Whether renewables can match the reliability of fossil fuels is yet to be seen even if they do become cheaper than fossil fuels.

BTW that study is with assumed 2030 prices of both commodities.

So to me anyway its a bit crystal ball stuff again.

Most plastics can be recycled effectively and can be manufactured via biological pathways

Bio-plastics

There are alternatives.

And of course humanity needs to change its habits of waste, disposability and addiction to materialism

But this will happen or humanity will not survive

And that means YOU Mr Ajax

Sorry chimp

I'm nor prepared to trade democracy for environmentalism gone sick.

Especially when the drivers are the pigs from the club of rome.

They want to get rich and control us at the same time because they need to save us from ourselves.

We don't need saving and Australia doesn't have to hand billions of dollars over to the United Nations Environmental fund.

The money could be better used here in our back yard.

Retrofitting coal fired power stations with gas fired boilers at the front end, this will reduce our carbon footprint by 25%.

At the back end we could retrofit our power stations with the latest technology in

1. fabric filter bags - soot capture
2. electrostatic precipitators - soot capture
3. CO2 scrubbers - carbon sequestration

Further reducing CO2 emissions.

This will go along way in reducing our carbon footprint.

More than any amount of carbon credits purchased from wall street could ever do.

We don't need to give money to these pigs over at the UN so they can grow rich and be empowered with our dollars.

2030 is only 16 years away. How long does it take to plan and build a new Power Station? The cost justification needs to be for the entire lifetime.

I was trying to find a map showing the total area required to supply 100% Australia's needs using solar. It's a tiny area lost in the Kimberley. (See attached image )



Solar PV is improving in efficiency all the time. This  relatively small concentrating tracking suncube can deliver 711kWh/year.  The efficiency of conventional flat Solar panels is predicted to double in the next 5 years.

Maybe that's pessimistic too:

That's quite an impressive annual power output figure for such as small area.

My Solar PV system produces just under 3000 kW.hr per year - but does not track the sun. The panels are close to facing due north though, at a standard roof pitch angle of 23 deg.

I would estimate from the image you posted that my solar array is about 20 to 25 times greater in area.

So that panel is at least 600% more efficient in terms of power output.

Although if I install a sun tracking system, I would expect to increase my output by about 40%.

So overall that panel is just over 400% more efficient.

capital costs would be higher though but I am sure it would pay itself off quicker overall

In Victoria, when the Ballieau government was elected a couple of years ago, it implemented legislation almost immediately that related to renewable energy options.

Firstly it introduced a 2km veto region surrounding any new Wind Turbine project so that any one or more individual can stop the project from going ahead.

Secondly it reduced the premium solar PV rebate from 60 c/kWhr to 20 c/kWhr then to its current level of 8 c/kWhr.

Both these essentially ended the Wind and solar PV industries in Victoria almost overnight

Where are the 2 km veto laws for Coal fired Power stations, possible nuclear power plants, etc?
