as-much an anti-Microsoft person), was delighted to come across this ezine site (see http://roughlydrafted.com/ RD/RDM/ 5C98C705-ACCC-45AF-AA07-BB1E3D216387.html). The discussion are logical and well-argued in their anti-Microsoft positioning and any comments against what the author has said are followed up in an equally logical and well-argued response.

I will quote a portion from the 5th part in the series:




The Difference of the Challenges Faced


Apple's existing Mac OS X Tiger has been in ongoing use by millions of grandmas, creative professionals, school kids, and molecular biologists for nearly two years.

Leopard doesn't face a huge list of security flaws, legacy baggage, and core architectural problems that desperately need to be fixed; its just icing on a cake that already tastes pretty good.

Vista, on the other hand, faces significant challenges. Microsoft's existing Windows XP is the root of the most expensive destruction caused by any operating system ever.

Severely FUBAR


Windows deficiencies have spawned a third party market for antivirus and security tools that drains away many billions of dollars of direct repair costs, and untold billions of lost productivity every year.

Vista is challenged with solving poor engineering decisions made in past decades: some were the product of earlier technology limitations, but others were the result of sloppy and irresponsible development, a fact that even Microsoft publicly recognizes.

In addition to the problems Microsoft has created, the company also struggles with problems caused by bad third party development for which the company has no control. Developers who skirted Microsoft's public APIs and refuse to let go of deprecated legacy have forced the company to support a mess of old technology that impedes progress and folds excessive complexity into Microsoft's code base.

Out of Control


If Microsoft were entirely in control of its own destiny, it could quickly banish support for legacy hardware and decisively move developers into the future by laying out clean new APIs and simply killing off the outdated, arcane ways of doing things that drag down Windows development like millions of tiny anchors tearing up the ocean floor as the ship from Redmond struggles to push forward.

As a smaller, nimbler company that isn’t hamstrung by foot dragging hardware partners, Apple can plot its own future, and has solved its legacy issues by enforcing the meaning of deprecated.

Apple isn't escaping a plague of viruses and spyware because of its smaller installed base, but rather because of the simpler, cleaner design of its software, a luxury afforded by the company's power to move decisively and cast off the unnecessary baggage and boat anchors of past legacy.

This gives Apple another advantage with Leopard over Vista: Leopard can quickly adopt and exploit new features though its tight integration with a known, limited set of hardware precisely because it only runs on Apple's Macs.

Microsoft's Vista not only has to support an incredible variety of existing hardware, but is also obligated to support a lot of poorly written software as well.

This has worked in Microsoft's favor in the past, as its legacy support served to complicate rivals’ efforts to compete against Windows in the PC operating system market. Against Apple however, it puts Microsoft at a significant disadvantage, particularly in the consumer markets Apple is targeting.

Legacy development issues also play into the technology that shapes the elegance Leopard and Vista can offer.

Opposed to nuclear power industry in Australia

To: umpner@pmc.gov.au

To whom it may concern,

I oppose nuclear power in Australia, especially when we have so many better, safer, cheaper, more sustainable methods of generating power for Australians.

Nuclear power stations take a tremendous amount of time and money to build. They consume enormous amounts of water. They elevate the risk of nuclear contamination and they heighten the risk of terrorism using nuclear contaminents (why would the Australian government be so behind the nuclear industry given this when they joined in a war against terrorism?). We have no idea of the cost of decommissioning nuclear power plants nor the effort involved. The uranium supplies in the world will not support a world-wide nuclear power industry for very long. And lastly, the money that will go into this could build lots of alternative energy processing plants, employ a lot of people, develop industries Australia could export and leave surplus money to improve the public transport and increase energy efficiency in our society.

The British Sustainable Development Commission rejected Nuclear as a solution to climate change (http://www.sd-commission.org.uk/pages/060306.html) back in March 2006 and the story was featured in New Scientist. Why would Australia run it's own surveys and then push forward with a nuclear power industry?

The nuclear choice does not make sense.

Yours sincerely,

Brooke

Submissions from other people


From: Hugh Spencer (Dr. Hugh Spencer Director of Research - Cape Tribulation Tropical Research Station)

Response to the:

Uranium Mining, Processing and Nuclear Energy Review (UMPNER) Taskforce,

Draft Report


To whom it may concern,

Advocating the use of nuclear energy for powering Australia, is a sublimelyfoolish act.

The terms of reference for the Uranium Mining, Processing and NuclearEnergy Review (UMPNER) Taskforce, specifically exclude considerations ofother issues such as environmental impacts, energy conservation, long termdecommissioning and treat the adoption of the nuclear fuel cycle inAustralia as a fait accomplit.

What we are seeing is a 'Business as Usual' scenario - which completelyignores the fact that it is mankind's galloping consumption of energy(coupled with unfettered population growth) that is causing the rapidlyescalating climatic effects that we call 'Global Warming'.

The report also flies in the face of many of the recommendations of the2004 White paper 'Securing Australia's Energy Future'.

especially.... "ensure Australia uses energy wisely".

Our first and primary act, is to drastically throttle down national energyuse. This requires concerted and properly informed government action. ThereWILL be impact on the economy (the God-head of our consumer culture), butif we don't act sensibly - the changes wrought by climate change willensure that there won't be much of an economy in the future that we wouldrecognise.

As Al Gore (An Inconvenient Truth) says - "Tackling Climate Change is themoral equivalent to War". - and as such, the Government of the day musttake leadership.


  1. The Howard government must re-visit and widen the very narrow set ofreferences given to this commission, references which do not allow theconsideration of possibly or even probably much better, cheaper, safer,more sustainable and more effective energy sources like wind, solar,biomass, wave and geothermal (the latter two can reliably provide baseloads). These options should be considered in this or an equal commissionand their costs and development potentials should be compared before anycommitment to nuclear energy is made.

  2. There is no estimation of the costs of decommissioning nuclear plantsand the total costs (including inflation) for the long term safe storageand safeguarding of nuclear waste for the entire time that it radiatesdangerous levels of radioactivity and I ask this commission to includethose costs into the estimated consumer costs of nuclear power. Thesecosts can be extremely high and can negate financial benefits,

  3. There is no mechanism discussed whereby covering the costs ofdecommissioning or effects of accidents CAN BE GUARANTEED into the future.With the escalating costs of fossill fuels (and the enormous energy costsinvolved in de- commissioning) there is NO guarantee, that at the end of a25 year service life, that resources WOULD be available at all!

  4. I ask that this commission provide an estimate of known uranium reserves(in Australia and worldwide), their relative richness and how long theycould supply the world at present technology and usage and at the expectedworldwide increased usage (with and without an Australian nuclear industryas envisioned by the draft report).

  5. This commission must consider the worldwide political implicationsof going nuclear at a time when we want Iran and South Korea to stop theirnuclear programs and when we would not want most other countries to gonuclear.

  6. The commission must consider that after over 60 years of nuclear industrythere does not appear to be a single safe long term deposit for highlyradioactive waste anywhere in the world and no widely accepted evidencethat there will ever be one. In no case should we start using nuclearenergy before safe long term storage of waste can be assured for thehundreds or thousands of years they will be radioactive for.

John Hill and Jo Wynter

10th December, 2006.

To whom it may concern:

We are writing to express our sincere and extreme concern about the precipitous rush to expand uranium mining and perhaps build nuclear reactors in Australia.

Firstly, we would like to protest at the brief amount of time allowed for submissions to be made on the Report.

Timing the submissions to be due by December 12th, during the lead-up to Christmas, seems guaranteed to limit proper discussion and consideration of these very important issues - we can only hope that this was not deliberate.

We strongly request that more time be allowed for submissions and that proper public debates of the Report's findings be conducted about the process and the many points it raises.

If an extension is not given and more public participation encouraged, we believe the whole process will be brought into disrepute.

Not having had time to study your Draft Report properly to make a detailed and thorough response, we have limited ourselves to raising a some issues we feel have not been considered carefully enough in the Report.

A number of statements in the Report are, at best, very misleading. On several key points it is difficult to believe such statements by "experts" could have been made in good faith. For example, the Report (on p. 7) says:

"Similarly, other environmental impacts of the nuclear fuel cycle including air pollution emissions, land use and water use are either comparable to or significantly lower than conventional fossil fuels and renewables."

This is simply not true!


  • Air pollution emissions: It is true that (barring accidents) nuclear plants normally produce far less greenhouse gases and other air pollutants than fossil fuel plants. But it is not true to claim they produce less than "renewables."

    There is significant production of air pollution and greenhouse gases in the construction of nuclear stations - more, according to most studies than is produced in during the production and construction of wind, wave and the various solar systems including photovoltaics. Additionally, during the production of electricity renewables produce significantly less of these contaminants than nuclear plants because they are not reliant on the on-going mining and refining of uranium. Also, of course, with "renewables," there is zero possibility of a repeat of the massive radioactive contamination of the atmosphere that occurred after the Chernobyl event which spread radioactive iodine and other radioactive elements right across the northern hemisphere and contaminated millions of people (not to mention animals and plants). There can be no guarantee that such accidents will not happen again, or that they may be even worse and more devastating next time.

  • Land use. Land that has been used for a nuclear power plant can hardly be used for any other purpose - not only for the lifespan of the power plant but long into the future (even after it is very expensively "decommissioned") due to radioactive contamination and the massive concrete "containment structures" built on the land.

    Sooner or later almost all, if not all, uranium mines and nuclear power plants develop radioactive leaks - some more serious than others. These have cumulative effects - some of which will not become troublesome (or even noticed) for years. However, this continual contamination of waterways and water tables and the oceans will leave a poisonous, and largely intractable legacy for our descendants.

    Decommissioning and cleanup programs overseas have commonly gone way over budget, often running into tens of billions of dollars (a cost that is not usually included in the cost of producing the electricity by the nuclear industry), and are often not very successful in really fixing the damage, or making the site safe for future generations.

    Nuclear plants destroy forever (in human terms) the land they are placed on. This land is usually prime land beside rivers or the sea as they need so much water for cooling (and we have very few seaside or riverbank sites left in Australia that are suitable and available).

    Nuclear power stations put at risk everything downstream of them if there are any accidents, attacks, floods, earthquakes or other disasters - and there are, sooner or later, sure to be such events involving some nuclear plants. Even one such event could kill huge numbers of people and permanently" contaminate much-needed waterways and land. Moreover, almost all nuclear plants and uranium mines experience some toxic and/or radioactive leaks which end up in our very precious and rapidly diminishing water tables. Additionally, the plants heat the water in the rivers which supply them which has led to great biological disturbances downstream in many places.

    In complete contrast, the land used for solar systems, biomass, geothermal, or wind generation would be almost immediately and completely useable for other purposes after such a "renewable" power plant was decommissioned.

    Moreover, during the life of the power plant, much of the land could be used for agriculture and so on. Crops can be grown and cattle grazed under windmills. Solar panels can be placed on top of buildings or to create shade for crops. An earthquake or terrorist attack or flood might well damage the power plant itself, but would be most unlikely to cause any significant "collateral damage."

  • Water use. It is well known that most nuclear power plants use large amounts of water - in fact more than any other form of power generation. Similarly-sized coal-fired plants, which are notorious consumers of water, use significantly less water than nuclear plants (typically about 20% less). "Dry cooling" (in which steam from the turbines is and condensed by forcing large volumes of air through finned pipes) is possible but impracticable. Such systems are very expensive to construct due to the large system of pipes and fans, which, in turn, reduce the efficiency of the power turbines due to back pressure. Australia typically has relatively high ambient air temperatures, so these systems would be even more inefficient than in places with cooler climates.

    Water cooling of nuclear (or coal-fired) power stations can be of three types:

    1. Once-through fresh water cooling. This requires larger sustainable river flows than are available in Australia.

    2. Once-through seawater cooling. Available seaside sites close to major transmission grids are very limited, and may become threatened by the rising seawater levels and increased storm activity over the lifespan of the power station due to predicted climate changes.

    3. Evaporative cooling is probably the best possible option for Australia but it does consume or "waste" huge amounts of precious fresh water through evaporation, even more than coal-fired plants, and astronomically more than sustainables.

      Queensland's Premier, Peter Beattie, recently said an independent study commissioned by the Queensland Government showed a nuclear power station would use 25 per cent more water than a coal-fired power station.

      Mr Beattie said a coal-fired power station that produced up to 1,400 megawatts of electricity a year would use around 19,500 megalitres of water to condense and recycle steam. He said a nuclear power station producing the same output would need about 25,000 megalitres (i.e. 25 billion litres of water). The Premier added: "It is water that we simply cannot afford when drought and climate change are drying up water supplies." If seawater is used instead of fresh water for cooling there would be serious biological impacts on the ocean due to thermal discharge. Renewable energy sources use relatively insignificant amounts of water. According to the California Energy Commission (cited in Paul Gipe's Wind Energy Comes of Age, John Wiley & Sons, 1995), p. 427, conventional power plants consume amounts of water (through evaporative loss, not including water that is recaptured and treated for further use) that are hundreds of times greater than that needed for renewable sources. They estimate that wind turbine plants would consume less than 1/600th as much water per unit of electricity produced as does nuclear, and approximately 1/500th as much as coal.

      It is true small amounts of water are used to clean wind turbine rotor blades in climates where rainfall does not keep the blades clean. The purpose of blade cleaning is to eliminate dust and insect build-up, which can degrade performance. Similarly, small amounts of water are used to clean photovoltaic panels and other types of solar systems. And, except for water used in the production of the plants; that is all that is needed.



Safety (or the lack of it)


The Report goes to great lengths to suggest that nuclear power is safe.

Table 6.2 "Selected nuclear facility accidents, 1966-1999", on p. 70, lists only 31 deaths from Chernobyl. If the nuclear industry keeps scrupulous records of all accidents, as the Draft Report claims, why we are provided with a table that is almost 8 years' old? This figure of 31 deaths is clearly misleading as in the Report further on inn Box 6.2, page 69, we find in small print an estimate that:

"Approximately 4000 people in the areas with the highest radiation levels [caused by Chernobyl] may eventually die from cancer caused by radiation exposure. Of the 6.8 million individuals living further from the explosion, who received a much lower dose, another 5000 may die prematurely as a result of that dose."

Thus the nuclear industry itself expects approximately 9000 deaths will result from the Chernobyl disaster - 3 times as many people as died in the "9/11" terrorist attack on New York - and this figure may well be underestimated. Moreover, these figures refer only to deaths - there is no consideration given to related illnesses or suffering! The Report does not estimate the amount of still-births, deformed children and inter-generational damage and suffering caused by the Chernobyl accident. Box 6.1 on p. 65, gives some technical data on genetic damage from radiation - but no estimates of how widespread this is likely to be - or how many people will suffer because of radiation effects - not all of which are lethal.

Deceptive statements


The Report is filled with numerous half-truths and deceptive wording. Examples include:


  • Page 65, Section 6.1. The opening passage states:

    "All industrial activities, including mining and energy production, involve risks to human health and safety. No means of generating electricity is risk free."

    Although this is literally true, the implication is clearly that nuclear power is not unusual in the risks that it poses. One could hardly argue that nuclear power is safer than wind or solar, tidal, wave, biomass or geothermal power. In fact, the risk of catastrophic disasters will always be present with nuclear power and its by-products.

  • "Table 6.3 Examples of everyday risks in Australia," on p. 72, is particularly misleading because it attempts to compare various risk factors for threats such as cigarette smoking, drowning, motoring, fire, lightening strikes, shark attacks, etc., purportedly showing that the risk of death from the increase in average background radiation is less than everything on the list except death from snake bite or shark attack. Firstly, the increase in background radiation is only one of many risks posed by nuclear power and uranium mining. Moreover, a close read of the notes in fine print under the box reveal the deceptive nature of these figures:

  • The box only gives the increase in background radiation averaged over the whole world. There is no recognition that background radiation is likely to be much higher in regions close to uranium mines, nuclear power plants or nuclear dumps. Additionally, it does not indicate which year the estimates are for, or whether levels are increasing or, if so, by how much.

  • There is no mention that the risk will increase dramatically in Australia if we build a series of nuclear power stations and greatly expand uranium mining and processing, transport and radioactive waste disposal.

  • There is no mention of the risks of accidents, or those posed by terrorists or natural disasters.

    Export of uranium and nuclear proliferation



    Selling uranium for "peaceful purposes" is a goal that is impossible to enforce. For example, in spite of many agreements and "guarantees" that India would only use nuclear power for peaceful purposes, in 1974 they used plutonium from a Canadian-designed 40MW "research" reactor using Canadian uranium to make their first atomic bombs.

    In the cases of countries like India, North Korea, Israel, and Pakistan, having "civilian" nuclear power plants has led to the development of nuclear weapons. What country can guarantee a stable, sensible government in 10 or 20 years time? Even if it were possible to ensure that Australian uranium was only used for "peaceful purposes", this would only free up other stocks of uranium to be used for military purposes. India, for instance, has some limited uranium reserves of its own - so, if it can import enough uranium from other countries such as Australia to run its civilian nuclear reactors it could then, if it wished, divert all of its own reserves to the military.

    International "guarantees" and agreements are hardly worth the paper they are written on. Adequate safeguards are impossible to enforce. We are hypocritical if we do not admit that Australian uranium exports encourage nuclear proliferation.

    Much of Australia's uranium exports already go to countries that are politically and/or geologically unstable, and there are moves to expand that list.

    Some other factors we feel were not dealt with adequately in the Draft Report

  • Australia urgently needs a complete change in our thinking and expectations regarding energy production and use.

    We need to be cutting consumption and not planning for constant increases in the use of electricity. There are many ways to do this with present technology and resources and there will, undoubtedly, be more in the future. For example, one very simple step that could be implemented immediately is to get rid of incandescent globes altogether and replace them with the new fluorescent ones which use approximately 75% less electricity. This would also reduce the power needed for air-conditioning. One report we saw claimed that if all the incandescent globes in the U.S. were changed to fluorescents they wouldn't need a new power station until 2025. That's a pretty good start

  • Nuclear power is excessively expensive, slow to install and can only be viable with large government subsidies which can take several forms (aside from the usual direct financial support, land grants, and tax breaks) such as: not including the clean-up costs after decommissioning, providing alternative power sources in case of shutdown of the nuclear plants (a not uncommon occurrence), allowing companies to put the disposal of wastes on hold indefinitely ("more research needs to be done") - often in very dicey "temporary" containers such as 44 gallon drums, guaranteeing sales of so much electricity per year, and - very commonly - because "peaceful" nuclear reactors give governments the ability to develop nuclear weapons in a hurry if they want to at a future date ("leaving the options open") and thus they are keen to have "peaceful" nuclear facilities.

  • Many reactors have gone way over budget for construction and, later, decommissioning, costs have done the same. Unfortunately, once a major project like the construction of a nuclear plant is begun, it is impossible to cancel it without major financial losses.

  • Many nuclear plants around the world have had to be shut for prolonged periods due to safety concerns - thus threatening continuity of electricity supply to large populations. This common occurrence makes it imperative for planners to design more and larger power stations than otherwise necessary, to assure a constant supply of electricity in case of the shutdown of one or more of these power stations.

  • Nuclear power plants are not good at being able to cope with rapid spikes and lows in demand and so, to be on the safe side, are usually kept up and running at more than needed capacity. Once begun, the nuclear energy industry has a stranglehold on power generation and this will limit new advances and experiments.

    Peak power demand is usually during weekdays during summer, with a big drop-off at night and on weekends. This makes a powerful case for a significant component of solar-generated power. Hydroelectric, geothermal and gas-fired plants are much more responsive to variabilities of power demands than nuclear.

  • New and much more efficient ways of storing both electricity and/or heat (that can be used for producing electricity later) are being developed at the moment which will reduce the need for "demand-time" generation of electricity.

    New storage methods promise continuous baseload power will be available from solar, wind and wave and tidal systems in the near future.

    The new solar cells recently developed at ANU look certain to be able to reduce the cost of production (and the use of energy in producing them) by about 50%. They are past the developmental stage and are just waiting for someone to fund full-scale production facilities. These funds will be very hard to find if we throw most of our resources into the nuclear basket.

    A report was just released by Daily Tech in Illinois yesterday (9th December, 2006) stating that:

    "The United States Department of Energy (DOE) has announced that with the help of government funding, Boeing-Spectrolab has demonstrated a concentrator solar cell with a record-breaking 40.7% efficiency rating. .. . With this new technology, the DOE is projecting that installation costs for these types of solar cells would drop to $3 per watt with electricity costing 8 to 10 cents per kWh. The long-term goal is to have solar energy technology installed in as many as two million American homes providing power at 5 to 10 cents per kWh by the year 2015."

    PC Authority Magazine added on 8th December that:

    "A 33-kilowatt test system is already up and running in the Australian desert and more large-scale trials are planned soon. The cells will also be used on the next generation of satellites."


Conclusion


The Draft Report appears to be heavily biased towards the promotion of uranium mining and nuclear power generation in Australia. Data in it has been frequently employed in a distorted and mendacious way. As such, it cannot be taken seriously and is likely to bring ridicule and embarrassment to both the Australian Government and the nuclear industry as its gross bias and flaws become clear to the public and the scientific community at large. We recommend that this Draft Report be withdrawn immediately in its entirety and a new Report commissioned with an evenly balanced panel of experts representing a wide range of views - not just those of the nuclear industry and its supporters.
