What is NSW Premier Gladys Berejiklian thinking?
It has been revealed that her energy minister Matt Kean, fresh from legislating his green new deal to close all coal-fired power in NSW, is giving $10 million of taxpayer money to a Chinese Communist Party-controlled company to build windmills.
That’s right. As the CCP shores-up its strength by building 100 new coal-fired power stations, Kean is paying the CCP to weaken Australia with expensive and unreliable wind power.
Kean and Berejiklian want to close down the remaining coal-fired power stations in the Hunter Valley and replace them with CCP-made wind turbines which only serve to hike the price of electricity and make it unreliable.
Goldwind Australia, a subsidiary of a CCP-controlled company is getting the cash, straight from the taxpayer’s pocket.
The NSW Hunter Valley coalfields are adjacent to the world’s biggest coal export port at Newcastle.
The comrades in Beijing must think we are fools for tearing down coal and erecting their windmills. They would not be wrong.
Belling the cat on all this has been NSW One Nation Leader Mark Latham. He’s been supported by Nationals Matt Canavan and Barnaby Joyce and courageous federal Liberal Craig Kelly.
It’s been crickets from virtually everyone else.
That’s why Advance keeps banging on. As more and more mainstream Australians wake-up to the CCP sell-outs in our parliaments and their globalist bedfellows at the World Economic Forum, there will be a reckoning.
Thanks for your part in powering the awakening.
Largely useless eyesores, these towers have a limited lifespan and what happens after they expire? As we have said fo years: “the only wilderness left in Australia is between a greenie’s ears”
What is the carbon footprint of a wind turbine with 45 tons of rebar & 481m3 of concrete?
Its carbon footprint is massive – at 241.85 tons of CO2.
Here’s the breakdown of the CO2 numbers.
To create a 1 tonne (1,000 Kg) of pig iron, you start with 1.8 tonne (800 Kg) of iron ore, 900 Kg of coking coal 450 Kg of limestone. The blast furnace consumes 4,500 Kg of air. The temperature at the core of the blast furnace reaches nearly 1,600 degrees C (about 3,000 degrees F).
The pig iron is then transferred to the basic oxygen furnace to make steel.
1,350 Kg of CO2 is emitted per 1,000 Kg pig iron produced.
70% of steel is made from Coal: A 1 MW of wind turbine capacity requires 220 tonnes of coal.
A further 1,460 Kg CO2 is emitted per 1,000 Kg of Steel produced so all up 2,810 Kg CO2 is emitted.
45 tons of rebar (steel) are required so that equals 126.45 tons of CO2 are emitted.
To create a 1 tonne (1,000 Kg) of Portland cement, calcium carbonate (60%), silicon (20%), aluminium (10%), iron (10%) and very small amounts of other ingredients are heated in a large kiln to over 1,500 degrees C to convert the raw materials into clinker. The clinker is then interground with other ingredients to produce the final cement product. When cement is mixed with water, sand and gravel forms the rock-like mass know as concrete.
An average of 927 Kg of CO2 is emitted per 1 tonne (1,000 Kg of Portland cement. On average, concrete has 10% cement, with the balance being gravel (41%), sand (25%), water (18%) and air (6%). One cubic metre of concrete weighs approx. 2.4 tonne (2,400 Kg) so approx. 240 Kg of CO2 is emitted for every cubic metre.
481m3 of concrete are required so that equals 115.4 tons of CO2 are emitted.
Not included are the emissions of the mining of the raw materials or the transportation of the fabricated materials to the turbine site. So the emission calculation above would be on the low end.
Extra stats about wind turbines you may not know about:
The average towering wind turbine being installed around beautiful Australia right now is over 80 metres in height (nearly the same height as the pylons on the Sydney Harbour Bridge). The rotor assembly for one turbine – that’s the blades and hub – weighs over 22 tonnes and the nacelle, which contains the generator components, weighs over 52 tonnes
This stands on a concrete base constructed from 45 tonnes of reinforcing rebar which also contains over 481 cubic metres of concrete (that’s over 481,000 litres of concrete – about 20% of the volume of an Olympic swimming pool).
Each turbine blade is made of glass fibre reinforced plastics, (GRP), i.e. glass fibre reinforced polyester or epoxy and on average each turbine blade weighs around 7 tonnes Kg each.
Each turbine has three blades so there’s 21 tonnes Kgs of GRP and each blade can be as long as 50 metres.
A typical wind farm of 20 turbines can extend over 101 hectares of land (1.01 Km2).
Each and every wind turbine has a magnet made of a metal called neodymium. There are .5 tonnes of it in each one that have just gone up around Australia.
The mining and refining of neodymium is dirty and toxic – involving repeated boiling in acid, with radioactive thorium as a waste product – that only one country does it – China.
All this for an intermittent highly unreliable energy source of electrickery
Now, considered the manufacture of the thousands of pylons and tens of thousands of kilometres of transmission wire needed to get the power to the grid. And what about the land space needed to house thousands of these bird chomping death machines?
Renewables like wind turbines will incur far more carbon dioxide emissions in their manufacture and installation than what their operational life will ever save.
Doesn’t the false pollution “cure” of using wind turbines sound worse than the problem? A bit like amputating your leg to “cure” your in-growing toe nail?
Germany’s Renewable Energy Fail: German CO2 Emissions 10 Times Higher than Nuclear- France
Germany has added 30,000 wind turbines and millions of solar panels to a coal fired grid and its carbon dioxide gas emissions continue to rise and are magnitudes higher than its nuclear-powered neighbour, France.
Australia signatory to Agenda 21 since 1992
No power for 2 million California residents
In NSW, 23,500 customers had power cut off last year, unable to pay bills
by Alex Bruce
It’s funny how so many topics once deemed to be “Tinfoil Hat conspiracy theories” keep getting proven to be worthy of serious attention. Agenda 21, the United Nations’ 1992 plan for Sustainable Development is an example.
Rosa Koire has been doing an excellent job of raising awareness about Agenda 21 for many years. She describes how it is being rolled-out – never by name. This is carefully avoided. Hence, we’re propagandized about Climate Change and the Green New Deal. She says Agenda 21 programs can be identified by their so-called “communitarian” ethos that is imposed from without by NGOs, circumventing the will of communities and the individuals within.
Agenda 21 has been getting pushed hard lately in the agitprop of Greta Thunberg and Alexandra Ocasio-Cortez. Among its unrealistic goals, the Green New Deal aims to restructure the entire global energy economy within 10 years by completely “transitioning” the US out of fossil fuels and nuclear energy and into renewables, like wind and solar power.
What none of its proponents will admit is that this plan requires genocide. As shown by the collapse of Rome and demonstrated repeatedly by successive societies, the halving of energy consumption leads directly to the collapse of human populations.
As a Bay Area forensic commercial real estate appraiser and expert witness, Rosa Koire observed how property owners in Northern California have been barred from using their own properties, thus making these cheap when the Government wants to acquire them for Eminent Domain.
While investigating this, Koire ran into Agenda 21 – or as she calls it, “The biggest public relations scam in the history of the world,” and how this global plan aims to break down economies and to depopulate areas considered to be rural or suburban, concentrating populations into larger cities.
“This is the plan. It’s the loss of our industry, our agriculture, our food independence. Ultimately, it’s the loss of our sovereignty, as a free nation…It’s social engineering…it’s the acceptance of what I call the ‘new poverty’.”
Over two million people in California were left without power this week and several hundred thousand remain without power during a preventive blackout by PG&E lasting several days. The energy company’s promise to make a massive outage like this the new normal will likely drive many people away from the rural areas and thus fulfill the plan of Agenda 21.

What Produces Warmth?
I live in SE Queensland. Yesterday the surface air temperature rose from a frosty 2ºC at sunrise to a balmy 22ºC in mid-afternoon. The enormous heat needed to achieve this 20ºC of warming came via radiation from the sun. Carbon dioxide in the atmosphere plays no significant part in this daily heating event – in fact it may intercept a tiny proportion of the incoming solar radiation and re-radiate it in all directions, thus keeping the daytime surface temperature a tiny bit cooler than it would have been otherwise.
At the deep Mount Isa Mine in NW Queensland, the surface temperature may average about 25ºC but it increases by about 1ºC every 50 metres of depth – rock walls are red hot in places. The enormous heat causing this comes via conduction from Earth’s internal geothermal heat plus some oxidation and heating of the sulphide ores as they come in contact with natural air containing oxygen. Carbon dioxide in the atmosphere plays no part in this heating.
There are volcanic windows open right now in Hawaii, Japan and the Galapagos revealing the vast resources of volcanic geothermal heat which is always migrating towards the cooler surface, sometimes violently.
Temperatures vary greatly over Earth’s surface, making a mockery of attempts to calculate an “average” for the globe. Air surface temperature may be minus 30ºC at the South Pole, while at the same time it can be plus 30ºC at the Equator. This enormous difference is caused by the varying intensity of solar radiation striking the surface – carbon dioxide in the atmosphere plays no significant part in creating this variance.
Surface air temperatures in big cities can be 5-10ºC hotter than surrounding rural land partly because bitumen roads, roofs, solar panels and runways heat up more than grassy or forested countryside. Mega-cities are also full of heat-producing humans, engines, trains, vehicles, air conditioners, heaters, stoves, fridges, pumps and mowers.
Urban heat also comes from the warm bodies and hot exhalations from millions of humans digesting carbon-based foods, from stored chemical energy from burning hydro-carbons (wood, lignite, coal, oil and gas) or from nuclear power. Using green energy also adds to urban heat. Wind towers and solar farms extract energy from wind and sun in the country-side and release it where most of the electricity is used, usually in cities and suburbs. Aging black rooftop solar panels convert much of the solar radiation into heat not electricity, thus adding to urban heat. Carbon dioxide in the atmosphere plays no measurable part in producing these islands of urban heat.
Longer term, the Medieval Warm Era and the Little Ice Age were natural fluctuations in solar system orbits which affected the intensity of solar radiation received on Earth. The bigger ice ages (like the one that ended just 12,000 years ago) were also triggered by solar system cycles and magnetic reversals which activated submarine volcanic activity along Earth’s extensive mid-ocean trenches/ridges. Human production of carbon dioxide into the atmosphere played zero part in these natural global warming and cooling episodes.
Carbon dioxide in the atmosphere varies annually with the seasons reaching a maximum in the South Hemisphere summer for two perfectly natural reasons.
First, the huge southern oceans expel carbon dioxide as the surface water warms with the return of the summer (like an opened bottle of soda water in the sun).
At the same time it is turning to winter in the large northern hemisphere landmass where deciduous trees and forests are dropping their leaves, and crop residue is accumulating on cultivated lands. As this dead plant material decomposes it recycles its CO2 to the atmosphere. And as winter grips these densely populated lands, humans are also burning wood, peat, cow dung, coal, oil and gas to keep warm, releasing even more CO2.
Then as the sun-driven seasons change, the southern oceans cool again and much of this carbon dioxide returns to the sea from whence it came. And the northern farms and forests grow faster in their summer, absorbing atmospheric carbon dioxide and solar energy to produce food and lumber.
This annual fluctuation of carbon dioxide in the atmosphere is a result, not a cause, of the seasonal temperature changes.
What happens in the seasonal weather cycle also occurs as a result of longer climate cycles of cooling and warming. The ice core records show that the changes in global temperatures precede by about 800 years any changes to the amount of carbon dioxide in the atmosphere. This is probably a result of large slow overturning in the oceans as global temperatures change in response to cycles of solar energy and earth volcanism.
Despite all of this evidence of natural changes in Earth’s temperature, man’s production of invisible life-supporting carbon dioxide is being slandered daily with words like “dirty” “black”, “polluting” “heat causing”. And those who point to dissenting evidence are called “deniers”, “shills” and worse, and gagged by intimidatory law suits, internet censorship and media silence.
Billions of dollars are also being spent on a propaganda storm of anti-carbon scare stories, Papal proclamations, cunning calculations, doctored data, and poignant pictures about polar bears, penguins, koalas, super-storms, social costs, floods, fires, mega-droughts, heat waves and blizzards, all supposedly impacted by man’s production of atmospheric carbon dioxide. With just 0.04% in the atmosphere, to create such havoc carbon dioxide must be the most powerful super-gas ever imagined by the alarmists.
The green mafia is trying to lynch an innocent victim – the gas of life, carbon dioxide. They would be better served by focussing on real pollution of air, land and water caused by their own well-travelled, air-conditioned, electronic, fast-food, throw-away, tax-supported lifestyle. If they fear carbon dioxide so much, they should stop exhaling.
We need more light and less heat in the climate debate.

Powering the Portland Aluminium Smelter
Lessons for Victoria from South Australia
Alumina chairman, Mr Peter Day, said recently that his company was “agnostic” about the source of power to the smelter, so long as it was affordable and reliable.
“There have been many years of energy policy making that have effectively reduced energy security and reliability and substantially increased energy costs for industry.”
Victoria has plans to follow South Australia’s example by installing a grid-scale battery, but Mr Day said even Tesla’s new Hornsdale Power Reserve in South Australia (the world’s largest lithium ion battery) would not be sufficient to run Portland.
“If it was fully charged and available, it could run Portland for around 20 minutes,” he said.
Renewables can’t power aluminium smelter:
A reader commented:
“At 0955 on 23/6/18, South Australia’s electricity demand and generation was:
- Demand 1551 MW
- Generation in SA 853 MW
- Wind and other 0 MW (this is not a misprint, it was zero)
- Import from Victoria 717 MW
“The data above is nothing unusual and was sourced from AEMO’s data dashboard. Just for fun, I monitor it every day and believe me it is not a pretty sight.”

“Daring to Doubt”
by Tony Abbott:
“Climate change is by no means the sole or even the most significant symptom of the changing interests and values of the West. Still, only societies with high levels of cultural amnesia could have made such a religion out of it. Beware the pronouncement, “the science is settled”. It’s the spirit of the Inquisition, the thought-police down the ages. Almost as bad is the claim that “99 per cent of scientists believe” as if scientific truth is determined by votes rather than facts.”

“Escaping the Renewable Energy Trap”

“The Paris Agreement”
by President Donald Trump
What he really said.
Serious Defects in Australia’s Energy Policies
“… As President, I can put no other consideration before the wellbeing of American citizens. The Paris Climate Accord is simply the latest example of Washington entering into an agreement that disadvantages the United States to the exclusive benefit of other countries, leaving American workers — who I love — and taxpayers to absorb the cost in terms of lost jobs, lower wages, shuttered factories, and vastly diminished economic production.
Thus, as of today, the United States will cease all implementation of the non-binding Paris Accord and the draconian financial and economic burdens the agreement imposes on our country. This includes ending the implementation of the nationally determined contribution and, very importantly, the Green Climate Fund which is costing the United States a vast fortune….”
A group of retired senior engineers challenge Australia’s bi-partisan energy foolishness. See:
Senator Malcolm Roberts told a meeting of Lakeland residents on Sunday he was surprised the developers of a massive windfarm project would have advised them there was no government requirement to conduct public notification or consider public submissions.
The One Nation Senator visited Lakeland at the request of landowner Joy Marriott, one of the closest neighbours to be affected by 35 towers, up to 240 metres high.
In a letter from the proponents, Windlab, residents were told the Department of Infrastructure, Local Government and Planning is currently assessing the development application for the wind farm.
“They have confirmed with us that there is no requirement to conduct public notification or consider public submissions. However, you can still make a submission by writing to the Department ,”wrote spokesman, Joshua Petrass.
Ms Marriott said the company was not required to undertake an Environmental Impact Study, “yet when a Lakeland business applied to extend its accommodation facilities the council insisted on a very strict application process that involved an EIS and planning that will cost a lot of money.
“I had to do a similar process when I started my now nearly completed caravan park and it cost a lot of money, so I can’t see how a southern developer can come to Lakeland with a $200 million wind farm and not do an EIS or take any notice of objections.”
Wind-generated power did not receive top marks from Senator Roberts. He warned that the huge increase in power prices across the State was caused in part by subsidised renewable power.
A mining engineer by profession, Senator Roberts warned that wind power was not all it was made out to be.
“My research shows that wind power destroys the security of electricity supply because it is asynchronous (not occurring at the same time) and it destabilises electricity supply,” Senator Roberts explained.
“It relies on subsidies from taxpayers and can be harmful to physical and mental health as well as harm the environment, but it can also destroy property values.
“Wind towers are not aesthetically pleasant, but worst of all wind farms are based on a lie-Australian industry is not affecting the global climate.”
In the letter, Mr Petrass said Windlab seeks to partner with the community to bring economic development and investment in renewable energy.
