Pre-Federation Australia: A Coal Goldmine
The first mention of coal in Australia’s history books dates back to 1797 in NSW and marks the beginning of a lucrative history with Australia’s 2nd largest export and economic influence today.

Throughout the 1800s coal was discovered in just about every state in Australia, and as technological advancements led to means of converting this resource into power, long gone were the days of gas powered lighting and soon enough major cities history with electricity had begun.

Where did the gas for Australia's gas-powered lighting come from before coal?

Orginally probably came from whales
which is a renewalable source apart from killing moby

Australia made gas out of coal and stored on in huge tanks scattered over the suburbs they called them gasometer from memory

"Australia has 116 new coal, oil and gas projects in the pipeline. If they all proceed as planned, an extra 1.4 billion tonnes of greenhouse gases would be released into the atmosphere annually by 2030.

To put that in perspective, Australia’s total domestic greenhouse gas emissions in 2021–22 were 490 million tonnes. So annual emissions from these new projects would be the almost three times larger than the nation’s 2021-22 emissions. That’s the equivalent of starting up 215 new coal power stations, based on the average emissions of Australia’s current existing coal power stations."

Dodoo I am not up on all these projects, but Australia is a large exporter of coal and gas. Are you claiming the consumption of these new projects is for domestic purposes? Australia is building no new coal fired electricity stations, instead it is steadily closing them down, so Australia tripling it's domestic co2 footprint seems unlikely

Read yourself and as to your questions read what I posted and then your questions make no sense

[Whistler]

Doodoo, the report 100% confirms what I wrote about exports. We only count domestic CO2 emissions, not emissions generated from fossil fuels exported.

[Doodoo]

"But as we share the atmosphere with the rest of the people on the planet, the consequences will come back to bite us."

Unless Australia is going to build a CO2 wall

Correct, but what is counted as DOMESTIC CO2 emmissions today by country, it is measured by consumption of fossil fuels, not production of mining exports. You cannot count them twice, once in the country of production, and once in the country of consumption.

you posted 'To put that in perspective, Australia’s total domestic greenhouse gas emissions in 2021–22 were 490 million tonnes.

The 2021-22 490 million tonnes of CO2 did not include energy exports for that year, but the additional 1.4 billion tonnes is primarily if not exclusivly, exports only. The truth is, Australia's domestic CO2 footprint is dropping, not tripling.

[Doodoo]

"The truth is, Australia's domestic CO2 footprint is dropping, not tripling."

Not according to "Richard Denniss, Adjunct Professor, Crawford School of Public Policy, Australian National University"
Not a Brit , not an American , not a Canuck but an Aussie. So best go argue with him

[Whistler]

Quote him when Doodoo? Richard Denniss is an outstanding, plain talking and practical academic, The Australian Institute is also a great think tank. Denniss's last major paper on Australias's co2 emissions was in September 2021 and focussed on the dodgy practice of offsetting carbon credits against actuals to BS about emissions.

Things in May 2024 are significantly different. From a very recent and credible source, Australia is reducing its domestic co2, but increasing exports of CO2 fossil fuels.

Go complain to him that his articles are misleading then and you dont understand them

[Whistler]

Doodoo, if you want to grab the bull by the horns, approach from the front. If not, the bull will not take kindly to the appendages you grab.

RD was not in the slightest bit misleading, great comments that are easily understood, and salient.

You misrepresented what Richard Denniss actually said, selectivly quoting his comments, out of context, and out of date.

[Doodoo]

Next time you bump into him give him my regards

[Whistler]

Will do, he has a great sense of the ridiculous. 55

Seismic surveys are the first step for oil and gas exploration as well as field development and exploitation. Thus the environmental impact of 'seismic blasting' has been debated for decades. More recently, the same survey techniques serve the development of carbon capture and storage and windfarm sites. This has predictably re-heated the debate on whether it kills whales, other marine life and aquaculture.

An interesting article about it appears in an interesting publication.

12 States Are Banning the Sale of Gas-Powered Cars

Seventeen states have historically followed California's regulations, but so far only Delaware, Maine, Maryland, Massachusetts, New Jersey, New York, Oregon, Pennsylvania, Rhode Island, Vermont and Washington have announced they'll enforce the Advanced Clean Cars II rule and prohibit the sale of new gasoline-powered vehicles.

Not competitive’: Coalition slammed over nuclear as data reveals eye-watering cost


...Independent estimates published on Wednesday by the CSIRO found building Australia’s first large nuclear reactor would cost at least $8.6 billion, and would take upwards of 15 years.....

..... The GenCost report was designed as a “technology-neutral” assessment of power generation costs and in 2024 has for the first time run the ruler over what nuclear might cost taxpayers.

It’s estimated electricity from a large-scale nuclear reactor would cost between $141 and $233 per megawatt hour (MWh), while a small-scale reactor costs between $238 and $382 per MWh.

Renewables, meanwhile, were costed at between $73 and $128 per MWh, even when firmed......

..... The report also warned that a nuclear reactor couldn’t be up and running until at least 2040 and that the cost of building one could even double without an established nuclear power industry.....

And that's before trying to find someone to finance the construction, and then insure the ongoing operation.
