Oh, dearie, dearie me, Lee, what should we do about Climate Change? Nothing?

It hasn't shown itself to be harmful, and even beneficial. Wink

Oh, dearie, dearie, me, where do you live, Lee? Antarctica? We have witnessed the climate changing markedly in the last 10 years, a change you refuse to admit to. The rest of us has noticed it, even if you refuse to admit to it. Tsk, tsk, tsk... Roll Eyes

You haven't witnessed the sky falling Chicken Little/Henny Penny Grin

Though I'd say you'd more likely be the Goosey Loosey type or a Turkey Lurkey.

And you don't talk for the rest of us or anybody.

Why can’t we simply agree on a renewable path and begin building nuclear back up?

Why must it be either one or the other?
As we move forward too a big Australia we cannot ever have enough power for electricity.

I live here too, I experience flooding and fires and cyclone.

All these natural events always have a significant impact on essential services.

I believe we should be building both renewable energy and nuclear energy.

I don’t understand the argument it must be only one???

We should hedge our bet!

Our bet would cost billions of dollars more if we built nuclear power stations. A renewable bet would cost billions of dollars less. Tsk, tsk, tsk... Roll Eyes

Bullshyte you have exactly no proof that that is anywhere near truthful.

They way they're spending money on more & more solar & wind projects it will soon make 6 or 7 nuclear power stations look cheap.

You don't know how much it will cost, do you?

We need a new transmission system because the uncertainty created by the coalition over the last few decades has lead to underinvestment in our electricity industry. Whatever option we choose is going to be expensive. A decentralised system based on renewables, including a lot of solar and battery storage in and around major cities, may well end up being the cheapest option.

How much energy do batteries supply? For how long?

Please explain.

False. Renewables need new transmission lines because they are not where the electricity is needed. Wind Turbines are spread about 750m apart. A bank of 24 needs a lot of new transmission line. Expansion of Warradarge in WA is to be a new 30 turbines. Vestas make a 15MW turbine, but in Australia 6.2Mw is more usual.

A nameplate capacity divided by the turbine specs will tell you how many wind turbines are needed and then work out your 750m separation.

Please explain.

Batteries are a short gap solution, WA has spent 2.8Bil on a battery storage of 2000mw/h. This can give you 2000Mw's of power for 1 hour. On the WA grid that would last about 1.5 hours and then the batteries are flat and will need recharging. They will be used to try and even out the load on the grid.

For example on hot days when the load is very high they can discharge 20% of the batteries to decrease the load on other assets. Batteries do not produce electricity they only store it. You have to have the capacity to charge the batteries and there are losses of efficiency when you transfer the energy to the batteries and when you discharge the batteries. Battery life is very short and will need replacement within 10 years.

That maybe correct for the very short term (5-8 years) but over 40-50 years it will be much cheaper to have nuclear. It doesn't matter how you twist and mutilate the figures nuclear power is by far the cheapest option.

I think they are right where they are needed. You can even put them in the CBD if you want.

What about the next 100000 years that you need to safely store the radioactive waste for?

Renewables are cheaper, even if you ignore the waste storage dilemma.

If you want to be sensible we can have a discussion but if you are just going to be obstinate on a topic you are not familiar with then its pointless.
