It takes time for statistical agencies to compile reports. I haven't yet found reports covering the growth in renewable generation (actual terawatt hours) for all of 2025. But this covers 3 quarters of the year:
In the first three quarters of 2025, solar generation rose by 498 TWh (+31%) and already surpassed the total solar output in all of 2024. Wind generation grew by 137 TWh (+7.6%). Together, they added 635 TWh, outpacing the rise in global electricity demand of 603 TWh (+2.7%).
The problem is in power transmission. Transmission fee is a big part of the cost. Anything helping for at home generation should be encouraged.
Right now plug in solar is starting to appear. It is big in Germany. Utah has passed a law to cut the red tapes to allow home owners to install plug in solar themselves. More states should follow.
>At the global level, 2025 also saw a sharp rebound in non-renewable additions, which nearly doubled compared to 2024," IRENA noted. China led that drive, with 100 GW of non-renewable capacity added last year, most of which was coal.
Why is China adding so many new generation plants powered by coal? On this and other forums, I see claims all the time that solar is cheaper than coal. As the world's leading producer of solar panels, you would think that they would utilize it even more if those claims are true.
Is it just the need for power when the sun is not shining? Or is it something else?
My understanding is that China is planning to build a coal-backed renewable grid. Renewables, including storage, will provide the majority of the electricity generation, and then coal will step in when renewables aren't available. This involves building modern coal plants that can be spun up and down as needed, and then paying them not to generate. This is why actual emissions have plateaued and dropped, even as new coal capacity comes online.
We are (or were) doing something similar in the US, just using natural gas as the fuel rather than coal.
Wait this is actually amazing, I had no idea it was that high. I canât even believe what the US admin is doing, this is clearly the winning technology.
Installed capacity is a misleading number. If you assessed the trucking industry by simply sum-ing the rated capacity of all the hardware you'd be rightfully laughed and and called a liar on the basis of all the times the trucks are empty and all the trucks that run out of volume before weight. Renewables is a similar situation.
Some panel in a solar farm in Canada is not gonna see the conditions that let it produce rated capacity nearly as often as one in Arizona. So the guy in Canada installs more capacity to get the same power. Meanwhile the guy in Arizona doesn't have enough copper leading out of his site to handle the power he could produce at peak on the best days, because he over-provisioned too, in order to be able to produce a given amount earlier/later in the day. The actual generation hardware is so cheap that this is just the sensible way to deploy renewables, but it makes for stupid misleading numbers.
Legacy power generation has much different numbers and isn't subject to the whims of the weather so installed capacity is a number that means something in that context.

OK, but what if someone looked at the rated capacity of all trucks and noted that in the last 5 years it went up by 24%, 22%, 28%, 54%, and 45%? That would strongly suggest that the amount trucks actually being used is growing rapidly because people aren't going to be buying new trucks unless they have to.
This is a common rebuttal, but not grounded in reality. Even assuming ~20% capacity factor for "apples to apples" comparison to legacy thermal and nuclear, solar and batteries are the cheapest form of power to install. Current geopolitical events spiking LNG costs make the math even more favorable towards renewables.
> Legacy power generation has much different numbers and isn't subject to the whims of the weather so installed capacity is a number that means something in that context.
Legacy power is ridiculously expensive in comparison. Who will invest in fossil gas generation when ~20% of LNG exports have been taken offline for the next 3-5 years?
Fossil fuels are over, it's just how fast we get to "done." Enough sunlight falls on the Earth in 30-60 minutes to power humanity for a year. Solar PV and battery manufacturing continues to spool up, and year by year, more fossil generation is pushed out.
California is routinely operating at 80% renewables, 90% low carbon generation during daylight hours as they work towards installing battery storage to replace their fossil generation (~52GW target by 2045), for example, while having plans for 10s of GWs of additional solar to come online over the next decade.
> This is a common rebuttal, but not grounded in reality. Even assuming ~20% capacity factor for "apples to apples" comparison to legacy thermal and nuclear, solar and batteries are the cheapest form of power to install.
I looked it up because I was curious, according to Wikipedia average PV capacity factor is 25 % in USA, 10 % in the UK or Germany.
Nuclear has 88 % capacity factor worldwide. Meaning to replace 1 GW of nuclear installed capacity you need 8.8 GW of PV installed capacity in Germany or 3.5 GW of PV installed capacity in US.
Which might still be economically worth it, I don't know. But it is a number that surprised it.
It takes ~10 years to build a new nuclear generator from breaking ground to first kw to the grid, and tens of billions of dollars or euros. Germany deploys ~2GW/month of solar, the US ~4-5GW/month. Total global nuclear generation capacity is ~380GW as of this comment. At current global solar PV deployment rates, even assuming capacity factor delta between solar and nuclear, you could replace total global nuclear generation with ~18 months of solar PV deployment.
Yes, the biggest advantage of solar and wind is that they can be built as many small projects, instead of few gigaprojects we seem to have lost the ability to execute in the West.
Modern grids favour flexibility over fixed baseload generation (like nuclear) though. When you turn off a nuclear power plant its operating costs basically stay the same, which is horrible when you could cover your whole consumption with basically free solar/wind.
France had to nationalize EDF due to the exorbitant cost of their nuclear fleet, and they cannot get a reactor built within reasonable capital costs. Spain plans to deprecate their remaining nuclear for renewables for similar reasons. California will achieve a low carbon generation profile for far cheaper than it cost France (refer to the Lazard LCOE data product I've cited in my other comment in this thread).
Spainâs Nuclear Shutdown Set to Test Renewables Success Story - https://www.bloomberg.com/news/articles/2025-04-11/spain-s-n... | https://archive.today/4fB7K - April 11th, 2025 (âSpain is a postcard, a glimpse into the future where youâre not going to need baseload generators from 8am to 5pmâ with solar and wind providing all of the gridâs needs during that time, said Kesavarthiniy Savarimuthu, a European power markets analyst with BloombergNEF. Still, she said, there is a reasonable chance this goal may take longer than expected and âextending the life of the nuclear fleet can prove as an insurance for these delays.â) (My note: As of this comment, Spain has 7.12GW of nuclear generation capacity per ree.es, and assuming ~2GW/month deployment rate seen in Germany, could replace this capacity with solar and batteries in ~17 months; per Electricity Maps, only 15.45% of Spain's electrical generation over the last twelve months has been sourced from this nuclear: https://app.electricitymaps.com/map/zone/ES/12mo/monthly)
The reason EDF had to be nationalized is because the government used the company as a "price shield" to protect consumer against energy price rise on the European market in 2022 with a mechanism named TRV (Tarif RĂŠgulĂŠ vente). That digged up EDF dept tremendously.
> Spain plans to deprecate their remaining nuclear for renewables for similar reasons
Span deprecated their nuclear government because their current Socialist government is aligned with Ecologists that are, like everywhere in Europe, antinuclear.
Additionally, the lack of spinning generator in Spain is currently partially what caused the Blackout in Spain in 2025 due to a lack of inertia in the system.
> EDF fleet upkeep will cost over 100 billion euros by 2035, court of auditors says
This is over 25 years and will prolong-ate the lifetime of the 56 reactors by 20 more years. These produce 70% of the country need in electricity.
In comparison, the German energiewende cost 400 billions for 37% of electricity of 2025 produced by solar and wind. With production medium that will need to be entirely renewed in 20 years.
> California will achieve a low carbon generation profile for far cheaper than it cost France (refer to the Lazard LCOE
That is also wrong.
Because LCOE calculation does not take into consideration the price of the grid consolidating necessary for renewable nor the necessity of backup generation in case of dunkleflaute.
I didn't say they weren't cheap. I said you were being misleading. I'm not rebutting your thesis. I'm rebutting your defense of it.
They're so cheap they get over-provisioned on purpose. Can you imagine some guy speci'ng switchgear and transmission lines for a coal or gas plant that can't handle the plant running full tilt? Yeah me either. But that's exactly how it's done for renewables because that's where the sweet spot of cost-benifit is.
A dozen 10mw turbines might be fed through 100mw of transmission hardware. They can never produce their rated 120mw because liquid copper would happen if they did. But they were intentionally provisioned that way so that based on weather patterns and whatnot they'd be able to expect say 80mw a certain number of days per year.
There are untold numbers of renewable installations out there that cannot supply their nameplate capacity to the grid in such a manner.
There is nothing wrong with over provisioning cheap renewable power generation when it is economically superior to building fossil assets that will end up stranded. As long as grid demand is met and it is cheaper to build renewables and batteries to do it, it will be done, and that is the path we're on.
If gas plants cannot economically compete, they will not be built or fired. And the evidence shows they cannot compete, regardless of their competing capacity factor and dispatchability.
Do you have some links to how someone scaled up storage? I know that scaling up solar is easy, but I don't know of any nation that build significant storage.
You are still arguing against a strawman. Cucumber3732842 is just saying that nameplate capacity is a systematically flawed metric when comparing renewable generation, because their capacity factor is consistently lower than for conventional plants.
A better metric would simply be annual production, where we're in the ~30% range globally (https://ourworldindata.org/grapher/share-electricity-renewab...). Even that comparison portraits renewables very favorably, because dispatchable power is easier to handle than the same output from intermittent sources.
If you look beyond electricity (heating/total primary energy use) the picture gets even worse.
This is not an argument against renewables, this is against premature cheering and misleading use of numbers.
I think you misunderstand. We are cheering trajectories, not the point in time. Renewables and storage will continue to be deployed, fossil fuels will remain expensive, and build outs will continue over the next decade or two. If these trajectories hold, and growth rates continue to grow for clean energy deployments, what happens? The outcome is obvious, is it not?
Of course, there is nuance, but the facts are that in the next 10-20 years, renewables and storage will have destroyed demand for fossil fuels for electrical generation. That's progress. We might go faster or slower, depending on policy and other factors, but this is the trajectory we are currently on, based on the data presented in this piece.
The Economist wrote a piece explaining this, if that is helpful:
> To call solar powerâs rise exponential is not hyperbole, but a statement of fact. Installed solar capacity doubles roughly every three years, and so grows ten-fold each decade. Such sustained growth is seldom seen in anything that matters. That makes it hard for people to get their heads round what is going on. When it was a tenth of its current size ten years ago, solar power was still seen as marginal even by experts who knew how fast it had grown. The next ten-fold increase will be equivalent to multiplying the worldâs entire fleet of nuclear reactors by eight in less than the time it typically takes to build just a single one of them.
> Solar cells will in all likelihood be the single biggest source of electrical power on the planet by the mid 2030s. By the 2040s they may be the largest source not just of electricity but of all energy. On current trends, the all-in cost of the electricity they produce promises to be less than half as expensive as the cheapest available today. This will not stop climate change, but could slow it a lot faster. Much of the worldâincluding Africa, where 600m people still cannot light their homesâwill begin to feel energy-rich. That feeling will be a new and transformational one for humankind.
> To grasp that this is not some environmentalist fever dream, consider solar economics. As the cumulative production of a manufactured good increases, costs go down. As costs go down, demand goes up. As demand goes up, production increasesâand costs go down further. This cannot go on for ever; production, demand or both always become constrained. In earlier energy transitionsâfrom wood to coal, coal to oil or oil to gasâthe efficiency of extraction grew, but it was eventually offset by the cost of finding ever more fuel.
So! The transition is going fast (~1TW/year), and it is likely to continue to increase in speed (more solar manufacturing and battery storage will continue to be be built year over year, increasing annual production and deployment rates from today's rate(s)), based on all available data and observations. This is the good news to cheer. Nameplate and capacity factor arguments are meaningless in this context. We are at the hockey stick inflection point: look up.
> As the worldâs largest manufacturer of clean technologies, data on Chinaâs cleantech exports provide an important early insight into the pace and scale of the energy transition. In 2024, China produced around 80% of the worldâs solar PV modules and battery cells, and 70% of electric vehicles.
Trump could become an accidental environmental ally in the same way the 2008 credit crisis and Covid did. Just blunders in and in the wreckage might be something ok.
> True but having capacity allows for generation - doesn't work the other way around.
The issue is that comparing "capacity" as a percentage is misleading. A baseload generation source can have average generation above 90% of its rated capacity, solar at something like 25%, wind something like 25-40%. Which means that saying "nearly 50%" of capacity can imply something closer to 15% of generation, and potentially even less if the amount of local capacity is high, because then you get periods when renewable generation exceeds demand and the additional generation has nowhere to go, which effectively reduces the capacity factor even more.
And on the other side, natural gas peaker plants can have a capacity factor even lower than solar and wind because their explicit purpose is to only be used when demand exceeds supply from other sources, so that "nearly 50%" in a grid which is entirely renewables and peaker plants could actually imply more than 50% of total generation. This is much less common in existing grids but it makes looking at the nameplate capacity even more worthless because you can't just multiply it by a fixed factor to get the real number.
Whereas if they would just publish the percentage of actual generation, that's what people actually want to know. But then you'd have to say "13%" or "24%" or whatever the real number is, instead of "nearly 50%".
I'm too lazy to double check the numbers, but as far as I remember, Germany in order to increase it's average generation by 10% had to expand capacity by 70% in solar plus wind. With stats like this, there's a thin line between progress and waste. And all this while we have nuclear.
(How the world really works, Vaclav smil if anybody is less lazy than me)
I would say as electrician in Bavaria: there are enough empty roofs for solar. Especially in poorer neighborhoods. I saw similar numbers and they are scary: to reliably replace conventional power plant one needs 20x the power of wind and solar. And this hardware must be imported from China, there is no large scale production of solar equipment in Europe.
A lot of renewables have intermittent generation. If daytime electricity demand is already saturated, adding more solar panels increases capacity but doesn't increase generation (or to be more specific, it doesn't increase generation that actually fulfills demand).
We can also time shift many of the things we do. Does your fridge need to run between 3-5pm in the heat of summer? or can it make sure its a little cooler to avoid running then? (trivial example, probably not a good one)
I'm sure there are better examples, but your fridge idea doesn't work. Fridges already operate on the edge of freezing, so if you make it a little cooler you will ruin all your food. Also 3-5pm is peak hangry time.
This is why a major part of the solution is electric vehicles. Why put batteries in a warehouse and then run vehicles on petroleum when you can put batteries in a vehicle, install twice as many renewables because you now have more demand for electricity, and then charge the vehicles when generation is a large percentage of rated capacity and still have enough to run the rest of the grid when it's a smaller percentage?
So massively overprovision them. Itâs still cheaper than fossil fuels, especially if you price in all the externalities. Seems like all these hungry datacenters weâre building can soak up any excess capacity anyway.
What does cheap mean? You aren't paying for the same thing - a ccgt plant is super fast and works independent of the weather.
I'm in favour of having it but the reason why you need to over provision is because of the intermittency. This can also push out proper base load (e.g. nuclear) although it's not simple.
You have to think about the portfolio.
In Britain at least there is also a bit of a sleight of hand where the marginal costs are reported but not the CFD strike prices used to incentivise the buildout.
Makes sense - solar especially. It's just more financially smart to buy something that will generate electricity for 20-30 years with little to no maintenance than a plant that requires constant fuel, and is fairly complex mechanically with fluids and heat exchangers and turbines and so on. Panel efficiency keeps going up and prices keep going down, it's a snowball at this point.
That's why Putin attacked in 2022, and didn't wait any longer to build a stronger military. He knew he was on the clock as Europe slowly switched to renewables his fossil fuel leverage got weaker.
Unrelated, but doomer version of me expects that China will wait for the US to exhaust it's cruise missile supply bombing Iran, then move over Taiwan. Hope I'm wrong about this.
China would have no need to wait for the US to exhaust its cruise missile supply before attacking Taiwan. The amount of firepower that China can muster from the mainland is enough to completely overwhelm any amount of conventional firepower that the US can bring to bear in the region. All US ships and airbases closer than (and including) Guam are toast in a serious war.
> The amount of firepower that China can muster from the mainland is enough to completely overwhelm any amount of conventional firepower that the US can bring
A lesson we learn again in 2026: one canât seize and hold territory with air power alone.
China can almost certainly deny U.S. warships access to the Taiwan Strait. They can probably deny U.S. access to the South China Sea. But the U.S. (and Taiwan and Japan) can do the same back, similarly from a distance, and thatâs the equilibrium currently keeping the peace.
A lot of people who are cheering right now are going to be screaming bloody murder in 10-20yr when the "below this population density generation and storage makes more sense than grid" threshold creeps up into the lower end of suburban population densities and some industrial users can just buy the fields or hills around their factories and put up panels or wind turbines rather than negotiate with a bunch of entities.
Energy independence is a two way street. This is essentially a domestic internal soft power lever that is going to go away or be nerf'd.
Why is it bad if some industrial users of electricity buy fields around their factories and set up their own power generation there instead of hooking up to the power grid?
> industrial users can just buy the fields or hills around their factories and put up panels or wind turbines rather than negotiate with a bunch of entities.
Domestic users can just do the same. Some of us already have.
Yes, itâs not alway possible but a huge portion of domestic usage can be covered with a small install. Payback 5-10 years.
First: The same argument applies to suburban population, where autarky is even easier/cheaper than for industrial consumers: Just slap panels on the roof and a bunch of batteries into a shed, done. We won't even need much cheaper panels nor cells, really; it's mainly labor, integrator-margins and regulations that make this less (financially) attractive than the grid right now (pure cells are already in the $60/kWh range for single-digit quantities).
Second: If industrial consumers stop contributing towards electric grid costs and the general public dislikes it, you can just regulate against it, problem solved. But in practice governments already try to make the energy situation as appealing as possible for industry, so there is very little actually leveraged power that you really give up anyway.
You're absolutely right it applies to suburbia too, not just rural areas and industry in rural areas.
> you can just regulate against it, problem solved
I think that is exactly what you'll lose the ability to do. If Marvin Heemeyer didn't need the town's septic connection we wouldn't know his name.
A huge fraction of regulatory enforcement exists in the gray area of "the government is wrong, or their enforcement of it is wrong but it's cheaper to bend over and take it than to fight it through a courtroom". If farmer Johnson can slap up a building kit on his property and power it with stuff he bought online and doesn't need the power company, Joe Schmo can do the same with an ADU. Yeah, they'll both get dragged through court but $50-100k of court costs to be proven right is a much smaller threat when the project can be done and generating income for the duration of the court case (it also renders the typical tactic of dragging out such cases much less effective).
And at a slightly larger scale, if some business interest can negotiate purely with a municipality to take over some disused factory and bring it back into use and get their power via bunch of panels and not get bogged down with state permitting to get a transmission line and substation the state loses a huge number of levers over the business interest and also they lose levers to control poorer municipalities (who'd happily take the business). Once again, they'll get dragged through court by the state, but spending 5yr and $200k just to be right isn't a dealbreaker when your widget factory has been operating the whole time.
Yes, of course governments can do worse things if they feel like it, but they run into problems of political optics and will more or less instantly.
You already see this kind of thing in some of the highest cost areas. Certain demographics in the greater NYC area often do building and land development things this way. It costs the same at the end, but by doing it without asking you get to use it while the whole process runs.
The electrical utility DTE, in Michigan, required Google to do this for their new datacenter ("Project Cannoli") to avoid increasing consumer energy prices. They are building solar and battery storage to serve the load, as it is the cheapest and fastest new generation that can be built.
I see nothing wrong with power users committing to clean energy and storage to accelerate their development plans, or to allow them at all. I am unsure who is going to complain about this model. Lease or buy as much land as you need to deploy clean energy.
> Googleâs data center operations will be served by 2.7 gigawatts (GW) of new resources for the grid, including solar power, advanced storage technologies and demand flexibility. This Clean Capacity Acceleration Agreement with DTE (the same structure as the Clean Transition Tariff) will bring new, clean resources online, while supporting the stateâs transition away from coal-fired power. As part of our standard approach to building new data centers, Google will fully cover its electricity costs and infrastructure needs, helping to ensure that its growth protects local ratepayers and actively bolsters the long-term resilience of the stateâs electricity grid.
Solar capacity is always misleading because itâs intermittent. Capacity of a gas power plant canât be compared to capacity of a solar power plant, even though it sounds like you are comparing the same thing. Would love to know total kWh generated.
Yep. The key difference is that a gas power plant can be cut off completely at any time. For example if a trigger happy leader decided to cause military mayhem in an unpredictable region supplying a large proportion of the worldâs gas.
The sun, however, keeps on shining.
I didnât mean to compare them, implying that gas or anything else is better. Iâm a big fan of renewables, especially solar, but just wanted to bring this aspect up. Itâs confusing to me because I get excited when I see these numbers only to later deflate when I figure out the total generated kWh quantity. It would be great if there would be a âsyntheticâ calculation which takes into account the estimated generation and smoothing out using batteries, which would also take into account the extra cost of batteries. That would be a more apples to apples comparison both in terms of net generation and cost.
Whatâs the point of saying one stat is better than another, when all of them are meaningful in a different way? When renewables reach big numbers of TWh, someone will say âtotal generation is misleading if doesnât line up with demand; what matters is capacity for power when we actually need itâ.
I understand why people are downvoting you, but we still have a bit to go before renewables make up 50% of yearly electricity generation.
Not as far as youâd think though. According to [0] in 2024 it was 6.9% solar, 8.1% wind, and 14.3% hydro, I.e. 29% renewables. Given the trajectory I wouldnât be surprised if that total was ~33% in 2025.
Yes, but thats a bad extrapolation because per-capita electricity consumption was still rising then but is mostly flat/decreasing in western countries since 2000 or so, and the significant rise in reneably fraction mostly started after 2000.
The hydro fraction is also a really bad indicator in general, because it basically just reflects geography of a country and not really its effort to reduce CO2 emissions.
> The hydro fraction is also a really bad indicator in general, because it basically just reflects geography of a country and not really its effort to reduce CO2 emissions.
As a âclean green New Zealanderâ, your comment is perfect.
We trash our country in such appalling ways. The fact they there arenât many of us and that the easy way of getting power is hydro is coincidence, not a national conscience.
IEA had been predicting 2030 as peak fossil fuel usage up until recently. They revised it back upon Trump's election and shifting policy, but it's possible the Iran War has moved it forward again. Either way, it's within reach.
That being said, peak fossil fuels is the future date at which we are burning more than ever followed by the slow decrease. Meaning we are still accelerating CO2 emissions and even if we emit less, every emission is still cumulative so the march towards actually fixing the climate will only start at peak fossil fuels. We still need to remove all that GHG.
It takes time for statistical agencies to compile reports. I haven't yet found reports covering the growth in renewable generation (actual terawatt hours) for all of 2025. But this covers 3 quarters of the year:
https://ember-energy.org/latest-updates/solar-and-wind-growt...
In the first three quarters of 2025, solar generation rose by 498 TWh (+31%) and already surpassed the total solar output in all of 2024. Wind generation grew by 137 TWh (+7.6%). Together, they added 635 TWh, outpacing the rise in global electricity demand of 603 TWh (+2.7%).
The problem is in power transmission. Transmission fee is a big part of the cost. Anything helping for at home generation should be encouraged.
Right now plug in solar is starting to appear. It is big in Germany. Utah has passed a law to cut the red tapes to allow home owners to install plug in solar themselves. More states should follow.
>At the global level, 2025 also saw a sharp rebound in non-renewable additions, which nearly doubled compared to 2024," IRENA noted. China led that drive, with 100 GW of non-renewable capacity added last year, most of which was coal.
Why is China adding so many new generation plants powered by coal? On this and other forums, I see claims all the time that solar is cheaper than coal. As the world's leading producer of solar panels, you would think that they would utilize it even more if those claims are true.
Is it just the need for power when the sun is not shining? Or is it something else?
There's a recent AP article talking about this some (I don't know enough to know the quality of the article): https://apnews.com/article/china-coal-solar-climate-carbon-e...
My understanding is that China is planning to build a coal-backed renewable grid. Renewables, including storage, will provide the majority of the electricity generation, and then coal will step in when renewables aren't available. This involves building modern coal plants that can be spun up and down as needed, and then paying them not to generate. This is why actual emissions have plateaued and dropped, even as new coal capacity comes online.
We are (or were) doing something similar in the US, just using natural gas as the fuel rather than coal.
Inertia I imagine. Planning cycles can be 10, 20 years, perhaps longer for big infrastructure projects.
Wait this is actually amazing, I had no idea it was that high. I canât even believe what the US admin is doing, this is clearly the winning technology.

OK, but what if someone looked at the rated capacity of all trucks and noted that in the last 5 years it went up by 24%, 22%, 28%, 54%, and 45%? That would strongly suggest that the amount trucks actually being used is growing rapidly because people aren't going to be buying new trucks unless they have to.
This is a common rebuttal, but not grounded in reality. Even assuming ~20% capacity factor for "apples to apples" comparison to legacy thermal and nuclear, solar and batteries are the cheapest form of power to install. Current geopolitical events spiking LNG costs make the math even more favorable towards renewables.

Legacy power is ridiculously expensive in comparison. Who will invest in fossil gas generation when ~20% of LNG exports have been taken offline for the next 3-5 years?

Fossil fuels are over, it's just how fast we get to "done." Enough sunlight falls on the Earth in 30-60 minutes to power humanity for a year. Solar PV and battery manufacturing continues to spool up, and year by year, more fossil generation is pushed out.
California is routinely operating at 80% renewables, 90% low carbon generation during daylight hours as they work towards installing battery storage to replace their fossil generation (~52GW target by 2045), for example, while having plans for 10s of GWs of additional solar to come online over the next decade.

> This is a common rebuttal, but not grounded in reality. Even assuming ~20% capacity factor for "apples to apples" comparison to legacy thermal and nuclear, solar and batteries are the cheapest form of power to install.
I looked it up because I was curious, according to Wikipedia average PV capacity factor is 25 % in USA, 10 % in the UK or Germany.
Nuclear has 88 % capacity factor worldwide. Meaning to replace 1 GW of nuclear installed capacity you need 8.8 GW of PV installed capacity in Germany or 3.5 GW of PV installed capacity in US.
Which might still be economically worth it, I don't know. But it is a number that surprised it.
It takes ~10 years to build a new nuclear generator from breaking ground to first kw to the grid, and tens of billions of dollars or euros. Germany deploys ~2GW/month of solar, the US ~4-5GW/month. Total global nuclear generation capacity is ~380GW as of this comment. At current global solar PV deployment rates, even assuming capacity factor delta between solar and nuclear, you could replace total global nuclear generation with ~18 months of solar PV deployment.
Yes, the biggest advantage of solar and wind is that they can be built as many small projects, instead of few gigaprojects we seem to have lost the ability to execute in the West.
I wish I didn't live in coal and NIMBY land.
> I wish I didn't live in coal and NIMBY land
Money will eventually win the war. Depressing way to get there but this crisis will accelerate the change.
Nuclear fills a base load role better than solar+battery though, imo.
A healthy power network will have a variety of generations sources available.
Modern grids favour flexibility over fixed baseload generation (like nuclear) though. When you turn off a nuclear power plant its operating costs basically stay the same, which is horrible when you could cover your whole consumption with basically free solar/wind.
Compare the price and carbon density of the French electricity grid with that of California to understand why that rebuttal is justified.
France had to nationalize EDF due to the exorbitant cost of their nuclear fleet, and they cannot get a reactor built within reasonable capital costs. Spain plans to deprecate their remaining nuclear for renewables for similar reasons. California will achieve a low carbon generation profile for far cheaper than it cost France (refer to the Lazard LCOE data product I've cited in my other comment in this thread).

Still, she said, there is a reasonable chance this goal may take longer than expected and âextending the life of the nuclear fleet can prove as an insurance for these delays.â) (My note: As of this comment, Spain has 7.12GW of nuclear generation capacity per ree.es, and assuming ~2GW/month deployment rate seen in Germany, could replace this capacity with solar and batteries in ~17 months; per Electricity Maps, only 15.45% of Spain's electrical generation over the last twelve months has been sourced from this nuclear: https://app.electricitymaps.com/map/zone/ES/12mo/monthly)
> France had to nationalize EDF due to the exorbitant cost of their nuclear fleet
That's just wrong.
EDF nuclear fleet is highly profitable with around 92TWh exported in 2025 and more than 5 Billions of benefits for the country and the company.
https://www.sfen.org/rgn/le-nucleaire-en-chiffres-923-twh-de...
The reason EDF had to be nationalized is because the government used the company as a "price shield" to protect consumer against energy price rise on the European market in 2022 with a mechanism named TRV (Tarif RĂŠgulĂŠ vente). That digged up EDF dept tremendously.
> Spain plans to deprecate their remaining nuclear for renewables for similar reasons
Span deprecated their nuclear government because their current Socialist government is aligned with Ecologists that are, like everywhere in Europe, antinuclear.
Additionally, the lack of spinning generator in Spain is currently partially what caused the Blackout in Spain in 2025 due to a lack of inertia in the system.
> EDF fleet upkeep will cost over 100 billion euros by 2035, court of auditors says
This is over 25 years and will prolong-ate the lifetime of the 56 reactors by 20 more years. These produce 70% of the country need in electricity.
In comparison, the German energiewende cost 400 billions for 37% of electricity of 2025 produced by solar and wind. With production medium that will need to be entirely renewed in 20 years.
> California will achieve a low carbon generation profile for far cheaper than it cost France (refer to the Lazard LCOE
That is also wrong.
Because LCOE calculation does not take into consideration the price of the grid consolidating necessary for renewable nor the necessity of backup generation in case of dunkleflaute.
I didn't say they weren't cheap. I said you were being misleading. I'm not rebutting your thesis. I'm rebutting your defense of it.
They're so cheap they get over-provisioned on purpose. Can you imagine some guy speci'ng switchgear and transmission lines for a coal or gas plant that can't handle the plant running full tilt? Yeah me either. But that's exactly how it's done for renewables because that's where the sweet spot of cost-benifit is.
A dozen 10mw turbines might be fed through 100mw of transmission hardware. They can never produce their rated 120mw because liquid copper would happen if they did. But they were intentionally provisioned that way so that based on weather patterns and whatnot they'd be able to expect say 80mw a certain number of days per year.
There are untold numbers of renewable installations out there that cannot supply their nameplate capacity to the grid in such a manner.
There is nothing wrong with over provisioning cheap renewable power generation when it is economically superior to building fossil assets that will end up stranded. As long as grid demand is met and it is cheaper to build renewables and batteries to do it, it will be done, and that is the path we're on.
If gas plants cannot economically compete, they will not be built or fired. And the evidence shows they cannot compete, regardless of their competing capacity factor and dispatchability.
Do you have some links to how someone scaled up storage? I know that scaling up solar is easy, but I don't know of any nation that build significant storage.
https://about.bnef.com/insights/clean-energy/global-energy-s...

https://hn.algolia.com/?dateRange=all&page=0&prefix=false&qu...
You are still arguing against a strawman. Cucumber3732842 is just saying that nameplate capacity is a systematically flawed metric when comparing renewable generation, because their capacity factor is consistently lower than for conventional plants.
A better metric would simply be annual production, where we're in the ~30% range globally (https://ourworldindata.org/grapher/share-electricity-renewab...). Even that comparison portraits renewables very favorably, because dispatchable power is easier to handle than the same output from intermittent sources.
If you look beyond electricity (heating/total primary energy use) the picture gets even worse.
This is not an argument against renewables, this is against premature cheering and misleading use of numbers.
I think you misunderstand. We are cheering trajectories, not the point in time. Renewables and storage will continue to be deployed, fossil fuels will remain expensive, and build outs will continue over the next decade or two. If these trajectories hold, and growth rates continue to grow for clean energy deployments, what happens? The outcome is obvious, is it not?
The thesis is simply this chart: https://ourworldindata.org/grapher/installed-solar-pv-capaci...
Of course, there is nuance, but the facts are that in the next 10-20 years, renewables and storage will have destroyed demand for fossil fuels for electrical generation. That's progress. We might go faster or slower, depending on policy and other factors, but this is the trajectory we are currently on, based on the data presented in this piece.
The Economist wrote a piece explaining this, if that is helpful:
The exponential growth of solar power will change the world - https://www.economist.com/leaders/2024/06/20/the-exponential... | https://archive.today/lp9pZ - June 20th, 2024
> To call solar powerâs rise exponential is not hyperbole, but a statement of fact. Installed solar capacity doubles roughly every three years, and so grows ten-fold each decade. Such sustained growth is seldom seen in anything that matters. That makes it hard for people to get their heads round what is going on. When it was a tenth of its current size ten years ago, solar power was still seen as marginal even by experts who knew how fast it had grown. The next ten-fold increase will be equivalent to multiplying the worldâs entire fleet of nuclear reactors by eight in less than the time it typically takes to build just a single one of them.
> Solar cells will in all likelihood be the single biggest source of electrical power on the planet by the mid 2030s. By the 2040s they may be the largest source not just of electricity but of all energy. On current trends, the all-in cost of the electricity they produce promises to be less than half as expensive as the cheapest available today. This will not stop climate change, but could slow it a lot faster. Much of the worldâincluding Africa, where 600m people still cannot light their homesâwill begin to feel energy-rich. That feeling will be a new and transformational one for humankind.
> To grasp that this is not some environmentalist fever dream, consider solar economics. As the cumulative production of a manufactured good increases, costs go down. As costs go down, demand goes up. As demand goes up, production increasesâand costs go down further. This cannot go on for ever; production, demand or both always become constrained. In earlier energy transitionsâfrom wood to coal, coal to oil or oil to gasâthe efficiency of extraction grew, but it was eventually offset by the cost of finding ever more fuel.
So! The transition is going fast (~1TW/year), and it is likely to continue to increase in speed (more solar manufacturing and battery storage will continue to be be built year over year, increasing annual production and deployment rates from today's rate(s)), based on all available data and observations. This is the good news to cheer. Nameplate and capacity factor arguments are meaningless in this context. We are at the hockey stick inflection point: look up.
I am from the USA, and from the numbers it looks like China will save the planet.
Strongly agree. China will soak the world in clean tech. It is a component of their five year plans.
https://ember-energy.org/data/china-cleantech-export-data/
> As the worldâs largest manufacturer of clean technologies, data on Chinaâs cleantech exports provide an important early insight into the pace and scale of the energy transition. In 2024, China produced around 80% of the worldâs solar PV modules and battery cells, and 70% of electric vehicles.
Clean tech printer goes brrr.
The Trump administration is secretly the head of a renewable energy accelerationist front, or at least that's the effect in practice.
Trump could become an accidental environmental ally in the same way the 2008 credit crisis and Covid did. Just blunders in and in the wreckage might be something ok.
> The Trump administration is secretly the head of a renewable energy accelerationist front
"accelerationist" yes, not sure about the other parts.
Well see, we're sick of winning.
Capacity doesnât matter, generation does.
True but having capacity allows for generation - doesn't work the other way around.
AKA the forward march of progress.
> True but having capacity allows for generation - doesn't work the other way around.
The issue is that comparing "capacity" as a percentage is misleading. A baseload generation source can have average generation above 90% of its rated capacity, solar at something like 25%, wind something like 25-40%. Which means that saying "nearly 50%" of capacity can imply something closer to 15% of generation, and potentially even less if the amount of local capacity is high, because then you get periods when renewable generation exceeds demand and the additional generation has nowhere to go, which effectively reduces the capacity factor even more.
And on the other side, natural gas peaker plants can have a capacity factor even lower than solar and wind because their explicit purpose is to only be used when demand exceeds supply from other sources, so that "nearly 50%" in a grid which is entirely renewables and peaker plants could actually imply more than 50% of total generation. This is much less common in existing grids but it makes looking at the nameplate capacity even more worthless because you can't just multiply it by a fixed factor to get the real number.
Whereas if they would just publish the percentage of actual generation, that's what people actually want to know. But then you'd have to say "13%" or "24%" or whatever the real number is, instead of "nearly 50%".
I'm too lazy to double check the numbers, but as far as I remember, Germany in order to increase it's average generation by 10% had to expand capacity by 70% in solar plus wind. With stats like this, there's a thin line between progress and waste. And all this while we have nuclear. (How the world really works, Vaclav smil if anybody is less lazy than me)
> With stats like this, there's a thin line between progress and waste.
Humanity does far more wasteful things than build some extra solar panels.
I would say as electrician in Bavaria: there are enough empty roofs for solar. Especially in poorer neighborhoods. I saw similar numbers and they are scary: to reliably replace conventional power plant one needs 20x the power of wind and solar. And this hardware must be imported from China, there is no large scale production of solar equipment in Europe.
A lot of renewables have intermittent generation. If daytime electricity demand is already saturated, adding more solar panels increases capacity but doesn't increase generation (or to be more specific, it doesn't increase generation that actually fulfills demand).
Unless you add battery storage, which is increasingly the case:
https://pv-magazine-usa.com/2026/02/25/solar-and-storage-to-...
We can also time shift many of the things we do. Does your fridge need to run between 3-5pm in the heat of summer? or can it make sure its a little cooler to avoid running then? (trivial example, probably not a good one)
I'm sure there are better examples, but your fridge idea doesn't work. Fridges already operate on the edge of freezing, so if you make it a little cooler you will ruin all your food. Also 3-5pm is peak hangry time.
A modern fridge also uses approximately five watts, on average. There are far better targets.
Demand response for things like hotel air conditioning is a thing: https://www.bbc.co.uk/news/science-environment-23343211
Batteries are also getting cheaper and cheaper
This is why a major part of the solution is electric vehicles. Why put batteries in a warehouse and then run vehicles on petroleum when you can put batteries in a vehicle, install twice as many renewables because you now have more demand for electricity, and then charge the vehicles when generation is a large percentage of rated capacity and still have enough to run the rest of the grid when it's a smaller percentage?
And they are the only real solution. Demand fitting production is never going to work unless we give up all the autonomy.
You have to massively overprovision some renewables
So massively overprovision them. Itâs still cheaper than fossil fuels, especially if you price in all the externalities. Seems like all these hungry datacenters weâre building can soak up any excess capacity anyway.
What does cheap mean? You aren't paying for the same thing - a ccgt plant is super fast and works independent of the weather.
I'm in favour of having it but the reason why you need to over provision is because of the intermittency. This can also push out proper base load (e.g. nuclear) although it's not simple.
You have to think about the portfolio.
In Britain at least there is also a bit of a sleight of hand where the marginal costs are reported but not the CFD strike prices used to incentivise the buildout.
Can't have generation without capacity...
Makes sense - solar especially. It's just more financially smart to buy something that will generate electricity for 20-30 years with little to no maintenance than a plant that requires constant fuel, and is fairly complex mechanically with fluids and heat exchangers and turbines and so on. Panel efficiency keeps going up and prices keep going down, it's a snowball at this point.
Relevant xkcd: https://xkcd.com/3226/
>it's a snowball at this point.
That's why Putin attacked in 2022, and didn't wait any longer to build a stronger military. He knew he was on the clock as Europe slowly switched to renewables his fossil fuel leverage got weaker.
Unrelated, but doomer version of me expects that China will wait for the US to exhaust it's cruise missile supply bombing Iran, then move over Taiwan. Hope I'm wrong about this.
China would have no need to wait for the US to exhaust its cruise missile supply before attacking Taiwan. The amount of firepower that China can muster from the mainland is enough to completely overwhelm any amount of conventional firepower that the US can bring to bear in the region. All US ships and airbases closer than (and including) Guam are toast in a serious war.
> The amount of firepower that China can muster from the mainland is enough to completely overwhelm any amount of conventional firepower that the US can bring
A lesson we learn again in 2026: one canât seize and hold territory with air power alone.
China can almost certainly deny U.S. warships access to the Taiwan Strait. They can probably deny U.S. access to the South China Sea. But the U.S. (and Taiwan and Japan) can do the same back, similarly from a distance, and thatâs the equilibrium currently keeping the peace.
worth to keep in mind electricity usage != energy usage. We are far away from replacing oil, lpg.
This is far higher than I expected: a much needed, remarkably good reason to be cheerful about the future after all !
A lot of people who are cheering right now are going to be screaming bloody murder in 10-20yr when the "below this population density generation and storage makes more sense than grid" threshold creeps up into the lower end of suburban population densities and some industrial users can just buy the fields or hills around their factories and put up panels or wind turbines rather than negotiate with a bunch of entities.
Energy independence is a two way street. This is essentially a domestic internal soft power lever that is going to go away or be nerf'd.
Why is it bad if some industrial users of electricity buy fields around their factories and set up their own power generation there instead of hooking up to the power grid?
> industrial users can just buy the fields or hills around their factories and put up panels or wind turbines rather than negotiate with a bunch of entities.
Domestic users can just do the same. Some of us already have.
Yes, itâs not alway possible but a huge portion of domestic usage can be covered with a small install. Payback 5-10 years.
I honestly don't see a big problem with that.
First: The same argument applies to suburban population, where autarky is even easier/cheaper than for industrial consumers: Just slap panels on the roof and a bunch of batteries into a shed, done. We won't even need much cheaper panels nor cells, really; it's mainly labor, integrator-margins and regulations that make this less (financially) attractive than the grid right now (pure cells are already in the $60/kWh range for single-digit quantities).
Second: If industrial consumers stop contributing towards electric grid costs and the general public dislikes it, you can just regulate against it, problem solved. But in practice governments already try to make the energy situation as appealing as possible for industry, so there is very little actually leveraged power that you really give up anyway.
You're absolutely right it applies to suburbia too, not just rural areas and industry in rural areas.
> you can just regulate against it, problem solved
I think that is exactly what you'll lose the ability to do. If Marvin Heemeyer didn't need the town's septic connection we wouldn't know his name.
A huge fraction of regulatory enforcement exists in the gray area of "the government is wrong, or their enforcement of it is wrong but it's cheaper to bend over and take it than to fight it through a courtroom". If farmer Johnson can slap up a building kit on his property and power it with stuff he bought online and doesn't need the power company, Joe Schmo can do the same with an ADU. Yeah, they'll both get dragged through court but $50-100k of court costs to be proven right is a much smaller threat when the project can be done and generating income for the duration of the court case (it also renders the typical tactic of dragging out such cases much less effective).
And at a slightly larger scale, if some business interest can negotiate purely with a municipality to take over some disused factory and bring it back into use and get their power via bunch of panels and not get bogged down with state permitting to get a transmission line and substation the state loses a huge number of levers over the business interest and also they lose levers to control poorer municipalities (who'd happily take the business). Once again, they'll get dragged through court by the state, but spending 5yr and $200k just to be right isn't a dealbreaker when your widget factory has been operating the whole time.
Yes, of course governments can do worse things if they feel like it, but they run into problems of political optics and will more or less instantly.
You already see this kind of thing in some of the highest cost areas. Certain demographics in the greater NYC area often do building and land development things this way. It costs the same at the end, but by doing it without asking you get to use it while the whole process runs.
The electrical utility DTE, in Michigan, required Google to do this for their new datacenter ("Project Cannoli") to avoid increasing consumer energy prices. They are building solar and battery storage to serve the load, as it is the cheapest and fastest new generation that can be built.
I see nothing wrong with power users committing to clean energy and storage to accelerate their development plans, or to allow them at all. I am unsure who is going to complain about this model. Lease or buy as much land as you need to deploy clean energy.

Of course, huge investment need to be paid for somehow.
Still a worthwhile investment in most case.
Solar capacity is always misleading because itâs intermittent. Capacity of a gas power plant canât be compared to capacity of a solar power plant, even though it sounds like you are comparing the same thing. Would love to know total kWh generated.
Yep. The key difference is that a gas power plant can be cut off completely at any time. For example if a trigger happy leader decided to cause military mayhem in an unpredictable region supplying a large proportion of the worldâs gas. The sun, however, keeps on shining.
I didnât mean to compare them, implying that gas or anything else is better. Iâm a big fan of renewables, especially solar, but just wanted to bring this aspect up. Itâs confusing to me because I get excited when I see these numbers only to later deflate when I figure out the total generated kWh quantity. It would be great if there would be a âsyntheticâ calculation which takes into account the estimated generation and smoothing out using batteries, which would also take into account the extra cost of batteries. That would be a more apples to apples comparison both in terms of net generation and cost.
Whatâs the point of saying one stat is better than another, when all of them are meaningful in a different way? When renewables reach big numbers of TWh, someone will say âtotal generation is misleading if doesnât line up with demand; what matters is capacity for power when we actually need itâ.
> what matters is capacity for power when we actually need it
uh,...yea?
I understand why people are downvoting you, but we still have a bit to go before renewables make up 50% of yearly electricity generation.
Not as far as youâd think though. According to [0] in 2024 it was 6.9% solar, 8.1% wind, and 14.3% hydro, I.e. 29% renewables. Given the trajectory I wouldnât be surprised if that total was ~33% in 2025.
[0]: https://ourworldindata.org/grapher/electricity-prod-source-s...
Sadly, my country (Uruguay) is not on that map. Right now, ~99% of the energy we get comes from renewables.
By your definition/chart, we were 0% solar, 0% wind, and 20% hydro in 1985 for 20% total renewables. So, 20% -> 29% in 4 decades
Yes, but thats a bad extrapolation because per-capita electricity consumption was still rising then but is mostly flat/decreasing in western countries since 2000 or so, and the significant rise in reneably fraction mostly started after 2000.
The hydro fraction is also a really bad indicator in general, because it basically just reflects geography of a country and not really its effort to reduce CO2 emissions.
> The hydro fraction is also a really bad indicator in general, because it basically just reflects geography of a country and not really its effort to reduce CO2 emissions.
As a âclean green New Zealanderâ, your comment is perfect.
We trash our country in such appalling ways. The fact they there arenât many of us and that the easy way of getting power is hydro is coincidence, not a national conscience.
IEA had been predicting 2030 as peak fossil fuel usage up until recently. They revised it back upon Trump's election and shifting policy, but it's possible the Iran War has moved it forward again. Either way, it's within reach.
That being said, peak fossil fuels is the future date at which we are burning more than ever followed by the slow decrease. Meaning we are still accelerating CO2 emissions and even if we emit less, every emission is still cumulative so the march towards actually fixing the climate will only start at peak fossil fuels. We still need to remove all that GHG.
