This diagram shows the LCOE (levelized cost of electricity) for various technologies - i.e. how much does one kWh of electricity cost if you divide the total number of generated kWh by the total cost of the power plant.
“utility-scale solar” means large-scale flat-area solar parks
But will Fusion ever be cheaper than solar?
I doubt it; It’s not only about technology costs but also about advantages like decentralization. If you can generate your own electricity in your own back-yard, you’re much more independent than if you’re dependent on large-scale fusion power. Because that will necessarily be very large-scale and centralized because nobody can set up a fusion reactor in their own back yard.
but isnt it being centralized being the point? I have the (probably not so rare) tin foil theory that big energy spends a lot of money to dampen solar and other decentralized power generation. As a politician you have to ask yourself, do I get nice packages from big energy for not looking so closely when another forest is turned into a hole or do I hope that 20000 random people try to bribe me for something. In terms of money gain for a few big power plant is double plus good. Boring solar might be better for all of us, the rest, but not for the guys calling the shots. This all assumes of course that there is no empathy at all in the local legislation
That’s why I always want to crowdsource corruption. Everybody who wants something gives 3 Euro/Dollar/Whatever and we just carry those cash suitcases to the morons in charge. What big companies can do, we can do!
I haven’t looked into it but isn’t the problem that bribing and corruption, as we general think of it, is not common anymore. They’ve gotten creative.
They don’t hand you cash. they form super PACs that are legislative black holes so “people that align with you politically” can use that money to help you run, or your family member is hired as a VP in a company where they do nothing but get millions in stock options. They can also you can also get paid for talks, meetings, lectures in exotic locations. Hell, Clarence the supreme court judge gets stuff all the time from his billionaire friend. here’s John Oliver.
Well, I just give them a contract for a speech of two minutes, worth 3 million, I guess. Even those politicians will see the appeal in just receiving plain ol’ money instead of jumping through all those hoops.
I really hate how so many of these articles feel like they need to dumb it down with this “artificial sun” imagery. It feels so condescending. I’d rather learn more about the latest progress with nuclear fusion
Most Americans read at or below a 6th grade level
So we hear. But the world is not America and this is a British newspaper.
To be fair I don’t think literacy rates in the UK blow the US out of the water or anything.
I check on this. So first thing I found, literacy rates and average reading age are different things. Literacy rate, able to read at all, is clearly tracked and both countries are like 99%. Reading age seams really mushy. If you can get some numbers, please share!
Oh I couldn’t get any hard data on reading age for the UK. Search engines are trash now.
Just figured out the apples to apples term to search is “functionally illiterate”
From a quick glance it seems to be about 18% (UK) vs 21% for the US. So as I expected, better but not anything to write home about.

You mean you don’t just trust the AI summaries?
18% or 21% sounds like a lot of people. Not an easy problem. :-(
Meanwhile USA is stealing Venezuelan oil. Good job everbody. 👍
Just a few years ago US labs were the first to generate more power than they put into a fusion reactor, it was one of the most important breakthroughs to date in fusion.
Even under the shitheap Trump, the US is continuing to research into fusion and building stellarators such as Infinity 1 in Tennessee.
Europe likewise is leading breakthroughs such as with Wendelstein 7-X stellarator in Germany lasting for 43 seconds. This is being improved with the new Proxima Alpha stellarator being built.
China’s EAST reactor had a breakthrough when they achieved 1,000 seconds last year. While Europes recent ITER tokamak should be achieving its first plasma in the coming years.
Fusion is a global effort, and scientists are benefiting from the works being put in elsewhere. Stellarators and Tokamak are both breaking new grounds each year, and each has their own pros and cons.
Don’t fall for any propaganda trying to claim anyone is “winning”.
These comment sections can be a place of puerility and defeatism. Thanks for being the difference.
it was one of the most important breakthroughs to date in fusion
What ? It was not really. Here’s a physicist discussing why.
https://dothemath.ucsd.edu/2023/08/fusion-foolery/
In the end, the NIF fusion accomplishment might be called a stunt. Stunts explore what we can do (often after an insane amount of preparation, practice, and failure), rather than what’s practical. Stunts hide the pains and present an appearance of ease and grace, but it’s a show.
The “more energy out than laser energy in” equation masks several fundamental problems. NIF’s doped glass lasers have an efficiency of about 0.5 percent, meaning that they would have sucked in roughly 400 megajoules of energy from the grid in order to produce the 2.1 megajoules of light energy…
To be fair the hype machine was from the press not the scientists
Let’s pause to say: well done! Honestly. No sarcasm. What they did was ridiculously hard, and it finally worked after more than a decade of trying. They actually produced a significant number of fusion events! There’s no faking that, and I’d like to see you try. So let’s be clear that I’m not knocking the accomplishment in itself. My major beef is how we interpret the implications for society.
Stunts also draw attention to stuff. Its yet to be seen if its a net positive but it did help me get up to speed on the current state of fusion technology.
oil, coal and nuclear are clearly not winning.
we could solve the worlds energy problems today but they’d never be applied simply because oil exists. its literally why the US just attacked venezuela. They could have built another reactor or windmills or whatever the fuck else they feel they need if energy was the reason. but energy has nothing to do with energy and all to do with being a natural monopoly that’s making a small group of people quite wealthy.
Yes but those are not fusion. Fusion is the ‘holy-grail’ of energy technology. It is a long term goal that we must work towards. It’s a problem of science.
For now renewables are the cheapest, quickest, and best method we have. They should be receiving all the money wasted on those 3 methods you’ve mentioned above. That’s a problem of politics.
We easily have the means to achieve both, we are hamstrung by shortsighted corporate interests and yes this applies to China as well.
