  1. I’d listen to what Elon thinks about your scenario. Happy to have Nuclear backup for renewables. Solar and batteries in a country that has huge solar capacity. We are supposedly going to supply Singapore with electricity. Batteries are improving with better technology and components. 🇦🇺

  2. It is not difficult to debunk the "renewables" debacle that Labor is pursuing. This presentation makes it quite clear what is terrible disaster Labor is taking us towards. Even if Gerard's analysis is not quite right in the detail (as he points out re economic discounting) the difference between "renewables" and nuclear is so very large. Agree – keep the coal/gas on until we can turn on the nuclear plants. A little, maybe 20%, wind and solar would probably be positive in the mix.

  3. This is good viewing, but it talks about a 100% renewable scenario, not a 80% scenario. 🙃👎
    And that last 20% is where almost all the over-the-top crazy costs lie. ^^

    Not to mention he didn't comment on how technological progress/ inflation will affect costs in his model. 👀 Given his seeming bias, a renewable scenario might be cheaper than he claims. 🤷❤️

    It seems a better 20 years goal for Australia is energy coming from 60% nuclear, 30-35% from the renewables & storage technologies, and 5-10% of classical fossil fuel generation, to cover for unusual variability in demand.

    Credentials: I studied electrical engineering in my home Slovenia, with emphasis on power generation, transmission & regulation. I follow it with a passion, and also invest in companies connected to it on the stock market.
    Greetings & Love 🙏❤️

  5. Live liberty and the pursue of happiness, has become death, slavery, and the pursuit of money. Nuclear fusion is coming eventually, get an education. I can only assume that this idiot has some vested interest such as shares in a relevant corporation.

    Lies, damned lies and statistics.

  6. Nuclear creates radioactive waste. Not economically viable or soon enough to stop an already catastrophic irreversible climate change that is wrecking countries right now. Witness hurricane Helene and Spain's floods. Nature bats last.
    It's a miracle that humans haven't already gone extinct. We only have time to be kind to each other.

  7. Treasonous what our government is doing. Unbelievable. And what happens to these solar / wind farms in a massive destructive storm? They would be knocked out overnight.

  8. Okay, there needs to be at least another starting graph – measuring the speed at which the current rooftop solar adoption rate, which is now somewhere between 30-40%, arrives at the tipping point where solar and battery consumers disconnecting from the grid because of a better product at a much cheaper price render the grid unstable to the point where it becomes a stranded asset.

  9. Wow 95 % truth not bad. Remaining 5% (reasons for Germany energy collapse due to switching off Nuclear power houses by green fanatics and sabotage of Nord stream -not invasion of Russia in Ukraine) we understand

  10. $2.57 trillion … let's get the socialists and Turnbull Renewables out of the economy. The clincher is that our entire energy grid will depend on China's rare earth minerals. Just follow the money, it's not hard to see why the current government is red hot on this.

  11. It's actually a lot worse than this. He forgot something. While you're getting electricity from wind and solar, you're using it, you can't charge batteries. So you need one full duplicate copy of all solar and wind infrastructure to charge the batteries, and that's just for another day of storage. Every day of extra stored electricity you want, you need a full complement of wind and solar to generate that electricity ahead of time. So if you want to prepare for five days without solar and wind, you need to multiply everything in the left-hand stack by five. And now you need batteries that can hold the charge and run a grid for a week or two, and those don't exist. So the column on the left is many times higher than shown.

  12. A very sound and logical take on this energy debacle that has now been thrust upon us; the common man, by this leftist dispensation. A realistic forward thinking solution as compared to the short term one being peddled to the rest of our citizens, Who has benefitted the most from this, definitely not the future generation of the majority of Australians. Someone should check on who the owners are of the businesses tasked with delivering this renewable exercise. Go woke go broke.

  13. Clean nuclear energy apart from the 100000 years of radioactive waste nobody knows what to do with. Is encasing the whole spent nuclear plant in concrete factored into the energy equation. Just keep burning coal and oil if you don't care about future generations.

  14. Why is the maintenance of existing grid network not added into the cost.
    Also if the end user stores their own power in car / house batteries isn’t that free?

  15. Absolutely wonderful to highlight that "Energy Security is National Security"

    I remember the early 80s and NSW had power rationing where businesses had to shut for 1 day a week in the Sydney basin… The state government then built all the coal plants the ones they want to close now.
    Trading reliability and security off for the worst power is madness.
    Australia needs Reliable and Secure power for the future and security of a future Australia.
