Yup, it’s all about the economics. Solar + Lithium batteries is cheaper is cheaper than anything else. When Sodium batteries start getting cranked out it’ll be even cheaper.
And they are cooking the animals!
Bullshit!
I’ve seen plenty of conservatives say they’d rather have a loud data center than quiet solar farm near their home.
I don’t understand.
nuclear power is expensive to maintain, plus needs all those expertise. and building the power plant takes like a decade+, and then you have to deal regulatory issues.
solar, you can pratically put that anywhere on the cheap.
headline is clickbait. here’s the only thing it relies on:
According to new reporting by the BBC, photovoltaics will account for 10 percent of the world’s power generation by the end of 2026, a threshold which will see solar energy officially surpass nuclear fission.
Compared to nuclear energy generation — which has stayed largely flat over the past 26 years globally — the publication notes the volume of solar energy being generated has exploded, increasing some 2,700 times over across the same period.
so it’s saying that nuclear usage share is so low that solar will very soon generate more power than it, not that solar panels are now more efficient than nuclear
We could have had this 30 years ago. There have been improvements in the tech and manufacturing, but the main reason for the price drop has been the scale of sales.
We included solar panels and a battery when we built our new house in Tokyo, and even though it’s in a quite shadowy area, I’m surprised how much power we get out of them (even on cloudy days). Switching to an EV now too. It’s an absolute no-brainer.
Serious questions for people not looking to play political whack-a-mole and slapping people around online.
I haven’t taken the time to research - but is the “solar overtaking nuclear” because of the dramatic increase in solar farms? Or primarily from the increase of tech? I imagine an mix of both, but the quantity increase seems to be significant.
Are nuclear plants as efficient as they can be? Or are most of plants decades old with problems from aging?
Can the rise of solar be more person to person investment? Or is it’s increase mostly from huge cap ex from people wanting to own and charge for the energy? Nuke is obviously a huge expense begining to end.
And if Republicans weren’t such greedy assholes we’d have been here decades ago
You mean we can make FREE ENERGY in our BACKYARD for almost NO Money? This is TERRIBLE!
-LITERALLY Conservatives!
Turns out we already have fusion power, it’s just been placed safely 149.6 million km away. The solution to energy independence comes up every morning.
I’m curious, I wonder why something like a large magnifying glass, hasn’t been used to heat up something like a special metal/material or even oil or something, which can somehow be turned into storable energy for the grid 🤷♂️
Other than solar panels? Consumers have to pay for their implementation, with power sold to the grid at such a low rate these days, that for single occupier dwellings, they’re not worth it financially.
I know you are joking, but we have several commercial fusion plants that are in the construction phase.
Now you know why Big Oil is pushing so hard for massive profits. Between renewables and fusion the energy landscape is going to change dramatically.
149.6 million km
how many American hotdogs is that?
You mean a Dyson Sphere right?
All energy comes from the sun except for geothermal which comes from the Earth’s rotational momentum which might as well be the sun because it wouldn’t rotate without something to orbit around.
btw geothermal does not come from the earth’s rotation. it mostly comes from nuclear decay of heavy isotopes in the earth’s interior and the enormous heat capacity of the earth’s interior, which means it’s still warm from the friction heat from when the planet first formed. in other words it’s there since the Earth formed, independent of the sun.
also there’s another (practically accessible) form of energy that comes neither from geothermal nor from the sun: you can pull energy out of the tidal movement that comes from the moon’s changing gravity field as it orbits around our planet. i think that one’s not really being used though because the only way to really utilize it is to build dams across havens and important shipping routes and that interferes with trade, which is considered the more economically valuable activity from the two.
except for geothermal which comes from the Earth’s rotational momentum
emm that is not the source of geothermal energy…
Technically nuclear came from a different star. The sun won’t create those kinds of heavier elements until it burns through its hydrogen and helium fuel to start fusing its way up to lead, and I don’t think it’s massive enough to actually reach the kind of supernova collapse required to smash lesser elements together into heavier elements than that in any significant amount. So technically, fission is the only the form of energy that isn’t based on solar. It’s just the still-cooling-embers leftover from someone else’s dying star, a whole bunch of billions of years ago. I guess you could say the sun’s gravity at least attracted it all into this general vicinity though, at least until the Earth’s own gravity started pulling its own weight.
Didn’t the molten core also originate in some way from the sun?
While I consider myself pro nuclear, there is something that gets forgotten everytime this conversation comes up.
Nuclear produces waste, which is mentioned often but it is usually responded by pointing out that it could be recycled and the worse to be buried.
Here is what people miss:
Are all our nuclear waste handled correctly today? If not then why should we imply that they will be in the future.
The problem with nuclear isn’t that the waste is impossible to handle, it’s that humans are too short sighted to follow through with it.
And imo that’s a very valid argument on why we should use solar as much as we can.
Being pro-nuclear was a very valid position up until a few years ago. Now solar has gotten so cheap that there is practically no reason to do it except to protect yourself against US imperialism.
Nuclear reactors could still be useful in things like the mass production of hydrogen through steam electrolysis or even using fancy stuff like thermochemical reactions.
I know China is planning on building the world’s first nuclear reactor integrated into an industrial area for the production of very hot steam.
Solar still has some huge problems when it comes to seasonality and day/night cycle. You either need massive battery build out or some other form of energy to handle base loads and/or offset when solar isn’t producing enough.
Not saying solar isn’t part of the future, but we literally can’t just rely on solar.
Solar panels have become more than ten times cheaper than they were a decade ago. They are easily able to gather half the energy of what they did a decade ago in the summer now in the winter.
So even in the winter solar is twice as price efficient.
Yes there is downtime but solar is a fast and cheap way to replace most electricity cost. Then the rest can be fixed with nuclear in 20 years. We need clean cheap energy now and we can mostly get it.
I’m not talking about price, I’m talking about generation.
I have solar panels, they are great. However, I get too much energy in the summer, not nearly enough in the winter, and no power at night. Since I’m on a grid that doesn’t matter too much for me, but highlights some of the issues.
Even if I installed a battery, I’d end up with extra power in the summer and not enough in the winter. Which just highlights the discrepancy in production. Batteries obviously help solve this, but some mixture of wind/nuclear/other is needed.
This isn’t a problem at City scales and beyond. You just can’t buy a bunch of nazi batteries so there isn’t a corp greasing politicians to build it.
Battery tech is getting super good though, and the materials are recyclable. If solar becomes cheap enough we could even store it in creative (but less efficient) batteries like lake batteries or weight batteries and the like.
I had heard of lake batteries over the years, but never a weight battery. Thank you for teaching me something new today!
You know what else I haven’t heard of in a while? Thermal solar, where they use a parabolic mirror array to concentrate the sun onto a small tube full of water pushing a steam turbine. Even the plain steam could be used for heating and more. Steam can absolutely be concentrated under pressure (more of a capacitor than a battery since the temp won’t hold, but it does provide stability). The steampunk future from comic books is at our finger tips only we will generate the steam using the sun rather than big factories of iron and steel.
Nuclear, both fission and fusion (which will never happen anyway) are relics of an era of cheap fossil fuels and relative world order.
Solar electricity is viable at scale but also indicates a change in our species’ living arrangements on this planet.
That’s an interesting way to look at it. If it’s not just about the power and the cost, there are actually a lot of other factors that we have glossed over.
Solar is cooperative and local while nuclear necessitates centralization. In a nuclear future, large nuclear generating corporations are the sellers and we are the buyers. In a solar future, we pool and exchange our power depending on current production ability and current electric need… comrade.
We are started to build the first commercial fusion plants now. You may want to update your rhetoric.
You may want to update your physics, engineering, and reality.
You can remain ignorant, it is up to you. Cheers!
I look forward to seeing them produce energy in a short 20 years from now.
You should read up on the topic, I know I was surprised, the breakthroughs have recently happened. Now it is just permitting and building. Obviously there will still be issues, but there is little question to the reality now.
I’ve read of smaller reactors that should speed up prototyping, but nothing about actual net positive energy production. That’s still far away.
This happened a long time ago. Prototyping is over. I was very skeptical as well up until they figured out a practical reactor design and are in the process of building and permitting several commercial plants around the world.
No, there won’t. You sound like you’ve never heard of a scam. Here’s one:
https://en.wikipedia.org/wiki/Solaren
Just, no.
Living in denial as they are building commercial plants. Looks like Big Oil propaganda got you.
You do realize that you can support multiple things? You don’t have to be antinuclear to be pro-solar.
You need to choose a thing to build there is not unlimited budget.
While I consider myself pro nuclear, there is something that gets forgotten everytime this conversation comes up.
The problem with nuclear isn’t that the waste is impossible to handle, it’s that humans are too short sighted to follow through with it.
Thats not even the biggest problem with nuclear power as the waste angle, at scale, will hit us decades in the future. The more urgent problem hitting us now on even on existing deployed nuclear plants is cooling water.
The byproduct of nuclear power generation is lots AND LOTS of waste heat. You have to get rid of this every second to continue to produce electricity. This is why nuclear power plants are typically built next to a large body of water. However, with reduced water supplies in reseviors theres less water to use for cooling nuclear plants. A double whammy is with climate change increasing temperatures, the water that remains is already hotter than it was, meaning it can carry away even less heat.
If a plant can’t get rid of its heat it needs to curtail (reduce) electricity production. This isn’t just theoretical. Its happening now in 2026 to existing power plants:
-
Hungary - Aug 2026 Hungary plans to shut down only nuclear power plant amid drought
-
Romania - Aug 2026 Nuclear power plants are being shut down as Europe’s drought becomes an energy crisis
-
France & Switzerland - Aug 2026 Droughts cause nuclear power plants in Europe to reduce output
At the time when Europe was experiencing its worst heatwave is recorded history, many European reactors had to be turned down or off. 2026 isn’t the first time this has happened either, you can go back in the last 5 years or so and see many reports of nuclear plant curtailment because of lack of cooling capacity (cool water).
When we know global temperature are rising, it looks like this will just get worse. How can we say nuclear is the future when the conditions for it working well are already declining?
Fuck, that’s a terrifying thought. Bring on the panic attacks! Yay!

The fact is that humans are just not well equipt to deal with problems beyond human scales.
We’re not good at accurately assessing risks beyond human time scales and we’re not good correctly prioritizing action when the benefit is beyond human time scales.
Big Oil predicted global warming pretty spot on, they just fought it and hid the findings instead.
To some extent I think we’ve gotten pretty good at long term predictions on things like this, but no one wants to hear it.
Global warming is a great example of how terrible we are at dialing in the correct priority for issues beyond human scales.
When some humans worked out it was coming, nothing happened - the opposite of nothing. As more humans became aware, more effort was put into styming efforts than actually doing anything.
Even now, as the effects are near-universally understood, present, and killing people - still we fail to act on the threat with anything like an appropriate level of seriousness.
To the disposal argument i like to ask; are we handling our waste from burning fossil fuels well?
Is run away climate change “doing it well”?
Would you rather your waste be buried in the ground or pumped into the atmosphere?
Containing the waste and burying it in the ground is the default for nuclear, meanwhile doing the same for CO2 is very challenging and it may never be viable.
But we are comparing solar to nuclear.
Being better than fossil fuels is a pretty low bar.
And yes better nuclear than oil but the whole thing about nuclear is that it has a very delayed start time, so the argument of needing it ASAP supports solar if anything.
We also have limited potential stores of uranium. When Chinese reactors all get on line, maybe 40 years left.
fire it into space futurama style
Would you trust a SpaceX rocket with radioactive waste?
IMHO another big issue with nuclear is concentration of power. nuclear is quite stable, but not always and when it fails you suddenly loose a huge bunch of production that becomes hard to replace. (and Im not even getting into safety here)
France had to deal with a lot of issues just this year, with around 20% of their nuclear plants unoperative, which increased prices dramatically.
Solar is mostly distributed by design (and need) and failures are smaller
A hailstorm wiped out 350mW of solar in Texas in 2024. But, they learned that the angle of panels was critical to avoid damage and now they have a hail storm mode that increases the angle to protect the panels.
Not sure if panels can survive hurricanes, certainly not tornados.
350mW
Maybe they should keep some AA batteries around just in case another hailstorm hits.
AAA might be more portable though Texas might loose them in a strong gust of wind
Agreed. Are we seriously forecasting 5000 years of stable, deep, under-mountain storage. For all those years, waste storage is a prime target for contaminating locales.
The other quality argument I’ve heard from Lemmy, is that the security requirements for nuclear plants are essential and costly, due to plants being a similar target for creating contamination.
Essentially, nuclear power is a fascist tech, due to the centralised, militaristic, security apparatus required for the life of the plant and waste.
nuclear power is a fascist tech
Calm down, Francis.
Guess which single country is making all the PV panels?
Wake me up when it beats fossils:
2021?
Not quite the same format, but 2025. And not so much transition as addition. On top of still increasing coal and gas.
A lot of that coal is temporary in China before they get their reactors on line. They have 43 under construction.
Averaging nuclear over the entire world really doesn’t give it a fair shake, since there are many jurisdictions that won’t build nuclear capacity for political and societal-preference reasons, rather than technical ones. Where I am, the percentage of electricity supplied by nuclear power plants is more than five times what’s supplied by solar and wind combined, and we’re doing just fine (and building out more nuclear in addition to more renewables).
since there are many jurisdictions that won’t build nuclear capacity for political and societal-preference reasons, rather than technical ones
Most jurisdictions aren’t allowed to build nuclear, for nonproliferation reasons. That’s because nuclear technology can be used for nefarious purposes, and requires a highly functioning security apparatus in order to enforce safety requirements. So as a society we’ve tried to keep it out of the hands of those that the great powers have decided can’t be trusted with the tech.
Which then raises the uncomfortable question of whether we should trust ourselves, the current great powers, with this technology? If we plan out a 50-year useful life for a power plant, do we trust that the governments and companies operating that plant (and its supply chains and its waste management) will still be doing things safely in 50 years?
These days, I’m less sure.
Nuclear is slow. Solar is fast.
Nuclear has been slow, for a variety of reasons, but that is about to change.
SMR
Modular reactors are fast. Ontario will have three online in 2 years.
You can have a solar panel up and running in like an hour.
Solar is still faster
Solar is fast and getting better continuously. The new battery technologies like Sodium Ion are eliminating the downsides to it. We just need a big battery shack on every block with safe sodium battery storage and solar panels on all the house roofs.
I think the main advantage is how much easier and cheaper solar is than nuclear. Also apparently nuclear will have diminishing returns as the earth warms up, due to cooling issues.
Also with things like balcony solar, you can easily get a distributed power network.
That being said, nuclear is also great. Especially the newer powerplants behind produce very little waste material.
In UK in 2010, 10 new nuclear plants were announced. Since then 5 older plants have been shut leaving us with 5 active. 1 of the 10 new ones started construction and it’s massively over budget and delayed.
In the same time we’ve added about 20GW of solar.
New nuclear plants take like 10 years to build, and need to plan out a 50+ year useful life in order to be worth the up-front construction costs.
I wonder what the state of energy production in 2075 will be, where a nuclear power plant designed in 2025 and completed in 2035 will still have 10 years in order to break even on cost, competing with whatever the state of the art is on generation in 2075. Fusion? Widespread solar+wind+geothermal+batteries? Something we haven’t even dreamed of?
That’s why I’m skeptical of nuclear fission these days. It locks us in too long.
I’m all in on solar for most places.
Sure it uses a bit more land, but it makes no noise, no pollution, there’s zero risk of an accident, no targets for terrorism and your grid isn’t completely shut down if it is somehow turned offline.
You don’t depend on others for your own resilience. No need for oil, gas or uranium.
Unless you live in the high northern latitudes, there is almost no reason to not be building a durable and resilient battery-renewable grid
btw the reason why denmark and germany are building so many wind turbines is mostly because they’re so far north.
Solar should be in every parking lot and the median of every highway as the baseline, already space we’ve developed and can (more) easily add to.
Solar and wind don’t render entire regions uninhabitable when something goes wrong.
Its possible to build reactors that don’t fail spectacularly. Just look at penslyvania with the three mile island nuclear plant or hell you could even look at fukushima. People still live around those locations.
edit: Build out more solar too because that is a great way to generate power but don’t snub other things just because they aren’t “perfect” from your perspective.
Solar and wind alone can’t run a grid unless there is a significant amount of battery storage.
Sorry if this is an uninformed question, but can’t we just pump infinity liters of water uphill?
Sure if you have the infrastructure and topography to do so. But this adds to the cost.
The problem is everyone always compares solar alone to nuclear in this comparison it looks really good. However when you include the cost of storage, it doesn’t look as good.
The analyses I’ve seen suggest that we will need to build at least some nuclear to achieve the fastest and cheapest decarbonization.
Okay? That doesn’t have anything to do with the issue.
