43% reduction by  2030, only 8 years away. with only c. 50 deniers in the Oz parliament. 

Keep dreamin' Wink


The UN welcomed Albo's commitment today. If anyone can achieve a 43% reduction in CO2 emissions by 2030, Oz can.

So we will see how that works out, or not


I expect everyone around the globe will wake up, in the years ahead,  that public financing, not private,  will be necessary to complete the transition in a timely manner.

Meanwhile in Oz, hopefully the Greens will allow as much gas usage as is required, while we  transition  to green,  ASAP.
I think they will want to avoid the mistakes of a decade ago; and there should be no reason why we need to develop  NEW gas fields....

The Pilbara can be exporting green electricity to Singapore well before then.

It will work, as Tim Buckley said today :the cheapest fastest NW energy in Oz is rooftop and grid upgrade.

Tim Buckley apparently knows finance. Also apparently he knows nothing of rooftop solar. Solar changes by the minute. It is not and cannot provide reliable energy.

Oz has sufficient gas to firm a fast roll-out of interconnected roof-top solar, while longer term pumped- hydro storage is developed.

Definitely the cheapest way to reach net zero.... by whenever.... depending on resistance by filthy fossil price gougers.

Just plain common sense:

(google)

"potential rooftop solar capacity in Australia"

179 gigawatts

Australia's estimated total potential for rooftop solar is 179 gigawatts with an annual energy output of 245 terawatt-hours – exceeding current electricity consumption on the main grids in Australia.

Edit: The study used 62.5% nameplate capacity not generated capacity. Capacity factor is about 30%. Wink

And the sun doesn't shine all the time. Even during the day. And batteries won't cut it, As has been explaoinde4d to you many times. Roll Eyes

As I said Neither Buckley nor you know even basic engineering., Roll Eyes

Where is the scope in WA for pumped hydro? it is largely flat. Wink

The GDR (inc. Snowy 2 ) and Tasmania ..the "battery of the nation"....interconnected.

Even exporting electricity to Singapore, from the Pilbara.

Another green pipedream.

But why didn't you tell us more on this you beaut rooftop solar.  Roll Eyes

In case you think I am a numpty like you -Excerpt from the study referenced -

"A PV intensity of 156.25 W/m2 (based on generic 250 W modules sized 1.6 m x 1.0 m) was applied to the usable areas to determine PV capacity for each zone and postal area (POA)."


https://apvi.org.au/wp-content/uploads/2019/06/isf-rooftop-solar-potential-repor...

Edit: That was wrong Sri. A 250w module at 1.6m2 that would make 1M2 250/1.6 = 156.25. So they are using 100% capacity factor. a 30% capacity factor would be 46.875w/m2

Worldwide, there could be more than 40 million tonnes of blade waste in landfills by 2050.

Wind turbines have life span of 10 to 20 years and are expensive to break down due to their size and the fact they are made from a mixture of composite materials including glass fibre, carbon fibre, polyester and epoxy resins.

Professor Majewski said the turbines could be recycled but it was yet to become a lucrative business.

"The key problem is there is not a lot of money in it, so recyclers don't have a huge income stream," he said.

"We need the government to provide incentives for energy companies."

https://amp.abc.net.au/article/101168442

Government = you, the taxpayer and energy user.

Just goes to show there is no future for energy, in markets. Good, old-fashioned nationalization is the way forward.

Correct; hence the need to free the taxpayer from the clutches of the greedy private financiers who still claim the sole right to create money - with interest.

Quote:
In signing off from Siemens Gamesa after three years that might diplomatically be described as ‘eventful’, I wrote to colleagues that: “I suspect it will get worse before it gets better, but it will get better”.

One of the first responses I received was very instructive: “When I joined more than 15 years ago, I was told that I was joining the sector with the brightest and most promising future. The problem is that it is a future that seems never to come.”

It is fair to say that that sums up much of the prevailing mood in the wind turbine OEM sector right now with all the major western OEMs struggling to turn a profit. It is not unusual to hear senior industry figures raising the spectre of the fate of the European solar manufacturing industry, long ago lost to the east.

And here is the paradox of the wind energy industry in 2022: if net zero and other decarbonization targets are to be met, the industry should be on the cusp of a growth phase that would dwarf anything experienced so far.

The question is whether the western manufacturing sector will be in any sort of shape to deliver that growth, or it will endure the fate of the long lost solar industry, a spectre now regularly raised by industry leaders.

Logic dictates that this is the moment to press down hard on the accelerator, designing the technology and building out the capacity required to quadruple installations between now and 2030.

Instead the news is full of stories of lay-offs, factory closures and eye-watering financial losses. And the resources required for the necessary investments are in jeopardy.
Post-covid malaise

The issues are well known. The industry’s relief at surviving Covid relatively unscathed and its optimism about a green recovery are long gone, replaced by a supply chain crisis and a damaging imbalance between supply and demand of projects.

The resulting competition is fierce and not conducive to healthy margins.

And all this at a time when the case for wind is more compelling than it has ever been.
