Why go nuclear when renewable is so much cheaper, safer, future proof and less centralised?
Don’t get me wrong. Nuclear is better than coal and gas but it will not safe our way of life.
Just like the electric car is here to preserve the car industry not the planet, nuclear energy is still here to preserve the big energy players, not our environment.
Renewable instead of nuclear, but nuclear instead of coal.
We need a mix. Centralization isn’t the biggest problem. Literally anything we can do to reduce emissions is worth doing, and we won’t be going 100% on anything, so best to get started on the long term projects now so that we can stop turning on new plants based on combustion.
The main problem with nuclear power plants isn’t the radiation or the waste or the risk of accident. It’s that they cost so damn much they’re rarely profitable, especially in open electricity markets. 70-80% of the cost of the electricity is building the plant, and without low interest rates and a guaranteed rate when finished it doesn’t make economic sense to build them.
The latest nuclear plant in the US is in Georgia and is $17 billion over budget and seven years later than expected.
The cost of continued fossil fuel use is far higher.
rarely profitable
Profit should not be the motivation of preventing our climate disaster from getting worse. If the private sector isn’t able to handle it, then the government needs to do so itself.
And besides, the only reason fossil fuels are so competitive is because we are dumping billions of dollars in subsidies for them. Those subsidies should instead go towards things that aren’t killing the planet.
Would it be better to dump billions into nuclear power plants that won’t come online for a decade at least, or to dump billions into renewables that can be online and reducing emissions in under a year?
We should worldwide be putting trillions into both. Renewables should be first priority, but not all locations have good solar, wind, and battery options.
You cannot run the entire grid on entirely renewable. We physically don’t have enough lithium in the world to make the batteries for it, and even if you don’t use lithium there would be untold ecological destruction to extract the rare earths.
Renewable and hydroelectric is a solution but not viable everywhere and hydro also causes massive ecological destruction
If we started building nuclear powerplants right now it would take 10-20 years before they’re even online. That’s 10-20 years worth of technology improvements that could make it obsolete, especially if we don’t pin our hopes on nuclear baseload and start building a grid that can be 100% renewable.
And that’s not even mentioning the truly massive budget overruns. Or the environmental impact of mining and refining fuel.
And you would be running 10-20 years of gas and coal power plants in addition to the renewables if you’re not in a suitable area for hydro because suitable grid scale energy storage solutions literally don’t exist. Maybe they will in 10-20 years, but would you bet on a maybe or go with nuclear which we know will work as a baseload?
Nuclear plants are immensely profitable, just not on time scales politicians are interested in. You’re deep in the red for 10-20 years and then after that it prints money
So after 10-20 years of construction and cost overruns and 10-20 years of operating at a loss you start making money.
And that’s assuming electricity rates don’t drop in that time. Which they are as renewables get deployed more and more because they don’t go 100% over budget in time and money.
If we get started building nuclear power plants now, how much will storage and transmission tech improve before they’re even completed, let alone profitable?
It’s not 10-20 years of construction AND 10-20 years at a loss, it’s 10-20 years of construction at a loss. Not great, but up to 40 years as you suggest sounds a lot worse because it’s a misrepresentation.
We can and should be doing both. Use the money our governments are giving to fossil fuels in subsidies. $7 trillion PER YEAR (that’s 11 million every minute) in public subsidies go to fossil fuels. Channel that to nuclear and renewables and there’s more than enough to decarbonise the grids with both short- and long-term solutions.
What we definitely should not be doing is closing perfectly working nuclear power plants.
Power generation and power use need to be synchronous. Renewables generate power at rates outside of our control. In order to smooth out that generation and bring a level of control back to power distribution we would need a place to store all the energy. Our current methods are not dense enough and are extremely disruptive/damaging to the environment. Nuclear gives us a steady and predictable base level of generation that we can control. Which would make it so we don’t need to pump vast quantities of water into massive manmade reservoirs or build obnoxiously large batteries.
Nuclear (with the exception of France because they’re special) is limited to being a base load as you alluded, but power demand varies throughout the day. Nuclear can’t vary on a 24 hour scale to follow the load so we need renewables and energy storage or hydroelectric to make up the difference. That’s what “nuclear OR renewables” misses
Because it gets dark and the wind stops blowing and industry still operates when those things happen. Nuclear is not a forever solution, but a necessary stop-gap.
And where do you think all the materials for that come from? Eind turbines, solar panels and batteries require huge amounts of (rare) earth materials that need to be dug up in very -let’s say ugly- mines… lithium for example, is now the core component for most of our batteries and lithium mines are polluting as hell. If we want to have all the lithium we need for all of our storage capacity, well need to destroy beautiful places like the Atacama desert because if we don’t we won’t have enough lithium.
Storage technology isn’t there yet. Nuclear is. The only viable approach is “all of the above.” Anything less is foolishness and oil industry propaganda.
The same people who run the oil companies also run nuclear plants, billionaires love a monopoly but what they hate is local communities being able to own and run solar farms and wind turbines, they hate the idea of someone that isn’t them being able to spend a million making a profitable offshore wind farm or a raised water energy storage facility – more than anything they hate the thought of houses and businesses having PV on the roof and being able to detach evenb just in part from the mechanisms owned by them.
50 yeas ago people couldn’t think of a future without fossile fuel. 100 years ago people thought ships would run on coal for eternity and 200 years ago or in fact up until WW2 horses did most of the work when it came to transportation.
Things change fast. Stagnation of technology is not the norm.
It’s not actually required at all though, thats all FUD from the big energy monopoly that hate anything that can be owned and run by people that aren’t them - there are endless options for making a stable grid using renewables and they’re all considerably cheaper, quicker to make and a lot more resilient.
Nuclear gets pushed so hard because it protects the billionaires monopoly that’s the only reason.
Yeah, the cost is the real downside to Nuclear. However, for every Nuclear plant running, that’s a lot of batteries it other energy storage that don’t have to be built today in order to have clean energy. Because even if we were utilizing nuclear like we should, we would still need to be building a shit ton of batteries to keep the cost of energy coming down.
The cost of electricity dropping is bad news for nuclear power plants because they’ll be even less profitable when they’re finished. Especially since they take decades to construct, during which time renewables and storage become even cheaper.
And we’ll still need a way to store power from renewables when they overproduce.
You don’t need to imagine a future without nuclear in the mix - there are plenty of places doing fine with renewables and without coal or nuclear right now.
For example South Australia - no coal since 2016, no nuclear ever, runs mostly on a mix of renewables - solar and wind with batteries and transient gas for in-fill.
Edit: thanks to whoever downvoted my verified statement of fact (see below)
Weird argument. “It’s a place bigger than a bunch of EU countries put together but it’s not a country so I’m going to use other places that aren’t South Australia to counter your point which was about South Australia”
Wind and Solar are “renewable” to a certain scale. If you dump gigantic wind farm in the middle of a jet stream, for example, you can impact downstream climate cycles.
A big problem with solar and wind is that they are not as reliable as nuclear. In a worst-kaas scenario neither will produce energy because there is no sun or wind and there is no way to store enough electricity for these moments. Therefore we need a constant source that creates electricity for those moments. Of course, we do also need renewables, but nuclear is essential because it is reliable.
Scalability problems. We need to make as many solar wind and battery installations as we can, but there’s only so much production and installation capacity. And eventually we’ll run short on materials, especially for batteries. Nuclear uses a different system, so we can scale that even as we have issues with other systems.
For what I’ve read, it’s beats nuclear tech exists and is ready to be built at scale now. Renewables are intermittent in nature and need energy storage to work at scale.
We don’t have the tech for a grid wide energy storage.
Why go nuclear when renewable is so much cheaper, safer, future proof and less centralised?

Even if it takes 2 decades to get a new plant going, it’s a nuclear plant’s worth of fossil fuels we don’t need any more, and therefore worth doing.
If it isn’t fossil fuels, it’s automatically better.
The main problem with nuclear power plants isn’t the radiation or the waste or the risk of accident. It’s that they cost so damn much they’re rarely profitable, especially in open electricity markets. 70-80% of the cost of the electricity is building the plant, and without low interest rates and a guaranteed rate when finished it doesn’t make economic sense to build them.

That’s your opinion. I think funding nuclear is just burning money and wasting time we don’t have.
You cannot run the entire grid on entirely renewable. We physically don’t have enough lithium in the world to make the batteries for it, and even if you don’t use lithium there would be untold ecological destruction to extract the rare earths.

There are urgent needs we can’t wait 50 years for.

The cost of electricity dropping is bad news for nuclear power plants because they’ll be even less profitable when they’re finished. Especially since they take decades to construct, during which time renewables and storage become even cheaper.
And we’ll still need a way to store power from renewables when they overproduce.
Don’t forget nuclear waste that is just building up forever with nothing to do with it.
I can’t imagine a future without solar, wind, and nuclear power.
not unless we find out we are wrong about thermodynamics.
You don’t need to imagine a future without nuclear in the mix - there are plenty of places doing fine with renewables and without coal or nuclear right now.
which country?
For example South Australia - no coal since 2016, no nuclear ever, runs mostly on a mix of renewables - solar and wind with batteries and transient gas for in-fill.
Edit: thanks to whoever downvoted my verified statement of fact (see below)
never heard of that country.

lol im not playing this shell game.
Wind and Solar are “renewable” to a certain scale. If you dump gigantic wind farm in the middle of a jet stream, for example, you can impact downstream climate cycles.
that’s why we could be aware of all the externalities.
solar could be deployed on the ocean but that will certainly lower sea temperatures.
let’s terrafirm intentionally rather than just accidentally.
A big problem with solar and wind is that they are not as reliable as nuclear. In a worst-kaas scenario neither will produce energy because there is no sun or wind and there is no way to store enough electricity for these moments. Therefore we need a constant source that creates electricity for those moments. Of course, we do also need renewables, but nuclear is essential because it is reliable.
So it’s more nuclear vs renewables and a ton of batteries. (Or other storage options)
Scalability problems. We need to make as many solar wind and battery installations as we can, but there’s only so much production and installation capacity.
