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’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.
You mean we can make FREE ENERGY in our BACKYARD for almost NO Money? This is TERRIBLE!
-LITERALLY Conservatives!
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
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.

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?

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.
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.
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).
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.
Nuclear is slow. Solar is fast.
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.
Nuclear has been slow, for a variety of reasons, but that is about to change.
SMR
Solar is fast now. We need fast now.
You’re not wrong, but it was slow for a good reason.
Solar and wind don’t render entire regions uninhabitable when something goes wrong.
Solar and wind alone can’t run a grid unless there is a significant amount of battery storage.
Okay? That doesn’t have anything to do with the issue.
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.
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.
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.
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.
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.
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 if Republicans weren’t such greedy assholes we’d have been here decades ago
There have been 400 nuclear power plants worldwide for 40 years now. The pre-condition to leave nuclear power plants in the dust is consistent, leisurely growth.
George Harrison knew…“Here comes the Sun and I say it’s all right”.
And they are cooking the animals!
