Wind and Solar are Worse than Coal and cause the Waste of Gas


James Hansen, an outspoken world climate alarmist says: “Coal-fired power plants are factories of death”. The Australian Greens want a fast end to coal mining in Australia, and support a swift expansion of wind and solar power. As the Greens are part of the coalition which governs Australia, the electricity industry is now being coerced by carbon taxes and green subsidies and mandates to replace efficient and reliable coal-powered electricity with costly and unreliable wind and solar plants. All of this paranoia is driven by climatist claims that carbon dioxide causes environmental harm by triggering dangerous global warming. Let’s look at whether coal energy or green energy does more harm to the environment.

There is absolutely no proof that carbon dioxide causes any measurable changes to climate. In fact, the evidence indicates that changes in atmospheric levels of carbon dioxide are a result, not a cause, of variations in global temperatures.

Moreover, burning coal in clean modern power stations has definite benefits for the biosphere – it puts food and drink for all life back into the atmosphere. The major coal combustion products are – nitrogen plant food from the air (69%), carbon dioxide plant food from the coal (21%) and water vapour, the liquid for life, from the coal (7%). The other 3% comprises mainly inert atmospheric gases from the air and an ash residue of trace minerals from the coal. The green bogey-man, carbon dioxide, is the gas of life and a free gift from coal combustion to the biosphere. More carbon dioxide has proven benefits in making plants grow faster in good weather and helping them survive better in droughts or frosts. More carbon dioxide in the atmosphere is insurance for the biosphere no matter what climate change is in store for us.

Green energy, however, can affect local climate and does cause environmental damage…

A Lesson on Renewable Energy from a Canny Scot


From: Sir Donald Miller. F Eng. FRSE.
Chairman, Scottish Power 1982-92.

Letter to Alec Salmond
09 March 2011

The Right Hon Alec Salmond
First Minister
Scottish Government

Dear Sir

It is I believe becoming clear to a rapidly increasing number of voters in Scotland that the Scottish Government’s concentration on so called renewable energy sources to the exclusion of more reliable and economic sources , such as nuclear , is little short of disastrous. Let us look at the facts:-

1. No wind or marine energy sources can be relied on to provide power when it is needed- the only time when electricity is of any value.

2. Wind and marine need nearly 100% back up from conventional generators. Therefore any expenditure on these is additional to ‘normal’ capital required to secure our electricity supplies.

3. Output from wind turbines varies rapidly, not just locally but nationally, so that conventional back up generation is required to run inefficiently at part load, incurring further costs for the consumer.

4. Wind and wave are such extremely low density sources of energy that costs will always be high and no amount of development will alter this significantly.

5. The cost of onshore wind to the consumer is some £200/MWhr taking into account the ROC subsidy, back up generation and additional transmission costs. This is over four times the cost of energy from conventional or nuclear sources. The cost of off-shore wind is even higher at over £250/MWhr.

6. The claim that Scotland has vast resources of marine energy is based on a failure to appreciate the physics. The actual potential is readily assessed by normal engineering criteria (as in studies by Consulting Engineers Black and Veatch for The Carbon Trust and Robert Gordons University). These show that the total tidal current resource of UK waters from the Pentland Firth to the Channel Isles, neglecting costs and practical limitations such as interference with shipping and fishing and impossibility of servicing such a plethora of installations, would amount to no more than 2.5% to 5% of UK electricity requirements.

7. The costs of tidal energy to the consumer will be significantly higher than offshore wind, even after taking credit for possible developments. Wave energy will be even more costly.

8. Other low carbon technologies such as Carbon Capture and Storage are unproven on the scale envisaged, requiring long term sequestration of some 200millions tons of CO2 per year from the UK alone. Taken together with the 25% loss in efficiency of generation, energy costs would more than double.

9. Ofgem has estimated that the UK Government’s energy policy will result in a doubling of electricity prices to consumers within 15 years. The much higher renewable targets of the Scottish Government would, on a stand alone basis, result in even higher prices.

10. The CEO of National Grid in a lecture to the Royal Academy of Engineering in March 2011 stated that the effect of present energy policies would be that the era of having electricity on demand in the UK was coming to an end. The UK Government estimates there is a high risk of power cuts within five years.

11. High energy prices based on subsidies are certain to have an extremely damaging effect on the Scottish Economy as recently quantified in the Verso Economics Report using the Scottish Governments’ own economic model for the Scottish economy. The loss of jobs will far outweigh the few gains, most of which will be of low to medium quality, from renewable installations.

12. Already there has been very significant damage to Scotland’s environment- the massive installation at Doune dominating the route North from Glasgow is a case in point- with consequent loss to one of its greatest assets, the tourist industry. The value of tourism to the Scottish economy is put at £4.2bn a year, far in excess of the value of all the energy produced from wind farms even with the Scottish 80% target for renewables.

13. Prior to privatisation Scotland, with six commercial reactors, produced over 60% of its electricity from nuclear and had a thriving and profitable export trade to England. As a result Scotland benefited from having one of the lowest electricity prices in Europe and this after proper allowances for all the costs involved including waste disposal and decommissioning. Unlike the present energy regime there was no element of subsidy. As distinct from other low carbon generation, nuclear is a tried and tested technology of which we have had excellent experience now for over 50 years. Supplies of nuclear fuel are secure and the cost of energy to consumers from a new generation of reactors would be less than a quarter of that from wind and marine sources.

14. The well being of a modern economy is based on a reliable and economic supply of electricity and will be even more so in future as transport becomes increasingly electrified. If one wanted to go down in history as the politician who did most to damage Scotland’s economy it would be difficult to think of a more effective route than the present energy policy.

15. It is not too late to have a rational and balanced energy policy- but it soon will be. We have only a small window of opportunity- let us grasp it before it is too late.

Sustainable, affordable, eco-friendly renewable energy?


Unsustainable cow manure
By Paul Driessen 21 Sep 2010

From http://townhall.com/columnists/PaulDriessen/2010/09/21/unsustainable_cow_manure/page/full/

Seek a sustainable future! Wind, solar and biofuels will ensure an eco-friendly, climate-protecting, planet-saving, sustainable inheritance for our children. Or so we are told by activists and politicians intent on enacting new renewable energy standards, mandates and subsidies during a lame duck session.

It may be useful to address some basic issues, before going further down the road to Renewable Utopia.

Blowing Away Money


Mark Lawson

The Federal Government may have dumped (technically deferred) one nutty green scheme (emissions trading) but an equally nutty scheme remains in place – requiring electricity distributors to buy green electricity.

This scheme is nutty because no one has shown that green electricity supplied to an operating power network actually reduces emissions. The government, various green lobby groups and the mass of voters have simply assumed that it does. There are doubts about efficiency losses due to the whole network having to be retailored to accommodate renewables. And more doubts over just how much additional backup generator capacity will be required for intermittent power sources. These doubts are either ignored or dismissed as “myths”.

The Australian government has dived head-first into renewables with both eyes shut, and with the general approval of the voters, who mostly have no idea of what they have approved or how much it will cost. The government should drop the whole renewable energy scheme as too complicated and expensive and unlikely to save much carbon.

Carbon Sense Newsletter: Silly Roof Schemes


1. Solar Panels – another Silly Roof Scheme

The Carbon Sense Coalition today called for the immediate suspension of another of Mr Garrett’s silly roof schemes – the Roof Solar Panel Scheme.

“This scheme is driven by the Renewable Energy Target Scheme, Renewable Energy Certificates and obligations on power companies to buy the inconsistent dribbles of electricity produced by solar panels on domestic homes.”

The Chairman of Carbon Sense, Mr Viv Forbes, said that like the roof insulation scheme, the Roof Solar Panel Scheme was dangerous, ill planned and a massive waste of community funds…

2. Petition on the Flawed Carbon Trading Scheme

Liberal MP, Dr Denis Jensen, has drawn up a petition on the Flawed Carbon Trading Scheme.

To sign go to: http://petitions.listentous.org.au/signatories/index/pid/16

3. The Big Picture on World Temperature Swings.

Jo Nova has published a set of graphs produced by David Lappi, an Alaskan Geologist.

4. Tampering with the Temperature Records

Joseph D’Aleo and Anthony Watts have produce a masterful analysis of the state of the world instrument temperature records that have been used to support the claims that the world has warmed alarmingly since man started using large quantities of carbon fuels…

5. Chief Warmist Surrenders

Faced with the above and other fast mounting evidence, Professor Phil Jones of CRU, who is at the centre of the “Climategate” affair and a key promoter of the Global Warming Scare, has conceded that there has been no “statistically significant” rise in world temperature since 1995…

6. Big Business gets Nervous

The collapse of the so-called Consensus, the failure of the Copenhagen Climate Confab, the emerging evidence of the foolishness of wasting tax payers funds on wind/solar “power” and ethanol production, the Climategate Scandal, the roof insulation fiasco in Australia, the Carbon Credit frauds, the lack of evidence to support the weekly scare forecasts and the rapid change in public opinion is having an effect on big business support for the Global Warming Scam…

7. The Carbon Wall of Shame

We need a list of the chief promoters of the Ration-N-Tax Scheme and the Climate Change Industry in Australia so that shareholders, customers, employees, tax payers and voters can start putting pressure on directors, politicians, academics and officials who betray us all by refusing to do their homework…

Emissions Targets & Electricity Generation – Some Inconvenient Realities


Touring politicians have a habit of making wild promises in international forums, leaving the difficult engineering consequences to overloaded power engineers and the unpalatable cost consequences to the suffering consumers.

Peter Lang is a professional with more than 40 years experience in the energy industry. His experience includes coal, oil, gas, hydro, geothermal, nuclear power plants, nuclear waste disposal and energy end use management.

Peter has previously written on:

Now he looks at some inconvenient realities concerning the consequences for electricity generation if the government tries to achieve their unrealistic and pointless cuts in carbon dioxide emissions.

The paper compares five “energy mix” options with a “business as usual” case for electricity generation in Australia from 2010 to 2050. The options involve mixes of coal, gas, nuclear, wind and solar thermal technologies. The analysis indicates that continuing with the current mix of electricity sources (mainly coal) will provide the cheapest electricity. Gas, the other carbon fuel, has the next higher cost. All of the non-coal options (nuclear, solar and wind) will substantially increase electricity costs with solar being the most expensive.

Nuclear power is the only feasible option that could achieve the promised cuts in emissions. Wind and solar are very high cost options with little hope of achieving the emissions cuts promised, either alone or in combination.

Of Cabbages, and Kings, and Tariff Feed-ins


“The time has come,” the Walrus said,
“To talk of many things:
Of shoes–and ships–and sealing-wax–
Of cabbages–and kings–
And why the sea is boiling hot–
And whether pigs have wings.”

The Walrus and The Carpenter, Lewis Carroll, from Through the Looking-Glass and What Alice Found There, 1872

Once upon a time there was a land where cabbages were very popular. People used them for all sorts of things. There were central farms where they were grown, and distributed to supermarkets from where people bought them. The subjects in this land could buy the cabbages for about 17 cents each.

One day the King decided that it was a bad thing for the cabbages to be produced by these large farms. He said it hurt the environment to have them transported all the way to the supermarkets. He also said too much water was used on those farms.

Solar Power Realities – Addendum


By Peter Lang

This paper compares the capital cost of three electricity generation technologies based on a simple analysis. The comparison is on the basis that the technologies can supply the National Electricity Market (NEM) demand without fossil fuel back up…

The three technologies compared are:

1. Nuclear power;
2. Solar photo-voltaic with energy storage; and
3. Solar thermal with energy storage.

Solar Power – a Subsidised Appendage


By Viv Forbes, Chairman, The Carbon Sense Coalition.

Australian electricity consumers can look forward to soaring charges for electricity and blackouts if state and federal politicians continue to undermine the power grid by mandating and subsidising solar power generation.

Solar power can never produce continuous, predictable low cost power. It must always be supported by expensive power storage systems or by reliable power sources such as coal, gas, hydro or nuclear.

No matter how many millions of taxpayer money is poured into “research”, it can never solve the two fatal flaws of solar power.
