Nuclear energy is more expensive than renewables, CSIRO report finds::Renewable energy provides the cheapest source of new energy for Australia, a new draft report from the CSIRO and energy market operator has found.

Well the issue with renewable power like wind and solar, is that they are not stable.
Having a battery in order to store the energy and release it when the demand is higher than production is one part of the solution.
But what happens when there wasn’t enough solar and wind to replenish the batteries if those batteries aren’t enough for the demand? Power shortages, which are pretty bad to get.
One of the solutions to this is natural gas for a simple reason : it’s very fast to start generating power or to stop. It’s also not very expensive, at least when there isn’t a war… The co2 equivalent emissions aren’t as high as coal either.
Nuclear power on the other hand is very hard to stop. Having a surplus of power on the grid is also very bad. Some of it could be used to recharge the batteries, but there would be some loss at some point.
The only people writing articles about energy are lobby groups.
There is a propaganda campaign going on in Australia at the moment from the natural gas lobbyists with ads on the TV where they’re pimping themself out as “partners in the transition to renewable energy”.
Also this report is being used by both sides of politics here, one saying it rightfully justifies focusing on renewables and the other claiming it’s being “used unfairly as a weapon” against nuclear energy. Also, the latter is pimping nuclear instead largely because they’re controled by mining companies who have a lot of political influence here oh and we also happen to dig that shit out of the ground.
“It’s a good technology for filling in the gaps around renewables, as well as storage and other methods for making sure that power’s still reliable…”
This does make some sense, like having a diesel generator in your home for the few times a year the power goes out. It’s also useful for shutting up the, “sometimes the wind doesn’t blow and there’s no sun at night” crowd.
Energy generation that works most of the time is more expensive than energy generation that only works some of the time, big surprise. Mason problem is that we need energy all the time and currently can’t store it on a grid level.
There are tons of options for that, mainly energy storage such as batteries, hydro, and green hydrogen. Nuclear is not needed and too expensive among other things.
Hydo is limited in where it can be used and where it can be used if often already is. Batteries can’t yet provide a grid level base load. I don’t know much about green hydrogen but there’s usually a loss of energy when converting from one medium to another.

Look, I’m all for renewable energy, where it makes sense. When I lived in southern California, BLM had so many wildlife restrictions in place, even for off-roading it was kinda nuts. A lot of it dealt with tortoises. Shortly after moving out of state, they started building solar farms all over the place. They’re massive multi dozens to hundreds of acres in size. Many of them in the same areas they got all worked up about for the tortoises…
Generating the power is only a third the battle. Still need to store and distribute that power. Factor in power demands etc.
What I’m trying to say is, as a species we need to get better. This is a good step. However, the power output of a single nuclear plant to the size shouldn’t be overlooked. We should stop fossil fuel reliance. Nuclear is at this point very understood. Yes some bad accidents happened in the past.
It’s worth pointing out too that we aren’t using newer designs as much, which incorporate inherently safe features.
It’s actually ironic. If we built new reactors we could build breeder tractors to generate fuel for them from nuclear waste. This fear mongering of nuclear energy prevents us from reducing that number.
They’re going with older designs for cost reasons. Per the article, you’re taking something that is already not cost effective and proposing to make it even more expensive.
This is basically common knowledge now. CSIRO report pointed to similar conclusions for several years, at least since 2021 when I started to notice.
What is relevant to real life (since Australia probably never will get nukes) is that even assignning system costs only onto VRE, they are still almost the same LCoE in a 90% VRE system. This is again consistent with previous reports.
After Australia pass 100% VRE, exporting green hydrogen in the regional market will probably handle the last remaining flexibility needs. Exporting electricity directly to SE Asia is less likely but still a possibility.
Renewables cannot main grid frequency, which is crucial in America. We transmit AC power. You either accept nuclear or accept no electricity. This is fear mongering propaganda to keep us dependent on fossil fuels because that’s the only other way to maintain grid frequency.
This article also specifically says IN AUSTRALIA. So it isn’t even a comprehensive statement. We need nuclear. Get over it.
I eagerly await all the Nuclear fanboys to explain why this unfairly overestimates the cost of nuclear or was put out by the fossil fuel industry to <checks notes>… make renewables look good.
Let’s not nickel-and-dime the green transition. Nuclear energy has a role to play, and so do renewables. The most urgent thing now is to get as much electricity generation off fossil fuels as possible. Building nuclear power plants is an important part of this, especially in countries like China and India which would otherwise default to burning coal.

Nobody is suggesting we should.

Did you read the article? It only has a role to play if you’re into wasting money.

Can you explain why nuclear would be a part given how long it takes to deploy in comparison to renewables? Nuclear also has a habit of being behind schedule and costing more than projected.
especially in countries like China and India which would otherwise default to burning coal.
The article is about Australia.
It really seems like people can’t get past the fact that while nuclear did have an unfair reputation, it’s just too late to make use of it.
Like yeah, it sucks that people blocked it and we built tons of fossil fuel power instead, but now we just have a better option and we can give up that fight.
Nuclear power and cognitive dissonance. That’s why people are still touting SMRs as the future, except they cost even more than traditional nuclear. Also, they don’t exist.
Okay, but which power sources divert the most wealth to the working class (ie, which one provides more higher paying long term jobs)?
